Letter before action

  • Civil Procedure Rules compliant
  • Includes your legal right to interest
  • Customisable to your circumstances

This letter before action (also known as a letter of claim) is designed to help if you:

  • want to threaten to sue another business that owes you money; or
  • want to sue an individual who owes you money (it is suitable for a straightforward debt claim against a consumer or a sole trader who has failed to pay your invoices); or
  • are thinking of suing a person or business for anything other than money they owe you. For example, if a supplier sent you the wrong items, or a courier service that you use damaged some of your goods in transit, you might want to sue them for compensation.

You must usually write a letter before action or letter of claim to warn the person that you intend to start a legal claim against them, and give them an opportunity to explain themselves or settle the matter with you, eg by paying up.

It gives the other business fair warning of your intentions and increases your chances of getting paid or getting a remedy without having to resort to expensive legal action.

If you don’t send a formal letter before action to the other side before starting a claim, you run the risk of being penalised by the court if you do go on to make a claim. For example, you might not be allowed to get your legal costs paid by the other side even if you win.

You can also purchase this document as part of the Small claims toolkit.

Q&A

  • When should I use this document?

    Use this letter before action if:

    • your business is owed money by another business and you want to warn them that you are considering suing them for what they owe; or

    • you want to threaten legal action against a private individual or a sole trader who has failed to pay your invoices; or

    • you want to sue a person or business for anything other than a debt. For example, if a freelancer or consultant’s services have fallen short of what was agreed, you may want to sue them for compensation if it has cost your business money.

    You do not have to wait until you have exhausted all other options before you use this letter before action, but remember that it is a serious thing to threaten legal action so this should not be your first step in trying to encourage payment of unpaid invoices or other claims. At the very least, you should send a chasing letter first explaining what they owe and making it clear how they can pay you.

  • What does this document cover?

    This template letter before action covers all the key points you need to include to comply with the law. In particular, it includes reference to the relevant part of the court rules that the other side should look to when considering how they reply (these rules are also known as the Civil Procedure Rules).

    It also helps you make the most of your claim by including options to help you claim the maximum amount of interest that you are legally entitled to.

    The questionnaire of this letter before action includes guidance notes to:

    • help you fill in the details of what happened and what you are asking for in a simple and straightforward way. Being clear about what you want as early as possible improves your chances of sorting matters out without ever having to resort to expensive legal action.

    • make it easy for you to comply with the law, for example when setting a response time after which you reserve the right to start your claim.

  • Why do I need this document?

    It is crucial to get your letter before action (letter of claim) right. The court rules say that there are particular things you have to include in a letter before action and failure to do so can mean you miss out later on, or even get penalised by the court for failing to follow the rules properly.

    Properly completed, this letter will include a summary of what has happened, what you want from the other side (including, if applicable, how any sum of money you are asking for is calculated) and how long you will give them to reply before you start your claim.

    Using this template also gives you the best chance of coming to an agreement with the other side whilst showing them you are serious about taking the matter further if they do not make some effort to pay you or provide you with a remedy. It is usually well worth agreeing things if you can, rather than going to court - even small claims can be slow and expensive, regardless of whether you win or lose.

  • Where can I find out more?

    If you haven't already, you should chase for payment of your invoices before you create a letter before action and send it off. You can use our suite of debt collection letters for this:
