A guardian ad litem (GAL) is a person a court appoints in a specific case to look into a child’s situation and tell the judge what arrangement serves the child’s best interests. In custody disputes, the judge usually appoints one when the parents cannot agree. The GAL then investigates both households, writes a report, and the judge weighs that report when deciding. The GAL does not decide the case, and the GAL does not work for either parent.

If you have just been told a GAL is coming, the most useful thing you can do is get your records in order and learn what the process looks like. This guide covers both.

TL;DR

  • A GAL is appointed for one case to investigate and recommend what is best for the child. The judge, not the GAL, makes the final decision.
  • Courts most often appoint a GAL when parents cannot agree on a parenting plan or when there are concerns about the child’s well-being.
  • A GAL typically interviews both parents, sees the child with each parent, and reviews school, medical and court records.
  • Cooperation, honesty and organized, factual records make the GAL’s work easier and your position clearer.
  • Rules on appointment, cost and challenges differ by state, so check your own court’s guidance and speak with a family law attorney.

What a guardian ad litem is in a custody case

The term is Latin for “guardian for the lawsuit.” Cornell’s Legal Information Institute explains that a guardian ad litem is appointed for a specific case to protect the interests of a person who cannot protect themself, most often a minor. Custody, support, divorce, adoption and visitation disputes are common settings.

In practice, the GAL acts as the court’s fact-finder. Illinois Legal Aid Online describes the GAL as the judge’s “eyes and ears” in the case. Minnesota’s legal help organizations add that the GAL investigates independently and tells the court what is best for the child, rather than working for court services or child protection.

Who serves as a GAL varies. Some are attorneys, some are trained professionals, and in some places they are volunteers. Your appointment order and your state’s court rules set the details.

When a court appoints a GAL

There is no single national rule. Each state sets its own standards, but the pattern is similar.

  • Parents cannot agree. New Hampshire’s Judicial Branch says a GAL is typically appointed when parents cannot agree on a parenting plan, and that the appointment order identifies the disputed issues to investigate.
  • A judge needs more information. In Washington, when a judge must decide on a parenting plan, the court may appoint a GAL to investigate both households and recommend a plan in the children’s best interests.
  • The law requires one in some situations. Wisconsin courts must appoint a GAL when there are concerns about the child’s well-being or parents have not agreed on custody and placement. The same source notes a GAL may be unnecessary when an existing arrangement stays the same and proposed changes would not significantly affect parenting time.

The appointment order matters. It can limit the GAL’s job to certain questions. Washington’s guidance says the court may narrow an investigation to issues such as domestic violence or substance abuse. Read your order closely and ask your attorney what it covers.

Whom the GAL represents

This is where parents are often confused. The GAL does not represent you, and does not represent the other parent. The GAL also does not simply carry out what the child wants.

Wisconsin Law Help explains that the GAL represents the child’s best interests, not necessarily the child’s wishes, and that the child is not the GAL’s client. A child’s preference can matter, but the GAL’s role is to assess what is best, not to relay a desired outcome.

Some states also have a separate role. Illinois Legal Aid Online separates a GAL from an attorney for the child. The GAL recommends what is in the child’s best interests. An attorney for the child presents the child’s wishes and owes the usual attorney duties of loyalty and confidentiality. Check which role your court has assigned, because it changes what you can expect from the conversation.

What a GAL investigates

The scope depends on the order and state rules, but the investigation usually looks like a structured review of your family’s life.

Washington’s guidance says a GAL can review criminal, court and other important records. The GAL may interview the parents, may speak with friends, family and professionals involved with the family, and can observe parents and children at home or in another setting (see the Washington guide).

Ohio’s Supreme Court publishes a judicial guide that is more detailed. Subject to the appointment order and Ohio rules, GALs are expected to become informed about the case, observe the child with each parent or custodian, and interview the child when developmentally appropriate. They are also expected to visit the child’s residence, learn the child’s wishes and concerns, and contact school, medical, mental-health, child-protection and court personnel. The guide also lets a GAL request psychological, mental-health or substance-abuse evaluations when they would help the court.

South Carolina Legal Services lists a similar set of tasks: school and medical record review, interviews with parents, caregivers, school officials and law enforcement, criminal-history review, and written court reports.

