Defense attorneys don't build the SOL record in plaintiff depositions because they're focused on fraud elements. But the discovery-date question -- what did the plaintiff know and when -- needs to be locked in before the plaintiff has drafted their SOL declaration. Shows the specific deposition agenda for locking in the discovery-date facts.

The SOL Deposition: Building the Discovery-Date Record Before the Defendant Knows You Need It

You are defending a fraud case, the complaint was filed more than three years after the events at issue, and the plaintiff is claiming the limitations period was tolled by late discovery. The statute of limitations is now your strongest defense — but only if the discovery date is locked in by deposition testimony before the plaintiff's counsel understands what you are building.

The Deposition

What the Law Requires

California Code of Civil Procedure section 338(d) provides a three-year limitations period for fraud claims, running from the date the plaintiff "discovered, or through the use of reasonable diligence should have discovered," the facts constituting the fraud. The critical word is "should." Constructive discovery — when the plaintiff had reason to suspect fraud and failed to investigate — starts the clock even if the plaintiff never actually connected the dots. Fox v. Ethicon Endo-Surgery, Inc. (2005) 35 Cal.4th 797, 808.

When the claim appears time-barred on its face, the burden shifts to the plaintiff to prove the discovery date. That burden is yours to press. Before deposing the plaintiff, calculate the limitations period under every scenario: (a) the date the plaintiff identifies as discovery; (b) the earliest date reflected in documents; (c) the latest date on which the plaintiff could arguably have discovered with reasonable diligence. Know where you stand under each scenario.

One variable that has changed the calculus in recent cases: COVID Emergency Rule 9 tolled limitations periods exceeding 180 days for 178 days (April 6, 2020 through October 1, 2020). In Polone v. Shawmut (Beverly Hills Dept 205, Case No. 22SMCV01940), COVID tolling was the margin — the plaintiff's May 2019 discovery date, more than three years before the October 2022 complaint, was saved only by that 178-day toll. Do not skip this calculation.

What the Corpus Shows

In Polone v. Shawmut, the discovery date question was the outcome question. The plaintiff discovered in May 2019 that the agent had not actually sold his prior company — the central misrepresentation. The complaint was filed in October 2022. The three-year window, without tolling, would have expired in May 2022. COVID Rule 9 was the difference. The court's analysis turned entirely on which date controlled and whether tolling applied.

That ruling illustrates the deposition's real function on the SOL issue. The plaintiff's testimony about when he first had reason to suspect something was wrong — not when he was certain — is what the court uses. If the plaintiff testifies to an early red flag and then explains it away, that explanation must survive scrutiny. The deposition is where you pin the earliest possible suspicion date into the record, before the plaintiff has had time to understand why the specific date matters.

What Counsel Does

If you are deposing the plaintiff on the discovery date:

Start with the specific representation at issue: "When did you first learn that [representation] was not accurate?"
Then move to suspicion, which comes earlier: "When did you first suspect that [representation] might not be true?" Suspicion, not certainty, is the legal trigger under section 338(d).
Ask about any inquiries the plaintiff made: "Did you ever ask [company or agent] to confirm whether [representation] was still accurate? When? What were you told?" A reassuring response to an inquiry may toll the period further — fraudulent concealment — but it also locks in the date the plaintiff was already asking questions.
Look for earlier red flags: "Were there any events before [the date the plaintiff just identified] that caused you to question whether [representation] was accurate?" Let the witness answer before moving on. Prior red flags are your best evidence of an earlier constructive discovery date.
Ask about investigation: "Did you take any steps to investigate [representation] before filing suit? When did those steps begin?"
Ask about attorney consultation: "When did you first consult an attorney about potential claims related to this matter?" Attorney consultation is strong evidence of constructive knowledge — the plaintiff was worried enough to get a lawyer.

If you are defending the plaintiff's deposition on the discovery date:

Prepare the client to draw a clean line between noticing problems and suspecting fraud. Mere notice of non-performance — "the project was behind" or "the numbers were off" — is not constructive discovery of fraud. The client must be able to articulate when and why suspicion of intentional misconduct crystallized, not just when things started going wrong.
Identify every inquiry the plaintiff made during the period before suit. If the plaintiff asked questions and received explanations, those responses may constitute fraudulent concealment and toll the period further. Map those exchanges before the deposition.
Calculate the limitations period under at least three scenarios before sitting down: (a) the discovery date the plaintiff identifies; (b) the earliest date reflected in the documents; (c) the latest arguable discovery date under a reasonable diligence standard. Know where the client is under each one before the first question is asked. A witness who cannot answer "and when was that?" without contradicting a prior answer has handed opposing counsel the timeline argument.
