What Is a Motion to Strike?
A Motion to Strike asks the court to delete specific portions of a pleading. Unlike a demurrer (which challenges entire causes of action), a motion to strike targets individual allegations, prayers for relief, or improper claims within an otherwise valid complaint.
Think of it as editing with a scalpel rather than a sledgehammer. The complaint might state valid claims, but contain improper requests (like punitive damages without malice allegations) or irrelevant inflammatory language that should be removed.
Often Filed Together
Motions to Strike are frequently filed alongside demurrers. You might demur to one cause of action while moving to strike punitive damages from another. They use the same timing rules and can be heard together.
Grounds for Motion to Strike (CCP 436)
Under CCP § 436, the court may strike any of the following from a pleading:
Irrelevant Matter
Allegations that have no bearing on the claims or defenses. Extraneous facts included just to prejudice the defendant. CCP 436(a)
False Matter
Allegations that are demonstrably untrue based on judicially noticeable facts or the complaint's own exhibits. CCP 436(a)
Improper Matter
Content not authorized by law — like punitive damages claims without allegations of malice, fraud, or oppression. CCP 436(b)
Non-Conforming Pleading
Pleadings that don't comply with court rules — wrong format, improper verification, or failure to follow local rules. CCP 436(b)
Common Targets for Motions to Strike
- Punitive damages — Must be supported by specific allegations of malice, oppression, or fraud (Civil Code § 3294)
- Attorney's fees — Only recoverable if authorized by contract or statute
- Scandalous allegations — Inflammatory language designed to embarrass or prejudice
- Redundant causes of action — Duplicative claims that add nothing
- Immaterial exhibits — Attachments that don't support the claims
Special Motion to Strike (Anti-SLAPP)
California's Anti-SLAPP statute (CCP § 425.16) provides a powerful "special motion to strike" for defendants sued based on protected speech or petitioning activity. This is different from a regular motion to strike.
Anti-SLAPP Benefits
If you win an anti-SLAPP motion, you're entitled to mandatory attorney's fees. Discovery is stayed while the motion is pending. It's a powerful tool for speech-related claims.
Anti-SLAPP Two-Step Analysis
- Protected Activity: Does the claim arise from defendant's exercise of free speech or petition rights in connection with a public issue?
- Probability of Success: If yes, can the plaintiff demonstrate a probability of prevailing on the claim?
If the defendant shows protected activity and the plaintiff can't show probability of success, the claim gets stricken and the defendant recovers fees.
60-Day Deadline
Anti-SLAPP motions must be filed within 60 days of service of the complaint. This deadline is strictly enforced. Miss it and you lose the right to this powerful remedy.
