Introduction

Under Philippine law, a contract is not valid merely because two people agreed to something. The parties must have capacity to give consent, the object must be lawful, and the cause or consideration must be valid. When the contracting parties are minors, the most important issue is capacity.

A minor is a person below eighteen years of age. As a general rule, minors cannot give full legal consent to contracts in the same way adults can. Because of this, contracts entered into by minors are usually not treated as fully binding and enforceable in the ordinary way.

The key rule is:

A contract entered into by a minor is generally voidable, not automatically void, unless the law makes it void or another defect exists.

When both parties are minors, the situation becomes more complicated because both parties may lack legal capacity. The contract may be vulnerable to annulment by either minor, through the proper representative, subject to rules on ratification, restitution, necessaries, estoppel in limited situations, and protection of minors.

This article explains the validity, enforceability, consequences, remedies, and practical legal issues involving contracts between minors in the Philippines.

1. Who Is a Minor Under Philippine Law?

A minor is a person below eighteen years old.

In the Philippines, the age of majority is generally eighteen. A person who has reached eighteen years of age is legally considered an adult and generally has full civil capacity to enter into contracts, subject to other legal limitations.

A person below eighteen is generally under parental authority or guardianship and has limited capacity to contract.

Examples of minors:

a 17-year-old senior high school student;
a 16-year-old online seller;
a 15-year-old who buys a motorcycle;
a 14-year-old who signs a rental agreement;
a 13-year-old who enters a gaming account sale;
two 17-year-olds who sign a loan agreement with each other;
two minors who agree to sell gadgets, bicycles, pets, digital accounts, or collectibles to each other.

The law protects minors because they are presumed to lack full judgment, maturity, and legal capacity to bind themselves in civil transactions.

2. Essential Requisites of a Contract

Under the Civil Code, a valid contract generally requires:

consent of the contracting parties;
object certain which is the subject matter of the contract; and
cause of the obligation established.

When the issue involves minors, the usual defect concerns consent.

A minor may physically agree, sign, click “accept,” receive money, or deliver an item. But legally, the minor’s consent may be defective because the law does not treat a minor as having full contractual capacity.

Thus, even if both minors “agreed,” the law may still allow the contract to be annulled.

3. Capacity to Give Consent

Not everyone can give legally effective consent.

Persons who generally cannot give full consent to a contract include:

unemancipated minors;
insane or demented persons;
deaf-mutes who do not know how to write, under the traditional Civil Code wording;
and persons otherwise declared incapable by law.

In modern practical terms, minors are the most common category.

The lack of capacity does not always make the contract void from the beginning. Many contracts entered into by minors are voidable, meaning they are valid and produce legal effects unless annulled by the proper party.

4. Void, Voidable, Unenforceable, and Rescissible Contracts

To understand contracts between minors, it is important to distinguish different defective contracts.

Void contract

A void contract has no legal effect from the beginning. It cannot generally be ratified. Examples include contracts with an illegal object or cause.

Voidable contract

A voidable contract is valid until annulled. It may be ratified. Contracts entered into by minors are commonly voidable.

Unenforceable contract

An unenforceable contract cannot be enforced in court unless ratified. Examples may involve certain contracts entered into without authority or those covered by the Statute of Frauds.

Rescissible contract

A rescissible contract is valid but may be rescinded because of damage or lesion in cases provided by law.

For minors, the usual classification is voidable, unless the contract is void for another reason.

5. General Rule: Contracts Entered Into by Minors Are Voidable

A contract entered into by a minor is generally voidable because one party is incapable of giving legal consent.

A voidable contract:

is binding unless annulled;
may be annulled by the minor or the minor’s legal representative;
may be ratified when the minor reaches majority;
may produce effects before annulment;
may require restitution if annulled;
may be confirmed by conduct after reaching majority;
cannot usually be attacked by the adult party on the ground of the minor’s incapacity;
is designed to protect the minor, not to punish the minor.

The law allows annulment because minors should not be permanently bound by obligations they were not legally capable of understanding or assuming.

6. What if Both Parties Are Minors?

When both parties are minors, both lack full legal capacity.

A contract between two minors is generally voidable at the instance of either minor, acting through the proper legal representative or upon reaching majority, subject to legal rules.

For example:

A 16-year-old sells a laptop to a 17-year-old.
A 15-year-old borrows money from a 16-year-old.
Two 17-year-olds sign an agreement to split business profits.
A 14-year-old sells an online game account to a 15-year-old.
A 16-year-old leases a room to another minor.
Two minors agree to buy and sell a motorcycle.

In these cases, either minor may later claim lack of capacity. But the consequences will depend on whether the contract was performed, whether the object still exists, whether the transaction involved necessaries, whether there was fraud, whether parents or guardians consented, and whether the minor later ratified the contract after reaching majority.

7. Is a Contract Between Minors Automatically Void?

Usually, no.

A contract between minors is not automatically void solely because the parties are minors. The usual rule is that it is voidable.

This means that, until annulled, the contract may have practical effects. Money may be paid, goods may be delivered, possession may be transferred, and parties may act as if the contract exists.

However, because both parties are minors, enforcement is fragile. Either side may later challenge the contract.

The contract may become void if another defect exists, such as:

illegal object;
illegal cause;
impossible object;
simulated or fictitious contract;
contract contrary to law, morals, good customs, public order, or public policy;
gambling or wagering prohibited by law;
sale of illegal drugs, weapons, or contraband;
contract involving sexual exploitation or immoral consideration;
contract requiring criminal acts;
contract prohibited by child protection laws;
contract violating labor laws on child employment;
or any agreement declared void by law.

Minority makes the contract voidable; illegality may make it void.

8. Who May Annul a Minor’s Contract?

The action for annulment may generally be brought by:

the minor, upon reaching majority;
the minor’s parent;
the minor’s legal guardian;
the minor’s legal representative;
or a duly authorized person acting for the minor’s interest.

When both parties are minors, each side may have a right to seek annulment.

The purpose is protection. The law gives the remedy to the incapacitated party, not to the party who wants to take advantage of the minor’s incapacity.

9. Can the Other Party Use Minority as a Defense?

If both parties are minors, either party may invoke minority.

If one party is an adult and the other is a minor, the adult generally cannot use the minor’s incapacity to escape the contract where the law protects the minor. The right to annul belongs to the incapacitated party, not to the capable party who contracted with the minor.

