Who Can Authorize Cremation in New Mexico?

This guide covers New Mexico. For the general overview, see Right of Disposition Explained.
Quick answer
New Mexico's law (N.M. Stat. §§ 24-12A-1 and 24-12A-2) decides who can authorize cremation. If the person left no valid written instructions, the right passes in this order: the spouse, a majority of adult children, the parents, and a majority of siblings (the two current sections list later kin and a caregiving adult in different orders). A majority of adult children or of siblings decides.
New Mexico’s rules on who controls a body after death are in N.M. Stat. §§ 24-12A-1 and 24-12A-2. They go beyond the simple “spouse, then children” pattern many people assume, and some details can change the outcome for a family.
What if the person left written instructions?
A person’s own cremation direction in a signed, notarized, or two-witness statement, or in a will clause, must be honored. The cited sections set out no general agent form.
Who decides if there are no written instructions?
If there are no valid written instructions, N.M. Stat. §§ 24-12A-1 and 24-12A-2 gives the right to decide in this order: the spouse, a majority of adult children, the parents, and a majority of siblings (the two current sections list later kin and a caregiving adult in different orders).
What if relatives of equal rank disagree?
A majority of adult children or of siblings decides. These sections don’t name a court procedure, and their conflicting later ranks may need to be resolved on the facts.
Can someone lose the right to decide?
The statute sets no fixed deadline. No express homicide or estrangement bar is named.
What should the family do first?
Tell the funeral home or crematory about any signed documents (a will, a health-care directive, or a disposition form recognized in New Mexico) and about any relatives who rank equally. Ask which person it is treating as the authorizing agent and what in N.M. Stat. §§ 24-12A-1 and 24-12A-2 it is relying on. If relatives disagree, many states let a provider wait for a court order or a written agreement, so ask how yours handles it. See who pays for a funeral when siblings disagree and when ex-spouses or estranged relatives claim a say in the funeral, and what to do when someone dies in New Mexico.
Add this to your Final Day Plan: your own preference between burial and cremation, in writing, and the name of the person you want to direct it, in a signed writing that meets New Mexico’s requirements. Ask a funeral home or an attorney what those are.
State law changes, and funeral homes apply it to the facts of each case. This is general educational information, not legal advice; an attorney licensed in New Mexico can tell you what applies to your family.

About this review
Everendium Editorial Team · last reviewed October 15, 2026.
Order of priority, tie rules, deadlines, and disqualifications are paraphrased from a 50-state statutory survey in which each state was checked in early October 2026 (Ezel, a legal research service, so a secondary source) and compared with the Funeral Consumers Alliance's state-by-state compilation. Full statute text was not read for any state, and the survey reflects the law as of its check date. Recommended for review by an attorney licensed in New Mexico before wide promotion.
