Quick answer

Before signing, confirm who is bound, what each party must do, when performance is due, how payment and acceptance work, who bears each risk, how the agreement ends, and where disputes must be brought. Verify the other party’s identity, ownership and authority; read every annex and incorporated policy; remove blanks; and keep the final signed version.

Before enforcing, confirm that the contract is valid and binding, the obligation is already due, you performed or were ready to perform your part, all notice or cure requirements were followed, and the claim is still within the applicable deadline. A written demand is often the practical first step, but arbitration, barangay conciliation, a government complaint process or another condition may have to come before court action.

Under the Civil Code, contractual obligations generally have the force of law between the parties and must be performed in good faith. A signature, however, does not cure illegality, lack of authority, defective consent or a legally required form. Notarization also does not automatically make an invalid agreement valid.

Start with the parties and their authority

Use the parties’ complete legal names, not merely brands, screen names or store names. Record reliable addresses, contact details and identification information appropriate to the transaction.

For an individual, check that the person is at least 18 and legally capable of giving consent. Philippine majority generally begins at 18 under Republic Act No. 6809. Contracts involving minors or persons unable to give valid consent require special care and may be voidable or otherwise restricted.

For a business, determine its legal form:

A sole proprietorship is not a separate juridical person from its proprietor. The proprietor—not merely the business name—should be properly identified.
A corporation, partnership, cooperative or association should be identified by its registered name and registration details.
A branch, employee or sales representative may lack authority to commit the principal to unusual terms.

You can check a Philippine business name through the DTI Business Name Search and obtain company filings through the SEC’s eSEARCH. Registration confirms certain public records; it does not by itself prove that a particular person may sign the specific contract.

Ask for the authority appropriate to the transaction, such as a board resolution, secretary’s certificate, special power of attorney, partnership authorization or written delegation. Article 1317 of the Civil Code provides that a person generally cannot contract in another’s name without legal or granted authority. A contract made without authority or beyond it is unenforceable against the purported principal unless properly ratified.

If marital or jointly owned property is involved, determine who owns it and whose written consent is required. Dispositions or encumbrances of community or conjugal property may be void without the other spouse’s written consent or court authority under the Family Code. Ownership and marital-property questions should be resolved before money changes hands.

Check whether a valid agreement actually exists

Article 1318 of the Civil Code requires:

Consent of the parties;
A sufficiently certain object or subject matter; and
A lawful cause or basis for the obligation.

The offer and acceptance must match. An “acceptance” that changes price, scope, timing or another material term is normally a counteroffer, not final acceptance.

Consent must be real and informed. A contract may be voidable when consent was obtained through mistake, violence, intimidation, undue influence or fraud. If a person cannot read the agreement or does not understand its language and later alleges mistake or fraud, Article 1332 places on the enforcing party the burden of showing that the terms were fully explained.

Clauses cannot validly defeat law, morals, public order or public policy. The contract must also bind both parties; its validity or compliance cannot simply be left to the uncontrolled will of one party. A standard-form or “take it or leave it” contract is not automatically invalid, but oppressive, obscure or unconscionable terms may receive close judicial scrutiny, especially where bargaining power was seriously unequal.

Make every important obligation measurable

Do not sign descriptions such as “as needed,” “high quality,” “promptly” or “to the client’s satisfaction” without objective standards. State:

The exact goods, property, services, rights or deliverables;
Quantity, specifications, condition and permitted substitutions;
Place, date and manner of delivery or performance;
Milestones and dependencies;
Inspection, testing and acceptance criteria;
Who may reject work and for what reasons;
The correction or replacement period;
Whether silence counts as acceptance;
Ownership of work product and intellectual property;
Required permits, licences, insurance and regulatory approvals; and
Which party supplies information, access, equipment or approvals.

Attach specifications, quotations, plans, inventories and schedules. Give every annex a title and date, and state which document prevails if provisions conflict. Avoid links to online policies that the other party may change unilaterally. If a linked policy must be used, save the version accepted on the signing date.

