You have some judges who are still very much pro-mother and you have others who are much more pro-father than the average judge and then you have some in between. Really, which judge your case lands with would have a big role in the outcome of your custody matter if it turns out to be disputed.
Keep in mind 90% of the cases, the parties work out the agreement themselves before a judge ever has to decide it. The judges are pretty good about letting you know throughout the process that you’re better off figuring your own life out—as opposed to letting them do it. Sometimes, they’ll even make decisions that anger both parties to just sort of teach that lesson.
