To KevinXatura & macgd016, thank you both for taking the time to reply to my query. I take it that you have no suggestions as to how to reduce the capital gains tax liability. KevinXatura – I am 100% sure that neither my wife nor I have selective hearing. Our lawyer at the time did not discuss with us any proposal to pass over some of the purchase price in cash or to insert a reduced amount in the Escritura. I gave my lawyer power of attorney to act on my behalf and I have a copy bank statement showing 4 entries that he passed at the time of purchase which total approximately the purchase price. If cash was involved then I can only assume that one of the entries relates to cash being withdrawn. However assuming that this is the case then when I add any 3 entries together they do not total the amount shown in the Escritura. I think my lawyer was being very careful to not show clearly how this scam worked.
