Question: What kind of judge would agree to this kind of custody arrangement?
Question: When Paul knocks on Holly's door and she isn't wearing anything, she says to him "would you turn around? Oh, never mind, it's such a silly line anyway - I'll turn around instead." What joke is she referring to?
Answer: Holly is referring to the fact that people often ask others in the room "Will you turn around?" when they are dressing or in the nude, so the person cannot see them naked. She is simply stating she thinks it is odd that the second person is always asked to turn around, when the person herself could turn around.
Answer: None. It's total fiction made up solely for the purpose of the movie. Even for a movie, it's far beyond the "suspension of disbelief" that siblings would ever be divided up between the two parents, and neither would have no contact with them, much less be prevented from knowing they had a brother or sister.

It was during the 1960s, the courts had no way of forcing parents to share children. They could have very easily just stayed away from each other out of the view of the judicial system.
This is what I always assumed as well. That this wasn't decided by court, the parents decided this on their own and did not bring it up to the court.
There has actually been a history of separating identical twins as babies, as there has been a fascination in studying what ways they'd be alike, and how they'd be different. During this time period, there were even agencies that would pay women who gave birth to identical twins to give them up for adoption, and have them be adopted in separate families. In today's world, this would not happen, but I wouldn't put it past a judge back in the 1960s.
