Equitable Tolling in California: Requirements and When It Applies

Equitable tolling in California is a judge-made rule that pauses the statute of limitations when a plaintiff has been diligently pursuing the same claim through another legal channel, such as the wrong court or a required administrative process. It is discretionary, not automatic, and the plaintiff carries the burden of proving they deserve the pause. The California Supreme Court set the framework in Addison v. State of California in 1978, and courts still apply the same three-part test: timely notice to the defendant, no prejudice to the defendant, and reasonable, good-faith conduct by the plaintiff.1Supreme Court of California. Saint Francis Memorial Hospital v. State Department of Public Health

That makes it different from statutory tolling, which operates mechanically under code sections like Code of Civil Procedure 351 and 352. Those provisions stop the clock automatically when the defendant leaves the state or the plaintiff is a minor or lacks capacity, with no showing of diligence required.2California Legislative Information.

The Three Requirements

Later decisions, especially McDonald v. Antelope Valley Community College District, filled in what each Addison element actually demands.4Stanford Law – Supreme Court of California. McDonald v. Antelope Valley Comm. College All three have to be present. Fail one and tolling is unavailable.

Timely Notice to the Defendant

The defendant in the later lawsuit must have learned about the plaintiff’s claim within the original limitations period. In practice, that means the first proceeding, whether in the wrong forum or before an agency, has to be filed before the deadline runs and has to alert the defendant to the underlying facts so the defendant knows to start preserving evidence and investigating. Usually the defendant in both proceedings is the same party, but courts have found this element satisfied even when it is not, so long as the defendant knew the relevant facts.5Justia. CACI No. 457 – Statute of Limitations – Equitable Tolling – Other Prior Proceeding

No Prejudice to the Defendant

The time spent on the first proceeding cannot leave the defendant materially worse off in defending the second one. Courts look at whether evidence was lost, witnesses became unavailable, or the delay otherwise made a fair defense harder. When timely notice is clear, this element is often satisfied almost automatically, because a defendant who knew about the claim early had every chance to preserve what it needed.1Supreme Court of California. Saint Francis Memorial Hospital v. State Department of Public Health

Reasonable and Good-Faith Conduct

This is where most tolling arguments win or lose. The plaintiff’s conduct has to be objectively reasonable and subjectively in good faith. Reasonableness looks at whether the plaintiff’s choices made sense given the circumstances. Good faith looks at whether any late filing stemmed from an honest mistake rather than a tactical maneuver.1Supreme Court of California. Saint Francis Memorial Hospital v. State Department of Public Health A plaintiff who filed in federal court because of a genuine jurisdictional question looks very different from one who dismissed a case voluntarily and tried to refile later. Courts also expect quick action once the first proceeding ends. Waiting months without explanation after the tolling event is over will sink a claim.

When Equitable Tolling Typically Applies

Equitable tolling is not a general safety net. It shows up in a narrow set of recurring situations, all involving a plaintiff who picked one available legal path before switching to another.

Filing in a Court That Lacks Jurisdiction

The classic example is a plaintiff who timely files a state-law claim in federal court, only to have it dismissed for lack of jurisdiction. The time the federal action was pending can be tolled for refiling in state court, provided the three Addison requirements are met. If the jurisdictional question was genuinely uncertain, courts treat the federal filing as evidence of diligence rather than negligence.5Justia. CACI No. 457 – Statute of Limitations – Equitable Tolling – Other Prior Proceeding

Exhausting Administrative Remedies

Many California claims require an administrative step before a civil lawsuit. FEHA discrimination and harassment claims are the main example. A plaintiff first files with the Civil Rights Department (formerly DFEH) and can only sue after receiving a right-to-sue notice. The one-year deadline to file suit runs from that notice. When the EEOC and the state agency are both investigating the same charge, the FEHA limitations period is tolled while the federal investigation plays out.6California Legislative Information. California Government Code 12965

Workers’ compensation is another recurring context. A worker pursuing a comp claim for a workplace injury may also have a civil personal injury claim against a third party based on the same facts. Time spent on the comp claim can toll the limitations period for the related civil action, because the proceedings share underlying facts and the defendant is on notice of the injury.

Voluntary Dismissals Are a Different Story

Courts draw a hard line between a plaintiff forced out of one forum and a plaintiff who leaves on their own. A California Court of Appeal rejected equitable tolling where a plaintiff voluntarily dismissed a state court case, tried to move to federal court, failed, and then tried to return to state court after the deadline had passed. The court found that a strategic voluntary dismissal was neither reasonable nor in good faith. Forum-shopping is exactly what equitable tolling was never meant to cover.

How the Clock Works When Tolling Applies

Equitable tolling pauses the clock. It does not reset it. Whatever time was left when the first proceeding began is what remains after that proceeding ends. If you had 90 days left on a two-year deadline when you filed your administrative complaint, you have 90 days to file the civil lawsuit once the administrative process concludes. You do not get a fresh two years, and you do not get extra time beyond what was originally remaining.

This math matters. Plaintiffs who wait until the final weeks of a limitations period to start an administrative remedy can find themselves with an extremely tight window once the process ends. Keeping precise records of when the original limitations period started, when the first proceeding was filed, and when it ended is essential for calculating what is left.

Equitable Tolling vs. Equitable Estoppel

These two doctrines sound similar and get confused constantly, but they look at different conduct. Equitable tolling focuses on the plaintiff’s behavior: did the plaintiff act diligently and in good faith while pursuing another remedy? The defendant’s conduct is irrelevant. Equitable estoppel focuses on the defendant’s misconduct and prevents a defendant from using an expired statute of limitations as a shield when the defendant’s own actions caused the plaintiff to miss the deadline.5Justia. CACI No. 457 – Statute of Limitations – Equitable Tolling – Other Prior Proceeding

The California Supreme Court explained the split in Lantzy v. Centex Homes: tolling addresses when the limitations period runs and when it can be suspended, while estoppel applies only after the period has already expired and bars the defendant from raising the deadline as a defense. If your employer told you the complaint was being handled internally and that caused you to miss the filing window, that is an estoppel question. If you filed a timely workers’ comp claim and are now bringing a civil lawsuit on the same injury, that is a tolling question.

Statutes of Repose Are a Hard Stop

Equitable tolling generally cannot extend a statute of repose. A statute of limitations starts when you discover (or should have discovered) your injury. A statute of repose starts from a fixed event regardless of when you learn about your claim, and it sets an absolute outer boundary on liability. California’s ten-year construction defect statute of repose is the common example: no action for a latent deficiency in design or construction can be brought more than ten years after substantial completion, regardless of when the defect is discovered.7California Legislative Information. California Code of Civil Procedure 337.15

The U.S. Supreme Court reinforced the principle in California Public Employees’ Retirement System v. ANZ Securities, Inc., holding that federal securities statutes of repose cannot be tolled by equitable or class-action tolling principles. The reasoning carries over broadly. Repose statutes exist to give defendants a guaranteed end date for potential liability, and equitable exceptions would defeat that purpose. If your claim is governed by a statute of repose rather than a standard limitations period, equitable tolling will almost certainly not save a late filing.
