In the Philippines, a business generally cannot collect a penalty, late fee, surcharge, or extra charge that was not agreed upon in the contract. A seller, lender, landlord, supplier, or service provider cannot simply add a “penalty” later because payment was delayed, the customer cancelled, or the account became inconvenient to collect. Philippine law respects contracts, but it also requires fairness, consent, written stipulation for interest, and proper disclosure—especially in consumer and credit transactions.

There are important exceptions and nuances. A business may still recover the unpaid principal obligation, proven actual damages, legal interest in proper cases, or a court-awarded amount even if a specific penalty clause is missing. But that is different from unilaterally inventing a penalty fee after the fact.

The Short Answer: Usually No

A business cannot validly collect a penalty that is not:

stated in the signed contract;
clearly incorporated in the terms and conditions accepted by the customer;
disclosed before the transaction was completed;
authorized by law or regulation; or
awarded by a court, quasi-judicial agency, or lawful settlement.

This applies to common Philippine situations such as:

a landlord adding a “late payment penalty” not written in the lease;
a supplier adding 5% monthly penalty on an unpaid invoice even if the purchase order was silent;
a gym, school, clinic, or service provider adding cancellation charges not disclosed beforehand;
an online seller adding “storage fees” after the buyer delays pickup;
a lending company charging hidden penalties not disclosed in the loan documents;
a business printing penalty terms only on a later invoice after the deal was already agreed.

The reason is simple: under the Civil Code of the Philippines, obligations arising from contracts have the force of law between the parties and must be complied with in good faith. But the same rule also means that one party cannot change the contract alone. Articles 1159 and 1306 recognize binding contractual obligations and freedom to stipulate terms, but only within the limits of law, morals, good customs, public order, and public policy. (Lawphil)

What Counts as a “Penalty” in a Philippine Contract?

A penalty is an additional amount imposed because a party failed to comply with an obligation. In everyday business documents, it may be called:

penalty charge;
late payment fee;
surcharge;
default charge;
collection charge;
liquidated damages;
cancellation fee;
rebooking fee;
storage fee;
administrative fee;
attorney’s fees;
interest on overdue accounts.

The label is not controlling. If the purpose is to punish late payment, default, cancellation, or breach, Philippine courts may treat it as a penalty, liquidated damages, interest, or damages depending on its wording and function.

Under Article 1226 of the Civil Code, a penal clause is a contractual penalty that usually substitutes for damages and interest in case of non-compliance, unless the contract says otherwise. The same Civil Code provisions state that the penalty may be enforced only when it is demandable under the law, and Article 1229 allows courts to reduce penalties that are iniquitous or unconscionable. (Lawphil)

In practical terms: even if a penalty is written, it may still be reduced by a court if it is excessive. If it is not written or agreed at all, the business has a much weaker basis to collect it.

Legal Basis: Why a Business Cannot Just Add Penalties Later

Contracts bind both sides, but only as agreed

Article 1159 of the Civil Code says contractual obligations have the force of law between the parties and must be complied with in good faith. This protects businesses and customers alike. If the customer agreed to pay a specific penalty, the customer may be bound. But if the customer did not agree, the business cannot later impose a new burden and call it part of the deal. (Lawphil)

Article 1306 also allows parties to establish terms and conditions they consider convenient, but those terms cannot be contrary to law, morals, good customs, public order, or public policy. (Lawphil)

So the key question is not merely: “Does the business want to charge a penalty?”

The real question is: Did the customer agree to that penalty before or at the time the contract was perfected?

Interest must generally be expressly stipulated in writing

If the extra charge is interest, Article 1956 of the Civil Code is especially important: no interest is due unless it has been expressly stipulated in writing. (Lawphil)

This matters in unpaid invoices, loans, installment sales, and service contracts. A business cannot normally say, “Since you are late, we will charge 3% monthly interest,” if there was no written agreement for that interest.

