Pre-Action Protocols: What to Do Before Starting a Claim

Which CPR pre-action protocol applies to your dispute, what a letter before claim must contain, response timescales, and the sanctions for non-compliance.

Quick answer

Pre-action protocols are the steps the Civil Procedure Rules expect you to complete before issuing a civil claim in England and Wales. Specific protocols cover disputes such as personal injury, clinical disputes, construction, defamation, professional negligence, judicial review, housing disrepair, possession claims and debt claims by businesses against individuals; where none applies, the Practice Direction on Pre-Action Conduct and Protocols governs. In outline: send a letter before claim setting out the basis of the claim, the facts and what you want; allow the prescribed response time (14 days in a straightforward case, up to 3 months in a very complex one — 30 days under the debt protocol, 21 days plus up to 3 months' investigation in personal injury); exchange key documents; and genuinely consider ADR. Non-compliance can lead to a stay of proceedings, adverse or indemnity costs orders, and interest penalties of up to 10% above base rate.

Overview

Before you issue a civil claim in England and Wales, the Civil Procedure Rules expect you to follow a pre-action protocol for your type of dispute — or, if none applies, the Practice Direction on Pre-Action Conduct and Protocols. The purpose is to exchange enough information to understand each other's position, try to settle without proceedings, and consider ADR. Skipping these steps is not a technicality: the court will take non-compliance into account when giving case management directions and when making orders for costs.

Who Can Use This Process

  • You are contemplating civil court proceedings in England and Wales
  • A specific protocol applies to your dispute type (for example personal injury, clinical disputes, construction, defamation, professional negligence, judicial review, housing disrepair, possession claims or debt claims)
  • If no specific protocol applies, the Practice Direction on Pre-Action Conduct and Protocols still governs what the court expects before proceedings

Step-by-Step Process

1

Identify Which Protocol Applies

Check the list of protocols in force before doing anything else. They include Personal Injury, Resolution of Clinical Disputes, Construction and Engineering, Defamation, Professional Negligence, Judicial Review, Disease and Illness, Housing Disrepair, Possession Claims by Social Landlords, Possession Claims for Mortgage Arrears, Dilapidation of Commercial Property and Low Value Personal Injury claims — plus the Pre-Action Protocol for Debt Claims for businesses chasing debts from individuals. Each protocol sets its own letter contents and timetable.

Practical Tips
  • The Debt Claims protocol applies to any business (including sole traders and public bodies) claiming payment of a debt from an individual, including a sole trader — but not to business-to-business debts unless the debtor is a sole trader
  • If your dispute type has no protocol, follow the general Practice Direction instead
2

Understand What the Court Expects

Whether under a protocol or the Practice Direction, before commencing proceedings the court will expect the parties to have exchanged sufficient information to understand each other's position, make decisions about how to proceed, try to settle the issues without proceedings, consider ADR, support efficient case management and reduce the costs of resolving the dispute.

Practical Tips
  • Keep a paper trail of each pre-action step — it is your protection on costs later
  • Only take reasonable and proportionate steps: the protocol must not be used as a tactical device
3

Send a Compliant Letter Before Claim

Under the Practice Direction, the claimant's letter should include the basis on which the claim is made, a summary of the facts, what the claimant wants from the defendant and, if money, how the amount is calculated. Protocol-specific letters go further — for example, a debt Letter of Claim must state the amount of the debt, whether interest or charges are continuing, and enclose the protocol's Information Sheet, Reply Form and a Financial Statement form; a judicial review letter must give the date and details of the decision challenged, a clear summary of the facts and the legal basis for the claim.

Practical Tips
  • Use the standard-format annexes where a protocol provides them
  • Date the letter properly and send it promptly — protocol response periods run from it
4

Allow the Right Response Time

Response periods vary by regime. Under the general Practice Direction the defendant should respond within 14 days in a straightforward case and no more than 3 months in a very complex one. Under the Debt Claims protocol the debtor has 30 days to reply before proceedings may be started. In personal injury claims the defendant must reply within 21 calendar days identifying their insurer, then has a maximum of three months from acknowledgment to investigate and state whether liability is admitted. In judicial review, defendants should normally respond within 14 days.

Timeframe: 14 days to 3 months depending on the protocol
Practical Tips
  • Diarise the protocol deadline the day you send the letter
  • In judicial review, never let the protocol exchange eat your 3-month filing window — the protocol does not affect the rule 54.5(1) time limit
5

Exchange Key Documents

Pre-action expectations include the parties disclosing key documents relevant to the issues in dispute. Under the Debt Claims protocol this is explicit: if the debtor requests a document or information, the creditor must provide it, or explain why it is unavailable, within 30 days of receipt of the request.

