If you have a successful bankruptcy, most types of creditors cannot continue any efforts to collect from you. The exception would be for alimony, child support, some income taxes and student loans. This sounds like a poor business model - maybe you would be better off considering another way to make money than entering into a lease that might send you into bankruptcy. Hope this perspective helps!
If you are going into business requiring your personal guaranty on a lease and the business fails, your personal BK will trump your liability on the remaining lease term. No creditor can seize your assets post-bankruptcy unless their debt/lien survives the BK. This results usually from some kind of fraud in the transaction.
If you file a Chapter 7 then your post petition assets and income are protected from your pre-petition creditors. If you file a Chapter 13 or individual 11 then your post-petition income must be dedicated to a plan of reorganization.
