Don't know if there's a difference between Italian and English law, but when Fiorentina went bust, called themselves Florentia Viola and eventually bought the name back, they were always seen as the continuation of the old club. By contrast, when Wimbledon became MK Dons, AFC tried to win back the honours list, which was fair enough given that only they were called Wimbledon, but there was a dispute and the titles ended up as the property of Merton Council, the local council around the Wimbledon area.
