Legal analysis: 1, as long as it is the true signature or handprint of the parties, it is valid and has the same legal effect, and they should bear legal responsibility.

Generally speaking, signing is enough, and it is better if you sign and press your fingerprint, which can prove the validity of the contract.

Legal Basis: the Supreme People's Court's Interpretation on Several Issues Concerning the Application of the People's Republic of China (PRC) Contract Law (II) Article 5 Where a contract is concluded in the form of a contract, the parties shall sign or seal it. If the parties press their fingerprints on the contract, the people's court shall determine that it has the same legal effect as the signature or seal.
