Work address

[optimus]

Hi,
Here is the story. A guy owes me money (decision of the judge). I want to collect that money from him, but before I put a lean on his property, I'd like to start from garnishing his wages, this way, I'm sure I will collect my money, but the problem is I do not know where he works. Any idea how I can find his work address?

Thanks a zillion times for your help.
