Perhaps the most tragic thing about most divorces is that two people who have shared so much end up fighting each other as passionately as they may once have been attracted to each other. But for some, divorces can be amicable. Some couples effectively see and use divorce as a healthy, necessary step towards happier lives. This often happens in the form of an uncontested divorce, and couples find they more quickly, less expensively, and less traumatically move forward with their lives.
In amicable divorces otherwise contentious issues can serve as reasons for keeping things civil. Children often get bounced around like ping pong balls in divorce proceedings. An amicable divorce actually lets both parents consider the children's needs first before their own wants. When they can afford to they can actually leave the children in the home they are used to, and take turns living there themselves, so the children need not live with the extreme change of a new home along with the separation of their parents.
Money also motivates hostility during a lot of divorces. When joint resources are all that either partner has for property, especially if invested in a business, a friendlier divorce process wherein both partners focus on each other's future well-being simply makes sense. Both individuals could be much better off by not contesting terms they can agree on themselves and still protect their mutual interests.
These are only two examples of benefits of amicable divorces. Of course, this takes a lot of trust, trust between the divorcing partners and trust in the attorneys involved. Even if a divorce is uncontested and partners believe that they can completely trust each other, having separate attorneys is still a wise choice. Attorneys don't want to pit two people against each other; they want to create the divorce process and outcome that their clients hope for.
