In Wyoming, a mortgage of real estate containing a power of sale may be foreclosed by advertisement within ten (10) years after the maturing of such mortgage or the debt secured thereby (or after the recording thereof, for mortgages without a clearly stated maturity date). Wyoming is a non-judicial foreclosure state; the dominant foreclosure method is by advertisement and sale under W.S. §§ 34-4-101 through 34-4-113. The 10-year period under § 34-4-102(a) is also consistent with the general 10-y

A Wyoming civil action for unjust enrichment, restitution, or quantum meruit is subject to the eight-year statute of limitations at W.S. § 1-3-105(a)(ii)(A) — the lane for 'an action upon a contract not in writing, either express or implied.' Wyoming courts treat unjust enrichment as an equitable remedy that 'implies a contract,' making it a quasi-contract or contract implied in law governed by the unwritten-contract limitations period. Wyoming does not have a separate, claim-type-specific civil

A Wyoming civil action for breach of fiduciary duty sounding in tort is subject to the four-year statute of limitations at W.S. § 1-3-105(a)(iv)(C) — the catchall lane for 'an injury to the rights of the plaintiff, not arising on contract and not herein enumerated.' Wyoming does not have a separate, claim-type-specific civil statute of limitations for breach-of-fiduciary-duty claims. Where a breach-of-fiduciary-duty claim sounds in contract rather than tort, a different period (W.S. § 1-3-105(a)

Wyoming has no criminal statute of limitations for any offense, including misdemeanors. The only limitation statute, Wyo. Stat. § 1-3-102 (Title 1, Chapter 3), expressly applies to 'Civil actions' only. Title 7 (Criminal Procedure) contains 23 chapters with no limitations chapter. Wyoming does not classify misdemeanors by letter grade (A/B/C); under Wyo. Stat. § 6-10-101, all crimes not punishable by death or more than one year imprisonment are 'misdemeanors.' A prosecution for a Wyoming misdeme

Wyoming § 1-3-114 tolls the limitations period for minors and persons under legal disability (excluding professional/health-care services claims) until 3 years after the disability is removed or the general period expires, whichever is greater.

Wyoming § 1-3-116 tolls the limitations period both when the defendant is out of state or has absconded or concealed himself at accrual (period does not begin to run), and excludes time of post-accrual absence or concealment from the running period. A single statute covers all three triggers: out-of-state, absconding, and concealment.

Wyoming has a claim-specific (not universal) discovery rule. § 1-3-106 delays accrual for fraud and wrongful taking until discovery. § 1-3-107 provides a claim-specific discovery extension for professional/health-care services malpractice. Both channels (LDH 2026-04-18 and prior PDF extraction) confirm § 1-3-106 text identically.

Within ten (10) years, an action upon a specialty or any contract, agreement or promise in writing; Within eight (8) years, an action: (A) Upon a contract not in writing, either express or implied; or (B) Upon a liability created by statute other than a forfeiture or penalty.

Within four (4) years, an action for: (A) Trespass upon real property; (B) The recovery of personal property or for taking, detaining or injuring personal property;

A cause of action arising from an act, error or omission in the rendering of licensed or certified professional or health care services shall be brought within the greater of the following times: (i) Within two (2) years of the date of the alleged act, error or omission, except that a cause of action may be instituted not more than two (2) years after discovery of the alleged act, error or omission, if the claimant can establish that the alleged act, error or omission was not reasonably discoverable within a two (2) year period or the claimant failed to discover the alleged act, error or omission within the two (2) year period despite the exercise of due diligence.

Prior PDF extraction omitted the professional-services exclusion. LDH US/WY-Legislation (2026-04-18) confirms current text includes: 'except for an action arising from error or omission in the rendering of licensed or certified professional or health care services'. This aligns with § 1-3-107(b): 'This section applies to all persons regardless of minority or other legal disability.'

If a person entitled to bring any action except for an action arising from error or omission in the rendering of licensed or certified professional or health care services or for a penalty or forfeiture, is, at the time the cause of action accrues, a minor or subject to any other legal disability, the person may bring the action within three (3) years after the disability is removed or within any other statutory period of limitation, whichever is greater.

Prior PDF extraction omitted the disjunctive 'or' before 'has absconded'. LDH US/WY-Legislation (2026-04-18) confirms: 'when he is out of the state, or has absconded or concealed himself'.

If a cause of action accrues against a person when he is out of the state, or has absconded or concealed himself, the period limited for the commencement of the action does not begin to run until he comes into the state or while he is so absconded or concealed. If after the cause of action accrues he departs from the state or absconds or conceals himself, the time of his absence or concealment is not computed as a part of the period within which the action shall be brought.

No action shall be brought under this act against a governmental entity unless the claim upon which the action is based is presented to the entity as an itemized statement in writing within two (2) years of the date of the alleged act, error or omission, except that a cause of action may be instituted not more than two (2) years after discovery of the alleged act, error or omission, if the claimant can establish that the alleged act, error or omission was not reasonably discoverable within a two (2) year period or the claimant failed to discover the alleged act, error or omission within the two (2) year period despite the exercise of due diligence.

Except as otherwise provided, actions against a governmental entity or a public employee acting within the scope of his duties for torts occurring after June 30, 1979 which are subject to this act shall be forever barred unless commenced within one (1) year after the date the claim is filed pursuant to W.S. 1-39-113.
