Art. 6:228 of the Dutch Civil Code provides that a contract concluded under the effect of an error is cancelled if a number of conditions are met. One of the conditions is that the wrong party would not have concluded the contract, but for the error. Another condition is that the other party be allowed or should have known the circumstances of the error and that it was obliged to inform the wrong party. It is essential that not all errors are enough to invalidate a contract, for example. B errors that relate only to future circumstances or errors regarding the nature of the agreement are not sufficient. The Indian Contracts Act is governed by the Indian Contract Act of 1872. However, the Contract Act does not codify the entire law of contracts, the law also expressly preserves any use or use of trade or any incident of a contract that is not inconsistent with the provisions of the law. Contract law is limited to the application of voluntary civil obligations. Contract law is not able to deal with the full range of agreements, many agreements remain outside the jurisdiction because they do not meet the requirement of a contract. A contract is an agreement; An agreement is a promise and a promise is a proposal adopted.

Any agreement is therefore the result of a proposal on the one hand and its adoption on the other. A contract is considered a contract if it is legally applicable. Section 10 of the Act deals with the conditions of enforceable force, according to this section, a contract is a contract when it is made for consideration, between the parties who are competent for the contract, with free consent and for a legitimate purpose. 2.
