Hi dimitri. Welcome
I am not to familiar with BK but I do know that in some cases it may be necessary.
I have some information that I can guide you too. We also do have several members here that have experience with BK and hopefully will jump in to offer advice/suggestions.
In the meantime, here are some good resources.
Periodicals Bankruptcy Information, FAQs, Chapter 7 &13 Information.
