Legal analysis: legal, must have their own autograph, whether to press the handprint is not a mandatory requirement of the law. But in reality, in most cases, I am required to press the fingerprint at the same time when I sign, and my failure to press the fingerprint will not affect the legal effect.

Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC). If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