Recalculate the full financial exposure

Check more than the headline price. Identify:

VAT and other taxes;
Delivery, installation, maintenance and platform charges;
Reimbursable expenses;
Deposits and whether they are refundable;
Currency and exchange-rate rules;
Payment milestones and invoicing requirements;
Withholding taxes;
Late charges, penalties and collection costs;
Price-adjustment formulas; and
Events permitting suspension or acceleration.

For a loan or forbearance, interest must be expressly stipulated in writing under Article 1956 of the Civil Code. State whether the rate is monthly or annual, whether it is fixed or variable, how it is calculated, and whether unpaid interest is capitalized. Courts may reject or reduce unconscionable interest, penalties and liquidated damages. Article 1229 permits equitable reduction of a penalty after partial or irregular compliance, or when the penalty is iniquitous or unconscionable.

The legal interest rate is not a universal substitute for careful drafting. Its application and starting date depend on the kind of obligation, the existence of a valid stipulation, default, demand and the nature of the award. Current Supreme Court guidance appears in Lara’s Gifts & Decors, Inc. v. Midtown Industrial Sales, Inc., while BSP Circular No. 799 sets 6% per year for a loan or forbearance in the absence of a stipulation.

Do not assume attorney’s fees will automatically be recovered. Article 2208 allows them only under a valid stipulation or specified legal grounds, and the amount must remain reasonable.

Allocate risk clearly

Review provisions on:

Warranties and disclaimers;
Indemnity;
Limits or exclusions of liability;
Loss, damage and transfer of ownership;
Force majeure;
Insurance;
Confidentiality and data protection;
Non-solicitation or restrictions after termination;
Assignment and subcontracting; and
Liability for third-party suppliers.

A force-majeure label does not automatically excuse performance. Article 1174 generally addresses events that could not be foreseen or, though foreseen, were inevitable, subject to the law, the contract, the nature of the obligation and the party’s conduct. The clause should cover notice, mitigation, temporary suspension, prolonged disruption and termination.

Check whether an exclusion of liability improperly attempts to excuse fraud, bad faith, grossly wrongful conduct or a non-waivable statutory duty. Signing a waiver does not necessarily remove protections imposed by consumer, employment, housing, banking, insurance or other special laws.

Understand how the contract ends

State the duration, renewal mechanism and consequences of expiry. Look carefully for automatic renewal and short non-renewal windows.

Termination provisions should identify:

Termination for breach;
Any notice and cure period;
Termination for convenience;
Immediate-termination events;
Amounts payable upon termination;
Return of deposits, property and confidential information;
Transition or turnover duties; and
Provisions that survive termination.

Do not assume every breach permits immediate cancellation. Under Article 1191, the injured party in a reciprocal obligation may seek fulfillment or resolution, with damages in an appropriate case, but the remedy depends on the seriousness of the breach, the contract and the facts. Some cancellations require court action or a special notice process. Installment sales of real property, installment sales of personal property, residential leases, employment contracts and regulated consumer transactions can have additional statutory rules.

Read the dispute clause before there is a dispute

A dispute clause can change the cost and practicality of enforcement. Check:

Philippine or foreign governing law;
Exclusive or non-exclusive court venue;
Mediation or negotiation requirements;
Arbitration institution, seat, language and number of arbitrators;
Allocation of filing and professional fees;
Notice addresses and permitted delivery methods; and
Whether urgent interim relief remains available.

A written exclusive-venue agreement made before suit can displace the ordinary venue rules. Venue is different from subject-matter jurisdiction: parties cannot give a court authority that the law withholds.

An arbitration agreement may require the dispute to be referred to arbitration instead of being tried on the merits in court. Arbitration agreements are recognized by the Arbitration Law, the Alternative Dispute Resolution Act and the Supreme Court’s Special ADR Rules. Specify whether arbitration is mandatory; wording that merely gives a party a “right” to arbitrate may be treated as optional, depending on the complete clause.

