Is it legal to use husbands credit card he filed for divorce stay at home Mom for 9 years just went to work everything is in his name I have no money but need a lawyer?

The legality of using a credit card is based on state law and the credit card agreement between the issuing bank and the holder. Its not a yes or no answer. You would have to contact the bank on the back of the credit card and learn what the agreement was in your case.
