Preparing a clear evidence file can make a UK small claim easier to understand and manage. This checklist explains what to collect, how to organise it, what to leave out, and when to review your evidence before filing or attending a hearing.
Overview
Evidence is the material that supports the facts you rely on in your claim or defence. It should help answer four practical questions: what was agreed, what happened, what loss resulted, and what remedy is being requested.
For many claims, useful evidence includes the contract or order, invoices, payment records, photographs, relevant messages, complaint correspondence, and a calculation of the money sought. A witness statement may explain the events in your own words, while an expert report may be needed where the issue cannot be assessed fairly without specialist knowledge.
A “bundle” is often used to describe an organised collection of documents. However, do not assume that every small claim requires a large formal court bundle in the same format as a more complex civil case. The court will usually give directions explaining what documents, statements or evidence must be filed and when. Read those directions carefully and follow the applicable court process.
This article is general guidance for civil claims in England and Wales. Procedures can differ in Scotland and Northern Ireland, so check the relevant court service and forms for the jurisdiction in which the claim is being made. You can also review the Letter Before Action UK guide before issuing a claim.
What to track
1. The agreement and disputed terms
Start with the documents that show the legal relationship between the parties. Depending on the dispute, this may include:
- a signed contract or terms and conditions;
- an order confirmation, booking, quotation or specification;
- advertising or product descriptions that formed part of the transaction;
- delivery terms, guarantees, warranties or service levels; and
- any later variation, cancellation or settlement agreement.
Mark the clauses or statements that matter to the dispute. Do not include pages merely because they exist. A short note beside each document should explain what it proves and why it is relevant.
2. Invoices, payments and delivery records
Keep invoices, receipts, bank or card statements, payment confirmations, delivery tracking, collection records and refund attempts. These documents can establish the price, the date of payment, whether goods or services were supplied, and whether the other party has already paid part of the amount.
If you paid through a bank, card provider or platform, retain the relevant case reference and outcome. Payment evidence should support the figures in your claim rather than simply repeat them.
3. Messages, calls and complaints
Save emails, letters, online chat transcripts, text messages and platform messages in their original form where possible. Put them in date order and identify the sender and recipient. If a telephone call is important, create a short contemporaneous note stating the date, participants, main points and any promised action. A call log can show that contact occurred, but it may not prove what was said.
Include your formal complaint, the response, and any letter before action. If you need help structuring this stage, see the UK formal complaint letter toolkit and the complaint letter templates guide.
4. Photographs, video and inspection evidence
For damaged goods, defective work, property conditions or delivery disputes, take dated photographs from both a wide view and close range. Keep the original files and note when, where and by whom they were taken. Avoid editing an image in a way that changes the evidence. If the condition could change, record it promptly and keep a dated sequence.
An independent inspection or expert report may be useful where the cause, standard or cost of repair is genuinely disputed. Ask whether the report addresses the precise issue in the claim; a lengthy report that does not connect the technical opinion to the legal dispute may add cost without adding clarity.
5. Witness evidence
A witness statement should explain what the witness personally saw, heard or did. It is not a place to repeat speculation, arguments or facts obtained only from somebody else. Identify the witness, use numbered paragraphs, keep the account chronological, and refer to supporting documents by a consistent label.
Your own statement can explain the transaction and the steps you took to resolve it. Other witnesses may help with delivery, conversations, workmanship, inspection or the effect of an event. Check the court’s directions for requirements about statement format, deadlines and attendance.
6. Loss schedule and remedy
Prepare a simple calculation showing each amount claimed. Separate the principal loss from interest, court fees or other items where appropriate, and explain how every figure was calculated. Link each item to evidence such as an invoice, quotation, receipt or payment record.
Do not claim a round figure without an explanation. If you are claiming the cost of replacement or repair, keep evidence that the proposed cost is reasonable and that the work relates to the alleged breach. Update the calculation if the other party makes a payment or if a loss changes.
7. Chronological index
Create an index before assembling the documents. A practical format is:
- Document number;
- date;
- description;
- page numbers, if available; and
- the point the document supports.
A useful index is not a second argument. It is a map that allows the court and the other party to find the relevant material quickly.
What to redact or leave out
Remove irrelevant personal data, passwords, full payment-card details, unrelated medical information and private correspondence that does not assist the issue. Keep enough information to identify the transaction. Be careful with documents containing another person’s data: consider whether it is necessary and whether the court has given instructions about disclosure.
Do not delete inconvenient evidence. If a document is relevant but unhelpful, it may still need to be disclosed or addressed, depending on the court’s directions. Do not create misleading screenshots by omitting surrounding messages or dates.
Cadence and checkpoints
Treat the evidence file as a live record rather than a one-time task. Review it at these checkpoints:
- Before sending a letter before action: identify the contract, breach, loss and remedy, and check that the proposed figures are supported.
- When the other party replies: save the response, note which facts are admitted or disputed, and record any new documents or explanations.
- Before issuing a claim: check the relevant limitation position, correct party details, address for service and the current court process. The UK legal time limits guide can help you identify questions to investigate, but it is not a substitute for case-specific advice.
- After receiving court directions: create a deadline list for statements, documents, fees, hearing arrangements and any required form.
- Monthly while the dispute remains active: update the chronology, loss schedule, contact details and list of missing evidence.
- Before the hearing: read the file from the court’s perspective and check that every important assertion has a document or witness explanation behind it.
Keep at least two backups in secure locations. Use clear file names such as “2026-05-14-email-refund-request” rather than “final2-new”. Keep the original email or file metadata where practical, and record when a document was downloaded or exported.
How to interpret changes
New information should change your preparation only when it affects an issue the court must decide. For example, an admission about delivery may reduce the importance of tracking records, while a dispute about quality may make inspection photographs or expert evidence more important.
Separate facts from conclusions. “The parcel was marked delivered at 14:10” is a factual point supported by a tracking record. “The seller acted dishonestly” is a conclusion requiring careful evidence and may not be necessary to establish a straightforward contract claim. Concentrating on the issues in dispute usually produces a stronger, shorter file.
Check for contradictions as the file grows. Compare dates in invoices, messages, photographs and witness statements. If you find an error, correct it transparently and keep a note of the correction. A clear explanation is generally more useful than allowing an inconsistency to appear for the first time at a hearing.
Do not assume more evidence is better evidence. Irrelevant pages can hide the important documents and increase the time needed to understand the dispute. A focused chronological file, accurate loss schedule and concise witness evidence are usually more useful than an unindexed archive of every communication.
When to revisit
Revisit this checklist whenever the other party sends a substantive response, a payment is made, a new defect appears, a witness becomes unavailable, or the court issues directions. Review it at least monthly while the dispute is active, and again shortly before each procedural deadline or hearing.
At every review, ask:
- What facts are agreed and what facts remain disputed?
- Which document supports each important allegation?
- Has the loss figure changed, and can the change be evidenced?
- Have I preserved the original files and recorded the source?
- Have I removed irrelevant or unnecessarily sensitive material?
- Am I following the latest court directions and forms?
Before filing or attending court, assemble the final version in the order required by the directions, label it consistently, and keep a copy you can access easily. Check official court guidance for current filing requirements and deadlines, because these can change. If the claim is legally complex, involves a substantial sum, or raises limitation, expert or evidence-disclosure issues you do not understand, consider obtaining independent legal advice.
