I. Introduction

In the Philippines, many couples live together, acquire property together, raise children together, and conduct themselves in many ways like married spouses without having gone through a valid marriage. These relationships are often called “live-in” relationships, “common-law” relationships, or cohabitation.

Philippine law does not treat unmarried partners exactly the same as married spouses. There is no Philippine “common-law marriage” that automatically makes long-term cohabitants legally married by the mere passage of time. However, the law does recognize property consequences when a man and a woman live together as husband and wife without a valid marriage. These property consequences are primarily governed by Articles 147 and 148 of the Family Code.

The central question is this: when unmarried partners acquire property during their relationship, who owns it?

The answer depends on the legal status of the parties, whether they were capacitated to marry each other, whether there was an impediment to marriage, whether the property was acquired through joint efforts or actual contributions, and whether the parties can prove the source of funds or labor used to acquire the property.

This article discusses the property rights of unmarried partners in the Philippines, including ownership rules, presumptions, donations, inheritance, separation, death, children, debts, remedies, and practical documentation.

II. No Common-Law Marriage in the Philippines

A common misconception is that a couple becomes “common-law married” after living together for a certain number of years. That is not the rule in the Philippines.

A man and woman who live together for five, ten, twenty, or more years do not become legally married merely because of cohabitation. Marriage in the Philippines requires compliance with legal formalities, including the essential and formal requisites of marriage. Without a valid marriage, the parties do not become spouses.

This matters because married spouses may be governed by property regimes such as absolute community of property, conjugal partnership of gains, or complete separation of property. Unmarried partners are not governed by those regimes. Instead, their property rights are governed by the special rules on cohabitation under the Family Code, particularly Articles 147 and 148, and, where applicable, by ordinary rules on co-ownership, contracts, trusts, succession, and donations.

III. The Two Main Legal Categories: Article 147 and Article 148

Philippine law divides unmarried cohabiting partners into two broad categories.

The first category is covered by Article 147 of the Family Code. This applies when a man and a woman live together as husband and wife, are not validly married to each other, but are otherwise capacitated to marry each other.

The second category is covered by Article 148 of the Family Code. This applies when the parties live together but do not fall under Article 147, usually because there is a legal impediment to their marriage, such as an existing valid marriage to another person, an adulterous or concubinage-type relationship, a bigamous relationship, or another situation where the parties could not validly marry each other.

The distinction is critical. Article 147 is more generous. Article 148 is stricter.

IV. Article 147: Partners Capacitated to Marry Each Other

A. When Article 147 Applies

Article 147 applies when the following elements are generally present:

A man and a woman live together as husband and wife;
They are not validly married to each other;
They are capacitated to marry each other;
Their cohabitation is not adulterous, bigamous, or otherwise legally impeded in a way that places them under Article 148.

Common examples include:

A single man and a single woman living together without marrying;
A couple whose marriage is void, but who were otherwise capacitated to marry each other;
A couple who believed they were married but whose marriage was void because of a defect, depending on the surrounding circumstances.

The essence of Article 147 is that the parties could have validly married each other, but for one reason or another, there is no valid marriage.

B. Equal Ownership of Wages and Salaries

Under Article 147, the wages and salaries of the parties are owned by them in equal shares.

This is a significant rule. It means that even if only one partner earns a salary and the other partner stays home to care for the household, the law may still treat the earnings during the cohabitation as belonging equally to both.

The law recognizes that family life involves more than direct cash contribution. Domestic labor, childcare, and household management are treated as valuable contributions.

C. Property Acquired Through Work or Industry

Property acquired by both parties through their work or industry is governed by co-ownership. In the absence of proof to the contrary, their shares are presumed equal.

For example, if an unmarried couple covered by Article 147 buys a house during their cohabitation using earnings from employment or a joint business, the property may be presumed to belong to both in equal shares, even if the title is in the name of only one partner.

The name appearing on the certificate of title is important evidence, but it is not always conclusive between the parties. If the property was acquired during the cohabitation through joint efforts or common funds, the other partner may assert co-ownership.

D. Care and Maintenance of the Family as Contribution

Article 147 expressly recognizes that care and maintenance of the family and household are contributions to the acquisition of property.

This is especially important where one partner earns income while the other performs unpaid domestic work. A homemaker may still be considered to have contributed to the acquisition of property because household work enables the earning partner to work, save, invest, and acquire assets.