Check writing, notarization and registration requirements

Contracts are generally binding in whatever form they were made if all essential requirements are present. Exceptions arise when law requires a particular form for validity, enforceability, proof, registration or effect against third persons.

The Civil Code’s Statute of Frauds requires a signed writing or memorandum 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;
Certain agreements made in consideration of marriage;
A sale of goods, chattels or things in action at a price of at least ₱500, subject to statutory exceptions;
A lease longer than one year;
A sale of real property or an interest in it; and
A representation concerning a third person’s credit.

The Statute of Frauds generally concerns executory agreements. Acceptance of benefits or failure to object to oral proof can amount to ratification, but relying on those exceptions is risky. Put the entire deal in writing.

Some transactions have stricter formalities. For example, a donation of immovable property requires a public document and compliant acceptance. Real-property rights ordinarily require a public instrument for registration. A public document may also be required for certain powers of attorney, hereditary rights and other transactions listed in Article 1358. Transaction-specific law may impose additional signing, witnessing, registration or approval requirements.

Notarization commonly converts a private instrument into a public document and strengthens its evidentiary standing, but it is not a universal validity requirement and does not establish ownership or cure an unlawful agreement. For conventional notarization, signatories must personally appear, present competent proof of identity and use a complete document. A notary must not notarize a blank or incomplete instrument under the Supreme Court’s Amended Notarial Rules.

Electronic notarization is now available under the 2025 Rules on Electronic Notarization. It must be performed through the authorized process by an electronically commissioned notary. A scanned signature or an ordinary video call with a notary is not, by itself, compliant electronic notarization.

Registration is a separate act. A notarized deed involving land, for example, is not automatically registered with the Registry of Deeds.

Verify the property or asset

For land or a condominium, obtain a recent government-issued certified true copy of the title—not merely a seller’s photocopy. The LRA’s eSerbisyo portal permits requests for certified true copies of OCTs, TCTs and CCTs. Compare the registered owner, technical description and annotations, and investigate mortgages, adverse claims, liens, pending cases, restrictions and unpaid obligations.

Also examine tax declarations, real-property tax receipts, surveys, possession, occupants, rights of way, condominium records, zoning and required permits. A clean-looking title is not the only due-diligence issue.

For equipment, vehicles, inventory or other personal property, verify serial numbers, ownership documents and existing liens. Registered security interests over personal property may be searched through the LRA’s Personal Property Security Registry.

Sign in a way that preserves proof

Before signing:

Resolve every tracked change and comment.
Remove blanks or mark them “not applicable.”
Check page numbers and defined terms.
Confirm every annex is present.
Use consistent dates and amounts in figures and words.
Initial material handwritten changes.
Ensure every required party signs.
Obtain the signatory’s authority documents.
Give each party an identical final copy.
Record the actual date of signing rather than backdating.
Complete notarization, tax and registration steps on time.

Electronic contracts and signatures can be legally recognized under the Electronic Commerce Act. Recognition depends on reliable identification, consent, integrity and authentication. The law does not eliminate special formalities required by other statutes.

Preserve the native electronic file, audit certificate, time stamps, email transmission, verification records and complete signing history. A screenshot alone may omit metadata needed to authenticate the document under the Rules on Electronic Evidence.

Before trying to enforce the contract

1. Identify the exact obligation and breach

Read the complete agreement, amendments and incorporated documents. Determine:

What obligation was due;
When and where it became due;
Whether a condition precedent occurred;
Whether your own performance was complete or properly offered;
Whether performance was accepted;
Whether the other party has a defence, offset or counterclaim; and
What remedy the contract and law permit.

In reciprocal obligations, a party may not place the other in delay while failing or being unready to perform its own corresponding obligation properly.

2. Check the notice and cure provisions

Follow the agreed method exactly. A notice sent to the wrong address or only through an unapproved messaging app may be disputed. Use a method that proves contents, dispatch and receipt.

