A Letter Before Action (LBA), also known as a Letter Before Claim, is the formal written notification that a potential claimant is required to send to a potential defendant before commencing civil litigation in England and Wales. It is a mandatory step in the pre-action phase of civil proceedings and is governed by Practice Direction — Pre-Action Conduct and Protocols under the Civil Procedure Rules 1998 (CPR), as well as by specific Pre-Action Protocols applicable to particular categories of claim.

Practice Direction — Pre-Action Conduct and Protocols sets out the overriding objectives of the pre-action regime: to encourage early exchange of information, to promote the settlement of disputes without recourse to litigation, to support the efficient management of proceedings if litigation does prove necessary, and to reduce the cost and delay associated with civil justice. The Pre-Action Protocol regime reflects the judiciary's strong preference for settlement and its expectation that parties will behave reasonably and proportionately before and during proceedings.

A Letter Before Action is distinct from a Letter Before Action for Debt Claims (governed by the Pre-Action Protocol for Debt Claims, which came into force on 1 October 2017 and imposes specific requirements for debt recovery claims including a minimum 30-day response period). For other civil claims — including breach of contract, negligence, misrepresentation, nuisance, and unjust enrichment — the general Practice Direction applies, and the claimant must send a letter that clearly identifies the nature of the claim, the legal basis, the remedies sought, and the documents relied upon, and gives the defendant a reasonable time to respond.

A properly drafted Letter Before Action serves several important functions. It alerts the defendant to the nature of the claim and gives them an opportunity to settle or compromise before proceedings are issued. It demonstrates to the court that the claimant has acted reasonably and proportionately. It preserves the claimant's position on costs, as a court may impose costs sanctions on a claimant who fails to comply with the pre-action requirements. It identifies the key documents and evidence at an early stage, which can help to clarify both parties’ understanding of the dispute. And it provides a formal record that the claimant gave the defendant a fair opportunity to resolve the matter without litigation.

The Supreme Court’s decision in Churchill v Merthyr Tydfil County Borough Council [2023] UKSC 45 significantly strengthened the court's power to stay proceedings and order parties to engage in ADR before litigation continues. A Letter Before Action that includes an ADR proposal therefore serves an important practical and strategic function, potentially saving both parties the considerable cost and delay of court proceedings.

A Letter Before Action is needed whenever a person or business in England and Wales is intending to bring a civil claim in the County Court or the High Court and has not already reached a negotiated settlement with the other party. It is the mandatory final step before litigation and should be sent after informal attempts to resolve the dispute have been exhausted.

Breach of contract claims are the most common scenario. Where one party has failed to perform its contractual obligations — whether by failing to pay for goods or services, failing to deliver contracted works on time or to the agreed standard, wrongfully terminating a contract, or breaching a confidentiality or restrictive covenant — a Letter Before Action is needed before a County Court claim can be issued. The letter must identify the contract, the specific breaches alleged, and the financial or other remedies sought.

Negligence claims, whether in a professional, commercial, or property context, require a Letter Before Action before proceedings. Claims against solicitors, surveyors, accountants, architects, engineers, financial advisers, or other professionals should comply with the relevant sector-specific Pre-Action Protocol where one exists. For general negligence claims, the Practice Direction applies and the letter must set out the duty of care alleged, the breach, and the resulting loss.

Construction disputes are a frequently litigated area of English law. Disputes between employers and contractors over defects, delays, interim payments, and final account settlements require a Letter Before Action before county court proceedings. Many construction contracts also include adjudication clauses, and the letter should consider whether adjudication under the Housing Grants, Construction and Regeneration Act 1996 is appropriate.

Property disputes, including boundary disputes, rights of way, easements, and covenants, require a Letter Before Action before a Part 7 claim or a Part 8 application is made. Disputes between landlords and tenants over disrepair, service charges, or dilapidations should comply with the Pre-Action Protocol for Housing Disrepair Claims where applicable.

Misrepresentation claims under the Misrepresentation Act 1967 or at common law require a Letter Before Action before proceedings are issued. The letter must identify the specific representations made, the facts that make them false or misleading, and the loss caused as a result of reliance on the representations.

Personal injury and road traffic accident claims have their own specific Pre-Action Protocols and are typically handled by specialist solicitors. This template is not designed for personal injury or clinical negligence claims, which should use the specific protocols for those claim types.

A valid and effective Letter Before Action for general civil claims in England and Wales must contain several key elements to comply with Practice Direction — Pre-Action Conduct and Protocols and to protect the claimant's position on costs.

Clear identification of the parties is essential. The letter must identify the full legal name and address of the claimant and the defendant. If the claimant is represented by solicitors, the letter should be written on the solicitors' headed notepaper and should identify the firm’s name, address, and the fee-earner with conduct of the matter.

A concise and factual summary of the background is required. The letter must give the defendant sufficient information to understand the nature of the claim and to investigate it. The factual summary should be chronological, accurate, and focused on the matters material to the claim. Exaggeration or inaccuracy in the Letter Before Action can undermine the claimant’s credibility in any subsequent proceedings.

The legal basis of the claim must be identified. This means identifying the specific legal obligation that has been breached (whether a contractual term, a statutory duty, or a common law duty of care) and, where appropriate, citing the relevant statute or case law. For breach of contract claims, the specific contractual terms relied upon should be identified. For negligence claims, the duty of care, breach, and causation should be addressed.

The remedies sought must be specified. The letter must state whether the claimant is seeking damages, specific performance, an injunction, rescission, or another remedy. Where damages are claimed, a breakdown of the losses claimed should be provided. This allows the defendant to assess the value of the claim and decide whether to settle or defend.

The documents relied upon must be identified. Practice Direction — Pre-Action Conduct and Protocols requires the claimant to list the key documents and, where practicable, to provide copies. Early disclosure of documents facilitates settlement and demonstrates the claimant’s transparency.

The response period must be clearly stated. For most civil claims, 14 days is appropriate for a straightforward case. For complex claims involving large sums or technical issues, a longer period (up to three months) may be warranted. The response deadline date should be expressly stated.

An ADR proposal is strongly recommended. Since Churchill v Merthyr Tydfil County Borough Council [2023] UKSC 45, courts in England and Wales have confirmed authority to order parties to engage in ADR. Including an ADR proposal in the Letter Before Action demonstrates good faith and may provide costs protection if the defendant unreasonably refuses to engage.

A limitation period warning should be included where the limitation period is approaching. This alerts the defendant to the risk that proceedings may need to be issued without waiting for the full response period, and demonstrates that the claimant has acted reasonably in sending the letter at the earliest opportunity.
