In California, malicious prosecution is a civil claim you can bring against someone who put you through a baseless lawsuit or criminal case, but winning requires proving five specific things and getting past an early procedural test that can leave you paying the other side’s legal fees. You must show the defendant brought a case against you, that it ended in your favor, that it was filed without probable cause, that the defendant acted with malice, and that you suffered harm.1Justia. California Civil Jury Instructions (CACI) No. 1501 – Wrongful Use of Civil Proceedings Miss any element and the whole claim fails.
The Case Must Have Ended in Your Favor
The prior case’s ending has to reflect on the merits. A not-guilty verdict, a judgment for you in a civil case, or a prosecutor’s dismissal of charges all qualify. The outcome needs to suggest the underlying claims lacked substance or that you were innocent.
Not every ending counts. A dismissal on a procedural technicality — improper service, a jurisdictional defect — usually won’t work because it says nothing about the merits. Settlement is worse: if you settled the underlying case before a judgment, you generally can’t bring a malicious prosecution claim later, because there’s no outcome that reflects on whether the claims had merit.
There Was No Reasonable Basis for the Original Case
You have to show the prior action was filed without probable cause. Under Sheldon Appel Co. v. Albert & Oliker, the test is objective: would any reasonable attorney, knowing the same facts, have thought the claim was legally tenable?2Justia. Sheldon Appel Co. v. Albert and Oliker (1989) If the answer is no, probable cause was lacking.
When the underlying facts aren’t in dispute, the judge decides this question, not a jury. The analysis also runs claim by claim. If the original suit had five causes of action and only one was baseless, that single claim can support your case.
The Defendant Acted With Malice
Malice means the original case was filed for a wrongful purpose rather than a legitimate one. Suing to harass, to force settlement on an unrelated dispute, or to damage a competitor’s reputation all qualify. The purpose doesn’t need to be dramatic; it just needs to be something other than an honest attempt to win on the merits.
Direct evidence of a bad motive is rare. Juries are allowed to infer malice from surrounding circumstances, and the strongest inference comes from the absence of probable cause itself. If no reasonable person would have thought the case had merit, a jury can conclude the real motive was improper.1Justia. California Civil Jury Instructions (CACI) No. 1501 – Wrongful Use of Civil Proceedings
The Anti-SLAPP Motion Comes First
This is where many California malicious prosecution claims die. The state’s anti-SLAPP statute protects people from lawsuits that punish them for exercising their right to petition the government, and filing a lawsuit counts as petitioning activity.3California Legislative Information. California Code of Civil Procedure 425.16 So almost every malicious prosecution suit draws an anti-SLAPP motion.
The motion runs in two steps. First, the defendant shows that the conduct you’re suing over — filing the earlier case — is protected activity. For malicious prosecution, that’s almost automatic. Second, the burden shifts to you: you must present admissible evidence showing a probability you’ll prevail on each element. Favorable termination, no probable cause, malice — all of it, up front, before discovery has run its course.
The financial exposure is real. If the defendant wins the anti-SLAPP motion, they are entitled to recover their attorney fees and costs from you.3California Legislative Information. California Code of Civil Procedure 425.16 Those fees routinely reach tens of thousands of dollars. Treat the anti-SLAPP motion as the first real battle. If your evidence isn’t strong enough to survive it, you’ll walk away worse off than when you started.
Who You Can Sue
The obvious defendant is the person or company that filed the baseless case. Liability can extend further.
The Opposing Attorney
The lawyer who handled the prior case can also be a defendant. Attorney liability generally requires showing the lawyer knew the case had no legal basis and pressed forward anyway, or continued prosecuting claims after learning they were unfounded. Losing on a close call isn’t enough; this targets attorneys who ignored obvious problems or actively used litigation as a weapon.
Government Prosecutors
Suing a prosecutor for a bad criminal case is different. Prosecutors have absolute immunity for actions taken as part of the judicial process, including the decision to file charges and how to conduct the case. Motive doesn’t matter. Even a prosecutor who knowingly brought baseless charges out of personal spite is shielded from a state-law malicious prosecution claim.
What You Can Recover
California recognizes three categories of damages in a successful malicious prosecution case.1Justia. California Civil Jury Instructions (CACI) No. 1501 – Wrongful Use of Civil Proceedings
Economic damages cover direct financial losses. The attorney fees and costs you paid defending the original case are the biggest category, and they can be substantial when the prior case stretched on for months or years. Lost wages, lost earning capacity, and damaged business relationships also qualify if you can document them.
Non-economic damages cover the personal toll: emotional distress, damage to reputation, and the humiliation of having baseless allegations in public court records. Juries have broad discretion here, and awards track the severity and duration of the harm.
Punitive damages are available in especially egregious cases. You must prove by clear and convincing evidence that the defendant’s conduct was malicious, fraudulent, or oppressive under California Civil Code section 3294.4Justia Law. California Civil Code 3294-3296 – Exemplary Damages That’s a higher bar than the malice required for the underlying claim, so punitive damages are far from automatic even when you win.
You Have Two Years to File
California applies a two-year statute of limitations under Code of Civil Procedure section 335.1.5California Legislative Information. California Code of Civil Procedure 335.1 The clock starts when the underlying case ends in your favor, not when it was originally filed against you. If the prior case went up on appeal, the period doesn’t start running until the appeal is resolved.
Two years sounds generous. It isn’t. You need strong evidence of probable cause and malice assembled before you file, because the anti-SLAPP motion will demand it within weeks of filing. Waiting until month 23 to start preparing produces either a missed deadline or a weak case that gets struck down with fees against you.
How This Differs From Abuse of Process
These two claims often get confused. Malicious prosecution targets someone who filed a meritless case against you for an improper reason. Abuse of process targets someone who misused a specific legal tool inside a case that may have been properly filed.6Justia. California Civil Jury Instructions (CACI) No. 1520 – Abuse of Process – Essential Factual Elements
Classic abuse of process involves things like weaponizing discovery to harass an opponent, obtaining an excessive attachment to pressure a settlement, or subpoenaing records for a purpose unrelated to the litigation. The original suit itself might have been fine; the wrong lies in how a particular tool got twisted. Because abuse of process doesn’t require the case to have ended, favorable termination isn’t an element. If your problem is a meritless case brought to harm you, malicious prosecution fits. If your problem is a legitimate case where a specific procedural device was misused for an ulterior purpose, abuse of process may be the better claim.
When the Bad Actor Is a Government Official
When a police officer initiates a criminal prosecution against you without probable cause, state-law malicious prosecution may be blocked by immunity. A federal civil rights claim under 42 U.S.C. § 1983 can sometimes fill that gap. These claims rest on the Fourth Amendment’s protection against unreasonable seizures rather than state tort law.
In Thompson v. Clark (2022), the U.S. Supreme Court held that a plaintiff bringing a Fourth Amendment malicious prosecution claim only needs to show the criminal case ended without a conviction, not that the outcome affirmatively indicated innocence.7Cornell Law School. Thompson v. Clark That’s a lower bar than California’s favorable-termination requirement. You still have to prove there was no probable cause, work around qualified immunity, and — in the Ninth Circuit, which covers California — prove malice as part of the analysis.
