There are plenty of synonyms one can use to describe sworn testimony. Some of these terms are legal jargon while others are more straightforward, but all generally convey the same meaning. Examples include depositional evidence, sworn statement, affidavit, witness statement, under-oath testimony, and sworn declaration. Despite the slight variations in phrasing, each of these terms underscores the importance of credibility and honesty in legal proceedings. When given under oath, testimony serves as a binding agreement that the witness will tell the truth, the whole truth, and nothing but the truth. Regardless of which synonym one uses, it implies an obligation to uphold the veracity of the proceeding.
