If you require legal advice tailored to your specific situation, it is best to consult a qualified attorney in the Philippines.


I. Introduction

In the Philippines, a Promissory Note (PN) and a Deed of Sale are two different but sometimes interrelated legal instruments. A promissory note is a written and signed promise to pay a certain sum of money to a specific person or bearer at a future date or on demand. A deed of sale (often referring to a Deed of Absolute Sale for real property or personal property) is a formal contract whereby one party (the seller) transfers ownership of a property to another party (the buyer) for a price certain in money or its equivalent.

Questions often arise regarding the validity and effect of a promissory note when there is already a deed of sale in place. For instance:

  • Can a buyer still be required to pay under a promissory note even if the deed of sale has been executed?
  • Does the deed of sale automatically negate or supersede the promissory note?
  • What if the deed of sale indicates full payment, but there is still an unpaid balance evidenced by a promissory note?

Below is a comprehensive discussion of all major considerations under Philippine law on the topic of the “Validity of a Promissory Note After a Deed of Sale.”


II. Legal Framework for Promissory Notes in the Philippines

  1. Negotiable Instruments Law (Act No. 2031)

    • A promissory note (PN) typically falls under the purview of the Negotiable Instruments Law if it meets certain requirements (e.g., it is in writing and signed by the maker, contains an unconditional promise to pay a sum certain, payable on demand or at a fixed or determinable future time, and is payable to order or bearer).
    • Even if a promissory note does not strictly meet all the conditions of a negotiable instrument, it may still be valid as a common-law instrument (i.e., a valid contract evidencing indebtedness).
  2. Civil Code of the Philippines

    • Obligations and Contracts (Articles 1156–1304): These provisions govern how obligations are formed, extinguished, or enforced.
    • Requisites of Contracts: For a contract (including a promissory note) to be valid, it must have consent, object, and cause (Article 1318).
    • Proof of Debt: A written promise to pay creates a binding obligation between the parties, provided the essential requisites of consent, object, and consideration are present.

Under these laws, as long as the promissory note has all the essential elements (lawful subject matter, consideration, consent, and compliance with any formalities), it remains valid and enforceable.


III. Legal Framework for Deeds of Sale in the Philippines

  1. Nature of a Deed of Sale

    • A deed of sale is a formal contract wherein one party conveys ownership of property to another for a price.
    • Upon execution of a valid deed of sale, ownership is generally transferred to the buyer (assuming all legal requirements and formalities, like notarization, payment of taxes, registration in the case of real property, etc., are complied with).
  2. Absolute vs. Conditional Sale

    • A Deed of Absolute Sale typically indicates full and final payment. The usual language states that the purchase price is paid and acknowledged by the seller, and that absolute ownership is henceforth transferred.
    • A Deed of Conditional Sale or a Contract to Sell may indicate that the title remains with the seller until full payment, or that some conditions must be fulfilled before ownership transfers.
    • Even an “absolute” deed can include stipulations about outstanding balances or payment terms if the parties so agree.
  3. Integration with Other Contracts

    • A deed of sale can sometimes be executed together with a promissory note, especially if the buyer still owes part of the purchase price.
    • The purchase price stated in the deed of sale may be partially or entirely covered by a promissory note.

IV. Relationship Between a Promissory Note and a Deed of Sale

  1. Different Legal Instruments

    • A promissory note and a deed of sale serve different functions:
      • Deed of Sale: Conveys ownership.
      • Promissory Note: Evidences a debt or obligation to pay.
  2. Continuing Obligation

    • Even after a deed of sale is executed, the obligation to pay as stated in a valid promissory note can remain enforceable. In other words, the buyer who has signed a promissory note still owes the debt until it is fully paid.
    • The fact that a deed of sale has been notarized or registered does not by itself extinguish the obligation on the promissory note.
  3. “Full Payment” Clauses in the Deed of Sale

    • It is common practice for a deed of absolute sale to recite that the seller has received full payment from the buyer. However, sometimes the buyer and seller have a side agreement (e.g., a promissory note) indicating that some balance remains due.
    • Philippine courts generally allow evidence of a side agreement or a promissory note to prove that the stated “full payment” in the deed of sale was not truly received, provided such side agreement is valid and not contrary to law or public policy.
  4. Possible Conflicts

    • If the deed of sale explicitly states that “payment has been received in full and no balance remains,” while a separate promissory note indicates an outstanding balance, courts will look into the true intent of the parties.
    • In many cases, parol evidence (oral or extrinsic evidence) may be admitted to clarify the terms of the real transaction, especially if there is an allegation of mistake or if the deed of sale’s acknowledgment of payment was intended merely for formality.
  5. Extinguishment of Obligation

    • A promissory note obligation may be extinguished by:

      1. Payment – Full settlement of the amount due.
      2. Condonation or Waiver – If the seller-creditor formally waives the debt.
      3. Merger of Rights – If the person owed the money (the seller) and the debtor become the same person, under certain circumstances.
      4. Novation – If the original contract is superseded by a new agreement that expressly extinguishes the old one.
    • Executing a deed of sale does not automatically extinguish the obligation under a promissory note unless the deed expressly states that the promissory note is canceled or the obligation is waived.


