Key Wyoming Statutes Reference for the Legal System
Wyoming's statutory framework governs civil liability, criminal prosecution, property rights, family matters, and administrative procedure across the state. The Wyoming Statutes, compiled and maintained by the Wyoming Legislature, organize these laws into titles and chapters that courts and agencies apply daily. Understanding which statutes control a given dispute, transaction, or proceeding is foundational to navigating the Wyoming legal system at any level.
Definition and Scope
Wyoming statutes are codified acts passed by the Wyoming Legislature and signed into law by the Governor, organized within the Wyoming Statutes Annotated (Wyoming Legislature, official statutes portal). The code is divided into 99 titles covering subject areas from judicial procedure (Title 1) through public utilities (Title 37) and criminal code (Title 6). Each title contains chapters, articles, and individual numbered sections that carry full legal force.
Statutory law interacts with three other bodies of authority: the Wyoming Constitution, administrative rules promulgated by state agencies under the Wyoming Administrative Procedure Act (Wyo. Stat. § 16-3-101 et seq.), and common law developed through court decisions. Statutory text controls where it addresses a subject directly; where gaps exist, courts apply common law principles.
The scope of Wyoming statutes is bounded by state territorial jurisdiction. Federal statutes — including those enforced through the U.S. District Court for the District of Wyoming — operate concurrently but are not part of the Wyoming code. Tribal codes governing the Eastern Shoshone and Northern Arapaho Nations on the Wind River Reservation operate under separate sovereign authority and are addressed in the context of Wyoming tribal courts and sovereignty.
Scope limitations: This page covers Wyoming state statutes only. Federal regulatory statutes, municipal ordinances, and tribal law are outside its coverage. Interstate compacts ratified by Wyoming have statutory effect but are enforced through the relevant compacting agencies rather than state courts alone.
How It Works
The Wyoming Legislature enacts statutes through a bicameral process involving the House of Representatives and the Senate. Once codified, statutes are applied through a structured interpretive hierarchy:
- Plain meaning rule — Courts first apply the ordinary meaning of statutory text (Wyoming Supreme Court interpretive doctrine, consistent with Parker Land and Cattle Co. v. Wyoming Game and Fish Comm'n, 845 P.2d 1040 (Wyo. 1993)).
- Statutory construction — Where ambiguity exists, courts examine legislative history, chapter structure, and related provisions within the same title.
- Administrative deference — When a statute delegates rule-making to an agency, the agency's implementing regulations carry interpretive weight, subject to judicial review under Wyo. Stat. § 16-3-114.
- Constitutional filter — Any statute conflicting with the Wyoming Constitution or the U.S. Constitution is subject to invalidation. The Wyoming Supreme Court exercises final authority on state constitutional questions.
Practitioners and self-represented litigants accessing the code should reference the Wyoming rules of civil procedure and Wyoming rules of criminal procedure alongside substantive statutes, as procedural rules govern how statutory rights are exercised in court. The Wyoming rules of evidence control admissibility of proof supporting statutory claims.

Common Scenarios
Several title groupings account for the highest volume of litigation and administrative proceedings in Wyoming courts:
Title 6 — Crimes and Offenses
Wyoming's criminal code classifies felonies and misdemeanors with specific penalty ranges. A felony of the first degree carries a maximum imprisonment term of life (Wyo. Stat. § 6-10-101). Sentencing structure is elaborated in Wyoming sentencing guidelines and criminal penalties. Record relief after conviction is addressed separately under Wyoming expungement and record sealing.
Title 1 — Court Procedure and Civil Actions
Title 1 governs limitations periods, venue, pleading, and judgment enforcement. The general Wyoming statute of limitations reference outlines the standard four-year period for contract claims (Wyo. Stat. § 1-3-105) versus the three-year period for personal injury claims (Wyo. Stat. § 1-3-106).
Title 20 — Domestic Relations
Divorce, child custody, child support, and adoption proceedings are governed by Title 20. Child support calculation follows the Wyoming Child Support Guidelines, which courts apply as a rebuttable presumption. This statutory area intersects with Wyoming family law.
Title 27 — Labor and Employment
Wyoming's workers' compensation system operates under Title 27, administered by the Wyoming Department of Workforce Services. Employer coverage requirements and benefit schedules are statutory rather than court-determined. The Wyoming workers' compensation legal framework page addresses this structure in detail.
Title 34 — Property
Real property conveyance, recording requirements, and lien priority rules fall under Title 34. This title intersects with Wyoming property law and Wyoming landlord-tenant legal framework.
Title 35 — Public Health and Environment
Environmental permitting obligations with statutory foundations in Title 35 are enforced by the Wyoming Department of Environmental Quality (DEQ). The broader regulatory context appears in Wyoming environmental law and regulatory system and Wyoming energy and natural resources law.
Decision Boundaries
Determining which statute controls a given situation requires classifying the legal question along three axes:
| Axis | Question | Determining Factor |
|---|---|---|
| Civil vs. Criminal | Is the state seeking punishment or a private party seeking remedy? | The title structure and the identity of the plaintiff/prosecutor |
| State vs. Federal | Does federal preemption or exclusive federal jurisdiction apply? | Supremacy Clause analysis; concurrent jurisdiction rules |
| Substantive vs. Procedural | Does the statute create a right, or does it govern how a right is enforced? | Title 1 procedural rules vs. substantive titles |
Civil versus criminal distinction: A single act may trigger both criminal liability under Title 6 and civil liability under Title 1 or a specialized title. Conviction under Title 6 does not require a separate civil judgment, and a civil verdict operates independently of criminal prosecution outcomes. This distinction is foundational to Wyoming civil law framework and Wyoming criminal law framework.
Agency-administered statutes versus court-administered statutes: Statutes conferring jurisdiction on administrative agencies — such as the Wyoming Department of Revenue (property taxation under Title 39) or the Wyoming Public Service Commission (utilities under Title 37) — route disputes through the administrative process first. Judicial review of agency action then follows under Wyo. Stat. § 16-3-114 rather than through direct civil filing. The Wyoming administrative law and agencies page covers this pathway.
Constitutional rights boundaries: Statutes that burden speech, search, or due process rights encounter constitutional scrutiny. The Wyoming legal system and constitutional rights page addresses how courts calibrate statutory authority against constitutional limits. The Wyoming civil rights enforcement mechanisms page covers statutory remedies available when constitutional protections are violated.
For definitions of terms used across these statutory domains, the Wyoming legal system terminology and definitions page provides a structured glossary. The regulatory context for Wyoming's legal system page identifies the administrative agencies whose enabling statutes shape how titles interact with day-to-day enforcement.