In a contract between minors, both are protected. The court must balance their respective interests.

10. Ratification After Reaching Majority

A voidable contract may be ratified.

Ratification means confirming a contract that was previously defective because of incapacity.

A minor may ratify the contract after reaching eighteen years of age.

Ratification may be:

express, such as signing a written confirmation; or
implied, such as accepting benefits, continuing to perform, making payments, demanding performance, or failing to object despite knowledge of the defect.

Once validly ratified, the right to annul is generally extinguished.

Example:

A 17-year-old buys a camera from another 17-year-old on installment. After turning 18, the buyer continues making payments and confirms that the sale will proceed. This may amount to ratification.

If both parties were minors, each may need to ratify after reaching majority for the contract to become secure against annulment by that party.

11. Can Parents or Guardians Ratify the Contract?

Parents or guardians may act for the minor in certain matters. However, the effect of parental consent depends on the nature of the contract.

A parent or guardian may:

consent to a transaction for the minor;
manage the minor’s property;
approve ordinary transactions;
represent the minor in litigation;
recover property for the minor;
settle claims with court approval when necessary;
or seek annulment.

However, parents do not have unlimited power to dispose of a minor’s property or bind a minor to substantial obligations. Some acts may require court approval, especially when involving sale, mortgage, compromise, or disposition of significant property belonging to the minor.

Thus, parental involvement may strengthen enforceability, but it does not automatically validate every transaction.

12. Restitution After Annulment

If a contract is annulled, the parties may need to return what they received.

The general principle is restoration: parties should be returned as much as possible to their original situation.

However, when a minor is involved, restitution is subject to protective rules.

A minor may be required to return only to the extent that the minor was benefited. If the minor no longer has the money or property and was not benefited, recovery may be limited.

This prevents adults from defeating the protective purpose of the law. But when both parties are minors, courts may need to equitably determine what each minor must return.

Example:

A 16-year-old sells a phone to a 15-year-old for ₱10,000. The buyer returns the phone and asks for the money back. If the seller still has the money, return is straightforward. If the seller already spent it on food, school needs, or family necessities, the outcome may require deeper analysis.

13. The Rule on Necessaries

A minor may be liable for necessaries.

Necessaries are things reasonably needed for support, such as:

food;
clothing;
shelter;
medical care;
education-related needs;
basic transportation;
hygiene items;
and other essentials suitable to the minor’s circumstances.

If a minor contracts for necessaries, the law may allow recovery of a reasonable value, even if the contract itself is affected by incapacity.

The rationale is that minors need access to essential goods and services. Sellers or providers should not always be denied payment for necessities actually supplied.

However, the claim is usually limited to the reasonable value of the necessaries, not necessarily the full contract price if excessive.

14. Contracts Between Minors for Necessaries

If one minor supplies necessaries to another minor, enforceability may still be complicated.

Example:

A 17-year-old pays for emergency medicine for a 16-year-old friend, and the friend promises to repay.

The creditor is also a minor, but the transaction concerns necessaries. The law may allow recovery based on unjust enrichment, reimbursement, or reasonable value, especially if the debtor-minor was actually benefited.

However, parents or guardians may also be involved because support obligations may belong to parents or persons legally bound to support the minor.

15. Sale of Personal Property Between Minors

Sales between minors are common in daily life.

Examples:

phone sale;
bicycle sale;
clothing resale;
shoes or bags;
books;
gadgets;
game consoles;
collectibles;
school supplies;
pets;
online accounts;
digital items;
secondhand items.

These contracts are generally voidable due to minority.

Practical consequences:

If fully performed and no dispute arises, the transaction may remain undisturbed.
If one minor seeks annulment, return of the item and price may be required.
If the item was damaged, lost, or resold, restitution becomes complicated.
If the object is illegal or prohibited, the contract may be void.
If parents demand return, the other minor may need to return the property if still in possession.

Small everyday purchases are often tolerated as practical necessities of daily life, but legally significant transactions remain vulnerable.

16. Sale of Real Property by or Between Minors

A minor generally cannot validly sell real property without proper legal representation and required authority.

A contract where a minor sells land, a house, condominium unit, or hereditary share is highly vulnerable.

If both parties are minors, a sale of real property between them is especially problematic because:

both lack capacity;
real property transactions require formalities;
land registration rules may apply;
notarization does not cure incapacity;
tax declarations and titles require legal capacity;
guardianship or court approval may be required;
parents may lack authority to sell without court approval;
the Register of Deeds may not accept documents;
the contract may be voidable or unenforceable depending on form and authority;
fraud or exploitation may be present.

A minor’s real property should generally be dealt with only through parents, guardians, and court-approved processes when required.

17. Loan Agreements Between Minors

Loans between minors are usually voidable.

Examples:

one minor lends ₱5,000 to another;
two minors sign a written promissory note;
a minor borrows money for a gadget;
a minor borrows money for school expenses;
one minor charges interest to another.

Because both parties are minors, the creditor-minor and debtor-minor both have limited capacity.

Possible outcomes:

the loan may be annulled;
the borrower may be required to return money still possessed or beneficially used;
interest may be denied if unfair, usurious, exploitative, or not validly agreed;
parents may become involved if they authorized or benefited from the transaction;
if money was used for necessaries, reimbursement may be more likely;
if the transaction was gambling, illegal, or exploitative, recovery may be denied or limited.

A minor lending money should not assume the agreement is fully enforceable.

18. Interest on Loans Between Minors

Interest requires a lawful basis. Even between adults, interest must comply with legal rules and must generally be stipulated in writing.

Between minors, interest is even more vulnerable.

A court may refuse to enforce:

excessive interest;
hidden penalties;
compound interest;
daily interest schemes;
“5-6” style arrangements;
threats or coercive collection;
interest imposed through online lending groups;
penalty charges that are oppressive;
or interest in a voidable transaction not properly ratified.

The principal amount may be treated differently from interest, especially if the borrower actually received and benefited from the money.

19. Online Contracts Between Minors

Many contracts between minors now occur online.

Examples:

buying and selling mobile phones through social media;
game account sales;
digital art commissions;
streaming equipment sale;
online tutoring agreements;
buy-and-sell groups;
crypto or NFT transactions;
social media account sales;
in-game item sales;
online lending;
prepaid load or e-wallet transfers;
marketplace transactions;
content creation agreements;
influencer collaborations.

