Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
When did you first become aware of thsi
Were you on good terms with your parents?
Was the house held in joint names?
Why did the change in the relationship happen?
The difficulty here is that it is likely that your parents owned the property as Beneficial Joint Tenants and the property would have passed to your father in any event.
He would then have been able to leave the property to your brothers in any event - or transfer it to them.
Whilst it is odd that they went about it this way even if he had simply left the property to them in his Will your chances of challenging it would have been slim given the lack of contact over the last six years.
As things stand there is in fact no claim that you can now make, I am sorry.
Please ask if you need further details
You are most welcome I am sorry the news was not better
