Quick answer

Before signing, confirm five things: who is bound, what each side must do, when performance is due, how much it will cost, and what happens if something goes wrong. Verify identities, ownership and signing authority; read every annex; remove blanks; clarify vague standards; and make sure the required signatures, writing, notarization, registration or approval will be completed.

Before enforcing, identify the controlling version of the agreement, the exact obligation breached, whether it was already due, whether you performed your own obligations, and whether the required notice, demand, cure period, mediation or arbitration steps were followed. Check prescription immediately. A strong demand letter cannot make an invalid contract valid, excuse your own non-performance or recover an amount unsupported by the agreement and evidence.

Under the Philippine Civil Code, contractual obligations generally have the force of law between the parties and must be performed in good faith. But freedom of contract is limited by law, morals, good customs, public order and public policy. A contract may also be void, voidable, rescissible or unenforceable because of illegality, defective consent, incapacity, lack of authority or failure to comply with a required form. See Articles 1159, 1306 and 1380–1422 of the Civil Code.

Check whether a valid agreement was formed

A contract ordinarily requires:

Consent: a definite offer and an absolute acceptance, showing a real meeting of minds;
A certain object: identifiable property, goods, services, rights or obligations that may lawfully be contracted over; and
A lawful cause or consideration: the legally recognized reason for each party’s undertaking.

A qualified acceptance is generally a counter-offer, not acceptance of the original offer. Negotiations, quotations, advertisements, unsigned drafts and letters of intent do not necessarily create the final contract. Their wording and the parties’ conduct matter.

Signing is not conclusive if consent was obtained through material mistake, violence, intimidation, undue influence or fraud. Such contracts are generally voidable and remain binding until annulled. By contrast, an agreement with an illegal or impossible object or purpose may be void from the beginning and cannot be cured merely by ratification, payment or notarization.

Do not assume that an unfair-looking deal is automatically void. Courts generally respect freely negotiated terms. The legal question is whether a clause violates law or public policy, leaves validity or compliance entirely to one party’s will, or is otherwise legally unconscionable in the circumstances.

Verify every party and signatory

The contract should use each party’s complete legal name, address and reliable identification details. For businesses, distinguish among:

An individual using a DTI-registered business name;
A partnership or corporation registered with the Securities and Exchange Commission;
A cooperative;
An association, estate, trust or other entity; and
A branch, affiliate or trade name that may not itself be the contracting entity.

A DTI business name does not, by itself, create a corporation separate from its proprietor. Match the proprietor’s identity to the registration. For a corporation, verify its exact registered name and current records through the SEC’s official verification services. A registration certificate confirms registration; it does not prove that the entity is solvent, properly licensed for every activity or authorized for the specific transaction.

Ask for documentary authority when someone signs for another person or entity. Depending on the transaction, this may include:

A board resolution and secretary’s certificate;
Partnership or corporate approvals;
A special power of attorney;
A guardianship or court order;
Estate-settlement authority; or
Written authority from the owner.

Article 1317 of the Civil Code generally makes a contract entered into without authority, or beyond the representative’s authority, unenforceable against the supposed principal unless properly ratified. Special authority is required for important acts listed in Article 1878, including borrowing money, acting as guarantor or surety, compromising claims, submitting disputes to arbitration, transferring ownership of immovable property and leasing real property for more than one year. An agent’s authority to sell land must be in writing; otherwise, Article 1874 declares the sale void.

For a corporation, do not rely solely on a job title, company email address or business card. Confirm whether the board or a properly authorized officer approved the transaction under the Revised Corporation Code.

Confirm ownership, permits and third-party rights

A party cannot safely promise more than it owns or is authorized to provide. Conduct due diligence appropriate to the subject:

Land or condominium: obtain a recent certified true copy of the title, examine annotations, compare the technical description, identify mortgages, adverse claims, liens and restrictions, and verify the seller’s civil status and authority. Certified copies may be requested through the Land Registration Authority’s eSerbisyo portal.
Community or conjugal property: determine whether the other spouse’s written consent or court authority is required. Disposition or encumbrance without the approval required by the Family Code can have serious validity consequences.
Vehicles and equipment: inspect registration, serial numbers, liens and actual possession.
Intellectual property: verify ownership, registration where relevant, permitted uses, territorial scope and whether third-party materials are included.
Regulated businesses or projects: check permits, professional licences, zoning, regulatory approvals and any approval conditions.
Assigned rights or receivables: verify the original contract, the chain of assignment, notice requirements and restrictions on assignment.

