If the signature is inconsistent with the name of the ID card, it still has legal effect. For someone, in addition to the name on the ID card, there may be previous or commonly used names, which may be inconsistent with the name on the ID card, but as long as they are signed by themselves, they have legal effect, and the signer should bear corresponding legal responsibilities. In addition, when signing, try to confirm whether the names on the current ID card signed by the other party are consistent, or ask the other party to explain the situation to avoid unnecessary disputes.