Article 1169 generally places an obligor in delay from judicial or extrajudicial demand. Demand is unnecessary in specified exceptions, including when the contract or law expressly says so, timing was a controlling reason for the agreement, or demand would be useless because performance has become impossible. Even where demand may not be legally indispensable, a clear written demand can narrow the dispute and document default.

A useful demand states:

The contract and parties;
The obligation and due date;
The facts constituting breach;
The amount or performance required;
A reasonable deadline consistent with the contract;
The contractual or legal remedy to be pursued; and
Where and how compliance should be made.

Avoid insults, public accusations, unlawful threats and inflated criminal claims. An ordinary failure to pay or perform is generally a civil matter; fraud or another offence requires separate facts and legal elements.

3. Preserve the evidence

Keep the original or best available version of:

The signed contract, amendments and annexes;
Authority documents and IDs;
Quotations, purchase orders and invoices;
Receipts, bank records and official payment confirmations;
Delivery receipts, inspection reports and acceptance records;
Emails, texts, platform messages and call records lawfully obtained;
Notices and proof of delivery;
Photos, videos and device-generated records in original format;
Work logs, inventories and damage calculations; and
Evidence of efforts to mitigate loss.

Export online conversations without deleting the originals. Record relevant URLs, account names, dates and times. Do not edit screenshots in a way that conceals context.

4. Calculate the remedy honestly

Possible remedies include performance, payment, repair, replacement, refund, resolution or cancellation, restitution and damages. The available remedy depends on the agreement, the type and seriousness of breach, special law and proof.

Actual damages generally require competent evidence. Contractual penalties or liquidated damages may reduce the need to prove the precise loss, but a court can reduce an unconscionable amount. Do not claim attorney’s fees, moral damages or exemplary damages as automatic additions.

5. Follow the required dispute path

Before filing a case, check for:

Mandatory negotiation or mediation;
A binding arbitration agreement;
Barangay conciliation;
An agency complaint or administrative remedy;
A contractual expert-determination process; and
A special statutory demand or cure period.

Katarungang Pambarangay conciliation may be a condition before court action in disputes within the lupon’s authority, particularly between individuals actually residing in the same city or municipality. The Local Government Code contains exceptions, including certain urgent actions, disputes involving government parties, specified criminal matters and cases where the limitation period may expire. Filing prematurely can result in dismissal or suspension.

6. Choose the correct forum

A pure money claim of not more than ₱1,000,000, excluding interest and costs, arising from a qualifying contract may proceed under the current small-claims rules. Lawyers generally cannot represent parties at the hearing unless the lawyer is personally a party, although a party may consult counsel before filing. Use the Supreme Court’s current small-claims rules and forms and confirm the filing method with the proper first-level court or eCourt PH, since electronic-filing implementation can depend on the court and current judiciary directives.

Small claims do not cover every contractual remedy. Claims involving title to property, injunctions, complex non-monetary relief, matters assigned to specialized tribunals or amounts outside the rule may require another forum.

Consumer complaints involving goods or services under DTI jurisdiction may be filed through the DTI Consumer CARe System. For an online transaction, Section 24 of the Internet Transactions Act generally requires an aggrieved party to use the platform, marketplace or e-retailer’s internal redress mechanism before resorting to a government agency or court.

For a bank, e-wallet or other BSP-supervised institution, first complain through the institution’s Financial Consumer Protection Assistance Mechanism. An unresolved complaint may then be escalated through the BSP Consumer Assistance Channels and BOB.

Employment, construction, agrarian, insurance, housing, securities and regulated utility disputes may belong to specialized agencies or tribunals. The contract’s label does not control statutory jurisdiction.

Do not miss the deadline

Prescription is calculated from the accrual of the right of action, not automatically from the date the contract was signed.

Under the Civil Code, the general periods include:

10 years for an action upon a written contract;
6 years for an action upon an oral contract; and
4 years for annulment of a voidable contract, with the starting point depending on incapacity, discovery of mistake or fraud, or cessation of violence, intimidation or undue influence.

