Är nog inte så många som har bra koll på hur "kronofogden/inkasso" jobbar i Spanien. Tror Google eller samtal till dem är det du får görakan nån snälla svara här ang det jag skrev?
Unfortunately not. The practice of just sending the letter to the address to the addressee and it then being assumed as received and acknowledged is not applicable everywhere, thus if they send a letter to a foreign address, and it gets send back, they have no recourse.
So in Sweden that principle works, but not in other countries, there the letter MUST be sent as a recommended signed for letter to be acknowledged. Besides the law is in many places different than in Sweden; he who demands needs to prove that you have received and read the contents of the letter. Without that signature you have no proof. That is why in many countries the incasso procedures run through recommended letters at a certain point, because otherwise they lose in court.
What counts under Swedish law, does not count everywhere ;-), and thank God for that.
