How to adapt this contract termination

Before you write

Find the signed agreement, amendments and exact notice clause before writing.
Calculate the proposed end date and identify the notice address, delivery method and remaining obligations.

A practical example

For a support contract, refer to the agreement date and termination clause, state the final service date, and request an access handover and final invoice. Keep reasons separate from instructions about the handover.

Common mistake to avoid

Do not assume an email to your usual contact satisfies a clause requiring notice to a registered address. Do not backdate the notice.

Before you send

Check renewal windows, cure periods, fees and proof of delivery. Obtain advice if the right to terminate is disputed.

Fictional sample details are starting points to replace. Letter Studio formats documents; a logo, signature or stamp does not verify their contents or confer authority.