Contact with the child is not one-size-fits-all. Indiana’s official guide says the GAL must have reasonable in-person contact with the child, and what is reasonable depends on age, development, health and the circumstances of the case, including for infants and nonverbal children.

The best interests standard the GAL applies

Every state decides custody on the child’s best interests, but each lists its own factors. A few examples show the range.

State What the source says
Indiana The court decides on the child’s best interests with no presumption favoring either parent, considering factors such as age, wishes of the parents and child, relationships with parents and siblings, adjustment to home, school and community, health, domestic or family violence, and de facto caregiving.
Michigan Best interests are the totality of listed factors, including emotional ties, parenting capacity, stability, moral fitness, the child’s record at home, school and in the community, and each parent’s support of the other parent-child relationship.
New York A court decision in Matter of Yishak v. Ashera says the overriding consideration is the child’s best interests, judged on the totality of circumstances, including stability, the child’s wishes, home environment and the effect on the child’s relationship with the other parent.

Two points follow. First, a GAL is looking for patterns that fit these factors: who handles school, medical care and daily routines, how stable each home is, and whether each parent supports the child’s bond with the other. Second, your records are most useful when they speak to those factors in plain, factual terms.

If you want state-specific context, our guides on custody in Indiana, Minnesota, Arizona and Colorado walk through how courts there approach parenting time.

How to prepare for a GAL

The GAL will form an impression from your cooperation, your tone and your documentation. Indiana’s official family guide offers practical advice that applies broadly:

  • Respond promptly to interviews and home visits.
  • Be honest and communicate respectfully and calmly.
  • Raise child-safety concerns when you have them.
  • Keep the focus on the children.
  • Let the GAL speak with your child privately, without interruption.
  • Ask questions when you do not understand something, and respect the GAL’s time.
  • Give the GAL witness information and relevant medical, therapy, criminal, police and school records.

That guidance is available in the Indiana guide to working with a GAL. Minnesota’s legal help organizations add a caution worth remembering: a GAL report can help or hurt a parent’s case, so cooperation and keeping the child’s best interests first matter.

Build a record the GAL can use

A GAL has limited time and many sources. Records that are dated, specific and neutral are easier to rely on than a long emotional account. A workable approach:

  1. Start a dated history. Log each exchange, missed or changed visit, school event, medical appointment and notable conversation on the day it happens, while details are fresh.
  2. Separate fact from interpretation. Write what happened, what was said, and who was there. Leave out guesses about motives. “The handover was 40 minutes late; I waited at the school entrance” is stronger than “he does this on purpose.”
  3. Organize messages by topic and date. Schedules, medical decisions, school issues and money are easier to review when they are not one long thread.
  4. Track expenses. Keep receipts and shared costs for childcare, medical care and school in one place.
  5. List firsthand witnesses. Name people who saw events themselves, such as teachers, coaches or caregivers, and note how to reach them.
  6. Keep originals. Do not edit or crop screenshots, and preserve the context around anything you share.
  7. Describe effects on the child. Note specific changes you observed, such as sleep, school performance or mood, without diagnosing.

Our custody evidence checklist lays out what to gather, and the record router helps you decide what is worth logging. If you plan to meet an attorney before the GAL’s first interview, the lawyer meeting preparation pack turns your notes into something you can bring. For a broader view of how everyday behavior can later matter in a case, read what can be used against you in a custody battle.

What to avoid

Keep your child out of the middle. Do not coach answers, quiz your child after a GAL visit, or speak badly about the other parent in front of the GAL. Those habits tend to appear in the report. Do not hand over a huge, unsorted pile either. Pick the records that relate to the disputed issues named in the order.

A simple way to keep records with Casewell

Parents with a hard-to-reach co-parent often tell us the same thing: the facts are in their head, scattered across texts, and a GAL meeting is days away. Casewell is a digital custody journal built for this. You log exchanges, messages, expenses and parenting time in one place, and prompts after each exchange or handover help you capture the details while they are fresh. The timeline updates in real time.

When you need to share records, Casewell creates clear, filterable, indexed PDFs that you can export for legal review. If you want an entry to read more neutrally, optional AI assistance can suggest a rewrite, and you approve the wording. Records are stored encrypted on your device, and we do not keep copies on company servers.

