List 4 general methods that a contract can be voluntarily or involuntarily terminated before completion.?

Answer 1

1. completion of both parties
2. agreement of both parties to terminate
3. death of either party (in some contracts)
4. destruction or termination of main item in the contract

Answer 2

It depends on the State the contract is written in. For instance, there is no such thing as a non-cancelable contract in California...You need to check the termination clauses within the specific contract.
