Does Wyoming Recognize Common-Law Partnerships?

No. Wyoming does not recognize common-law partnerships or marriages. Wyoming abolished common-law marriage recognition effective January 1, 1959. All business partnerships and marital relationships require formal registration or licensing to have legal standing. Operating informally with another person provides zero statutory protection and exposes both parties to unlimited personal liability.

Wyoming's Formal Registration Requirement

Wyoming law requires explicit filing with the Secretary of State to establish any recognized business entity. Under Wyo. Stat. §§ 17-29-201 through 17-29-205, a Limited Liability Company must file Articles of Organization. A general or limited partnership must register formally. A corporation must file Articles of Incorporation. No common-law or informal arrangement substitutes for these filings.

Without formal registration, Wyoming courts will not recognize you as partners. Creditors can pursue both parties' personal assets. Tax liability falls on individuals, not a protected entity. Disputes between informal partners have no statutory framework for resolution.

Formal Business Entity Options

Limited Liability Company (LLC) File Articles of Organization with the Wyoming Secretary of State. Filing fee: $100. Processing time: up to 15 business days (paper) or faster online through WyoBiz. Wyoming LLCs require a registered agent and office address. Minimum one member required. Wyoming provides strong charging order protection under Wyo. Stat. § 17-29-503, shielding member assets from creditors—a major advantage over informal arrangements.

General or Limited Partnership Register with the Secretary of State. General partners assume personal liability; limited partners enjoy protection if uninvolved in management. Formal registration is mandatory.

Corporation File Articles of Incorporation for C or S corporation status. Provides liability protection with greater regulatory compliance than LLCs.

What You Must Do

Stop operating informally. Common-law partnership claims will fail in Wyoming courts.
File formation documents. Choose LLC, partnership, or corporation and submit required articles to the Wyoming Secretary of State.
Execute a written agreement. Create an operating agreement (LLC) or partnership agreement defining roles, profit sharing, and dispute resolution.
Obtain an EIN. Apply to the IRS for an Employer Identification Number.
Consult a Wyoming attorney. An attorney can recommend the structure that best protects your personal assets under Wyoming law.

Wyoming's LLC framework is popular because it combines liability protection with flexible management and favorable creditor protections.
