| Defendants must follow strict courtroom rules covering conduct, dress, communication, and respect toward the judge, and violating them can affect how a judge or jury perceives the case. Every interaction, from addressing the court to speaking with an attorney, follows a set protocol designed to keep proceedings orderly and fair. |
Show up to court looking sloppy, talk back to the judge, or forget who’s really in charge of that room, and you’ve already hurt your case before your attorney says a word. The rules of the courtroom aren’t suggestions. Break them, and you risk turning a judge or jury against you before the facts are even on the table.
Here’s what you need to know before you ever set foot in front of a judge:
- Dress professionally and conservatively
- Arrive early and never be late
- Stand when the judge enters or speaks to you
- Address the judge as “Your Honor”
- Never interrupt the judge, prosecutor, or witnesses
- Keep emotional reactions in check
- Turn off and put away phones and electronic devices
- Speak only when instructed and only to your attorney
- Follow your attorney’s lead on when to talk and when to stay silent
Facing a courtroom is intimidating, especially when your future is on the line. Mark Thiessen — backed by 160+ Not Guilty verdicts and thousands of dismissals — breaks down the rules of the courtroom every defendant should know, from proper conduct and dress to how and when to speak, so you know exactly what to expect.
Rule #1: Dress professionally and conservatively
Defendants should dress in clean, conservative clothing, like a suit, dress shirt, or modest business attire, and avoid anything flashy, revealing, or covered in logos or slogans. What you wear sends a message to the judge and jury before you ever open your mouth, and that message should be built from respect. Courtroom etiquette starts the moment you walk through the door, and your appearance is the first impression you make.
What to wear:
- Suit or dress pants with a collared shirt
- Conservative dresses or blouses with slacks or skirts
- Closed-toe shoes, nothing flashy
What to avoid:
- T-shirts, tank tops, or ripped clothing
- Hats or sunglasses
- Political, religious, or controversial slogans
- Excessive jewelry or strong cologne/perfume
Judges see hundreds of defendants a year, and they notice who took the process seriously and who didn’t. Don’t give the court a reason to assume the worst about you before your case even starts.
Rule #2: Arrive early and never be late
Defendants should arrive at least 15 to 30 minutes before their scheduled court time to allow for security lines, parking, and finding the right courtroom. Showing up late doesn’t just look bad; it can result in a warrant being issued for your arrest. Houston courts run on tight dockets, and judges have zero patience for defendants who can’t be bothered to show up on time.
Here’s why it matters:
- Being late can be treated as a failure to appear.
- A failure to appear can result in a new warrant, on top of your existing charges.
- Judges remember who respects their time and who doesn’t.
Get there early, find your courtroom, and check in with your attorney before your case is called. There’s no version of “I got stuck in traffic” that a judge wants to hear.

Rule #3: Stand when the judge enters or speaks to you
Defendants must stand when the judge enters or exits the courtroom, and typically when the judge speaks directly to them. This is one of the most basic, non-negotiable rules of courtroom etiquette, and skipping it reads as disrespect for the court itself. When the bailiff calls “all rise for the judge,” you stand, no exceptions.
When to stand in court:
- When the judge enters or leaves the courtroom
- When the judge addresses you directly
- When instructed by the bailiff or your attorney
This one takes zero legal knowledge to get right. Stand up, stay quiet, and follow the room’s lead.
Rule #4: Address the judge as “Your Honor”
Defendants should always refer to the judge as “Your Honor,” never by name, “sir,” “ma’am,” or anything else. It’s a small phrase, but it carries weight, and getting it wrong can make you look careless in front of the very person deciding your fate. Save the casual talk for outside the courthouse.
- Correct: “Yes, Your Honor” or “No, Your Honor”
- Incorrect: “Yes sir,” “Judge,” or the judge’s last name
It sounds like a small detail, but judges notice, and so does the jury. Get this one right every single time.
Rule #5: Never interrupt the judge, prosecutor, or witnesses
Defendants must let the judge, prosecutor, and witnesses finish speaking before saying anything, even if you disagree with what’s being said. Interrupting doesn’t make you look strong; it makes you look like you can’t control yourself under pressure.
You do have a right to remain silent under the 5th Amendment, and exercising that right, and letting your attorney do the talking, is a lot more powerful than shouting over someone in open court anyway.
If you disagree with something said in court:
- Write it down and pass a note to your attorney.
- Wait for your attorney to object or address it.
- Never argue directly with a witness or prosecutor.
The courtroom isn’t the place to defend yourself in the moment. That’s what your attorney is there for.
Rule #6: Keep emotional reactions in check
Defendants need to stay composed no matter what’s said in court, whether it’s a witness lying on the stand or a prosecutor pushing for the maximum sentence. Outbursts, eye rolls, and visible anger can influence how a judge or jury perceives you, even if your reaction is completely justified.
This matters even more in serious cases, (if, for instance, you’re facing a third degree felony, the stakes couldn’t be higher).
How to stay composed in a courtroom:
- Keep a neutral, respectful expression.