The Supreme Court has repeatedly applied this principle. In Lara’s Gifts & Decors, Inc. v. Midtown Industrial Sales, Inc., the Court discussed that stipulated interest controls when validly agreed, but in the absence of stipulated interest, legal interest rules apply. The Court also emphasized that stipulated interest must not be excessive or unconscionable, and that compounding interest generally requires an express written stipulation or legal basis. (Supreme Court E-Library)

Courts may impose legal interest, but that is different from a business-made penalty

Article 2209 of the Civil Code provides that when an obligation consists of paying a sum of money and the debtor is in delay, damages may take the form of agreed interest, or legal interest if there is no stipulation. (Lawphil)

This does not mean a business may invent any penalty rate it wants. It means that in a proper case, especially after judicial or extrajudicial demand, legal interest may apply under Civil Code and Supreme Court rules.

In Nacar v. Gallery Frames, the Supreme Court clarified the use of the 6% per annum legal interest rate in monetary awards. Later cases, including Lara’s Gifts, continued to explain when stipulated interest applies and when legal interest applies. (Lawphil)

Even written penalties can be reduced if excessive

A penalty clause is not automatically enforceable in full just because it appears in a contract. Article 1229 of the Civil Code allows courts to reduce a penalty when there has been partial or irregular compliance, and even when there has been no performance if the penalty is iniquitous or unconscionable. (Lawphil)

In Ligutan v. Court of Appeals, the Supreme Court dealt with loan penalties and recognized that whether a penalty is reasonable or iniquitous depends on the circumstances, including the purpose of the penalty, the nature of the obligation, the mode of breach, the consequences, and the relationship of the parties. (Supreme Court E-Library)

When a Penalty May Be Collectible Even If It Is Not in the Main Signed Contract

A penalty does not always have to appear in one formal document titled “Contract.” Philippine contracts may be shown through several documents and acts. The issue is whether the penalty was clearly part of the agreement.

A business may have a stronger basis to collect if the penalty was stated in:

Source of penalty term	When it may be enforceable	Common issue
Signed contract	Usually enforceable if clear and not unconscionable	Excessive penalties may be reduced
Promissory note	Enforceable if signed and specific	Interest must be in writing
Lease agreement	Enforceable if late fee or penalty is clear	Landlords often add verbal penalties later
Purchase order accepted by supplier	May bind both sides if accepted before delivery	Conflicting invoice terms may cause disputes
Quotation or proposal accepted by customer	May form part of the agreement	Must be accepted, not merely sent
Website or app terms and conditions	Possible if user had notice and accepted before transaction	Hidden or changed terms may be challenged
Invoice terms	Stronger if issued before acceptance or consistently accepted in prior dealings	Weak if printed only after the transaction
Statement of account	Valid only if it reflects agreed charges	Not enough by itself to create new penalties

The practical test is: Was the customer informed of the penalty and did the customer accept it before being bound?

Examples of Penalties Businesses Commonly Try to Collect

Example 1: Unpaid invoice with no penalty clause

A supplier sells goods worth ₱80,000. The buyer delays payment. The invoice only states the price and due date. After 60 days, the supplier adds “5% monthly penalty.”

If the buyer never agreed to that 5% monthly penalty, the supplier may demand the unpaid ₱80,000. It may also make a written demand and later claim legal interest or damages in the proper forum. But the supplier cannot simply impose the 5% monthly penalty as if it were part of the contract.

Example 2: Lease contract silent on late penalties

A tenant pays rent late. The lease says rent is due every 5th day of the month, but it does not mention late fees. The landlord then demands ₱1,000 per day as penalty.

The landlord may demand unpaid rent and may pursue lawful remedies for breach of lease. But the daily penalty is vulnerable because it was not agreed upon.

Example 3: Contract says “subject to company policy”

A customer signs a service contract saying cancellations are “subject to company policy,” but the policy was never attached, shown, linked, or explained.

The business may have difficulty enforcing a cancellation penalty unless it can prove the customer had notice of the specific policy before agreeing. A vague reference to an unseen policy is weaker than a clear, signed schedule of fees.

