How to terminate a contract
Use a termination clause.
Many types of long-term and automatically renewing contracts have a termination clause. This gives you the steps you need to take if you want to terminate the contract.
A common termination clause says that the person who wants out of the contract must notify the others involved of his intent to do so. This must be in writing and within a certain number of days from when they want to end the contract or when it will be automatically renewed.
