IIRC OJ never filed BK. Since the civil judgement agianst him was due to his own actions (i.e. not just negligence) it can’t be wiped out in BK.
For example, you hit someone with your car and seriously inujure them. If you are sober and it’s a pure accident you can usually have any judgement thrown out in a bk. If you were drunk or there was any kind of criminal element it’s different.
The primary residence exemption in unlimited in FLA, in CA it only goes up to I think $125k if you have eldery or diasbled people living with you.
A self settled trust gives no additional protection. However, it is very difficult to force the sale of a primary residence in CA. I have been told this by several lawyers.
