what is the penalty of perjury
Generally, any legal system that requires the use of truth oaths or sworn statements may have a law against lying. If a statement, document, or other form of testimony is under penalty of perjury, it means it is a situation in which the laws of perjury apply. Anyone giving a deposition, testifying as a witness, primary party, or expert in a court case may be required to give an oath not to commit perjury.
