New Mexico: Adult Guardianship and Conservatorship Petition Requirements
The short answer
New Mexico uses separate guardianship and conservatorship tracks for personal care and financial affairs. The petitioner must prove incapacity, necessity, the lack of suitable alternatives, and least-restrictive scope by clear and convincing evidence. Unless the adult already chose counsel, the court appoints counsel with guardian-ad-litem duties, plus a qualified health-care professional and a visitor; the adult ordinarily attends and may request a jury.

| Proceeding and state terminology | Uniform Probate Code, NMSA 1978 §§ 45-5-101, 45-5-301.1–45-5-315 and 45-5-401–45-5-436. Guardianship covers personal care; conservatorship covers estate and financial affairs. The statutes use separate petitions and orders. |
|---|---|
| Who may file and where | Any interested person may seek adult guardianship (§ 45-5-303(A)). A person interested in the adult's estate, finances, or welfare—including one harmed by ineffective management—or the adult's guardian may seek conservatorship (§ 45-5-404(A)). File where the adult resides or is present; the ordering court's district is another option for an institutional placement, and a nonresident conservatorship may be filed where property lies (§§ 45-5-302, 45-5-403). |
| What the petition must contain | Petitioner and adult; spouse/committed partner, relatives and stepchildren; caregiver, counsel, payee, fiduciaries, trustees, health/financial agents and routine decision supporters; proposed appointee; functional need; alternatives considered and why insufficient; full/limited relief and requested powers/property; assets, income and communication supports (§§ 45-5-303(B), 45-5-404(B)). |
| Proof required for appointment | Capacity is presumed; petitioner bears clear-and-convincing burden (§ 45-5-303(I)). Guardian findings cover total or area-specific incapacity, continuing care/supervision/rehabilitation necessity, no suitable alternative resources, least-restrictive intervention and a qualified appointee (§ 45-5-304(C)). Conservator findings parallel these for estate/financial management (§ 45-5-407(I)). |
| Alternatives the court must address | Mandatory. Both petitions must identify alternatives considered or implemented and why insufficient; the guardian ad litem identifies all available alternatives, the visitor separates tasks manageable alone, with supports, or only through appointment, and the order must be the least restrictive intervention (§§ 45-5-303, 45-5-303.1, 45-5-304, 45-5-404, 45-5-407). |
| Notice, service, and hearing timing | Petition and hearing notice are personally served on the adult and explain rights, attendance, nature, purpose and consequences; listed persons and court-selected interested persons also receive notice (§§ 45-5-309, 45-5-405). The personal-service sections set no numeric lead time; general notice may be mailed at least 14 days before hearing, personally served, or published, subject to a good-cause change (§ 45-1-401). |
| Counsel and hearing rights | Unless the adult already has chosen counsel, appointment is mandatory and counsel performs guardian-ad-litem duties (§§ 45-5-303(D), 45-5-407(B)). The adult ordinarily attends, may present and subpoena evidence, examine the GAL, clinician and visitor, and otherwise participate; the court may hold the hearing at the adult's location, and must schedule a jury on either side's request (§§ 45-5-303(G)–(O), 45-5-407(E)–(R)). |
| Medical evidence or court evaluator | Both tracks require a court-appointed qualified health-care professional's written functional report and a court-appointed visitor who interviews the adult and proposed appointee, visits the residence, evaluates tasks with and without supports, and recommends whether appointment is appropriate (§§ 45-5-303(E), (F), 45-5-407(C), (D)). The GAL reviews both reports and may obtain independent assessments (§§ 45-5-303.1, 45-5-404.1). |
| Limits on the order | Guardianship is limited to actual functional limitations and preserves all rights not expressly restricted (§ 45-5-301.1); the order requires least-restrictive findings (§ 45-5-304). A limited conservator receives specified, restrictable powers, and the adult retains every right not granted (§ 45-5-407(J), (K)). Temporary guardian/conservator relief is separate: serious, immediate and irreparable harm, hearing within 10 business days, no more than 30 days plus one possible 60-day extension (§§ 45-5-310, 45-5-408). |

Requirements one by one
Proceeding and state terminology
New Mexico uses guardian for personal care and conservator for estate and
financial affairs. Section 45-5-101 defines the roles and measures incapacity by
functional impairment over time. The ordinary adult tracks use separate petitions:
§ 45-5-303 for guardianship and § 45-5-404 for conservatorship.
Who may file and where
Section 45-5-303(A) allows an interested person—someone interested in the
adult's welfare—to seek guardianship. Section 45-5-404(A) permits a person
interested in the adult's estate, financial affairs, or welfare, including a
person adversely affected by ineffective management, or the adult's guardian to
seek conservatorship.
Guardianship venue under § 45-5-302 is the judicial district where the adult
resides or is present, with an additional option in the district of a court that
ordered institutional admission. Section 45-5-403 uses the same basic rule for
conservatorship and adds a property-based district for a nonresident.
What the petition must contain
Sections 45-5-303(B) and 45-5-404(B) require closely parallel filings. The
petition identifies the adult, spouse or committed partner, relatives and
qualifying stepchildren, caregiver, current lawyer, representative payee,
existing guardian or conservator, trustee or custodian, veterans fiduciary,
health-care and financial agents, routine decision supporter, and proposed
appointee. It describes the functional need, property and income, communication
supports, full-versus-limited relief, and the requested powers or controlled
property.
Each filing must identify less restrictive alternatives considered or
implemented, explain why none were considered if applicable, and explain why an
alternative cannot meet the adult's need.
