The law protects the debtor from having his or her entire paycheck garnished by multiple judgements in setting a specific percentage that is permitted to be taken out by law.  You can not leave a person with nothing to live on, even if they owe a million people. And child support will take priority over other judgements rendered.  There are other methods of collection besides garnishment. You can levy against a bank account; you can file a lien against real property and you can request help from the Sheriff or Marshall in levying against personal property and selling it to pay off the judgement.  Get help with these other methods of collection.  Good luck.
