To get a guardian ad litem appointed, you file a written motion in the court already handling your case, explaining why the child or incapacitated adult needs an independent investigator, and then argue the request at a hearing. In some situations the judge will appoint one without being asked, so before drafting anything, check whether your case is one where appointment is automatic.
Decide What You Actually Need
Before filing, be clear on which role you want, because judges appoint both and they do different jobs. A guardian ad litem (GAL) advocates for what the GAL believes is in the person’s best interests, even if the person disagrees. An attorney ad litem represents the person’s own expressed wishes, the way any lawyer represents a client’s stated goals.
The distinction changes outcomes. A 14-year-old in a custody case might insist she wants to live with one parent. An attorney ad litem would argue for that outcome. A GAL might investigate, conclude the other parent’s home is better for her, and recommend accordingly. Some states allow one person to fill both roles; others prohibit it. The Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act requires that a GAL not be the same person as the attorney representing the respondent in guardianship proceedings.
If your case involves a child old enough to have preferences, or an adult with some capacity to communicate wishes, decide which appointment you want before drafting your motion. Asking for the wrong one wastes a hearing.
Check Whether the Judge Will Appoint One Automatically
Not every case requires a motion. Federal law creates one of the strongest appointment mandates: under the Child Abuse Prevention and Treatment Act, every state that receives federal child abuse prevention funding must appoint a GAL in any child abuse or neglect case that reaches a courtroom. The statute lets that GAL be an attorney, a Court Appointed Special Advocate (CASA volunteer), or both, and requires training in child development.1Office of the Law Revision Counsel. 42 USC 5106a – Grants to States for Child Abuse or Neglect Prevention and Treatment Programs
Federal Rule of Civil Procedure 17(c) goes further in federal court, requiring the court to appoint a GAL or take other protective action whenever a minor or incompetent person is a party to a lawsuit and doesn’t already have a representative.2Legal Information Institute.

Outside those mandates, state law controls, and most states leave it to the judge’s discretion in family and guardianship matters. GALs are commonly appointed in custody and divorce disputes, adult guardianship and conservatorship cases, probate matters involving minors who stand to inherit, personal injury lawsuits with a minor or incapacitated plaintiff, and immigration cases involving unaccompanied children. If your case falls in a discretionary category, you’ll need to ask.
Drafting the Motion
The motion is a written request to the court that explains why a GAL is needed and cites the statute in your jurisdiction authorizing the appointment. Look up the local rule before you draft, because format, page limits, and filing fees vary.
Three things belong in the motion:
- Why the case requires independent representation. Describe the specific circumstances. In a custody case, that might be conflicting parental claims, allegations of abuse or neglect, or a child with special needs whose interests differ from both parents’ positions.
- Why existing representation is insufficient. If both parents have attorneys but nobody is independently investigating the child’s actual living situation, say so.
- What you want the GAL to do. Identify the scope of investigation you’re requesting. Courts appreciate specificity because it helps them define the GAL’s authority in the appointment order.
Many courts require supporting affidavits or declarations. These sworn statements provide factual detail: descriptions of the child’s circumstances, evidence of a party’s incapacity, a therapist’s observations, school records. A motion backed by concrete documentation stands a much better chance than a general assertion that the child needs protection.
Address likely objections in the motion itself. If the other party will argue that a GAL is unnecessary or too expensive, address those points directly. Judges respond better to motions that show the filer has considered the full picture.
If cost is a concern, file a financial affidavit alongside the motion. Raising affordability at the drafting stage gives the court information it needs to structure payment. Waiting until the hearing narrows the judge’s options.
Serving Notice on the Other Parties
After filing, you must serve copies of the motion and any supporting documents on every party with a stake in the case. In a custody matter, that means the other parent and their attorney. In a guardianship case, it may include the proposed ward, existing guardians, and close family members.
Service methods depend on your jurisdiction’s rules. Common options are personal service (handing documents directly to the party), certified mail with return receipt, and electronic service for attorneys who have agreed to accept it. After serving, file a proof of service confirming that everyone received proper notice.
Courts set deadlines for service, giving the other parties time to review and respond before the hearing. Missing these deadlines can push the hearing back, so build in a buffer.
