Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first.
Who actually owned the property, how much was it worth and how much is outstanding on the mortgage?
What is the rest of the estate worth and what has his partner actually done?
Just for clarity - the only reason that you think that she is claiming is because it is mentioned on the IHT400?
Did your father also put cash down on the property?
Do you know how much?
Actually that seems about right - but we do need to know the various figures involved!
I think this is merely a matter of incorrect form filling rather than anything more sinister - but i need to get an idea of the figures first
