Legal analysis: If the signature is inconsistent with the name on the ID card, it is still legally valid. For a certain person, in addition to the name on the ID card, there may also be a previous or common name, which may be inconsistent with the name on the ID card. However, as long as it is signed by the person himself, it has legal effect. The signatory must Bear corresponding legal responsibilities. In addition, when signing, you should try your best to confirm that the name on the other party's signature is consistent with the name on the ID card, or ask the other party to explain the situation to avoid unnecessary disputes.

Legal basis: Article 490 of the "People's Republic of China and Civil Code" Where the parties conclude a contract in the form of a contract, the contract is established when both parties sign, seal or fingerprint. Before signing, sealing or fingerprinting, one party has performed its main obligations and the contract is established when the other party accepts it. Laws and administrative regulations stipulate or the parties agree that a contract should be concluded in written form. If the parties do not use written form but one party has performed its main obligations and the other party accepts it, the contract is established.
