Whether you’re stepping into the witness box for the first time as an aspiring expert or you’re a seasoned pro with years of experience behind you, cross-examination is rarely comfortable.
You may be a leader in your field, used to boardrooms, conference stages, or operating theatres – but the courtroom is different. The stakes are high, the rules are formal, and the advocate’s job is to test your evidence, not to make you look good.
The good news? With the right preparation, you can handle cross-examination with composure, clarity, and credibility.
In this guide, we’ll walk through five practical cross examination tips for witnesses that apply to both aspiring and experienced experts, with a focus on:

In everyday professional life, you’re used to being treated as the authority. People come to you for answers. In cross-examination, the dynamic flips:
For an aspiring expert, this can feel intimidating. For a seasoned pro, it can be frustrating – especially if you feel your expertise is being misunderstood or misrepresented.
That’s exactly why structured preparation matters. Let’s get into the five key cross examination tips for witnesses that will help you before you ever step into the box.
One of the most important cross examination tips for witnesses – especially expert witnesses – is to remember who you serve.
You are not there to “win” for the party who has engaged you. Your primary duty is to the court. That means you are there to provide independent, impartial evidence – not to promote a particular outcome. The more clearly you hold this in mind, the easier it becomes to stay calm under cross-examination, even when questions feel loaded or confrontational.
Independence starts with how you answer. You give your evidence as you genuinely see it, based on your expertise and the material you have reviewed. If a fair and honest answer happens not to assist the side that instructed you, you still give that answer without hesitation. Courts and tribunals place the greatest weight on experts who are visibly prepared to make concessions where appropriate.
A crucial part of this role is resisting the temptation to argue, advocate, or “spin” your evidence. Advocacy belongs to the barristers. The moment you slip into trying to “help your side” by debating, defending every point, or stretching your conclusions, you risk looking partisan rather than professional. In practice, your credibility – and the value of your evidence – is highest when you remain measured, neutral, and focused on assisting the court.
If you’re new to the witness box, it’s easy to feel you must “defend” the side that hired you. But advocacy is the barrister’s job, not yours. When you try to argue the case, you risk:
If you’ve been instructed in multiple matters, you may feel a sense of loyalty to your instructing solicitors. That’s natural – but in court, your professional reputation depends on your perceived independence.
Judges and tribunals are experienced in assessing whether an expert is genuinely neutral or subtly partisan. Staying firmly in the role of independent adviser to the court is the best long-term strategy for your credibility.
Practical takeaway:
Before you step into the witness box, remind yourself:
“My role is to assist the court. I am here to give clear, honest, impartial evidence – nothing more, nothing less.”
When people talk about how to handle cross-examination, the focus is often on how to give the “right” answer. In reality, the quality of your answers depends first on the quality of your listening. If you do not fully understand the question, even the most carefully prepared evidence can appear inconsistent.
In cross-examination, questions may be long, technical, or deliberately tightly framed. They may repeat earlier questions with a slight change of wording, or invite you to agree with a proposition that does not accurately reflect your report. If you respond too quickly or only partially listen, you risk agreeing to something you do not in fact accept.
Witness box tips for better listening
Pause before answering.
A brief pause to ensure you have understood the question is entirely appropriate. It allows you to consider both the words used and what you are actually being asked to agree with or comment on.
Break down complex questions.
If a question is long, multi-part, or potentially ambiguous, you are entitled to ask for clarification. For example, you might say:
Ask for repetition if needed.
If you did not hear or follow the question in full, you can simply say:
Correct misstatements calmly.
If counsel puts a proposition to you that does not reflect your evidence, address it in a measured way. For instance:
By listening carefully, taking a moment before you respond, and using respectful, precise language, you protect both the integrity of your evidence and your credibility with the court.
You might feel pressure to answer quickly to show confidence. Resist that urge. A measured, thoughtful response demonstrates professionalism, not uncertainty.
If you’ve given evidence many times, complacency can creep in. You may assume you know where a question is going. That’s when subtle traps are most effective. Treat every question as if it’s the first time you’ve heard it.
Practical takeaway:
Slow down. Listen fully. Only answer the question actually asked – nothing more.
When it comes to answering questions in court, three principles will serve you well every time:
Judges and juries may not share your technical background. Avoid jargon where possible, and if you must use it, explain it briefly.
Short, direct answers are usually best:
Then, if necessary and allowed, you can briefly explain.
If you don’t know, say so. If you need to check a document, say so. If you’ve made a mistake, correct it as soon as possible.
For both aspiring and seasoned experts, honesty under pressure is one of the most powerful ways to build trust with the court.
One of the most important cross examination tips for witnesses is knowing where your expertise ends. Trying to “have a go” at a question you’re not qualified to answer can seriously undermine your overall evidence. Your credibility is more important than any single answer. Clear, honest, and bounded responses are your best protection.
Even for experienced professionals, the witness box can trigger nerves. You’re under oath, the room is formal, and your evidence is being scrutinised.
How you manage your body language, tone, and pace can make a real difference to how your evidence is received.
Breathe and ground yourself
Before you enter the courtroom, take 5-10 minutes for a simple breathing practice. This helps settle your nervous system, reduce physical signs of stress and support clearer thinking under pressure. Research shows that slow, controlled breathing can lower stress and improve emotional regulation.