The Appointment Hearing
At the hearing, the judge decides whether appointing a GAL serves the interests of the person who needs protection. The judge reviews the motion, any declarations, and arguments from both sides.
Expect the other party to push back. Common objections are that a GAL is unnecessary because the child’s interests are already adequately represented, that the cost is prohibitive, or that the requesting party is using the motion as a litigation tactic. Concrete facts about why existing representation falls short are the most effective counter.
Judges sometimes want more input before deciding. A child psychologist, social worker, or school counselor may provide testimony or a written statement about the child’s needs. If you’ve already identified a specific GAL candidate, the judge may ask about that person’s qualifications and availability. In some jurisdictions, the court maintains its own roster of approved GALs and selects from that list rather than accepting party nominations.
Qualifications for who can serve vary by state. Some states require GALs to be licensed attorneys. Others allow non-attorneys with specialized training, social workers, mental health professionals, or CASA volunteers. Florida, for instance, requires either state program certification or active bar membership. Judges retain discretion to reject a proposed GAL who has a personal connection to a party, lacks relevant experience for the type of case, or has a track record raising concerns about impartiality.
If the judge grants the motion, the appointment order defines the GAL’s authority, the scope of the investigation, and often the initial payment arrangement. Read it carefully. It sets the boundaries for everything that follows.
Fees and Who Pays
Cost is the practical obstacle for most families, and it’s worth understanding before you file. Private GAL hourly rates typically range from around $50 to over $250 per hour, depending on the GAL’s qualifications, the local market, and whether the GAL is an attorney. A straightforward custody investigation might involve 10 to 30 hours of work. Complex cases with multiple children, abuse allegations, or extensive discovery can run much higher.
Courts usually address payment at the appointment stage. Common arrangements include splitting costs equally between the parties, assigning costs proportionally based on each party’s income, or ordering one party to pay the full amount. The judge examines each party’s financial ability before setting the allocation.
If you can’t afford a private GAL, several options may be available depending on your jurisdiction:
- Court-funded GAL programs pay GALs from public funds when the parties can’t afford the cost, though these programs typically cap the number of hours.
- CASA volunteers are trained advocates who serve as GALs at no cost to the parties, primarily in child abuse and neglect cases.
- Pro bono appointments allow courts to appoint attorneys to serve as GALs without charge when no suitable GAL from the regular roster is available.
- Sliding scale fees are used in some jurisdictions to adjust GAL compensation based on the parties’ financial circumstances.
What Happens After Appointment
A brief preview helps you set expectations with everyone involved. The GAL will typically interview the child (if old enough), both parents, teachers, therapists, doctors, and anyone else with meaningful contact. They review school records, medical records, prior court orders, and police reports. They visit homes. Both HIPAA and state privacy laws generally allow healthcare providers to release protected health information to a GAL acting under a valid court appointment order.
The GAL then prepares a written report with findings and recommendations, delivered to the judge and all parties typically ten to twenty days before the hearing, though exact deadlines vary. The GAL will also testify and be cross-examined. Recommendations carry significant weight, but they aren’t binding: the judge makes the final decision.
One thing to warn family members about before the GAL starts: nothing said to a GAL is privileged. A GAL is not anyone’s attorney. Anything said in an interview, including by the child, can appear in the report and become part of the record. Many states require GALs to give this warning explicitly before interviews, but assume it applies whether or not you receive one.
If the Court Denies Your Motion
A denial isn’t necessarily final. Judges sometimes deny GAL motions because the request was premature, the supporting evidence was thin, or the case didn’t yet appear complex enough to justify the appointment. Understanding the reason tells you what to do next.
If the denial was based on insufficient evidence, you can typically refile once you’ve gathered stronger documentation. A therapist’s letter, school records showing the child’s declining performance, or specific allegations with factual backup carry more weight than general assertions.
If the court decided a GAL isn’t needed yet, you may be able to renew the motion later if circumstances change. An amicable custody negotiation can escalate, and the judge may view an appointment differently once it does.
In rare cases a denial is appealable, particularly if a statute in your jurisdiction requires appointment in your type of case and the judge declined without adequate explanation. Interlocutory appeals of this kind are uncommon, and for most people the practical path is refiling with better evidence.
