What to Check Before Signing or Enforcing a Contract

Quick answer

Before signing a contract, check who is bound, whether each signer has legal authority, exactly what each party must do, when performance is due, what happens if something goes wrong, and how disputes must be resolved. Do not rely on the title of the document, verbal assurances, or the fact that it will be notarized. Under Philippine law, contractual obligations generally have the force of law between the parties, but a contract may still be void, voidable, unenforceable, subject to special formalities, or ineffective against a supposed principal if essential legal requirements are missing. (eLibrary)

Before enforcing a contract, confirm that the obligation is already due, that any required condition or notice has been satisfied, that you have performed or are ready to perform your own corresponding obligations, and that the other party is actually in breach. Then check the contract's demand, cure, termination, arbitration, venue, and dispute-resolution provisions before filing anything. Depending on the parties and the claim, barangay conciliation or a special procedure such as small claims may also apply. (Lawphil)

Start with the basic question: is there a valid contract?

The Civil Code defines a contract as a meeting of minds whereby one person binds himself or herself, with respect to another, to give something or render some service. A contract generally requires three essential elements:

1. Consent of the contracting parties;
2. A certain object that is the subject of the contract; and
3. A lawful cause or consideration for the obligation.

A signed document is therefore important evidence, but the signature alone does not answer every legal question. If there was no genuine agreement on an essential matter, the supposed representative lacked the necessary authority, the object or cause is unlawful, or a mandatory legal form was ignored, enforceability may be affected. (Lawphil)

Parties are generally free to agree on their own terms, but Article 1306 of the Civil Code does not allow stipulations contrary to law, morals, good customs, public order, or public policy. Courts ordinarily enforce clear lawful contractual provisions rather than rewrite a bad bargain merely because one party later finds the agreement unfavorable. (Lawphil)

What to check before signing

1. Confirm the exact identity of every contracting party

Do not settle for a trade name, nickname, salesperson's name, Facebook account, or informal business name if another individual or juridical entity is supposed to carry the obligation.

For an individual, verify the person's complete legal name and identifying information appropriate to the transaction. For a corporation, partnership, association, or other entity, determine which legal entity is actually contracting.

This distinction matters. A contract normally binds the parties to it, not every owner, officer, employee, shareholder, relative, affiliate, or related company. Article 1311 of the Civil Code generally provides that contracts take effect between the parties, their assigns, and heirs, subject to recognized exceptions. (Lawphil)

2. Check whether the signer has authority

This is particularly important when somebody signs:

• for a corporation or partnership;
• as an attorney-in-fact;
• for a property owner;
• for an estate;
• for another family member; or
• in any other representative capacity.

Article 1317 provides that a person generally cannot contract in another's name without authority or a legal right to represent that person. An unauthorized contract made in another person's name is generally unenforceable against the supposed principal unless properly ratified. (Lawphil)

For a company transaction, depending on its nature, ask for appropriate proof of authority, such as a board authorization, secretary's certificate, partnership authority, or other corporate records. The mere fact that somebody holds an impressive job title does not necessarily establish authority for an extraordinary transaction. The Supreme Court has recognized that acts of corporate officers or representatives undertaken without the necessary delegated authority generally do not bind the corporation. (Lawphil)

Real-property transactions deserve special caution. When land or an interest in land is sold through an agent, Article 1874 requires the agent's authority to be in writing; Article 1878 also requires special authority for specified acts involving ownership or real rights over immovable property. (Lawphil)

3. Make sure the contract identifies exactly what is being exchanged

The contract should leave as little uncertainty as reasonably possible regarding:

• the property, goods, services, loan, work, or rights involved;
• quantities, specifications, scope, location, or identifying numbers;
• the price or consideration;
• taxes, fees, charges, reimbursements, and expenses;
• the payment schedule and payment method;
• who must issue receipts or supporting documents; and
• what constitutes complete performance.

A contract that says "services as needed," "reasonable expenses," "industry-standard work," or similar language may be workable in context, but vague wording increases the risk of later disagreement. Clear terms matter because, when contractual language is clear and leaves no doubt as to the parties' intention, the Civil Code generally gives effect to its literal meaning. (Lawphil)

4. Separate obligations, conditions, deadlines, and milestones

Ask:

What must happen first?

A party may not yet be in breach if the obligation is subject to a condition that has not occurred.

When does payment become due?

"Upon completion," "within 30 days," "after acceptance," and "after submission of complete documents" can produce very different results.

Who decides whether work is acceptable?

If acceptance depends on inspection, certification, testing, approval, or submission of documents, state the criteria and deadline.

Is time expressly essential?

