It can be difficult to know whether it is the right time to make an application to court. Writing a warning letter can be a good way of avoiding court proceedings. Sometimes it is not safe to send a warning letter, in which case you may need to go directly to court without informing the other party. This legal guide will give you information about how and when to write a warning letter.

Rights of Women publishes a number of other legal guides that may be useful including Family Court proceedings: where can I get advice and support? , Domestic violence injunctions and A guide to preparing for court hearings and safety in the Family Court.  

What is a warning letter?

A warning letter is a letter or email which you write to inform someone that they must change their behaviour or you will make an application to court. For example, you may wish to ask someone to stop harassing you, or obtain permission to take your children abroad on holiday. By sending someone a warning letter you are giving them one last chance to resolve the issue by agreement without the need for court proceedings.

It may be easiest to send the warning letter by email as you can print a copy. You can also post the letter to the recipient’s home address or to anywhere else you are sure they will receive it. If you are posting the letter, remember to make a copy.

It may be that the warning letter resolves the issue. If the letter does not resolve the issue then you can make an application to court. When you make your application, remember to attach your warning letter and any response you received or any evidence you have that the warning letter was ignored by the other party. This will show the court that you have tried to resolve the issue amicably and that the other party was aware of your wishes and feelings but chose to ignore them.

When might you send a warning letter?

You may wish to write to someone to ask them to stop doing something. For example:

  • to stop harassing you or contacting you at all by telephone, text or social media
  • to stop being aggressive during handovers for child contact
  • to stop cancelling contact arrangements at the last minute

You may wish to write to someone to ask them to agree to something. For example:

  • to allow you to return to the home to get your belongings
  • to move out of the family home
  • to give you permission to take the children abroad on holiday
  • to pay you some money that you are entitled to

When should you not send a warning letter?

Sometimes it will not be safe or appropriate to send a warning letter and you may need to go straight to court without informing the respondent. This is called a without notice application. Examples of situations where it may not be safe to send a warning letter include:

There may be other reasons why it is not safe to send a warning letter.  If possible, seek legal advice before sending a warning letter.

Top tips for writing warning letters

  • Only send a warning letter if safe to do so. If you are unsure whether it is safe, do not send the letter and get advice about obtaining an injunction.
  • Only send a warning letter if you have an address or email address where you can be reasonably sure the recipient will receive it
  • Make sure you keep copies of your warning letter
  • Include in your letter a date by which you expect a reply or action to be taken, if appropriate
  • Try not to engage in any other dialogue or correspondence which may confuse your position
  • If your letter is ignored and the problem continues, you should make your application to court
  • When you make your application you should also provide the court with a copy of your warning letter and any response you received and evidence that the letter was ignored
  • If you send the letter by post, it may be helpful to send it by special delivery or other tracked delivery service. Keep hold of the tracking number and confirmation of when the letter was delivered so you can show this to the court if you need to.
  • If you send the letter by email, it may be helpful to request a ‘delivery receipt’ and ‘read receipt’. This is so that you can check the email was delivered and that the other party has read the email.  Keep hold of the receipts so that you can show them to the court if you need to.
  • You can use a solicitor to write and send the warning letter for you. You may be able to get legal aid to pay for the fee.  If not talk to the solicitors in your area about how much they will charge to send a warning letter.
  • If you cannot get legal aid or pay for a solicitor then you can send the letter yourself.
