From Wikipedia:
Simpson was ordered to pay $33,500,000 in damages. However, California law protects pensions from being used to satisfy judgments, so Simpson was able to continue much of his lifestyle based on his NFL pension. A 2000 Rolling Stone article reported that Simpson also still makes a significant income by signing autographs. He subsequently moved from California to Miami, Florida. In Florida, a person's residence cannot be seized to collect a debt under most circumstances.
