Consensual sexual relations by a married person with someone other than his or her spouse. In many states, adultery is technically a crime, though people are rarely prosecuted for it. In states that have retained fault grounds for divorce, adultery is always sufficient grounds for a divorce. In addition, some states alter the distribution of property between divorcing spouses in cases of adultery, giving less to the 'cheating' spouse.

Overdue alimony or child support payments. In recent years, state laws have made it difficult to impossible to get rid of arrearages; they can't be discharged in bankruptcy, and courts usually will not retroactively cancel them. A spouse or parent who falls on tough times and is unable to make payments should request a temporary modification of the payments before the arrearages build up.

A mistake by both spouses in a marriage that can serve as grounds for an annulment. For example, if one spouse went into the marriage wanting children while the other did not, they have a misunderstanding that will be judged serious enough for a court to terminate the marriage.

One person's approval of another's activities, constituting a defense to a fault divorce. For example, if a wife did not object to her husband's adultery and later tries to use it as grounds for a divorce, he could argue that she had condoned his behavior and could perhaps prevent her from divorcing him on these grounds.

A court procedure by which an adult becomes the legal parent of someone who is not his or her biological child. Adoption creates a parent-child relationship recognized for all legal purposes -- including child support obligations, inheritance rights and custody.

A tradition that required one spouse to prove that the other spouse was legally at fault, to obtain a divorce. The 'innocent' spouse was then granted the divorce from the 'guilty' spouse. Today, 35 states still allow a spouse to allege fault in obtaining a divorce. The traditional fault grounds for divorce are adultery, cruelty, desertion, confinement in prison, physical incapacity and incurable insanity. These grounds are also generally referred to as marital misconduct.

A situation set up so that another person commits a wrongdoing. For example, a husband who invites his wife's lover along on vacation may have connived her adultery, and if he tried to divorce her for her behavior, she could assert his connivance as a defense.
