In April 2022 the law in relation to divorce (and civil partnership dissolution) in England & Wales underwent a major upheaval, and it is now the case that you do not need to give reasons, or lay blame, in order to get a divorce.
It allows couples to divorce more amicably if that is their wish.
The agreement of your spouse is no longer necessary to obtain a divorce.
No fault divorce takes a minimum of 26 weeks (6 months) from the date of your application.
The court fee for a divorce application is currently £593. Your lawyer will be able to advise you as to the costs involved in resolving any associated financial or child arrangements.
