Witness

What Is a Witness?

The term witness has two distinct legal meanings. A document witness observes another person signing a legal document and signs as proof that the execution occurred. A testimonial witness provides oral or written testimony in a legal proceeding about facts within their personal knowledge. Both roles are important to legal validity and the resolution of disputes.

Document Witnesses

Many legal documents require witnesses to be valid:

• **Wills**: most states require two disinterested witnesses for an attested will - **Deeds**: some states require one or two witnesses in addition to notarization - **Powers of attorney**: many states require witnesses for medical or durable powers - **Trust amendments**: requirements depend on the trust instrument and state law - **Contracts**: witnesses are not generally required but provide evidentiary value

Testimonial Witnesses

Witnesses in court proceedings may be classified as fact witnesses (testifying about what they personally observed) or expert witnesses (offering specialized opinions based on qualifications). Witnesses are typically required to take an oath or affirmation, are subject to direct and cross-examination, and must answer truthfully under penalty of perjury. The hearsay rule generally prohibits testimony about statements made by someone other than the witness, subject to numerous exceptions. Compelling testimony usually requires a subpoena, and witnesses are entitled to modest statutory fees for their appearance.
