Oath of Office Law and Legal Definition
An oath of office is an oath or affirmation taken by a person before undertaking the duties of an office. In other words, oath of office refers to a formal and standard oath taken by persons who enter into a public office through election or appointment. It is a statement swearing to perform certain duties, represent the office ethically or other promises made before one or more witnesses. For example, the President of the U.S. swears to a standard oath that is sworn by all other presidents before him/her. This oath binds the parties to perform their duties cautiously and in good faith.