Proof required for appointment
The adult starts with a legal presumption of capacity. Section 45-5-303(I)
places the burden on the petitioner and requires clear and convincing evidence.
For guardianship, § 45-5-304(C) requires total or area-specific incapacity,
necessity for continuing care, supervision, and rehabilitation, no suitable
alternative resources, least-restrictive scope, and a qualified and suitable
guardian.
For conservatorship, § 45-5-401(B) supplies the threshold property-and-support
test. Section 45-5-407(I) then requires clear and convincing evidence of total
or area-specific incapacity, necessity for effective estate or financial
management, no available alternative resources, least-restrictive scope, and a
qualified and suitable conservator.
Alternatives the court must address
New Mexico builds alternatives into every stage. The petitions must discuss
them. The guardianship GAL must identify and present all available alternatives
under § 45-5-303.1. The visitor divides personal or financial tasks into those
the adult can manage alone, those manageable with supports, and those the adult
cannot manage even with help. Sections 45-5-304 and 45-5-407 make
least-restrictive intervention and the absence of suitable resources express
appointment findings. For financial needs, § 45-5-405.1 also permits a targeted
protective arrangement or single transaction without appointing a conservator.
Notice, service, and hearing timing
Sections 45-5-309 and 45-5-405 require personal service of the petition and
hearing notice on the adult. The notice explains hearing rights, attendance,
and the nature, purpose, and consequences of appointment. Listed relatives,
caregivers, fiduciaries, agents, and other court-selected interested persons
also receive notice.
The specific adult-personal-service provisions do not state a fixed lead time.
For general interested-person notice, § 45-1-401 permits mail at least 14 days
before the hearing, civil-process service, or three weekly publications with the
last at least 10 days before the hearing when identity or address cannot be
found. The court may change method or timing for good cause.
Counsel and hearing rights
Under § 45-5-303(D) and § 45-5-407(B), the court appoints counsel unless the
adult already has a lawyer of the adult's choice. Court-appointed counsel also
performs the guardian-ad-litem duties in §§ 45-5-303.1 and 45-5-404.1: interview
the adult, present the adult's stated position, review the clinician and visitor
reports, interview key participants, and obtain independent assessments if
needed.
The adult ordinarily attends. Sections 45-5-303(G) and 45-5-407(E) permit
absence only when the court finds attendance is not in the adult's best interest
because of a health-or-safety threat. The adult may present evidence, subpoena
witnesses and documents, examine the GAL, clinician, and visitor, and otherwise
participate. The court may hold the hearing at the adult's location. On request
by the petitioner or adult, the court must schedule a jury trial under
§ 45-5-303(O) or § 45-5-407(R).
Medical evidence or court evaluator
Both evidence tracks are mandatory. Section 45-5-303(E) requires a
court-appointed qualified health-care professional to report on the nature and
degree of incapacity, intellectual, developmental, and social functioning, and
the ability to make health-care decisions and manage daily activities. Section
45-5-407(C) requires the parallel financial report on the ability to manage the
estate or financial affairs.
The court also appoints a visitor under § 45-5-303(F) or § 45-5-407(D). The
visitor interviews the adult and proposed appointee, visits the residence,
evaluates needs and supported functioning, and recommends whether the proposed
appointment is appropriate. The GAL reviews both reports before filing a report
prior to the hearing.
Limits on the order
Section 45-5-301.1 limits guardianship to the adult's actual functional mental
and physical limitations and preserves every right not expressly limited or
granted to the guardian. Section 45-5-304 requires clear findings for either a
full or limited guardian and tells the adult about appeal and later alteration
or termination.
Section 45-5-407(J) requires a limited conservator when the adult can manage
some but not all financial matters. The court specifies and may further restrict
each power. Subsection (K) preserves every legal and civil right not specifically
granted to the conservator, and subsection (S) requires notice of appeal and
review rights.
Temporary relief is separate. Sections 45-5-310 and 45-5-408 require serious,
immediate, and irreparable harm, a hearing within ten business days, specified
powers, and an initial term no longer than 30 days, with one possible extension
of no more than 60 days for good cause. An ex parte appointment triggers
personal service on the adult and counsel within 24 hours.
What trips people up
New Mexico does not use only a medical certificate. The ordinary case requires
three separate professional roles: the adult's lawyer acting with GAL duties, a
court-appointed qualified health-care professional, and a court-appointed
visitor. The clinician addresses functional capacity; the visitor investigates
real-world tasks, supports, residence, and the proposed appointee; the GAL
presents the adult's position and tests the other reports.
The hearing is also not automatically a bench-only proceeding. A jury does not
occur by default, but § 45-5-303(O) and § 45-5-407(R) say the court shall
schedule one when the petitioner or adult requests it.
Common questions
Can the adult simply consent to conservatorship?
No. Section 45-5-407(F) says the court shall not permit the person to consent to
appointment. The petitioner still must prove the statutory case by clear and
convincing evidence.
Is a diagnosis by itself enough?
No. Section 45-5-101 defines incapacity through functional impairment shown
over time, and §§ 45-5-304 and 45-5-407 require necessity, lack of suitable
alternatives, and least-restrictive findings in addition to incapacity.
Can the court solve one financial problem without appointing a conservator?
Yes. Section 45-5-405.1 allows a protective arrangement or targeted transaction,
including benefit, payment, property, trust, contract, or claim-settlement relief,
when the statutory basis exists but a full conservatorship is unnecessary.
How long can a temporary appointment last?
The initial temporary guardianship or conservatorship may last no more than 30
days. After a hearing and good-cause showing, the court may extend it once for
no more than 60 additional days under §§ 45-5-310 and 45-5-408.
