What Is a Demand Letter for Contract Breach?
A demand letter for breach of contract is a formal written notice from the aggrieved party (or their lawyer) to the breaching party, demanding that they either: (1) fulfill their contractual obligations (specific performance), or (2) accept the rescission of the contract and pay damages. It formally places the breaching party in mora (delay/default) under Article 1169 of the Civil Code, which is the point from which damages and interest begin to accrue.
Civil Code Basis: Articles 1191 and 1169
Under Article 1191 of the Civil Code, the aggrieved party in a bilateral contract may choose between:
- Specific performance — demand fulfillment of the contractual obligation, with damages
- Rescission — treat the contract as cancelled and recover what was performed, with damages
Under Article 1169, the debtor is in default (mora) from the moment the creditor judicially or extrajudicially demands fulfillment of the obligation. A demand letter is the extrajudicial demand that triggers mora — meaning damages and interest begin to accrue from the date the letter is received.
