What Does a Guardian Ad Litem Do in a Texas Child Custody Case?

 Posted on May 15, 2026 in Child Custody

When parents cannot agree on child custody, the court sometimes brings in a neutral third party to help sort things out. That person is called a guardian ad litem. If you are heading into a contested custody case in 2026, knowing what a guardian ad litem does and how much weight their findings carry can help you prepare. A Bexar County, TX child custody attorney at our firm can walk you through what to expect.

What Is a Guardian Ad Litem in a Texas Child Custody Case?

A guardian ad litem, sometimes called a GAL, is a person the court appoints to look out for your child's best interests. They do not represent you or the other parent. Their only job is to investigate what arrangement would be best for your child and report those findings to the judge.

Under Chapter 107 of the Texas Family Code, a guardian ad litem may investigate the child's circumstances, review records, talk to witnesses, and make recommendations to the court. While a GAL is not the same as your child's attorney, a judge may appoint one person to serve both roles in some cases.

When Does a Texas Family Court Appoint a Guardian Ad Litem?

A judge can appoint a GAL in any contested custody case where the child's welfare is at issue. This often happens when parents are in serious conflict, when there are allegations of abuse or neglect, or when the court believes neither parent is putting the child's needs first.

Either parent can also ask the judge to appoint a GAL. While many parents eventually work out custody issues, some conflicts continue for years after separation. A study published in the Journal of Marital and Family Therapy reported that about eight to 15 percent of co-parents remain locked in ongoing high-conflict disputes after divorce or separation. These are often the kinds of cases where a judge may appoint a GAL, because the court needs someone focused only on the child's best interests instead of the parents' ongoing disagreements. A GAL helps the judge cut through the conflict and get a clearer picture of what the child needs most.

What Does a Guardian Ad Litem Actually Investigate in Texas?

A GAL's investigation usually includes talking to both parents, the child, teachers, doctors, and anyone else who knows the child well. They may visit each parent's home, review school and medical records, and look at anything else that relates to the child's daily life and well-being.

The GAL is not there to take sides. If one parent tries to coach the child or make the other parent look bad, the GAL is trained to notice. They look for patterns: how each parent communicates with the child, how stable each home is, and whether either parent is putting their own interests first. 

How Does a Guardian Ad Litem's Report Affect a Texas Custody Decision?

After finishing the investigation, the GAL submits a written report to the court, typically at least 10 days before the final hearing. The GAL may also testify at trial. Judges take these reports seriously. When a judge is weighing two competing custody arguments, the GAL's findings often tip the scales, because their job is to give the court an honest picture of what the child needs without the noise from either side. The GAL's report is a recommendation, not a binding decision, but it carries real weight.

It is important to understand that a guardian ad litem is not the same as a licensed child custody evaluator, and the scope of the GAL's role depends on the court's appointment order. Knowing this limit can matter in how you prepare for the GAL's role in your case.

How Is a Guardian Ad Litem Different From an Attorney Ad Litem in Texas?

Parents often confuse these two roles. An attorney ad litem represents the child as a client and advocates for what the child says they want. A guardian ad litem advocates for what is in the child's best interest, even if that differs from what the child wants. Knowing which one the court has appointed matters, and your attorney can help you understand what it means for your case.