This can affect when delay begins and whether prior demand is necessary.

In reciprocal obligations, one party ordinarily cannot put the other in delay while failing or refusing to perform what is correspondingly required of that party. Article 1169 provides that neither party incurs delay in reciprocal obligations if the other does not comply, or is not ready to comply properly, with what is incumbent upon that party. (Lawphil)

5. Read the default, penalty, interest, and acceleration clauses carefully

Do not review only the business terms on the first few pages. Check provisions dealing with:

• interest;
• penalties and liquidated damages;
• acceleration of the entire balance;
• forfeiture of deposits;
• attorney's fees;
• collection expenses;
• cross-default with another agreement;
• security deposits;
• mortgages, pledges, guarantees, or surety obligations; and
• rights to deduct, retain, or set off amounts.

A clause appearing in a standard-form contract is not automatically invalid merely because one party drafted it. The Supreme Court has repeatedly held that contracts of adhesion are not invalid per se, although particular provisions may be scrutinized depending on the circumstances, bargaining relationship, ambiguity, and applicable law. (Lawphil)

6. Check the termination and cancellation provisions

Determine:

• which breaches permit termination;
• whether advance notice is required;
• whether there is a cure period;
• whether termination is immediate for specified serious breaches;
• what happens to advance payments and deposits;
• whether completed work must still be paid;
• whether property must be returned;
• which obligations survive termination; and
• whether termination affects confidentiality, warranties, indemnities, or dispute-resolution clauses.

Do not assume that every breach permits cancellation of the entire contract. For reciprocal obligations, the Civil Code allows an injured party in appropriate cases to choose fulfillment or resolution of the obligation, with damages in either case, but Supreme Court doctrine generally requires a substantial or fundamental breach, not merely a slight or casual one, to justify resolution under Article 1191. (Lawphil)

Special contracts may follow more specific rules. A contract to sell, for example, may operate differently from an absolute contract of sale because full payment may be a suspensive condition rather than merely an obligation whose breach triggers Article 1191. (Lawphil)

7. Identify warranties, representations, and risk allocation

Look for statements about:

• ownership;
• authority;
• permits and licenses;
• absence of liens or encumbrances;
• condition of goods or property;
• accuracy of financial information;
• compliance with law;
• intellectual-property ownership;
• confidentiality;
• data protection;
• taxes;
• pending litigation; and
• third-party claims.

Also determine who bears losses if something happens after signing but before completion.

If a representation is important enough that you would not sign without it, it is generally safer to place it expressly in the written agreement instead of relying on a conversation, advertisement, sales presentation, or text message.

8. Examine limitation-of-liability and indemnity provisions

A contract may attempt to allocate responsibility for third-party claims, consequential losses, property damage, delays, regulatory violations, or other risks.

Ask:

• Is liability capped?
• Is the cap equal to the contract price, fees paid, insurance coverage, or another amount?
• Which claims are excluded from the cap?
• Is the indemnity one-sided?
• Who controls the defense of a third-party claim?
• Are attorney's fees included?
• Does the clause attempt to excuse conduct that cannot legally be waived?

Contractual freedom remains subject to mandatory law and public policy. (Lawphil)

9. Check whether the agreement must be written, notarized, registered, or executed in a special form

The general rule under Article 1356 is that contracts are obligatory regardless of form when their essential requisites exist. But the same provision recognizes that when the law requires a particular form for validity, enforceability, or proof, that requirement must be followed. (Lawphil)

Article 1358 identifies transactions that should appear in a public instrument, including specified transactions affecting real rights over immovable property. The consequences of failing to use a public instrument depend on the particular transaction and purpose. The Supreme Court has repeatedly explained that Article 1358's public-document requirement does not automatically mean that every non-notarized real-property agreement is void between the parties. Registration, enforceability against third persons, special statutory formalities, and the Statute of Frauds must be separately analyzed. (Lawphil)

Likewise, notarization does not magically cure an invalid transaction. The Supreme Court has emphasized that notarization is not conclusive proof that all essential elements of a contract existed or that the transaction stated in the document was genuinely intended. (Lawphil)

10. Do not overlook the Statute of Frauds

Article 1403 of the Civil Code requires specified kinds of executory agreements to be evidenced by a signed writing to be enforceable by action. These include, among others, certain agreements not to be performed within one year, promises to answer for another person's debt, leases longer than one year, and agreements for the sale of real property or an interest in it. (Lawphil)

But the Statute of Frauds is often misunderstood. It generally applies to executory agreements, not contracts that have already been totally or partially performed. The Civil Code also recognizes ratification through acceptance of benefits or failure to object to oral evidence in the circumstances contemplated by Article 1405. (Lawphil)

For an important transaction, the practical rule is simple: put the complete agreement in writing even when an oral contract might theoretically be valid.

