My sister an I are equal beneficiaries of my late mothers property. My sister is currently living in the property and has done so for a number of years. My sister intends to buy me out of my half of the property and the property has increased in value since the date of death / acquisition. Does it make sense to Assent the property first (as per the will) before a Transfer Of Equity as I understand that the estate only has one capital gains allowance?
