if you run a retail outlet then the likelihood is that from the moment you declare bankruptcy your keys, assets and any stock etc would be siezed either same day or latest next day.
Could I suggest you have a chat with at least one of the professionals on here. I owned a retail shop and Paul from Reviva helped me through the whole system. The main difference is that you take control of your BR rather than everything becoming a giant snowball.
Personally i think it is more important for someone with a business to take expert advice and have them there to make sure you come out of it the best way possible, i have heard of people losing things that they otherwise would not have done had they taken advice. I can only echo s4pps in her suggestion of Paul from Reviva he does a lot of cases involing businesses and is quite hands on ,(he's not a bad chap either)
