My 3 yr old son's father and I ended our relationship recently. His father has physically been out of his life for the last year, and my son knows him only through phone calls, as he is in another state. He has never been able to hold a job for long, barely even supporting himself. So he has no means to support his son, and a shady background that would prohibit him from properly nurturing him. ( I assume I have sole legal and physical custody, since his father hasn't requested custody. There hasn't been any legal action between us at all- no court orders.) Can I draw something up legally, with or without a lawyer, to have custody go to my parents (who are helping me raise him now), in the event of my death?
