Wyo. Stat. § 4-10-517 (2026)

qualified spendthrift trust.

     (a) Notwithstanding any law to the contrary, a creditor or
assignee of a settlor of a qualified spendthrift trust, or an
agent of a creditor or settlor, has only those rights with
respect to the qualified trust property as are provided in W.S.
4-10-514 through 4-10-523 and no creditor, assignee or agent may
have any claim or cause of action against the trustee, trust
protector, trust advisor or other fiduciary of the trust, or
against any person involved in the counseling, drafting,
administration, preparation, execution or funding of the trust
unless the creditor, assignee or agent can prove by clear and
convincing evidence that the transfer of property to the trust
was a fraudulent transfer pursuant to the provisions of the
Uniform Fraudulent Transfers Act. In the absence of clear and
convincing proof, the property transferred is not subject to the
claims of the creditor, assignee or agent. Proof by one (1)
creditor, assignee or agent that a transfer of property to a
qualified spendthrift trust was fraudulent or wrongful does not
constitute proof as to any other creditor, assignee or agent and
proof of a fraudulent or wrongful transfer of property as to one
(1) creditor, assignee or agent shall not invalidate any other
qualified transfer of property.

     (b) A creditor or assignee of a settlor of a trust or a
beneficiary of a qualified spendthrift trust shall have no right
to raise a claim for forced heirship or legitime. No creditor,
assignee or agent shall have any claim or cause of action for
forced heirship or legitime against the trustee, trust
protector, trust advisor or other fiduciary of the qualified
spendthrift trust or against any person involved in the
counseling, drafting, administration, preparation, execution or
funding of the trust. Any property transferred to the qualified
spendthrift trust is not subject to the claims of a creditor,
assignee or agent for forced heirship or legitime.