11. Electronic contracts and electronic signatures can be legally effective

The Electronic Commerce Act recognizes electronic documents, electronic signatures, and electronic formation of contracts subject to its requirements. A contract cannot be denied validity or enforceability solely because its offer, acceptance, or other elements are expressed through electronic data messages or electronic documents. The Act, however, does not abolish special formalities that another law requires for a transaction's validity. (eLibrary)

For electronically signed agreements, preserve more than the final PDF. Where available, retain:

• the original electronic file;
• signing-platform records;
• audit trails;
• timestamps;
• authentication records;
• relevant emails and messages;
• version history; and
• evidence identifying who controlled the signing account.

These can become important if the other side later denies the signature, claims alteration, or contests the circumstances of execution.

12. Check the dispute-resolution clause before agreeing to it

Look for provisions on:

• negotiation;
• mediation;
• arbitration;
• governing law;
• exclusive or non-exclusive venue;
• service of notices;
• escalation procedures;
• construction-industry arbitration;
• allocation of arbitration costs; and
• authority to seek provisional remedies.

An arbitration clause is not decorative boilerplate. Philippine law recognizes arbitration agreements, and a valid arbitration provision may require the dispute to proceed through arbitration rather than an ordinary civil action. Special rules apply to particular disputes, including construction disputes within the jurisdiction of the Construction Industry Arbitration Commission. (Lawphil)

Never sign a contract with blanks or missing attachments

Before signing, check every page and every referenced annex, schedule, quotation, technical specification, price list, drawing, policy, or set of terms.

Do not sign if material spaces are intentionally left blank for somebody else to complete later.

If changes are handwritten, make sure the parties properly acknowledge the changes. Keep the exact final version signed by all parties.

If the agreement incorporates another document "by reference," obtain and read that document before signing. A clause referring to "standard terms," "company policies," "website terms," or a separate schedule can import substantial obligations into the contract.

What to check before trying to enforce the contract

1. Determine exactly what obligation was breached

Identify the contractual provision and ask:

• What was the other party required to do?
• When did it become due?
• Was the obligation conditional?
• Did your side satisfy its own obligations?
• Was performance partial, defective, or entirely absent?
• Has the other party expressly refused to perform?
• Has a cure period expired?

Avoid beginning with "they violated the contract." Begin with the precise obligation, due date, event, document, and act or omission constituting the supposed breach.

2. Determine the remedy you actually want

Depending on the contract and the governing law, possible remedies may include:

• collection of an unpaid amount;
• specific performance or fulfillment;
• termination or resolution;
• return of property or money;
• damages;
• enforcement of security;
• injunction or another provisional remedy; or
• a combination permitted by law.

Article 1170 makes a party liable for damages when, in performing an obligation, the party is guilty of fraud, negligence, delay, or otherwise contravenes the tenor of the obligation. Article 1191 separately addresses fulfillment or resolution in reciprocal obligations. The proper remedy therefore depends on the nature of the obligation and breach, not merely on the fact that a contract exists. (Lawphil)

3. Check whether a demand is required

Article 1169 provides the general rule that a person obliged to deliver or perform incurs delay from the time the creditor judicially or extrajudicially demands fulfillment.

Demand is not always required. The Civil Code recognizes exceptions, including when the contract or law expressly dispenses with demand, when the agreed time was a controlling motive for the contract, or when demand would be useless because performance has been rendered impossible by the obligor. (Lawphil)

Even where litigation could theoretically proceed without a demand, a properly prepared written demand is often useful because it can:

• identify the obligation;
• establish the amount claimed;
• document the breach;
• invoke contractual notice and cure provisions;
• demand performance within a defined period;
• preserve proof of receipt; and
• in appropriate cases, interrupt prescription under Article 1155.

A written demand should be drafted consistently with the contract. Sending a premature termination notice or demanding more than the contract allows can unnecessarily complicate the dispute.

4. Check prescription immediately

Do not assume that a contractual claim can be filed indefinitely.

Under the Civil Code, an action upon a written contract generally must be brought within 10 years from accrual of the right of action. An action upon an oral contract generally has a six-year period. Article 1155 provides that prescription is interrupted by filing an action in court, a written extrajudicial demand by the creditor, or a written acknowledgment of the debt by the debtor. (Lawphil)

Different periods apply to other causes of action. For example, the Civil Code provides a four-year period for an action to annul a voidable contract, with the starting point depending on whether the ground is fraud, mistake, intimidation, violence, undue influence, or incapacity. By contrast, Article 1410 states that an action or defense to declare an inexistent contract void does not prescribe. (Lawphil)

These general Civil Code periods do not mean every contract dispute follows the same deadline. Special laws, the nature of the remedy, arbitration rules, procedural rules, and the particular facts may produce a different period. If prescription is close, legal advice should be obtained promptly rather than assuming that an informal negotiation will protect the claim.

