Martha, thank you for your question and your kind words.
Let me see if I understand this correctly. You had a buyer for your property who paid a reserve amount of 10,000 Euros to your solicitor 6 months ago. Your solicitor held the money on your behalf. However the buyer has pulled out of the purchase, losing the 10,000 Euros reserve payment, which your solicitor is now keeping and refusing to pass on to you. Is that the case? If so on what grounds does your solicitor refuse to pass on the money to you? Have they given you any reason? Do you have a copy of the Contrato de Arras (reserve deposit contract) that you signed with the buyer? Excuse me asking these questions but I need to clarify the problem before I can be of any use.
