Hello and thanks for using Just Answer.
My name is ***** ***** am happy to assist you with your enquiry.
Firstly, if you can, you should try and get your Mother to update her Will or prepare a Codicil.
If this is not possible, and anything were to happen to you before your Mother, her Estate would be distributed in accordance with the strict rules of Intestacy. These rules state that if the deceased dies, without leaving any surviving children, then the Estate will be divided between those children's children. Hence, your children would inherit her Estate and no-one else (this is on the assumption that you did not have a sibling who has died and has surviving children).
I hope this helps and sets out the legal position.
If i have assisted, I would be grateful if you could rate my answer.