Special laws and particular causes of action may impose much shorter periods. Ejectment, consumer warranties, insurance claims, transportation claims, arbitration rules and contractual notice provisions require separate checking.

Article 1155 provides that prescription is interrupted by filing in court, a written extrajudicial demand by the creditor, or the debtor’s written acknowledgment of the debt. Do not rely on an informal call or an unprovable message. Also do not assume that a demand cures a period that has already expired.

Common mistakes to avoid

Signing for the wrong legal entity;
Trusting a job title without verifying authority;
Paying before checking ownership or encumbrances;
Leaving price, scope or delivery details to later discussion;
Signing with missing annexes or blank spaces;
Treating notarization as proof of ownership or legality;
Assuming every electronic signature is automatically authenticated;
Ignoring automatic renewal, arbitration or exclusive-venue clauses;
Accepting unilateral price changes without an objective formula;
Failing to protest incomplete or defective performance;
Sending demand through a method the contract does not recognize;
Terminating immediately despite a required cure period;
Disposing of, altering or deleting electronic evidence;
Publicly shaming a debtor or making unsupported criminal threats;
Waiting until the prescriptive period is nearly over; and
Filing in court without completing required barangay, arbitration or agency steps.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A deadline, foreclosure, eviction, repossession or termination is imminent;
The other party is transferring assets or destroying evidence;
An injunction, attachment or other provisional remedy may be needed;
Land, a home, inheritance or marital property is involved;
The agreement contains foreign law, foreign venue or arbitration;
A signatory’s authority or a party’s capacity is disputed;
Fraud, forgery, coercion or identity theft is suspected;
The contract involves a large loan, personal guaranty or security over essential assets;
You are being asked to sign a waiver, quitclaim or settlement after a dispute;
A government permit or regulated activity is involved; or
The amount or consequence is too significant to risk on an unreviewed template.

FAQ

Is a signed contract always enforceable?

No. A signed agreement may still be void, voidable, rescissible or unenforceable because of illegality, defective consent, incapacity, lack of authority, an uncertain subject or failure to comply with a legally required form. The classification determines the available remedy and deadline.

required form. The classification determines Can an oral contract be enforced?

Sometimes. Philippine law generally recognizes contracts regardless of form when the essential requirements are present. The Statute of Frauds and special laws, however, require writings or other formalities for particular transactions. Oral terms are also harder to prove.

Does notarization make a contract valid?

Not necessarily. Notarization strengthens the document’s public and evidentiary character but does not cure illegality, fraud, lack of authority or a missing essential requirement. Some transactions independently require a public instrument or registration.

Is an electronic signature valid?

It can be. The Electronic Commerce Act recognizes electronic documents and signatures when the applicable identification, consent, reliability, integrity and authentication requirements are met. Special statutory formalities still apply.

Can I cancel within three days after signing?

There is no universal three-day cancellation right for all Philippine contracts. A cancellation, cooling-off or refund right must come from the contract or a law governing that transaction. Do not assume it exists.

Must I send a demand letter before suing?

Often, but not always. Demand commonly establishes delay and may be required by the contract or special law. Article 1169 recognizes exceptions. The correct answer depends on the obligation, its due date and the relief sought.

How long do I have to enforce a written contract?

The general Civil Code period is 10 years from accrual of the cause of action, but special rules may be shorter and determining accrual can be disputed. Obtain advice early instead of treating ten years as a safe waiting period.

Can I enforce an excessive penalty exactly as written?

Not necessarily. Courts may reduce contractual penalties or liquidated damages that are iniquitous or unconscionable, as well as penalties where the principal obligation was partly or irregularly performed.

Can I go directly to small claims court?

Only if the claim falls within the small-claims rule and any required preliminary process has been completed. Arbitration, barangay conciliation, an online platform’s redress process or another statutory remedy may have to be addressed first.
