Witness statement collection is the practical process of identifying the people who can prove relevant facts, preserving their own recollection, gathering the documents they genuinely need, and turning that evidence into clear witness statements that comply with the court's directions. This guide is for civil proceedings in England and Wales. Scotland and Northern Ireland use different procedural rules.
What “witness statement collection” should mean in practice
A witness statement is not simply a narrative produced from the case file. It is written evidence from a particular person. The collection stage therefore begins before drafting: decide which disputed facts need witness evidence, who actually has first-hand knowledge of those facts, and what each witness can add without duplicating another witness.
For civil proceedings in England and Wales, CPR Part 32 and Practice Direction 32 are the starting points. Practice Direction 32 requires the statement, so far as practicable, to be in the witness's own words and in their own language. It must distinguish matters within the witness's own knowledge from information or belief and identify the source of matters that are not first-hand. Those requirements should shape the collection process from the first interview, not be added at the end.
The first control document should be a witness evidence matrix. List each issue that genuinely requires factual evidence, the proposed witness, the event or fact they can address, the documents they may need to see, and the deadline in the court order. This prevents a common failure: collecting long statements that are detailed but do not prove any issue the court must decide.
1. Start with the court order, issues and deadline
Before contacting witnesses, read the latest order and any applicable court guide. Record the date for exchange or service of witness statements, whether statements are simultaneous or sequential, whether there is a page or word limit, whether evidence is restricted to particular issues, and whether the court has made directions about exhibits, translations or electronic bundles.
Do not assume that a generic timetable applies. A direction in the case takes priority over a workflow copied from another matter. If the deadline is approaching, build backwards from the service date: witness interview, first draft, factual verification, exhibit checking, final review, signature and service each need time. The collection plan should identify who is responsible for every step.
At this stage separate evidence from submissions. A witness normally proves facts. Legal argument belongs in statements of case, skeleton arguments or submissions unless a particular factual explanation is genuinely within the witness's knowledge. Keeping that distinction clear makes the statement easier to read and reduces the risk that the witness appears to be arguing the case rather than giving evidence.
2. Build a witness list by issue, not by job title
Identify witnesses because of what they personally saw, heard, did, received or decided. A senior manager is not automatically the best witness if the relevant events were handled by somebody else. Conversely, one witness may be able to cover several connected events if they were directly involved throughout.
For each candidate witness, record: full name; role at the relevant time; relationship to the parties; the events they can address; whether their knowledge is first-hand; any important gaps in recollection; key documents they created or received; availability; language needs; and any reason why obtaining a signed statement may be difficult.
Then compare the witness list with the pleaded issues and the documents already available. Look for gaps. If an important fact currently depends only on a document whose meaning is disputed, ask who created, received or acted on that document. If two witnesses cover exactly the same point, decide whether both are necessary or whether their evidence is genuinely different.
3. Preserve the witness’s own recollection before showing too much material
The quality of witness evidence depends on preserving the difference between memory and reconstruction. Start an interview by asking the witness to describe the events in their own sequence and language. Use open questions first: what happened, who was present, what was said, what did the witness do next, and what do they actually remember now?
Only after capturing the witness's unaided recollection should you use documents to test dates, identify missing events or refresh memory where appropriate. Keep a record of documents shown to the witness. If a document changes or refreshes the witness's recollection, record that fact rather than silently rewriting the account as if the witness had always remembered it.
This distinction is particularly important for trial witness statements in the Business and Property Courts, where Practice Direction 57AC imposes additional requirements about personal knowledge, recollection and documents used to refresh memory. PD57AC is not a universal rule for every civil witness statement, so first determine whether it applies to the proceeding.
4. Conduct a structured witness interview
A useful interview follows the chronology but is organised around the issues. Begin with identity and role, then move through the relevant events. For each material fact ask how the witness knows it. If the answer is “someone told me”, identify that person and the circumstances. If the answer comes from a document, identify the document and distinguish what the witness remembers independently from what the document shows.
Do not fill gaps by suggestion. Where the witness cannot remember, record the uncertainty. A careful statement that says a date is not independently remembered but is confirmed by a contemporaneous email is generally more reliable than a confident date inserted by the drafter. Likewise, do not convert an inference into an observed fact. “I understood X because…” is different from “I saw X”.
At the end of each topic, summarise the account back to the witness and ask whether anything is wrong, missing or overstated. Note contradictions with contemporaneous documents for follow-up. A contradiction is not automatically a reason to discard the witness; it is a reason to establish what the witness can honestly say and whether the discrepancy needs explanation.
5. Record how the statement was prepared
Practice Direction 32 requires the statement to identify the process by which it was prepared, for example face-to-face, by telephone and/or through an interpreter. Keep that information during collection so it is not reconstructed later.
If an interpreter is used, record the language, the interpreter's details and the stages at which interpretation was provided. The statement should be in the witness's own language. Translation requirements should be checked against the current procedural rules and any case-specific direction before service.
For remote interviews, keep a clear attendance record: date, participants, method, start and finish time, documents shared, and any later corrections requested by the witness. This is useful version-control evidence and helps resolve disputes about whether wording came from the witness or the drafter.
6. Separate personal knowledge from information and belief
PD32 requires a witness statement to indicate which statements are made from the witness's own knowledge and which are matters of information or belief, and to state the source of the latter. This is a collection problem as much as a drafting problem.
For every significant proposition, ask: did the witness personally perceive this, learn it from another person, infer it from records, or understand it from their professional role? The answer determines how the point should be expressed. If the source is another person, identify the source where appropriate. If the source is a record, identify the record accurately.
