Dismissal, almost without exception
If a personal injury lawsuit is filed in DC after the applicable statute of limitations has run — the general three-year deadline under D.C. Code § 12-301, the one-year period for an intentional tort, or a missed notice requirement — the court will almost always dismiss the case as time-barred. This happens regardless of how strong the underlying claim actually is or how serious the injury turned out to be.
Courts apply these deadlines strictly
Statutes of limitations exist specifically to create a firm, predictable cutoff, and DC courts generally enforce them that way. Being close to the deadline, or having a sympathetic reason for the delay that doesn't fit a recognized legal exception, isn't on its own a basis for a court to excuse a late filing.
A real, distinctive risk: the malpractice notice window
Because DC's medical malpractice notice must be given at least 90 days before filing, not simply sometime within the three-year deadline, someone who waits too long to start the notice process can genuinely run out of usable time, even while the three-year figure still looks comfortably far off. Treating the notice step as needing to start well before the three-year mark, rather than as a formality that can wait, avoids this specific trap.
A similar risk for District government claims
The same logic applies to the six-month notice requirement for a claim against the District government. Missing that window can bar the claim entirely, independent of how much time remains under the general three-year rule. See our guide to DC's government notice requirement for exactly how that works, including the police-report shortcut.
Negotiations end along with the legal leverage behind them
One of the more painful practical consequences: once the statute of limitations has actually run, an insurance company has no legal obligation to keep negotiating, to make any offer, or to pay anything at all — even if settlement talks were active and seemingly productive right up until the deadline passed.
If there's any doubt at all
Because the consequence of missing a deadline is generally permanent, and because DC's rules genuinely depend on the type of claim and whether notice requirements apply, the only reliable way to know where things actually stand is to confirm the exact date with a licensed DC attorney as early as possible.
