The question of what happens with the debt depends in part upon whether its exclusively in your spouse's name or if it's joint debt (if your partner signed your name to loan applications, that raises some additional potential issues) and what the money was used for. If the money was used to support the household, even if you were not aware that it was borrowed you enjoyed the benefit of the money. If, on the other hand, your partner was secretly borrowing money to support a drug or gambling habit, you have a decent case for arguing that the loans were secret, did not help (and perhaps harmed) the family's ability to support itself, and that you should not be responsible for the debt.

If these debts are in your name, you should explore removing your name from them. If your partner defaults on the debt you don't want the credit card companies to be able to pursue you.

The question of child support is separate from the division of marital debts and assets. Most states require judges to follow the formula, absent the court's finding that the case fits a narrowly defined reason for departure.