The fact that the transaction is online does not remove the issue of minority. A minor still lacks full legal capacity, even if the minor clicked, typed, recorded, or electronically signed.

Screenshots, chat logs, payment records, delivery receipts, and e-wallet confirmations may prove that an agreement happened, but they do not necessarily prove legal capacity.

20. E-Wallet and Digital Payment Transactions

Minors often use e-wallets, bank apps, or payment platforms. The payment record may show transfer of money, but the underlying contract may still be voidable.

If a dispute arises, evidence may include:

transaction history;
screenshots;
account names;
mobile numbers;
delivery proof;
chat conversations;
platform terms;
parent or guardian authorization;
and proof of age.

If the platform itself prohibits minors from opening accounts or transacting without parental consent, separate issues may arise under the platform’s terms.

21. Contracts for Digital Accounts and Game Items

Minors frequently buy and sell digital accounts, skins, game credits, virtual items, or online profiles.

These transactions may be problematic because:

both parties may be minors;
the object may violate platform terms;
accounts may not be legally transferable;
ownership of digital assets may be limited;
the seller may recover or reclaim the account;
scams are common;
parents may dispute the transaction;
payment platforms may reverse payments;
the contract may be voidable;
the object may not be legally recognized as freely alienable property.

Even if money was paid, the buyer may have limited remedies if the transaction violates platform rules or is void for illegality or impossibility.

22. Employment and Work Agreements Between Minors

A minor may work only under conditions allowed by labor law and child protection rules.

A contract between minors involving labor or services must be examined carefully.

Examples:

a minor hires another minor to do school projects;
a minor pays another minor for online editing;
a minor manages a small online shop with another minor;
a minor engages another as a performer;
minors agree to split income from content creation;
a minor recruits another minor for modeling, streaming, or events.

Legal issues may include:

capacity to contract;
child labor laws;
parental consent;
exploitation;
school attendance;
hazardous work;
working hours;
compensation;
intellectual property;
use of image and likeness;
tax and platform rules;
and possible criminal liability if the work involves sexual, exploitative, or harmful content.

A contract involving prohibited child labor or exploitation may be void and may trigger administrative or criminal consequences.

23. Partnership or Business Agreements Between Minors

Minors may attempt to form small businesses together.

Examples:

online selling partnership;
food stall project;
thrift shop;
school merchandise business;
content channel;
gaming team sponsorship;
buy-and-sell group;
event organizing;
digital design service.

A partnership agreement between minors is vulnerable because both lack full capacity. It may be voidable and difficult to enforce.

Issues include:

capital contributions;
profit sharing;
losses;
debts to suppliers;
tax registration;
business permits;
liability to customers;
intellectual property;
use of parents’ accounts;
contracts with adults;
bank or e-wallet accounts;
and ownership of inventory.

Parents or guardians may need to participate for lawful and enforceable business arrangements.

24. Lease Agreements Between Minors

A lease between minors is generally voidable.

Examples:

a minor rents a room from another minor;
a minor leases a parking space from another minor;
a minor allows another minor to use equipment for a fee;
a minor rents a camera, laptop, or costume to another minor.

If the leased property belongs to the parents, the minor may also lack authority to lease it.

If the lease involves real property, the problem is more serious because possession, rent, deposits, damages, and authority are involved.

The true owner or legal representative may seek recovery or annulment.

25. Donation Between Minors

Donation is a special contract governed by strict rules.

A minor generally cannot validly donate property because donation requires capacity to dispose. A minor also may have limited capacity to accept donations, depending on the nature and conditions.

A donation between minors may be invalid or voidable depending on the property, value, acceptance, and legal requirements.

Examples:

a minor gives a phone to another minor;
a minor donates money;
a minor gives inherited property;
a minor gives a valuable collectible.

Small gifts may be tolerated in daily life, but legally significant donations by minors are problematic.

26. Compromise Agreements Between Minors

A compromise is a contract where parties make concessions to avoid or end litigation or dispute.

Minors cannot freely compromise legal claims without proper representation. If a minor’s rights are being compromised, a parent or guardian may need to act, and court approval may be required in some cases.

A settlement between two minors after a dispute, such as property damage or debt, may be challenged if not approved by guardians or court when necessary.

27. Waivers and Quitclaims Signed by Minors

A minor’s waiver of rights is generally suspect.

Examples:

waiver of refund;
waiver of liability for injury;
waiver of ownership claim;
release of debt;
agreement not to sue;
waiver of inheritance;
waiver of compensation;
waiver after an accident;
quitclaim after online scam.

A minor generally cannot validly waive substantial rights without legal capacity and proper representation.

A waiver signed by a minor may be voidable, unenforceable, or void depending on the context.

28. Contracts Involving Inheritance Rights

Minors may inherit property, but contracts involving inheritance rights are sensitive.

A minor cannot freely sell, waive, mortgage, or partition inherited property without proper legal safeguards.

A contract between minors involving future inheritance may be void if it concerns future inheritance not yet vested, because contracts over future inheritance are generally prohibited except in cases allowed by law.

If inheritance has already vested due to death, a minor’s share still requires protection and may need court-approved representation for sale or compromise.

29. Contracts Involving Motor Vehicles

A minor generally cannot validly enter into major motor vehicle transactions without proper authority.

Examples:

a 17-year-old sells a motorcycle to a 16-year-old;
a minor buys a car on installment;
a minor signs a deed of sale for a vehicle;
a minor assumes monthly payments;
minors agree on rental of a motorcycle.

Issues include:

contractual capacity;
driver licensing rules;
registration with the Land Transportation Office;
insurance;
liability for accidents;
parental responsibility;
ownership documents;
payments;
and possible criminal or administrative violations.

A notarized deed of sale does not automatically cure minority.

30. Contracts for School Projects and Student Activities

Minors often make agreements for school-related projects.

Examples:

group contribution agreements;
payment for printing;
rental of costumes;
payment for research materials;
school event ticket sales;
contribution for field activities;
sharing cost of equipment.

These are usually small and informal. Strict litigation is uncommon. But if disputes arise, the amounts may be treated through restitution, unjust enrichment, or parental involvement rather than ordinary contract enforcement.

