An aleatory contract is a contract where an uncertain event determines the parties' rights and obligations.[1][2] For example, gambling, wagering, or betting typically use aleatory contracts. Additionally, another very common type of aleatory contract is an insurance policy.[3][4]

The term was a classification developed in later medieval Roman law to cover all contracts whose fulfilment depended on chance, including gambling, insurance, speculative investment and life annuities.[5] Many modern forms of derivatives and options may in some cases also be considered aleatory contracts. For example, the French civil code contains a chapter on aleatory contracts, with specific provisions for gaming (gambling) and life annuities.[6]
