Which element ensures the contract is enforceable at law?

• A. Offer and acceptance
• B. Competent parties
• C. Insurable interest
• D. Legal purpose

Answer: (D)

A contract must have a lawful objective to be enforceable. If the contract aims at something illegal or against public policy, a court won’t enforce it, even if there was an offer and acceptance and both parties were capable. The other elements relate to how a contract is formed, but legality of the purpose is what makes enforcement possible. Insurable interest applies specifically to insurance contracts to prevent wagering, not to general enforceability.
