My name is not on the first mortgage BUT?

it is listed on the 2nd and 3rd mortgages. Is there anyway for my name to be taken off of the 2nd and 3rd mortgages? And if so, can I then file bankruptcy without my husband? Most of our debt that is unsecured is in my name. My husband has the first mortgage and 2 small cc balances. Any suggestions? We have been living paycheck to paycheck and robbing peter to pay paul. Thanks!