A source-control table can be simple: proposition, source type, witness recollection, supporting document, exhibit reference and any conflict. The table need not be filed; it is a quality-control tool. It prevents unsupported assertions from entering the final statement merely because they appear elsewhere in the case file.
7. Draft in chronological, numbered paragraphs
PD32 states that witness statements should be divided into numbered paragraphs and that it is usually convenient to follow the chronological sequence of events, with each paragraph dealing as far as possible with a distinct part of the subject. Use that structure unless the nature of the evidence makes another structure clearer.
The opening should identify the witness, their relevant role or occupation, relationship to the case and the basis of their knowledge. The body should then move through the facts in a logical order. Use dates and document references precisely. Avoid argumentative headings, rhetorical questions and adjectives that add heat rather than evidence.
Where the witness is unsure, preserve the qualification. Where an event is remembered approximately, say so. Where the witness relies on a record to identify a date, make that clear. A statement does not become stronger by disguising uncertainty.
8. Collect and control exhibits separately
An exhibit is not part of the witness statement merely because the statement refers to it. PD32 provides that an exhibit used with a witness statement should be verified and identified by the witness and remain separate from the statement. The rules also address exhibit numbering, legibility and bundles.
Collect only documents that genuinely support or explain the evidence. Give each exhibit a stable reference. If there are multiple documents in an exhibit, prepare a list and keep the documents in a logical order. Correspondence is normally easier to use when chronological. Check that every referenced exhibit exists, that the exhibit mark in the statement matches the bundle, and that pagination will not change after signature without controlled correction.
Do not exhibit court documents merely to make the bundle look complete. PD32 specifically addresses the treatment of court documents and exhibits. The objective is usable evidence, not volume.
9. Check the statement of truth and signature stage carefully
A civil witness statement must be verified by the appropriate statement of truth. CPR Part 22 and PD32 govern verification. Use the current prescribed wording from the Civil Procedure Rules rather than an old precedent. The witness must understand that the statement confirms their belief in the truth of the facts stated and that false verification without an honest belief can have serious consequences.
Before signature, send or read the entire final statement to the witness together with the exhibits they are asked to verify. Ask the witness to check names, dates, quotations, sequence, document references and any expression of uncertainty. Corrections should be made before signature where possible, with versions clearly controlled.
Do not treat signature as an administrative formality. The final text should be the evidence the witness adopts. Keep a copy of the signed version and a record of how and when it was signed and returned.
10. Serve the correct version and preserve proof of service
After signature, compare the statement against the court order one final time. Confirm the witness name, statement number, date, case number, exhibits, statement of truth, signature and any required translation. Check the permitted method of service and the deadline.
Use a version name that cannot be confused with a draft. Record the exact file served, recipient, method, date and time, and retain delivery evidence. If a bundle platform is used, preserve the upload confirmation. If email service is permitted, retain the sent message and attachments rather than relying only on an inbox copy.
If an error is discovered after service, do not silently replace the document. Assess whether a corrected or supplemental statement is required and whether permission or agreement is needed under the applicable directions.
What if you cannot obtain a witness statement?
CPR 32.9 provides a mechanism for a party who is required to serve a trial witness statement but is unable to obtain one: the party may apply for permission to serve a witness summary. A witness summary is not simply a substitute chosen for convenience. The rule requires the appropriate application and the court controls whether it may be used.
If a witness is reluctant, unavailable or cannot sign by the deadline, record the attempts made and identify the issue early. The correct response may be an application, a request for directions, or a change in the evidence plan. Waiting until the service deadline has passed usually reduces the available options.
Additional rules for Business and Property Courts trial statements
Practice Direction 57AC applies to trial witness statements in specified Business and Property Courts proceedings. It is stricter than the general PD32 framework in several respects. It emphasises that the purpose of a trial witness statement is to set out matters of fact within the witness's personal knowledge, not to argue the case or take the court through documents.
The collection process should therefore identify what the witness actually remembers, how well they remember it, and which documents were used to refresh that memory. The statement also requires the additional confirmations and certificate of compliance prescribed by PD57AC unless the court orders otherwise. If PD57AC applies, build those requirements into the first interview rather than attempting to repair the statement immediately before exchange.
Common witness statement collection failures
- Starting with a precedent instead of the issues: the resulting statement is long but does not prove the disputed facts.
- Showing the whole disclosure set before recording memory: the witness's own recollection becomes difficult to distinguish from reconstruction based on documents.
- Using identical wording for several witnesses: this can obscure whose evidence it really is and create avoidable credibility questions.
- Failing to distinguish knowledge from information or belief: the source of an important assertion becomes unclear.
- Exhibiting everything: oversized exhibits make the evidence harder to navigate and increase the chance of inconsistent references.
- Changing pagination or exhibit numbers after signature: the signed statement no longer matches the served material.
- Using an outdated statement of truth: verification should be checked against the current CPR wording.
- Ignoring case-specific directions: even a technically well-drafted statement can be late, over-length or outside the permitted scope.
A practical collection checklist
- Read the latest order, CPR Part 32, PD32 and any applicable specialist practice direction.
- List the factual issues that genuinely require witness evidence.
- Map each issue to the person with first-hand knowledge.
- Record witness availability, language requirements and service deadline.
- Interview using open questions before using documents to refresh memory.
- Record how the statement was prepared and which documents were shown.
- Separate personal knowledge from information, belief and inference.
- Draft in the witness's own words and language, using numbered paragraphs.
- Build a controlled exhibit list and verify every cross-reference.
- Use the current statement of truth and obtain the witness's informed approval.
- Serve the signed final version by the permitted method and preserve proof.
- Keep a version log so a later correction can be traced.
