Is a Promissory Note Valid Without a Notary?
Quick answer
Yes, a promissory note can be valid and binding even if it is not notarized. Under the Civil Code, contracts bind the parties "in whatever form" they were made, as long as the essential requisites are present. The Code says contracts involving more than ₱500 must appear in writing, and a private writing signed by the borrower meets that rule. The Civil Code articles on the form of contracts do not require a simple loan of money to be notarized.
Does a promissory note need to be notarized?
The Civil Code does not list a simple loan of money among the contracts that must be in a public document. Article 1356 sets the general rule:
Contracts shall be obligatory, in whatever form they may have been entered into, provided all the essential requisites for their validity are present.
The essential requisites are in Article 1318: consent of the parties, an object certain, and a cause of the obligation. Article 1356 does not add notarization to that list.
Article 1358 lists the contracts that "must appear in a public document". They are acts and contracts that create, transfer, change or end real rights over immovable property such as land; the cession, repudiation or renunciation of hereditary rights or of rights in the conjugal partnership of gains; certain powers to administer property; and the cession of actions or rights that come from an act in a public document. A loan of money is not on that list.
For everything else, the last paragraph of Article 1358 applies:
All other contracts where the amount involved exceeds five hundred pesos must appear in writing, even a private one.
"Even a private one" means a document signed by the parties without a notary is enough for this rule. The ₱500 figure is the original 1949 amount in the Code. Article 1357 adds that once the contract is perfected, the parties "may compel each other to observe that form": the rule on writing does not stop the contract from existing.
This page does not cover how a notarized document is treated as evidence in court, or notarial fees. Those are separate questions.
Is a handwritten or simple receipt enough?
It can prove the loan. In Spouses Abella v. Spouses Abella (2015), the borrowers signed a short acknowledgment receipt for ₱500,000, "payable within one (1) year from date hereof with interest". The Supreme Court treated this receipt as proof of a simple loan with interest agreed in writing, and applied the legal rate to it. On the numbers, the Court found that the borrowers had already paid the loan and its interest in full, and ordered the lenders to return a small overpayment. The decision did not discuss notarization.
Under Article 1953, the person who receives a loan of money "is bound to pay to the creditor an equal amount of the same kind and quality". The note or receipt is how the lender proves that obligation.
What is a negotiable promissory note?
The Negotiable Instruments Law (Act No. 2031) uses the term in a narrower sense. Under Section 184, a negotiable promissory note is an unconditional promise in writing, signed by the maker, to pay a sum certain in money on demand or at a fixed or determinable future time, to order or to bearer. Section 1 lists the same requirements.
The Negotiable Instruments Law has its own rules for these notes. A personal note is not negotiable if it does not say "to order" or "to bearer", or if the promise is conditional. That does not make them worthless. A non-negotiable note can still be a valid written loan contract under the Civil Code.
What should the note say about interest?
If interest was agreed, it must be written down. Article 1956 says:
No interest shall be due unless it has been expressly stipulated in writing.
If the note says "with interest" but gives no rate, the Court in Abella applied the legal rate in force when the agreement was signed. For an agreement signed from July 1, 2013, the legal rate is 6% a year. See What is the legal interest rate in the Philippines? and Is 5% monthly interest legal?
How long can the lender sue on a promissory note?
A note is a written contract. Under Article 1144, an action upon a written contract must be brought within ten years from the time the right of action accrues. A case filed in court, a written demand by the creditor, or a written acknowledgment of the debt by the debtor interrupts the period (Article 1155). See How many years can you collect a debt?
If there is no paper at all, the period for an oral contract is six years. See Is a verbal agreement binding?
How does this work in real life?
These are made-up examples to show how the rules work. They are not advice for any real case.
Nina lends ₱15,000 to Paolo. Paolo writes and signs: "I promise to pay Nina ₱15,000 on June 30." There is no notary. It is a written loan contract (Articles 1356 and 1358). If Paolo does not pay, Nina has ten years from the due date to sue on it (Article 1144).
The same note says "with interest" but no rate. Interest was agreed in writing, but without a rate, so under Abella the legal rate at the time of signing applies.
Ramon signs a note that says: "I will pay Lito ₱40,000 if my business earns a profit this year." Because the promise depends on a condition, it is not a negotiable promissory note under Section 184. Whether Lito can collect depends on whether the condition happens and on the Civil Code rules on conditional obligations.
Joy lent ₱6,000 to her cousin and kept only a chat message saying "thanks for the ₱6,000, I'll pay next month". Whether that message is enough proof is a question of evidence that this page does not cover.
When do you need a lawyer?
Talk to a lawyer if you are about to lend or borrow a large amount, if the note involves land, a mortgage or a guarantor, or if you want to file a case on a note. A lawyer can also explain when notarization is useful for your document. If you cannot afford a lawyer, see Free legal help in the Philippines.

Frequently asked questions
Is a promissory note valid without a notary in the Philippines?
It can be. Article 1356 of the Civil Code says contracts are obligatory in whatever form they were entered into, as long as the essential requisites are present. A simple loan of money is not among the contracts that Article 1358 says must appear in a public document.
Does a promissory note have to be in writing?
For amounts above ₱500, Article 1358 says the contract must appear in writing, even a private one. A handwritten note signed by the borrower is a private writing. Under Article 1357, once the contract is perfected, the parties can compel each other to put it in that form.
Is an acknowledgment receipt the same as a promissory note?
Not exactly, but it can prove a loan. In Spouses Abella v. Spouses Abella (2015), the Supreme Court treated a short signed receipt for money, payable in one year with interest, as proof of a simple loan and applied the legal interest rate to it.
What if the promissory note does not state the interest rate?
Interest is due only if it is expressly agreed in writing (Article 1956). If the note says with interest but gives no rate, the Court in Abella applied the legal rate in force when the agreement was signed.
How long can the lender sue on a promissory note?
An action upon a written contract must be brought within ten years from the time the right of action accrues (Article 1144). A written demand or a written acknowledgment of the debt interrupts the period (Article 1155).