A clean-looking photocopy is not enough for a high-value transaction. Compare it with an independently obtained government or custodian-issued record.

Read the commercial terms as an operating plan

A useful contract should answer practical questions without forcing either side to guess.

Scope and standards

Identify precisely:

The goods, services, property or rights covered;
Quantities, specifications, plans, milestones and deliverables;
Who supplies materials, access, information or approvals;
Acceptance tests and who decides whether work is acceptable;
The correction or rejection process;
Change-order procedures; and
Which document controls if the main agreement, proposal, purchase order and annexes conflict.

Avoid standards such as “satisfactory,” “as needed” or “industry standard” unless the agreement provides objective criteria or a reasonable decision process.

Price, taxes and payment

State the total price or a clear formula, currency, payment dates, billing requirements and the party responsible for taxes, withholding, delivery, permits, bank fees and reimbursable expenses.

For loans and deferred payments, distinguish:

Principal;
Conventional or monetary interest;
Penalty or compensatory interest;
Late charges;
Collection costs; and
Attorney’s fees.

Article 1956 of the Civil Code provides that monetary interest is not due unless expressly stipulated in writing. Stipulated interest and penalties are not automatically beyond judicial review. Courts may reduce an iniquitous or unconscionable rate or an excessive penalty. Current Supreme Court guidance on monetary and compensatory interest appears in Lara’s Gifts & Decors, Inc. v. Midtown Industrial Sales, Inc.. When applicable and in the absence of an enforceable stipulated rate, the prevailing legal rate is generally 6% per annum, but the correct base amount and starting date depend on the nature of the obligation, default, demand and judgment.

Timing and conditions

Specify whether dates are calendar days, business days or working days; what timezone applies; and what happens when a deadline falls on a holiday. Identify:

The effective date and commencement date;
Conditions that must occur before obligations begin;
Delivery and payment milestones;
Notice and cure periods;
Renewal, extension and expiration rules; and
Whether time is expressly essential.

Watch for automatic renewal clauses and short cancellation windows. Put critical dates in a separate calendar after signing.

Risk, warranties and remedies

Review who bears the risk of:

Loss or damage before delivery or acceptance;
Delay caused by permits, suppliers or third parties;
Defects, rework and recalls;
Data loss or security incidents;
Infringement claims;
Accidents and property damage; and
Events outside the parties’ control.

A force-majeure clause should define covered events, notice duties, mitigation, suspension, allocation of costs and the point at which either side may terminate. Article 1174 provides a general rule for unforeseeable or inevitable events, but the law, the contract or the nature of the obligation may allocate the risk differently. Ordinary financial difficulty, avoidable supply problems or an event that did not actually prevent performance should not automatically be treated as force majeure.

Check limitations of liability, exclusions of consequential damages, indemnities, insurance requirements, warranties and disclaimers together. A limitation should identify whose liability is limited, which claims are capped and which claims are excluded from the cap. A waiver of liability for future fraud is void under Article 1171.

Termination and exit

Distinguish expiration, cancellation for convenience and termination for breach. State:

Which breaches permit termination;
Whether the breach must be substantial;
Whether notice and an opportunity to cure are required;
What happens to deposits, unfinished work and customer data;
Which amounts become immediately due;
Return or destruction obligations; and
Which clauses survive termination.

Article 1191 generally allows the injured party in a reciprocal obligation to seek fulfillment or rescission, with damages in either case, for a sufficiently serious breach. Whether a party may terminate without first obtaining a judicial decree depends on the contract, the type of transaction and the circumstances. Improper self-help termination can itself become a breach.

