# Unjust Enrichment Restitution Statute Of Limitations in Oregon

Oregon’s statute of limitations for unjust enrichment restitution claims is governed by Or. Rev. Stat. § 12.110(1), which sets a two-year filing period. This subsection applies to actions for relief not otherwise specifically prescribed, including claims seeking restitution based on unjust enrichment. The two-year period begins to run when the cause of action accrues, generally when the plaintiff discovers or reasonably should have discovered the facts giving rise to the claim. The official statute provides detail on accrual and any applicable exceptions. A worked example below demonstrates how the two-year limitation applies to a typical unjust enrichment scenario. To estimate the filing deadline for a specific set of facts, use the DocketMath calculator.

ORS 12.110(1) expressly embeds a discovery rule for fraud and deceit actions: the limitation commences only from discovery. Under Berry v. Branner, 245 Or 307 (1966), Oregon courts extended this discovery principle to all tort actions under ORS 12.010, so actions do not accrue until the plaintiff knew or reasonably should have known of the injury.

Oregon Supreme Court (Sept. 2025) confirmed Oregon's discovery rule framework, tracing it to Berry v. Branner, 245 Or 307 (1966) and ORS 12.110(1). The Court confirmed the rule means actions accrue when the plaintiff 'obtained knowledge, or reasonably should have obtained knowledge of the tort.' ORS 12.010 supplies the accrual definition that embeds the discovery rule for all tort statutes of limitation in ORS chapter 12.

An action brought under the Oregon Unlawful Trade Practices Act (ORS 646.605–646.652) by a private party must be commenced within one year. The clock runs from the discovery of the unlawful method, act, or practice.

Under Or. Rev. Stat. § 12.110(1), an action for assault, battery, false imprisonment, or any injury to the person or rights of another (not arising on contract and not specifically enumerated) must be commenced within two years. Fraud/deceit actions accrue at discovery. This covers general PI, negligence, premises liability, product liability, slip-and-fall, dog bite, assault/battery, false imprisonment.

Under Or. Rev. Stat. § 12.080(1), an action upon a contract or liability, express or implied (excluding certain enumerated PI actions), must be commenced within six years. Oregon courts treat breach of fiduciary duty as falling within this 'liability, express or implied' clause, yielding a 6-year SOL.

Under Or. Rev. Stat. § 646.638(6), private UTPA actions must be commenced within one year after the discovery of the unlawful method, act or practice. The SOL is tolled while a prosecuting attorney's complaint under § 646.608 is pending, as to private actions based on matters in that complaint.

Under Or. Rev. Stat. § 12.135, actions arising from construction, alteration, or repair of improvements to real property (or supervision/design/planning/surveying/architectural/engineering services therefor) — whether in contract, tort, or otherwise — must be commenced within the applicable SOL otherwise established by law, BUT in no event later than 10 years from the date of substantial completion or abandonment. The 10-year period is a statute of repose; the underlying SOL (typically 2yr PI or

Under ORS § 659A.875(1)(a), a civil action under § 659A.885 alleging an unlawful employment practice must be commenced within 1 year after the occurrence (subject to specific carve-outs in § 243.323, § 659A.030, § 659A.082, § 659A.112, § 659A.370) and to BOLI administrative tolling under § 659A.820.

In Oregon, a quasi-contract unjust enrichment or restitution claim centered on payment, expenses, or services uses the six-year period in Or. Rev. Stat. section 12.080(1) as the analogous limitations reference. Oregon courts frame unjust enrichment as equitable and subject to laches, so accrual and delay remain fact-specific; this receipt does not certify tort-grounded unjust enrichment theories.

An Oregon claim for breach of fiduciary duty is a non-contract injury to the rights of another within ORS 12.110(1) and must be commenced within two years. Under the Oregon Supreme Court's en banc decision in FDIC v. Smith, 328 Or 420, 432 (1999), breach-of-fiduciary-duty actions are governed by the same limitations provision that applies to negligence actions — ORS 12.110(1) — and are subject to the discovery rule, with the cause of action accruing when the plaintiff knew or in the exercise of 

An Oregon civil action arising from domestic-violence conduct — typically pleaded as assault, battery, intentional infliction of emotional distress, or other injury to the person — is subject to the general two-year statute of limitations at ORS 12.110(1). Oregon does not have a separate, claim-type-specific civil statute of limitations for domestic-violence claims. The exception at ORS 12.118 (unlimited period) applies only to claims constituting sexual assault of an adult; non-sexual-assault d

In Oregon, tortious interference with business relations is an intentional tort subject to the two-year statute of limitations under ORS § 12.110(1). The claim does not arise on contract and is not specially enumerated in ORS chapter 12, placing it within the § 12.110(1) catch-all for 'any injury to the person or rights of another, not arising on contract, and not especially enumerated in this chapter.'

In Oregon, a prosecution for any misdemeanor (including Class A misdemeanors) must be commenced within two years after the commission of the crime under ORS § 131.125(8)(b). The accrual date is the date of commission of the offense per ORS § 131.145.

