What Is a Letter Before Action?
A letter before action (also called a "letter before claim" or "letter of claim") is a formal letter sent to the other party in a dispute before you issue court proceedings. It is not optional — the Civil Procedure Rules (CPR) and their associated Pre-Action Protocols require parties to exchange information and attempt to resolve disputes before going to court.
If you issue proceedings without first sending a proper letter before action, the court may penalise you on costs — even if you win the case. The purpose is straightforward: courts are expensive and slow, and many disputes can be resolved through direct communication.
When Do You Need One?
A letter before action should be sent whenever you intend to take legal action and the dispute has not been resolved through informal communication. Common situations include:
Debt recovery: when someone owes you money and has not paid despite reminders.
Contract disputes: when goods or services have not been delivered as agreed.
Consumer complaints: when a retailer or service provider has failed to resolve a complaint through their internal process.
Property disputes: when a landlord has failed to carry out repairs or return a deposit.
Professional negligence: when a professional (solicitor, accountant, surveyor) has caused you loss through inadequate service.
What Must It Contain?
The specific content depends on the type of dispute, but the CPR Pre-Action Conduct Practice Direction sets out general requirements that apply to all claims:
Your details: full name, address, and contact information. If you are represented by a solicitor, their details.
The other party's details: full name (or registered company name) and address.
A clear summary of the facts: what happened, when, and who was involved. Be factual and specific — dates, amounts, and references to relevant documents.
The basis of your claim: what legal right or obligation has been breached. You do not need to cite specific legislation at this stage, but you should explain why you believe the other party is at fault.
What you want: the specific remedy you are seeking — a sum of money, specific performance, repairs, an apology, or other resolution. If you are claiming a monetary sum, state the amount and how it is calculated.
Key documents: list (or enclose copies of) the main documents you rely on — contracts, invoices, correspondence, photographs.
A reasonable deadline: give the other party a specific period to respond. The general Pre-Action Protocol typically requires 14 days for a simple debt claim, or up to three months for more complex disputes. If you give an unreasonably short deadline, the court may view this unfavourably.
A statement about ADR: you should state that you are willing to consider alternative dispute resolution (mediation or negotiation) before issuing proceedings. Courts take a dim view of parties who refuse to engage in ADR.
Tone and Approach
A letter before action should be firm, factual, and professional. It is not a vent for frustration. Avoid emotional language, personal attacks, or threats beyond the legitimate statement that you intend to issue proceedings if the matter is not resolved.
The letter may be shown to a judge. Write it as though a judge will read it — because they might. A measured, well-structured letter creates a far better impression than an angry demand.
What Happens After You Send It?
If they respond positively: negotiate a resolution. Many disputes are settled at this stage, saving both parties the cost and stress of court proceedings.
If they respond with a defence: consider whether their points have merit. If the dispute remains unresolved, propose mediation before escalating to court.
If they do not respond: wait until your stated deadline has passed, then you may issue proceedings. Keep proof that the letter was sent (recorded delivery receipt, email read receipt, or a copy of the letter with proof of posting).
Specific Pre-Action Protocols
The CPR includes dedicated Pre-Action Protocols for certain types of claims. These set out additional requirements beyond the general practice direction:
Personal Injury Protocol: requires a letter of claim with specific medical details and a response period of 21 days (acknowledgment) plus three months (full response).
Professional Negligence Protocol: requires a preliminary notice, then a detailed letter of claim, with a response period of three months.
Housing Disrepair Protocol: requires a detailed letter describing the disrepair, with inspection arrangements and a response period of 20 working days.
Debt Claims Protocol: applies to businesses claiming payment from individuals, with specific information requirements and a 30-day response period.
Using Technology to Prepare
Structuring the facts of your dispute before drafting a letter before action helps ensure you include everything the court expects. The Ratio Matter Intake guides you through a structured questioning process that separates facts from opinions, builds a chronological timeline, identifies the relevant legal category, and produces a matter file. This structured output can inform your letter before action — or be shared directly with a solicitor who can draft the letter on your behalf.
Frequently Asked Questions
Is a letter before action legally required?
The CPR Practice Direction on Pre-Action Conduct requires parties to exchange sufficient information to understand each other's position and attempt to resolve the dispute before issuing proceedings. While not sending a letter before action does not prevent you from issuing a claim, the court may impose adverse costs orders if you fail to follow pre-action requirements.
Can I send a letter before action by email?
Yes, email is generally acceptable, but recorded delivery post provides stronger proof of delivery. If you send by email, request a read receipt and follow up with a hard copy if you do not receive a response. The key is being able to demonstrate that the letter was sent and received.
What if I cannot afford a solicitor to write the letter?
You do not need a solicitor to write a letter before action. Many people write their own, and courts do not penalise unrepresented parties for imperfect drafting. What matters is that the letter is factual, clear about what you want, gives a reasonable deadline, and mentions willingness to use ADR. Free legal advice from Citizens Advice or a local law centre can help you check your letter before sending it.
How long should I wait for a response?
The general rule is 14 days for straightforward claims and up to three months for complex matters. If a specific Pre-Action Protocol applies to your type of claim, follow its prescribed timeframes. Do not issue proceedings before your stated deadline has expired — doing so may attract adverse costs consequences.