Here are a few practical options you can use before giving evidence:
Diaphragmatic breathing (about 5 minutes)
Sit or stand comfortably and place one hand on your abdomen. Breathe in through your nose for a count of four, allowing your abdomen to expand. Then exhale gently through your mouth for a count of six, letting the abdomen fall. Continue for 4-6 minutes. This type of breathing is linked with reduced stress and better emotional control.
Slow-paced breathing at around six breaths per minute (5-10 minutes)
Inhale through your nose for about five seconds and exhale for about five seconds. Aim for roughly six breaths per minute. Practise this for 5-10 minutes. Slow-paced breathing of this kind is associated with a calmer physiological state and lower anxiety.
Box breathing (3-5 minutes)
Breathe in through your nose for a count of four, hold for four, exhale through your mouth for four and hold again for four. Repeat this “box” pattern for 3-5 minutes. Box breathing is widely used in high-pressure environments to support focus and steady attention.
If you prefer guidance, you can use a short 5-minute guided breathing practice from a reputable medical or mindfulness centre.
Once you are in the witness box, place your feet flat on the floor and sit upright but not rigid. Take a couple of slower breaths before you start answering questions. This simple routine can help steady your voice, reduce visible nerves and support a calm, professional manner.
Maintain a steady pace.
Look at the questioner, then the judge.
Keep your tone neutral.
Use documents confidently.
You might worry that visible nerves will undermine your evidence. In reality, judges understand that giving evidence is stressful. What matters is that you remain honest, consistent, and composed enough to communicate clearly.
Your challenge may be the opposite: avoiding over-confidence or irritation. If you appear dismissive or combative, it can harm your perceived impartiality. Aim for steady professionalism, not dominance.
Practical takeaway:
Your demeanour is part of your evidence. Calm, measured behaviour supports the substance of what you say.
The final – and arguably most important – of our cross examination tips for witnesses is simple:
Do not treat cross-examination as something you can “wing”.
Whether you are new to the witness box or have been there many times, structured preparation is essential.
Effective preparation is more than re-reading your report on the way to court. It’s a deliberate process that helps you understand your own evidence, anticipate challenge, and feel at ease with the procedure.
Set aside some uninterrupted time to go back through your material – not just a quick skim the night before. Re-read your main report, any appendices, calculations, and joint expert statements. As you go, check that you still stand by each conclusion and that you could explain, in plain language, how you reached it.
Pay particular attention to sections that rest on important assumptions, rely heavily on another expert’s work, or are likely to be controversial. For each of these points, remind yourself what you relied on (documents, data, examinations), why you chose that approach over other options, and what reasonable limitations or uncertainties you recognised at the time.
If anything has changed – for example new information, updated guidance, or an error you have noticed – make a simple note of what has changed, why, and how it affects your opinion. Being clear about this in advance will make it much easier to deal with questions calmly in cross-examination.
Cross-examination will usually focus on the real points of disagreement, not every line of your report. Where possible, speak with the instructing solicitor beforehand and clarify which parts of your evidence are agreed and which are challenged, and how those points fit into the overall issues the court has to decide.
Many experts find it helpful to create a one-page summary of the key issues. For each issue, write down your opinion in one or two sentences and note the main criticism you expect from the opposing side. This simple exercise gives you a clear mental map of where the pressure is likely to come from and reduces the risk of being taken by surprise on an obvious point.
Knowing the material is one thing; expressing it clearly under pressure is another. For that, practice makes a real difference.
Try arranging a short, informal session with a colleague, coach, or legally trained friend who can play the role of opposing counsel. Ask them to put to you the kinds of challenges you are likely to face, such as:
Answer as you would in court, in full sentences and without rushing. If that is not possible, record yourself on your phone while you work through likely questions. When you watch or listen back, look for habits that might undermine your evidence – talking too fast, volunteering unnecessary information, becoming defensive, or drifting outside your expertise. Aim for short, clear answers that deal with the question and then stop.
Even experienced professionals can feel unsettled simply because the environment is unfamiliar. A little procedural knowledge goes a long way.
Before the hearing, make sure you know where you will sit, who will ask you questions, and in what order (for example, examination-in-chief, cross-examination, re-examination). Find out how documents will be shown to you – whether you will have a hard-copy bundle, an electronic bundle on a screen, or both. It can also help to check how the judge should be addressed in that particular court and to remind yourself of basic etiquette, such as waiting for the full question before answering and speaking slowly enough for the judge and the transcript writer.
You might even rehearse a few neutral phrases you are likely to need, such as “Could I have a moment to find that page?” or “For accuracy, may I refer to my report?”. When these phrases are familiar, it is easier to stay calm and focused.
Finally, think about whether a formal witness familiarisation session would be helpful. This can be useful both for an aspiring expert and for a seasoned professional who has not been in court for some time or is appearing in a new jurisdiction.
These programmes do not tell you what to say or shape the substance of your evidence. Instead, they walk you through the process, give you realistic practice in being questioned, and help you develop habits of listening carefully, pausing, and giving clear, bounded answers. For many experts, that structured rehearsal is the difference between feeling on edge and feeling prepared when they step into the witness box.
Practical takeaway:
Treat cross-examination as a professional skill that can be learned, practised, and refined – not as a test of raw nerve.
