Employment Tribunal Witness Statements: How to Write Yours

Written by the Aricase editorial teamHow we write our guides

This guide covers England and Wales. It is general information, not legal advice, and is not a substitute for advice about your own situation. Laws and figures change - always check the current position on GOV.UK before relying on any detail here.

  1. Collect your chronology and documents first

    Build a dated timeline and make sure the hearing bundle (or draft bundle) page numbers are stable before you draft. Your statement will refer to those pages.

  2. Write in numbered paragraphs, chronological order

    Start with who you are and your role, then set out what happened in date order. One idea per paragraph where you can.

  3. Stick to what you saw and did

    Describe events you personally experienced. Flag hearsay clearly if you must include what someone told you, and avoid speculation about motives.

  4. Cross-refer the bundle by page number

    Where a document supports a fact, give the bundle page (for example 'Bundle p.42'). That is how the tribunal follows the paper trail in your narrative.

  5. End with a statement of truth and sign

    Add the formal statement of truth, sign and date. Exchange on the tribunal's ordered date and keep an identical copy for the hearing.

For most claimants, the witness statement does more heavy lifting than anything said on the day of the hearing. Tribunals usually read statements in advance. At the hearing, your statement is often taken as read, and the live part is mainly cross-examination.

This guide explains how witness statements work in employment tribunals in England and Wales, how to structure yours, and the mistakes that undermine otherwise strong cases. It sits next to our guides on evidence, the documents map and what happens at a hearing.

What is a witness statement at an employment tribunal?

A witness statement is a written account of the facts a witness can speak to from their own knowledge. As a claimant representing yourself, you will almost always produce one for yourself. Colleagues or others who saw key events may produce their own statements if they are giving evidence.

Typical features:

  • Numbered paragraphs for easy reference in cross-examination
  • Chronological structure (with short topic headings if the claim is complex)
  • References to the hearing bundle by page number
  • A statement of truth at the end, signed and dated

The tribunal's case management orders set the exchange date. Exchange is often simultaneous - both sides serve statements on the same day.

How a statement is used at the hearing

At many hearings:

  1. The panel has already read the statements.
  2. You confirm the statement is true (with any small corrections noted).
  3. The other side cross-examines you on it.
  4. The panel may ask its own questions.

That is why a clear, careful statement is so valuable: it is your main chance to set out the story in your own words without interruption. Advocacy and legal argument still matter, but they rest on this foundation.

What to put in - and leave out

Include

  • Who you are, your role, and your employment dates
  • What happened, in order, with dates
  • Who said or did what (names and job titles)
  • Where documents support a point, the bundle page
  • The impact on you where it is relevant to remedy (for example financial loss or injury to feelings in discrimination claims) - stick to facts you can support

Leave out or minimise

  • Lengthy legal submissions (save those for the hearing or written submissions)
  • Speculation about what managers "must have known"
  • Insults and emotional rhetoric
  • New claims that are not already in your ET1 (adding late claims has its own rules)

A simple structure that works

  1. Introduction - name, address for the tribunal's records if required, role, start and end dates.
  2. Background - enough context for a stranger to understand the workplace.
  3. The events - chronological, one event or short sequence per paragraph or short group of paragraphs.
  4. After the key event - grievance, appeal, ACAS, anything that shows process.
  5. Loss / impact (if relevant) - factual, not a full schedule of loss (that is a separate document - see schedule of loss).
  6. Statement of truth - signed and dated.

Worked micro-example (style only)

12. On 5 March 2026 I attended a meeting with Sam Lee (HR) and Priya Shah (my manager). The meeting was not labelled as a disciplinary hearing in the invite (Bundle p.18).

>

13. At the meeting Priya Shah said my role was at risk of redundancy. I asked for the selection criteria in writing. Sam Lee said they would "come later". I did not receive them before my dismissal letter dated 12 March 2026 (Bundle p.24).

The point is specificity: date, people, what was said, what document proves it.

Bundle page numbers

Judges follow paper. If your statement says "see the email about the warning" without a page, the panel has to hunt. If it says "Bundle p.37", the point lands immediately.

Practical sequence many litigants in person use:

  1. Agree or prepare the bundle structure.
  2. Number the pages.
  3. Draft or finalise the statement with those numbers.
  4. If the bundle is re-paginated, update the references before exchange.

Statement of truth

Use the form of words required by the tribunal's practice or orders. In substance you are declaring that you believe the facts are true. Do not sign until you have re-read every paragraph. If something is an estimate or belief rather than direct knowledge, say so plainly.

Other witnesses

If a colleague will give evidence:

  • Their statement should be in their words, not a copy of yours.
  • They should stick to what they personally saw or heard.
  • Exchange rules still apply - late statements can be shut out.

You cannot force a reluctant colleague to give evidence, but you can ask. Tribunal witness orders exist in some situations; they are a separate procedural step and not the default first move.

Common mistakes

MistakeWhy it hurts
Narrative without datesHard to test against documents
Copy-pasting the ET1Misses hearing-focused detail and bundle refs
Legal essayReads as argument, not evidence
Ignoring awkward factsCross-examination will find them
Missing exchange deadlineRisk of exclusion or adverse case management
Unsigned / no truth statementMay not be accepted as evidence

How this fits the wider process

Witness statements usually come after the ET1 and ET3 have framed the issues, and alongside disclosure and the bundle. See the process step-by-step guide for where statements sit in the timetable, and self-representation for the wider preparation load.

Keep your deadlines calendar separate from drafting days - case management dates are as real as the original claim time limit.

Key takeaway

A good employment tribunal witness statement is chronological, specific, document-backed and honest about what you personally know. It is signed with a statement of truth and exchanged on time. Get the structure right and the hearing becomes a test of that evidence - not a scramble to tell your story for the first time under pressure.

Frequently asked questions

Do I have to write a witness statement?

If you are giving evidence - which as a claimant representing yourself you almost always are - yes. The tribunal will order a date for exchange of witness statements. Your statement is usually your evidence in chief.

How long should a witness statement be?

Long enough to cover the relevant facts clearly, short enough that a judge can follow it. Many straightforward unfair dismissal statements run to a modest number of pages; complex discrimination claims can be longer. Structure and chronology matter more than length.

Can I put legal argument in my statement?

Keep argument light. The statement is for facts you personally know. Legal labels and closing submissions belong elsewhere. Referring to the legal issue in plain language is fine; a skeleton argument is not a witness statement.

What is a statement of truth?

A signed declaration that you believe the facts in the statement are true. Knowingly making a false statement of truth is a serious matter. Read every paragraph before you sign.

When are statements exchanged?

On the date in the tribunal's case management orders - often simultaneously with the other side. Missing that date can lead to your evidence being restricted.
