You mean you work for the defendant, and then you sign the delivery note between the defendant and the plaintiff. Do you need to bear legal responsibility?

Article 34 of the Tort Liability Law: If a staff member of an employer causes damage to others due to the performance of work tasks, the employer shall bear the tort liability.

Article 35 If a labor relationship is formed between individuals, and the party providing labor services causes damage to others due to labor services, the party receiving labor services shall bear the tort liability. If the party providing labor services suffers personal injury, it shall bear corresponding responsibilities according to the respective faults of both parties.

According to the law, the defendant shall bear the responsibility for disputes between the defendant and others.

However, if the dispute between you and the defendant is your responsibility, you should bear it yourself.
