Judgement against in Michigan

While trying to get approved for a mortgage, I just found out that I have a judgement against me from 9/1/2002, from an apartment management company. I had a company transfer out of state to NC, and the manager agreed to break my lease without penalty (except forfeiture of my security deposit). I did not get this in writing. Anyhow, they apparently took it to court, and of course, since I was out of state, they won the case for $2600. I have since moved back and currently reside in the state of Michigan.

Since then the management company is no longer in business, and the apartment complex is now managed by a different company.

What can I do to get this black mark off my credit report? Do I need to pay this debt? To whom? Do I take this back to the court? Do I need an attorney? What are the statue of limitations? Who/Where do I go to fix this??

Thanks in advance,