Therefore, contribution is not limited to money. It may include industry, labor, domestic services, and family care.

E. Presumption of Joint Ownership

Property acquired while the parties live together under Article 147 is generally presumed to have been obtained by their joint efforts, work, or industry and is therefore presumed to be owned by them equally, unless there is proof that the property was acquired exclusively by one party with his or her own separate funds.

For example, if a parcel of land is bought during the cohabitation, and the funds used came from income earned during the relationship, it may be considered co-owned. But if one partner can prove that the property was bought using money inherited before the relationship, or funds exclusively owned before cohabitation, the presumption may be defeated.

F. Property Owned Before Cohabitation

Property owned by one partner before the live-in relationship generally remains that partner’s separate property, unless it is later transferred, commingled, improved, or treated in a way that creates co-ownership or reimbursement rights.

For example, if Partner A owned a condominium before the relationship, Partner B does not automatically become co-owner merely by moving in. However, if Partner B later contributes money for major renovations, mortgage payments, or improvements, Partner B may have a possible claim for reimbursement, co-ownership, or unjust enrichment, depending on the evidence.

G. Property Bought in One Partner’s Name

A frequent problem arises when property is bought during cohabitation but registered only in one partner’s name.

Registration in one name does not automatically defeat the other partner’s rights. Under Article 147, the other partner may prove that the property was acquired through joint efforts, common funds, or income earned during the cohabitation. However, the registered title holder has a strong evidentiary position, especially against third persons.

Between the partners, courts may look beyond the title and examine the real source of funds, the timing of acquisition, the nature of the relationship, and the contributions of each party.

H. Separation Under Article 147

When Article 147 partners separate, the co-owned properties must be liquidated. As a general rule, each partner receives his or her share, usually presumed equal unless proven otherwise.

Issues may include:

Which properties were acquired during cohabitation;
Which properties were acquired with separate funds;
Whether one partner should be reimbursed for exclusive payments;
Whether one partner used common funds to buy property in his or her own name;
Whether debts were incurred for the benefit of the family or only for one partner;
Whether properties were sold, concealed, or transferred to defeat the other partner’s rights.

If the parties cannot agree, the proper remedy may include an action for partition, accounting, reconveyance, annulment of fraudulent transfers, or other civil action depending on the facts.

V. Article 148: Partners Not Covered by Article 147

A. When Article 148 Applies

Article 148 applies to cohabiting relationships not covered by Article 147. This usually means the parties are not legally capacitated to marry each other.

Examples include:

One or both partners are already validly married to another person;
The relationship is adulterous or concubinage-like;
The relationship is bigamous;
The parties are within a prohibited degree of relationship;
There is another legal impediment preventing them from validly marrying each other.

Article 148 applies a stricter property rule because the law does not want to give full property effects to relationships that violate existing marital or legal obligations.

B. Only Actual Contributions Count

Under Article 148, only properties acquired through the parties’ actual joint contribution of money, property, or industry are co-owned.

Unlike Article 147, there is no broad presumption that everything acquired during cohabitation belongs equally to both. The claimant must show actual contribution.

This means that a partner who claims a share in property must prove that he or she contributed money, property, or industry toward its acquisition.

C. Shares Are Proportionate to Contributions

Under Article 148, the parties own property in proportion to their respective contributions. If Partner A contributed 70% of the purchase price and Partner B contributed 30%, their ownership shares may follow that proportion.

If the parties contributed but there is no proof of the exact amount or proportion, equal contribution may be presumed, depending on the evidence.

The key is that Article 148 focuses on actual contribution, not merely the existence of the relationship.

D. No Automatic Share for Domestic Services Alone in Some Cases

Article 148 is less generous than Article 147. In Article 147, care and maintenance of the family is expressly considered a contribution. In Article 148, the law requires actual contribution of money, property, or industry.

“Industry” can include labor, effort, or participation in a business or acquisition of property. But a partner relying only on the fact of cohabitation, emotional support, or ordinary household companionship may face difficulty proving co-ownership under Article 148.

The factual question is whether the partner contributed something legally recognizable toward the acquisition of the property.

E. Effect if One Partner Is Validly Married to Another

If one of the parties is validly married to another person, complications arise because that married person may already be subject to a matrimonial property regime with his or her lawful spouse.

