The forcible inducement to an act.
Compulsion may be lawful or unlawful. 1. When a man is compelled by lawful authority to do that which be ought to do, that compulsion does not affect the validity of the act; as for example, when a court of competent jurisdiction compels a party to execute a deed under the pain of attachment for contempt, the grantor cannot object to it on the ground of compulsion. 2. But if the court compelled a party to do an act forbidden by law, or not having jurisdiction over the parties or the subject-matter, the act done by such compulsion would be void.
Compulsion is never presumed.
