These days people call me with their judgments, and I immediately go on one of my prof. databases, and investigate the judgment debtor. In 30 seconds I know where he or she lives, homes, cars, professional licenses, boats, and tons more. From there I can identify whether the person is a "better debtor." And whether I want the judgment in the first place.
-I've advertised for judgments on Google Adwords
-I've "mined" for judgments on databases (yes, you can too)
-I've searched for judgments at the county courthouses
Whichever way you find them, the key is to investigate before accepting any judgment. Always do that. I'll repeat - Always. You don't want anything on your desk that isn't doable. And it doesn't take many good judgments to make good money.
If you have questions, please let me know.
