legal analysis
according to relevant laws and regulations, as long as the parties sign and seal the contract, it has legal effect. In the real society, all kinds of legal documents require my signature to determine the validity. The name is a symbol of citizens and a formal expression of citizens' will and personality. An invalid contract is an established contract, but a contract that lacks effective elements is not legally binding and is not protected by national laws. If the subject of the contract is unqualified, which means that a person with no capacity for civil conduct or a person with limited capacity for civil conduct enters into a contract and the legal representative refuses to ratify it, the contract is invalid. A contract is the product of the parties' consensus, and it is an agreement in which two or more subjects express the same meaning. Under normal circumstances, only signature or seal can show the parties' recognition of the terms of the contract. However, if one party performs its obligations according to the contract and the other party accepts the obligations before the contract is signed or sealed, the contract will take effect. The entry into force of a contract requires certain conditions, and the entry into force of a contract can be divided into several categories: First, a contract established according to law takes effect upon its establishment. Second, in addition to the agreement of the parties, if the approval and registration procedures are required to take effect according to the provisions of laws and administrative regulations, they will take effect when the legal procedures are fulfilled. Third, although the contract is established, it can only take effect when it meets the effective conditions agreed by both parties or when the effective period agreed by both parties expires.
