Effective, in fact, signature and handprint are the legal proof basis, and the legal effect is the same. When signing a contract, signature, seal and handprint all have the same legal effect. Therefore, as long as it is the personal signature of the party concerned, it is legally effective to press the handprint or not. If the other party goes back on his word, he can bring a lawsuit to the court, and then the signature will be authenticated by a professional handwriting signer. Article 490 of the Civil Code stipulates that if the parties conclude a contract in the form of a contract, the contract is 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.
