Pre-Litigation Letter Checklist: What to Include Before You Escalate

Published July 2026 • MyLegalLetters Editorial • 7 min read • General information only

A good pre-litigation letter does not shout. It sets out the problem, shows what you can prove, says what you want, and gives the other side a clear chance to respond. Done properly, it can make the next step easier to judge. Done badly, it can create confusion or say more than you meant to say.

Use this checklist to keep the letter clear, measured and useful.

Important: This article is general information, not legal advice. If the matter is urgent, high-value, complex, or involves safety, discrimination, dismissal, eviction or debt enforcement, speak to a qualified solicitor before sending anything.

1. Decide what you actually want

Before writing, be specific about the outcome. "Sort it out" is hard to answer. A clear request is easier to accept, refuse or negotiate.

Common outcomes

Refund, repair or replacement
Payment of an amount owed
Correction of a record or statement
Return of property or deposit
A written response by a set date
Confirmation that a behaviour will stop

2. Stick to facts you can support

Write the facts as if someone calm will read them later. Keep dates, amounts, names and events accurate. If you are not sure of something, say so plainly or leave it out.

What happened?
When did it happen?
Who was involved?
What agreement, order, payment or term is relevant?
What has happened since?

3. Attach or list your evidence

You do not need to dump every screenshot into the letter. But you should point to the evidence you hold and keep it organised.

Contracts, terms, invoices, receipts or order confirmations
Emails, messages, call logs or complaint references
Photos, videos, statements or inspection notes
Bank records or payment confirmations
A simple timeline if the sequence matters

4. Make the request easy to answer

Ask for one main outcome and, if needed, one fallback. Too many demands can make the letter feel unfocused.

Example shape: "Please refund £X by [date]. If you do not agree, please explain why in writing by the same date."

5. Give a reasonable deadline

A deadline should be clear and realistic. What is reasonable depends on the issue, the amount, the evidence and whether the other side needs time to investigate. Avoid arbitrary threats or same-day demands unless there is a genuine reason.

6. Keep the tone formal, not furious

You can be firm without being personal. Avoid insults, speculation about motives, and legal threats you do not intend to follow through. A calm letter is usually easier to take seriously.

Swap this for that

Instead of: "You scammed me."
Try: "The item supplied did not match the description."
Instead of: "You have until Friday or else."
Try: "Please respond by Friday 14 August 2026."
Instead of: "Everyone knows you do this."
Try: "I have attached the records I rely on."

7. Say what happens next, carefully

If you mention next steps, keep them accurate and proportionate. For example: "If we cannot resolve this, I may consider formal complaint routes, mediation, or legal advice." Do not pretend court action is certain if it is not.

8. Keep proof of sending

Use a method you can evidence later. Save the final letter, attachments, sending receipt, delivery confirmation and any reply. If the matter escalates, that record can save time.

9. Know when not to send it yourself

Some disputes need advice before you put anything in writing. Get help if the issue involves a large amount, strict deadlines, employment rights, housing security, regulated financial matters, personal data, allegations of dishonesty, or anything already close to court.
