Answer Details
A contract in which all parties have fully met their obligations is said to be terminated by performance.
Here's an explanation:
When a contract is terminated by performance, it means that all the parties involved have successfully carried out the duties and promises as outlined in the contract. Each party has done what they agreed to do, and once this has been completed, the contract comes to an end naturally.
For instance, if a person hires a painter to paint their house and the painter completes the job to the agreed specifications, then the contract is terminated by performance. Both parties have fulfilled their end of the agreement: the homeowner has paid, and the painter has completed the work.
