What characteristic of a contract states that both insured and insurer must meet specific conditions for the contract to be enforceable?

The characteristic of a contract that requires both the insured and the insurer to meet specific conditions for the contract to be enforceable is known as conditional. In an insurance contract, conditions are provisions that outline the actions and obligations that both parties must adhere to in order for the policy to remain valid. For example, the insured may need to pay premiums on time, while the insurer must provide coverage for specified events. If either party fails to meet these conditions, the contract may be considered void, and the promised benefits may not be provided.

In contrast, other options represent different aspects of contract characteristics. For instance, unilateral contracts involve one party making a promise or commitment while the other party does not have to fulfill a corresponding obligation; this is often seen in insurance where the insurer promises to pay a claim upon the insured's compliance without a two-way promise. Voidable contracts imply that one party has the option to void the contract under certain circumstances, often due to misrepresentation or other factors, but this does not necessarily relate to the condition of enforceability as described. Bilateral contracts involve mutual promises between two parties but do not emphasize the conditional nature inherent in insurance agreements, where specific actions determine enforceability.
