The Doctrine of Consideration of the Contract in the Common Law and the Doctrine of Bilaterality of the Contract in the Civil Law

&nbsp;&nbsp;the modern contract law in the Anglo-American jurisprudence. The doctrine has been thought of taking its own position which is not found in the Civil Law tradition. The doctrine of consideration differentiates an enforceable contract from an unenforceable contract. The enforceablity of contract is examined by the bargain theory, the will theory, the reliance theory and the fairness theories. However, among those theories, the bargain theory only survived. A study on the doctrine of consideration under the bargain theory is much progressed in the Anglo-American jurisprudence while the bilaterality of contract, the counter part of the consideration, is not much studied in the Civil Law jurisprudence. The bilaterality of contract has been buried for a long time.<BR>&nbsp;&nbsp;However, a similar trace of the doctrine would be found in the bilateral contract in the Civil Law. To be consideration in a contract, a performance or a return promise must be bargained for. Also in bilateral contract in the Civil Law, a performance or a return promise must be bargained for. In this paper, I have examined the similarity and dissimilarity of both conceptions. I have concluded that the consideration of the Common Law is very similar to the bilateral aspect of Civil Law Contract, although some aspects are different from each other. The doctrine of consideration and the bilateral aspect of contract function to improve the certainty of contract because both conception make more clear the validity of agreements by testing the existences of consideration and bilaterality.
