inheritance tax and purchase

hi, myself and my brother inherited a second home property and I have the probate valuation of this property. Some years later I bought out my sibling's half. What value do I use when completing the form - the value I bought or inherited the price? Or do I split both values up 50/50 and submit the average? Which box do I tick - inherited or bought? Also, do I include the solicitor fees when I purchased the property from my sibling and solicitor fees when I inherited the property or,again, average them out? Thank you.

Hi,
The acquistion cost will be made up of 50% of the probate value at the time of inheritance and the sum paid to your brother for his 50%, assuming this is more than the probate value.  If less than the probate value, you would use the probate value.
Thank you.
