Drafting an effective witness statement

Telling the court what you saw — and keeping out what you merely think

A witness statement is your evidence in writing. It is one of the most important documents in a case, and one of the easiest to get wrong. This guide explains what a good statement does, the crucial difference between fact and opinion, and shows — with worked examples — how to turn weak drafting into strong. It is general guidance; I can draft or settle your statement for you if you instruct me.

What a witness statement is for

A witness statement sets out, in your own words, the facts you can prove from your own knowledge. It stands as your evidence-in-chief — what you would have said out loud — and you may be cross-examined on it. So every sentence must be something you genuinely know and would be willing to stand behind in the witness box. It must be in your own words, in the first person, and end with a signed statement of truth confirming you believe its contents are true. Knowingly putting forward a false statement is contempt of court.

Fact versus opinion — the distinction that matters most

As an ordinary (lay) witness, you give evidence of fact: what you saw, heard, did, and said. You are generally not allowed to give opinion — your interpretation, conclusion, or what you think it all means. Opinion evidence is reserved for properly-instructed expert witnesses. The judge draws the conclusions; your job is to give them the raw material.

Fact — include this

“On 3 March the delivery arrived at 9.15am. Eleven of the forty boxes were crushed on one side.”

“He raised his voice and said, ‘You will never see that money.’”

“I emailed him twice, on 4 and 11 March. He did not reply to either.”

Opinion — leave this out

“The goods were obviously defective and unfit for sale.”

“He was clearly trying to threaten and intimidate me.”

“It was plain he never intended to pay — he is a dishonest man.”

The facts on the left let the judge reach the conclusions on the right — far more powerfully than if you assert them yourself. Show, don’t tell.

Worked examples — weak into strong

Example 1 — a disputed conversation

Weak

“The builder was completely unreasonable and aggressive about the money and basically refused to fix any of the obvious problems with the work.”

Strong

“On 12 April I asked Mr Hughes to return and re-lay the patio, which had sunk by about 4cm at the south end. He said, ‘I’ve been paid, I’m not coming back.’ He did not return. The photographs at pages 14–16 show the patio as it was that day.”

The strong version gives a date, the exact words, a measurement and a document reference — and lets the judge decide who was unreasonable.

Example 2 — what someone else told you

Weak

“Everyone knew the company was about to go under and that he was moving money out before it did.”

Strong

“On 2 June the finance manager, Sarah Patel, told me the company could not meet July’s payroll. I have no direct knowledge of the company’s accounts. I saw three transfers of £5,000 leave the account on 5, 6 and 7 June, shown at page 22.”

If you must include something you were told (hearsay), say who told you and when, and be clear about the limits of your own knowledge. Never dress up rumour as fact.

How to structure it

—Head it with the case details, your full name, address and occupation, and number it as your statement.
—Use short, numbered paragraphs, and tell the story in date order.
—When you refer to a document, say where it is (“page 14 of the bundle”); do not paste documents into the text.
—Stick to what is relevant to the issues. Length is not strength; a focused statement reads as more credible.
—End with: “I believe that the facts stated in this witness statement are true,” then sign and date it.

The cross-examination test. Before you finalise it, read each sentence and ask: “Could I be challenged on this, and would it hold?” Anything you cannot stand behind — a guess, an exaggeration, an opinion dressed as fact — is a weakness the other side will find. Take it out.

Before you sign — a final check

Every paragraph is fact you know first-hand — opinion and argument removed.
Dates, names, figures and exact words are accurate and checked against the documents.
Anything heard from someone else is identified as such, with who and when.
It is in your own words, in date order, and ends with a signed statement of truth.