5. Check whether barangay conciliation is a precondition

Katarungang Pambarangay can be a mandatory preliminary step in disputes falling within the lupon's authority.

Under Sections 408 and 412 of the Local Government Code, covered disputes generally include those between individuals actually residing in the same city or municipality, subject to statutory exceptions. Where applicable, the required barangay proceedings ordinarily must occur before an action is filed in court or another government office for adjudication. The Code also provides exceptions allowing direct court action, including certain cases involving detention, habeas corpus, provisional remedies, or an impending statute-of-limitations bar. (Lawphil)

Do not mechanically require a barangay certificate in every contract dispute. Juridical parties, residence, location of real property, the character of the dispute, provisional relief, and the statutory exceptions can change the result.

6. Check whether small claims applies

As of the source check for this article, the Supreme Court's Rules on Expedited Procedures cover qualifying small claims of ₱1,000,000 or less in first-level courts.

The current rule covers specified money claims arising from contracts such as:

• leases;
• loans and other credit accommodations;
• services; and
• sales of personal property,

as well as qualifying enforcement of barangay settlements or arbitration awards. The procedure is intended to be simplified and expedited, and decisions in small claims cases are final, executory, and unappealable under the rule. (Supreme Court of the Philippines)

Not every contract case worth ₱1 million or less is automatically a small claim. The relief sought and nature of the underlying agreement still matter.

7. Check for arbitration before filing a lawsuit

If the agreement contains an arbitration clause, identify:

• the institution or rules;
• the seat or place of arbitration;
• the number and method of selecting arbitrators;
• required pre-arbitration negotiation or mediation;
• notice requirements;
• the scope of disputes covered; and
• whether special legislation applies.

Philippine ADR law reflects a policy favoring party autonomy and recognition of valid agreements to arbitrate. Filing directly in court without first analyzing an arbitration clause can result in procedural problems and additional expense. (Lawphil)

Evidence to preserve before a dispute gets worse

Keep original or reliable copies of:

• the signed contract and all amendments;
• annexes, schedules, specifications, quotations, and purchase orders;
• proofs of payment;
• invoices and official receipts;
• delivery receipts and acceptance certificates;
• bank records;
• photographs and videos relevant to performance;
• inspection or progress reports;
• emails, SMS messages, chat messages, and letters;
• demand letters and proof of delivery;
• notices of default, cure, cancellation, or termination;
• electronic-signature audit records;
• board resolutions, secretary's certificates, and powers of attorney;
• permits, titles, registrations, and licenses relevant to the transaction; and
• a dated chronology of important events.

Preserve original electronic records rather than relying solely on screenshots when possible. The Electronic Commerce Act recognizes electronic documents, but authenticity and integrity can become contested issues in litigation. (eLibrary)

Warning signs before signing

Consider delaying signature and obtaining legal review if:

• the other party refuses to identify the actual legal entity;
• the person signing for an owner or company cannot show authority;
• the contract contains blank spaces;
• important promises are deliberately kept outside the written contract;
• attachments are missing;
• the payment recipient is different from the contracting party without explanation;
• ownership of land, equipment, shares, or another important asset has not been verified;
• the agreement allows one party to change essential terms unilaterally;
• the default provisions are substantially harsher for only one side;
• the contract refers to policies you have not received;
• the stated price differs from the actual amount being paid;
• somebody asks you to sign an inaccurate acknowledgment or receipt;
• the document is in a language you do not understand;
• you are being pressured to sign without a reasonable opportunity to read it; or
• the transaction appears designed to conceal its real purpose.

The Civil Code specifically recognizes mistake, violence, intimidation, undue influence, and fraud as grounds that can render consent defective and a contract voidable. It also provides additional protection where a person unable to read, or unable to understand the contract's language, alleges mistake or fraud. (Lawphil)

Common mistakes when enforcing a contract

Assuming a signature makes every clause enforceable

It does not. Mandatory laws, public policy, authority, legal capacity, special formalities, and the essential requisites of contracts still matter. (Lawphil)

Treating notarization as proof that the entire transaction is valid

A notarized instrument normally has significant evidentiary consequences regarding execution and authenticity, but notarization does not conclusively establish that every contractual element is valid or that every statement in the document is true. (Lawphil)

Cancelling immediately after a minor breach

For remedies based on Article 1191, a slight or casual breach does not ordinarily justify resolution of the entire reciprocal obligation. (Lawphil)

Ignoring contractual notice and cure requirements

A party may have a good substantive claim but weaken its position by sending notice to the wrong address, using an unauthorized delivery method, skipping a cure period, or terminating before the contract permits termination.

