If i will an assault/punitive damage lawsuit against a person and he has no means of paying my I take his person property

You must obtain a judgment to win. If you gain a default judgment because the defendant does not answer or appear, then you must prove up your damages. That will take an evidentiary hearing that follows all the rules of evidence. Should you persuade the judge will enough evidence then a judgment may be entered. With that judgment, you may attempt to seek assets to go after. Some use a Citation to Discovery Assets, but for the absent non appearing defendant that presents major problems. You may only go after assets held by the judgment debtor. Not his relatives. Not his children. If the marital assets are truly joint, then perhaps a method to go after them might exist. This is complex stuff. Hire counsel.
