The Qualified Spendthrift Trust.
Wyoming enacted the Qualified Spendthrift Trust framework in 2007, expanded it in 2013, and refined it again in 2015. Under Wyo. Stat. § 4-10-510(a), a qualifying trust must be irrevocable, contain a spendthrift provision, expressly incorporate Wyoming law for validity, construction, and administration, and stipulate that it is governed by the QST statute. Within those formal requirements lies one of the more considered domestic asset-protection regimes in the United States.
Private Trust Companies.
Under Wyo. Stat. § 4-10-103(a)(xxxv)(B), a private trust company organized in Wyoming may serve as the qualified trustee of a QST so long as it maintains custody or records in the state, prepares fiduciary tax returns, or otherwise materially participates in administration. The firm establishes and administers private trust companies on behalf of clients whose holdings warrant the dedicated structure.
Charging-order exclusivity.
Wyoming's LLC statute has continuously reaffirmed the charging order as the exclusive remedy available to a creditor of a member, including in the single-member context — a provision that survives where competing U.S. jurisdictions have weakened it. The result is a domestic LLC that is, by statute, harder to penetrate than most.
