a comparative study of analysis of the nature of aleatory contract in iran and ejipt law.

Aleatory contract has not been codified in Iran''s regulations. Whereas Egypt''s regulations not only generally compromise aleatory contract but also give prominent examples for it. In Aleatory contracts considerations are not determined، because، here، determination of a consideration is based on some factors which will be fulfilled in the future. The effect of this contract shall be established at the time of conclusion of contract; so this contract is absolutely distinguished from the suspended contract. Risk is not effective to this contract; so aleatory contract is basically distinguished from risk contract as well. Ultimately aleatory contract has different concepts in comparison with deferred contract and conditional contract. With dependence on profiteering intentions of parties، this contract has deceptive characteristics. With respect to dependence of contract''s effect on tense factor، it has continuous characteristic inhere. Also this contract is one of obligatory contracts which has non-simultaneous obligations. Unexceptional characteristic is another characteristic of these contracts. Profiteering intention cause to deceptive characteristic in this contract and dependence of cotract''s effect on tense cause to continuous characteristic inhere. Aleatory contract is one of obligatory contract which has simultaneous obligations. Unexceptional characteristic is another characteristic of these contracts.
