@Markerrag -- that's not necessarily true. For example, let's say you have a wife that works her fingers to the bone to send her husband to law school. Husband graduates, passes his bar, gets a well paying career and picks out a younger wife to go with it. The original wife would darn sure have something to fight about in court -- perhaps she is entitled to some spousal support as her reward for sending her husband through law school. That is an issue that would probably not be worked out in an uncontested divorce.
Or, here's another scenario. Let's say a retired couple is splitting up and the husband is drawing a large pension. You can almost bet the wife will want part of that pension and you can bet the husband won't want to give it to her. In that case, a court could decide whether at least part of the pension is marital property and how much of it the wife should receive.
There are other times an uncontested divorce isn't practical when no kids are involved, but the point is made.
