Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Could you tell me why you think there money involved?
Did they own the property in joint names?
Do you know who paid for the funeral
If the property was not in joint names then Letters of Administration of the Estate would have had to be obtained
You can find out here
If there are no Letters of Administration then they owned the property jointly and the property passed to him automatically when your mother died and it is likely that the life Policy was also assigned to pay off the mortgage automatically as well.
I am afraid that the Ashes belong to either the Administrator of the Estate - or the person who paid the funeral bill
I am afraid that if you want to try and fulfil your grandmothers wishes you will need to appeal to him to return them
Please ask if you need further details
If there is no record then they owned the property jointly as Beneficial Joint tenants and the house passed to him automatically.
At that time a life policy had to be mortgaged in the same way as the house itself and would automatically have cleared off the mortgage.
This would have happened whether or not you stayed with him - it was not because you stayed that he got the money at all.
The issues will be who paid the funeral bill - and if he did then as I said I am afraid that all you can do is ask.
