Guardian ad Litem Investigations

If a GAL has been appointed to your custody case — or is about to be — understanding what the investigation involves, what the GAL is looking for, how to navigate the process, and how their report affects your case can make a significant difference in how you prepare and respond.

Custody modifications & disputes involving serious allegations, high conflict, or complex circumstances are the most common triggers for GAL appointment. Understanding the process reduces anxiety and helps you focus on what actually matters.

What a Guardian ad Litem Is

A guardian ad litem is a court-appointed investigator whose sole client is the child — not either parent. Their job is to conduct an independent investigation and submit a written report to the judge with recommendations on parenting arrangements, time-sharing, and parental responsibility that they believe serve the child’s best interests.

A GAL is not the same as a forensic custody evaluator. A custody evaluator is typically a licensed psychologist who conducts formal psychological testing of both parents and the child. A GAL investigates through interviews, home visits, and records review — without administering clinical assessments. In some states GALs are licensed attorneys; in others, trained volunteers. Florida operates a statewide volunteer-based Florida Guardian ad Litem Program under § 61.401–61.404.

What the Investigation Involves

Home Visits and Parent Interviews

The GAL will visit each parent’s home — often with minimal notice — and interview each parent separately. They are observing the physical environment, the child’s living conditions, how each parent interacts with the child, and how each parent speaks about the other. How you discuss the other parent during these interviews matters significantly.

The Child Interview

The GAL will interview your child, almost always without either parent present. The interview is age-appropriate and designed to assess the child’s relationship with each parent, their adjustment to each home, any fears or concerns they express, and whether their views appear to be genuinely their own or coached.

You are permitted to prepare your child — explaining who the GAL is and that it is safe to speak honestly. What you cannot do is tell your child what to say, rehearse specific answers, or express negative views about the other parent in advance. Courts treat coaching as a serious finding against the coaching parent.

Collateral Sources

Most parents are surprised by how broadly the GAL investigates. Beyond home visits and interviews, GALs routinely contact teachers, school counselors, pediatricians, therapists, coaches, and childcare providers. They review school records, medical records, mental health records, prior CPS or DCF reports, police reports, and prior court filings. If substance abuse or mental health concerns are alleged, the GAL may refer a parent for drug testing or a psychological evaluation.

The GAL Report

The GAL submits a written report to the court — typically before the evidentiary hearing — that summarizes their findings and makes specific recommendations. Both parties receive a copy.

The report is influential but not binding. Judges give GAL recommendations significant weight because the GAL has had direct contact with the child and both households in a way the judge has not. However, a judge can depart from those recommendations if the evidence at hearing supports a different conclusion.

Challenging the GAL Report

If you disagree with the GAL’s findings, you have the right to challenge them at the hearing. The GAL can be called as a witness and cross-examined on the basis for their conclusions, who they interviewed, what records they reviewed, and whether the investigation was conducted thoroughly and impartially.

If you believe the GAL has a genuine conflict of interest or conducted a demonstrably one-sided investigation, you can file a motion to replace them — but courts set a high bar for removal. Disagreement with their conclusions alone is not sufficient grounds.

What Helps and What Hurts

What consistently helps: cooperating fully and transparently with the GAL, keeping the child’s environment stable and age-appropriate, maintaining a respectful tone about the other parent, and ensuring the GAL can easily reach your collateral contacts.

What consistently hurts: speaking negatively about the other parent in front of the child, limiting the GAL’s access to records or witnesses, coaching the child, and failing to disclose information the GAL will likely uncover independently.

Costs

GAL fees vary significantly. In Florida, the statewide volunteer GAL Program assigns trained volunteers at no cost to the parties. In states using paid attorney GALs, fees are allocated by the court — often split between the parties, though the allocation can be adjusted based on each party’s financial circumstances or conduct during the proceedings.