Casewell Premium is $2.99 per week or $49.99 per year, and there is a free trial period. If you need a structured chronology for court, our court timeline service starts from ÂŁ29 one-off. You can see how the journal works on our US features page, or look at court-ready co-parenting records and PDF reports.

Our perspective

Most parents meet a GAL after months of conflict, and by then the hardest part is not the law. It is remembering. Details from three months ago blur, and the other parent’s version is often louder than yours.

We built Casewell around a simple belief: a calm, dated, neutral record helps everyone, including the child. A GAL does not need your anger. A GAL needs to see what a normal week looks like in your home, who shows up, and how you handle disagreements.

That is why we designed the journal to prompt you right after a handover, when the facts are clear, and why our optional AI-assisted rewriting is meant to help you phrase entries in neutral language that you review and approve. It is also why your records stay encrypted on your device. Your parenting history is sensitive, and you should decide who sees it and when.

When you can export a clear, indexed PDF of exactly the period the GAL asks about, you spend less time hunting through your phone and more time on the thing the GAL cares about: your child.

What happens to the GAL’s report

The report is the GAL’s main product, and it can carry weight, but it is not the verdict.

New Hampshire’s Judicial Branch says the GAL usually prepares a written report recommending a resolution of custody and visitation issues that the GAL considers to be in the children’s best interests. Indiana’s guide says the report usually describes the investigation, recommendations and reasoning, and that a party may respond in writing or present evidence at a hearing. The court, not the GAL, determines the outcome.

Massachusetts Legal Services explains that the judge reviews a GAL report at a hearing or considers it as evidence at trial together with the GAL’s testimony. The report may present facts, analyze them and make recommendations when the judge asks for them (Massachusetts guide).

Courts are not bound to follow the recommendation. In Borden v. Borden, the Mississippi Supreme Court held that a court is not bound by a GAL recommendation. Where the appointment was mandatory and the court rejects the recommendation, the court must summarize it and state its reasons in its findings. That is one state’s rule, so ask your attorney how your state treats it.

What happens to the GAL's report

If you disagree with the GAL

You are not without options, but the path is procedural and calm beats confrontational.

In Wisconsin, a parent may object to inaccuracies in the GAL’s report or allege misconduct, and the court considers the report and the parents’ responses when deciding custody, placement or visitation (Wisconsin Law Help). In Illinois, a GAL may be called by the judge to testify, and parties may call the GAL as a witness or cross-examine the GAL, because the GAL functions as the judge’s fact-finder (Illinois Legal Aid Online).

This is where dated records earn their value. If the report gets a date, an event or a sequence wrong, a timestamped entry made at the time is far more persuasive than memory. Raise specific factual errors through the process your court sets, ideally with your attorney. A general complaint that the GAL was unfair is much harder to act on.

Who pays for a GAL

Cost rules differ by state and by court. In New Hampshire, the appointment order specifies how much each party must pay, unless the parties are indigent (New Hampshire Judicial Branch). Elsewhere, the court may split the fee between parents, assign it to one parent, or use a volunteer program. Look at your appointment order or ask the clerk’s office how fees are set in your county.

FAQ

Is a guardian ad litem on my side?

No. The GAL works for the child’s best interests and acts as the court’s fact-finder, not as an advocate for either parent. Your attorney represents you. Treat the GAL as a neutral professional who is forming an independent view.

Does the judge have to follow the GAL’s recommendation?

Generally no. The court makes the final decision, and the recommendation is one piece of evidence. Some states require judges to explain on the record why they reject a GAL’s recommendation in certain appointments, as in Mississippi. Ask your attorney what applies in your state.

What records should I give a guardian ad litem?

Start with what the appointment order covers and what the GAL asks for. Indiana’s guide mentions medical, therapy, criminal, police and school records, plus witness information. Organize them by topic and date, and keep originals so the GAL can see the full context.

Will the GAL talk to my child?

Usually yes, when the child’s age and development allow. The GAL commonly observes the child with each parent and may interview the child privately. Do not coach your child. Let the conversation happen without interruption, as official guidance advises.

Can I ask the court for a GAL?

In many states a parent can ask the court to appoint one, and a judge can appoint one without a request. Whether to ask depends on your facts, cost and local practice, so talk to a family law attorney or your court’s self-help center first.
