A debt from a home owners association 's dues I never knew I owed, had a partner equally responsible owing home owner association was notified but never paid the debt nor notified me. 
I had move a couple of years before the debt became delinquent. The home owners association turned the late dues over to a collection agency. The agency apparently sent all correspondence to my partner but never to me. They finally to us to civil claims court but never notified me. Got a judgment from the civil claims court but I was never notified of the judgment. Finally, the collections agency alone with their attorney file and received a judgment lien against my home. I never knew the lien was recorded on my property until a year later when the collections company sent a letter letting me know they where prepared to act on the judgment. This was the first I even knew of the original debt. I called and told them I wanted to go back to court which was now over XXXX miles away from my new address to fight this in court. They agreed I was never notified properly of the debt or the judgment, but I 'd lose as the debt was still owed and add more fees to my original balance due plus interest. Once I knew of the debt I paid the collections agency and got a release of the lien, however it still remains on the county records as a judgment and on my credit report.
