If you don’t want to get ripped off when buying inland then you should start by avoiding the foreigners selling property and try to deal with Spanish estate agencies – through a translator if necessary. If you are going to deal with a foreign estate agent then as a minimum confirm that they speak fluent Spanish and have lived in the area for a decade. Many foreigners – especially Brits – who have just moved to rural Spain are now in the property business for lack of anything else to do. For many reasons they are a danger to their clients.
The only reason I can’t recommend you an English-speaking lawyer in the Cadiz province is that I don’t know of one. You might wish to contact the professional legal associations (colegios) in the region and ask if they can put you in touch with local English-speaking lawyers who specialise in real estate law. It’s worth a try but I’m not sure how successful it would be – most collegios don’t give out this sort of information.
