If a co-maker refuses to pay a loan in the Philippines, the first thing to do is not to argue about fairness, friendship, or family promises. Start with the document. In Philippine loan practice, the word “co-maker” can mean different things depending on the exact wording of the promissory note, loan agreement, or co-maker’s undertaking. A co-maker may be a solidary debtor who can be made to pay the whole loan, a surety who directly answers for the debt, a guarantor whose liability may be more limited, or merely a joint debtor liable only for a share. The correct next step depends on which one applies. (Lawphil)

What Does a Co-Maker Mean in Philippine Loan Law?

A co-maker is usually someone who signs a loan document together with the borrower to strengthen the creditor’s chance of collection. Banks, cooperatives, lending companies, informal lenders, and even relatives often require a co-maker when the main borrower has weak income, poor credit history, no collateral, or is working abroad.

But “co-maker” is not magic wording by itself. What matters is the obligation written in the contract.

If the co-maker signed “jointly and severally” or “solidarily”

This is the most serious type of co-maker liability.

Under Article 1216 of the Civil Code, a creditor may proceed against any one of the solidary debtors, some of them, or all of them at the same time until the debt is fully collected. Article 1207 also says solidarity is not presumed; it must be expressly stated, required by law, or required by the nature of the obligation. (Lawphil)

In plain English: if the promissory note says “jointly and severally,” “solidarily,” “in solidum,” or “I/we promise to pay,” the creditor may usually demand the entire unpaid balance from the co-maker, even if the co-maker did not personally receive the loan proceeds.

The Supreme Court applied this principle in Inciong v. Court of Appeals, where the promissory note stated that the signatories were jointly and severally liable. The Court held that any one, some, or all of them could be proceeded against for the entire obligation. (Lawphil)

If the co-maker signed only as a guarantor

A guarantor is different. Under Article 2047 of the Civil Code, a guarantor binds himself or herself to fulfill the obligation only if the principal debtor fails to do so. If the person binds himself or herself solidarily with the principal debtor, the contract is treated as suretyship. (Lawphil)

This distinction matters because a guarantor may have defenses that a solidary co-maker does not always have. A surety, on the other hand, is closer to a solidary debtor because the surety directly answers for the obligation.

If the document does not clearly say the co-maker is solidarily liable

If the contract merely names several borrowers or co-makers but does not clearly state solidary liability, the debt is generally presumed joint. Article 1208 provides that if solidarity does not appear from the law, the nature of the obligation, or the wording of the obligation, the debt is divided into as many shares as there are debtors. (Lawphil)

This is why the exact language of the promissory note matters more than what the borrower and co-maker verbally understood.

Who Are You in the Situation?

The best remedy depends on your role.

Your situation	Practical meaning	Usual next step
You are the creditor or lender	You want the co-maker to pay because the borrower defaulted	Review the contract, send a written demand, consider barangay conciliation, small claims, or civil action
You are the principal borrower	The lender is chasing you, but the co-maker promised to help pay	Check if you have a separate written agreement with the co-maker; the lender may still collect from you
You are the co-maker being collected from	You may be liable depending on whether you signed solidarily, as surety, or as guarantor	Ask for the loan documents, statement of account, payment history, and proof of default
You are a co-maker who already paid	You may recover the proper share from the principal borrower or other co-debtors	Send demand and file reimbursement claim if unpaid
You are the spouse of a co-maker	Your spouse’s personal debt does not automatically bind all conjugal or community property unless the law’s conditions are met	Check the property regime and whether the debt benefited the family

For married persons, the Family Code is important. Under Article 94, the absolute community may be liable for debts contracted during marriage by both spouses, by one spouse with the consent of the other, or by one spouse without consent to the extent the family benefited. Under Articles 121 and 122, similar rules apply to the conjugal partnership of gains. (Lawphil)

Legal Basis: Rights and Obligations When a Co-Maker Refuses to Pay

The creditor may collect from one solidary co-maker

If the co-maker is solidarily liable, the creditor does not have to first exhaust the assets of the principal borrower. The creditor may sue or demand payment from the co-maker directly under Article 1216 of the Civil Code. (Lawphil)

This often surprises co-makers who signed only “as a favor” for a friend, sibling, employee, kasambahay, OFW relative, or business partner. In court, the signed document usually matters more than the private arrangement between the borrower and the co-maker.

