What Is a Discovery Motion? Types, Process & Legal Impact in Civil Cases

Illustration of a discovery motion - highlighting how courts resolve disputes over evidence during the discovery phase of civil litigation.

In civil litigation, both parties have a legal duty to share relevant information during the discovery phase. But what happens when one side refuses to cooperate? That’s when a discovery motion comes into play.

A discovery motion is a formal request filed with the court when parties disagree about the exchange of evidence. It’s typically used when one party refuses to provide documents, gives incomplete responses, or objects without proper legal basis. The goal is simple: ensure a fair and transparent discovery process.

How Discovery Motions Work (Step-by-Step)

1. Discovery Phase Begins

Once litigation starts, both sides request information from each other. This can include:

• Interrogatories (written questions)

• Requests for Production (documents and records)

• Requests for Admissions (confirming facts)

• Depositions (sworn statements)

2. A Dispute Arises

Sometimes, one party might:

• Refuse to hand over documents

• Provide vague or incomplete answers

• Miss deadlines or object unnecessarily

3. Filing a Discovery Motion

If informal attempts to resolve the issue fail, the requesting party may file a motion—usually a motion to compel—asking the judge to order the other side to comply.

Common Types of Discovery Motions

Understanding which motion to file is key. Here are the most common types used in civil cases:

1. Motion to Compel Discovery

Filed when the opposing party fails to respond, gives incomplete answers, or ignores deadlines. This motion asks the court to enforce compliance and compel the party to turn over the requested information.

2. Motion for Protective Order

Filed to shield a party from excessive or inappropriate discovery requests. This motion seeks to:

• Limit the scope or timing of discovery

• Prevent harassment

• Protect sensitive or confidential data

3. Motion to Quash

Used to invalidate (quash) a subpoena or discovery request. Grounds include:

• The request is irrelevant or overbroad

• It’s directed at the wrong party

• It imposes an undue burden

Final Thoughts

Discovery motions are essential tools in civil litigation. They protect the rights of both parties and help maintain fairness throughout the process. If your legal team is navigating a dispute during discovery, filing the correct motion at the right time can make all the difference.