Practical Tips
  • Disclose the documents that hurt as well as help — the court will see selective disclosure as non-compliance
  • Ask early for the documents you need from the other side, in writing
6

Consider ADR Seriously

Litigation should be a last resort. The parties should consider whether negotiation or some other form of ADR might enable them to settle their dispute without commencing proceedings — options include mediation, arbitration, early neutral evaluation and ombudsman schemes. A party's silence in response to an invitation to participate in ADR, or a refusal to participate, might be considered unreasonable by the court and could lead to an order to pay additional court costs.

Practical Tips
  • Put your ADR proposal in writing so you can evidence it later
  • If you decline ADR, record your reasons at the time
7

Take Stock Before Issuing

When the protocol steps are complete but the dispute remains, review your position before issuing. Costs incurred in complying should be proportionate — disproportionate costs will not be recoverable as part of the costs of the proceedings. Under the Debt Claims protocol, the creditor should not start proceedings less than 30 days from receipt of the completed Reply Form, or 30 days from providing any documents requested by the debtor, whichever is later.

Timeframe: Debt claims: at least 30 days after a completed Reply Form
Practical Tips
  • Re-run the numbers: the claim value, the fees, the realistic recovery
  • Check limitation — pre-action compliance never justifies missing a limitation deadline
8

Know the Sanctions for Non-Compliance

If a dispute proceeds to litigation, the court will expect the parties to have complied with a relevant protocol or the Practice Direction, and will take non-compliance into account when giving directions and when making costs orders. The court may stay proceedings while steps are taken to comply, order the party at fault to pay costs (or costs on the indemnity basis), deprive a non-compliant claimant of interest, or award interest against a non-compliant defendant at up to 10% above base rate.

Practical Tips
  • Courts look at substance, not technicalities — minor infringements rarely attract sanctions, wholesale failure does
  • If the other side has ignored the protocol, say so in your directions questionnaire and costs submissions

Important Warnings

A pre-action protocol or the Practice Direction must not be used as a tactical device to secure an unfair advantage — only reasonable and proportionate steps should be taken

Disproportionate pre-action costs will not be recoverable as part of the costs of the proceedings

The judicial review protocol does not affect the strict rule 54.5(1) time limit for filing a claim

Silence in response to an ADR invitation, or refusal to participate, may be treated as unreasonable and punished in costs

Frequently asked questions

What is a pre-action protocol?
It is a code of conduct the court expects parties to follow before starting proceedings for a particular type of dispute. The aim is that the parties exchange sufficient information to understand each other's position, try to settle without proceedings, consider ADR, and reduce the costs of resolving the dispute. Where no specific protocol exists, the Practice Direction on Pre-Action Conduct and Protocols applies.
Which disputes have their own protocol?
Protocols in force include Personal Injury, Resolution of Clinical Disputes, Construction and Engineering, Defamation, Professional Negligence, Judicial Review, Disease and Illness, Housing Disrepair, Possession Claims by Social Landlords, Possession Claims for Mortgage Arrears, Dilapidation of Commercial Property and Low Value Personal Injury claims, plus the Debt Claims protocol for businesses claiming debts from individuals.
How long do I have to give the other side to reply to a letter before claim?
Under the general Practice Direction, the defendant should respond within 14 days in a straightforward case and no more than 3 months in a very complex one. Specific protocols set their own periods: 30 days for debt claims, 21 calendar days to acknowledge (then up to three months to investigate) in personal injury, and normally 14 days in judicial review.
What happens if the other side simply ignores my letter?
You can issue proceedings once the relevant response period has passed — under the debt protocol, for example, if the debtor does not reply within 30 days of the date on the Letter of Claim the creditor may start court proceedings. The other side's failure to respond is itself non-compliance the court can take into account on directions and costs.
What are the sanctions for ignoring a pre-action protocol?
The court will take non-compliance into account when giving case management directions and making costs orders. It can stay the proceedings while compliance steps are taken, order the party at fault to pay costs or costs on the indemnity basis, deprive a non-compliant claimant of interest on damages, or award interest against a non-compliant defendant at up to 10% above base rate. Courts focus on substantial compliance rather than minor or technical infringements.
Do I really have to consider mediation or ADR?
Yes — litigation should be a last resort, and the parties should consider whether negotiation or another form of ADR (mediation, arbitration, early neutral evaluation or an ombudsman scheme) could settle the dispute. Silence in response to an ADR invitation or a refusal to participate might be considered unreasonable and can lead to the court ordering that party to pay additional costs.
