Should an estate attorney be working to resolve a property judgment?

I have to sell a relative's home to settle an estate. We know there is a judgment against it for credit card debt. I had a buyer lined up and believed estate's attorney was working to obtain a clear title. Months have gone by and the buyer is called me and asked why we haven't set a closing date. When I contacted the attorney and inquired if he was working on settling the lien, he said that as soon as I pay the debt, I can sell the property. The judgment is more than the estate value. I believe the attorney should be working to get the judgment excused. What should I do?
