MY kids father is locked up in moose lake prison in Minnesota. I say we have four kids together but he denies all four. If he had a choice he would choose 2 of the four kids. I need to establish paternity as quickly as possible.. my questions are 1. Can he be tested in jail? 2. how can I receive child support if he never worked and lives in another state? 3. is there anyway to get testing done for free while he is in jail?
