Wyoming Postnuptial Agreement Overview
Wyoming recognizes postnuptial agreements under the Uniform Premarital Agreement Act (Wyoming Statutes Section 20-2-301 through 20-2-310) as extended to marital agreements, and under general contract law principles. Wyoming courts apply the fiduciary duty standard to agreements between married spouses.
Wyoming is an equitable distribution state under Wyoming Statutes Section 20-2-114, where marital property is divided equitably. Wyoming's economy, centered on energy, ranching, and tourism, creates unique property types that postnuptial agreements frequently address.
Wyoming courts apply the fiduciary duty standard to postnuptial agreements. Both spouses should have independent counsel and provide complete financial disclosure. Wyoming's significant ranch land, mineral rights, and energy industry assets require specialized attention in postnuptial agreements.