- Take slow breaths if you feel yourself getting heated.
- Lean over and whisper to your attorney instead of reacting out loud.
- Remember: the jury is watching you as much as they’re watching the evidence.
Nobody’s asking you to feel nothing. They’re asking you to not let the courtroom see it.
Rule #7: Turn off and put away phones and electronic devices
Defendants should silence and put away all phones, tablets, and smartwatches before entering the courtroom, not just during the hearing but before you even sit down. A phone going off mid-hearing is disruptive, embarrassing, and can result in the judge holding you in contempt.
It’s a rule that sounds obvious until you’re the one whose phone buzzes at the worst possible moment.
Before you walk into the courtroom:
- Silence your phone completely; don’t just put it on vibrate.
- Leave it in your bag or pocket, out of sight.
- Never text, scroll, or check notifications while court is in session.
If you’re unsure what’s allowed in your specific courtroom, ask your attorney before the hearing. It’s a quick question that could save you from an embarrassing moment later.
Rule #8: Speak only when instructed and only to your attorney
Defendants should not speak to the judge, prosecutor, opposing witnesses, or anyone else in the courtroom unless specifically instructed to do so. Every word you say in that room can be used against you, so the safest move is almost always silence, with all communication funneled through your attorney. This isn’t about hiding something; it’s about protecting yourself from saying the wrong thing at the wrong time.
Who you should talk to:
- Your attorney, quietly and only when necessary
- The judge, only when directly addressed and instructed to respond
Who you shouldn’t talk to:
- The prosecutor
- Opposing witnesses
- Jury members, ever, under any circumstance
Let your attorney do the talking. That’s exactly what you’re paying them for.
Rule #9: Follow your attorney’s lead on when to talk and when to stay silent
Defendants should trust their attorney’s judgment on courtroom timing, from when to answer a question to when to stay completely silent. Your attorney knows the judge, the prosecutor, and the unwritten rules of that specific courtroom in ways you don’t, and going off script can undo weeks of strategy in seconds. This is true whether you’re standing before a judge in Houston or fighting charges anywhere else in Texas.
Why this rule overrides your instincts:
- Your attorney has studied the case, the evidence, and the courtroom dynamics.
- A single unplanned comment can open the door to questions you’re not prepared for.
- Silence, when your attorney calls for it, is a strategic decision, not weakness.
If your attorney tells you to stay quiet, stay quiet. If they tell you to answer, answer. Second-guessing that guidance in the moment is one of the fastest ways to hurt your own case.
What happens if you break courtroom rules
Breaking courtroom rules can result in consequences ranging from a stern warning to being held in contempt of court, which can mean fines or even jail time on top of your existing charges. Judges have broad authority to control their courtroom, and they don’t hesitate to use it when a defendant steps out of line. Worse, a bad impression from breaking these rules can quietly influence how a judge or jury views the rest of your case.
Possible consequences
- Being held in contempt of court, which can carry fines or jail time
- Bond or bail revocation, especially for repeated or serious violations
- A warrant issued for failure to appear or walking out mid-hearing
- A judge or jury forming a negative impression that colors how they view your credibility
The consequences you won’t see on paper
Not every consequence comes with a formal charge attached to it. A judge who’s annoyed with your conduct has plenty of ways to make your case harder, from denying a continuance to being less lenient at sentencing. There’s no rule that says a judge has to give you the benefit of the doubt, and defendants who treat the courtroom with respect are the ones who tend to get it.
The bottom line: the rules of the courtroom exist because judges have seen every kind of bad behavior imaginable, and the legal system has ways to shut it down fast. Respect the process, and you take one more variable out of the prosecutor’s hands.
FAQs
What is the golden rule in court?
The golden rule in court is simple: respect the judge and follow instructions without question. Every rule of courtroom etiquette, from how you dress to when you speak, comes back to that one principle. Judges have enormous discretion over how your case unfolds, and respect is the fastest way to keep that discretion working in your favor.
How should a defendant behave in court?
A defendant should stay calm, dress conservatively, and speak only when instructed, ideally through their attorney. Any emotional outburst or disrespectful behavior can influence how a judge or jury views the rest of the case. Think of your behavior as evidence in itself, because a judge or jury is reading it whether you mean them to or not.
How to make the judge like you in court?
You don’t need the judge to like you, you need them to respect you, and that comes from following courtroom rules to the letter. Arrive early, dress professionally, and let your attorney do the talking whenever possible. Judges see hundreds of defendants a year, and the ones who stand out for the right reasons are the ones who took the process seriously.
How to address the judge in court?
Always address the judge as “Your Honor,” never by name or any other title. It’s one of the simplest rules to follow, and getting it wrong makes you look careless in front of the person deciding your case. This rule applies every time you speak directly to the judge, not just at the start or end of a hearing.
What to never say to a judge in court?
Never argue, make excuses, or speak out of turn to a judge, and never say anything without your attorney’s guidance. Even a single offhand comment can undo a carefully built defense strategy. If you’re unsure whether to say something, the safest answer is almost always to stay silent and let your attorney speak for you.
