What Is a Letter Before Action?

What is a Letter Before Action?
A Letter Before Action is the last formal step a creditor usually takes before issuing a court claim. It puts the debtor on clear notice of the amount claimed, the basis for it, and the consequences of not responding. The courts expect parties to try to resolve a dispute before litigating, and an LBA is the standard way to show that you gave the other side a fair opportunity to pay or reply.
The same document is often called a "letter before claim". Whatever the name, its purpose is the same: to set out the claim properly, exchange information, and avoid court where possible.
What does a Letter Before Action include?
A well-prepared LBA for a B2B debt generally covers the same core points:
| Element | What it sets out |
|---|---|
| The parties | Who is owed the money and who owes it. |
| The debt | The amount claimed and what it relates to (invoice numbers, dates, the contract or order). |
| Interest and costs | Any statutory or contractual interest and fixed compensation being claimed, with the basis stated. |
| Evidence | The key documents relied on — invoices, the agreement, delivery or acceptance records, prior reminders. |
| The deadline | A clear date by which to pay or respond. |
| Next steps | That court proceedings may follow if there is no satisfactory response by the deadline. |
Does the same deadline apply to every debtor?
No — and this is a common myth. People often assume the 30-day reply window in the Pre-Action Protocol for Debt Claims applies to every unpaid debt. It does not. That protocol applies only where the debtor is an individual, including a sole trader. Where the debtor is a company or other business entity, the protocol does not apply; instead the general Practice Direction on Pre-Action Conduct and Protocols governs the position.
| Debtor type | What applies | Typical response time |
|---|---|---|
| Individual or sole trader | Pre-Action Protocol for Debt Claims | 30 days to respond (with prescribed information and a reply form) |
| Company / business entity | Practice Direction on Pre-Action Conduct and Protocols | A reasonable period — commonly 14 days or more, depending on the facts |
Getting this distinction right matters. Sending a company debtor a letter built around the 30-day debt protocol, or sending an individual a letter that ignores the protocol's prescribed information, can both undermine the process. Check who the debtor actually is before deciding which rules apply.
How long must the debtor be given to respond?
For an individual or sole trader under the Pre-Action Protocol for Debt Claims, the debtor is generally given 30 days to respond, and specific information and a reply form must accompany the letter. For a company, the Practice Direction on Pre-Action Conduct expects a reasonable period rather than a fixed number — often 14 days or more, depending on the size and complexity of the claim. Allowing a fair, clearly stated deadline is the safe approach in either case.
What happens after a Letter Before Action?
If the debtor pays, the matter ends. If they dispute the debt or propose to pay by instalments, the parties are expected to exchange information and try to resolve or narrow the dispute. If the deadline passes with no satisfactory response, the creditor may decide to start a court claim — but issuing a claim is a separate decision with its own costs, risks, and time limits, and many creditors take advice before that step.

Frequently asked questions
Is a Letter Before Action legally required?
There is no single statute that says you must send one in every case, but the courts expect parties to behave reasonably and try to resolve a dispute before litigating. For an individual or sole trader debtor, the Pre-Action Protocol for Debt Claims sets out a structured process; for companies, the Practice Direction on Pre-Action Conduct applies. Skipping a proper letter can have consequences if a claim later reaches court.
How long must I wait after sending one?
It depends on the debtor. For an individual or sole trader under the Pre-Action Protocol for Debt Claims, generally 30 days. For a company under the Practice Direction on Pre-Action Conduct, a reasonable period — commonly 14 days or more depending on the facts. Always state a clear deadline in the letter.
Can I write my own Letter Before Action?
Yes — a creditor can prepare and send its own letter, and WolfX helps you organise the evidence and draft an evidence-backed letter. This is general information, not legal advice; for a disputed, high-value, or complex debt you may wish to take advice before issuing court proceedings.
