If someone signed a promissory note and still refuses to pay, the usual remedy in the Philippines is not to “have the debtor arrested,” but to build a clean paper trail and file the correct civil collection case. A promissory note is strong evidence because it normally shows the borrower’s written promise to pay a definite amount, on a due date, with agreed interest or penalties. The practical challenge is proving the debt, choosing the right forum, serving the debtor, and enforcing the judgment after you win.

What a Promissory Note Means Under Philippine Law

A promissory note is a written promise by one person, usually called the maker or borrower, to pay another person, usually called the payee or creditor. It may be a simple one-page document, a formal notarized instrument, or part of a loan agreement.

For collection purposes, the important parts are:

The debtor’s full name and signature
The creditor’s name
The principal amount
The due date or payment schedule
The interest rate, if any
Penalties or attorney’s fees, if agreed
Any collateral, guarantor, or surety
Proof that the money was actually released

Under the Civil Code, obligations arising from contracts have the force of law between the parties and must be complied with in good faith. A money loan is also treated as a simple loan or mutuum, where the borrower who receives money becomes bound to pay the creditor the same amount of the same kind and quality. (Lawphil)

A promissory note may also qualify as a negotiable instrument if it meets the requirements under the Negotiable Instruments Law, such as an unconditional promise to pay a sum certain in money, payable on demand or at a fixed or determinable future time. (Lawphil) But even if the note is not negotiable, it can still be useful evidence of a civil debt.

First, Check Whether the Debt Is Already Due

Before sending demands or filing a case, confirm that the obligation is already demandable.

A debt is usually due when:

The due date stated in the promissory note has passed;
An installment was missed and the note has an acceleration clause making the full balance due;
The note says “payable on demand” and you have made a demand;
The debtor violated a condition that makes the loan immediately due.

If the promissory note has no clear due date, demand becomes more important. Article 1169 of the Civil Code provides that a debtor generally incurs delay from the time the creditor judicially or extrajudicially demands performance, unless demand is unnecessary under the contract or the law. (Lawphil)

How Much Can You Collect?

You can usually claim:

Item	When recoverable
Principal	The unpaid amount stated in the promissory note or proven by release records
Interest	If expressly stipulated in writing, or legal interest after delay
Penalty charges	If stated in the note, but courts may reduce unconscionable amounts
Attorney’s fees	If agreed in the note or justified under Civil Code rules
Filing fees and costs	Usually awarded as costs, subject to the court’s decision
Damages	Only if properly alleged and proven; not automatic in every unpaid loan

Interest Must Be in Writing

Article 1956 of the Civil Code is very clear: no interest is due unless it has been expressly stipulated in writing. This means a creditor who only had a verbal agreement for “5% monthly interest” may have difficulty collecting that agreed interest if it was not written in the note, loan agreement, messages, or another written document. (Lawphil)

However, if the debtor is already in delay, Article 2209 of the Civil Code allows legal interest as damages for nonpayment of a sum of money. The current legal interest rate applied in ordinary money judgments is generally 6% per annum, following the Civil Code and Supreme Court doctrine in Nacar v. Gallery Frames. (Lawphil)

Excessive Interest Can Be Reduced

Philippine courts may reduce interest, penalties, or charges that are excessive, iniquitous, or unconscionable. The Supreme Court has repeatedly reduced very high monthly interest rates in loan cases, especially where the rate is oppressive compared with the principal and circumstances of the loan. (Lawphil)

This matters in collection cases because asking for an extreme amount can distract from an otherwise strong principal claim. A cleaner claim for principal, agreed reasonable interest, and lawful legal interest is often easier to prove.

How Long Do You Have to File a Case?

If the promissory note is in writing, an action based on that written contract must generally be filed within 10 years from the time the right of action accrues under Article 1144 of the Civil Code. For an oral contract, the prescriptive period is generally six years. (Lawphil)

The prescription period can be interrupted when:

The case is filed in court;
The creditor makes a written extrajudicial demand;
The debtor makes a written acknowledgment of the debt. (Lawphil)

This is one reason a written demand letter is useful. It does not just ask for payment; it can also help preserve the creditor’s rights if properly made before prescription expires.

Step-by-Step Guide to Collecting on an Unpaid Promissory Note

1. Gather and Organize Your Evidence

Before talking about court, organize the documents. Judges decide collection cases based on proof, not only on who sounds more believable.

