Breach of Contract Notice: Certified Mail letter template
Pre-filled template, USPS tracking and Electronic Return Receipt
When the other side stops performing, do not just stop paying or walk away: send a notice of breach with a demand to cure. Many contracts require written notice and a cure period before termination, and courts look for it even when the contract is silent. Skipping this step can turn the breaching party's lawyer loose on you instead.
The notice should cite the contract, describe each breach precisely, quantify the harm, and set a cure deadline. Sending it via USPS Certified Mail with Electronic Return Receipt creates dated proof that the notice was given and received, which controls when cure periods start and preserves your right to terminate or claim damages.
This template walks through each element and reserves your rights and remedies in writing.