If the expense is educational and necessary, the rule on necessaries or support may become relevant.

31. Contracts Involving Marriage

In the Philippines, persons below eighteen cannot validly marry. A marriage involving a party below eighteen is void.

Contracts between minors connected to marriage, dowry-like arrangements, cohabitation, or sexual consideration may be void or contrary to law and public policy.

If a contract involves sexual exploitation, trafficking, abuse, or coercion of a minor, criminal law and child protection laws may apply.

32. Contracts for Sexual or Exploitative Acts

Any contract involving sexual exploitation of a minor is void and may be criminal.

Examples include:

payment for sexual acts;
explicit content involving minors;
live streaming sexual content;
grooming arrangements;
prostitution;
trafficking;
compensated dating involving minors;
online exploitation;
exchange of intimate photos;
blackmail or sextortion.

Minority does not simply make these contracts voidable. They are void, illegal, and may trigger serious criminal liability for adults or, in appropriate cases, intervention under juvenile justice laws if minors are involved.

33. Contracts Involving Alcohol, Tobacco, Vapes, or Regulated Goods

Contracts between minors involving prohibited or age-restricted goods may be void or illegal.

Examples:

sale of alcohol to minors;
sale of cigarettes or vape products;
sale of dangerous drugs;
sale of weapons;
sale of fireworks in prohibited circumstances;
sale of prescription medicines without authority;
sale of obscene materials;
sale of stolen property.

The issue is not just minority. The object may be illegal or regulated, making the transaction void and possibly punishable.

34. Contracts for Illegal Acts

A contract between minors to commit an illegal act is void.

Examples:

agreement to steal;
agreement to hack accounts;
agreement to commit fraud;
agreement to sell stolen phones;
agreement to cheat in exams for payment;
agreement to create fake IDs;
agreement to distribute illegal drugs;
agreement to bully or harm another person;
agreement to vandalize property;
agreement to threaten or extort.

No court will enforce such a contract. Criminal, administrative, school disciplinary, or juvenile justice consequences may arise.

35. Misrepresentation of Age by a Minor

What if a minor lies and says he or she is eighteen?

Under Philippine law, the doctrine of estoppel against minors is applied cautiously because the law protects minors. Generally, a minor is not easily estopped from invoking minority, especially where the other party failed to verify age or where enforcing the contract would defeat protective policy.

However, fraudulent misrepresentation may have consequences.

Possible effects:

the minor may still be able to annul the contract;
restitution may be required to the extent benefited;
the minor may be liable for fraud in appropriate civil contexts;
parents may become involved;
criminal liability may arise in extreme cases involving falsification or scams, subject to juvenile justice rules;
the adult or other party may recover property if still available;
courts may prevent unjust enrichment.

When both parties are minors, misrepresentation of age by one minor may not eliminate the other minor’s incapacity.

36. Estoppel and Minors

Estoppel prevents a person from taking a position inconsistent with prior conduct if another relied on it.

But estoppel against minors is limited. The law generally prefers protecting minors over enforcing contracts based on their immature conduct.

Still, courts may consider fairness when a minor:

actively deceived the other party;
retained benefits;
caused loss;
misrepresented age using false documents;
resold property;
or acted in bad faith.

The remedy may be restitution or recovery of property rather than full enforcement of the voidable contract.

37. Fraud Committed by a Minor

A minor may commit fraud in fact, even if the minor lacks contractual capacity.

Example:

A 17-year-old sells a phone online, receives payment, and never delivers. The buyer is also 17.

Legal consequences may include:

parental involvement;
civil restitution;
school or barangay intervention;
action through guardians;
complaint for fraud or estafa if elements are present, subject to juvenile justice rules;
recovery of money or property;
platform account suspension;
and possible court proceedings through legal representatives.

Minority protects against contractual incapacity, but it does not give a minor a license to scam others.

38. Property Damage Between Minors

Sometimes a contract between minors involves borrowing or renting an item, then the item is damaged.

Example:

A 16-year-old borrows a camera from a 17-year-old for a fee and damages it.

The owner may seek compensation. Because both are minors, the claim may involve:

voidable contract principles;
quasi-delict;
parental responsibility;
restitution;
negligence;
custody and supervision;
barangay or school mediation;
and possible insurance.

Parents may be liable in certain cases for damages caused by minors living with them, subject to legal requirements.

39. Tort or Quasi-Delict Is Separate From Contract

Even if a contract is voidable, a minor may still be involved in liability for wrongful acts under principles outside contract.

Examples:

damaging borrowed property;
injuring another person;
stealing an item;
defaming another online;
causing a motorcycle accident;
destroying rented equipment;
hacking an account;
misappropriating money.

The claim may be based not only on contract but also on quasi-delict, unjust enrichment, property recovery, or criminal law.

Parental responsibility may become relevant.

40. Parental Responsibility for Minors’ Acts

Parents may be responsible for damages caused by minor children under certain circumstances, especially when the child lives with them and parental supervision is legally relevant.

This is separate from contract validity.

Example:

A minor rents a bicycle from another minor and destroys it through negligence. The owner’s parents may pursue the responsible minor’s parents for damages, depending on the facts.

This does not mean parents are automatically liable for every contract signed by a minor. Liability for damages caused by wrongful acts is different from liability for contractual promises.

41. Effect of Full Performance

What if both minors fully performed the contract and neither complains until much later?

A voidable contract remains valid until annulled. If fully performed, the practical result may remain undisturbed unless one party timely seeks annulment.

Example:

A 17-year-old sells a used book to a 16-year-old for ₱300. The buyer gets the book, the seller gets the money, and both are satisfied. The law will not usually interfere unless a dispute is raised.

For ordinary daily transactions, practical finality often prevails unless there is fraud, exploitation, illegality, or substantial prejudice.

42. When the Minor Reaches Eighteen

Once a minor reaches eighteen, the person may:

ratify the contract;
disaffirm or seek annulment within the legal period;
continue performance;
demand performance;
return what was received;
negotiate settlement;
or file an action if necessary.

If the person continues to accept benefits after reaching majority, this may be treated as implied ratification.

Example:

A 17-year-old entered a business agreement. After turning 18, he continues operating under the same agreement, accepting profits and making decisions. He may be deemed to have ratified it.

