What characterizes an aleatory contract?

An aleatory contract is characterized by the outcome being reliant on uncertain events. This means that the performance by one or both parties is contingent upon the occurrence of a specific event, which may or may not happen. In contexts like insurance, for example, the insurer's obligation to pay out a claim is dependent on an event occurring, such as an accident or a loss, which adds an element of unpredictability to the contract.

This nature of aleatory contracts means that the benefits received by each party can differ greatly, depending on the occurrence of the uncertain event. While one party may benefit significantly from the contract if the event occurs, the other may not receive an equivalent benefit, illustrating the inherent imbalance in value exchange compared to more traditional agreements where both parties are expected to receive equal value upon fulfillment. The other options fail to capture this key characteristic, as they suggest equal value exchange, ease of amendment, or equal contribution, which do not apply to the fundamental nature of aleatory contracts.
