The short version of what not to say to a Guardian ad Litem: anything that trashes the other parent, anything you can’t back up, anything that contradicts what the records show, and anything a judge would not want to hear. A GAL is appointed by the court to investigate your family and recommend a custody arrangement, and everything you tell them can end up in a written report and in open-court testimony. Judges are not required to follow those recommendations, but they lean on them heavily.
Before going through the specific mistakes, understand the ground rule that makes them mistakes at all.
Nothing You Say Is Confidential
A GAL is not your therapist, your friend, or your attorney. They function as an arm of the court and are expected to testify about everything they learn during their investigation without needing anyone’s permission. Every conversation, every offhand remark, every frustrated vent about your ex can appear in the report and be discussed in court.
That does not mean you should be guarded to the point of seeming evasive. It means treating every interaction the way you would treat testimony: honest, relevant, and measured. If you would not want a judge to hear it, do not say it to the GAL.
Don’t Badmouth the Other Parent
This is where most parents hurt themselves without realizing it. Speaking negatively about the other parent feels natural during a custody dispute, but a GAL hears it very differently than a sympathetic friend would. Courts across the country evaluate each parent’s willingness to support the child’s relationship with the other parent, and a GAL is specifically watching for signs that one parent is poisoning that relationship.
There is a meaningful difference between raising a legitimate safety concern and running a campaign of complaints about your ex’s character. If the other parent has a documented substance abuse problem that affects the child, say so clearly and provide evidence. Launching into how your ex is lazy, selfish, or a terrible person signals to the GAL that you may be the one creating conflict. GALs are trained to recognize parental alienation, where one parent systematically turns the child against the other. Even mild versions, like sarcastic comments during the interview, can raise red flags.
When a GAL suspects alienation, they may recommend reducing the alienating parent’s custody time, requiring supervised visitation, or shifting primary custody to the other parent. Tearing down your ex in front of the GAL is one of the most counterproductive things you can do.
Don’t Make Accusations You Can’t Support
Accusing the other parent of abuse, neglect, drug use, or other serious misconduct without evidence almost always backfires. A GAL evaluates claims based on what can be verified, not on how passionately you believe them. When you make a serious allegation and cannot point to police reports, medical records, photographs, or credible witnesses, the GAL does not just set it aside. They start questioning your judgment and your motives.
False allegations are particularly damaging because they suggest you are willing to weaponize the legal process against the other parent. If you have genuine concerns about your child’s safety, document them before you raise them. Bring the evidence to the GAL and let it speak for itself. A single well-documented concern carries far more weight than a list of vague accusations.
Don’t Lie, and Don’t Contradict Yourself
GALs do not take your word for things. They interview both parents, talk to teachers and doctors, review school and medical records, and sometimes speak with neighbors or extended family. If you say you have been the primary caregiver and the school records show the other parent handles every pickup and parent-teacher conference, that inconsistency will land in the report.
The same goes for contradicting yourself across conversations. Describe your work schedule one way in the first meeting and differently in the second, and the GAL notices. Inconsistencies do not just weaken the specific claim that turns out false. They cast doubt on everything else you have said. Once a GAL decides you are not a reliable source, rebuilding that credibility is extremely difficult. Honesty, even about things that do not make you look great, is the better strategy.
Don’t Get Hostile or Threatening
Raising your voice, making threats, or being verbally aggressive toward the GAL is one of the fastest ways to damage your case. The GAL is evaluating how you handle conflict, and if you cannot manage a civil conversation with a professional whose job is to help your child, the GAL will reasonably question how you handle disagreements at home. Courts view conflict management as a critical factor in custody decisions.
Beyond the custody implications, threatening a court-appointed officer can result in contempt charges, which carry fines or even jail time depending on your jurisdiction. If the GAL reports feeling unsafe during an interaction with you, that observation goes directly to the judge. Even if you believe the GAL is biased or unfair, expressing that through hostility only confirms the worst assumptions about your temperament.
GALs in many states are also mandatory reporters. If something you say or do during the investigation leads them to suspect child abuse or neglect, they may be legally required to report it to child protective services or law enforcement. Losing your temper in a way that raises concerns about how you treat your child can trigger consequences well beyond the custody case itself.
