The Beginnings

I founded CostaLuz Lawyers in 2006 with the idea of attracting property investment to the Costa de la Luz in southern Spain and help English-speaking foreigners buying property to retire to, live in or spend holidays in Spain.

My founding principle was to help foreigners understand how Spanish law works and get the best possible outcome for their interests. This mission now forms one of the pillars of CostaLuz Lawyers.
