When one writes a letter to cancel a contract, include the specific terms of the contract under which termination of the agreement is allowed. A letter of cancellation must specify the effective date of the termination. The letter should be addressed to the appropriate contact person and address.
Before the letter is written, read through the contract, and confirm that the contract is able able to canceled. Language about the terms of cancellation is often found in a termination clause. Include the specific language, or reference to the specific section, in the letter of termination.
Many contracts specify to whom notices must be given, the acceptable forms of notice and mandatory time frames. Be sure to follow the requirements specified by the contract. Address the letter of contract termination to the person specified in the contract. If a minimum of time is required for notice, then be sure the termination date allows for this time.
A notice of contract termination creates a record that the other party has been notified about the cancellation and the end date. Document the mailing of the letter by sending it via certified mail. This way, the other party cannot claim not to have received the notice.
