What is the action of "swearing" in legal terms?

The action of "swearing" in legal terms refers specifically to putting someone under oath. This process involves an individual making a formal promise to tell the truth, often in a courtroom or during a legal proceeding. When a person is sworn in, they typically place their hand on a Bible or another sacred text (or make a solemn affirmation), signifying their commitment to honesty in their testimony or statements.

This process is essential because it holds the individual accountable. Failure to tell the truth while under oath can result in serious legal consequences, including charges of perjury. Swearing in is a critical part of many legal processes, as it enhances the integrity of the evidence or testimony being presented.

Other choices such as making a promise or signing a document lack the specific legal aspect associated with oath-taking. Affirming a statement is somewhat related but does not capture the complete legal implication of swearing under oath, which includes the associated penalties for dishonesty.
