The divorce process is notorious for fostering contention. Feelings of anger, pain and revenge can cause spouses to choose not to act cooperatively to hurt each other. Even without those emotions, disagreements over the division of property and time with children are inevitable.
Mediation is great for couples who still get along reasonably well and want a less stressful separation process. However, those with disputes and conflicts may still find this a viable solution. It may also be possible for individuals in abusive relationships to benefit from mediation because it can help provide strength to the person who suffered abuse.
