When a custody case gets contested enough, the court may appoint someone whose only job is the child’s side of things. That person is often called an ad litem — either an attorney ad litem or a guardian ad litem. The two titles sound interchangeable. They are not. One acts as the child’s lawyer; the other investigates and tells the court what would serve the child’s best interests. Knowing which one your case has changes how you should work with them.
This guide explains both roles, how they differ, and what to expect.

What “Ad Litem” Means
The phrase is Latin: ad litem means “for the lawsuit.” An ad litem is someone the court appoints to act for a particular person — here, a child — but only within that case. The appointment starts when the judge signs the order and ends when the case closes.
Children cannot represent themselves in court, and in a contested custody fight each parent is presenting their own version of events. The ad litem exists to make sure the child’s interests are not lost in the gap between two competing adults. According to the Legal Information Institute at Cornell Law School, courts appoint these representatives precisely because the child needs a voice independent of the parties.
What that voice does — advocate or investigate — depends on which kind of ad litem the court appoints.
What an Attorney Ad Litem Does
An attorney ad litem is a licensed lawyer appointed to represent the child as a client. The key word is represent. This attorney owes the child many of the same duties a family lawyer owes an adult client: confidentiality, loyalty, and advocacy for what the client wants.
In practice, an attorney ad litem:
- Meets privately with the child
- Advocates for the child’s stated wishes, within reason
- Files motions, examines witnesses, and argues in court on the child’s behalf
- Functions as a full party’s lawyer would, but for the child
The distinction that matters: an attorney ad litem generally advances what the child wants, not what the attorney personally thinks is best. With older children especially, this gives the child a genuine voice in proceedings that will reshape their daily life. State rules vary on how this works when a child is too young to express a considered preference.
What a Guardian Ad Litem Does
A guardian ad litem, usually shortened to GAL, is appointed to investigate and report on the child’s best interests. A GAL is not necessarily the child’s lawyer — in some states the role is filled by attorneys, in others by trained volunteers or mental-health professionals.
The GAL’s job is investigation, not advocacy for the child’s wishes. A typical GAL will:
- Interview both parents, the child, and often teachers, doctors, and relatives
- Review records — school, medical, and any custody documentation the parents provide
- Visit each parent’s home
- Sometimes observe parent-child interaction
- Submit a written report and recommendation to the judge
The pivotal difference: a GAL tells the court what they believe is best for the child, even when that differs from what the child says they want. A teenager might tell a GAL they want to live with the more permissive parent; the GAL may still recommend otherwise if the evidence points there. Judges give these recommendations real weight, which is why a GAL’s involvement can shape the outcome of a contested custody case.
Attorney Ad Litem vs. Guardian Ad Litem
The two roles line up cleanly once you see them side by side.
| Attorney Ad Litem | Guardian Ad Litem (GAL) | |
|---|---|---|
| Core job | Represents the child as a client | Investigates the child’s best interests |
| Advocates for | What the child wants | What is best for the child |
| Must be a lawyer | Yes | Not always (varies by state) |
| Main output | Advocacy in court | Written report and recommendation |
| Confidentiality | Owes the child attorney-client duties | Generally reports findings to the court |
| Best analogy | The child’s lawyer | The court’s investigator for the child |
One caution: states use these titles inconsistently. In some jurisdictions a single appointee performs both functions, and a few states fold everything under one label. Always confirm with the appointment order — it defines the specific duties — rather than assuming from the title alone.
Who Pays and How One Is Appointed
Appointment. A judge appoints an ad litem, either on a parent’s motion or on the court’s own initiative. It commonly happens in cases involving serious disagreement, allegations of abuse or neglect, relocation fights, or concerns about a parent’s fitness. Where safety is in question, the appointment may sit alongside protective measures like supervised visitation.
Cost. In private custody cases, the parents usually pay the ad litem’s fees — frequently split between them, with the exact division set by the court based on each parent’s resources. In abuse and neglect cases brought by the state, the role is often filled by a publicly funded attorney or a trained volunteer at no cost to the parents. Ask early how fees will be handled, because in a contested private case they add a real line item to the cost of the dispute.
How to Work With an Ad Litem
How you treat the ad litem matters, because their impression of you reaches the judge. A few rules hold regardless of which type is appointed:
- Be cooperative and prompt. Return calls, show up to scheduled visits, and provide records when asked. Stonewalling reads as something to hide.
- Be honest. Ad litems compare what each parent says against the records and the other parent’s account. A claim that does not hold up damages your credibility on everything else.
- Keep the focus on the child. An ad litem is evaluating you as a parent, not refereeing your grievances with the other adult. Steer every conversation back to the child’s needs and routine.
- Stay organized. A clear, dated record of involvement in the child’s life — appointments, school events, daily care — gives the ad litem concrete facts to work with.
- Do not coach the child. Ad litems are trained to spot a rehearsed child, and nothing undermines a parent faster.
Treat the ad litem as a neutral professional doing a job, because that is exactly what they are.
Frequently Asked Questions
What does ad litem mean?
“Ad litem” is Latin for “for the lawsuit.” An ad litem is a person a court appoints to act on behalf of someone — usually a child — but only within that specific case. The appointment begins when the judge orders it and ends when the case concludes.
What is the difference between an attorney ad litem and a guardian ad litem?
An attorney ad litem represents the child as a client and advocates for what the child wants. A guardian ad litem investigates and reports to the court on what would serve the child’s best interests, even if that differs from the child’s stated wishes. The attorney ad litem acts as the child’s lawyer; the guardian ad litem acts as the court’s investigator for the child.
Is a guardian ad litem always a lawyer?
No. Whether a guardian ad litem must be an attorney varies by state. In some jurisdictions the role is filled by lawyers, while in others it is performed by trained volunteers or mental-health professionals. The appointment order and state rules define who can serve and what they must do.
Who pays for an ad litem?
In private custody cases, the parents usually pay the ad litem’s fees, often split between them according to each parent’s resources as the court directs. In abuse or neglect cases brought by the state, the role is frequently filled by a publicly funded attorney or trained volunteer at no cost to the parents.
Can a guardian ad litem recommend against what the child wants?
Yes. A guardian ad litem’s duty is to the child’s best interests, not the child’s stated preference. If the evidence points one way and the child wants another, the GAL can recommend what they believe serves the child, and judges give those recommendations significant weight.
How should I act around the ad litem?
Be cooperative, honest, and organized, and keep every conversation focused on the child rather than on conflict with the other parent. Return calls promptly, attend scheduled visits, provide records when asked, and never coach the child. The ad litem’s impression of you reaches the judge.
