Written by A pre-action letter is not a formality. It is the point at which a potential claimant explains the dispute, identifies the remedy sought, gives the other side a fair opportunity to respond, and shows the court that litigation is being treated as a last resort. For litigants in person, getting this stage right can narrow the issues, improve settlement prospects and reduce avoidable costs risk.
Publication snapshot
- A pre-action letter is often called a letter before action or letter of claim.
- The correct process depends on whether a specific pre-action protocol applies to the type of dispute.
- If no specific protocol applies, the Practice Direction – Pre-Action Conduct and Protocols provides the general framework.
- A good letter explains the facts, legal basis, remedy sought, key documents and proposed response deadline.
- Pre-action conduct does not stop limitation running, so urgent claims need separate limitation review.
What is a pre-action protocol letter?
A pre-action protocol letter is a formal letter sent before court proceedings are started. Depending on the type of dispute, it may be called a letter before action, letter of claim, pre-action protocol letter, or pre-action letter.
Its purpose is to tell the proposed defendant what the claim is about, why the claimant says they are legally responsible, what remedy is being sought, what documents or evidence support the claim, and what response is required before proceedings are issued.
The letter should not be written as a threat, a grievance dump or a tactical ambush. It should be clear enough for the other side to understand the case and decide whether to admit it, dispute it, ask for information, make an offer, suggest ADR, or explain why the claim is not accepted.
Why pre-action conduct matters
The court expects parties to exchange enough information before proceedings to understand each other’s position, make informed decisions, try to settle, consider ADR, support efficient case management and reduce the cost of resolving the dispute.
For a litigant in person, this stage is especially important. A properly prepared letter can show that the claim is serious, evidence-based and proportionate. It can also expose weaknesses before issue, which may prevent a claim being started on the wrong basis.
Poor pre-action conduct can have consequences. The court may take non-compliance into account when managing the case and when deciding costs. In suitable cases, sanctions may include costs orders, indemnity costs, a stay of proceedings, or interest consequences.
The parties should normally exchange information, consider ADR and follow the relevant protocol or Practice Direction before issuing.
Pre-action steps do not extend statutory limitation periods. If time is short, urgent legal advice may be needed before waiting for a response.
Step one: identify the correct protocol
Before drafting the letter, identify whether a specific pre-action protocol applies. Examples include personal injury, clinical disputes, professional negligence, construction and engineering, defamation, housing disrepair, possession claims, judicial review and certain low-value injury claims.
The correct protocol matters because different claims may require different information, different documents, different forms, different response times and different conduct before issue.
Where no specific protocol applies, use the general Practice Direction – Pre-Action Conduct and Protocols. That does not mean “no rules”. It means the parties should still act proportionately, exchange enough information, disclose key documents, consider ADR and give a reasonable time for response.
The common LiP trap
-
1
The claimant sends a generic 14-day letter without checking whether a specialist protocol applies.
-
2
The letter omits documents, calculation, legal basis or the information required by the relevant protocol.
-
3
The defendant says the letter is defective and asks for more time or more information.
-
4
If proceedings are issued too quickly, the court may later treat the pre-action stage as unreasonable or incomplete.
Step two: include the essential contents
A pre-action letter should be structured and easy to answer. It should identify the parties, the dispute, the remedy sought and the response required.
Basic details
- Your name, address, email address and telephone number.
- The proposed defendant’s full name and postal address.
- The date of the letter and the method of sending.
- A clear heading, such as “Letter before claim” or “Pre-action protocol letter before claim”.
- Any relevant reference numbers, account numbers, contract numbers or property address.
Claim details
- A concise chronology of the key events.
- The legal or contractual basis of the claim, in plain terms.
- The facts that are said to be admitted, disputed or evidenced by documents.
- The remedy sought, including money, action, apology, correction, repair or other outcome.
- If money is claimed, a clear calculation showing how the figure has been reached.
Avoid overloading the letter with every grievance. The better approach is to identify the claim, the facts relied on, the documents that matter and the remedy required. If the case later goes to court, a clear pre-action letter will usually be more useful than a long emotional account.
Step three: evidence, ADR and deadlines
Attach copies of the key documents. Do not send originals unless there is a specific reason and you have kept copies. Documents might include contracts, invoices, receipts, emails, letters, photographs, expert reports, complaint correspondence, screenshots or account statements.
The letter should also invite the other side to consider ADR. ADR may include negotiation, mediation, early neutral evaluation, an ombudsman route, or another suitable process. The court may later ask what steps were taken to consider settlement and ADR before proceedings.
The response deadline should be realistic. A simple debt, invoice or straightforward contractual dispute may justify a shorter deadline. A complex professional negligence, construction, medical or document-heavy claim may require much longer. A rigid 14-day deadline is not appropriate for every case.
Step four: send it properly and keep records
Send the letter in a way that gives reliable proof. Postal service may be appropriate, but recorded or registered delivery can sometimes create practical problems if the recipient refuses or fails to sign for it. In many cases, first-class post with a certificate of posting, plus email where appropriate, is safer than relying on one method only.
Check any contract, previous correspondence, protocol, court rule or known solicitor details before choosing the address and method. If the proposed defendant has solicitors on the record for the dispute, consider whether the letter should be sent to them as well as, or instead of, the proposed defendant.
Keep a complete bundle: the signed letter, enclosures, email copy, proof of posting, delivery evidence, read receipts if available, and any response. Create a simple index so you can show later what was sent, when, and to whom.
What happens after the letter is sent?
The defendant may admit the claim, dispute it, ask for further information, request documents, make an offer, propose ADR, raise a counterclaim, or ignore the letter. Each response should be assessed calmly against the evidence and the legal basis of the claim.
If the dispute is not resolved, review the papers before issuing. Ask whether the claim is still properly formulated, whether the right defendant has been identified, whether limitation is safe, whether ADR has been considered, whether key documents have been exchanged, and whether the remedy sought is realistic.
If proceedings are necessary before the pre-action stage is complete because limitation is about to expire or urgent relief is required, consider asking the court to stay the proceedings while the parties complete the relevant pre-action steps.
If the response narrows the dispute or opens a realistic negotiation, it may be better to pursue resolution before issuing.
If the claim remains disputed and the evidence supports proceedings, the pre-action record should help define the claim and issues.
A simple letter before claim structure
The following structure can be adapted, but it should not be used mechanically. Check the relevant protocol first.
- Sender details: name, address, email and telephone number.
- Recipient details: proposed defendant’s full name, address and reference details.
- Heading: “Letter before claim” or the protocol-specific heading.
- Introduction: state that the letter is sent before intended civil proceedings.
- Background: set out the key facts in chronological order.
- Legal basis: identify the contract, duty, representation, statute or other basis relied on.
- Remedy sought: say what you want and, if money is claimed, how it is calculated.
- Documents: list the documents enclosed and any documents requested from the other side.
- ADR: invite negotiation, mediation or another suitable process.
- Response deadline: give a protocol-compliant or otherwise reasonable deadline.
- Next step: state that proceedings may be issued if the dispute is not resolved.
- Signature and enclosures: sign the letter and list every enclosure.
A good letter before claim is firm, factual and proportionate. It should show that the claimant is ready to litigate if necessary, but also ready to resolve the dispute without court proceedings if that can be done fairly.
