Hello and thank you for the opportunity to assist you. My name is ***** ***** I will do my very best to answer your legal questions.
Unfortunately, if the landlord gets a judgment against you, it won't be reduced at all. A judge would award the landlord the full amount that he's owed. Moreover, interest would continue to accrue on the judgment, it would be a lien on your real estate, and the landlord could go after other assets (e.g., garnish bank accounts).
You can still file for bankruptcy, however. It's not quite as easy, but a Chapter 11 is suitable for people whose income and assets are too high for a Chapter 7 or 13. Accordingly, my suggestion is that you retain a local bankruptcy attorney who can not only review your situation in detail and counsel you as to bankruptcy, but who can also contact the landlord and try to settle this without the need for a lawsuit or a bankruptcy.
As an aside, in a bankruptcy you can protect your 401k in its entirety.
Does that answer your question? Please let me know if you need clarification, as I am happy to continue helping you until you are satisfied.
