What must occur for a conditional contract to be enforceable?

For a conditional contract to be enforceable, the crucial factor is that the specific condition outlined in the contract must be met. Conditional contracts are agreements where the obligations of the parties depend on the fulfillment of a certain condition. This means that the contract will only become effective or binding if the condition occurs as stipulated.

When the condition is satisfied, parties are required to fulfill their obligations as defined in the contract. For instance, in an insurance context, if a certain event occurs (like a loss), the insurance company is obligated to pay out, provided the insured has met all other terms stipulated in the contract. Therefore, the enforceability of a conditional contract hinges primarily on the occurrence of the condition detailed within it.

While performance of all parties, payment, or written documentation may play roles in other types of contracts, they do not negate the fundamental requirement of having the condition met for a conditional contract's enforceability. In essence, the condition acts as the trigger that activates the duties of the parties involved in the contract.
