I live in GA and received a judgement a few years back. According to the instructions on the judgement, I am entitled to the judgement plus interest but how do I go about getting it? The defendant has property which is not being used (with an abandoned trailer,old car, and other meaningless junk on the property) in his name but the property has little value to me unless I can sell it. Everything else is in his mom's (or some other family member's) name with him listed as the c/o person at another address which he does not own. How do I attach a lien to the property listed in his name and when or can I sell it after he does not pay me? What is GA law regarding the amount of revenue I receive/keep?

You may attach a lien to your land, but you can't force him to sell it like a mortgage, you merely have to wait till it is sold, in 3 years in 30 years.

Winning a judgement and ever getting money is two different things, many many judgements never get a penny paid. You can attach any of his bank accounts if and when you find them, if he is working you can get a garnishment against his wages.