43. Prescription of Action for Annulment

An action for annulment based on minority must be brought within the period provided by law. Generally, the period is counted from the time the minor reaches majority.

A person who waits too long after turning eighteen may lose the right to annul.

Because prescription rules can be technical, parties should act promptly once the issue arises.

44. Ratification by Silence or Inaction

Mere silence does not always amount to ratification. But silence combined with continued enjoyment of benefits, failure to object after reaching majority, continued payments, or performance may amount to implied ratification.

Example:

A minor bought a laptop on installment at 17. After turning 18, he keeps the laptop and continues paying for several months. This may support ratification.

If the former minor wants to annul, he or she should act promptly and avoid conduct inconsistent with annulment.

45. Restitution When the Object Is Lost

If the contract is annulled but the object is lost, the court must determine responsibility.

Issues include:

who had possession;
whether the loss was due to fault;
whether the minor benefited;
whether the object was consumed;
whether it was resold;
whether it was destroyed by accident;
whether parents or guardians were involved;
whether the other party was also a minor;
whether bad faith existed.

A minor may not always be required to return full value if not benefited, but bad faith or wrongful conduct may affect the outcome.

46. Restitution When Money Has Been Spent

If a minor received money under a voidable contract and spent it, the minor’s duty to return may be limited to the extent benefited.

Example:

A minor sells a gadget, receives ₱20,000, and spends the money. If the sale is annulled, must the minor return ₱20,000?

The answer depends on whether the minor still has the benefit, what the money was used for, whether the buyer returns the gadget, whether fraud occurred, and whether equity requires reimbursement.

If the money was spent on necessaries, the minor may be considered benefited. If squandered, the result may still be protective but not necessarily favorable if fraud or bad faith is present.

47. Unjust Enrichment

Even when a contract is defective, the law may prevent unjust enrichment.

Unjust enrichment means one person should not unfairly benefit at another’s expense without legal basis.

In minor contracts, courts try to balance:

protecting minors from their lack of capacity;
preventing minors from using incapacity as a tool for fraud;
restoring property where possible;
reimbursing necessaries;
and preventing one side from keeping both the money and the goods.

Unjust enrichment does not always lead to full contract enforcement, but it may support restitution.

48. Formalities Do Not Cure Incapacity

A contract does not become valid simply because it is:

written;
notarized;
witnessed;
signed in front of adults;
accompanied by a video recording;
made through chat;
supported by receipts;
paid through bank transfer;
delivered by courier;
acknowledged by parents informally;
or posted online.

If a party is a minor, capacity remains an issue.

Notarization may make a document public and prove execution, but it does not give a minor legal capacity.

49. Effect of Parental Consent

Parental consent may matter but is not a universal cure.

For ordinary low-value transactions, parental approval may make the arrangement practically acceptable.

For major transactions involving significant property, debt, real estate, compromise, or disposition of the minor’s property, parental consent alone may not be enough. Court approval or guardianship authority may be needed.

If both minors’ parents approved a small sale, the likelihood of dispute may be reduced. But if one minor later challenges the transaction, the court will still examine capacity, authority, and benefit.

50. Guardian’s Role

A legal guardian may represent a minor in property matters, subject to court supervision where required.

A guardian may:

sue on behalf of the minor;
defend the minor;
recover property;
manage assets;
seek court approval for transactions;
compromise claims with authority;
and protect the minor’s interest.

Contracts involving significant assets of minors should involve proper guardianship processes.

51. Contracts Through Agents

A minor generally cannot appoint an agent in a way that exceeds the minor’s capacity. If a minor lacks capacity to enter into a contract directly, the minor usually cannot do indirectly through an agent what the minor cannot do directly.

Likewise, a minor acting as agent for another may raise questions, though agency is primarily based on representation and authority.

If a minor claims to represent a parent, business, or another person, the other party should verify authority.

52. Contracts by Minors With Emancipation Issues

Historically, emancipation affected minors’ capacity in some legal contexts. Under current practical rules after the lowering of age of majority to eighteen, persons below eighteen remain minors even if mature, working, or financially independent.

A 17-year-old who earns income, supports family, or runs a small business is still legally a minor.

Financial independence does not automatically create full contractual capacity.

53. Marriage Does Not Make a Person Below Eighteen Fully Capable

Because persons below eighteen cannot validly marry under current Philippine law, marriage cannot ordinarily be used as a basis to treat a person under eighteen as fully capacitated.

Any supposed marriage involving a person below eighteen raises separate validity issues.

54. Minors and Bank Accounts

Some minors may have bank accounts or e-wallet accounts, often with parental consent or special arrangements. Having an account does not mean full contractual capacity for all transactions.

A minor may be allowed to deposit, withdraw, or transact under bank rules, but contracts beyond the permitted scope may still be voidable or require guardian participation.

55. Minors and Credit

Minors generally cannot validly bind themselves to credit arrangements like adults.

Examples:

credit card debt;
installment purchase;
personal loan;
buy-now-pay-later scheme;
pawn transaction;
financing agreement;
postpaid plan;
subscription lock-in;
loan app borrowing.

If a minor signs such an agreement, enforceability may be challenged. The provider may need to rely on a parent, guardian, co-maker, or adult account holder.

If the minor misrepresented age, other issues may arise, but minority remains significant.

56. Subscription Contracts and App Terms

Minors often agree to app terms, online subscriptions, games, streaming services, and platform rules.

These agreements may include:

subscription payments;
automatic renewal;
in-app purchases;
penalties;
account bans;
arbitration clauses;
data use consent;
content licenses;
creator monetization;
marketplace selling.

Platforms often require parental consent for minors. If a minor contracts without required consent, the platform may suspend, refund, refuse service, or rely on terms limiting rights.

Philippine contract law principles on minority may still apply, but cross-border platform terms can complicate enforcement.

57. School Rules and Contracts

Schools often require parents or guardians to sign enrollment contracts, consent forms, waivers, and payment undertakings because students may be minors.

A minor student’s signature alone may not be enough for obligations like tuition payment, liability waivers, field trip consent, or disciplinary undertakings.

For student-to-student agreements, school rules may provide mediation or discipline separate from civil contract law.

58. Medical Consent and Minors

Medical agreements involving minors generally require parental or guardian consent, except in emergencies or specific legally recognized situations.

A contract between minors for payment of medical expenses may be secondary to the legal obligation of parents or guardians to provide support.

