Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first
Who are the executors of the Estate?
Are you raising a mortgage for the purchase?
Just to check - is the property still held in the name of your late father?
My apologies for the delay
Who has told you that Stamp Duty is payable?
Your brother has missed the point entirely
Stamp Duty would not be payable in any event since this is an Inheritance and you are simply "buying him out"
You will pay the money into the Estate and then an AS1 will be completed transferring the property into your name.
In any event even if this was not the case the argument is fallacious - you might not have purchased another property at all!
Please ask if you need further details
