Which term describes a contract that depends on uncertain future events?

The term that describes a contract depending on uncertain future events is "Aleatory." In the context of insurance contracts, an aleatory contract is one where the occurrence of an event, such as a loss or damage, triggers the obligations of the parties involved. The key characteristic of an aleatory contract is that the outcomes significantly rely on the occurrence of specific events that cannot be predicted with certainty at the time the contract is formed.

For example, in a typical insurance policy, the insurer agrees to pay a benefit upon the occurrence of a covered event (like an accident or natural disaster), which is uncertain and may not happen at all. This aspect creates an imbalance in the exchange of value—one party may receive a large benefit while the other may receive little to no benefit, depending on whether the uncertain event occurs.

In contrast, contracts that are considered adhesive often involve unequal bargaining power, where one party has significantly more power in determining the terms than the other. Unilateral contracts refer to agreements where only one party makes a promise or is obligated to fulfill their side of the deal, whereas conditional contracts require specific conditions to be met before obligations are triggered. While these other terms describe different characteristics of contracts, they do not specifically emphasize the reliance on uncertain future
