Which term describes an agreement that has no legal force or effect?

The term that describes an agreement that has no legal force or effect is "void." A void agreement is considered null from the moment it is created, meaning it cannot be enforced by either party in a court of law. This could be due to a variety of factors, such as the agreement involving illegal activities, the parties lacking the capacity to contract, or a failure to meet essential legal requirements. In essence, a void agreement is treated as if it never existed, which distinguishes it from other types of agreements that may be voidable or valid under certain circumstances.

In contrast, other options like "VOD," which is not a recognized legal term in this context, "waiver," which refers to the voluntary relinquishment of a known right, and "valid," which denotes an agreement that is legally enforceable and recognized by the law, do not accurately capture the concept of an agreement lacking any legal effect.