If a minor pays for another minor’s emergency needs, reimbursement may be sought depending on circumstances, but the proper obligors may include the benefited minor’s parents or estate if death occurs.

59. Intellectual Property Contracts Between Minors

Minors may create art, music, videos, software, designs, and written works. Contracts involving intellectual property may include:

sale of artwork;
commission agreement;
license to use music;
content collaboration;
assignment of copyright;
revenue-sharing agreement;
management agreement;
sponsorship;
brand endorsement;
release of image and likeness.

Because minors lack full capacity, such contracts should involve parents or guardians. Major assignments or long-term contracts may require additional safeguards.

A minor’s creative work may have value, but the minor’s ability to alienate rights is limited.

60. Talent, Modeling, and Entertainment Contracts

Contracts involving minors in entertainment, modeling, streaming, sports, or social media require careful handling.

Issues include:

parental consent;
child labor rules;
working hours;
education;
safety;
compensation;
trust or savings arrangements;
image rights;
exclusivity;
morality clauses;
termination;
exploitation;
data privacy;
and regulatory compliance.

A contract between minors in this area is vulnerable and may be voidable or void if exploitative or contrary to child protection laws.

61. Sports Agreements Between Minors

Minors may make agreements for teams, sponsorships, prize-sharing, equipment, coaching, or competitions.

Legal issues include:

capacity;
parental consent;
school rules;
sports association rules;
waiver of injury liability;
prize money;
travel consent;
insurance;
endorsement rights;
and training obligations.

A minor cannot freely waive injury claims or bind himself or herself to long-term obligations without proper representation.

62. Data Privacy Consent by Minors

Contracts involving personal data of minors require special care. Consent for processing a minor’s data may need parent or guardian involvement depending on the context.

Examples:

online platform registration;
school project apps;
photo release;
influencer agreement;
medical data sharing;
contests;
customer records;
marketplace accounts.

A minor’s consent may not always be sufficient for lawful data processing.

63. Settlement of Online Scams Between Minors

If a minor scams another minor online, the families often try to settle.

A written settlement should ideally involve parents or guardians and should state:

amount to be returned;
item to be returned;
deadline;
acknowledgment of receipt;
no harassment agreement;
school or barangay involvement, if any;
reservation or waiver of claims;
and signatures of parents or guardians.

If the amount is significant, legal advice is advisable.

A settlement signed only by minors may itself be voidable.

64. Barangay Conciliation

Disputes between minors may be brought informally before barangay officials, especially if families live in the same locality.

However, barangay settlement involving minors should involve parents or guardians. Barangay officials should avoid forcing minors to assume obligations beyond their legal capacity.

A barangay settlement may help resolve small disputes, but significant property, injury, or criminal issues may require proper legal procedures.

65. Court Action Involving Minors

A minor generally sues or is sued through a parent, guardian, guardian ad litem, or legal representative.

If both parties are minors, their legal representatives must appear for them.

The court may appoint a guardian ad litem if needed to protect the minor’s interest.

Proceedings must consider the welfare of the minors and the protective purpose of the law.

66. Small Claims and Minors

Small claims cases may involve debts or money claims. If a party is a minor, representation becomes important.

A minor cannot simply litigate as an ordinary adult. The parent or guardian may need to appear or act on the minor’s behalf.

If the claim is based on a voidable contract between minors, the court must consider capacity, restitution, and whether the amount claimed is legally recoverable.

67. Criminal or Juvenile Justice Issues

If the transaction involves fraud, theft, estafa, cybercrime, threats, coercion, extortion, falsification, or exploitation, criminal law may arise.

When the alleged offender is a minor, juvenile justice rules apply. The response may involve:

determination of age;
discernment;
diversion;
intervention programs;
social welfare involvement;
parental participation;
restorative justice;
and, for serious cases, court proceedings.

Civil contract rules do not shield a minor from all consequences of wrongful acts.

68. Civil Liability Arising From a Minor’s Crime

Even when juvenile justice rules affect criminal responsibility, civil liability may still arise.

If a minor obtains money or property through fraud or theft, the victim may seek restitution.

Parents may also have responsibility depending on law and facts.

Thus, a minor cannot simply say, “I am underage, so I can keep the money.”

69. School Discipline

Contracts or disputes between minors may also violate school rules.

Examples:

selling prohibited items on campus;
unauthorized fundraising;
gambling;
lending with interest;
cheating services;
selling exam answers;
cyberbullying for payment;
damaging school property;
unauthorized ticket sales.

The school may impose disciplinary measures separate from civil or criminal remedies.

70. Effect of Illegal Object

If the object of the contract is illegal, the contract is void.

Examples:

sale of stolen property;
sale of illegal drugs;
sale of fake IDs;
sale of exam answers;
sale of explicit images of minors;
hacking services;
agreement to physically harm someone;
illegal gambling transaction;
prohibited weapons transaction.

When both parties are minors, the law may also involve child protection, juvenile justice, school discipline, and parental responsibility.

No party can ask a court to enforce an illegal contract.

71. Effect of Immoral Cause

A contract with immoral cause is void.

Examples:

payment for sexual acts;
payment for humiliating another person;
agreement to spread intimate images;
agreement to bully someone;
agreement to conceal abuse;
agreement involving exploitation.

Such agreements have no enforceable legal effect and may expose the parties or involved adults to serious liability.

72. Minors and Agency of Necessity

In emergencies, a minor may act in ways that create obligations based on necessity, not ordinary contractual capacity.

Example:

A 17-year-old brings a 15-year-old injured friend to a clinic and promises to pay for basic emergency treatment. The clinic provides necessary care.

The law may recognize recovery for reasonable necessary expenses, but the final obligation may involve parents, guardians, or the benefited minor’s estate if applicable.

73. Contracts for Food, Transportation, and Daily Needs

Minors commonly buy food, commute, buy school supplies, pay for printing, and make daily transactions.

These are usually treated as ordinary transactions necessary for daily life. Vendors and service providers do not usually need formal parental consent for every small transaction.

However, for larger transactions, luxury purchases, high-value goods, installment obligations, or long-term commitments, minority becomes a serious issue.

74. High-Value Luxury Purchases by Minors

If a minor buys expensive luxury items, the contract may be annulled.

