A neighbour received a small commercial rental property in 2011 when husband died. He inherited the property in the 1970s. Property still in husbands name I am told no tax paid at any time. Widow has now agreed to sell the property for 130,000. These people have always lived on social welfare and cash economy and are not used to tax. Is here a CGT liability here ? How do we establish the historical values. They have never lived in this premises.
