Before a lawsuit is filed, before a criminal complaint is drafted, before any formal legal proceeding begins — there is often a demand letter. It is the first formal assertion of your legal rights and the first formal notice to the other party that you intend to enforce them. Done correctly, a demand letter can resolve disputes faster and more cheaply than any court proceeding. Done poorly — or skipped entirely when it is required — it can fatally undermine your case.
What Is a Demand Letter?
A demand letter is a formal written notice from one party to another asserting a legal claim, stating the basis for that claim, specifying what action is demanded, and setting a deadline for compliance. It is not a pleading — it is a pre-litigation instrument. It may be drafted by a lawyer on behalf of a client or, in some cases, by the aggrieved party personally. Its legal weight derives from its content, its timing, and the manner in which it is served.
When Is a Demand Letter Legally Required?
Certain causes of action require prior demand as a substantive element of the offense or claim. In estafa by misappropriation under Article 315(1)(b) of the Revised Penal Code, a formal demand to return the entrusted property is required to establish the element of misappropriation and the accused's refusal to return — without a prior demand, the complaint is vulnerable to dismissal. In unlawful detainer cases under Rule 70 of the Rules of Court, a prior demand to vacate is a jurisdictional requirement — the MTC has no jurisdiction over an ejectment case unless the demand has been made and the defendant has failed to comply within the period allowed. In cases for recovery of sum of money, while demand is not always a strict jurisdictional prerequisite, it is necessary to put the debtor in default and to start the running of legal interest under Article 1169 of the Civil Code.
For BP 22 cases, the written notice of dishonor served on the drawer functions as a demand — and its receipt by the drawer is a critical element that triggers the five-banking-day period and establishes the presumption of knowledge of insufficient funds.
What a Proper Demand Letter Must Contain
A legally effective demand letter should clearly identify the parties — the sender and the recipient — and establish the relationship or transaction that gives rise to the claim. It should state the specific facts giving rise to the obligation: the contract, the loan, the trust arrangement, the bounced check, or whatever the legal basis for the claim may be. It should specify precisely what is being demanded — payment of a specific amount, vacating of a premises, return of specific property, cessation of specific conduct — and set a clear, reasonable deadline for compliance. It should state the legal and factual consequences of non-compliance: that a civil case will be filed, that a criminal complaint will be pursued, or both.
The letter should be factually accurate and legally grounded. Exaggerated or baseless threats in a demand letter — for instance, threatening criminal prosecution for a purely civil obligation with no criminal element — can expose the sender to liability for grave threats or unjust vexation if the threatened act is not actually legally supportable.
How to Serve a Demand Letter Properly
Proper service is not a formality — it is often decisive. The gold standard is service by registered mail with return card. The registry receipt and the signed return card together constitute proof that the letter was sent and received, including the date of actual receipt. Personal service with a signed acknowledgment is equally effective. Service by private courier with tracking confirmation is increasingly accepted in practice.
Sending a demand by ordinary email or chat message, while common in practice, carries evidentiary risk — it may be difficult to prove receipt, and courts have not uniformly accepted email printouts as proof of service without authentication. Where demand is a legal prerequisite — as in unlawful detainer or estafa — registered mail with return card is always preferable.
The Legal Effect of a Demand Letter
Beyond its role as evidence, a demand letter has several concrete legal effects. It puts the obligor in default, from which point legal interest begins to run on money obligations under Article 1209 of the Civil Code — currently six percent per annum under Bangko Sentral ng Pilipinas Circular No. 799. It tolls or interrupts prescription in some circumstances, depending on the applicable prescriptive period and how the demand is characterized. It demonstrates good faith on the part of the creditor, which courts consider favorably in awarding damages. And in many cases, it resolves the dispute entirely — a well-drafted demand letter from a lawyer, making clear the legal exposure of the other party, often produces payment or settlement without any need for further proceedings.
When the Other Party Ignores the Demand
Non-response or outright refusal to comply with a demand letter is not the end — it is the beginning of the next step. The appropriate next step depends on the nature of the claim: small claims proceedings for money claims not exceeding PHP 2,000,000; unlawful detainer before the MTC for ejectment matters; a civil complaint before the RTC for larger money claims or property disputes; a criminal complaint before the Prosecutor's Office for estafa, BP 22, or other criminal liability arising from the same facts. The demand letter and proof of service become exhibits in all of these subsequent proceedings.
