Legal analysis: doesn't the house lease contract take effect according to the fingerprint? If the leased house does not take effect according to the fingerprint, but the parties sign or seal it, the lease contract is established, and the legally established lease agreement has legal effect. Fingerprinting is to strengthen confirmation, not a necessary procedure. Handprints can't be copied, and important contracts should be printed on key parts to prevent fraud. Handprint and signature have the same effect, so the parties can use handprint instead of signature, and the contract based on handprint is also valid, but it is suggested that when signing the contract, they should sign their own relevant names as much as possible.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 143 A civil juristic act that meets the following conditions is valid: (1) The actor has corresponding capacity for civil conduct; (2) the meaning is true; (three) does not violate the mandatory provisions of laws and administrative regulations, and does not violate public order and good customs.

Article 490 Where the parties conclude a contract in the form of a contract, the contract is formed when the parties sign, seal or fingerprint 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 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.
