Signing an agreement is only valid if it is signed without fingerprints. In general, if a contract is concluded in the form of a contract, it is valid if both parties sign, seal or press fingerprints. However, if it is stipulated in the contract that it is only valid if both parties sign and press fingerprints, it is invalid if the contract is signed without fingerprints. Legal objectivity:

Article 49 of the Civil Code of the People's Republic of China * * * If the parties conclude a contract in the form of a contract, the contract shall be formed when all the parties have signed, sealed or fingerprinted it. 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 writing as stipulated by laws and administrative regulations or agreed by the parties. If the parties fail to do so in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
