The key idea is that a witness’s testimony becomes evidence only when it is given under oath or affirmation. The oath is the formal promise to tell the truth, and it ties the witness to honesty by subjecting them to penalties for perjury if they lie. Because of that sworn commitment, courts treat sworn testimony as reliable enough to be admitted and weighed in deciding the case. Informal, unsworn statements generally don’t carry the same evidentiary weight and aren’t freely admissible as evidence in court. In civil proceedings, you typically rely on sworn testimony—whether spoken in court or given in a deposition under oath—or on other sworn written statements like affidavits. However, testimony is not required to be written; it can be oral in court or via deposition, and sworn written statements are a separate form of evidence. So the true statement is that witnesses’ testimony must be offered under oath or affirmation to be admissible as evidence.
