How to Stay Calm in Court When You Think the Other Side Is Lying

You’re sitting a few feet away while the other parent tells the judge something you know isn’t true. Your heart pounds, your face gets hot, and every part of you wants to stand up and say so. Learning how to stay calm in court in that exact moment is one of the most useful skills a parent in a custody case can build, and it really is a skill, not a personality trait.

This guide covers what to do in the first few seconds, how to take notes that turn anger into evidence, when you’ll actually get your chance to respond, and how to prepare your nerves before the hearing so the worst claims don’t catch you off guard.

Why does staying calm matter so much in a custody hearing?

Because a custody case is partly about how each parent handles stress and conflict, and the courtroom is one of the few places the judge sees that firsthand. A judge may glance at you while the other parent is testifying. A muttered comment, a loud sigh or an interruption can undercut the very point you’re trying to make, especially if the other side is describing you as hot-tempered.

Calm doesn’t mean emotionless. Family court judges see tears, fear and frustration all the time. What matters is that you stay in control of what you say and do. You can feel furious and still look composed.

It also helps to remember whose job it is to decide who’s telling the truth. That’s the judge’s job, not yours. Your job is to give the judge what they need to decide: clear testimony and organized evidence, at the right time.

What should you do in the first ten seconds?

Give your body something to do besides react. The surge of adrenaline hits fast, and a simple physical routine buys you the seconds you need to think clearly.

1. Exhale slowly. Breathe in through your nose, then breathe out for longer than you breathed in. A long exhale is one of the simplest ways to settle a racing heart.
2. Plant your feet. Press both feet flat on the floor and notice the pressure. It pulls your attention out of your head.
3. Unclench. Relax your jaw, drop your shoulders and open your hands.
4. Pick up your pen. Writing is your release valve. It turns “That’s a lie!” into a note you can use later.
5. Keep your eyes on your notepad or the judge, not on the other parent.

How do you take notes you can actually use?

Write down only the claims that matter, with enough detail to find your evidence quickly. A simple three-part note works well: what was said, roughly when, and what you have that answers it.

Then put a star next to the claims that actually affect your child or the decision the judge has to make. Not every exaggeration is worth answering. If the other parent says you were rude at a birthday party three years ago, ask yourself whether correcting it helps the judge decide anything about your child’s schedule. Often the strongest move is to let minor digs go and spend your limited time on the points that matter.

Your notes also protect you from a common trap: forgetting a false claim by the time it’s your turn, then feeling the urge to blurt it out later at the wrong moment. Once it’s on paper, you can let it go until it’s useful.

Is it a lie, or a different version of events?

Before you label something a lie, even in your own head, ask whether it might be a different memory or a different way of seeing the same event. Two stressed parents can honestly remember an argument at an exchange very differently. That doesn’t make the other version correct, but it changes how you respond. “That’s not how I remember it, and here’s the text I sent that night” lands better than an accusation, and it keeps you credible if the judge sees the disagreement as an honest one. In court, you rarely need the word “lie” at all. Let your evidence show what’s accurate.

When do you get to respond to what they said?

Usually later, not in the moment. In most custody hearings, you’ll have your chance through one or more of these:

• Cross-examination, when you question the other parent after they testify. Our guide to cross-examining the other parent explains how to ask short, focused questions.
• Your own testimony, where you address the claims with your facts and exhibits.
• Rebuttal, if the judge allows it, to answer new points raised after you presented your side.
• A closing statement, if the judge allows one, to pull everything together.

Procedures vary, and some family court judges run hearings informally, asking each parent questions directly. If you’re not sure you’ll get a chance to respond, it’s appropriate to ask politely at a natural pause.

How do you answer a false claim without sounding angry?

Lead with the fact, point to the evidence, and stop. Let the judge draw the conclusion that the other parent’s statement was inaccurate. You don’t need to say it for them.

Notice what the credible versions leave out: name-calling, sarcasm, guesses about the other parent’s motives, and speeches. One sentence of fact, one exhibit. Our guide on how to testify in family court goes deeper on giving clear, specific answers under oath.

How do you prepare your nerves before the hearing?

Expose yourself to the hardest moments ahead of time, so you hear the claims for the first time at your kitchen table, not in the courtroom.

1. List the five worst things they might say. Look at past messages, court filings and old arguments. You probably already know their main themes.
2. Write a calm one-sentence answer for each. Attach the exhibit or fact that supports it.
3. Hear them out loud. Ask a trusted friend to read the claims to you in an accusing tone, or use a role-play tool like Mediation Coach, which can play the other parent so you can practice responding evenly.
4. Practice your physical routine while you listen, until it starts to feel automatic.
5. Protect the basics. Sleep, eat something, and go easy on caffeine the morning of the hearing.

If the other side has a lawyer or the stakes feel especially high, a consultation with a licensed attorney where you live can help you understand the procedure your court is likely to follow. Simply knowing what comes next makes the day far less unnerving.

What if you lose your composure anyway?

Recover quickly and move on. One moment of emotion doesn’t define your case; how you handle the next minute matters more.

• If you interrupted, stop and say, “I apologize, Your Honor.”
• If you’re crying or shaking, it’s generally fine to ask, “Your Honor, may I have a moment?” Take a sip of water and continue.
• If you need a longer break, ask politely. Short recesses are a normal part of court.
• Go back to your notes and your next point. Don’t keep apologizing or explaining the outburst.

If what you’re feeling is fear rather than anger, because the other parent has been abusive or threatening, tell the bailiff or court staff. Some courthouses can arrange separate waiting areas or an escort to your car, and victim advocates may be available. Real safety concerns deserve to be taken seriously. If you’re in danger, call 911.
