Can I sue someone who put a levy on me that shouldn't have been there

Hi. If I could just give you some info, maybe I'm missing something. My husbands ex-landlord took us to court 3 weeks ago. Back in June 09' she had stopped cashing my husbands rent checks that were written from my accout (my maiden name). She had held June, July, August and September rent checks. She would never answer our calls to see what the issue was. In March 2010, she took my husband to court for unpaid rent bc by this time, he had just stopped paying. She got a judgement against him for unpaid rent Oct 09'- march 10'. She had my 4 checks still at this time for June-Sept. Once the judgement went against him, she had tried to cash my checks which by this time were passed the bank policy (they were stale-dated). So now she takes us back to court and tries to sue me under my maiden name and my husband for unpaid rent. Long story short, we had a mediator and came to an agreement that my husband was responsible for the total amount. Just a note to add, my name was never on any lease agreement, only his. So they settled on an amount with me taken completely off of the complaint. They dismissed me with prejudice on July 29, 2010. August 16, they levied my accounts and wiped me clean-- $9000. Left me with pennies compared to what they took. I sat in court for about 8 hours trying to get to the bottom of this. Nobody understood how this could have happened being that I was dismissed with prejudice 3 wks prior. I don't know if the court screwed up, or she was trying to pull a fast one, or maybe she knew someone. I don't know. I sat and saw the judge in the morning and then again in the afternoon. He kept insisting that I had a judgement against me until I showed him the settlement paper which he overlooked in the morning session. He then looked a little concerned and scheduled an emergency hearing bc he said he couldnt lift the levy unless all parties were present. He looked a little mad after he saw that paper. Almost like he was mad at the ex-landlord for being sneaky or maybe in his hearts of hearts he realized that someone in house screwed up but I know that they would never admit that.. So here I am, with a 14 month old baby, no money and husband who's going back to school. He knows he has to pay her and he had already agreed to it, but 3 wks is a short time to come up with 8000. I just dont understand how they levied me If I was dismissed with prejudice--- I'm sorry to go on and on... I just need all the help that I can get... and believe me, it's appreciated...
