Harper James is a full-service UK commercial law firm advising ambitious businesses on the laws of England and Wales. A letter before action, also called a letter of claim, sets out a proposed legal claim and gives the recipient a final opportunity to respond before proceedings begin.
Check the contract, applicable pre-action protocol and limitation period before writing. The letter should identify the parties, explain the relevant facts, state the legal basis of the claim, specify the remedy sought and attach or list the key documents. For a debt claim, include an accurate calculation of the principal, interest and any contractual charges.
Use a clear structure and avoid exaggerated language. State what happened in date order, identify the contractual term or duty relied upon, explain how the breach caused loss and set out the steps required to resolve the dispute. If money is claimed, show the calculation rather than using a rounded figure without explanation. Include a reasonable deadline for a full response, taking account of the relevant protocol and the complexity of the dispute. Further practical guidance can support research into the wider pre-action process.
Review the evidence, including contracts, invoices, emails, delivery records and meeting notes. Confirm that the correct legal entity and address are named, and check any contractual notice clause. Consider whether negotiation or mediation is appropriate, since the court expects parties to engage constructively with dispute resolution. A letter before action should not threaten steps that the claimant is unwilling or unable to take.
Record when the letter was sent and monitor the response. The recipient may admit the claim, propose payment, ask for more information or dispute liability. Assess each response against the evidence and the requested remedy. If no satisfactory response arrives, the next step may be court proceedings, a debt recovery route or another contractual remedy, subject to the relevant rules and limitation period.
