Yulan Family Law Lawyer, New York

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 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.

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 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.

Someone appointed by a court to care for the property of a minor child that is not supervised by an adult under some other legal method, such as a trust. A guardian of the estate may also be called a 'property guardian' or 'financial guardian.' See also guardian.

The act of freeing someone from restraint or bondage. For example, on January 1, 1863, slaves in the confederate states were declared free by an executive order of President Lincoln, known as the 'Emancipation Proclamation.' After the Civil War, this emancipation was extended to the entire country and made law by the ratification of the thirteenth amendment to the Constitution. Nowadays, emancipation refers to the point at which a child is free from parental control. It occurs when the child's parents no longer perform their parental duties and surrender their rights to the care, custody and earnings of their minor child. Emancipation may be the result of a voluntary agreement between the parents and child, or it may be implied from their acts and ongoing conduct. For example, a child who leaves her parents' home and becomes entirely self-supporting without their objection is considered emancipated, while a child who goes to stay with a friend or relative and gets a part-time job is not. Emancipation may also occur when a minor child marries or enters the military.

A person who initiates a lawsuit. A synonym for plaintiff, used almost universally in some states and in others for certain types of lawsuits, most commonly divorce and other family law cases.

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.
