What Are Discovery Motions in California?

First, definitions.

Recall that a motion is an application for an order. Basically, you’re asking a California judge to do something. See CCP § 1003.

Discovery refers to the process in litigation when both parties exchange information by responding to questions or requests for information..

A discovery motion is a motion about discovery.

What are the Types of Discovery Motions?

There are three types of discovery motions:

  • Motion to compel discovery (when the other side fails to respond at all)
  • Motion to compel further discovery (when the other side fails to adequately respond)
  • Motion to deem Requests for Admissions Admitted (when the other side fails to timely respond to your requests for admission)

What is a Motion to Compel Discovery?

It’s a motion you file when the other side fails to provide any discovery responses at all, or fails to serve discovery responses with verifications.
