What Is an Acknowledgment of Debt?
An Acknowledgment of Debt (AOD) is a notarial instrument in which a debtor formally declares under oath — before a notary public — that he or she owes a specific sum of money to a creditor, including the repayment terms and any applicable interest. Because it is executed before a notary, it constitutes a public document under the Rules of Court, making it one of the strongest forms of written evidence of a money obligation in Philippine courts.
Unlike a promissory note, which is a negotiable instrument that can be transferred to third parties, an AOD is a sworn declaration tied to the specific parties. It is commonly used for personal loans, cash advances between businesses, and any arrangement where the creditor needs maximum evidentiary protection.
When Do You Need an Acknowledgment of Debt?
- Personal cash loans — between family members, friends, or private individuals where the lender wants notarized proof
- Business cash advances — company-to-company or company-to-employee loans that require a formal record
- Restructured debts — converting an existing informal obligation into a formal, notarized instrument
- Loans with a co-maker — when a solidary guarantor will also sign, binding both the debtor and co-maker to the obligation
- Pre-litigation documentation — when the creditor wants to strengthen their position before sending a demand letter or filing a collection case
What Must Be Included
- Debtor's full name, civil status, and address — the party acknowledging the debt
- Creditor's full name, civil status, and address — the party to whom the debt is owed
- Principal amount — stated in both words and figures (e.g., "Fifty Thousand Pesos (PHP 50,000.00)")
- Basis of debt — optional but recommended (e.g., "cash loan extended on May 1, 2026")
- Interest clause — rate per month or per annum; omit or state "non-interest-bearing" if no interest applies
- Payment terms — a specific due date or a payment period from execution
- Default clause — stating that failure to pay on the due date constitutes default without further demand, and the full balance becomes immediately due
- Co-maker clause — if applicable, with solidary liability language and the co-maker's signature block
- Testimonium clause and signature — debtor (and co-maker) signs before witnesses
- Acknowledgment block — venue, appearing parties table with government IDs, and the notary's closing
- Notarial register — Doc. No., Page No., Book No., Series of