Example 4: Online lending app with hidden fees

A borrower receives a small online loan. The app deducts processing fees and later charges penalties not clearly disclosed in the loan disclosure statement.

For covered loans by lending companies, financing companies, and their online lending platforms, disclosure and rate-cap rules may apply. BSP Circular No. 1133 covers certain unsecured, general-purpose loans not exceeding ₱10,000 with a tenor of up to four months, and prescribes ceilings on interest and other charges for covered loans. (Bangko Sentral ng Pilipinas)

Special Rules for Consumer Transactions

If the transaction is a consumer transaction, the business must also consider the Consumer Act of the Philippines, Republic Act No. 7394.

RA 7394 declares a policy of protecting consumers against deceptive, unfair, and unconscionable sales acts and practices, and of giving consumers adequate rights and means of redress. (Supreme Court E-Library)

This matters when a business:

hides penalty fees in fine print;
advertises “no hidden charges” but later adds charges;
discloses penalties only after payment;
makes cancellation terms difficult to find;
changes fees without clear notice;
uses confusing credit terms;
pressures consumers to pay charges they never agreed to.

For consumer credit, RA 7394 also recognizes the importance of full disclosure of the true cost of credit. (Supreme Court E-Library)

Special Rules for Loans, Financing, and Credit Cards

Lending companies and financing companies

Under RA 9474, or the Lending Company Regulation Act of 2007, lending companies may grant loans with reasonable interest rates and charges as agreed with the debtor, but the agreement must comply with the Truth in Lending Act and the Consumer Act. (Supreme Court E-Library)

The Truth in Lending Act, RA 3765, requires disclosure of finance charges in credit transactions to protect citizens from lack of awareness of the true cost of credit.

This is why loan documents usually include a disclosure statement showing:

principal amount;
finance charges;
deductions;
net proceeds;
effective interest rate;
penalty charges;
payment schedule;
consequences of default.

If a lending company did not disclose a penalty properly, the borrower may have grounds to dispute it with the company, the SEC, or the appropriate forum.

Credit cards

Credit card issuers are subject to special disclosure rules. RA 10870, the Philippine Credit Card Industry Regulation Law, requires credit card issuers to disclose computations and notify cardholders at least 90 days before changes in the manner of computation and fees. (Supreme Court E-Library)

The BSP Manual of Regulations for Banks also states that late payment fees or penalties for late payment shall not be collected from cardholders unless fully disclosed in the contract or agreement between the bank and cardholder. (Bangko Sentral ng Pilipinas)

So for credit cards, the rule is even clearer: late payment penalties must be disclosed in the card agreement.

What a Business Can Still Collect If No Penalty Was Agreed

Even if no penalty is stated, the debtor or customer does not get a free pass. The business may still be able to collect lawful amounts.

What the business wants to collect	Collectible if not stated in contract?	Explanation
Principal amount	Yes	The unpaid price, rent, loan, or service fee remains due if validly owed
Contractual penalty	Usually no	Must be agreed, usually in writing
Interest on loan	Generally no unless written	Article 1956 requires express written stipulation
Legal interest	Possibly	May apply in proper cases after demand or judgment
Actual damages	Possibly	Must be proven with evidence
Attorney’s fees	Not automatic	Usually requires stipulation or legal basis and court approval
Collection agency fee	Usually no against debtor unless agreed	Business may hire collector, but cannot always pass the cost to debtor
Court costs	Possibly	Court may award costs according to procedural rules
Moral or exemplary damages	Rare in ordinary collection disputes	Requires legal and factual basis, not mere non-payment

Step-by-Step: What to Do If a Business Is Demanding an Unstated Penalty

1. Ask for the legal and contractual basis

Do not argue only by phone. Ask for a written breakdown.

Request copies of:

signed contract;
promissory note;
terms and conditions;
quotation or proposal;
purchase order;
invoice;
statement of account;
disclosure statement, if a loan;
schedule of fees;
written notice of fee changes;
computation of penalties.

