When the motion to quash or modify a subpoena is used
Timing: promptly — the motion must be timely. Discovery is the stage where the parties exchange information. In most federal cases it follows the Rule 26(f) conference.
What the rule requires
- On timely motion, the court must quash or modify a subpoena that fails to allow a reasonable time to comply; requires a person to comply beyond the geographical limits in Rule 45(c); requires disclosure of privileged or other protected matter if no exception or waiver applies; or subjects a person to undue burden (Rule 45(d)(3)(A)).
In practice, read each requirement closely. Then check whether your court adds anything of its own. For example, many courts set page limits, formatting rules or a duty to confer with the other side first.

However, the name, the deadline and the required form can differ. Therefore, look up the matching rule in your state’s rules of civil procedure. Also read your court’s local rules.
