Hello thereThanks for your enquiry.If you do not leave a Will, your Estate passes in accordance with the Rules of Intestacy.
Whether your Wife would inherit everything depends on the size of your Estate and also whether you have children.
Could you please therefore let me know roughly how much your Estate is, whether you have children, and whether any property or accounts are in joint names.
Alternatively, I set out below a link, showing exactly how the Intestacy Rules work.
I look forward to hearing from you if I can assist further.
