A. Appointment. In any proceeding when custody of a minor child is contested under Chapter 40, NMSA 1978 the court may appoint a guardian ad litem on the court’s motion or upon the motion of any party, as set forth in this rule. The guardian ad litem serves as an arm of the court and assists the court in discharging its duty to adjudicate the child’s best interests.

B. Order. The appointment order shall be written in substantial conformity with Form 4-402 NMRA. The order shall specify the guardian ad litem’s role, tasks, duties, any limitations, the reasons for the appointment and the duration of the appointment. The order shall authorize communication between the guardian ad litem and any mental health professional, medical professional, or other individuals providing services to parents, children, or other parties in the case and shall order the parties and minor children over the age of fourteen (14) to sign any releases requested by the guardian ad litem.

C. Designation. The guardian ad litem appointed under this rule is a “best interests attorney” who shall provide independent services to protect the child’s best interests without being bound by the child’s or either party’s directive or objectives and who shall make findings and recommendations. This rule shall not limit the court’s ability to appoint an expert pursuant to Rule 11-706 NMRA or a special master pursuant to Rule 1-053 NMRA.

D. Prohibited delegation. In no event shall the court delegate the ultimate determination of the child’s best interests, unless the parties have agreed to arbitrate such issues under Section 40-4-7.2 NMSA 1978.

E. Factors. In determining whether an appointment will be made, the court may consider relevant factors, including the following:

(1) the wishes of the parents or other parties;

(2) the age of the child;

(3) the contentiousness of the parties or other dynamics affecting the child, including past or present mental health issues of a party or a household member;

(4) the extent to which the appointment will assist the court by providing factual information useful to the court in determining the child’s best interest;

(5) the ability of the parties to pay;

(6) the views or concerns expressed by the child;

(7) the requests for extraordinary remedies, including supervised visitation;

(8) a proposed relocation;

(9) the likelihood that the child will be called as a witness or be examined by the court in chambers;

(10) past or present substance abuse, sexual abuse, emotional abuse, or domestic abuse by, or to, a party, the child, or a household member;

(11) disputes as to paternity;

(12) interference, or threatened interference, with custody or parenting time, including abduction;

(13) special physical, educational, or mental health needs of the child;

(14) inappropriate adult influence on, or manipulation of, the child;

(15) the extent to which the litigation process is harmful to the child;

(16) whether the child’s needs can be protected through the limitation of the appointment to a specific issue; and

(17) any other relevant factors.

F. Duties. The guardian ad litem shall have the following duties, in addition to other duties stated in the order:

(1) if the child is age six (6) or older, interviewing the child face-to-face outside the presence of all parties and counsel; interviewing all parties in conformity with Rule 16-402 NMRA and the order appointing the guardian ad litem; interviewing any therapist for the child; and interviewing other lay persons, mental health professionals, medical professionals, or other individuals providing services to parents, children, or other parties in the case at the guardian ad litem’s or court’s discretion. If the child is under the age of six (6), the guardian ad litem may interview the child outside the presence of the parties and counsel at the guardian ad litem’s discretion;

(2) determining the child’s wishes, if appropriate;

(3) protecting the best interests of the child or children in the matter in which the guardian ad litem was appointed;

(4) serving a written report of investigation and separate written recommendations to all parties and counsel at least eleven (11) days before the recommendations are filed with the court;

(5) filing the recommendations with the court and providing written notice to the parties of the following:

(a) the deadline for submitting a stipulated order adopting the recommendations as provided in Subparagraph (G)(1) of this rule;

(b) the deadline for filing objections to the recommendations as provided in Subparagraph (G)(2) of this rule;

(6) in the case of an emergency, filing emergency recommendations with the court and requesting a hearing without regard to Subparagraphs (4) and (5) of this Paragraph.

G. Guardian ad litem recommendations.

(1) If the parties agree to adopt the guardian ad litem recommendations, they shall submit a stipulated order adopting the recommendations within eleven (11) days after the recommendations are filed.

