single expecting mom needs help in Child Custody & Support Posted January 1, 1970 · Report reply "When do I file papers for the DNA test? Do we have to wait until the baby is born to file the papers?" Yes, you have to wait until after the child is born. Until the child is born, a determination of paternity is legally meaningless. "Can we go through a third party for the DNA test and then have the results sent to the courthouse?" I don't know the specific procedure in Minnesota. Presumably, you (i.e., the child) and the alleged father will be ordered to go to a testing facility to provide samples, and the testing facility will report the results to the parties and the court. Consult local counsel about this.
