An article by Peter M. Walzer, published on the American Academy of Matrimonial Lawyers website, addresses the issue of how fault affects the determination of custody. In it he lists a checklist of some important facts to look for in a custody case.

“The following list describes some common and some not-so-common faults that can be the basis for a change in custody. This list is not intended to cover every imaginable deviation or reason for denying custody. That would fill volumes. It is intended to give the attorney a checklist that could be used in a client interview to bring out possible undisclosed information.

The checklist that follows should be adapted for your community and judge.

FAULT-FINDING CHECKLIST

1. Abandonment of the spouse and the marital home

2. Abandonment of the child to another person

3. Adultery