A co-maker who pays may demand reimbursement

If one solidary debtor pays the debt, Article 1217 of the Civil Code allows that person to claim from the co-debtors the share corresponding to each, with interest from the time of payment. If a co-debtor is insolvent, the unpaid share may be borne proportionately by the others. (Lawphil)

For guarantors, Article 2066 says the guarantor who pays for the debtor must be indemnified by the debtor. The indemnity includes the total amount of the debt, legal interest from the time payment was made known to the debtor, certain expenses after notice, and damages if due. Article 2067 also gives the paying guarantor subrogation, meaning the guarantor steps into the creditor’s rights against the debtor. (Lawphil)

Delay and damages may start after demand

Under Article 1169 of the Civil Code, persons obliged to deliver or do something generally incur delay from the time the creditor judicially or extrajudicially demands performance. Article 1170 makes a debtor liable for damages if the debtor is guilty of fraud, negligence, delay, or violates the terms of the obligation. (Lawphil)

This is why a clear written demand letter is not just a formality. It helps establish default, fixes the amount being claimed, and creates a paper trail.

Penalties and interest must still be reasonable

Loan contracts often include penalties, attorney’s fees, collection charges, and interest. Courts do not automatically approve excessive charges. Article 1229 allows the judge to reduce a penalty if the principal obligation was partly or irregularly complied with, or if the penalty is iniquitous or unconscionable. Article 2209 provides that if a money obligation is delayed and there is no stipulation, legal interest applies. (Lawphil)

Step-by-Step: What to Do If a Co-Maker Refuses to Pay

1. Get the complete loan file

Before sending threats or filing a case, gather the documents that prove the debt and the co-maker’s exact liability.

Look for:

Promissory note
Loan agreement
Co-maker’s undertaking
Disclosure statement, if from a lending or financing company
Amortization schedule
Statement of account
Receipts and proof of partial payments
Demand letters from the creditor
Chattel mortgage, real estate mortgage, or pledge documents, if any
IDs and addresses of the borrower and co-maker
Text messages, emails, chat screenshots, or written acknowledgments

Pay special attention to the signature page. Look for words like solidary, jointly and severally, surety, guarantor, co-maker, principal debtor, and continuing guaranty.

2. Compute the correct unpaid amount

Do not rely on a rough verbal balance. Prepare a written computation showing:

Original principal
Amount actually released
Payments made
Interest already paid
Remaining principal
Contractual interest, if valid
Penalties, if valid and reasonable
Attorney’s fees or collection fees, if stipulated
Foreclosure proceeds or collateral value applied to the debt, if any
Net amount still unpaid

If there was foreclosure of collateral, remember that the co-maker may still be liable for a deficiency if the obligation is a loan secured by collateral and the document creates solidary liability. In Bicol Savings & Loan Association v. Guinhawa, the Supreme Court recognized that a creditor could recover a deficiency after foreclosure from a solidary co-maker. (Lawphil)

3. Send a written demand letter

A demand letter should be specific, calm, and evidence-based. It should state:

Name of borrower and co-maker
Date and amount of the loan
Contract or promissory note being enforced
Amount due as of a specific date
Breakdown of principal, interest, penalties, and payments
Deadline to pay or propose settlement
Payment options
Warning that legal action may follow if unpaid

Send it in a way you can prove later: registered mail, courier with tracking, personal service with receiving copy, email with acknowledgment, or messaging app screenshots if that is the parties’ normal channel.

Article 1155 of the Civil Code also states that prescription is interrupted when an action is filed in court, when there is a written extrajudicial demand by the creditor, or when the debtor makes a written acknowledgment of the debt. (Lawphil)

4. Try a written settlement if payment is possible

If the co-maker admits liability but cannot pay immediately, put the settlement in writing.

A practical settlement agreement should include:

Total acknowledged balance
Payment schedule
Due dates
Mode of payment
Consequence of missed installments
Waiver or reduction of penalties, if agreed
Signatures of all parties
Valid IDs
Notarization, especially for larger amounts

If a party is abroad, a Special Power of Attorney or affidavit may need consular notarization or apostille, depending on where it is executed and where it will be used. DFA apostille guidance lists notarized instruments such as Special Powers of Attorney and affidavits among documents that may require proper authentication. (Apostille Philippines)

5. Check if barangay conciliation is required

Many collection disputes between individuals must first pass through barangay conciliation before a court case is filed, especially when the parties live in the same city or municipality. Supreme Court Circular No. 14-93 explains that prior recourse to the Katarungang Pambarangay process under the Local Government Code is generally a pre-condition before filing a complaint in court or government offices, subject to exceptions. (Lawphil)

In practice, this means you may need:

Complaint before the barangay
Summons to the borrower and co-maker
Mediation before the Punong Barangay
Conciliation before the Pangkat, if needed
Settlement agreement, or
Certificate to File Action if settlement fails

Barangay timelines vary, but many disputes move within a few weeks. Bottlenecks include wrong addresses, parties refusing to appear, parties living in different cities, or one party being abroad.

