Witness
Definition:
A Witness is an individual who provides testimony or evidence in a legal proceeding based on their personal knowledge, observation, or expertise. Witnesses help the court establish facts by giving sworn statements or testifying under oath during trials, hearings, or depositions. Their role is essential in ensuring that legal decisions are based on credible and verified information.

Witness Information
A **Witness** may be anyone who has direct knowledge of facts relevant to a case or transaction. There are several types of witnesses, including **eyewitnesses** (who personally observed events), **expert witnesses** (who provide professional opinions), and **character witnesses** (who testify about a person’s reputation or behavior). In legal documents, witnesses may also attest to signatures on contracts, wills, or deeds, verifying that the signing occurred willingly and with proper understanding. Witness testimony must be truthful, and giving false testimony under oath—known as **perjury**—is a criminal offense. The credibility and reliability of witnesses often play a key role in determining the outcome of legal cases.
Florida Legal Definition
Under **Florida law**, a **Witness** is any person who gives testimony under oath or affirmation regarding facts or events within their knowledge. Florida Statutes, such as **Section 90.601 of the Florida Evidence Code**, establish that every person is competent to be a witness unless otherwise provided by law. In addition, Florida requires witnesses in specific legal instruments—for example, **wills** must be signed in the presence of two witnesses under **Section 732.502, Florida Statutes**. In court proceedings, witnesses must take an oath or affirmation to tell the truth, and their credibility can be challenged through cross-examination and impeachment under the rules of evidence.
How It’s Used in Practice
In practice, **Witnesses** play a vital role in Florida’s judicial and transactional processes. In court, witnesses testify to establish facts, clarify timelines, or support expert opinions. In real estate or estate planning, witnesses are required to verify the authenticity of signatures on deeds, contracts, and wills. For example, a Florida notary or two witnesses might observe and sign a deed transfer to confirm the parties acted voluntarily. Attorneys carefully prepare witnesses before trial to ensure accurate and consistent testimony. The weight and credibility of witness statements often influence judges and juries in determining the truth.
