Which statement best defines the term 'aleatory' in contract law?

• A. The contract is cancellable at will
• B. Both parties may not receive equal value in a contract
• C. The contract is symmetrical
• D. Both parties receive equal value always

Answer: (B)

Aleatory contracts are defined by a performance that depends on an uncertain event, so the actual value exchanged between parties can be unequal. In insurance, the insured pays a premium, and the insurer’s obligation to pay only arises if a specified event occurs (like a death or loss). If the event doesn’t happen, the insurer keeps the premium, and if it does occur, the insurer pays a large benefit. This potential for unequal value, depending on whether the event happens, is what makes the statement that both parties may not receive equal value the best description of an aleatory contract.

The other ideas don’t fit as well: a contract being cancellable at will isn’t what aleatory describes, and neither symmetry nor always-equal value captures the uncertain, uneven exchange that characterizes aleatory arrangements, especially in insurance.
