I'll be very candid with you, your odds of success here are not very good. The problem you have is that the debts that were accumulated during the marriage are considered to be marital in nature. As such, the debts are presumed to belong to you both, not just to one or the other.
Having said that, you can certainly try to persuade the judge to distribute the debts in some other way. With the documents you may have, you should be able to put together a compelling case.
You will want to include this information in your pleadings. From the start, you need to state that the earlier debts were primarily your husband's, that the bankruptcy was essentially forced upon you and that the new debts are primarily your husband's as well.
You will need the statements from the older debts. If you don't have them any longer, contact the creditors to obtain copies. If the creditor no longer has them, you should contact the attorney that handled the bankruptcy, he likely still has his file with whatever documents you provided. If all else fails, you can issue a subpoena to the creditor, they will most likely be able to produce the records if court ordered to do so.
Then you will have a paper trail for the court to review. The documents will demonstrate what you have alleged; your husband created the debts, he then transferred them to you, you subsequently declared bankruptcy and he has now created significant new debt.
With all this, you just might be able to convince the judge that he should ignore the marital component of the debt and distribute a greater portion of that debt to your husband.
