Sun Lawyers has been added to a list that is maintained on the UK Government website of lawyers located in the area covering: Alicante, Albacete, Valencia and Murcia. The list is for helpful information only, to assist British nationals who may need support overseas. One example may be for sourcing a lawyer to help with a Spanish property purchase. None of the service providers are endorsed or recommended by the Foreign, Commonwealth and Development office (FCDO).
The fill list is here. For now, Sun Lawyers is at the end of the list, as the most recently-added, as opposed to taking its place alphabetically.
