Wyoming: Certification of Trust Requirements
The short answer
Wyoming lets a trustee furnish a nonbeneficiary either a certification or an affidavit of trust instead of the trust instrument. It must contain seven substantive information groups plus a statement that no change makes its representations incorrect; the TIN is expressly optional, and any trustee must sign or otherwise authenticate the document. Dispositive terms may stay private, limited trustee-and-power excerpts may be demanded, and protected reliance and good-faith enforcement apply; a court-found bad-faith demand for the full instrument can produce damages.

Requirements one by one
Wyoming requires seven substantive information groups
W.S. § 4-10-1014(a) lets a trustee furnish either a certification or an affidavit
instead of the trust instrument to a person other than a beneficiary. The document
must state the trust's existence and execution date, settlor identity, the current
trustee's identity and address, pertinent trustee powers, revocability and any
revocation-power holder, cotrustee authentication and exercise authority, and the
manner of taking title to trust property.
The list also labels the trust's TIN “optional.” Subsection (d) removes any doubt by
stating that the certification or affidavit need not contain the TIN. Subsection (c)
separately requires a statement that no revocation, modification, or amendment makes
the document's representations incorrect.
Authentication is mandatory, but any trustee may provide it
Section 4-10-1014(b) says the certification or affidavit “shall be signed or otherwise
authenticated by any trustee.” The document therefore needs trustee authentication,
but not signatures from every cotrustee.
The certification section does not prescribe an oath, acknowledgment, witness, or
notarial act. A separate transaction or recordability formality should not be stated
as a universal execution condition under § 4-10-1014.
Pertinent powers and title manner are required; property schedules are not
Subsection (a)(iv) asks for the trustee's “pertinent powers,” while subsection
(a)(viii) requires the manner of taking title to trust property. These are separate
content duties: the first addresses authority relevant to the matter, and the second
addresses how trust-property title is held or taken.
The complete list does not separately require a trust name, situs, governing-law
statement, successor trustee, court-supervision statement, property inventory, legal
description, mineral schedule, or asset-protection classification.
Dispositive terms may stay private, subject to narrow excerpts
Under § 4-10-1014(d), dispositive terms and the TIN need not appear. Subsection (e)
permits the recipient to require excerpts from the original instrument and later
amendments that designate the trustee and confer power for the pending transaction.
The recipient's express excerpt right focuses on trustee status and transaction
authority. It is not automatic access to every trust provision or the complete
instrument.
Reliance, enforcement, and demand remedies have separate tests
Section 4-10-1014(f) protects a person who relies without knowledge that the
certification or affidavit is wrong and permits assumption of the certified facts
without inquiry. Holding all or part of the trust instrument does not by itself impute
knowledge of its terms.
Subsection (g) requires good faith to enforce the transaction against trust property
as though the document were correct. Subsection (h) makes a person liable for damages
when a court finds that a demand for the trust instrument in addition to the
certification, affidavit, or excerpts was not made in good faith. It does not
expressly add costs or attorney fees. Subsection (j) preserves judicial access.
What trips people up
- The TIN is expressly optional. Wyoming places it in the numbered list but then
labels it optional and repeats that it may be omitted. - Any trustee may authenticate. That rule is separate from the reported number of
cotrustees needed to exercise trust powers. - “Affidavit” does not add a statutory oath. Section 4-10-1014 applies the same
authentication rule to both labels and states no notary ceremony. - The section states no recording consequence. It does not require recording or
state a notice, priority, conveyance, or other real-property effect.
Common questions
Must the document be called a certification rather than an affidavit?
No. Section 4-10-1014 consistently authorizes either label and applies the same rules
to both.
May a beneficiary be given this statutory substitute?
Not under subsection (a)'s substitute-document route. It applies to a person other
than a beneficiary.
Can a litigant still obtain the full trust instrument?
Yes. Section 4-10-1014(j) preserves the right to obtain it in a judicial proceeding
concerning the trust.