Under Article 148, the share of the married cohabiting partner in the co-owned property may accrue to the property regime of the existing valid marriage, depending on the circumstances. This protects the lawful spouse and legitimate family from being prejudiced by the extramarital relationship.

For example, if a married man uses funds from his marriage to acquire property with a live-in partner, the lawful spouse may have a claim. The live-in partner may only claim what he or she can prove to have actually contributed.

F. Bad Faith and Forfeiture

Article 148 also contains rules on forfeiture where bad faith exists. If a party is in bad faith, his or her share may be forfeited in favor of common children or, in default of children, in accordance with the rules provided by law.

Bad faith may involve knowledge of an existing marriage or legal impediment. The specific consequences depend on the facts and applicable legal provisions.

G. Separation Under Article 148

Upon separation, Article 148 partners must prove their respective actual contributions. The liquidation process is usually more evidence-heavy than under Article 147.

A partner may need receipts, bank records, loan documents, remittance slips, contracts, messages, business records, or witness testimony to establish contribution.

Without proof, a claim to property may fail, especially if the property is titled solely in the name of the other partner.

VI. Co-Ownership Principles

Property rights of unmarried partners often operate through the concept of co-ownership.

Co-ownership means that two or more persons own an undivided share in the same property. Each co-owner has a proportionate interest, but no co-owner owns a physically specific portion until partition.

For example, if two partners co-own land equally, each owns a one-half undivided interest in the entire property. One does not automatically own the front half and the other the back half.

A. Rights of a Co-Owner

A co-owner generally has the right to:

Use the property according to its purpose, without prejudicing the rights of the other co-owner;
Share in the benefits or fruits of the property;
Demand accounting from a co-owner who exclusively receives income from the property;
Sell, assign, or mortgage his or her ideal share, subject to legal limits;
Demand partition, unless partition is prohibited by agreement or law.

B. No Co-Owner May Exclude the Other

One co-owner generally cannot exclude the other from the property. If one partner locks out the other from a co-owned house, the excluded partner may have remedies, including an action to recover possession, accounting, or partition.

However, practical complications arise when the property is the family home, when children are involved, or when there are allegations of violence, abuse, or threats. In such cases, protective orders and custody considerations may affect possession.

C. Sale of Co-Owned Property

A co-owner cannot sell the entire property without the consent of the other co-owner. A co-owner may generally sell only his or her undivided share.

If one partner sells the entire property without authority, the sale may be valid only as to that partner’s share, unless the buyer is protected by registration, good faith, or other rules.

Where titled land is involved, buyers typically rely on the certificate of title. This is why unmarried partners should be careful about registration, annotations, agreements, and proof of contribution.

D. Partition

A co-owner may demand partition of the property. Partition may be voluntary or judicial.

If the property can be physically divided, the court may order division. If it cannot be divided without prejudice, it may be sold and the proceeds divided according to the parties’ shares.

Partition is one of the most common remedies after unmarried partners separate.

VII. Titles, Deeds, and Registration

A. Title Is Important but Not Always Conclusive Between Partners

For registered land, the certificate of title is powerful evidence of ownership. If the property is registered only in one partner’s name, that partner is presumed to be the owner as far as the title is concerned.

However, between the partners, the other partner may still prove co-ownership under Article 147 or Article 148. Courts may examine the real source of funds and contributions.

B. Protection of Innocent Third Persons

A third person who buys registered property in good faith may be protected if he or she relied on the title and had no notice of another partner’s claim.

This creates risk for an unmarried partner whose contribution is not reflected on the title. Even if that partner has a valid claim against the registered partner, recovery against an innocent buyer may be difficult.

C. Practical Safeguards

Unmarried partners who acquire real property together should consider:

Placing both names on the deed of sale;
Registering both names on the title;
Stating the percentage shares clearly;
Keeping proof of payment;
Executing a co-ownership agreement;
Avoiding use of vague arrangements based only on trust;
Documenting whether funds came from separate or common sources.

Clear documentation can prevent costly litigation.

VIII. Bank Accounts, Vehicles, Businesses, and Personal Property

A. Bank Accounts

A bank account in one partner’s name is not automatically owned by both. However, if the funds came from common income or joint contributions, the other partner may assert a claim.

Joint bank accounts are generally easier to prove as jointly controlled, but the exact ownership of the funds may still depend on source and intent.

