A deponent is a person who gives a sworn statement or testimony in the form of an affidavit or deposition. In legal terms, the deponent must state facts to which they can attest under oath, ensuring the truthfulness of the information provided. This is often used in court cases or legal proceedings where the deponent's testimony forms part of the evidence. The integrity and accuracy of a deponent's statement are critical as they are legally binding and can have significant implications in the judicial process.
