if a couple is unwedd in the state of pennsylvania who would
have legal custody of the child if they were to separate?
It depends on whether the father is the recognized father. If not, then the mother. If he is on the b/c and has assumed paternity, then either one can 'take' the child and have custody until a court hearing took place.
However, if either parent 'ran' with the child then it will go against them in the court hearing.
