If the seal on the contract is not clear, the contract is not established without the signature or handprint of the signer, but the contract can be established with a clear seal next to it.

On the issue of stamping, we should pay special attention to three points:

1. The name of the company stamped with the official seal or special seal for the contract shall be exactly the same as the names of both parties to the contract;

2. The official seal of the unit or the special seal for the contract is an important document of the unit's external activities and shall not be lent out. If a contract is signed by borrowing the special seal of another unit, the contract is invalid, and the lending unit and the borrower shall be jointly and severally liable for the legal consequences of the invalid contract;

3. In order to prevent the agent from abusing his power of agency and signing the contract beyond his authority, it is generally necessary to sign the contract first and then seal it. Don't give the blank contract stamped with the official seal to the agent casually, otherwise the contract signed by the contractor with the blank contract stamped with the official seal will be borne by the unit.

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.

Relevant parties can put a clear seal next to it. If the parties conclude a contract in the form of a contract, the contract shall be established when both parties sign or seal it. The name of the company stamped with the official seal or special seal for the contract shall be exactly the same as the names of both parties to the contract. Unclear seals are prone to disputes and affect the effectiveness of the contract.

legal ground

People's Republic of China (PRC) Civil Code

Article 502 A lawfully formed contract shall become effective upon its formation, unless otherwise provided by law or agreed by the parties. In accordance with the provisions of laws and administrative regulations, if the contract should go through the approval procedures, such provisions shall prevail. If the failure to go through the formalities such as approval affects the effectiveness of the contract, it will not affect the performance of the obligation clauses such as approval and the effectiveness of relevant clauses in the contract. If the party that should go through the formalities for approval fails to perform its obligations, the other party may require it to bear the responsibility for violating its obligations. The modification, assignment and dissolution of a contract shall be subject to the provisions of laws and administrative regulations, and the provisions of the preceding paragraph shall apply and shall be subject to approval.
