New Mexico: Revocable Living Trust Creation Requirements

Requirements one by one

Governing law and scope

New Mexico enacted the Uniform Trust Code in 2003, effective July 1 of that year.
It sits at NMSA 1978, §§ 46A-1-101 through 46A-11-1104 and supplies nearly every
rule below.

One thing it deliberately does not supply is a writing requirement for land. The
code reaches outside itself for that, and the outside rule is not in the statute
books either. See the instrument dimension below.

Settlor capacity and intent

§ 46A-6-601 sets the standard by reference: the capacity to create, amend,
revoke, or add property to a revocable trust "is the same as that required to
make a will." That is the lower testamentary standard, not the higher standard
some states apply to contracts.

§ 46A-4-402(A)(2) then requires that the settlor "indicates an intention to
create the trust." Intention must be manifested, but no particular words are
prescribed.

Creation method and effective time

§ 46A-4-401 gives three routes. The first is a transfer of property to
another person as trustee, either during life or at death. The second is the one
most home-made living trusts use: a declaration by the owner of property that
the owner holds identifiable property as trustee. The third is exercising a
power of appointment in favor of a trustee.

The declaration route matters because it means the settlor does not have to
convey anything to a third party to create the trust. What the settlor must have
is identifiable property held in the trustee capacity.

Trust property and funding

The code sets no dollar minimum and no separate delivery ceremony. Section
46A-4-401(B)'s word is "identifiable" — the property has to be capable of being
identified as the trust's.

This is the point where creating a trust and funding it diverge. A validly
created trust that never receives an asset controls nothing, and moving each
asset in is a separate act governed by that asset's own transfer rules.

Beneficiary and purpose

§ 46A-4-402(A)(3) requires a definite beneficiary unless the trust is
charitable, for the care of an animal, or for another noncharitable purpose under
the code's own sections. Subsection (B) defines definite generously: a
beneficiary is definite "if the beneficiary can be ascertained now or in the
future," subject to any applicable rule against perpetuities. A class that will
close later can qualify.

§ 46A-4-404 adds two limits. The purposes must be "lawful, not contrary to
public policy and possible to achieve," and the trust and its terms "must be for
the benefit of its beneficiaries."

Trustee eligibility and same-person roles

Two of the five creation requirements are about the trustee. Section
46A-4-402(A)(4) requires that "the trustee has duties to perform," and (A)(5)
requires that "the same person is not the sole trustee and sole beneficiary."

That second rule is narrower than it first looks, and it is the one people
misread. It bars the complete merger of the two roles in one person. A settlor
may name herself as trustee and also be a beneficiary, so long as she is not
both the only trustee and the only beneficiary — which is why ordinary living
trusts routinely name remainder beneficiaries.

§ 46A-7-701(A) makes acceptance flexible: a designated trustee accepts by
the method the terms provide, or by accepting delivery of trust property,
exercising powers, performing duties, "or otherwise indicating acceptance." Under
(B), a designated trustee who does not accept within a reasonable time after
learning of the designation is deemed to have rejected.

Instrument, signature, witness, and notary

The Uniform Trust Code imposes no execution formalities at all. § 46A-4-407
says a trust "need not be evidenced by a trust instrument," and adds a proof rule
rather than a form rule: an oral trust and its terms "may be established only by
clear and convincing evidence."

But that section opens with a carve-out — "Except as required by a statute other
than the Uniform Trust Code" — and for real property, such a rule exists. The
New Mexico Supreme Court stated it in Aragon v. Rio Costilla Cooperative
Livestock Ass'n: "the declaration and creation of a trust in land falls under the
English statute of frauds, . . . 29 Car. 2, ch. 3, § 7 . . . which is part of our
common law. Thus, while an express trust in real estate need not be created in
writing, some memorandum manifesting and proving the trust must exist."

That rule survives the UTC's arrival. § 46A-1-106 provides that "the common
law of trusts and principles of equity supplement the Uniform Trust Code, except
to the extent modified by that code or another statute of this state," and nothing
in the code modifies the land rule. New Mexico received the English statute
through § 38-1-3, which makes the common law "the rule of practice and decision"
in its courts.

The practical upshot for an ordinary home trust: no witnesses and no notary are
required, but the trust must be evidenced by a signed memorandum if it holds real
property.

Revocability default and reserved power

§ 46A-6-602(A) reverses the old common-law default: "Unless the terms of a
trust expressly provide that the trust is irrevocable, the settlor may revoke or
amend the trust." Revocability does not have to be reserved.

That default has a hard date limit. The same subsection says it "does not apply
to a trust created under an instrument executed before July 1, 2003." For older
instruments, the pre-code default applies instead.

Subsection (C) sets the method. If the terms provide one, substantial compliance
with it works. If the terms provide none, or provide one that is not expressly
made exclusive, the settlor may revoke or amend by a later will or codicil that
expressly refers to the trust or specifically devises property that would
otherwise pass under it, or by "any other method manifesting clear and convincing
evidence of the settlor's intent."

Registration, recording, and third-party effect

New Mexico has no trust-registration system. Nothing needs to be filed with any
court or agency to create a living trust, and the instrument itself is not
recorded.

Recording enters only through the assets. A deed moving real property into the
trust must be acknowledged before it can be recorded under § 14-8-4(A), and under
§ 14-9-3 an unrecorded instrument does not affect the rights of a good-faith
purchaser, mortgagee, or judgment lien creditor without knowledge of it.

§ 46A-10-1013(A) supplies the privacy tool: instead of furnishing a copy of
the trust instrument to a person other than a beneficiary, the trustee may furnish
a certification of trust containing the listed facts.

What trips people up

The "outside statute" in § 46A-4-407 is not in the statute books. Someone
reading the Uniform Trust Code alone will conclude that New Mexico requires no
writing for any trust. The land rule that the carve-out points to is the received
English Statute of Frauds § 7, and it is found only in the case law. A trust meant
to hold a house needs a written memorandum.

Sole trustee and sole beneficiary is one rule, not two. Section
46A-4-402(A)(5) does not stop a settlor from serving as her own trustee, and it
does not stop her from being a beneficiary. It stops the two roles from collapsing
entirely into one person with no one else holding a beneficial interest.

The revocability default has a 2003 cutoff. Instruments executed before
July 1, 2003 do not get the "revocable unless it says otherwise" rule. For an old
family trust, the terms and the prior law govern.

Creation is not funding. Every rule above is about whether a trust exists.
Whether the house, the bank account, or the brokerage account is actually inside
it depends on separate transfer steps for each asset.

Common questions

Can a New Mexico living trust be oral? For personal property, the code allows
it, but § 46A-4-407 requires clear and convincing evidence of both the creation
and the terms. For real property, Aragon requires a memorandum manifesting and
proving the trust. Oral is a poor plan either way.

Does the trust have to be notarized? No provision of the New Mexico Uniform
Trust Code requires a notary to create a trust. Notarization becomes relevant when
a deed transferring real property into the trust is presented for recording, since
§ 14-8-4(A) bars recording an unacknowledged instrument.

Must the trust be filed anywhere? No. New Mexico has no trust registration.
The only public filing in a typical funding is the deed for real property.

Does a bank get to see the whole trust document? § 46A-10-1013(A) lets
the trustee give a certification of trust to a person other than a beneficiary
instead of the full instrument.