Assuming verbal demands are enough for every purpose

An oral demand may sometimes establish default if it can be proven, but Article 1155 specifically refers to a written extrajudicial demand as an event interrupting prescription. For an important claim, preserving a written and provable demand is usually safer. (Lawphil)

Waiting because negotiations are ongoing

Settlement discussions do not automatically mean a prescriptive period has stopped. Determine separately whether an event recognized by law has interrupted prescription.

Filing in court without checking barangay conciliation or arbitration

Either mistake can lead to avoidable procedural disputes. (Lawphil)

Discarding messages after obtaining a signed contract

The parties' contemporaneous and subsequent conduct may become relevant in interpreting disputed contractual intent. Article 1371 expressly recognizes the significance of contemporaneous and subsequent acts in determining intention. (Lawphil)

When legal help is urgent

Seek prompt legal advice when:

• a prescription or contractual deadline may expire soon;
• the other party is disposing of property or appears insolvent;
• an injunction, attachment, or other provisional remedy may be necessary;
• valuable real property is being sold, mortgaged, or transferred;
• a signature, authority, or document is allegedly forged;
• corporate authority is disputed;
• fraud, intimidation, or undue influence is alleged;
• a termination notice has already been issued;
• substantial money or business operations are at risk;
• the agreement contains an arbitration clause;
• the dispute involves several related contracts;
• there are guarantors, mortgages, pledges, or other security arrangements;
• a government entity is a party;
• a foreign party, foreign law, or foreign forum is involved; or
• you have received summons, an arbitration notice, or another formal legal process.

Urgency is especially important when the remedy may depend on obtaining provisional relief or when a limitation period is approaching.

FAQ

Is an oral contract valid in the Philippines?

It can be. Philippine law generally does not require every contract to be written. But particular transactions require a certain form for validity, enforceability, proof, registration, or effect against third persons. The Statute of Frauds also makes specified executory agreements unenforceable by action unless supported by the required writing, subject to rules on ratification and performance. (Lawphil)

Does a contract have to be notarized to be valid?

Not always. Many contracts are valid without notarization. Whether notarization or a public instrument is legally necessary depends on the transaction and the purpose for which the document will be used. Lack or defect of notarization may also change the document's evidentiary status even when the underlying agreement remains valid. (Lawphil)

Can I enforce a contract signed electronically?

Potentially, yes. The Electronic Commerce Act recognizes electronic documents and electronic signatures and provides that electronic form alone is not a basis for denying contractual validity or enforceability. Applicable requirements for authentication, reliability, integrity, and any special form required by another law must still be considered. (eLibrary)

Can I cancel a contract as soon as the other party breaches it?

Not necessarily. First examine the contract's termination provisions and the nature of the breach. Where Article 1191 applies, resolution generally requires a substantial or fundamental breach rather than a slight or casual violation. Other kinds of contracts may have special cancellation rules. (Lawphil)

Must I send a demand letter before suing?

Not in every case. Article 1169 contains both the general rule on demand and recognized exceptions. The contract itself may also address whether notice or demand is required. A written demand can nevertheless be important for proving default and may interrupt prescription under Article 1155. (Lawphil)

How long do I have to sue on a written contract?

The Civil Code generally provides 10 years from accrual of the cause of action for an action upon a written contract. Different causes of action or special laws can have different periods, and certain events can interrupt prescription. (Lawphil)

What if the other person signed for somebody else without authority?

A contract entered into in another person's name without authority is generally unenforceable against the supposed principal unless properly ratified. Special rules may be stricter for particular transactions; for example, authority to sell land through an agent must be in writing. (Lawphil)

What if I already partly performed an oral agreement involving land?

Do not automatically assume the agreement is unenforceable under the Statute of Frauds. The Supreme Court has consistently explained that the Statute generally applies only to executory contracts and not agreements already partially or fully performed. The precise facts, however, remain critical, particularly where ownership, authority, registration, marital property, or third-party rights are involved. (Lawphil)

Can I use small claims to collect under a contract?

Possibly. Under the current Supreme Court rules, qualifying money claims of ₱1 million or less arising from specified contracts such as leases, loans, services, and sales of personal property may proceed under the small-claims process. Check the nature of the claim and the current Supreme Court forms and rules before filing. (Supreme Court of the Philippines)
