When you say "the boss forces the employee to sign someone else's name on the contract", the contract is invalid or valid but the actor bears the responsibility.

First, generally speaking, if you sign someone else's name privately, you should bear the responsibility yourself.

Article 48 of the Contract Law: A contract concluded by the actor in the name of the principal has no power of agency, exceeds the power of agency or is terminated, so it is not valid for the principal, and the actor shall bear the responsibility.

Second, in the case of fraud, coercion or damage to the interests of the state or a third party, refer to the following provisions.

Article 52 of the Contract Law is invalid under any of the following circumstances: (Invalid Contract)

(1) One party enters into a contract by means of fraud or coercion, which harms the interests of the state;

(2) Malicious collusion that harms the interests of the state, the collective or a third party;

(3) Covering up illegal purposes in a legal form;

(4) damaging the public interest;

(5) Violating the mandatory provisions of laws and administrative regulations.

Article 54 One party has the right to request the people's court or arbitration institution to modify or cancel the following contracts: (Cancelled and modifiable contracts)

(1) Due to a major misunderstanding;

(2) obviously unfair at the time of conclusion of the contract.

If one party leads the other party to conclude a contract against its true meaning by fraud, coercion or taking advantage of others' danger, the injured party has the right to request the people's court or arbitration institution to modify or cancel it. (This clause is different from an invalid contract: one party concludes a contract by means of fraud or coercion, which harms the interests of non-state; Invalid contracts are detrimental to national interests)

The people's court or arbitration institution shall not revoke the request of the parties.
