Legality: an agreement not reached between the two parties is not applicable from the outset; a non-negotiable contract can only be implemented if the party whose option is cancelled cancels it. As long as this is avoided or revoked by the parties entitled by the exercise of its action, it is a valid contract. Talking about a null treaty is a contradiction in itself, because if a treaty is really null and void, it is not a treaty at all. An agreement that is not applicable by law is a non-agreement. A non-law contract must be distinguished from an inconclusive agreement. There are many ways to invalidate a contract. If a party is incompetent, it can no longer agree legally on a contract. This may mean that one of the people who enters into the contract when they are unable to act or that they are not in a position to make a correct judgment. A contract may also be cancelled due to the impossibility of its performance.
Like what. B if a contract is entered into between two parties A-B, but it is no longer possible to obtain the subject matter of the contract during the performance of the contract (due to the action of someone or other than the contracting parties), the contract cannot be obtained in court and is therefore unfagreested.  A void contract may be a contract in which one of the terms of a valid contract is absent/absent, for example.B. in the absence of contractual capacity, the contract may be considered null and void. In fact, it is not the case, it is that there is no contract. The law cannot impose any legal obligation on any of the parties, particularly the disappointed party, because it is not entitled to protection laws as long as they are contracts. 3. A cancelled contract does not end unless the party on the option from which it can be cancelled rejects it. But a no-deal is not valid from the beginning. Any contractual agreement between two parties for illegal activities is also deemed undated. For example, a contract between an illegal drug supplier and a drug dealer is not applicable from the outset because of the illegality of the agreed activity.
2. Determine precisely the laws and grounds for the nullity of the treaty. Empty contracts may arise if one of the parties is unable to fully understand the effects of the agreement. For example, a person with a mental disability or an intoxicated person may not be consistent enough to properly record the parameters of the agreement, rendering it invalid. In addition, agreements made by minors may be considered unseable; However, some contracts with minors who have obtained the consent of a parent or legal guardian may be enforceable. The terms „void” and „voidable” are often used interchangeably, but are of a completely different nature. While a non-contract contract is totally unenforceable by law, a cancelled contract is a valid contract. However, the terms of a cancelled contract provide that one or both parties entering into the contract have the option of cancelling the contract at any time. Voidable vs. Void Contracts A nonsense contract occurs if one of the parties had not originally accepted the contract, if he had known the true nature of all the elements of the contract prior to the initial acceptance. By presenting new information, the aforementioned party has the option of rejecting the contract after the fact.
2. Parties may, from the outset, be deemed unsigned by an agreement. On the other hand, a contract is terminated due to the subsequent impossibility or illegality of the service. Therefore, the party can only know them after the contract.
