The impossibility of performing an act does not create an obligation for the parties. Section 56 of the Act invalidated such a contract. This section clarifies that if transactions resulting from an unlawful act are designed in such a way that, if separated from the illegal party, they would constitute a valid agreement, such transactions remain valid and can be implemented regardless of the illegality of the agreement.  An agreement that was not concluded from the beginning is considered to be from the beginning. To be valid, the agreement must contain all the elements listed in the Indian Contracts Act, 1872, section 10. From the beginning, ab-initio agreements violated the Indian Contracts Act and are not valid. Examples of an agreement that would never be valid are as follows: a frequent example of an invalid contract is one in which an actor accepts a series of shows, but gets injured and cannot perform. Under these conditions, the contract was initially valid, but it is no longer applicable. A cancelled contract is a contract that totally lacks legal effect. A contract is cancelled if: This section provides that an agreement is considered to be an agreement not concluded, unless it is covered by the following exceptions:- it must, however, be distinguished from the imposition of a penalty in the event of remarriage. The penalty for remarriage is not considered a restriction on marriage.
So, if an agreement has been reached between two members, that if one of them marries, the other must renounce his share in the fortune of the deceased husband. Another way to invalidate agreements is uncertainty. If an agreement is not clear as to its importance and cannot be clarified by legal or commercial procedures, the agreement is concluded in nullity. Part of what constitutes a legally binding treaty is the obligation to be clear and therefore to be able to be respected.