(2) If one or both of the parties does not agree to adopt the recommendations, such party may file objections to the recommendations and a request for hearing on the objections within eleven (11) days after the recommendations are filed. Objections must identify the specific portions of the guardian ad litem’s recommendations to which the party objects. The court will set a hearing on the objections to be held as soon as practicable after the filing of the objections. If a party files objections to emergency recommendations filed by a guardian ad litem under Subparagraph (F)(6) of this rule, the court shall set a hearing to be held within twenty (20) days of the filing of the objections.

(3) A failure to file timely objections to the recommendations of the guardian ad litem shall be deemed a waiver of the right to object, and the court shall, without the necessity of a hearing, enter an order adopting the guardian ad litem’s recommendations.

H. Duties to the child. A guardian ad litem, in a manner appropriate to the child’s developmental level, shall:

(1) explain the role of the guardian ad litem to the child;

The guardian ad litem’s limited waiver of the privilege for these purposes does not constitute a waiver of the privilege for any matter not specifically disclosed or to any person or agency to whom the information is not specifically disclosed.

(c) The child’s parent or legal guardian may not claim the privilege or interfere with the guardian ad litem’s assertion or waiver of the privilege.

(4) Construction. This paragraph shall be construed to protect the best interests of the child.

[Provisionally approved by Supreme Court Order No. 06-8300-018, effective August 21, 2006; as amended by Supreme Court Order No. 07-8300-021, effective August 21, 2007; as amended by Supreme Court Order No. 17-8300-017, effective in all cases pending or filed on or after December 31, 2017.]

Committee Commentary

A guardian ad litem’s authority to claim or waive the privilege on behalf of the child under Subparagraph (I)(3) extends to any communication with the child that would be privileged if made by an adult. See, e.g., Rule 11-504(C)(2)(d) NMRA (providing that the privilege for communications between a patient and the patient’s physician, psychotherapist, or state or nationally licensed mental-health therapist may be claimed by “any other person included in the communication to further the patient’s interest”).

Paragraph J permits a guardian ad litem to call witnesses and to provide a verbal report and recommendations at any hearing or trial in the matter in which the guardian ad litem is appointed. Such participation does not implicate Rule 16-307 NMRA, which prohibits a lawyer from acting as an advocate in any proceeding in which the lawyer is likely to be a necessary witness. A guardian ad litem is, by definition, a “best interests attorney” who acts as “an arm of the court” and therefore is not an advocate for the purposes of Rule 16-307. If a guardian ad litem chooses to provide a verbal report, facts or data relied on by a guardian ad litem in forming an opinion in the case need not be admissible for the guardian ad litem’s opinion to be admitted. See Rule 11-703 NMRA; Thomas v. Thomas, 1999-NMCA-135, ¶ 25, 128 N.M. 177, 991 P.2d 7.

Plain-English Summary

This rule provides for a guardian ad litem in contested custody cases under Chapter 40. Appointed on the court’s or a party’s motion, the guardian ad litem serves as an arm of the court—a “best interests attorney” who acts independently of the child’s or either party’s directives and makes findings and recommendations. The appointment order, in substantial conformity with the approved form, specifies the role, tasks, and duration; the court may not delegate the ultimate best-interests determination. The rule lists factors guiding whether to appoint, such as the child’s age, the parties’ contentiousness, abuse history, and the ability to pay.

The guardian ad litem’s duties include interviewing the child (face-to-face if age six or older) and the parties, protecting the child’s best interests, and serving a written report and recommendations on the parties at least eleven days before filing. If the parties agree, they submit a stipulated order within eleven days; if not, a party may file specific objections and request a hearing within eleven days, and failing to object timely waives the right and lets the court adopt the recommendations without a hearing. The rule also protects the child–guardian communications as privileged and addresses fees and costs.
