New Hampshire Guardian Ad Litem in Custody Cases

A guardian ad litem (GAL) is a court-appointed investigator who evaluates a custody dispute and submits a best-interests recommendation to the judge. In New Hampshire, GAL appointments happen under RSA 461-A:16 and are reserved for high-conflict cases — not every custody case gets one. If a GAL is appointed in your case, their report often carries significant weight in the judge's final decision.

When Courts Appoint a GAL

Judges typically appoint a guardian ad litem when:

• Parental fitness is questioned — allegations of substance abuse, mental health concerns, neglect, or unsafe living conditions
• Domestic violence is alleged — the GAL investigates the impact on the child and each parent's ability to provide a safe environment
• Parents' accounts sharply conflict — when each parent tells a fundamentally different story about the child's daily life, school performance, or emotional well-being
• The child's preferences need independent assessment — particularly for older children whose stated wishes may be influenced by one parent

Either parent can request a GAL appointment, or the judge can order one independently. The appointment is discretionary — the judge decides whether the complexity and conflict level of the case justifies the cost and time of a GAL investigation.

What the GAL Does

The GAL conducts an independent investigation that typically includes:

Home visits. The GAL visits each parent's home to observe the child's living environment, the parent-child interaction, and the overall household stability. These visits are usually scheduled in advance, but the GAL may request an unannounced visit in cases involving safety concerns.

Interviews. The GAL interviews both parents, the child (age-appropriate), and relevant third parties — teachers, pediatricians, therapists, coaches, daycare providers, and extended family members who play a significant role in the child's life.

Record review. School records, medical records, therapy notes, police reports, and any prior court orders are reviewed to build a factual picture of the child's history and each parent's involvement.

Observation of exchanges. In high-conflict cases, the GAL may observe a custody exchange to assess the parents' ability to manage transitions without exposing the child to conflict.

The GAL Report and Recommendation

After completing the investigation, the GAL writes a detailed report with a recommendation on residential responsibility, decision-making authority, and the proposed parenting schedule. The report is filed with the court and shared with both parents.

The GAL's recommendation is not binding — the judge makes the final decision. But in practice, judges give substantial weight to GAL findings because the GAL has spent significantly more time investigating the family than the judge can during a hearing. Disagreeing with a GAL recommendation requires presenting compelling evidence that contradicts the GAL's findings.

Both parents have the right to cross-examine the GAL at trial. If you disagree with the recommendation, your attorney (or you, if pro se) can question the GAL's methodology, challenge factual errors, and present contrary evidence.

What It Costs

GAL services aren't free. The parents are charged for the GAL's time on a proportional sliding scale based on income. Costs vary significantly depending on the complexity of the case:

• A straightforward investigation with a few interviews and home visits might run $2,000-$5,000
• A complex case with multiple witnesses, expert consultations, and extensive record review can exceed $10,000

The court splits the cost between parents based on their relative incomes. If a parent is indigent, the court can order the state to cover their share, though this is rare.

How to Prepare for a GAL Investigation

Be cooperative. Refusing to participate, canceling home visits, or withholding records from the GAL creates an immediate negative impression. The GAL will note non-cooperation in their report.

Be honest. GALs are experienced investigators who will cross-reference your statements with records, third-party interviews, and the other parent's account. Exaggerations or fabrications get caught and undermine your credibility.

Maintain your normal routine. Don't rearrange your entire life for the home visit. The GAL wants to see your actual living environment and parenting routine, not a staged performance.

Document your involvement. Keep records of school meetings you've attended, medical appointments you've taken the child to, extracurricular activities you've supported, and your daily parenting activities. The GAL needs concrete evidence, not general claims about being a good parent.

Provide your witnesses. Give the GAL names and contact information for people who can speak to your parenting — the child's teacher, pediatrician, a neighbor who sees your daily routine. Don't assume the GAL will find them independently.
