Defenses in Fault-based Divorce: Mental Illness

Divorce statutes in most states consider several defenses in case of fault-based divorce, such as recrimination, condonation, reconciliation, collusion, and connivance. States traditionally have allowed mental illness as a common law affirmative defense in fault-based divorce actions, particularly against charges of adultery, cruelty, and desertion. Under a typical scenario, the defendant was required to plead the defense and prove that mental illness prevented the defendant from recognizing that the offending act was wrong. In states that allow fault-based divorce and that have detailed statutory schemes governing divorce actions, the general movement has been to limit or eliminate common law divorce defenses such as mental illness.

Grounds for Annulment: Mental Incapacity

Under the law, a marriage is voidable in cases where either of the spouses is incapable of understanding the contract of marriage. Some states hold that if the party is incapable of understanding because of insanity or serious mental disorder, the marriage is void. Some state statutes provide that mental illness can be a ground for annulment if the defect prevents the afflicted spouse from appreciating the contract and conferring thoughtful consent to the marriage.

Role of Expert Witnesses in Divorce Proceedings

Witnesses can be fact witnesses who testify to facts, or expert witnesses who can testify to facts as well as give their opinions. Expert witnesses are engaged to provide testimony regarding their knowledge in a particular subject. Such knowledge is beyond that of the average person by virtue of the expert's education, profession or experience so that their opinion will assist the judge or jury in making a decision. In divorce proceedings, many times physicians, psychologists, social workers, pension analysts, and appraisers are engaged as experts.

Property Division in Divorce: Partition

For purposes of divorce, "partition" is a legal process that divides property, usually real property, into fractional shares for the spouses. Divorce or legal separation establishes grounds for partition in a divorce for jointly-owned marital assets of the spouses.
