Equal rights for both parents
I believe if both parents are fit people, they should both have equal custody. "Mother/Father" shouldn't come into it. If a parent pays maintenance, they should see their children without issue. Although I may be hard on my gender, women should not be able to use kids to win an argument. I've seen it happen. If both parents want to be in their child's lives and live nearby, they should share custody and when the child is old enough to make a decision for themselves, they should be allowed to do so.
