Statute of Limitations for Unjust Enrichment / Restitution in District of Columbia
6 min read
Published March 22, 2026 • By DocketMath Team
Overview
In the District of Columbia, claims labeled “unjust enrichment” or “restitution” are usually treated as civil actions subject to a general statute of limitations when no more specific limitation period applies. DocketMath’s statute-of-limitations calculator uses the District of Columbia’s default SOL period for these kinds of claims, so the key practical question becomes:
- What date should you treat as the start of the limitations clock?
- Does the claim depend on any special accrual rule or exception?
Note: This page describes the general/default approach. The District of Columbia materials provided here did not identify a claim-type-specific sub-rule for unjust enrichment or restitution, so the general rule governs.
If you’re building a timeline (for example, for a demand letter, case assessment, or internal risk review), use the general SOL rule first—then check whether any exception or tolling concept might apply to your facts.
Limitation period
General SOL period: 3 years
For civil actions covered by the general limitation provision, the District of Columbia sets a 3-year limitations period.
- Default period: 3 years
- General statute: **D.C. Code § 23–113(a)(1)
When the clock starts (practical framing)
Most statute-of-limitations analysis turns on accrual—the date when the claim “arises” or when the plaintiff could sue. In day-to-day case triage, people often summarize this as:
- Start date = when the injury occurred and the plaintiff had a basis to bring the claim.
Because unjust enrichment and restitution can be argued in different ways (for example, focusing on benefit conferred, receipt of value, or discovery of relevant facts), different accrual theories can move the start date earlier or later. DocketMath’s calculator focuses on the inputs you provide so you can test those timelines systematically.
How to use the “start date” effectively
To make the result actionable, define your inputs consistently. Common approaches include:
- Transaction/receipt date: date the defendant received the benefit
- Loss/injury date: date the plaintiff’s loss is complete
- Demand/knowledge date: date the plaintiff discovered key facts (if you’re applying a discovery/accrual concept)
Even if you ultimately choose one theory, running alternatives can reveal how sensitive the SOL outcome is to the accrual date selection.
Output: what you get from the calculator
DocketMath’s statute-of-limitations calculator typically returns:
- The last day to file under the selected limitations period
- A clear view of the time window (e.g., “file by YYYY-MM-DD”)
If your start date moves by 30, 90, or 365 days, the end date correspondingly shifts—so you can quickly evaluate whether a potential filing date is within the 3-year window.
Warning: Don’t rely on the end date alone. If a tolling argument exists (for example, statutory tolling), the filing deadline can extend beyond what the simple SOL calculation would show.
Key exceptions
No claim-type-specific sub-rule was found in the materials you provided for unjust enrichment or restitution in the District of Columbia. That means the analysis starts with the general 3-year rule.
That said, exceptions and adjustments can still matter. Here are the categories you should check before treating the 3-year deadline as final:
1) Tolling (pauses or extends the limitations period)
Tolling concepts may extend the SOL beyond the unadjusted “3 years from accrual” calculation. Tolling can arise from different legal mechanisms (some are statutory, some are court-created doctrines), and the availability depends heavily on the facts.
Practical checklist:
- Was the plaintiff legally prevented from suing?
- Did the defendant engage in conduct that affected the plaintiff’s ability to file?
- Are there statutory tolling provisions that match the scenario?
2) Accrual disputes (different “start dates”)
Even without a special exception, unjust enrichment/restitution claims can trigger accrual disputes, because the “arises” date may differ depending on how you frame:
- When the benefit was received
- When the plaintiff’s loss became fixed
- When the plaintiff knew (or should have known) relevant facts
Because DocketMath allows you to test different start-date inputs, you can model accrual theories without recalculating manually.
3) Procedural timing choices
Sometimes the “deadline” can turn on procedural events—like when a case is actually filed or whether a prior filing affects the limitations analysis. Those are fact- and procedure-dependent, and DocketMath’s calculator is best used for the limitations arithmetic, not the full litigation procedural strategy.
- Use the calculator to establish a baseline deadline
- Then align that baseline with the filing mechanics you’re actually using
Statute citation
The District of Columbia general statute of limitations for covered civil actions is:
- D.C. Code § 23–113(a)(1) — 3 years

Use the calculator
DocketMath’s statute-of-limitations tool (CTA) helps you compute the deadline using the District of Columbia’s general 3-year rule.
- Primary CTA: /tools/statute-of-limitations
Inputs to consider (and how they change the output)
Use these inputs to get a realistic “file by” date:
- Jurisdiction: District of Columbia (US-DC)
- Claim type: (select the option that routes to the general rule, since no claim-type-specific unjust enrichment/restitution sub-rule was identified here)
- Accrual/start date: the date you believe the claim arose
- Filing date (optional): if you want the tool to evaluate timeliness
Example workflow
- Step 1: Pick a start date (e.g., the date the defendant received the benefit)
- Step 2: Run DocketMath to get the “last day to file”
- Step 3: Re-run using an alternative start date (e.g., knowledge/discovery date) to see how much the deadline shifts
This “what if” approach is useful because SOL outcomes often hinge on a small difference in accrual assumptions.
Interpreting results responsibly
If DocketMath outputs a deadline that is already past, that doesn’t automatically end the discussion—exceptions like tolling or alternate accrual theories may still be available. However, the calculator’s output is the best first-pass deadline for managing schedules, documentation, and internal decision-making.
