Missouri: Certification of Trust Requirements

Requirements one by one

Missouri requires eight listed fact groups

Missouri Revised Statutes § 456.10-1013.1 lets a trustee furnish a certification
instead of the trust instrument to a person other than a beneficiary. It requires the
trust's existence and execution date, settlor identity, the acting trustee's identity
and address, trustee powers, revocability and the revocation-power holder, cotrustee
authority, the taxpayer identification number, and the manner of taking title.

Section 456.10-1013.3 adds a required statement that the trust has not been revoked,
modified, or amended in a way that makes the certification's representations
incorrect.

All trustees sign, and the recipient controls extra authentication

Section 456.10-1013.2 says the certification “must be signed by all the trustees.”
That signer rule is separate from the required statement about whether all or fewer
cotrustees are needed to exercise trust powers.

The same subsection allows the third party to require the certification to be
acknowledged or guaranteed. The statute does not impose either formality on every
certification automatically; it gives the recipient the choice to require one.

The TIN is mandatory, while dispositive terms may stay private

Section 456.10-1013.1(7) includes the trust's taxpayer identification number in the
mandatory content list without a transaction-necessity qualifier.

Under § 456.10-1013.4, the certification need not contain dispositive terms. The
recipient may nevertheless require the limited excerpts described in subsection 5:
provisions designating the trustee and conferring the power to act in the pending
transaction. The statute does not turn that limited excerpt right into automatic access
to every trust term.

Reliance and transaction enforcement have distinct standards

Section 456.10-1013.6 protects a person who relies without knowledge that the
certification is wrong and permits that person to assume the certified facts without
inquiry. Possessing all or part of the trust instrument does not by itself impute
knowledge of its terms.

Subsection 7 separately requires good faith for enforcement. A person who in good faith
enters a transaction in reliance on the certification may enforce it against trust
property as if the representations were correct.

A bad-faith full-instrument demand creates a damages remedy

Section 456.10-1013.8 makes a person liable for damages if a court determines that a
demand for the trust instrument, in addition to the certification or excerpts, was not
made in good faith. The subsection says “damages”; it does not expressly add costs,
expenses, or attorney fees. Subsection 9 preserves access to the trust instrument in a
judicial proceeding concerning the trust.

What trips people up

• The taxpayer identification number is a statutory field. Missouri does not
  condition it on transaction necessity or make it optional.
• Every trustee signs the certification. A trust may let fewer trustees exercise
  particular powers, but § 456.10-1013.2 still requires all trustees' signatures on
  this substitute document.
• Acknowledgment or guarantee is recipient-driven. The statute permits the third
  party to require one; it does not universally require notarization.
• The statute supplies no certification-specific recording effect. Section
  456.10-1013 does not say recording creates constructive notice of the trust or
  trustee authority.

Common questions

Must the certification include the trust's TIN?

Yes. Section 456.10-1013.1(7) places the taxpayer identification number in the
mandatory content list.

Can one trustee sign when the trust lets one trustee act alone?

No. Section 456.10-1013.2 requires all trustees to sign the certification even though
subsection 1(6) separately reports whether fewer trustees may exercise trust powers.

Does the certification always have to be notarized?

Not automatically under this section. A third party may require the certification to
be acknowledged or guaranteed under § 456.10-1013.2.

What can the recipient demand beyond the certification?

Section 456.10-1013.5 permits excerpts that designate the trustee and confer power for
the pending transaction. A bad-faith demand for the full instrument in addition to the
certification or excerpts can produce damages under subsection 8.
