What is the legal effect of signing a contract?

1. Is the contract signed by others without the signature of the client legally effective?

In this case, it can be ratified afterwards. The validity of the contract remains to be determined. If the parties do not approve, the agreement is invalid. Of course, if the ghostwriter has the plot of agency by estoppel, the contract is still valid. So this situation is more complicated.

Second, what is an agency contract?

Principal-agent refers to a civil legal act that an agent carries out in the name of the principal according to the entrustment of the principal. Its effectiveness directly belongs to the client. There are two main forms of agency, namely written form and oral form. In practice, the parties may adopt oral form or written form. However, if the law requires it to be in writing, it shall be in writing in accordance with the law, such as litigation agent, signing economic contracts on behalf of others, etc.

3. What is the legal responsibility of the agency contract?

1. The agent and the principal shall be jointly and severally liable. If the power of attorney is unclear, the client shall bear civil liability to the third party, and the agent shall bear joint liability. If the principal carries out agency activities knowing that the entrusted matters are illegal, the principal and the agent shall bear joint and several liability.

2, the agent does not perform the agency duties, damage the interests of the principal's responsibility. If an agent engages in civil activities with himself or others in the name of the principal and causes losses, he shall bear civil liability. In fact, this situation is the arbitrary agency behavior of the agent. If an agent colludes with a third party and damages the interests of the principal, the third party shall be jointly and severally liable.

3. No right to represent the liability for damages. Without agency, beyond agency or after the termination of agency, the principal will bear legal responsibility only after ratification by the principal. If the act is not ratified, the actor shall bear legal responsibility. Knowing that someone else has committed a civil act in my name without denying it is regarded as consent. If the third party knows that the actor has no agency; If the third party and the actor commit civil acts and cause losses to others after exceeding the agency right or terminating the agency right, they shall be jointly and severally liable with the actor.

In order to safeguard the principal's interests, the agent may delegate the power of agency he has obtained to others. Where an agent is entrusted to another person, the consent of the principal shall be obtained in advance. Without the prior consent of the client, the client shall be informed in time afterwards. If the principal does not agree, the agent shall bear legal responsibility for the behavior of the principal. However, in case of emergency, in order to protect the interests of the client, this restriction is not applicable.

4. What kind of agency contract is invalid?

An invalid contract concluded by an invalid agent includes the following situations:

1. A contract concluded by an unauthorized agent without ratification by the principal;

2. The contract signed by the agent with himself in the name of the principal;

3. The contract signed by the agent in the name of the principal and other people he represents;

4. The contract signed by the agent and Party A that harms the interests of the client.

In short, a contract signed by someone else without the client's signature depends on whether the signatory has an appointment relationship. After ratification, the contract is valid, and if the parties do not recognize it, the agreement is invalid.
