The labor contract does not have to be sealed, but it is legally effective without the official seal of the employer but with the signature of the relevant person in charge. If there is no seal, the employee may ask the employer to sign and affix the official seal when signing the labor contract.

Legal objectivity:

Article 490 of the Civil Code of People's Republic of China (PRC): If the parties conclude a contract in the form of a contract, the contract is concluded 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.
