Why are you thinking of amending the probate value of the property? To possibly reduce capital gains tax. The late Mr Ryder died on 14 Feb 2010, and his capital gains tax allowance may be allowable?
How long ago was the property valued for probate purposes? Soon after Late Mrs Ryder's death on 15 April 2013.Probate was granted on 24 June 2013 and the house sale completed on 29 Nov 2013.
Was the property sold within the deceased estate or was it transferred to you before it was sold? Was it owned solely by you or jointly with your wife? Sadly, within the estate, we were not advised otherwise.
