When investors think about a securities arbitration or lawsuit, they often focus on what happened, how much was lost, and whether the conduct was wrongful. But many claims run into trouble much earlier than that. In practice, timing issues can end a case, narrow it, or force it into a different forum before anyone fully reaches the underlying facts.
That is especially true in FINRA arbitration, where the six-year eligibility rule under FINRA Rule 12206 can collide with separate state-law statutes of limitation, contractual language, court filings, and procedural deadlines. FINRA’s own filing guidance warns that investors may lose rights if they do not act promptly, and the SEC’s investor education materials make the same point: the six-year FINRA timing rule and statutes of limitation are not the same thing. FINRA’s FAQ and Investor.gov’s arbitration bulletin both explain that a claim may be filed within six years under FINRA rules while still facing a shorter limitations defense.
If you are trying to sort out this timing maze, it may also help to read our broader overview of how eligibility rules and filing windows can interact. In this post, you’ll learn the seven most common time-limit mistakes that can knock a claim out before the merits are heard, and why early review by counsel often changes the path of a case.

This is probably the most common mistake.
Under FINRA Rule 12206(a), a customer claim is generally not eligible for submission to arbitration if six years have elapsed from the occurrence or event giving rise to the claim. That sounds simple, and many investors understandably assume it is the master deadline for the entire dispute.
It is not.
FINRA’s own Filing a Claim FAQ says that statutes of limitation may be shorter than six years, and a respondent may raise those shorter deadlines as a defense. The SEC’s Investor Bulletin on broker-dealer/customer arbitration says the same thing. In other words, filing within six years may still leave part or all of the case vulnerable.
Here’s what this often means in practical terms: a claim can be eligible for FINRA arbitration but still face dismissal, limitation, or reduced recoverability because the governing statute of limitations expired earlier under applicable state or federal law. FINRA reinforced this distinction in Regulatory Notice 26-06, explaining that the eligibility rule is separate from state and federal time limits.
That is one reason investors often benefit from a timeline analysis that goes beyond “Is it under six years?” A lawyer may look at purchase dates, account statements, communications, discovery dates, and later alleged misconduct to determine whether different theories accrued at different times.
Another major timing error is assuming the clock starts on the date an investor realized the loss or the date an account balance visibly collapsed.
FINRA Rule 12206 uses the phrase “occurrence or event giving rise to the claim.” That wording matters. The fight is often not just about whether six years passed, but which event actually started the clock. FINRA’s rule text places that eligibility question in front of the arbitration panel, and Regulatory Notice 26-06 notes that arbitrators are trained to examine whether there was a continuing occurrence or event, rather than automatically locking onto the earliest historical date.
That can cut in either direction.
For some claims, respondents argue the relevant event was the original purchase. For others, claimants argue later misconduct matters too, such as ongoing misrepresentations, unsuitable hold recommendations, repeated account churning, or later concealment. FINRA’s discussion of arbitrator training in Regulatory Notice 26-06 specifically references scenarios where an investment was purchased long ago but the alleged fraud continued into a later period.
This is where timing issues become highly fact-specific. A person might think, “The investment was bought more than six years ago, so the case is over,” when the actual timeline may be more complicated. The reverse can also happen: someone focuses on the most recent damage and overlooks that the actionable event may have occurred much earlier.
A careful chronology can change how a claim is framed, which causes of action remain viable, and whether some damages periods stay in play.