Use simple wording:

Please provide the specific contract provision, disclosure statement, or legal basis for the penalty charge, including the date when I agreed to it and the computation used.

2. Separate the principal from the disputed penalty

A common mistake is refusing to pay everything because the penalty is wrong. If the principal amount is truly owed, separate it from the disputed charge.

For example:

principal: ₱50,000;
agreed interest: none;
disputed penalty: ₱12,500;
your position: willing to discuss principal, disputing penalty.

This shows good faith and may reduce the risk of escalation.

3. Check whether the penalty was actually incorporated

Look for language such as:

“late payments shall incur 3% interest per month”;
“subject to attached Schedule of Fees”;
“customer agrees to the Terms and Conditions at [link]”;
“penalty of ₱500 per day of delay”;
“liquidated damages equivalent to 20% of contract price.”

Then ask:

Was this term shown before I accepted?
Did I sign it?
Was it in the version existing at the time?
Was the link accessible?
Was the policy attached?
Did I continue the transaction after receiving clear notice?

If the penalty appeared only after the transaction—such as on a later invoice or collection letter—it is easier to dispute.

4. Send a written dispute or reply

Your reply should be calm and specific. Avoid threats. State that you dispute the penalty because it was not agreed or disclosed.

Include:

account or invoice number;
transaction date;
amount you admit, if any;
amount you dispute;
request for documents;
proposed resolution.

Keep proof of sending: email, courier receipt, screenshots, or registered mail receipt.

5. File with the proper forum if needed

The correct forum depends on the transaction.

Type of dispute	Possible first forum	Notes
Consumer purchase or service	DTI Consumer CARe / DTI-FTEB	Useful for unfair or undisclosed charges in consumer transactions
Credit card issue	Bank’s dispute channel, then BSP consumer assistance	Keep statements and card agreement
Lending or financing company	SEC, especially for lending/financing company practices	Check if the company is SEC-registered
Dispute between individuals in same city/municipality	Barangay conciliation may be required	Especially before court filing
Money claim up to ₱1,000,000	Small claims court	For payment or reimbursement of money
Larger or complex contract dispute	Regular court action	May require full litigation

DTI’s Fair Trade Enforcement Bureau handles consumer complaints and adjudication involving violations of RA 7394 and other fair trade laws. DTI also provides an online complaint channel through the Consumer CARe system. (Fair Trade Enforcement Bureau)

For court claims, the Supreme Court’s Rules on Expedited Procedures increased the small claims threshold to ₱1,000,000 and covers money owed under leases, loans, credit accommodations, services, and sale of personal property. The rule also provides for a simplified process, one hearing day, and judgment within 24 hours from termination of the hearing. (Supreme Court of the Philippines)

Barangay Conciliation: When It Matters

For many local disputes, especially between individuals actually residing in the same city or municipality, barangay conciliation under the Katarungang Pambarangay system may be a pre-condition before filing in court. Supreme Court Circular No. 14-93 explains that disputes subject to barangay conciliation must first go through that process before a complaint is filed in court or government offices, subject to exceptions. (Lawphil)

In a penalty dispute, barangay conciliation may arise when:

a landlord and tenant live in the same city;
a small business owner and customer are local residents;
a personal loan or informal business transaction is involved;
the claim is not excluded by law.

If settlement is reached at the barangay, the Local Government Code allows enforcement of the amicable settlement or arbitration award by the lupon within six months; after that, it may be enforced by action in the proper city or municipal court. (Lawphil)

Practical Documents to Prepare

Whether you are the customer disputing the penalty or the business trying to collect, documents matter more than anger, screenshots without context, or verbal claims.

