Which contract type requires conditions to be met by both parties to enforce it?

The correct choice indicates a conditional contract, which is defined by the necessity for specific conditions to be fulfilled by both parties for the contract to become enforceable. In the context of a conditional contract, an obligation exists that is contingent upon the occurrence of certain events or actions. This mutuality of conditions establishes the framework of the agreement, ensuring that both parties have responsibilities that must be met for the contract to proceed.

For example, in a conditional contract for the sale of a home, the buyer might need to obtain financing, while the seller may need to complete specific repairs. Both conditions must be satisfied for the transaction to be successfully executed, illustrating the symbiotic relationship established within such contracts.

Other types of contracts differ significantly in their requirements. An aleatory contract involves an outcome that depends on an uncertain event, making the obligations uneven. Personal contracts typically reflect individual agreements and may not require reciprocity in conditions for enforcement. A unilateral contract, on the other hand, involves one party making a promise in exchange for the act of another party, with only one side having enforceable obligations until that action is taken. Understanding these distinctions helps clarify why the correct choice focuses on mutual conditions necessary for enforcement in this context.
