What can I do to get this off or can I get reduced to the principal amount?

I thought my credit was cleared up until I tried to buy a house. When a title search was done, it showed an old judgment from 2006 on an unsecured credit card showed up at the courthouse. This card started out at $1634.87 and it now shows $11,924.25 due. I had paid about $4,000 on it and it was taken off my credit report but they still show I owe this. They show I still owe all the interest, court fees and lawyer fees.