A joint “and/or” account may allow either party to withdraw, but withdrawal authority is not always the same as beneficial ownership. A partner who empties a joint account may still be required to account for funds belonging to the other.

B. Vehicles

The registered owner of a vehicle is presumed to own it. But, as with real property, the other partner may prove contribution to the purchase price, amortization, repairs, or business use.

If a vehicle was bought during an Article 147 cohabitation using common earnings, it may be co-owned even if registered in one partner’s name. Under Article 148, actual contribution must be proven.

C. Businesses

Business interests acquired during cohabitation can be difficult to divide.

Relevant questions include:

Who registered the business?
Who supplied the capital?
Who managed operations?
Were profits reinvested?
Did one partner work without salary?
Were business assets bought with common funds?
Is the business a sole proprietorship, partnership, corporation, or informal enterprise?

If both partners contributed to a business, one may claim co-ownership, partnership rights, reimbursement, accounting, or a share in profits, depending on the structure and evidence.

D. Household Items and Personal Property

Furniture, appliances, jewelry, gadgets, and other movable items may also be disputed. Ownership may depend on receipts, source of payment, possession, intent, gifts, and proof of contribution.

Items personally given as gifts to one partner may belong exclusively to that partner, unless the gift is void or legally prohibited.

IX. Donations Between Unmarried Partners

A. Donations Between Spouses and Common-Law Partners

Philippine law restricts donations between spouses during marriage, except moderate gifts on occasions of family rejoicing. This rule exists to prevent undue influence, fraud against creditors, and circumvention of property rules.

Philippine jurisprudence has applied similar policy considerations to certain donations between common-law partners living together as husband and wife. The reason is that the law should not allow unmarried partners to do indirectly what spouses are prohibited from doing directly, especially where the relationship raises concerns of influence or circumvention.

Therefore, a donation from one live-in partner to another may be vulnerable to challenge, particularly where the donation is substantial.

B. Donations in Adulterous or Illicit Relationships

The Civil Code also prohibits donations between persons who are guilty of adultery or concubinage at the time of the donation. Donations made because of an immoral or illicit relationship may be void.

This rule is especially relevant under Article 148 relationships where one or both parties are already married to someone else.

C. Moderate Gifts

Moderate gifts may be allowed, depending on the occasion, financial condition of the giver, and surrounding facts. Examples may include ordinary birthday gifts, holiday gifts, or customary tokens.

However, transferring land, a condominium, a vehicle, or a large sum of money is unlikely to be considered a mere moderate gift.

D. Sale Disguised as Donation

Sometimes parties execute a deed of sale even though no price was actually paid, intending it as a donation. Such transactions may be attacked as simulated contracts or disguised donations.

If the underlying donation is prohibited, the disguised transaction may also be invalid.

X. Inheritance Rights of Unmarried Partners

A. Unmarried Partners Are Not Compulsory Heirs

An unmarried partner is not a compulsory heir under Philippine succession law. Compulsory heirs generally include legitimate children and descendants, legitimate parents and ascendants, the surviving spouse, and acknowledged illegitimate children, among others depending on the situation.

A live-in partner is not treated as a surviving spouse because there is no valid marriage.

B. No Intestate Share by Mere Cohabitation

If a person dies without a will, the surviving live-in partner generally does not inherit by intestate succession merely because of cohabitation.

This can lead to harsh results. A partner may have lived with the deceased for decades but receive nothing from the estate unless he or she can prove co-ownership, creditor rights, reimbursement rights, or is named in a valid will.

C. Rights Through Co-Ownership

Although an unmarried partner does not inherit as a spouse, he or she may still own part of the property by co-ownership.

For example, if Partner A dies and a house is titled in Partner A’s name but was actually co-owned with Partner B under Article 147, Partner B may first assert ownership of his or her share. Only Partner A’s share forms part of Partner A’s estate.

This distinction is crucial. The surviving partner is not inheriting the co-owned share; the partner is asserting that the share already belonged to him or her.

D. Rights Through a Will

A person may give property to a live-in partner through a will, subject to the legitime of compulsory heirs and other legal restrictions.

If the deceased has compulsory heirs, the will cannot impair their legitime. The live-in partner may receive only the free portion of the estate.

A will in favor of a live-in partner may also be challenged if the relationship falls under prohibited situations, such as adulterous or illicit circumstances, or if the testamentary disposition violates law or public policy.

