Here's the thing about Chapter 7 bankruptcy, especially is you are "early retired"

- if you keep a lot of cash (preferable invested in the stock market) while at the same time holding unsecured debt (which can, or at least could, be done with low-interest balance transfers), then once you decide to cross the Rubicon, you can live off of that cash, and as well buy stuff that is considered a regular need (including a cheap house in my situation, the official purchase of which I did not 1 hour before signing the official paperwork with my attorney

), and since you already had that cash lying around, it isn't considered bankruptcy fraud like it would if you were to take cash advances before filing. (I should say that you should always be socking away the maximum amount in your 401K/IRA, which is something that you would keep in a bankruptcy OR divorce, LOL.)
Keeping a lot of debt would also be a good idea if you ever got married to a gal with a lot of debt, like student debt, that way you could pay off your debt together.

Your retirement account would be YOUR property, not community property. When debt is paid off in a marriage, you don't get your part back.
