There is a conversation most New Mexico families never have. Not because they don't care, but because it feels like the kind of thing you deal with later, when the time is right, when things slow down.
Then something happens. A hospitalization. A diagnosis. A sudden accident. And the time that felt distant is suddenly right now, with a doctor in a hallway asking questions that nobody prepared for.
An advance healthcare directive exists so that conversation happens on your terms, not in a crisis. It tells your medical team what you want and names someone you trust to speak for you when you can't.
What Is an Advance Healthcare Directive?
An advance healthcare directive is a written, legally binding document that does two things: it records your wishes about medical treatment, and it names a person, your healthcare agent, to make decisions on your behalf when you cannot.
New Mexico recognizes advance directives under the New Mexico Uniform Health-Care Decisions Act, codified at NMSA 1978, Chapter 24, Article 7A. That law sets out the requirements for a valid directive, the duties of a healthcare agent, and the obligations of healthcare providers who receive one.
The phrase "advance directive" is an umbrella term. In New Mexico, it typically encompasses both a living will (your written instructions about specific treatments) and a healthcare power of attorney (your designation of a person to carry out those instructions). Some people execute both in a single combined document. Others execute them separately. Either approach is valid as long as the documents meet New Mexico's execution requirements.
The Two Parts of a New Mexico Advance Directive
Your Healthcare Instructions (Living Will)
A living will is the part of your advance directive where you record your specific wishes about medical treatment. Common topics include:
-
Whether you want life-sustaining treatment continued if you are in a terminal condition with no reasonable expectation of recovery
-
Whether you want artificial nutrition and hydration (tube feeding) if you are permanently unconscious
-
Your preferences about pain management and comfort care
-
Whether you want CPR attempted if your heart stops
-
Any other specific treatment preferences that matter to you
A living will is not a rigid script. It is a record of your values and priorities that gives your healthcare agent and your medical team context for decisions the document itself may not have anticipated. The more specific and personal it is, the more useful it becomes.
Your Healthcare Agent (Medical POA)
The second part of your advance directive names a healthcare agent, the person authorized to make medical decisions on your behalf when you cannot make them yourself. This is sometimes called a healthcare power of attorney or a healthcare proxy.
Your healthcare agent steps in when your doctors determine you lack capacity to make or communicate your own decisions. Until that point, the authority is entirely yours. Once it activates, your agent has broad authority to consent to or refuse treatment, direct your care, access your medical records, and make decisions your living will did not specifically address.
The relationship between a living will and a healthcare agent is intentional. Your living will records what you want. Your healthcare agent interprets those wishes in real time, in situations that may be more complicated than a form anticipated. Both parts of the directive work together, and both matter.
What Decisions Can an Advance Directive Cover?
A well-drafted New Mexico advance directive can address a wide range of medical scenarios, including:
-
Terminal illness. If you are diagnosed with a terminal condition and your doctors determine that treatment would only prolong dying rather than restore meaningful function, your directive can specify whether you want life-sustaining measures continued or withdrawn.
-
Permanent unconsciousness. If you are in a persistent vegetative state with no reasonable expectation of recovery, your directive can address whether you want artificial nutrition, hydration, and other interventions continued.
-
End-stage conditions. Some people include instructions for conditions like advanced dementia, where the ability to recognize loved ones or communicate meaningfully is gone.
-
Pain and comfort care. Regardless of other treatment decisions, most directives specify that comfort care and pain management should always be provided.
-
Organ donation. An advance directive is an appropriate place to record your wishes about organ, tissue, or body donation, though New Mexico also maintains a donor registry through the MVD.
An advance directive does not need to address every possible scenario. What it does need to reflect is your actual values, your definition of a life worth sustaining, and your threshold for intervention. That is a personal conversation, and an estate planning attorney can help you think through it before putting it on paper.
Do Not Resuscitate Orders and POLST Forms in New Mexico
Two additional documents are worth understanding alongside an advance directive.
A Do Not Resuscitate order, commonly called a DNR, is a physician's order directing medical personnel not to perform CPR if your heart or breathing stops. A DNR is a medical order, not an estate planning document. It must be signed by a physician and, in New Mexico, is typically used in hospital or nursing facility settings. Your advance directive can express a preference about CPR, but a separate DNR order is required for that preference to be immediately actionable by emergency responders.
