We once had an incompetent Solicitor in the UK. He had POA to sell our house as we were overseas. House had a tenant, he mixed up the dates at a cost to us of some £1900. We went through the complaints procedure, took a few months, we received a cheque not only for the loss but all legal fees we had paid. I don’t think that would happen in Spain. The Colegio de Abogados appears to be a sort of Trade association solely interested in protecting their members.
I do agree there are some good honest Lawyers in Spain but if they are concerned about their reputation they should be pushing the colegios for reform to flush out the bad guys.