E. Life Insurance and Beneficiary Designations

A live-in partner may be named as a beneficiary in life insurance or similar arrangements, subject to legal limitations. However, where the designation violates prohibitions on donations or public policy, or prejudices compulsory heirs or creditors, it may be challenged.

The validity of beneficiary designations can depend on the nature of the relationship, insurable interest rules where applicable, and statutory restrictions.

XI. Children of Unmarried Partners

A. Illegitimate Children

Children born to unmarried parents are generally classified as illegitimate, unless the parents later validly marry and the child qualifies for legitimation, or unless another rule applies.

Illegitimate children have rights to support and inheritance from their parents.

B. Support

Both parents are obliged to support their children. Support includes food, shelter, clothing, medical care, education, and other necessities consistent with the family’s resources.

Even if the parents separate, the obligation to support the child remains.

C. Custody

Custody is separate from property ownership. As a general rule, parental authority over an illegitimate child belongs to the mother, although the father may have visitation rights and may be required to provide support.

Property disputes between unmarried partners should not be used to deprive children of support.

D. Children and Forfeited Shares

In certain cases involving bad faith under the Family Code, a party’s share in co-owned property may be forfeited in favor of common children, subject to legal rules. This may arise in relationships falling under Article 148 or void marriage situations.

XII. Debts and Obligations

A. Debts for Family Benefit

Debts incurred for the benefit of the family or common household may be considered in the liquidation of co-owned property. Examples include housing expenses, utilities, food, medical bills, and education expenses for common children.

However, the treatment of debts depends on whether the relationship falls under Article 147 or Article 148 and whether the obligation was truly for the common benefit.

B. Personal Debts

A debt incurred by one partner for personal purposes does not automatically bind the other partner.

For example, gambling debts, personal loans, credit card obligations, or business debts incurred solely by one partner may remain that partner’s responsibility unless the other partner consented, benefited, guaranteed, or otherwise became legally bound.

C. Creditors

Creditors may go after the debtor’s property or share in co-owned property. If property is co-owned, a creditor of one partner may generally reach only that partner’s share, subject to legal procedure.

Where one partner is legally married to another person, creditors and the lawful spouse may raise additional issues involving the matrimonial property regime.

XIII. Improvements on Property Owned by One Partner

A common situation is where one partner owns land or a house before cohabitation, and the other partner later spends money on improvements.

Examples include:

Building a house on land owned by the other partner;
Paying for renovations;
Paying mortgage amortizations;
Constructing rental units;
Funding repairs or expansion.

The contributing partner does not automatically become owner of the land. Land ownership generally follows title. However, the contributing partner may have claims depending on the facts, such as reimbursement, co-ownership of improvements, unjust enrichment, or compensation for necessary and useful expenses.

The outcome depends heavily on evidence, intent, and whether the case falls under Article 147 or Article 148.

XIV. Property Bought Using One Partner’s Separate Funds

Even during cohabitation, a partner may acquire property using separate funds. Examples include:

Money earned before the relationship;
Inheritance;
Proceeds from sale of separate property;
Damages or compensation personal to that partner;
Gifts exclusively given to that partner.

Under Article 147, property acquired during cohabitation is presumed jointly owned, but that presumption may be rebutted by proof that the property was purchased exclusively with separate funds.

Under Article 148, the claimant must prove actual contribution. If the property was bought solely with one partner’s separate money, the other partner generally has no ownership share unless he or she contributed in another legally recognized way.

XV. Overseas Filipino Workers and Remittances

Many disputes involve one partner working abroad while the other stays in the Philippines.

If an OFW partner sends remittances used to buy land, build a house, or operate a business, the question is whether the receiving partner acquired ownership or merely acted as administrator, agent, trustee, or nominee.

Relevant evidence includes:

Remittance records;
Messages describing the purpose of the funds;
Deeds of sale;
Titles;
Bank records;
Receipts;
Construction contracts;
Witnesses;
Whether funds were intended as support, gift, investment, or purchase money.

If the property is placed in the receiving partner’s name, the OFW partner may still assert ownership or reconveyance if he or she can prove that the funds belonged to him or her and were not intended as a donation.

XVI. Foreigners in Live-In Relationships

Foreigners are generally prohibited from owning private land in the Philippines, subject to limited constitutional and statutory exceptions. This creates special problems when a foreigner in a live-in relationship pays for land placed in the Filipino partner’s name.