Review dispute, venue and governing-law clauses

A dispute clause can determine the cost and speed of enforcement. Check whether the contract requires:

Management negotiations;
A notice of dispute;
Mediation;
Barangay conciliation;
Arbitration; or
Court litigation.

For arbitration, identify the seat, administering institution or rules, number and appointment of arbitrators, language, interim-relief procedure, confidentiality and cost allocation. A written arbitration agreement is generally respected under the Alternative Dispute Resolution Act, and a court may refer a covered dispute to arbitration. Do not file in court first without checking this clause.

A venue clause should say whether the named place is exclusive or merely permitted. Jurisdiction is conferred by law, not by agreement, and cannot be created by choosing a particular court. Foreign governing law or a foreign forum may also create proof, public-policy, service and enforcement issues; obtain advice before accepting one.

Check required form, notarization and registration

The general rule under Article 1356 is that a contract may be obligatory in any form if its essential requisites exist. Important exceptions apply where the law requires a particular form for validity, enforceability, proof or registration.

The Statute of Frauds in Article 1403 generally requires a signed writing for certain still-executory agreements, including:

An agreement not to be performed within one year;
A special promise to answer for another person’s debt or default;
A lease longer than one year;
A sale of real property or an interest in it; and
Other transactions listed in the article.

The Statute of Frauds has important limits. It generally concerns executory—not already performed—agreements, and noncompliance may be ratified by accepting benefits or failing to object to oral evidence. Do not apply it mechanically without examining performance and the exact documents.

Notarization usually converts a private instrument into a public document with stronger evidentiary consequences. It does not make a forged, illegal or otherwise invalid contract valid. The Supreme Court has expressly warned that forged documents remain void despite notarization. Signers should personally appear before a duly commissioned notary with competent proof of identity. Never sign an incomplete document for later notarization outside your presence.

Some transactions require registration or another public act to affect third parties. A private deed of sale, for example, is not the same as transferring a registered land title. Confirm the taxes, clearances, notarization, registration and delivery steps instead of treating the signature page as the end of the transaction.

Treat electronic signing carefully

Electronic contracts and signatures are legally recognized when the statutory requirements are met. The Electronic Commerce Act recognizes electronic documents that retain integrity and reliability and can be authenticated. It also recognizes an electronic signature when the prescribed method reliably identifies the signer, indicates consent and permits verification.

A pasted image of a signature is not automatically self-proving. Preserve:

The final signed file, not only a screenshot;
Audit trails and completion certificates;
Account and access records;
Email transmission records;
Time stamps and verification logs;
Prior drafts and the final-version identifier; and
Evidence that the signer had authority and received all incorporated terms.

Electronic form does not override a law requiring additional formalities for validity. If the transaction requires notarization, registration, witnesses or a special form, confirm whether and how those requirements can lawfully be completed.

Before signing: a final-document checklist

Do not sign until you can answer yes to each applicable item:

The names, addresses and capacities of all parties are correct.
Each signatory’s authority has been independently verified.
The subject matter is lawful, owned or controlled by the promising party, and sufficiently described.
The price, taxes, interest, penalties and payment mechanics are complete.
Deliverables, acceptance standards and deadlines are objective.
Every annex, schedule, policy and online term has been received and reviewed.
Conflicts among documents are resolved by an order-of-precedence clause.
There are no blanks, unexplained handwritten changes or inconsistent page numbers.
Renewal, termination, refund and deposit rules are understood.
Liability, indemnity, warranty and insurance clauses fit the actual risk.
Notice addresses and approved delivery methods are correct.
Dispute resolution, venue and governing law are workable.
Required spouse, board, owner, lender or government approvals are documented.
Required notarization, witnesses and registration have been planned.
Each party will receive an identical, complete signed copy.

Initial material handwritten changes and attach the final annexes before execution. Keep negotiation records, but make sure every promise you rely on appears in the final contract. Under the parol-evidence rule, a written agreement is generally treated as containing the parties’ terms, subject to specific exceptions that must be properly raised under the 2019 Amendments to the Rules on Evidence.

