My baby's father had his son with him for 7 months now. And his other baby's mother is trying to get full custody of him. But the thing is, he's living with me. We're not married at all! Does he need to have his own house to get full custody of his child or will the courts still give him full custody, anyway? Oh, and, he owes child support too. Will that affect his chances of getting full custody of his kid or no?