V. When Is the Promissory Note Invalid or Unenforceable?

Even after a deed of sale, certain situations can render a promissory note invalid or unenforceable:

  1. Lack of Consideration

    • If it is proven that there was no valid consideration for the promissory note (e.g., the amount promised to be paid had already been paid in full), the promissory note would be rendered invalid.
  2. Defects in Consent

    • If the maker of the promissory note can prove that it was signed under duress, intimidation, fraud, or mistake, the note may be declared invalid.
  3. Illegal or Immoral Cause

    • If the promissory note is executed for an illegal purpose, it is void. This is extremely rare in typical sale transactions, but it remains a legal principle.
  4. Prescription

    • Under Philippine law, actions to enforce written contracts (including promissory notes) generally prescribe after ten (10) years from the time the right of action accrues (Article 1144, Civil Code). If the seller-creditor fails to file a case to collect within that prescriptive period, the right to enforce the promissory note may be lost.

VI. Practical Considerations

  1. Documentation Alignment

    • To avoid future disputes, the deed of sale and any related promissory note(s) should be drafted consistently, clearly indicating:
      • The total purchase price.
      • How much was paid outright at the execution of the deed.
      • How any remaining balance will be paid (i.e., through the promissory note).
    • This clarity helps ensure that both parties’ rights and obligations are clearly set forth.
  2. Notarization and Witnesses

    • While a promissory note is not required by law to be notarized, having it notarized (or at least witnessed) can strengthen its enforceability and evidentiary value in court.
  3. Registration

    • For real property, the deed of sale should be recorded with the Registry of Deeds to perfect the transfer of ownership. However, promissory notes are not registered with the government. They remain personal obligations of the debtor.
  4. Partial Payments

    • If partial payments are made under the promissory note, it is vital for the debtor to secure written acknowledgments of these payments to avoid disputes over how much has been paid.
    • From the creditor’s perspective, consistent documentation of payments helps track the remaining balance accurately.
  5. Acceleration Clauses and Default

    • Some promissory notes contain acceleration clauses stating that if the buyer fails to pay one installment, the entire remaining balance becomes due and demandable. This can have implications for the buyer’s ownership rights if the sale is conditional or there is a separate mortgage or security agreement.

VII. Frequently Asked Questions

  1. Does a Deed of Sale automatically cancel the promissory note?

    • No. A deed of sale and a promissory note are two distinct contracts. Unless the deed of sale expressly provides that the debt evidenced by the promissory note is extinguished or waived, the note remains valid.
  2. What if the deed of sale states “full payment received,” but I still have an unpaid balance under a promissory note?

    • In practice, the deed of absolute sale may state “full payment” to facilitate paperwork and avoid taxes/fees on subsequent installments. However, if there is a separate valid promissory note, the debtor is still bound to pay. Courts will consider the real intent of the parties; the note’s existence typically proves that payment was not yet truly complete.
  3. Can I sell a property even if there is a remaining balance evidenced by a promissory note?

    • If the deed of sale was already executed in favor of the buyer, that buyer generally owns the property—subject to any lawful lien or contract the parties may have agreed on (e.g., a mortgage to secure the promissory note). If no security interest (like a mortgage) is established, the creditor’s remedy is to file a collection suit, not necessarily to reclaim the property.
  4. Is it better to reflect the unpaid balance in the deed of sale itself?

    • From a documentation standpoint, it is often clearer to indicate the unpaid balance directly in the deed (e.g., “partial payment in the amount of PHP X has been made, leaving a balance of PHP Y”) and attach the promissory note as an annex. This reduces confusion and helps align the documents.
  5. What happens if I do not pay the promissory note on time?

    • The seller-creditor can demand payment, and if you fail to respond, may file a civil action for collection of sum of money.
    • If the deed of sale is conditional, the seller might have contractual remedies—potentially seeking rescission of the sale if such right is contractually reserved. But for a deed of absolute sale with no such reservation, the remedy is typically collection, not rescission.

VIII. Conclusion

A promissory note remains an independent and enforceable obligation even after a deed of sale has been executed, provided the note is valid in itself and the parties intended for the obligation to remain. The deed of sale, on its own, does not extinguish the debt reflected in the note unless it explicitly states that the obligation is waived or canceled.

From a practical standpoint, clarity in drafting and consistency between documents are crucial. When entering into a transaction involving both a deed of sale and a promissory note:

  1. Make sure each document is clear on the purchase price, payment schedule, and any balance due.
  2. Understand that “full payment received” in the deed of sale may not bar enforcement of the promissory note if it can be shown that the parties intended for a remaining balance to be paid.
  3. Keep a paper trail of all partial payments and always seek written acknowledgment of payment.
  4. In case of disputes, courts will look to the true intent of the parties and the totality of the evidence—so well-drafted and properly executed documents are your best protection.

When in doubt about your rights or obligations, always consult a qualified legal professional who can provide advice specific to your circumstances under Philippine law.
