My ex-husband & I filed for divorce 12/2004, am I able to file for bankruptcy on my own now?

You need to talk to a bankruptcy attorney.  When you see her or him, you should bring along whatever paperwork you have from the 2004 bankruptcy.

I would also suggest that you talk to your divorce lawyer, or find a new one.  In almost every state, a divorce judgment can be changed later on, if there are changed circumstances, and this is especially true when there are children involved.  You may be able to get more child support, and maybe alimony as well although this tends to be more difficult.  If your ex-husband is not doing what the existing judgment says, you can also ask to have the judgment enforced.

You can find lawyers in different practice areas in a number of places, and one of those is our website, http://attorneypages.com