A foreigner who provides the purchase money for Philippine land cannot generally enforce ownership of the land if doing so would violate the constitutional prohibition. Courts may refuse to aid arrangements intended to circumvent land ownership restrictions.

However, depending on the facts, a foreigner may have limited claims for reimbursement, damages, or protection against fraud, although courts are cautious where the transaction itself is designed to evade the Constitution.

Foreigners may own condominium units subject to statutory limits on foreign ownership, and may own buildings or improvements separate from land in some situations. Each case requires careful structuring.

XVII. Same-Sex Partners

Philippine marriage law currently does not recognize same-sex marriage. The specific wording of Articles 147 and 148 refers to a man and a woman living together as husband and wife. This creates uncertainty for same-sex partners because the Family Code provisions on cohabitation were drafted in heterosexual terms.

Same-sex partners may still rely on ordinary civil law principles, such as co-ownership, contracts, partnership, agency, trust, unjust enrichment, and succession through a will, subject to legal limitations.

Because statutory protection is less explicit, documentation is especially important for same-sex partners. They should consider written co-ownership agreements, wills, powers of attorney, beneficiary designations where valid, and clear records of contribution.

XVIII. Remedies in Property Disputes

When unmarried partners separate or when one partner dies, several remedies may be available.

A. Partition

If property is co-owned, a partner may file an action for partition. The court may divide the property or order its sale and distribute the proceeds according to the parties’ shares.

B. Accounting

If one partner managed, leased, sold, or profited from co-owned property, the other may demand an accounting.

C. Reconveyance

If property was placed in one partner’s name despite being acquired with the other partner’s funds or joint funds, reconveyance may be sought where legally proper.

D. Reimbursement

A partner who paid more than his or her share, funded improvements, or settled common obligations may claim reimbursement.

E. Annulment of Fraudulent Transfers

If one partner transfers property to relatives, friends, or corporations to defeat the other partner’s rights, the transfer may be challenged as fraudulent, simulated, or in bad faith.

F. Injunction

A court may be asked to prevent sale, disposal, concealment, or dissipation of disputed property while the case is pending.

G. Settlement Agreement

The parties may voluntarily settle property issues through a written agreement. Settlement is often faster and less costly than litigation, but it should be carefully drafted and notarized where appropriate.

XIX. Evidence Needed to Prove Property Rights

Property disputes between unmarried partners are often won or lost on evidence.

Important evidence includes:

Deeds of sale;
Certificates of title;
Tax declarations;
Receipts;
Bank statements;
Remittance records;
Loan documents;
Construction contracts;
Mortgage records;
Business permits;
Corporate documents;
Vehicle registration papers;
Text messages and emails;
Photos of construction or business operations;
Witness testimony;
Proof of salary or income;
Proof of inheritance or separate funds;
Written agreements between the partners.

The more informal the relationship, the more important documentation becomes.

XX. Practical Agreements Between Unmarried Partners

Unmarried partners may execute agreements to clarify property ownership. These may include:

Co-ownership agreement;
Property sharing agreement;
Loan agreement;
Acknowledgment of contribution;
Partnership agreement;
Lease agreement;
Agreement on expenses;
Agreement on separation and liquidation;
Waiver or quitclaim, if valid and not contrary to law.

Such agreements must not violate law, morals, public policy, marriage laws, land ownership restrictions, or the rights of lawful spouses, children, creditors, and compulsory heirs.

A well-drafted agreement should identify the property, source of funds, percentage ownership, responsibility for taxes and expenses, possession, sale conditions, dispute resolution, and what happens upon separation or death.

XXI. Common Misconceptions

1. “We lived together for years, so we are automatically married.”

False. Cohabitation does not create a valid marriage in the Philippines.

2. “The property is in my name, so my partner has no rights.”

Not necessarily. If the property was acquired during cohabitation through joint efforts or common funds, the other partner may have a claim, especially under Article 147.

3. “I did not earn money, so I own nothing.”

Not necessarily. Under Article 147, care and maintenance of the family may count as contribution.

4. “My live-in partner will automatically inherit from me.”

False. A live-in partner is not a legal spouse and does not inherit by intestate succession merely by cohabitation.

5. “I can donate all my property to my live-in partner.”

