Thanks for your reply.
She would not be able to sell the property unless either the property was in her sole name or if it was in the name's of her and your father AND she had a grant of probate/letters of administration showing that she has the right to deal in your father's estate
You can download a copy of the register for your property from the land registry's search engine:-
Enter the postcode for your property and if it is registered it will give you the option to download a copy of the register.
You will be able to tell if it is registered in her sole name by looking at the proprietorship register.
If it is then she could have owner the property with your father as joint tenants, which means that the property would pass automatically to her following your father's death regardless of if there was any will or whether his estate would pass according to the intestacy rules.
The intestacy rules state that she would receive up to £250,000.00 of his assets would go to her, anything over that would pass to you and your siblings - half now, and half once she passes away herself. If his share in the property was less than this amount then she would receive it even if it was in your father's name and he did not have any other assets.
If his estate was greater than £250,000.00 and he did not have a Will then you should have received something. You need to check to see if a grant of probate/letters of administration was taken out:-
If letters of administration were taken out and your father had an estate greater than £250, 000.00 then it could be that she has effectively defrauded you of your inheritance. Chance are it will have been in their joint names earlier and then passed automatically to her.
