Legal Requirements for Demand Letters in the Philippines
Disclaimer: This article is intended for general informational purposes only and does not constitute legal advice. For specific concerns, please consult a qualified attorney.

1. Introduction

A demand letter is a formal written communication typically sent by an aggrieved party (often through counsel) to another individual or entity, notifying the latter of a perceived legal obligation and requesting that certain actions be taken to remedy or address that obligation. In the Philippine legal context, demand letters play a significant role in civil cases, commercial disputes, and even criminal proceedings involving collection of sums of money. Understanding how demand letters function and what legal requirements they must follow is essential both for those sending the letter (creditors, aggrieved parties, and their counsel) and those receiving it.

2. Purpose and Importance of Demand Letters

Establishing a Formal Record: A demand letter helps create a documented trail showing that the aggrieved party attempted to resolve the matter before resorting to litigation. This is a common requirement in certain civil cases and is often used in evidence if the dispute progresses to court.
Triggering Obligations or Deadlines: Many Philippine laws or rules require that a formal demand be made before liability accrues, interest begins to run, or certain statutory time limits start or stop running. For example, under the Civil Code of the Philippines, interest on an obligation may begin to accrue only from the time of judicial or extrajudicial demand.
Facilitating Settlement: By outlining the claims and demands, a demand letter offers an opportunity for the parties to settle the dispute amicably, thereby avoiding litigation.
Serving as a Legal Notice: A well-drafted demand letter can serve as valid notice and can be used to support an allegation that the opposing party was informed about the legal consequences of failing to heed the demand.

3. Legal Basis and Framework

Demand letters in the Philippines draw their authority and relevance from various provisions of Philippine law and jurisprudence:

The Civil Code of the Philippines (Republic Act No. 386)
- Articles 1169 and 2209 of the Civil Code discuss the concept of “default” of the obligor. Typically, default begins when the debtor fails to perform an obligation after a demand has been made by the creditor. In many instances, interest or damages may only be charged from the date of demand.
- Article 1252 mentions how application of payments works, sometimes relating to amounts demanded in writing.
- Article 1953 and related provisions (on loans, obligations, and interest) clarify that the duty to pay interest and damages often starts from formal demand if the obligation does not specify otherwise.
The Rules of Court
- While the Rules of Court (particularly the Rules on Civil Procedure) do not strictly prescribe the required content of a demand letter, they do recognize the role of demand letters (e.g., Rule 70 on unlawful detainer actions typically requires a prior demand to vacate).
Relevant Jurisprudence
- Philippine Supreme Court decisions have repeatedly affirmed that a written extrajudicial demand is often required to place a debtor or lessee in default, or to show the good-faith efforts of the creditor or lessor to seek an amicable resolution.

4. Essential Components and Formalities

There is no single, universal statutory checklist for a demand letter’s content in the Philippines. However, to ensure effectiveness and legal adequacy, the following components are typically included:

Heading and Date
- Although not legally mandated, a clear heading helps identify it as a “Demand Letter,” along with the date of issuance. The date helps mark the starting point for interest accumulation or deadlines set out in the letter.
Name and Address of Recipient
- The letter should clearly state the name and address of the person or entity to whom the demand is directed. This ensures that the communication is properly addressed.
Statement of Facts
- A concise narration of the relevant facts: the existence of the obligation, background of the transaction or relationship, the date and manner of breach or non-performance, etc.
- Clarity in presenting the facts is crucial because the factual recitation supports the conclusion that the addressee has a legal responsibility.
Legal Basis or Grounds
- Although a demand letter need not be as exhaustive as a formal legal pleading, it often includes references to the relevant law or contractual provisions that establish the obligation.
- Examples include citing a specific clause in a contract or referencing a particular article in the Civil Code.
Demand or Relief Sought
- This is the core requirement: a clear and unequivocal statement of what the sender wants the recipient to do (e.g., pay a sum of money, cease an activity, comply with a contractual obligation, or vacate premises).
- In most collection or payment-related scenarios, the specific amount claimed should be stated.
Deadline or Timeframe
- Philippine jurisprudence recognizes that a debtor cannot be in default unless there is a clear demand and a time given to comply. Thus, the demand letter should impose a reasonable period within which the recipient must act (e.g., within fifteen (15) days from receipt).
Consequences of Non-Compliance
- The letter should outline the next steps or potential legal actions if the recipient fails or refuses to comply. This may include the filing of a lawsuit, an administrative action, or other remedies.
Signature and Authentication
- While a demand letter can be sent by the aggrieved party personally, it is often more effective if it comes from the party’s legal counsel. Having it notarized is not strictly required but can sometimes lend more formality and authenticity.