Prepare:

Original promissory note
Clear photocopies of the note
Proof that the debtor received the money, such as bank deposit slips, remittance receipts, GCash or Maya screenshots, checks, acknowledgment receipts, or signed vouchers
Demand letters and proof of delivery
Text messages, emails, Messenger/Viber/WhatsApp messages acknowledging the debt
Payment history and receipts for partial payments
Computation of principal, interest, penalties, and balance
Debtor’s last known address and contact details
Copy of your valid ID
Special Power of Attorney, if someone will represent you
Board resolution or secretary’s certificate, if the creditor is a corporation or company

If the promissory note was notarized, it has stronger evidentiary value because notarization generally converts a private document into a public document, making it admissible without further proof of authenticity. (Lawphil) A note does not have to be notarized to be valid, but notarization helps prevent disputes about signatures and execution.

2. Compute the Exact Balance

Make a simple table showing:

Date	Event	Amount
Date loan was released	Principal loan	₱___
Payments received	Less payments	₱___
Written interest, if any	Add interest	₱___
Penalties, if enforceable	Add penalties	₱___
Total unpaid balance	Amount demanded	₱___

Do not inflate the claim. If the computation includes interest, identify the basis: the promissory note, written loan agreement, or legal interest after demand or default.

3. Send a Formal Demand Letter

A demand letter should be firm, factual, and easy to understand. It should state:

The date of the promissory note
The original principal amount
The due date or missed installments
Payments already made, if any
The total amount due
A deadline to pay, often 5 to 15 days
Bank or payment instructions
A statement that legal action may be filed if payment is not made

Send it through a method you can prove later:

Registered mail with registry receipt
Courier with tracking
Personal service with signed receiving copy
Email, if the debtor has used that email for the transaction
Messaging app screenshots, as supporting proof

The demand letter is not always required if the note already clearly states when payment is due, but it is still practical because it may trigger default, support legal interest, interrupt prescription if in writing, and show the court that you tried to resolve the matter before suing.

4. Check If Barangay Conciliation Is Required

For many disputes between individual residents of the same city or municipality, barangay conciliation under the Katarungang Pambarangay system may be required before filing in court. The Local Government Code requires prior confrontation before the lupon or pangkat for matters within barangay authority, and Supreme Court Circular No. 14-93 treats barangay conciliation as a pre-condition for court action when applicable. (Lawphil)

Barangay conciliation is commonly required when:

Both creditor and debtor are natural persons;
They reside in the same city or municipality;
The dispute is not excluded by law;
No corporation, partnership, government office, or urgent provisional remedy is involved.

It is commonly not required when:

One party is a corporation, partnership, or other juridical entity;
The parties reside in different cities or municipalities, subject to limited exceptions;
The action requires urgent court relief such as attachment;
The case may be barred by prescription;
The dispute falls under another agency or special law.

Barangay proceedings are meant to be quick. The punong barangay first conducts mediation; if unsuccessful, the pangkat may be constituted and given time to attempt settlement. The Local Government Code also provides that filing with the barangay can interrupt prescriptive periods, but the interruption cannot exceed 60 days. (Lawphil)

If settlement fails, get the Certificate to File Action. If you skip barangay conciliation when it is required, the case may be dismissed without prejudice or delayed.

5. Choose the Correct Court Procedure

The correct forum depends mainly on the amount of the claim and the type of relief you want.

Amount of claim	Usual route	Court
Up to ₱1,000,000, exclusive of interest and costs	Small claims	MeTC, MTCC, MTC, or MCTC
More than ₱1,000,000 up to ₱2,000,000, generally exclusive of interest, damages, attorney’s fees, litigation expenses, and costs	Civil action under summary procedure, if covered	First-level court
More than ₱2,000,000	Ordinary civil action for collection	Regional Trial Court

Small claims cover purely civil claims for payment or reimbursement of money, including money owed under a contract of loan or other credit accommodation, where the claim does not exceed ₱1,000,000 exclusive of interest and costs. (Supreme Court of the Philippines)

Civil actions within the first-level courts’ jurisdiction but outside small claims may fall under the Rules on Summary Procedure when the total claim does not exceed ₱2,000,000, subject to exclusions. (Supreme Court of the Philippines) Under Republic Act No. 11576, first-level courts generally have jurisdiction over civil actions where the amount of demand does not exceed ₱2,000,000, while RTC jurisdiction applies when the demand exceeds ₱2,000,000. (Lawphil)

Filing a Small Claims Case for an Unpaid Promissory Note

Small claims is often the most practical route for ordinary creditors because it is designed to be simpler, faster, and less expensive than a regular collection suit.