Before enforcing: establish the breach

Start with a written chronology. Identify:

The controlling contract and every amendment.
The obligation allegedly breached.
The contractual or legal due date.
Any condition precedent to that obligation.
Your own performance or readiness to perform.
The other party’s act, omission or refusal.
The notice and cure provisions.
The loss caused by the breach.
The remedy authorized by the contract and law.
The earliest possible prescription deadline.

In reciprocal obligations, a party that has not performed or properly offered its own due performance may have difficulty placing the other in default. Partial or defective performance, acceptance without protest, waiver, estoppel, novation and prior breaches can also change the analysis.

Do not claim every disagreement is a material breach. A minor breach may justify damages or correction without supporting termination or rescission of the entire agreement.

Send a legally useful demand

Unless an exception applies, Article 1169 generally places an obligor in delay when fulfillment is demanded judicially or extrajudicially. Demand may be unnecessary when the contract or law expressly says so, when the agreed time was a controlling motive, or when demand would be useless because performance has become impossible.

A demand should ordinarily:

Identify the contract and parties;
State the relevant obligation and facts;
Attach or quote the critical provisions accurately;
Provide a transparent computation;
Demand a specific act or payment;
Give the contractual cure period or a reasonable deadline;
State the remedy that may follow, without making unlawful threats;
Reserve rights without contradicting any remedy already elected; and
Be delivered through every contractually required channel.

Address it to the correct individual and legal entity. Preserve proof of dispatch and actual receipt. A written extrajudicial demand may also interrupt prescription under Article 1155, but do not wait until the last day or assume an unreceived message will be sufficient.

Nonpayment of a contractual debt is not, by itself, automatically a criminal offense. Avoid threats of arrest, public shaming, harassment or seizure of property without lawful process.

Preserve evidence and reduce further loss

Keep originals and create read-only backups of:

The complete signed contract and annexes;
Drafts showing disputed changes;
Board resolutions, powers of attorney and identity records;
Invoices, official receipts and bank confirmations;
Delivery receipts, inspection records and acceptance certificates;
Emails with headers, messages and platform exports;
Photographs, videos and metadata;
Call notes made close to the event;
Repair estimates and replacement quotations;
Government records, permits and title documents;
Demand letters and proof of receipt; and
Evidence of efforts to cure or mitigate the loss.

Do not crop, rewrite or delete electronic records. Record where each item came from and who had custody. Article 2203 requires an injured party to exercise reasonable diligence to minimize resulting damages. Take proportionate steps to prevent avoidable losses without destroying evidence or waiving rights.

Choose the correct remedy and forum

Possible remedies include performance, payment, repair, replacement, price reduction, damages, rescission or termination, restitution, injunction and enforcement of security. The proper choice depends on the agreement, the seriousness of the breach and whether remedies may legally be combined.

Check these procedural routes before filing:

Contractual negotiation, mediation or arbitration: complete mandatory preliminary steps unless urgent relief or a recognized exception applies.
Barangay conciliation: under Sections 408 and 412 of the Local Government Code, covered disputes between parties residing in the same city or municipality generally require prior barangay proceedings, subject to statutory exceptions. A required certificate to file action may be a condition before going to court.
Small claims: qualifying money claims not exceeding ₱1,000,000, exclusive of interest and costs, may use the simplified procedure in first-level courts. The procedure is intended for direct party participation, although legal advice before filing remains useful. Consult the Supreme Court’s Rules on Expedited Procedures in the First Level Courts and current forms.
Ordinary civil action: larger or non-small-claims cases require the correct court, venue, allegations, supporting documents, filing fees, service and procedural compliance.
Special agency or tribunal proceedings: employment, construction, consumer, housing, insurance, securities, agrarian, intellectual-property and government-contract disputes may fall under special laws or bodies.

Full implementation of electronic filing guidelines for civil cases in trial courts began on 1 December 2024. The applicable method can depend on the court, case and whether a party is represented, so confirm the current requirements through the Supreme Court’s electronic-filing page or the relevant clerk of court.

Do not miss prescription

The Civil Code’s general periods include:

Ten years for an action upon a written contract, counted from accrual;
Six years for an action upon an oral contract;
Ten years for a mortgage action;
Four years for annulment of a voidable contract, with the starting point depending on incapacity, intimidation, violence, undue influence, mistake or fraud; and
Four years for the rescission described in Article 1389.

