I would 100% recommend using Castelo solicitors… I have had the pleasure of working with Maria, she has been amazing. She managed to sort everything out for me and my family. She went above and beyond. When there were complications, she sorted it all out. All of the team at Castelo have been amazing and very efficient. I would definitely use them again. Thank you so much.