What You File

A small claims case starts by filing a Statement of Claim with verification and certification against forum shopping, plus supporting documents. The Supreme Court rules require certified photocopies of the actionable documents, affidavits of witnesses, and other evidence to be attached because evidence not submitted with the Statement of Claim may not be allowed later unless there is good cause. (Supreme Court of the Philippines)

Attach:

Promissory note
Demand letter
Proof of delivery of demand
Proof of release of money
Computation of balance
Affidavit explaining the transaction
Barangay Certificate to File Action, if required
SPA, board resolution, or secretary’s certificate, if applicable

Court personnel are required to provide forms and information about small claims coverage, requirements, and procedure. (Supreme Court of the Philippines)

Can a Lawyer Appear in Small Claims?

No attorney may appear for or represent a party at the small claims hearing, unless the attorney is the plaintiff or defendant. Parties must personally appear, and representatives must be properly authorized. (Supreme Court of the Philippines)

You may prepare with legal help before the hearing, but the hearing itself is designed for the parties to present their documents and explanation directly to the judge.

What Happens After Filing

The court issues summons and notice of hearing. Under the Rules on Small Claims, the notice of hearing should set the hearing not more than 30 calendar days from filing, or not more than 60 calendar days if one defendant resides or holds business outside the judicial region. Summons and notice of hearing must be issued within 24 hours from receipt of the Statement of Claim and served by the sheriff or proper court officer within 10 calendar days from issuance. (Supreme Court of the Philippines)

The defendant must file a verified Response within a non-extendible period of 10 calendar days from receipt of summons, with supporting documents and affidavits attached. (Supreme Court of the Philippines)

At the hearing, the judge first tries to bring the parties to an amicable settlement. If settlement fails, the court hears the case informally and expeditiously, then renders judgment within 24 hours from termination of the hearing. (Supreme Court of the Philippines)

A small claims decision is final, executory, and unappealable. Execution may issue upon an ex parte motion of the winning party once the decision is rendered and proof of receipt is on record, except for decisions based on compromise. (Supreme Court of the Philippines)

Filing Fees and Practical Costs

Filing fees are assessed by the Clerk of Court based on the Rules of Court and current OCA issuances. In 2025, the Office of the Court Administrator issued revised guidelines for legal fees in small claims cases. Plaintiffs engaged in the business of lending, banking, or similar activities are assessed the same filing and other legal fees applicable to regular cases; a ₱500 mediation fee is collected from such plaintiffs.

For example, the OCA’s 2025 sample computation for a ₱900,000 small claims case showed filing fees of ₱15,000, summons fee of ₱200, Legal Research Fund fee of ₱150, Victim’s Compensation Fund fee of ₱5, and Sheriff’s Trust Fund fee of ₱1,000, with an additional ₱500 mediation fee if the plaintiff is registered as engaged in lending, banking, or similar activities.

Always ask the Clerk of Court for the current computation because fees may depend on the claim amount, plaintiff type, and current circulars.

What If the Debtor Is Abroad or You Are Abroad?

If the creditor is overseas, a representative in the Philippines can usually act through a Special Power of Attorney. If the SPA is executed abroad, it is commonly notarized at the Philippine Embassy or Consulate, or apostilled by the competent authority in an Apostille Convention country, depending on where it is signed and how it will be used. DFA posts commonly state that SPAs executed abroad may be consularized or apostilled, subject to post-specific requirements. (Philippine Embassy in New Delhi)

If the debtor is abroad, service of summons becomes a major bottleneck. Under the Rules on Expedited Procedures, service made pursuant to the Hague Convention on Service Abroad in civil or commercial matters is valid, and the period to answer begins from receipt of the served document. (Supreme Court of the Philippines) In practice, this can make the case slower and more expensive, especially if the debtor’s exact foreign address is unknown.

If the debtor still has assets, employment, bank accounts, business interests, or property in the Philippines, enforcement may still be practical after judgment.

How You Actually Collect After Winning

Winning the case is not the same as receiving money. If the debtor does not voluntarily pay, the next step is execution.

In money judgments, the sheriff may demand payment from the judgment debtor. If the debtor cannot or will not pay, the sheriff may levy on property that can legally be sold, usually starting with personal property before real property when appropriate. Debts, credits, bank deposits, shares, and other property interests may also be reached through garnishment or levy, subject to procedural rules and exemptions. (Lawphil)

Common enforcement options include:

Garnishment of bank accounts, if located
Levy and sale of personal property
Levy on real property
Garnishment of receivables owed to the debtor
Examination proceedings to locate assets, when available

The practical problem is asset discovery. If the debtor has no visible assets, no bank account you can identify, no real property, and no steady income, collection may still be difficult even after judgment.