In Oregon, a civil action for common-law fraud or deceit must be commenced within two years of the discovery of the fraud or deceit under ORS § 12.110(1). The statutory discovery rule means the two-year period does not begin until the plaintiff discovers (or reasonably should discover) the fraudulent conduct.

Under ORS 18.180(5), judgment remedies for the child support award portion of an Oregon circuit court judgment expire 35 years after entry of the judgment that first establishes the support obligation. This carve-out overrides the general 10-year civil judgment period under ORS 18.180(3) and ORS 12.070. Modification may be initiated by the state child support agency after three years from the original order or last modification under ORS 25.287, or by any party upon a showing of substantial chan

Under ORS 12.117(1)(b), '[a]n action based on child sexual abuse or conduct allowing, permitting or encouraging child sexual abuse may be commenced at any time.' Oregon has eliminated the statute of limitations for civil claims arising from child sexual abuse. This no-limitation rule applies notwithstanding ORS 12.110, 12.115, and 12.160 (the general tort and personal injury limitation provisions). 'Child sexual abuse' is defined in ORS 12.117(2)(b) to include rape of a child (rape, sodomy, unla

Oregon Supreme Court (Sept. 2025) confirmed Oregon's discovery rule framework, tracing it to Berry v. Branner, 245 Or 307 (1966) and ORS 12.110(1). Confirms discovery rule is embodied in ORS 12.110(1) and applied via ORS 12.010's accrual definition to all ORS chapter 12 tort limitation periods.

ORS 12.160 tolls all civil statutes of limitations for minor plaintiffs (under 18) for the duration of their minority, subject to two hard caps: (a) no more than 5 years total extension, or (b) no more than 1 year after the minor turns 18, whichever occurs first. Medical expense claims by a parent or guardian arising from the same wrongful act are tolled for the same period (§ 12.160(5)).

ORS 12.150 ('Suspension of running of statute by absence or concealment') tolls Oregon statutes of limitations when a defendant is absent from the state. Time of absence is excluded from the limitation period, for both pre-accrual and post-accrual departures.

ORS 12.150 expressly covers concealment within the state as a separate tolling trigger from absence. Both concealment and absence are governed by § 12.150 and the same rule applies: time of concealment is not counted toward the limitations period.

(1) An action against a sheriff or other officer for the escape of a prisoner arrested or imprisoned on civil process; or (2) An action for libel or slander shall be commenced within one year.

An action for any cause not otherwise provided for shall be commenced within 10 years.

(1) In no event shall any action for negligent injury to person or property of another be commenced more than 10 years from the date of the act or omission complained of. (2) Nothing in this section shall be construed to extend any period of limitation otherwise established by law, including but not limited to the limitations established by ORS 12.110.

Suspension for minors and persons who have disabling mental condition.

If, when a cause of action accrues against any person, the person is out of the state and service cannot be made within the state or the person is concealed therein, such action may be commenced within the applicable period of limitation in this chapter after the return of the person into the state, or after the termination of the concealment of the person; and if, after a cause of action has accrued against a person, the person shall depart from and reside out of this state, or if the person is concealed therein, the time of the absence or concealment of the person shall not be deemed or taken as any part of the time limited for the commencement of such action.

ORS 12.150 ('Suspension of running of statute by absence or concealment') tolls Oregon statutes of limitations when a defendant is absent from the state or concealed. Time of absence or concealment is excluded from the limitation period. Applies both to pre-accrual absence (action may be commenced after return within the limitations period) and post-accrual departure (time away is not counted).

The ANO-710 deep research pass (2026-04-29) independently identified ORS 12.150 as the defendant-absence tolling statute, consistent with the 2026-06-29 direct fetch. Both sources confirm § 12.150 (not § 12.180) is the controlling statute for defendant absence in Oregon.

ORS 12.150 expressly covers concealment within the state ('the person is concealed therein') as a separate tolling trigger from absence. Both concealment and absence are governed by the same section and the same rule: the time of concealment is not counted toward the limitations period.

The ANO-710 deep research pass (2026-04-29) identified ORS 12.150 as governing both defendant absence and concealment, consistent with the 2026-06-29 direct fetch. Both sources confirm § 12.150 is the controlling statute.

Subject to subsection (2) of this section, if a person is entitled to bring an action mentioned in ORS 12.010 to 12.050, 12.070 to 12.250 or 12.276, and at the time the cause of action accrues the person is a child who is younger than 18 years of age, the statute of limitation for commencing the action is tolled for so long as the person is younger than 18 years of age.

Oregon Supreme Court (2021) confirmed the tolling and repose framework for minor plaintiffs under ORS chapter 12. The case shows ORS 12.160 as the operative tolling provision for child plaintiffs (referenced via ORS 12.110(4)'s notwithstanding clause that overrides § 12.160 for medical malpractice). Case law confirms § 12.160 is the sole minor-tolling provision in ORS chapter 12.
