Due to the practical advantage and economic interest of the standard contracts, it is used more than individual contracts in today's commercial life. The widespread use of such contracts also includes some legal problems. In this study, the concept of battle of forms, which is one of these problems, and the legal consequences related to this situation will be examined in the light of comparative legal knowledge. In the course of concluding the contract, if the parties refer to their own standard contract provisions, the issue of whether they will be applied together or which will be preferred is expressed in various ways as "battle of forms", in doctrine. For the solution of this problem, the first shot rule, the last shot rule, the knockout rule, the best shot rule, and the reasonable shot rule will be mentioned. In this study, legal consequences related to the conflict of standard contract provisions in English, American and Turkish Law, especially in terms of CISG, PECL and PICC, in terms of international conventions and national laws will be discussed. Conflict of standard contract terms is not clearly regulated in country law. Some of the international agreements do not include a separate regulation. So there is any solution for this problem in many countries. We will explain solution for this problem with respect to the regulations in national and international law. Especially in cases where there is no legal regulation, the suggestions suggested in the doctrine can be used for the solution of the problem.
