A legal oath is a formal promise made by an individual, often in a courtroom or during official proceedings, to tell the truth or fulfill certain duties. This oath is typically administered by a judge or authorized official and serves to ensure that the person understands the seriousness of their statements or responsibilities. In many legal systems, taking an oath is a requirement for witnesses, jurors, and public officials, including judges and lawyers. The act of swearing an oath is meant to uphold the integrity of the legal process and promote honesty in testimonies and actions.
