"You do not sign off on a disaster situation, what you sign there is for normal daily situations like if there is a little storm or high water or something like that,” he said. “This was such a large failure by the captain and by Costa that you can sign whatever you want but you will still get your money.”
Depending upon their individual situations, he said he is seeking between €10,000 ($13,000) and €50,000 ($65,700) for his clients and would wait for three months to see if Costa would settle before taking the matter to court.
Though the cruise company is Italian, Costa’s parent company is Miami-based Carnival Corp. and Reinhardt said he was trying to determine which could be held responsible for the incident. If it’s Carnival, he said he would pursue his case in the U.S., where damages awarded tend to be higher than in Germany."

The first story I’ve seen discussing the compensation for the Costa Concordia passengers. 

Having family in Germany who have had been tied up in the German legal system for some 10+ years now, if it is determined that Carnival is responsible, the German passengers should consider it their lucky day.
