Re: Removal of Incorrect Judgement
first rule: never ignore a summons.
actually, even before that, apparently you didn't even file a response to the complaint. If you had done that, you would have likely been dropped from the suit. Seeing that you were properly served, failed to file a response, and failed to show up for court, there was no mistake, other than yours, that allowed this judgment to be filed against you.
for future reference: if this was a joint lease, every one of you owed the $4200. She could have sued any or all of you end would have gotten a judgement for $4200 against each defendant. She would have been limited to collecting $4200 total though. You can negotiate a separate release as you did but that doesn't prevent one of your co-tenants from suing you if they believe they were injured by you.
In the September 2010, I rented an apartment with 4 other friends. Eventually, we all became severely behind on rent (I ended up owing about $1000, but the other roommates owed more) and we were given notice to quit and vacate the apartment in March 2011.
pay her what? The money you say you don't owe?
I agreed to pay her if it was removed.
What you want can be done, sometimes, but it isn't easy and unless she wants to pay a lawyer to do it, it is unlikely she would be successful. Are you willing to pay for her lawyer also?
You could but it would be denied.
Should I file a motion to vacate?
that's what you should have done in March of 2011. That was what all that hubbub was about back then.
Should I take her back to court again and show them the signed and dated contract she made with?
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
