Legal analysis: Generally, the official seal of a company will be filed in the Industrial and Commercial Bureau, but the contract seal is generally not filed. However, if the company uses the same official seal when signing the contract with the employer, it can be considered as the company's behavior, and the company will bear the responsibility. You can go to other companies with cooperative projects in this company to find a suitable way. Secondly, the special invoice seal, official seal, financial seal and contract seal all need to be put on record, and the special contract seal and official seal should be put on record at the public security organ. If not put on record, there may be disputes related to the authenticity of the seal, so the special contract seal can go to the public security organ to check the record.

Legal basis: Article 490 of the Civil Code of the People's Republic of China stipulates that if the parties conclude a contract in the form of a contract, the contract will be formed when all the parties sign, seal or fingerprint it.
