A PAGA case begins with one document.
An LWDA notice is the first thing you will ever see in a PAGA matter — and the moment it arrives, deadlines begin to run. Here is the document, part by part, and what each part means for you.
The 2024 amendments govern a civil action brought on or after June 19, 2024 — unless the LWDA notice was filed before that date, in which case prior law governs (Lab. Code § 2699(v)).The notice procedure lives in Lab. Code § 2699.3, and the standing rule in § 2699(c)(1); both now carry an AB 1170 (eff. Jan. 1, 2026) stamp. AB 1170 was the Legislature’s annual code-maintenance bill and changed nothing of substance. The substantive regime is the 2024 reform — AB 2288 (Stats. 2024, Ch. 44) and SB 92 (Stats. 2024, Ch. 45), signed July 1, 2024.
The notice is the door to the courthouse.#
No notice, no lawsuit. Before a worker can sue under PAGA, the law requires a pre-suit step: the worker must give written notice to the State and to the employer, naming what was broken and why. Completing that step — and waiting out the State’s window — is what the law calls ExhaustionThe requirement to complete the pre-suit steps — file the LWDA notice, pay the fee, and let the State's window pass — before a PAGA lawsuit may be filed; no notice, no suit.Lab. Code § 2699.3(a), and it is a hard precondition to suit, not a formality a court will overlook.
The aggrieved employee or representative shall give written notice by online filing with the Labor and Workforce Development Agency and by certified mail to the employer of the specific provisions of this code alleged to have been violated, including the facts and theories to support the alleged violation.
Before anyone can sue, the worker must file a notice with the State online and mail it to the employer — naming which laws were broken and the facts and theories behind each one. No notice, no lawsuit.
Two things in that single sentence do the heavy lifting. The notice can be given only by an Aggrieved employeeA worker who was employed by the alleged violator and personally suffered each of the violations they allege — the standing rule for a PAGA plaintiff under the 2024 reform. (One narrow exception: in an action filed by a qualifying nonprofit legal aid organization, § 2699(c)(2) keeps the looser pre-reform standard — one or more of the alleged violations.)Lab. Code § 2699(c)(1)–(2) — a worker the employer actually employed, who personally suffered the violations alleged — or that employee’s representative. And it must travel to the LWDAThe Labor and Workforce Development Agency — the state agency that receives the pre-suit notice, may choose to investigate, and collects 65% of any penalties recovered.Lab. Code § 2699(m) by online filing and to the employer by certified mail. Both channels are mandatory; neither substitutes for the other.
What a notice actually says.#
The easiest way to understand a notice is to read one. Below is a synthesized notice — every name, date, and figure is invented for teaching. Select any part of the document to see what it is, why it matters, and the law it rests on.
Illustrative only — a synthesized PAGA notice. The parties, dates, and figures are invented for teaching; this is not a real notice and not a template to file.
Caption — the addressed-to line
Every PAGA notice opens by announcing what it is and where it is going. The two addressees on the caption are not interchangeable: the notice is filed online with the State's Labor and Workforce Development Agency and, separately, mailed to the employer by certified mail. Both are required. The case number is assigned by the LWDA's online system when the notice is filed; it is how the State, the employer, and any later court track the matter.
Lab. Code § 2699.3(a)(1)(A)
The aggrieved employee or representative shall give written notice by online filing with the Labor and Workforce Development Agency and by certified mail to the employer of the specific provisions of this code alleged to have been violated, including the facts and theories to support the alleged violation.
Before anyone can sue, the worker must file a notice with the State online and mail it to the employer — naming which laws were broken and the facts and theories behind each one. No notice, no lawsuit.
Selected part: Caption — the addressed-to line.
What a sufficient notice must contain is governed by the statute and the courts construing it. This explainer describes the document's anatomy; it is educational, not legal advice.
One date starts the clock.#
Of every part of the notice, exactly one starts the State’s clock: the postmark date. Everything downstream — the State’s window, the employer’s deadlines, the earliest day a suit may be filed — is calendared from that single date, which is why the proof of mailing matters as much as the contents above it.
The agency shall notify the employer and the aggrieved employee … that it does not intend to investigate the alleged violation within 60 calendar days of the postmark date of the notice … Upon receipt of that notice or if no notice is provided within 65 calendar days of the postmark date of the notice …, the aggrieved employee may commence a civil action …
The State has 60 days to say whether it will step in. If it declines — or, as is almost always the case, simply says nothing within 65 days — the worker is free to file in court.
From the postmark, the agency has 60 days to say it does not intend to investigate — and through day 65 to say it does. If it declines — or, as is almost always the case, says nothing within 65 days — the aggrieved employee may file in court. The notice also carries a § 2699.3(a)(1)(B) filing fee:
A notice filed with the Labor and Workforce Development Agency … and any employer response to that notice shall be accompanied by a filing fee of seventy-five dollars ($75).
Filing the notice costs $75 — and the employer's written response costs $75 too. Both fees can be waived for those who genuinely can't afford them.
The same $75 attaches to the employer’s written response, and both fees can be waived for a filer who genuinely cannot afford them. The fee is small; the date is not. The window the postmark opens is also what the pre-suit TollingA pause on the clock for filing suit; the pre-suit notice period suspends PAGA's limitations deadline so the time spent waiting on the State does not run against the employee.Lab. Code § 2699.3(e) rule protects, so the time spent waiting on the State does not run against the employee’s deadline to sue.
Facts and theories is a pleading standard, not a formality.#
The statute does not let a notice merely recite section numbers. It must include the facts and theories supporting each alleged violation — and that requirement is the first thing many defenses test. A notice that lists provisions without facts is vulnerable; whether a given notice clears the bar is, often, the opening move in the case.
The aggrieved employee or representative shall give written notice by online filing with the Labor and Workforce Development Agency and by certified mail to the employer of the specific provisions of this code alleged to have been violated, including the facts and theories to support the alleged violation.
Before anyone can sue, the worker must file a notice with the State online and mail it to the employer — naming which laws were broken and the facts and theories behind each one. No notice, no lawsuit.
Here is the candid part: how much factual detail makes a notice “sufficient” is still being worked out by the courts.The 2024 amendments rewrote and renumbered the notice machinery, and no published California decision has yet construed the sufficiency standard under the amended text. The bar a notice must clear is being settled in practice and may be sharpened by LWDA rulemaking before the courts reach it — there is no controlling decision as of July 13, 2026. What is settled is the shape of the inquiry: enough fact to put the employer and the State on notice of what is alleged and why. There is a second filter that operates alongside it — most provisions a notice lists must also appear on the § 2699.5 covered list for the notice-and-cure procedure to attach at all.
What to do now.#
A notice is a beginning, not a verdict. Where you stand depends on who you are.
- Calendar the clock immediately. From the postmark date, the State has 60 days to say it does not intend to investigate (an intent notice may issue through day 65); if it stays silent for 65 days, the employee may sue.
- Plan the $75 response fee and do not botch service. Your written response carries its own $75 fee (waivable), and the two service channels — online LWDA filing and certified mail — are both the statute's.
- Assess the notice's contents and your cure options before responding — what the facts and theories actually allege frames both your defenses and anything you might fix.
A PAGA case starts with a document, and the document starts a clock — read the facts, find the postmark.