A POLST form, which stands for Physician Orders for Life-Sustaining Treatment, is a more detailed medical order that covers a range of treatment preferences beyond CPR, including hospitalization, feeding tubes, and comfort-focused care. In New Mexico, POLST forms are typically used for people with serious illness or advanced age who want their treatment preferences immediately visible to any provider. Unlike an advance directive, a POLST is a medical order completed with and signed by a physician.
An advance directive, a DNR, and a POLST serve different but complementary purposes. An estate planning attorney can help you understand which documents are appropriate for your situation and ensure they work together rather than conflict.
How to Make an Advance Directive Valid in New Mexico
Under the New Mexico Uniform Health-Care Decisions Act, an advance directive must meet certain requirements to be legally valid:
-
The directive must be in writing
-
It must be signed by the person making it, or by another individual at the person's direction if they are physically unable to sign
-
It must be signed in the presence of two adult witnesses, or acknowledged before a notary public
Witnesses cannot be the person's healthcare agent, a healthcare provider, or an employee of a healthcare provider. These restrictions exist to prevent conflicts of interest at the moment the document is executed.
Once executed, your advance directive should be given to your healthcare agent, your primary care physician, and any specialists involved in your care. If you are admitted to a hospital in Albuquerque, Las Cruces, or anywhere else in New Mexico, the facility will typically ask whether you have an advance directive and may request a copy for your file.
A document that exists but cannot be located in an emergency provides little protection. Keep a copy somewhere accessible and make sure the people who need it know where to find it.
What Happens Without an Advance Directive?
Without an advance directive, medical decisions default to whoever New Mexico law recognizes as your surrogate decision-maker. Under NMSA 1978, Chapter 24, Article 7A, that hierarchy generally runs: a court-appointed guardian, then a spouse or domestic partner, then adult children, then parents, then adult siblings, then other relatives.
That hierarchy assumes agreement. When family members disagree about a patient's care, a default rule does not resolve the conflict. Hospitals are placed in a difficult position. Family relationships are strained at exactly the wrong moment. And the patient's actual wishes, never recorded, may not be reflected in the outcome.
There is also the question of what happens when no family member is available or willing to serve. In that case, a healthcare provider may be left making decisions without meaningful guidance, based on what they believe a reasonable person would want rather than what you actually wanted.
An advance directive removes the ambiguity. It gives your medical team clear direction, your family a defined decision-maker, and you the assurance that your wishes will be honored.

Frequently Asked Questions
What is the difference between a living will and an advance directive in New Mexico?
A living will is the portion of an advance directive that records your specific wishes about medical treatment. An advance directive is the broader document that includes both your written instructions and your designation of a healthcare agent to carry them out. In common usage the terms are sometimes used interchangeably, but in New Mexico a complete advance directive typically includes both components.
Who should I name as my healthcare agent in New Mexico?
Your healthcare agent should be someone you trust completely, who understands your values, and who can advocate clearly under pressure. They do not need medical expertise, but they do need emotional steadiness and the willingness to make difficult decisions on your behalf. Always name a successor agent in case your first choice is unavailable when needed.
Can I change or revoke my advance directive in New Mexico?
Yes. You can revoke or amend your advance directive at any time while you have capacity to do so. Revocation can be written or verbal, and should be communicated to your healthcare agent, your physician, and any facility that has a copy on file. If you create a new directive, it should explicitly state that it supersedes all prior directives.
Does my advance directive work if I am treated outside New Mexico?
New Mexico advance directives are generally recognized in other states, though the specific requirements vary. If you spend significant time in another state, particularly for seasonal living or extended family stays, it is worth discussing with your attorney whether a second directive executed under that state's requirements would provide more reliable protection.
Will my doctor follow my advance directive even if they disagree with my wishes?
Generally, yes. Under the New Mexico Uniform Health-Care Decisions Act, healthcare providers are required to comply with a valid advance directive or transfer your care to a provider who will. A provider who has a conscientious objection to a particular directive must inform your healthcare agent and facilitate a transfer of care. Your wishes are legally binding, not merely advisory.
