What dirt can you dig up on your spouse or vice-versa?

Let me preface my answer by saying that I do not encourage people to dig up dirt on their spouses, nor do most of my clients engage in that kind of mudslinging. However, the income, personal choices, relationships, medical history, psychological history, spending habits, addictions, substance abuse, and many other aspects of a person's life can be relevant to determine how fit he or she is as a parent. You need to remember that those factors are primarily relevant to the issue of child custody and parenting time, if they are even pertinent at all. The sensational celebrity custody fights really don't play themselves out all that often in real life.
