Requirements one by one

Governing law and covered interests

NMSA 1978 §§ 45-2-1101 through 45-2-1116 contain New Mexico's Uniform Disclaimer of Property Interests Act. Sections 45-2-1103 and 45-2-1105 cover any interest in or power over property whenever created, including interests passing by will, intestacy, trust, beneficiary designation, survivorship arrangement, or power of appointment.

Whole, partial, and conditional disclaimer

Section 45-2-1105 permits a whole or partial disclaimer. A partial disclaimer may be written as a fraction, percentage, monetary amount, term of years, limitation of a power, or another interest or estate. The act does not separately state whether a disclaimer may be conditional.

Jointly held property follows § 45-2-1107. The surviving holder may disclaim the greater of a fraction based on the holders alive immediately before death or all value above the contribution furnished by the survivor.

Writing or record and required contents

Under § 45-2-1105(C), the disclaimer may be a paper writing or another tangible, electronic, or retrievable record. It must declare the disclaimer, describe the interest or power, be signed, and be delivered or filed under § 45-2-1112. The act does not require an original, legal description, tax recital, or supporting document as part of the general state-law minimum. It defines an electronic record but does not separately define an electronic-signature method.

Signature, witnesses, acknowledgment, and notary

The execution requirement is the signature of the person making the disclaimer. The act states no witness, acknowledgment, notarization, attestation, oath, or sworn-verification rule.

State deadline, irrevocability, and federal-tax overlay

The act states no fixed New Mexico validity deadline. The beneficiary must act before a bar in § 45-2-1113 applies, and another law may impose an additional bar or limitation. Under § 45-2-1105(E), the disclaimer becomes irrevocable at the later of delivery or filing under § 45-2-1112 and statutory effectiveness under §§ 45-2-1106 through 45-2-1111.

Federal tax qualification is separate. Section 45-2-1114 recognizes a disclaimer or transfer treated under federal tax law as never transferred to the disclaimant. The federal statute requires receipt within nine months after the later of the transfer or the disclaimant reaching age 21, plus no prior acceptance and passage without the disclaimant's direction.

Delivery, filing, and recipient

Section 45-2-1112 permits personal delivery, first-class mail, or another method likely to result in receipt. The route depends on the asset:

• For a will or intestacy interest, deliver to the personal representative; file with the appointing court if none is serving.
• For a testamentary trust, deliver to the trustee, then the personal representative if no trustee serves, with a court fallback if neither serves.
• For an inter vivos trust, deliver to the trustee or use the court fallback; while the trust is revocable, deliver to the settlor or transferor.
• For a beneficiary designation, deliver to its creator before it becomes irrevocable. After irrevocability, deliver a personal-property disclaimer to the distributor; real property uses the recording route below.
• For jointly held property, deliver to the person who takes because of the disclaimer.
• For an object, default taker, or appointee under a power of appointment, deliver to the holder or named fiduciary, with a court fallback if none serves.

Real-property recording and notice

New Mexico separates two recording rules. After a beneficiary designation becomes irrevocable, § 45-2-1112(G)(2) requires a disclaimer of the designated real-property interest to be recorded with the county clerk in every county where the property lies.

For other property, § 45-2-1115 permits filing, recording, or registration when the instrument transferring the underlying interest may or must be recorded. Except for the mandatory beneficiary-designation route, nonrecording does not affect validity between the disclaimant and the people who take because of the disclaimer. The act states no legal-description requirement or broader purchaser or lienholder consequence.

Acceptance, transfer, insolvency, and creditor bars

Section 45-2-1113 bars a disclaimer after a written waiver. Before effectiveness, acceptance, voluntary assignment, conveyance, encumbrance, pledge, transfer or a contract to do so, and a judicial sale also bar it. Another law may supply an additional bar or limitation. A barred power disclaimer is ineffective; a barred interest disclaimer operates as a transfer to the people who otherwise would have taken under the act.

The act states no separate insolvency or ordinary creditor-claim bar.

Effective date and destination

Under § 45-2-1106, a disclaimer of an instrument-created interest takes effect when the instrument becomes irrevocable; an intestacy interest takes effect at death. The instrument's own disclaimer-disposition clause controls first. Without one, an individual is generally treated as dying immediately before distribution, and descendants who would take by representation must survive the distribution time.

New Mexico adds a special estate-destination rule. If deemed death would send the interest to the disclaimant's estate, the interest instead passes first to the disclaimant's surviving descendants by representation and, if none survive, to the transferor's intestate successors while excluding the disclaimant. The disclaimant's own future interest is not accelerated.

For jointly held property, § 45-2-1107 makes the disclaimer effective at the other holder's death and passes the disclaimed portion as though the survivor had predeceased that holder. The disclaimant does not choose the successor.

What trips people up

• Importing the federal deadline into New Mexico validity law. The act has no fixed nine-month clock; the federal period governs a separate tax status.
• Using one recipient for every asset. The statute changes the recipient for probate, trust, beneficiary-designation, survivorship, and power interests.
• Flattening the real-property rules. Recording is mandatory for one post-irrevocability beneficiary-designation route and otherwise permissive under the surveyed act.
• Letting the interest fall into the disclaimant's estate. New Mexico redirects that default to surviving descendants or the transferor's intestate successors.

Common questions

Does a New Mexico disclaimer need a notary or witnesses? The act requires a signature but states no witness, acknowledgment, oath, or notarization rule.

Can the disclaimer be an electronic record? Yes. The act includes information stored electronically if it is retrievable in perceivable form, but it does not separately define how that electronic record must be signed.

Must every real-property disclaimer be recorded? Not under this act. The mandatory route applies to a real-property interest under a beneficiary designation after that designation becomes irrevocable; § 45-2-1115 makes recording permissive in the general case.

What happens if I already assigned the interest? A voluntary assignment or contract to transfer before effectiveness is an express bar. The barred interest disclaimer then operates as a transfer to the people who otherwise would take.
