Can I declare bankruptcy again if I did so in 1997?

You do not have a need at this point. Go to a family lawyer; sue for divorce AND equitable distribution. Any asset purchased during marriage is a marital asset no matter what your husband thinks. Any liability incurred during a marriage is a marital debt no matter what the husband thinks. You may well qualify for having your husband pay for your lawyer. The first thing you need to do is file a pendente lite motion which requires the husband to keep all insurance in place, and not to liquidate assets. Good luck.
