From a legal standpoint can people go after my ets to collect on my husband's debts?

My husband and I are not together anymore, but are still legally married. He has a lot of past due credit card debt and owes back child support to his ex wife because he hasn't been working. We have no joint accounts or ets of any kind, but I want to know if legally I should be worried about people coming after me and my money to collect on his debts? We have two kids which live with me and he is not supporting in anyway, I want to make sure my money in my bank accounts will be safe.