6. File a small claims case if the amount qualifies

For many unpaid co-maker loan disputes, small claims is the most practical court remedy.

The Supreme Court’s small claims materials refer to the Rules on Expedited Procedures in the First Level Courts under OCA Circular No. 69-2022, and the small claims coverage is for money claims not exceeding ₱1,000,000 exclusive of interest and costs. (Supreme Court of the Philippines)

Small claims are filed in first-level courts such as the Metropolitan Trial Court, Municipal Trial Court in Cities, Municipal Trial Court, or Municipal Circuit Trial Court. The Supreme Court has stated that small claims are intended to have one hearing day, with judgment rendered within 24 hours from termination, and that the decision is final, executory, and unappealable. (Supreme Court of the Philippines)

Small claims are useful because:

The forms are simplified.
Lawyers generally do not appear for the parties at the hearing.
The process is faster than an ordinary civil case.
It is designed for ordinary people and small businesses.
The decision can proceed to execution if the losing party does not pay.

As of the Judiciary’s electronic filing transition, civil cases in first- and second-level courts include small claims within the coverage of electronic filing and service rules; by December 1, 2024, civil cases before those courts were directed to use electronic transmittal as the primary manner of filing pleadings and other court submissions. (Office of the Court Administrator)

7. File an ordinary civil action if small claims does not fit

A regular collection case may be needed if:

The claim exceeds the small claims threshold.
The case involves complex issues like fraud, forgery, corporate liability, mortgage foreclosure, or multiple contracts.
You need provisional remedies.
There are complicated defenses or counterclaims.
The parties or evidence are spread across different places.

Regular civil cases take longer. Timelines depend heavily on the court’s docket, service of summons, mediation, pre-trial, availability of witnesses, and whether the defendant actively contests the claim.

Required Documents, Fees, and Timeline

Item	Why it matters
Promissory note or loan agreement	Proves the loan and the co-maker’s exact liability
Co-maker undertaking or surety/guaranty document	Shows whether liability is solidary, joint, suretyship, or guaranty
Statement of account	Shows the current balance and charges
Proof of loan release	Helps prove the borrower actually received or benefited from the loan
Receipts and payment history	Prevents double counting and excessive claims
Demand letter and proof of service	Helps prove default and interruption of prescription
Barangay Certificate to File Action	Needed when Katarungang Pambarangay applies
Valid IDs and addresses	Needed for service, identification, and court forms
SPA or representative authority	Needed if a party is abroad, unavailable, or represented
Apostille or consular notarization	Often needed for documents executed abroad
Court filing fees	Assessed by the Office of the Clerk of Court based on the claim and applicable fee rules

For prescription, written contracts generally have a ten-year period from the time the right of action accrues, while oral contracts generally have a six-year period. A written demand, court filing, or written acknowledgment of the debt can interrupt prescription under Article 1155. (Lawphil)

Common Mistakes When Dealing With a Refusing Co-Maker

Mistake 1: Assuming “I did not receive the money” is enough

A solidary co-maker may still be liable even if the proceeds went to the principal borrower. The question is not only who received the money, but what the co-maker agreed to in writing.

Mistake 2: Not reading the words “jointly and severally”

Many people sign loan documents quickly because the borrower is a relative, officemate, partner, or friend. Those three words can mean the co-maker may be asked to pay the entire debt.

Mistake 3: Paying without getting receipts and a release

If you are a co-maker paying the lender, get proof. Ask for:

Official receipt or acknowledgment receipt
Updated statement of account
Written release, if fully paid
Assignment or subrogation documents, if appropriate
Copies of cancelled checks or bank transfer confirmations

Without proof, it becomes harder to claim reimbursement from the borrower.

Mistake 4: Ignoring summons or barangay notices

A co-maker who ignores court papers may lose the chance to raise valid defenses, such as forgery, lack of solidary wording, payment, prescription, excessive penalties, or wrong computation.

