Statute of Limitations for Unjust Enrichment / Restitution in Ohio

Overview
Run this scenario in DocketMath using the Statute Of Limitations calculator.
Ohio generally uses a 6-month limitations period for unjust-enrichment and restitution-style claims when the claim is pursued under the general limitations framework. In this jurisdiction, Ohio Rev. Code § 2901.13 provides the default rule for an “action for civil liability” that is not governed by a longer, claim-type-specific statute.
In practice, the key SOL question for restitutionary theories is usually not the label “unjust enrichment,” but rather which limitations bucket applies based on the legal theory and the underlying facts (for example, whether a different, longer statute controls due to the specific claim type). If your situation does not fall within a longer, more specific category, Ohio’s general/default rule is the baseline starting point.
Note: This page describes the general/default period. The jurisdiction data you provided indicates no claim-type-specific sub-rule was found for unjust enrichment/restition. Accordingly, this page applies the general rule in Ohio Rev. Code § 2901.13 rather than a longer specialized time bar.
Limitation period
General SOL period: 0.5 years (6 months) under Ohio Rev. Code § 2901.13 (general/default).
To make the 6-month rule usable, think in terms of two dates:
- Start (accrual) date (input): the date the claim “accrues”—often tied to when the wrongful conduct occurred or when the plaintiff could reasonably bring the claim (sometimes framed around discovery, depending on the facts).
- Filing deadline (output): the last day to file suit, calculated by adding 6 months to the accrual/start date, subject to tolling/accrual exceptions that may apply based on the facts.
Because SOL issues can be sensitive to exact dates and triggering events, DocketMath’s statute-of-limitations tool uses date math: you provide the accrual/start date(s), and the tool computes a corresponding deadline using the general/default 6-month rule.
Common filing-deadline workflow (practical, not legal advice)
- Identify the event date(s) you believe trigger accrual (e.g., payment date, receipt of benefits, or when the basis for the claim was discovered).
- Select the accrual/start date you want to test in DocketMath.
- Run the calculator using the general/default rule (since no claim-type-specific unjust-enrichment/restition sub-rule was identified in your data).
- If there are multiple plausible accrual dates, compare outputs (e.g., “payment date” vs. “discovery date”) to see which deadline is controlling for your risk assessment.
Illustrative timeline example
If you enter an accrual/start date of January 10, 2026, the general/default calculation will produce a filing deadline about 6 months later (approximately July 10, 2026, subject to the tool’s exact date-handling conventions).
Key exceptions
A short general limitations period means you may need to focus on (1) when accrual occurred and/or (2) whether the clock was affected. In SOL work, outcomes generally shift through one of the following mechanisms:
- Accrual change: the clock starts later because the claim is not considered “accrued” until a later date.
- Tolling: the clock pauses (or is suspended) during specific circumstances, then resumes afterward.
1) Tolling or accrual theories determine whether the baseline changes
Because this page is limited to the general/default period for unjust enrichment/restitution-style claims, treat exceptions as a “second step” after you compute the baseline deadline. If a recognized doctrine applies, it will typically be because the situation affects accrual or tolls the SOL under Ohio law, not simply because unjust enrichment is described as equitable.
2) “Equitable” framing does not automatically extend the deadline
Even though unjust enrichment and restitution are often discussed in equitable terms, equitable arguments usually do not automatically override statutory time limits. Courts still apply the relevant limitations framework. Under the general/default rule described here, the Ohio Rev. Code § 2901.13 period can still control unless a recognized accrual/tolling/exception mechanism applies.
3) Filing timeliness can depend on procedure, not just the date math
Even if you compute a deadline correctly, timeliness in litigation can also involve procedural mechanics under the applicable civil rules (for example, how a case is initiated and how service requirements are handled). As a practical matter, aim to satisfy the filing deadline first, then ensure compliance with the governing procedural steps.

Statute citation
Ohio Rev. Code § 2901.13 provides the general/default 0.5-year (6-month) limitations period used here for unjust enrichment/restition-style claims when no longer, claim-specific statute applies.
Quick reference table
| Topic | Ohio default for this use case |
|---|---|
| General SOL period | 0.5 years (6 months) |
| Governing statute | Ohio Rev. Code § 2901.13 |
| Claim-specific sub-rule | Not identified in the provided jurisdiction data (so this page uses the general/default rule) |
| Use | Compute deadline from your chosen accrual/start date; then evaluate whether accrual/tolling exceptions could apply |

What to enter in DocketMath (statute-of-limitations)
- Accrual/start date (required): the date you believe the claim accrued (the trigger for the 6-month clock).
- Jurisdiction: select Ohio (US-OH).
- Rule selection: choose the general/default limitations period (0.5 years) tied to Ohio Rev. Code § 2901.13.
What DocketMath’s output represents
DocketMath will compute a filing deadline by adding 6 months to the accrual/start date you selected. If you test multiple accrual dates:
- a later accrual date → a later deadline
- an earlier accrual date → an earlier deadline
The practical impact can be large because a 6-month period is relatively short.
Practical strategy for tight deadlines (input “matrix”)
Because the baseline is short, consider running a few scenarios, where your facts support the accrual framing:
- Scenario A: accrual = “date of payment/benefit received”
- Scenario B: accrual = “date of discovery of the basis”
- Scenario C: accrual = “date of demand/denial” (only if your facts support that accrual theory)
Then compare results and focus on the most defensible accrual framing for your analysis.
