What happens when a person supplies a witness deposition that person becomes a party to the lawsuit?

When a person supplies a witness deposition in a lawsuit, they do not automatically become a party to the case. A deposition is a sworn statement taken during the discovery phase, where a witness provides testimony relevant to the case. However, if the witness is later called to testify as a party or if their testimony significantly impacts the case, they may become more involved in the proceedings. In some situations, the party supplying the deposition may also face legal consequences if the testimony is disputed or leads to further claims.
