When the motion to compel discovery is used
Timing: after a party fails to disclose or respond. Discovery is the stage where the parties exchange information. In most federal cases it follows the Rule 26(f) conference.
What the rule requires
- The motion must include a certification that the movant has in good faith conferred or attempted to confer with the person or party failing to make disclosure or discovery (Rule 37(a)(1)).
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.
