You’re sitting on a wooden bench in a hallway that smells faintly of floor wax and old paper. Your palms are sweating. Maybe you’re checking your watch every thirty seconds, or maybe you’re just staring at a crack in the plaster. Being a witness to a trial is, honestly, one of the most stressful things a regular person can go through. It’s nothing like the snappy, well-lit scenes in Law & Order. It’s mostly waiting. And then, it’s a lot of pressure to be "perfect" in a system that thrives on making you look like you’re lying.
The American legal system relies almost entirely on the idea that humans can remember things accurately. But here’s the kicker: we’re actually kind of terrible at it.
Why Your Memory is the Enemy
Most people think their brain works like a GoPro. You hit record, and later, you just play back the footage. Science says otherwise. Dr. Elizabeth Loftus, a cognitive psychologist who has spent decades studying human memory, has proven over and over that our memories are incredibly malleable. If a lawyer asks you, "How fast was the car going when it smashed into the pole?" you are likely to remember a higher speed than if they used the word "hit."
When you’re a witness to a trial, your brain is trying to fill in the gaps. You want to be helpful. You want to tell a coherent story. But "coherent" isn't always "accurate." In a courtroom, those tiny gaps are where the defense or prosecution will dig their heels in. They aren't just testing your integrity; they’re testing the biology of your brain.
The Reality of the Subpoena
If you’ve received a subpoena, you aren't there as a volunteer. It’s a court order. Ignore it, and you’re looking at a contempt of court charge, which can mean fines or even jail time. You’ve basically been drafted into the legal war.

Sometimes, people think they can just "explain things" to the judge before the trial starts. It doesn't work that way. Once you’re on that witness list, you’re a piece of evidence. You belong to the record.
Cross-Examination Isn't About the Truth
This is the part everyone fears. And rightfully so. Cross-examination is a tool designed to discredit you. It’s not a conversation. It’s an interrogation. A common tactic is the "yes or no" trap. The lawyer will ask a complex question—something like, "Isn't it true you were angry when you left the bar?"—and demand a one-word answer.
They want to strip away the context. They want to make you look biased, confused, or just plain dishonest. Honestly, the best defense is to stay boring. The more emotional you get, the more the jury starts to doubt your objectivity. If a lawyer is being a jerk, let them. If you stay calm while they’re shouting, they’re the one who looks bad to the jury.
The Different Flavors of Witnesses
Not every witness to a trial is there to say what they saw. You’ve got your "lay witnesses"—people who saw the crash or heard the gunshot. Then you’ve got "expert witnesses." These are the folks getting paid $500 an hour to explain DNA sequencing or tire tread patterns.

There's a huge difference in how the jury treats these two groups. Lay witnesses get empathy. Expert witnesses get scrutiny. If you're a lay witness, the jury wants to believe you because you're "one of them." Don't lose that by trying to sound like a legal expert. Just be a person.
What Happens Behind the Scenes
Before you ever step into the courtroom, there’s a process called "sequestering." Basically, the judge might order all witnesses to stay out of the courtroom until it’s their turn to testify. This is so you don't hear what other people are saying and subconsciously change your story to match theirs. You might spend six hours in a small room with nothing but a 2014 issue of National Geographic and a lukewarm coffee. It’s grueling.
The "Overt" Mistakes People Make
- Speculating. If you don't know, say "I don't know." People hate saying that. We feel stupid. But in court, "I don't know" is the safest sentence in the English language.
- Looking at your lawyer for help. When you’re stuck, don't glance at your lawyer. The jury sees that. They think you’re looking for a signal.
- Answering too fast. Take a breath. It gives your lawyer a chance to object if the question is out of bounds.
- Getting chatty. Once you answer the question, stop talking. Silence is uncomfortable, and lawyers use that silence to bait you into saying something extra that you’ll regret later.
A Word on Ethics and Perjury
Lying under oath—perjury—is a felony. But here’s the nuance: being wrong is not the same as lying. If you honestly believe the light was green, but the traffic camera shows it was red, you haven't committed perjury. You've just made a mistake. Perjury requires "intent." You have to know you’re lying and do it anyway to influence the case.
The Psychological Toll
Nobody talks about the "witness hangover." After you testify, you might feel a weird mix of adrenaline and total exhaustion. You’ve been the center of attention in a high-stakes environment where people were literally paid to doubt your every word. It’s okay to feel rattled.

Many jurisdictions now offer "victim-witness advocates." These are professionals whose whole job is to help you navigate the system. If you’re a witness to a trial involving a violent crime, use these people. They can help you find a safe place to wait and explain the jargon that the lawyers are throwing around.
How to Prepare (The Actionable Part)
If you've been called to testify, don't just wing it.
- Review your original statement. If you gave a police report two years ago, read it. Your memory will have faded, but the prosecution will use that old document to "refresh" your memory on the stand. You don't want to be surprised by your own words.
- Visit the courtroom ahead of time. Most courtrooms are open to the public. Go sit in the back for an hour a few days before you testify. Get used to the acoustics, the height of the witness stand, and where everyone sits. It takes the "spookiness" out of the room.
- Dress for a job interview. You don't need a tuxedo, but you need to show the court respect. It’s a performance, whether we like it or not.
- Listen to the whole question. Don't start forming your answer halfway through. Wait for the lawyer to finish. If they use a double-negative or a confusing phrase, ask them to rephrase it.
- Speak to the jury. When you're answering, look at the jurors. They are the ones making the decision. The lawyer is just the messenger.
- Keep your "I think" and "I believe" separate from "I saw." Be precise. "I saw the blue car" is very different from "I think the car was blue."
The legal system is a machine. As a witness to a trial, you are a vital part of that machine, but you are also vulnerable to it. Stay calm, stay honest, and remember that you aren't the one on trial—even if it feels like it.
