What Is a Letter Before Action?

A Letter Before Action (LBA) — also called a Letter Before Claim — is a formal written notice you send to the person or business you intend to sue. It is required under the UK Pre-Action Protocols before you can file a court claim.

The letter puts the other party on notice that legal proceedings will follow if they do not pay or resolve the dispute within the deadline you set.

⚖️ Legal requirement: Courts expect parties to follow the Pre-Action Protocol before issuing a claim. Failure to send an LBA can result in cost penalties even if you win.

What Must a Letter Before Action Include?

  1. Your full name and address — as claimant
  2. Defendant's full name and address — use the registered address for companies
  3. Clear description of the dispute — what happened, when, and what was agreed
  4. The amount claimed — principal debt plus any interest and fees
  5. Supporting documents referenced — invoices, contracts, emails
  6. A payment deadline — typically 14 days for businesses, 30 days for individuals
  7. What happens if no response — court proceedings will be issued