Examples:

expensive jewelry;
high-end phone;
designer bag;
motorcycle;
gaming computer;
collectible watch;
expensive pet;
camera equipment;
concert package;
travel package.

The seller risks non-enforcement if the minor or parents later challenge the transaction.

A prudent seller should verify age and require parent or guardian consent for significant transactions.

75. Pawn or Sale of Family Property by Minor

A minor who sells or pawns family property may lack ownership and authority.

Example:

A 16-year-old sells his parent’s phone or jewelry to another minor.

The buyer may not acquire good title if the seller had no right to sell. The true owner may recover the property. The buyer may seek refund from the seller, but enforcement may be complicated by minority.

If theft or misappropriation occurred, criminal or juvenile justice issues may arise.

76. Sale of Stolen Property Between Minors

A buyer of stolen property generally does not acquire valid ownership, even if the buyer is also a minor.

The owner may recover the property. The buyer may seek return of money from the seller, subject to legal limitations.

If the buyer knew or should have known the property was stolen, the buyer may also face legal consequences.

77. Contracts Involving Pets

Minors may buy, sell, or adopt pets. Issues may include:

capacity;
animal welfare laws;
parental consent;
ownership;
vaccination;
neglect;
return or refund;
disease or defects;
responsibility for injuries caused by the pet;
local ordinances;
and cruelty or abandonment.

A significant pet purchase or breeding agreement between minors may be voidable and may require parental involvement.

78. Contracts Involving Installment Payments

Installment agreements create continuing obligations. Minors generally cannot bind themselves to long-term payment commitments.

Examples:

gadget installments;
motorcycle installment;
furniture installment;
online purchase installment;
monthly subscription;
rent-to-own arrangements.

If a seller knowingly contracts with a minor, the seller risks annulment or inability to collect future payments.

A seller should require a parent or legal guardian as the contracting party.

79. Contracts Involving Penalties

Penalty clauses against minors are difficult to enforce.

Examples:

late payment penalty;
cancellation fee;
forfeiture clause;
liquidated damages;
replacement cost;
penalty for backing out;
non-refundable reservation fee.

A penalty may be unenforceable or reducible if the contract is voidable, if the penalty is unconscionable, or if the minor lacked capacity.

80. Reservation Fees Paid by Minors

A minor may pay a reservation fee for goods, events, services, or property.

If the transaction is voidable, a non-refundable clause may be challenged. The seller may keep only reasonable expenses or may need to return the amount depending on the facts.

For high-value transactions, accepting reservation fees from minors is risky.

81. Contracts of Guaranty or Suretyship by Minors

A minor cannot generally bind himself or herself as guarantor or surety.

A guaranty or suretyship creates serious legal liability, often for another person’s debt. A minor’s undertaking to guarantee another’s obligation is vulnerable to annulment.

Example:

A 17-year-old signs as guarantor for a friend’s debt. The guaranty may be voidable due to minority.

82. Arbitration Clauses and Minors

Contracts may include arbitration clauses. If the contract was entered into by a minor, the arbitration clause may also be affected by incapacity.

A minor may challenge the enforceability of the arbitration agreement. Parental or guardian consent may be required for meaningful enforcement.

In practice, disputes involving minors often require court or guardian involvement rather than private arbitration alone.

83. Choice of Law and Foreign Platforms

Online contracts may involve foreign platforms with terms choosing foreign law. But if the minor is in the Philippines and the dispute is litigated locally, Philippine public policy protecting minors may be relevant.

Foreign terms cannot easily override mandatory Philippine protections for minors.

84. Tax Issues

Minors may earn money from sales, online work, or business. Tax obligations may still arise depending on income and activity, but contractual capacity remains separate.

A minor who earns income may need parental assistance or guardian representation in registrations, filings, and financial compliance.

A contract is not made fully valid just because income was reported or taxed.

85. Practical Rules for Adults Dealing With Minors

Adults should be careful when contracting with minors. Even though this article focuses on contracts between minors, the same capacity issue affects adult-minor transactions.

Practical safeguards:

verify age;
require government ID where appropriate;
require parent or guardian consent;
avoid high-value transactions directly with minors;
avoid lending money to minors;
avoid installment sales to minors;
avoid buying property from minors without proof of ownership and authority;
do not accept waivers from minors;
do not transact in prohibited goods;
document parental approval;
use the parent or guardian as the contracting party;
obtain court approval where required for minor’s property;
and avoid exploitative arrangements.

86. Practical Rules for Minors

Minors should understand that signing or agreeing online may create problems even if the contract is voidable.

A minor should:

ask a parent or guardian before major transactions;
avoid borrowing money;
avoid selling property that belongs to parents;
avoid signing promissory notes;
avoid online account sales;
avoid contracts involving illegal or prohibited items;
avoid giving personal information;
keep receipts and screenshots;
return money or property if a transaction is disputed;
avoid threatening or harassing the other party;
and seek adult help early.

Minority is protection, not permission to deceive others.

87. Practical Rules for Parents

Parents should monitor minors’ transactions, especially online.

Parents may need to:

recover property;
return money if the child was unjustly enriched;
settle disputes;
coordinate with other parents;
report scams;
preserve evidence;
review e-wallet activity;
cancel unauthorized subscriptions;
contact platforms;
seek barangay or school mediation;
prevent further transactions;
and obtain legal advice for serious matters.

Parents should avoid automatically ratifying a transaction by making partial payments or written promises unless they intend to assume responsibility.

88. Evidence in Disputes Between Minors

Useful evidence includes:

written agreement;
screenshots;
chat logs;
payment receipts;
delivery proof;
photos of item;
videos;
e-wallet transaction records;
bank transfer slips;
courier tracking;
witness statements;
school records;
proof of age;
parent or guardian messages;
barangay settlement;
platform terms;
item serial numbers;
police report, if any;
and proof of ownership.

Evidence helps determine whether property should be returned, money refunded, or parents involved.

89. Remedies When a Minor Wants to Cancel the Contract

The minor or representative may:

notify the other party in writing;
offer return of what was received, if still available;
demand return of money or property;
involve parents or guardians;
seek barangay or school mediation;
file a complaint through legal representative if needed;
seek annulment in court for significant contracts;
report fraud or theft if present;
request platform intervention for online transactions;
preserve evidence.

