Statute of Limitations for Unjust Enrichment / Restitution in North Dakota
7 min read
Published March 22, 2026 • By DocketMath Team
Overview
North Dakota law recognizes restitution-style claims under the broader umbrella of unjust enrichment and related equitable remedies. When those claims are brought late, the statute of limitations can bar recovery—often turning on a single question: when the limitations clock started.
This guide focuses on North Dakota timelines for claims seeking restitutionary relief (commonly pleaded as unjust enrichment) and how you can sanity-check deadlines using DocketMath’s statute-of-limitations tool. It’s written to help you plan research and document review, not to provide legal advice.
Note: “Unjust enrichment” is often pled alongside other theories. The limitations period can differ depending on how the claim is characterized (equitable restitution, contractual dispute, or a statutory claim). This page focuses on restitution/unjust-enrichment style limitations in North Dakota.
Before you calculate anything, identify:
- The date of the alleged enrichment (e.g., payment, transfer, or benefit received)
- The date the claimant knew or should have known of the basis for the claim (in jurisdictions that apply discovery concepts)
- Whether the claim is tied to fraud, conversion, injury to property, or breach of a written obligation, because those categories may move the timeline
If you’re working from pleadings or demand letters, locate:
- The complaint’s “facts” timeline
- Any allegation about when discovery occurred
- Any mention of tolling (e.g., concealment) or equitable tolling language
Then you can plug the key dates into DocketMath.
Limitation period
In North Dakota, the limitations period depends heavily on the claim type. For restitutionary/unjust-enrichment theories, practitioners typically look to North Dakota’s catch-all civil limitations framework rather than a “specific unjust enrichment statute” (because unjust enrichment is generally an equitable doctrine, not always mapped to a single stand-alone limitations section).
For many restitution-based disputes, the commonly applied approach is:
- A residual limitations period for civil actions not otherwise covered by a more specific statute.
- A possible discovery-based trigger only where North Dakota law provides it for that type of action or where the claim is framed in a way that activates discovery concepts (for example, fraud-related theories).
Because the “how it’s framed” question is often decisive, you should treat the limitations period as a two-step workflow:
Classify the claim
- Is it a restitutionary claim for a benefit wrongfully retained?
- Or is it effectively a contract dispute (even if styled as unjust enrichment)?
- Is there a statutory angle (consumer, securities, wage, etc.)?
Identify the accrual/trigger date
- Some causes accrue on the date of the transaction or injury.
- Others accrue when the plaintiff knew (or should have known) the facts establishing the claim.
- Fraud and concealment frequently change the analysis.
Use DocketMath to test deadlines using the most likely trigger date you have from the record. If you change the trigger date (for instance, “actual knowledge” vs. “should have known”), you’ll see the output shift—an immediate way to evaluate which deadline is controlling.
Key exceptions
North Dakota limitations analysis can shift due to exceptions and tolling concepts. While unjust enrichment itself is equitable, limitations exceptions can still matter because courts apply statutes of limitation to equitable claims when they fit the governing limitations category.
Common “deadline movers” include:
Fraud / concealment-related tolling
- If the complaint alleges that the defendant concealed facts, defendants often argue for a later accrual or tolling period depending on how the cause of action is categorized.
- Conversely, claimants may rely on concealment allegations to argue delayed discovery.
Actions involving specific statutory schemes
- If the restitution claim overlaps with a statutory cause of action (for example, a consumer protection statute), the limitations period may be set by the statute and not by the residual civil limitations provision.
- In those cases, unjust enrichment can’t always be analyzed in isolation.
Contract characterization
- If the real dispute is “payment due under a contract,” some courts may treat restitution theories as an indirect way to collect on a contract obligation.
- The practical implication: the limitations period may align more closely with the contract-based limitations scheme, depending on the pleadings and proof.
Accrual trigger disputes
- Even when the limitations period is the same length, the trigger may be contested:
- Payment date vs. retention date
- Knowledge date vs. when the plaintiff should have discovered the facts
- Continuing enrichment vs. one-time transaction
Warning: Don’t assume the limitations period stays the same after you amend the complaint. Changing the “story” (e.g., adding fraud allegations or reframing the dispute as statutory) can change both accrual and the controlling limitations statute.
A practical workflow for exception spotting:
- Check whether the complaint includes fraud/misrepresentation or concealment
- Look for allegations of when the claimant learned the facts
- Identify whether the defendant’s conduct is one-time or ongoing
- Confirm whether any additional statutory claims were pleaded (even if later dismissed)
Statute citation
North Dakota’s limitations analysis for civil claims not governed by a more specific statute typically starts with the state’s residual limitations provision for actions based on obligations, liabilities, or civil wrongs that are not otherwise enumerated.
North Dakota Century Code (N.D.C.C.) § 28-01-15 is the key starting point for the general civil limitations period for actions not specifically covered elsewhere in Chapter 28-01. In many unjust-enrichment/restitution fact patterns, this residual provision is the anchor for calculating the deadline.
When discovery concepts or tolling are invoked, you also need to review whether other sections in N.D.C.C. Chapter 28-01 (or related chapters) apply based on:
- the nature of the alleged wrong,
- any statutory cause of action,
- and how the claim was pled (including fraud allegations).
Because unjust enrichment is often pleaded in multiple ways, the most accurate citation choice depends on the claims asserted in the pleadings and the proof theory.
Use the calculator
DocketMath’s statute-of-limitations calculator helps you convert the relevant North Dakota limitations period and an accrual date into a concrete “latest filing” date.
What to enter
Use these inputs to mirror what your record shows:
- Jurisdiction: US-ND (North Dakota)
- Claim type: choose the restitution/unjust-enrichment pathway that best matches your pleadings (or the residual civil timeframe if that’s what your research supports)
- Accrual date (start date): the date you believe the cause of action accrued
- Common choices: the date of payment/transfer, the date of retention, or the date of discovery alleged in the record
- Filing date (optional, if your workflow includes it): enter the date you plan to file (or the actual filing date) to see whether the deadline was met
How the output changes
Two changes typically swing the result:
- Accrual date selection
- Moving the accrual date forward by 60 days can shift the “latest filing date” forward by 60 days.
- Claim characterization
- If your claim is treated as falling under a specific category rather than the residual civil period, the limitations length can change. The calculator will reflect the selected pathway.

If you want faster internal review:
- Run two scenarios:
- Scenario A: accrual = transaction/payment date
- Scenario B: accrual = discovery/knowledge date alleged in the complaint
- Compare the outputs and identify which scenario better matches the record.
Pitfall: Calculators are only as good as the dates you choose. If your “accrual date” is off by weeks or months, the output can look decisive even though the real dispute is about when accrual happened.

Start with the primary authority for North Dakota and confirm the effective date before relying on any output. If the rule has been amended, update the inputs and rerun the calculation.
