Rule 29 permits parties to modify the procedures set forth in the Federal Rules of Civil Procedure through mutual agreement. This rule allows for flexibility in how depositions are conducted, including the use of remote methods. Parties can stipulate to various aspects of the deposition process, such as the time, place, manner, and method of recording, including agreeing to conduct the deposition remotely. This rule underscores the importance of mutual consent in modifying traditional deposition procedures to fit remote formats.