5. Service and Proof of Service

For a demand letter to be effective, it must be served in such a way that the sender can prove that the recipient actually received it. Common methods of service in the Philippines include:

Personal Delivery
- By physically delivering the demand letter to the recipient and asking them to acknowledge receipt.
- Alternatively, a courier service with an official delivery record or signature can also be used.
Registered Mail
- Sending via registered mail through the Philippine Postal Corporation, with a return card that serves as proof of mailing and proof of receipt once the recipient or an authorized agent signs the return card.
Courier or Private Delivery Services
- Many private couriers offer a tracking feature and can provide documentation that the letter was delivered to a specific address.

Retention of proof of service is essential if the matter proceeds to litigation. Courts commonly require evidence of proper service of the demand letter.

6. Legal Effects of a Demand Letter

Default and Accrual of Damages or Interest
- Under the Civil Code, a debtor is considered in default once a valid demand has been received and not complied with. From that point, legal interest and other damages may begin to accrue.
- The date of the demand letter (or proof of receipt) is often used by courts to determine the period for computing interest or damages.
Grounds for Legal Action
- If a debtor fails to heed the demand, the creditor has a stronger basis to file a civil action. The demand letter and any proof of service become part of the documentary evidence to show that extrajudicial measures were taken first.
Potential for Settlement
- The demand letter often prompts negotiation. Many legal disputes in the Philippines resolve at this early stage, avoiding the costs and delays of litigation.
Tolled or Interruption of Prescriptive Period
- In some cases, sending a demand letter can interrupt or toll the running of the statute of limitations (the prescriptive period for filing a case). As jurisprudence evolves, courts carefully examine if the content and manner of sending truly constitute a valid interruption.

7. Special Situations and Considerations

Demand Letters in Criminal Contexts
- Some criminal cases, particularly those involving Bouncing Checks (under Batas Pambansa Blg. 22), require the complainant to prove that a demand for payment was made to the drawer of the check and the drawer refused or failed to settle within a specific period.
- For BP 22 cases, failure to send a written demand within the proscribed period can jeopardize the prosecution’s case.
Demand to Vacate (Ejectment Cases)
- In unlawful detainer or ejectment suits, a demand to vacate the property is specifically required by law. The complaint may be dismissed if the complainant fails to show that a formal demand was served on the occupant or lessee.
Extra-Contractual or Tort Situations
- Demand letters can also be relevant in tort claims (e.g., indemnification for damages to property). While the letter itself is not always required by law, it can serve to mitigate litigation costs and show good-faith negotiation efforts.
Use of Multiple or Follow-Up Demand Letters
- If a recipient ignores or fails to respond, it is not uncommon for the sender to issue follow-up demands or final notices. While not mandatory, multiple notices can strengthen the sender’s argument that they exhausted all reasonable avenues for settlement.

8. Practical Tips for Drafting Demand Letters

Maintain Clarity and Brevity: Although the facts and legal basis must be clear, overly lengthy letters can bury the main points.
Avoid Inflammatory Language: Be firm but professional. Courts sometimes frown upon threatening or harassing language in demand letters.
Choose an Appropriate Tone: Striking a balance between firmness and openness to settlement is often the most effective approach.
Check for Factual Accuracy: An erroneous or exaggerated demand can weaken credibility if the matter goes to trial.
Consult a Lawyer When in Doubt: Particularly for significant claims, involving legal counsel at the outset can prevent mistakes in drafting, ensure the letter is consistent with procedural requirements, and preserve your rights effectively.

9. Consequences of Ignoring a Demand Letter

If a party receives a well-founded demand letter and opts to ignore it:

Risk of Default and Possible Litigation: Courts often treat a failure to respond or comply as an indicator of the debtor’s unwillingness to settle. This can expedite the creditor’s pursuit of judicial remedies.
Accumulation of Interest or Penalties: Depending on the nature of the obligation, ignoring a demand may lead to the accrual of interest or additional damages.
Adverse Inferences: In some cases, the court might infer that silence or inaction suggests that the recipient has little defense.

10. Conclusion

Demand letters occupy a unique and crucial position in Philippine legal practice. Although not every legal dispute formally requires a demand letter, it is a widespread and often beneficial tool for clarifying positions, encouraging settlement, and fulfilling procedural requirements. For individuals and organizations facing or initiating a claim, ensuring that the demand letter meets accepted legal standards—particularly with respect to factual clarity, service, timeframe, and consequences—is essential. Properly handling demand letters can save time, mitigate risks, and potentially resolve disputes without the need for protracted litigation.