Mistake 5: Using shame, threats, or online posting

A creditor may demand payment, but collection must still be lawful. Financing and lending companies are covered by SEC rules on unfair debt collection practices, including rules against abusive or improper collection conduct. (SEC Appointment System)

Mistake 6: Treating non-payment as automatically criminal

The 1987 Constitution states that no person shall be imprisoned for debt. Ordinary refusal or inability to pay a loan is generally a civil matter. Criminal liability may arise only if there are separate facts, such as deceit amounting to estafa under Article 315 of the Revised Penal Code, or issuance of a bouncing check under Batas Pambansa Blg. 22. (Lawphil)

Special Situations

The co-maker is an OFW or lives abroad

You can still pursue the claim, but service, representation, and document authentication become practical issues. If the co-maker is abroad, a Philippine representative may need a properly notarized or apostilled Special Power of Attorney. If the case requires personal appearance, the court will determine whether appearance through a representative is allowed for a valid cause. (Supreme Court of the Philippines)

The borrower disappeared

If the co-maker is solidarily liable, the creditor may still proceed against the co-maker even if the principal borrower cannot be located. In Inciong, the Supreme Court noted that the creditor’s inability to proceed against one debtor did not release the solidary co-maker; the co-maker’s remedy was against the other co-makers as provided by law. (Lawphil)

The loan had collateral

Collateral does not automatically erase co-maker liability. If foreclosure proceeds are insufficient, the unpaid deficiency may still be collectible depending on the contract and the type of transaction. This is especially important for vehicle loans, equipment loans, business loans, and loans secured by chattel mortgage. (Lawphil)

The co-maker says the signature was forged

Forgery is a serious defense, but it must be proven. A person raising forgery should preserve original documents, compare signatures, identify who witnessed signing, and consider handwriting examination if the case reaches court. Courts are usually cautious with forgery claims because signed loan documents carry evidentiary weight unless convincingly disproved.

The co-maker signed a blank document

Signing blank promissory notes or forms is dangerous. In Inciong, the Supreme Court emphasized the strength of written evidence and noted that fraud must be established by clear and convincing evidence, not merely by self-serving testimony. (Lawphil)

Frequently Asked Questions

Can a co-maker be forced to pay the whole loan in the Philippines?

Yes, if the co-maker signed as a solidary debtor, surety, or jointly and severally liable co-maker. Under Article 1216 of the Civil Code, the creditor may proceed against any one or all solidary debtors until the debt is fully collected. (Lawphil)

What if the co-maker did not receive any money from the loan?

That fact alone may not remove liability. If the co-maker signed a solidary undertaking, the creditor may still collect based on the written promise to pay. The co-maker’s remedy may be reimbursement from the borrower after payment.

Can a co-maker sue the borrower after paying the loan?

Yes. Article 1217 allows a solidary debtor who paid to claim from co-debtors the share corresponding to each. If the person was a guarantor who paid, Article 2066 allows indemnity from the debtor. (Lawphil)

Do I need to send a demand letter before filing a case?

A demand letter is usually very helpful and often practically necessary. It proves that payment was requested, fixes the amount claimed, may establish delay under Article 1169, and may interrupt prescription under Article 1155. (Lawphil)

Do we need barangay conciliation for a co-maker loan dispute?

Often yes, if the dispute is between individuals covered by the Katarungang Pambarangay rules, especially if they live in the same city or municipality and no exception applies. If settlement fails, the barangay issues a Certificate to File Action. (Lawphil)

Can I file a small claims case against a co-maker?

Yes, if the claim qualifies as a money claim within the small claims threshold and the evidence is straightforward. Current Supreme Court small claims materials refer to money claims not exceeding ₱1,000,000, exclusive of interest and costs. (Supreme Court of the Philippines)

Can the co-maker be jailed for refusing to pay?

Not for debt alone. The Constitution prohibits imprisonment for debt. Criminal liability requires separate criminal facts, such as fraud at the time of borrowing or issuance of a worthless check under BP 22. (Lawphil)

What if the co-maker is abroad?

The claim may still proceed, but practical problems include locating the co-maker, serving papers, securing authenticated documents, and arranging a representative through a properly executed SPA. Documents signed abroad may need consular notarization or apostille. (Apostille Philippines)

Does foreclosure of collateral release the co-maker?

Not always. For a loan secured by collateral, foreclosure may reduce the debt by the proceeds of sale, but a deficiency may still be collectible from a solidary co-maker if the contract and law allow it. (Lawphil)
