The biological father of a child born to an unmarried couple who has been established as the father either by his admission or by an agreement between him and the child's mother. An acknowledged father must pay child support.

A term used instead of defendant or appellee in some states -- especially for divorce and other family law cases -- to identify the party who is sued and must respond to the petitioner's complaint.

A document that provides proof of a marriage, typically issued to the newlyweds a few weeks after they file for the certificate in a county office. Most states require both spouses, the person who officiated the marriage and one or two witnesses to sign the marriage certificate; often this is done just after the ceremony.

A special kind of property ownership that's only for married couples. Both spouses have the right to enjoy the entire property, and when one spouse dies, the surviving spouse gets title to the property (called a right of survivorship). It is similar to joint tenancy, but it is available in only about half the states.

A document that authorizes a couple to get married, usually available from the county clerk's office in the state where the marriage will take place. Couples pay a small fee for a marriage license, and must often wait a few days before it is issued. In addition, a few states require a short waiting period--usually not more than a day--between the time the license is issued and the time the marriage may take place. And some states still require blood tests for couples before they will issue a marriage license, though most no longer do.

A legal reason for obtaining either a fault divorce or a no-fault divorce. It is rarely used, however, because of the difficulty of proving both the insanity of the spouse being divorced and that the insanity is incurable.
