[1][2] For example, gambling, wagering, or betting, typically use aleatory contracts.
Additionally, another very common type of aleatory contract is an insurance policy.
[1] The term was a classification that was developed in later medieval Roman law to cover all contracts whose fulfilment depended on chance, including gambling, insurance, speculative investment and life annuities.
[3] The French civil code contains a chapter on aleatory contracts, with specific provisions for gaming (gambling) and life annuities.
Many modern forms of derivatives and options may in some cases also be considered aleatory contracts.
