Divorce ith husband in jail and paternity in question...

[brie2017]

OK...So, my friend is in prison and has filed divorce papers several times to no avail. He wants a divorce with a paternity test on his son to make sure he is the father, because his wife has had two other children during their marriage by two different men. They have never lived together as husband and wife. They have never even consummated their marriage because he has been in prison for 98% of their marriage. Can anyone help out with some advice? He obviously cannot afford a lawyer since he is currently incarcerated.