Don’t Coach Your Child
Telling your child what to say to the GAL is one of the most scrutinized behaviors in custody evaluations. GALs interview children specifically to hear their genuine perspective, and attempts to script those answers undermine the entire process. Courts treat coaching as a serious red flag that can shift custody away from the coaching parent.
GALs are experienced at spotting coached responses. Common giveaways:
- Adult vocabulary from a small child. A seven-year-old who says “my father is emotionally unavailable” is clearly repeating a line. Children describe things in their own words.
- Suspiciously detailed accusations. When a young child gives a highly specific, realistic-sounding account of misconduct, it often sounds more like an adult composed it. The more polished the story, the more suspicious it becomes.
- Rehearsed delivery. Coached children often sound like they are reciting rather than recalling. Answers come too quickly and too perfectly.
- Unusual gifts or rewards. A sudden spike in high-value gifts around the time of GAL interviews can suggest a parent is bribing the child for cooperation.
GALs also observe parent-child interactions in person, watching for controlling behavior or signs that the child is performing for the parent’s benefit rather than acting naturally. If a GAL concludes coaching occurred, the report will say so explicitly, and judges take that finding very seriously.
Don’t Waste the Interview on Petty Complaints
A GAL’s job is to assess specific factors that affect your child’s wellbeing: the stability of each home, each parent’s physical and mental health, the quality of the parent-child relationship, each parent’s ability to cooperate, and any history of violence or substance abuse. Those are the issues that drive custody recommendations.
Spending your time complaining that your ex lets the kids stay up too late, feeds them too much fast food, or has an annoying new partner wastes a limited opportunity to address what actually matters. It also makes you look like someone who cannot distinguish between real concerns and petty grievances. GALs see this pattern constantly, and it almost always works against the complaining parent. Before meeting with the GAL, organize your thoughts around the factors courts actually weigh. Everything else is noise that dilutes your credible points.
Don’t Dismiss the Process or Stonewall Requests
Dismissing the GAL’s role, complaining about the court system, or expressing contempt for the process works against you in several ways. The GAL is an extension of the court, and treating them dismissively signals that you may not cooperate with court orders down the road. Judges care deeply about which parent is more likely to follow custody arrangements, and a parent who openly disrespects the process gives the impression they will not. Subtler forms count too: showing up late to scheduled meetings, being sarcastic or condescending, or making comments about how the system is rigged.
The same principle applies to information requests. GALs typically need access to documents and information to complete their investigation: financial records, medical reports, school records, and access to your home. Refusing to provide what they ask for, or dragging your feet until deadlines pass, sends a clear message that you have something to hide, whether or not that is actually true.
Courts have inherent authority to enforce compliance. If you refuse to cooperate, the judge can compel you through a court order, and continued resistance can result in contempt charges, fines, or an adverse inference in the custody decision. An adverse inference means the court assumes the missing information would have been unfavorable to you. If a GAL asks for something you believe is irrelevant or overly intrusive, raise that concern with your attorney rather than refusing outright. Your lawyer can file a motion or negotiate the scope of the request through proper channels.
What You Post Online Counts Too
What you post during a custody case is fair game for the GAL’s investigation. Photos of heavy drinking, angry rants about your ex, evidence of expensive purchases while claiming financial hardship, or anything that contradicts what you told the GAL in person can appear in the report. Social media posts have been used in custody cases to demonstrate poor judgment, dishonesty, and parenting concerns.
Assume the GAL will see everything you post. Adjust your privacy settings, but do not rely on them. Screenshots exist. Friends of friends talk. If a post would look bad to a judge, do not publish it.
If the Report Comes Back Badly
A GAL’s report is not automatically accepted as fact by the court. You have the right to review it, and your attorney can challenge it. The most direct method is cross-examining the GAL under oath about their investigative methods, factual findings, and conclusions. If the GAL relied on incomplete information or drew unsupported conclusions, cross-examination is where those weaknesses come out. You can also present contradictory evidence: school records, medical documents, or testimony from witnesses with direct knowledge of your parenting. In some jurisdictions, your attorney can file a motion to strike all or part of the report, or request that the GAL be removed and replaced.
Work through your attorney and the court process rather than arguing directly with the GAL. Confronting the GAL about their findings outside of court accomplishes nothing and may make things worse.
