Where would you file a notice of taking deposition as a pleading or discovery file?

A notice of taking deposition is typically filed as part of the discovery process rather than as a pleading. In most jurisdictions, it should be filed with the court where the case is pending, often in the discovery file or section of the court's electronic filing system. Additionally, a copy of the notice should be served on all parties involved in the case. Always check local rules for specific filing requirements.
