Divorce can cause emotions to run high and instill a "me vs. them" attitude. It can cause otherwise sane and stable people to become angry and vindictive. This can be due to seeking custody of your children or accumulating more of the assets once the property is split up. What can easily happen is that one person in the divorce may decide to illegally hide assets they don't want exposed during the divorce.
Splitting or sharing friends that you and your ex-spouse have in common can be a huge challenge for divorcing individuals that are already dealing with the legal and emotional complexities of divorce.