Not always. Donations between live-in partners may be restricted or void, especially if the relationship is adulterous, illicit, or designed to evade legal prohibitions.

6. “A married person can freely buy property with a live-in partner.”

Not safely. If one partner is legally married to someone else, the lawful spouse and matrimonial property regime may be affected.

7. “Only cash contribution matters.”

Not always. Under Article 147, work, industry, and household care may matter. Under Article 148, actual contribution is required and must be proven.

XXII. Comparison Between Article 147 and Article 148

Article 147 applies when the parties are capacitated to marry each other. It generally presumes equal ownership of wages, salaries, and properties acquired through joint efforts during cohabitation. Domestic work and care of the family are recognized as contribution.

Article 148 applies when the parties are not capacitated to marry each other or the relationship is otherwise legally impeded. It requires proof of actual contribution. Ownership is proportionate to contribution. The law is stricter because of the presence of an existing marriage or other legal impediment.

The practical difference is enormous. A partner under Article 147 may rely on presumptions of equal ownership. A partner under Article 148 must be prepared to prove actual contribution.

XXIII. Death of One Partner

When one partner dies, the surviving partner should distinguish between ownership and inheritance.

The surviving partner may claim:

His or her own share in co-owned property;
Reimbursement for contributions;
Payment of debts owed by the deceased;
Property validly given by will, subject to legitime and legal restrictions;
Insurance or benefits where validly designated.

But the surviving partner does not automatically inherit as a spouse.

The deceased partner’s heirs may challenge the surviving partner’s possession or ownership. Conversely, the surviving partner may challenge the heirs if they attempt to include co-owned property entirely in the estate.

Estate settlement proceedings may be necessary.

XXIV. Relationship With the Lawful Spouse

If one partner is married to someone else, the lawful spouse’s rights must be considered.

The lawful spouse may claim that property acquired during the marriage belongs to the absolute community or conjugal partnership. The live-in partner may claim only what he or she actually contributed, especially under Article 148.

This can result in complex disputes among:

The married partner;
The lawful spouse;
The live-in partner;
Legitimate children;
Illegitimate children;
Creditors;
Heirs.

Courts will examine the source of funds, timing of acquisition, good faith or bad faith, and applicable property regime of the valid marriage.

XXV. Tax Considerations

Transfers of property between unmarried partners may have tax consequences. Depending on the transaction, possible taxes may include donor’s tax, capital gains tax, documentary stamp tax, estate tax, transfer tax, value-added tax, income tax, or registration fees.

A transaction labeled as a sale may be questioned if no real consideration was paid. A transaction labeled as a donation may be void or taxable. Property settlements may also have tax implications.

Tax advice should be obtained before transferring real property or substantial assets.

XXVI. Best Practices for Unmarried Partners

Unmarried partners who acquire property together should consider the following:

Put agreements in writing.
Register property in both names if both are intended owners.
State ownership percentages clearly.
Keep receipts and bank records.
Avoid mixing separate and common funds without documentation.
Record contributions to purchase price, improvements, taxes, and loans.
Make a will if intending to benefit a partner upon death.
Review beneficiary designations.
Avoid prohibited donations.
Consider the rights of children, lawful spouses, and compulsory heirs.
Seek legal advice before buying real property, especially if one party is married or foreign.
Settle property issues in writing upon separation.

XXVII. Conclusion

Unmarried partners in the Philippines do not acquire the same property rights as married spouses. There is no automatic common-law marriage. However, Philippine law does recognize property rights arising from cohabitation.

The governing rule depends primarily on whether the relationship falls under Article 147 or Article 148 of the Family Code.

If the partners were capacitated to marry each other, Article 147 generally provides a more protective regime, including presumptions of equal ownership and recognition of domestic care as contribution.

If the partners were not capacitated to marry each other, Article 148 applies a stricter rule: only actual contributions count, and ownership is proportionate to those contributions.

The most important lessons are simple but often ignored. Title is important, but it is not always the whole story. Contribution matters. Documentation matters. A live-in partner is not automatically an heir. Donations may be restricted. The rights of lawful spouses, children, heirs, and creditors may intervene.

For unmarried partners, property planning is not a sign of distrust. It is a practical necessity. Clear agreements, proper registration, and careful record-keeping can prevent years of litigation and protect both parties from uncertainty, hardship, and unfair loss.
