Legal analysis: the copy of the contract with official seal has legal effect. In terms of the validity of the contract, as long as both parties sign and seal, the contract will take effect and be legally binding, so the contract of electronic scanning or copying is also valid. 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.

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.
