Sorry Fatmanfilms, - you not so easy of the hooks.
Having a company here (or as private) I can not easily re-locate myself to England, declare myself as bankrupt, stay there for 12 month and I am dept free. It doesn't work this way.
If you member of the EU, maybe, but definitely not Switzerland.
Here, I suit you, (Betreibung), you'll be public notified if you have relocated to unknown (England), and then lawfully declared as bankrupt if you not showing up and face the charges. The depee is getting a "Verlustschein", this one is (since 1997) valid for 20 years. The once issued before will expire 2017, doesn't matter how old! If you come back after this 12 month from England, open your company here I'll promise you the minute your personal details are published they will line up to turn your pockets upside down.
If you British and bankrupt there, this is an entirely other story as then you would have to claim this money all the way here. If you declared dept free after 12 months in England, then they can't claim here anymore. However - you have to ride out this time in England (by all means give the deptee's a chance to get something from you). Only then you can have a fresh start here. As it concerns Switzerland, no one is interested in your past. Havening dept's in England or not, is not a legal issue here.
A Swiss court an not overrule a decision from a British court. And visa versa. So a Swiss court declared you bankrupt and the "Verlustschein" is issued, a British Court can not cancel this decision.