When Nonpayment May Become a Criminal Issue

A simple failure to pay a loan is usually a civil matter. The Supreme Court has held that a borrower is not generally liable for estafa through misappropriation merely because he or she fails to repay a loan; the liability is ordinarily civil. Estafa may exist if the borrower used fraud or deceit to induce the creditor to part with money at the start of the transaction. (Lawphil)

A different issue arises if the debtor issued a check that bounced. Batas Pambansa Blg. 22 penalizes the making, drawing, or issuance of a check without sufficient funds or credit. (Lawphil) But BP 22 has its own requirements, including proper notice of dishonor, and should not be confused with a promissory note case. The civil aspect of a BP 22 violation may also be handled under expedited procedure rules when no criminal action has been filed. (Lawphil)

Common Mistakes Creditors Make

Filing Too Early

If the note is not yet due, or if it is payable on demand and no demand has been made, the debtor may argue that the case is premature.

Relying Only on the Promissory Note

A promissory note is powerful, but courts may still ask whether the loan proceeds were actually delivered. Keep proof of release.

Claiming Verbal Interest

Interest on a loan must be in writing. If the interest was not written, focus on principal and legal interest after demand or default.

Ignoring Barangay Conciliation

When barangay conciliation is required, skipping it can delay the case. Get the Certificate to File Action before filing.

Filing in the Wrong Court

A ₱700,000 promissory note collection case generally belongs in small claims, while a ₱1.5 million claim may fall under summary procedure, and a claim above ₱2 million generally goes to the RTC. Filing in the wrong court can waste time and filing fees.

Threatening Criminal Charges for a Pure Debt

Demand letters should not casually threaten arrest or estafa if the facts only show nonpayment. If there was no deceit at the start, the usual remedy is civil collection.

Forgetting Enforcement

Before spending money on litigation, think about collectability. A debtor with employment, bank accounts, vehicles, business receivables, or real property is different from a debtor with no known assets.

Practical Timeline

Stage	Typical timeframe
Demand letter	5 to 15 days for payment deadline
Barangay conciliation, if required	Often several weeks; prescription interruption is limited by law
Small claims filing to hearing	Hearing generally set within 30 days, or up to 60 days if a defendant is outside the judicial region
Defendant’s small claims response	10 calendar days from receipt of summons
Small claims decision	Within 24 hours from termination of hearing
Execution	Depends on debtor’s assets, sheriff availability, and bank/property responses

Actual timelines vary by court workload, success of service of summons, accuracy of the debtor’s address, postponements, and whether the debtor has reachable assets.

Frequently Asked Questions

Can I collect on a promissory note without a lawyer in the Philippines?

Yes, if the claim qualifies as a small claims case. Lawyers are not allowed to represent parties at the small claims hearing, although you may prepare your documents beforehand. For larger or more complex collection suits, formal pleadings and procedural rules make legal representation more common.

Is a notarized promissory note required?

No. A promissory note can be valid even if not notarized, as long as it proves a real obligation. Notarization helps because a notarized document is treated as a public document and generally enjoys stronger evidentiary value.

What if the debtor says the signature is fake?

You will need supporting evidence, such as the original note, witnesses, messages, IDs used during signing, notarization details, payment history, or admissions by the debtor. If forgery is seriously raised, the case may become more complicated than a straightforward small claims dispute.

Can I file estafa for an unpaid promissory note?

Not automatically. Mere failure to pay a loan is normally civil. Estafa may be considered only if there was fraud or deceit at the beginning, such as false representations that induced you to lend the money.

How long do I have to sue on a promissory note?

For a written promissory note, the general prescriptive period is 10 years from the time the right of action accrues. Written demand, filing in court, or written acknowledgment of the debt can interrupt prescription.

Can I collect interest if the promissory note does not mention interest?

You generally cannot collect agreed loan interest unless it was expressly stipulated in writing. You may still claim legal interest as damages once the debtor is in delay, depending on the facts and the court’s ruling.

What if the debtor made partial payments?

Partial payments reduce the balance and can also help prove that the debtor acknowledged the loan. Keep receipts and update the computation carefully. If there are several debts, specify which debt each payment applies to.

Can I garnish the debtor’s salary or bank account immediately?

Usually not before judgment, unless a proper provisional remedy is available in a regular case. Small claims excludes actions coupled with provisional remedies. After judgment, enforcement may include garnishment or levy through the sheriff, subject to the Rules of Court.

What if the debtor is a foreigner?

A foreign debtor can still be sued in the Philippines if Philippine courts have jurisdiction and summons can be properly served. The harder questions are service of summons and enforcement. If the foreigner has assets or business interests in the Philippines, collection may be more practical.

What if I am abroad and cannot attend personally?

You may execute a Special Power of Attorney authorizing someone in the Philippines to act for you. If signed abroad, the SPA usually needs consular notarization or apostille, depending on the country and the receiving court’s requirements.
