Is a Contract Legally Binding? Philippine Review Checklist

Short answer: A Philippine contract is binding when three essentials are present: consent of the parties, a lawful and determinate object, and a lawful cause (Civil Code, Art. 1318). Most contracts bind in whatever form they are made, oral or written (Art. 1356). To check a specific contract, review it in order: (1) did both sides actually agree; (2) did each have the capacity and authority to agree; (3) was consent free of mistake, violence, intimidation, undue influence or fraud; (4) is the object lawful, possible and determinate; (5) is the cause lawful; (6) does the law require a particular form or a writing; and (7) does any rule make it rescissible, voidable, unenforceable or void. The answer at each step tells you which of five categories the contract falls into and what you can do about it.

For the requisites themselves, see what makes a contract valid. For how agreement is formed, see offer, acceptance and consent. This page is the review process.

The seven-step review

Step	Question	If the answer is no
1. Agreement	Was there a certain offer and an absolute acceptance on the object and the cause (Art. 1319)?	No contract was perfected. A qualified acceptance is only a counter-offer
2. Capacity	Was each party of age and of sound mind, and not otherwise incapacitated (Art. 1327)?	Voidable if one party lacked capacity (Art. 1390); unenforceable if both did (Art. 1403(3)). See limited capacity
3. Authority	If someone signed for another person or a company, did they have authority, in writing where required?	Unenforceable against the principal unless ratified (Art. 1403(1)); a sale of land through an agent without written authority is void (Art. 1874)
4. Free consent	Was consent given without mistake, violence, intimidation, undue influence or fraud (Art. 1330)?	Voidable; the action to annul must be brought within four years, counted from discovery of the mistake or fraud, or from the time intimidation, violence or undue influence ceases (Art. 1391)
5. Object	Is the object within the commerce of men, possible, and determinate or determinable (Arts. 1347 to 1349)?	Void (Art. 1409)
6. Cause	Is there a cause, and is it lawful and not contrary to morals, good customs, public order or public policy (Arts. 1350 to 1353)?	Void if there is no cause or the cause is unlawful (Art. 1352)
7. Form	Does the law require a particular form for validity, enforceability or registration?	Void if the form is required for validity; unenforceable if a writing is required under the Statute of Frauds; still binding but not registrable if only convenience form is missing

Step 7 in detail: when form matters

Kind of form rule	Examples	Effect if missing
Form for validity	Donation of land in a public instrument (Art. 749); stipulation of interest on a loan in writing (Art. 1956); sale of land through an agent with written authority (Art. 1874)	The contract or the stipulation is void
Writing for enforceability (Statute of Frauds)	Sale of real property or an interest in it; lease of more than one year; agreement not to be performed within a year; guaranty; sale of goods worth ₱500 or more (Art. 1403(2))	Unenforceable by court action unless ratified, by failure to object to oral evidence of the contract or by accepting benefits under it (Art. 1405). See Statute of Frauds
Form for convenience or registration	Acts transmitting real rights over immovables should be in a public instrument (Art. 1358)	Still binding between the parties, who may compel each other to execute the proper document (Art. 1357)

Notarization is usually not needed for a contract to bind the parties; it matters for registration, for binding third persons and as evidence. A contract is not denied validity or enforceability solely because it was made through electronic messages or documents, such as text, chat or email (Electronic Commerce Act, RA 8792, Sec. 16(1)); it still has to be proved, and any special form the law requires still applies. See are oral agreements binding.

Also check: is it rescissible?

A contract that passes every step can still be rescinded in the cases listed in Article 1381, such as contracts by guardians or representatives that cause lesion of more than one-fourth of the value, and contracts made in fraud of creditors. Rescission is a subsidiary remedy, available only when the injured party has no other legal means to obtain reparation (Art. 1383), and it must be sought within four years (Art. 1389).

The verdict: what kind of contract is it?

Verdict	Binding now?	Can it be fixed?	Your next step
Valid	Yes	Not needed	Perform, or enforce it. See breach of contract
Rescissible	Yes, until rescinded	Not applicable	Sue for rescission within four years if you are the injured party or a defrauded creditor
Voidable	Yes, until annulled	Yes, by ratification (Art. 1392)	Sue to annul within four years, or confirm it
Unenforceable	Cannot be enforced in court	Yes, by ratification or, under the Statute of Frauds, by performance	Get a writing signed or the contract ratified; if benefits were already accepted, the Statute of Frauds defense may be lost (Art. 1405)
Void	No, from the start	No; cannot be ratified, and the action to declare it void does not prescribe (Arts. 1409 and 1410)	Treat it as no contract; recover what was given if the law allows

Practical red flags in a written contract

The person signing is not the person named, or signs for a company without a board resolution or secretary’s certificate.
The price, object or main obligation is left blank or “to be agreed”.
Interest is charged but not stated in writing.
A married seller signs alone for property acquired during the marriage.
The contract waives rights the law makes non-waivable, or requires an illegal act.
Key pages are unsigned or uninitialed, or the copies held by each party differ.

Your options and what to do next

Once you know the verdict, the next step depends on whether you want to keep the contract or get out of it. A valid contract has the force of law between the parties and must be complied with in good faith (Art. 1159).

Your goal	Remedy	Time limit
Enforce a valid contract the other side broke	Written demand, then an action for performance or damages	10 years if written, 6 years if oral (Arts. 1144 and 1145)
Get out of a contract signed through fraud, mistake or pressure	Action to annul the voidable contract (Art. 1390)	4 years from discovery or from when the pressure ceased (Art. 1391)
Undo a contract that is void	Action or defense to declare it void	None; it does not prescribe (Art. 1410)
Fix a writing that does not reflect what was agreed	Reformation of the instrument (Art. 1359)	No single period verified here; act promptly once you notice the error
Make an oral deal enforceable	Put it in writing, or compel the proper form once the contract is perfected (Art. 1357)	Not fixed; best done before any dispute arises

Where to go. Start with a written demand that states the defect or breach and what you want done. See when a demand letter is required. If both parties are individuals living in the same city or municipality, barangay conciliation is generally required before a court case (Local Government Code, Secs. 408 and 412). A money claim may fit the small claims procedure; annulment, reformation and larger claims go to the regular courts. If you cannot afford a lawyer, ask the Public Attorney’s Office whether you qualify for free assistance.

What to bring: the signed contract and every version exchanged, proof of each signatory’s identity and authority (special power of attorney, board resolution or secretary’s certificate), receipts and proof of payment or delivery, and the messages showing how the deal was negotiated.

First action: run the seven-step review above on your copy, note the first step that fails, and write down the date you discovered the problem. That date can start the four-year clock for annulment.

Frequently asked questions

Is a contract binding if I did not read it before signing?

Generally yes. Failure to read is not a defense by itself. It may matter only if the other party misled you about the contents, or if you could not read the language and the terms were not explained to you, which can shift the burden to the other party to show you understood them (Art. 1332).

Can I cancel a contract I just signed?

Not unilaterally, unless the contract or a special law gives a cooling-off right or the other party breaches. See cancelling a contract after signing.
