Hello, thank you for the question.
I am a UK qualified solicitor and happy to help.
You would first need to decide on one of the ground for divorce: adultery, unreasonable behaviour, separation by consent after 2 years, separation without consent 5 years, or desertion.
You then need to fill in form D8 (see attached) and send to your local family court in Dorset with a fee of £550.00 payable to HMCTS. The court will then serve the divorce petition upon your ex who has to then respond to it with an acknowledgment of service, either agreeing to the divorce or contesting it.
Have you spoken to your ex about this yet and also have to talked about finances (in case you want a financial settlement).
I hope this helps - if you can please accept the answer and give me a star rating (there should be a row of 1-5 stars at the top of your screen to allow you to do this), I can answer follow up Q&A's at no extra charge and Just Answer will credit me for helping you today.
