I linked to a post previously about a program like this, but this article has additional details on how the program works. Called Kids' Corner, this provides a safe environment for children to be handed off from one parent to another in situations where violence or turbulence exists. According to the article, "The program prevents having the children come into contact with police who have to show up and quell the violence with their parents."
Still, some people never learn to get along. "Some cases show up 17 years after the couple splits, as the ex-husband and wife battle over issues, such as who pays the college tuition and who gets to see the grades of the students...'Imagine yourself ready to go off to college and getting a fresh start, but having to come back to court to testify how much scholarship money you will receive and how much you have to pay for tuition.'"
