Demurrers and Motions to Strike Explained

Not every civil case proceeds directly into discovery. Before evidence is exchanged, defendants may challenge the legal sufficiency of a complaint. Two common procedural tools used at this stage are demurrers and motions to strike.

These mechanisms allow courts to evaluate whether a pleading meets required legal standards before the case moves forward.

What a Demurrer Challenges

A demurrer argues that the complaint does not state facts sufficient to constitute a valid cause of action. The court assumes the factual allegations are true for purposes of the analysis.

The issue is not whether the events occurred, but whether those alleged facts amount to a legally recognized claim under existing law.

Grounds for Filing a Demurrer

Demurrers may be based on several grounds, including failure to state a claim, lack of jurisdiction, or uncertainty in the pleading.

The court reviews only the face of the complaint and matters that are properly subject to judicial notice.

What Happens If a Demurrer Is Sustained

If the court agrees with the challenge, it may sustain the demurrer. In many instances, the plaintiff is given leave to amend and correct the deficiencies.

If the court sustains the demurrer without leave to amend, the affected claim may be dismissed entirely.

How a Motion to Strike Differs

A motion to strike targets specific portions of a pleading rather than the entire cause of action. It may seek removal of improper damage requests or legally unsupported allegations.

Unlike a demurrer, which challenges overall legal sufficiency, a motion to strike narrows or removes particular components of the complaint.

These Tools Shape the Scope of Litigation

Demurrers and motions to strike function as early filters. They clarify which claims may proceed and which must be revised or eliminated.

By resolving pleading deficiencies at the outset, courts promote efficiency and focus the dispute on legally viable issues.

Early Challenges Influence Case Strategy

Because these motions occur at the beginning of litigation, they can affect settlement posture, amendment strategy, and the overall trajectory of the case.

Understanding how these procedural tools operate helps explain why some cases are refined or dismissed before substantive litigation begins.