These are not universal deadlines. Special laws, the nature of the cause of action, installment obligations, acceleration clauses, acknowledgment of debt, demand, prior proceedings and the relief requested can alter the period or its starting point. A contract cannot safely be classified as “written” merely because some messages exist. Have prescription assessed as soon as a dispute appears.

Common mistakes

Signing under the wrong corporate, trade or personal name;
Accepting a signatory’s authority without documentary proof;
Relying on verbal assurances omitted from the final contract;
Signing before all annexes and schedules are attached;
Treating notarization as proof of ownership, authority or legality;
Paying to a personal account without confirming that the recipient may receive payment;
Ignoring automatic renewal or short cancellation periods;
Using inconsistent interest, penalty and attorney-fee computations;
Terminating immediately despite a required notice-and-cure period;
Assuming every force-majeure notice excuses performance;
Filing in court despite a valid arbitration clause;
Skipping mandatory barangay conciliation;
Sending demands only to an inactive email address;
Waiting until prescription is near;
Altering screenshots or deleting original electronic records; and
Seizing property, changing locks, disconnecting services or publishing accusations without a clear legal right.

When legal help is urgent

Seek prompt Philippine legal advice if:

A prescription, cancellation, foreclosure, arbitration or court deadline is approaching;
You received summons, a notice of arbitration, a foreclosure notice or a demand to vacate;
The contract involves land, a family home, a large loan, a guaranty or substantial security;
A signature, title, authority document or notarization may be forged;
A minor, incapacitated person, estate or absent owner is involved;
You need an injunction or other urgent order to prevent transfer, demolition, disclosure or dissipation of assets;
The agreement involves foreign law, a foreign party or enforcement abroad;
A government entity, regulated activity or public procurement is involved;
The transaction may violate criminal, anti-money-laundering, competition, consumer, labour, securities or data-privacy law; or
You plan to rescind, cancel, repossess, evict, foreclose or terminate a long-term relationship.

FAQ

Is a verbal contract valid?

It can be. Contracts are generally obligatory regardless of form when the essential requisites are present. However, some agreements must be written, notarized, witnessed, approved or registered for validity, enforceability, proof or effect against third parties. Proving the exact terms of an oral agreement is also more difficult.

Does my signature mean every clause will be enforced?

No. Signing is strong evidence of assent, and failing to read ordinarily does not erase agreed terms. But illegal, void, unauthorized or legally unconscionable provisions may not be enforced, and defective consent or incapacity may support an appropriate remedy.

Is a “take it or leave it” contract automatically invalid?

No. A standard-form or adhesion contract is not invalid solely because one party drafted it. Ambiguities may be construed against the drafter, and oppressive or unlawful terms may be reviewed, but enforceability depends on the clause and circumstances.

Must a contract be notarized?

Not always. Notarization is commonly used for evidentiary strength and is required or practically necessary for certain documents and registrations. It does not replace consent, authority, legality or other mandatory formalities.

Can emails or chat messages form a contract?

Potentially. Electronic communications can establish an offer, acceptance and terms if the parties, authority, intent, integrity and authenticity can be proved. Casual discussions, incomplete negotiations and messages subject to a later formal agreement may not be enough.

Can I cancel because the other side breached?

Possibly, but not every breach permits cancellation. Check whether the breach is substantial, whether a cure period applies, whether you performed your own reciprocal obligations and whether the contract authorizes extrajudicial termination. Wrongful cancellation may expose the cancelling party to liability.

Can I collect attorney’s fees just because the contract says so?

Not automatically in every amount claimed. A contractual clause is relevant, but courts may still examine whether an award is legally justified and reasonable. Keep invoices and evidence of the collection work or litigation expense.

Does a demand letter guarantee payment?

No. It can establish demand, document the dispute, trigger a cure period and potentially interrupt prescription, but enforcement may still require settlement, arbitration, agency proceedings or a court judgment. Collectability also depends on the debtor’s assets and available security.
