Matters needing attention when signing a contract:
1. First, the subject qualification of the other party should be verified.
2. If the other party to the contract is a natural person, it is necessary to verify, copy and save his/her identity documents to confirm his/her true identity and capacity. If the other party to the contract is a legal person, it is necessary to go to the local industrial and commercial department to inquire about its industrial and commercial registration information and inspect its company on the spot to determine its authenticity, verify whether the contractor is authorized by his company, and check its power of attorney, letter of introduction and contract. When signing the contract, it must be stamped with the official seal of the other party and the special seal for the contract.
3. Secondly, we should pay attention to the form of the contract.
4. The contract must be signed in written form. If the contract is signed orally, by letter or by data message, the confirmation letter must be signed and sealed, and the contract background should be marked when the contract is signed backwards.
6. Finally, it is necessary to pay attention to the specific and clear terms of the contract.
Under what circumstances is a contract invalid:
1. A contract concluded by one party by fraud or coercion that harms the interests of the state; Note: A contract concluded by one party through fraud or coercion belongs to a contract whose intention is untrue, and generally belongs to a contract that can be changed or cancelled. Only when it harms the national interests, it is an invalid contract.
2. Contracts that collude in bad faith and harm the interests of the state, the collective or a third party;
3. Contracts with legal forms to cover up illegal purposes;
4. contracts that harm the interests of the public;
5. Contracts that violate the mandatory provisions of laws and administrative regulations;
6. Contract clauses exempting the other party from personal injury or property loss caused by intentional or gross negligence.
7. The clauses that one party providing the standard clauses exempts the liability, aggravates the other party's liability and excludes the other party's main rights are invalid.
to sum up, the effectiveness of the agreement is related to the true will and legitimacy of the signature, while handprints are more related to traditional customs and specific industries. In modern legal practice, signature is usually regarded as an effective way to express will and can ensure the legal effect of the agreement. However, handprints may be required under certain circumstances, such as the regulations of some countries or specific industries. Therefore, whether the signature needs handprint to make the agreement effective should be determined according to the specific legal provisions and the requirements of the agreement. It is recommended to consult a professional lawyer for accurate legal advice before signing the agreement.
Legal basis:
Article 49 of the Civil Code of the People's Republic of China
If the parties conclude a contract in the form of a contract, the contract shall be concluded when all the parties sign and seal it 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 writing as stipulated by laws and administrative regulations or agreed by the parties. If the parties fail to do so in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
