A contract may also be null and void due to the impossibility of performing it. For example, when a contract is concluded between two A&B parties, but the object of the contract becomes impossible during the performance of the contract (due to acts of someone or other parties), the contract cannot be enforced in court and is therefore anniged.  An unincluded contract may be a contract in which one of the terms of a valid contract is missing, for example. B in the absence of contractual capacity, the contract may be considered null and void. Indeed, this means that a treaty does not exist at all. The law cannot impose a legal obligation on one of the parties, in particular on the disappointed party, since it is not entitled to protective laws insofar as they are contracts. A cancelled contract cannot be enforced by law. Contracts not concluded are different from countervailable contracts, which are contracts that may be cancelled. However, when a contract is written and signed, there is not, in all situations, an automatic mechanism that can be used to determine the validity or applicability of that contract. In practice, a contract can be cancelled by a court.
 The main question is therefore under what conditions can a contract be considered inconclusive? An agreement for the performance of an illegal act is an example of an invalid agreement. For example, a contract between drug traffickers and buyers is a void contract simply because the terms of the contract are illegal. In such a case, neither party can go to court to enforce the contract. An agreement not concluded is not concluded from the outset, that is: From the outset, whereas a countervailable contract may be challenged by either party. A countervailable contract is not cancelled at the outset, but later becomes invalid due to certain changes in condition. Overall, there is no margin of appreciation between the contracting parties in the case of an unde concluded contract. The parties are not entitled to enforce a non-binding contract. . . .
