The establishment of a clear divorce agreement and custody arrangement marks an important step in adjusting to divorce. Some psychologists suggest the antagonistic nature of the legal system increases conflict between divorcing couples. Nonetheless, it is critical to come up with a binding solution to financial and custody disputes. Once a legal solution is in place, the rancor generally settles down, although some people report ongoing hostility around co-parenting arrangements. Some divorced couples establish friendships after their divorce, but this seems to be relatively rare. The most common outcome is a relatively amicable but not overly involved relationship. Not surprisingly, couples without children generally have considerably less contact after divorce than those with children.
