Thanks for your reply and apologies for the delay.
Well, I am afraid there will be Stamp Duty payable by you on your brother's half share.
There will be no Stamp Duty payable on the half share you inherited.
Stamp Duty is payable at a rate of 2% for any consideration paid over £125,000.
Therefore Stamp Duty will be £5,000 (£375,000 less £125,000 equals £250,000x 2%= £5,000).
The only way around this would be if your brother were prepared to give us his inheritance of the half share of the property. If so, a formal Deed of Variation can be prepared by a Solicitor which varies the terms of the Will post death, to in effect show that you are entitled to inherit the whole of the property.
There will also be Solicitors fees to pay (not a vast lot- probably £300 plus VAT to do the paperwork and a Land Registry fee of £90).
You may also have to pay Capital Gains tax as and when the property is sold.

There are no other issues you need to be made aware of from a legal point of view.
I hope this assists and answers your question.
If so, I would be grateful if you could rate my answer.
