What Is a Letter Before Action? The Debt Letter So Good, the Debtor Paid
Quick answer
A letter before action — also called a letter of demand or formal notice — is the last formal warning to a debtor before going to court. It states who owes what and why, sets a clear deadline to pay or respond, and explains what happens if they don't. In many countries courts expect it before a claim is filed, and it often gets you paid without going to court.
The story in the video
Our lawyer cooks the perfect letter before action in a Michelin-star kitchen, with Gerald the goose as head chef, and serves it to Bruno — flambéed. The letter is so good that Bruno pays. Then comes the plot twist: he hires us to write his own.
The recipe: 5 ingredients of a good letter before action
- Who owes what: the exact amount and the full legal names of both parties.
- Why: the invoice, contract or order behind the debt, with dates and references.
- A clear deadline to pay or respond — often 14 to 30 days.
- What happens next: court proceedings, legal costs and interest if they ignore it.
- Proof of receipt: tracked post, or email with a delivery or read receipt.
Keep the tone firm, factual and polite. A letter that sounds angry is easier to ignore than one that sounds ready.
Why courts expect this letter first
In many countries, a court wants to see that the debtor was warned and given a chance to pay or dispute the claim before proceedings started. In England and Wales, for example, the rules on pre-action conduct expect parties to exchange information and consider settlement, and courts can penalise a party who skips this step, including through costs. In other countries a formal notice can matter for when the debtor is legally in default and when interest starts to run.
How long should the deadline be?
Long enough to be reasonable, short enough to create urgency. For straightforward business debts, 14 days is common; claims against individuals or sole traders often require longer, such as 30 days under specific rules. Always check local requirements — and never set a deadline you don't intend to act on.
Common mistakes to avoid
- Getting the debtor's legal name or the amount wrong.
- Threatening action you won't take — it destroys your credibility.
- Forgetting to attach the invoice and key documents.
- Sending it to the wrong address or person, with no proof of delivery.
- Missing statutory interest and recovery costs you are entitled to.