The correct remedy depends on value, urgency, and whether the object is still available.

90. Remedies When the Other Minor Refuses to Return Money or Property

The injured party’s parent or guardian may:

send a written demand;
ask the other minor’s parents to intervene;
seek barangay mediation;
report to school if school-related;
file a civil action through proper representative;
file a complaint for recovery of property;
consider small claims if proper and representation is allowed;
file criminal or cybercrime complaint if fraud, theft, or hacking occurred, subject to juvenile justice rules;
seek help from the platform or payment provider.

For small disputes, practical settlement is usually better than litigation.

91. Demand Letter Between Families

A demand letter should be polite, factual, and clear.

Subject: Request for Return of Money / Property

Dear [Parent/Guardian Name]:

We write regarding the transaction between our child, [Name], and your child, [Name], involving [describe item or money] on [date].

Our child paid/delivered [amount/item], but [state problem: item was not delivered, money was not returned, item was defective, property belongs to us, contract is being cancelled due to minority].

Because both children are minors, we request that the matter be resolved through their parents or guardians. We respectfully demand the return of [money/property] within [number] days from receipt of this letter.

We are willing to discuss an orderly return or settlement. This letter is sent without waiver of our rights and remedies under law.

Sincerely,

[Name] [Parent/Guardian of Minor]

92. Sample Notice of Disaffirmance After Reaching Majority

A former minor who wants to annul or disaffirm may write:

Subject: Notice of Disaffirmance of Contract Entered Into During Minority

Dear [Name]:

I refer to the agreement dated [date] concerning [describe contract]. At the time of the agreement, I was below eighteen years old and therefore lacked full legal capacity to enter into the contract.

I hereby give notice that I do not ratify the agreement and am disaffirming it on the ground of minority. I am prepared to return [item/benefit], subject to the return of [money/property] that I delivered under the agreement.

Please coordinate with me regarding the orderly restoration of what each party received.

Sincerely,

[Name]

93. Sample Ratification After Reaching Majority

If the former minor wants to confirm the contract:

Subject: Ratification of Agreement

Dear [Name]:

I refer to our agreement dated [date] concerning [describe contract]. I entered into the agreement when I was below eighteen years old. I have since reached the age of majority.

After reviewing the agreement, I confirm and ratify it and intend to be bound by its terms from this point forward, subject to any agreed modifications stated in writing.

Sincerely,

[Name]

94. Drafting a Safer Agreement Involving a Minor

If a transaction involving a minor is unavoidable, the safer approach is:

make the parent or guardian the contracting party;
identify the minor only as beneficiary or user;
attach proof of parental authority;
specify the object and price;
avoid oppressive penalties;
include refund rules;
include delivery and return obligations;
require receipts;
avoid illegal or age-restricted goods;
obtain court approval if significant property of the minor is involved;
and keep copies.

For high-value transactions, legal advice is strongly recommended.

95. Common Misconceptions

“A minor’s contract is always void.”

Not always. It is usually voidable, unless another reason makes it void.

“If both are minors, the contract is valid because they are equal.”

No. Both may lack capacity, so either may challenge the contract.

“A notarized contract with a minor is valid.”

Notarization does not cure minority.

“A minor who lies about age can never invoke minority.”

Not necessarily. Estoppel against minors is limited, though fraud may have consequences.

“Parents are automatically liable for every contract signed by their child.”

No. Parents may be liable in certain cases, but not automatically for every contract.

“A minor can keep the benefits because the contract is voidable.”

Not necessarily. Restitution, unjust enrichment, necessaries, fraud, or parental responsibility may apply.

“Online agreements are different.”

No. Online contracts are still subject to capacity rules.

“Once the minor turns eighteen, the contract automatically becomes valid.”

Not automatically. The former minor may ratify or disaffirm, subject to legal periods and conduct.

96. Frequently Asked Questions

Is a contract between two minors valid?

It is generally voidable, not automatically void. Either minor may be able to annul it, subject to law.

Can one minor sue another minor for breach of contract?

A minor generally acts through a parent, guardian, or legal representative. The contract may be challenged due to minority.

Can a minor be forced to pay a debt to another minor?

Possibly, but the agreement is voidable. Recovery may depend on whether the minor was benefited, whether the money was for necessaries, and whether there was fraud or unjust enrichment.

Can a minor sell a phone to another minor?

The sale is generally voidable. If disputed, the parties may need to return the phone and money, subject to circumstances.

Can a minor sell land?

A minor cannot freely sell land. Proper legal representation and possibly court approval are required.

What happens if the item is already lost?

The court or parties must determine fault, benefit, restitution, and fairness. A minor may not always be liable for full value unless benefited or at fault.

Can parents cancel a contract their child entered into?

Parents or guardians may act to protect the minor’s rights and seek annulment or return of property, depending on facts.

Can the minor ratify the contract after turning eighteen?

Yes. Ratification may be express or implied.

Can a minor’s contract be enforced if it involved food, medicine, or school needs?

Contracts for necessaries may support recovery of reasonable value.

Is a contract involving illegal acts between minors enforceable?

No. Illegal contracts are void and may lead to criminal, juvenile, school, or parental consequences.

97. Bottom Line

Under Philippine law, contracts between minors are generally voidable, not automatically void. Since minors lack full legal capacity to give consent, either minor may be able to challenge the contract, usually through a parent, guardian, or upon reaching majority.

The key principles are:

A person below eighteen is a minor.
A minor generally lacks full contractual capacity.
A contract entered into by a minor is usually voidable.
If both parties are minors, both may have the right to annul.
The contract may be ratified after reaching majority.
Restitution may be required if the contract is annulled.
A minor may be liable for necessaries to the extent of reasonable value.
Illegal, immoral, or prohibited contracts are void, not merely voidable.
Notarization, screenshots, or online agreement do not cure lack of capacity.
Parents or guardians should be involved in significant transactions.
Courts will balance protection of minors with prevention of fraud and unjust enrichment.

In practical terms, minor-to-minor contracts may work for ordinary small daily transactions, but they are legally unstable when the transaction involves substantial money, valuable property, installment obligations, waivers, loans, business arrangements, real property, digital assets, or anything illegal or exploitative.

The safest rule is simple: for any important transaction involving a minor, involve the parent or legal guardian, document the transaction properly, and avoid relying on the minor’s signature alone.
