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.

A child born to your spouse before your marriage whom you have not legally adopted. If you adopt the child, he or she is legally treated just like a biological offspring. Under the Uniform Probate Code, followed in some states, a stepchild belongs in the same class as a biological child and will inherit property left 'to my children.' In other states, a stepchild is not treated like a biological child unless he or she can prove that the parental relationship was established when he or she was a minor and that adoption would have occurred but for some legal obstacle.

An adoption in which there is some degree of contact between the birthparents and the adoptive parents and sometimes with the child as well. As opposed to most adoptions in which birth and adoption records are sealed by court order, open adoptions allow the parties to decide how much contact the adoptive family and the birthparents will have.

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.

Latin for 'friend of the court.' This term describes a person or organization that is not a party to a lawsuit as plaintiff or defendant but that has a strong interest in the case and wants to get its two cents in. For example, the ACLU often submits materials to support a person who claims a violation of civil rights even though that person is represented by a lawyer.

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 court procedure that dissolves a marriage and treats it as if it never happened. Annulments are rare since the advent of no-fault divorce but may be obtained in most states for one of the following reasons: misrepresentation, concealment (for example, of an addiction or criminal record), misunderstanding and refusal to consummate the marriage.

A doctrine that grants the spouse least at fault a divorce when both spouses have shown grounds for divorce. It is a response to an old common-law rule that prevented a divorce when both spouses were at fault.
