Preparing to Give Evidence
Why Preparation Matters
Preparation for giving evidence is not optional. A witness who arrives at a hearing unfamiliar with the documents, unsure what to expect, and unprepared for the structure of questioning is far more likely to become confused, anxious, or inaccurate under pressure. They are also more likely to make avoidable mistakes that damage their credibility: misremembering dates, contradicting their own witness statement, or being surprised by a document they should have reviewed.
At the same time, preparation has clear limits. The court expects witnesses to give evidence based on genuine independent recollection. Preparation that crosses the line from refreshing memory and understanding process into rehearsing answers or aligning evidence with a case strategy is improper and potentially unlawful. The challenge for every witness and the professionals supporting them is to prepare thoroughly and appropriately within those boundaries.

Reviewing the Documents
Reviewing the key documents in the trial bundle before giving evidence is an important and entirely appropriate part of preparation. Judges place significant weight on contemporaneous documents such as emails, meeting notes, contracts, letters, and diary entries. These documents provide the timeline and wording against which oral evidence is tested. A witness who has not looked at them for months is likely to feel wrong-footed in the witness box, even if their underlying account is honest.
The purpose of reviewing the bundle is to refresh familiarity with the material so questions can be answered accurately and confidently. Re-reading documents can jog memory, help locate events in time, and remind the witness of the exact language used at the time. When reviewing, pay attention to the sequence of events, key communications, and any documents you authored or received. If a document surprises you, note it and discuss it with your legal team before the hearing. A witness who has engaged with the bundle carefully is usually calmer, more accurate, and better able to assist the court.
It is also important to understand what documents reliably show and what they do not automatically prove. A document records what was written or sent at a particular time. It does not automatically prove that it was read, understood, agreed, or acted upon. Witnesses who over-interpret documents, or who attribute meaning not evident on the face of a document, often come unstuck under cross-examination.
Reviewing Your Witness Statement
In most civil cases, your witness statement stands as your evidence in chief. Cross-examination will frequently take you directly to specific paragraphs, phrases, or assertions you have signed. Re-reading your statement before giving evidence is essential. It refreshes your recollection of what you said, the language you used, and the structure of your account. It also helps you avoid being unsettled when an advocate puts your own wording to you during questioning.
The purpose is not to memorise a script. It is to make sure you are familiar with your own evidence so you can answer questions confidently and accurately. If you notice anything in your statement that you now wish to correct or clarify, discuss this with your legal team before the hearing rather than trying to introduce corrections from the witness box unannounced.
Where you have access to other witnesses’ statements, approach them with caution. Reading them can help you understand the broader factual picture, but you must not allow them to overwrite your own independent memory. Your duty is to give your own truthful evidence. If there are differences between your statement and another witness’s account, raise this with your legal team.
Mental Preparation
The mental and emotional demands of giving evidence are real and should not be underestimated. Being questioned in a formal setting, under oath, by an advocate who may challenge your recollection and your credibility, is a stressful experience for almost everyone. Mental preparation is not about convincing yourself that it will be easy. It is about understanding what to expect so that the experience is less shocking and disorienting when it arrives.
Understanding the structure of questioning, the nature of cross-examination, and what judges are looking for significantly reduces the anxiety of the unknown. Witnesses who have been through witness familiarisation training consistently report that the experience, though still stressful, is far less overwhelming than they anticipated because they understood what was happening and why.
Sleep, rest, and basic physical wellbeing matter on the day. Giving evidence requires sustained concentration. Fatigue and stress both impair the quality of evidence. If you have the opportunity to rest before giving evidence, take it seriously.
Practical Preparation for the Day
Plan your travel carefully and build in significant extra time. Arriving late to a hearing where you are required to give evidence is an extremely poor start and increases anxiety dramatically. Check the route, the parking, and the entrance to the court or tribunal building in advance if you can. Know who to contact if something goes wrong on the day.
Dress professionally and appropriately for the proceedings. Your appearance is the first impression the judge forms before you say a word. Courts and tribunals do not expect witnesses to wear formal legal attire, but they do expect a respectful standard of dress. Smart, professional clothing that would be appropriate for an important business meeting is generally the right level.
Be thoughtful about your recent social media activity. Contemporaneous posts about the dispute, the other party, or your own situation can be found and used. They can also create inconsistencies with evidence you give in the witness box. If you have concerns about anything you have posted, discuss it with your legal team before the hearing.
What Appropriate Preparation Looks Like
Appropriate preparation includes reading the trial bundle to refresh familiarity with key documents, dates, and communications; reviewing your own witness statement; understanding what cross-examination involves and why questions are often closed, leading, and repetitive; identifying areas where your memory is strong and where it is uncertain; and understanding the practical arrangements for the hearing. It does not include rehearsing answers to anticipated questions, refining wording to sound more persuasive, memorising timelines or phrases, or aligning your evidence with the legal case strategy. The line between the two is ethical as well as practical, and it must not be crossed.

Frequently Asked Questions
Can I review my witness statement before giving evidence?
Yes. Reviewing your own witness statement before giving evidence is an entirely appropriate and important part of preparation. Its purpose is to refresh your recollection of what you said, not to memorise or modify it.
What should I do if I realise something in my witness statement is incorrect?
Tell your legal team as soon as possible. Do not try to correct or change your statement from the witness box without having raised it with your lawyers first. There are proper procedural routes for correcting a statement before the hearing.
Is it helpful to visit the court before the hearing?
Yes, where possible. Understanding the physical environment of the court or tribunal in advance reduces one source of anxiety. Most courts are open to the public for hearings. Attending as a public observer beforehand can be a useful way to become familiar with the environment.
