LAUNDRY owner Keith Rule used Google and an old property law to help 46 British buyers retrieve the funds £1.3 million.
The 46-year-old fought the Spanish bank in order to have his £45,983 deposit returned; on an off-plan villa which was never built because of the economic crisis.
After searching Google he discovered a 45-year-old property law which meant the banks and property promoters were jointly responsible for returning guaranteed deposits on failed developments.
His detection helped 46 others get their money back, and retrieve nearly £1.3 million.
Costa lawyers were so impressed with Mr Rule that they have asked him to work on a part-time basis.
He now combines the day-to-day running of his firm on an industrial estate in his home town with his new job preparing case files for other Brits engulfed in the drama that swept him up when Spanish savings bank CAM washed its hands of buyers after an initial promise of a bank guarantee seven years ago.
The 47 buyers involved in the landmark trial at a court in Albacete province near Murcia, south east Spain, have just received all the money back they put down.