Document	Why it matters
Signed contract	Shows agreed terms
Promissory note	Important for loans and payment obligations
Terms and conditions	Shows additional incorporated terms
Proof of acceptance	Shows the customer agreed before being bound
Invoice and statement of account	Shows amount billed and due date
Official receipts	Shows partial or full payment
Bank transfer records	Proves payments made
Emails, SMS, Viber, Messenger, WhatsApp messages	May show agreement, demands, admissions, or objections
Demand letter	Helps establish default and timeline
Disclosure statement	Important in loans and credit transactions
Screenshots of app terms	Useful in online lending or e-commerce disputes
DTI, SEC, BSP, or barangay filings	Shows steps already taken

For screenshots, save the full conversation if possible, not just selected messages. Courts and agencies often look for context.

Common Pitfalls That Hurt Customers

Paying the penalty without protest

If you pay a disputed penalty without any written objection, the business may later argue that you accepted the charge. If you need to pay to avoid service interruption, write that payment is made “under protest” and specify the disputed amount.

Ignoring demand letters

Ignoring a demand letter can make the situation worse. A short written reply disputing the penalty and asking for the contractual basis is usually better than silence.

Admitting everything in chat

Avoid messages like “I know I owe everything” if you dispute the penalty. Be precise: “I acknowledge the principal balance of ₱, but I dispute the penalty of ₱ because I have not seen any agreed basis for it.”

Focusing only on fairness, not documents

Agencies and courts need evidence. “This is unfair” is not as strong as “The signed contract dated ___ contains no penalty clause, and the penalty first appeared in the statement of account dated ___.”

Common Pitfalls That Hurt Businesses

Adding penalties only in the invoice

Many businesses assume that printing “3% monthly penalty on overdue accounts” on an invoice automatically binds the customer. That is risky if the invoice was issued after the contract was already formed and the customer did not accept that term.

Using vague terms like “subject to charges”

A vague phrase may not be enough. If the business wants to collect penalties, it should state:

the triggering event;
the rate or amount;
when it starts;
whether it compounds;
whether it is based on principal only or outstanding balance;
whether VAT or other charges apply;
whether it is in addition to damages or in substitution for damages.

Charging both penalty and damages without clear basis

Article 1226 generally treats the penalty as a substitute for damages and interest unless there is a stipulation to the contrary. (Lawphil)

So if a business wants to claim penalty plus actual damages, the contract should say so clearly, and the damages must still be legally supportable.

Setting excessive penalty rates

Even a written penalty may be reduced. Courts may look at the nature of the obligation, amount involved, delay, partial payments, bargaining power, and whether the penalty is oppressive.

What If the Contract Allows the Business to Change Fees?

Some contracts say the business may change fees or terms. This is common in subscriptions, apps, credit cards, and service platforms.

That does not automatically mean any new penalty is valid. The business should still show:

the contract allowed changes;
the change process was followed;
the customer received notice;
the new charge applies prospectively, not retroactively;
the customer had a meaningful chance to cancel or reject when required by law or contract;
special laws, such as credit card or consumer protection rules, were followed.

For credit cards, RA 10870 requires advance notice of certain changes in computation and fees, and the cardholder may terminate the account if the change is unacceptable, subject to the law’s terms. (Supreme Court E-Library)

What If the Business Says “It Is Company Policy”?

“Company policy” is not automatically binding on a customer.

A company policy may become part of the contract if:

it was shown before the customer agreed;
it was attached or linked clearly;
the customer signed or clicked acceptance;
it was not hidden or misleading;
it does not violate law or public policy.

A policy that is internal, unpublished, changed after the transaction, or disclosed only after a dispute is much weaker.

What If the Customer Is a Foreigner or Overseas Filipino?

The basic contract rules are the same if Philippine law governs the transaction or if the dispute is filed in the Philippines. But practical proof issues may arise.

If documents are signed abroad

A Special Power of Attorney, affidavit, settlement authority, or other document executed abroad may need notarization in the country where it is signed and, depending on the country, an apostille or consular authentication before it is used in the Philippines.

This commonly happens when:

an OFW authorizes a relative to appear at barangay or court;
a foreign buyer disputes a Philippine real estate-related charge;
a foreign business sends an authorized representative;
a foreigner needs to submit an affidavit in a Philippine case.

