Judgments can last indefinitely. However, the plaintiff (usually the creditor or debt collector) must renew the judgement every ten years. If the plaintiff fails to renew the judgment before ten years has passed, the judgment is no longer collectible. Also, judgments collect 10% interest per year.
Once the creditor or debt collector gets a judgment against you, they can garnish your wages, levy your bank account or put a lien on your property. However, if you can show that your wages are necessary to support you and your family, you can exempt your wages from collection. Additionally, there are certain types of income that cannot be collected, including Social Security money, VA benefits, retirement benefits, GA, EDD, CalWorks, pension plans, IRA, etc. These types of income exempt from collection.
