Witness Statements in Commercial Litigation

Harper James advises ambitious businesses on witness statements and commercial disputes under the laws of England and Wales. A well-prepared statement sets out what a witness personally knows, links that evidence to the issues in dispute, and supports the business’s case without becoming argument dressed as fact.

What a witness statement must achieve

A witness statement is usually served as the witness’s evidence in chief at trial. It should use the witness’s own words, follow a clear chronology, identify the source of important facts, and refer to relevant contemporaneous documents. The witness signs a statement of truth, so accuracy matters. A statement that contains speculation, reconstructed conversations or unsupported opinion weakens credibility and creates cross-examination risks. Current judicial practice places close attention on the difference between genuine recollection and matters adopted from documents or discussions during preparation. The latest practical guidance on witness evidence provides useful further reading for businesses and legal teams.

The preparation process

Preparation starts with the pleaded issues and the documents, not with asking a witness to produce a broad narrative. The legal team should identify each fact that requires evidence, interview the witness carefully, test their recollection against emails, contracts, meeting notes and financial records, and record where memory is uncertain. Witness familiarisation is appropriate, including explaining the trial process and reviewing the statement. Coaching a witness to change evidence or give a preferred answer is not. The final document should contain only evidence that the witness can honestly adopt and explain.

Common commercial risks

Problems arise when a statement becomes too long, repeats the company’s legal submissions, introduces facts not pleaded, or relies on documents the witness cannot explain. Businesses should preserve original records, avoid informal discussions about what a witness should say, and identify former employees or overseas witnesses early. Where a witness is unavailable, the litigation team should address the procedural requirements for a witness summary or other evidence well before trial. Harper James can help directors, in-house teams and external witnesses organise the factual record, assess evidential gaps and prepare statements that are accurate, focused and commercially relevant.