If the business is foreign but operating in the Philippines

A foreign company selling to Philippine consumers may still face Philippine consumer, tax, registration, and jurisdiction issues depending on how it does business. If it uses Philippine-based entities, agents, payment channels, or platforms, the paper trail becomes important.

If the contract has a foreign law or arbitration clause

Some contracts specify foreign law, arbitration, or foreign venue. That clause must be reviewed carefully. Philippine mandatory laws may still matter in consumer, employment, land, lending, banking, or public policy issues.

How to Write a Simple Dispute Letter

A dispute letter does not need to sound aggressive. The goal is to create a clear record.

Use this structure:

Identify the account, invoice, contract, or transaction.
State the amount being charged as penalty.
Say that you dispute the penalty.
Ask for the contractual and legal basis.
State whether you admit the principal amount.
Request correction of the statement of account.
Keep a copy.

Sample wording:

I am writing regarding your demand for payment of ₱, including a penalty charge of ₱. I respectfully dispute the penalty charge because I have not been provided any signed contract, accepted terms and conditions, disclosure statement, or written agreement showing that I agreed to this penalty before or at the time of the transaction.

Please provide the specific contractual provision and computation supporting the penalty. Pending your clarification, I reserve all rights and objections regarding the disputed charge.

Frequently Asked Questions

Can a business charge late payment penalties if the contract is silent?

Usually, no. If the contract does not state a late payment penalty and the customer did not otherwise agree to it, the business cannot simply impose one later. The business may still demand the unpaid principal and may pursue legal interest or damages in the proper case.

Can a business charge interest on overdue invoices in the Philippines?

Only if there is a written stipulation for interest, or if legal interest applies under the Civil Code and Supreme Court rules after default, demand, or judgment. Article 1956 of the Civil Code states that no interest is due unless expressly stipulated in writing. (Lawphil)

What if the invoice says there is a penalty but the signed contract does not?

It depends on timing and acceptance. If the invoice term was disclosed before or at the time of contracting and accepted by the customer, it may form part of the agreement. If the penalty appeared only after the transaction was already completed, it is easier to dispute.

Are cancellation fees legal in the Philippines?

They can be legal if clearly disclosed and agreed before the customer became bound, and if the amount is not unfair, deceptive, unconscionable, or contrary to law. A cancellation fee imposed only after cancellation, without prior disclosure, is vulnerable.

Can a business send a collection agency for penalties I dispute?

A business may hire a collection agency, but the agency cannot lawfully collect amounts without basis or use abusive, deceptive, threatening, or harassing methods. You can ask for proof of authority, a breakdown of the debt, and the contractual basis of the penalty.

Can I file a DTI complaint for hidden penalties?

If it is a consumer transaction involving goods or services, a DTI complaint may be appropriate, especially if the charge appears deceptive, unfair, or unconscionable. DTI-FTEB handles consumer complaints under RA 7394 and related fair trade laws. (Fair Trade Enforcement Bureau)

Can I refuse to pay everything because the penalty is invalid?

Be careful. If you truly owe the principal amount, refusing to pay anything may expose you to a collection case. A safer approach is to dispute the penalty in writing while separating the principal amount from the disputed charges.

Can a court reduce a penalty even if I signed the contract?

Yes. Article 1229 of the Civil Code allows courts to reduce penalties when there has been partial or irregular compliance, or when the penalty is iniquitous or unconscionable. (Lawphil)

Can a business collect attorney’s fees if the contract does not mention them?

Attorney’s fees are not automatic. They may be awarded when there is a contractual stipulation or a legal basis, but courts still consider reasonableness. A collection letter saying “you must pay attorney’s fees” does not by itself prove that the debtor is legally bound to pay them.

Can an online lending app charge penalties not shown before I accepted the loan?

That is highly questionable. Lending and financing companies are subject to disclosure rules, and covered small-value, short-term loans may also be subject to BSP and SEC ceilings on interest, fees, and penalties. Keep screenshots, disclosure statements, loan agreements, and payment records.
