Up until July 1, 2003, Georgia set the post judgment interest rate at 12%. That is to say that if I obtained a judgment against you for $10,000, I could add 12% annual interest to the judgment until you paid up.
After July 1, 2003, Georgia required that the post judgment rate be the daily prime rate plus 3%. A lot of states now have a similar rule.
If you are interested, here is the daily prime rate from August 4, 1955, to the present day. Very interesting.
