Gerry Divorce & Family Law Lawyer, New York

In some states, a type of marriage in which couples can become legally married by living together for a long period of time, representing themselves as a married couple and intending to be married. Contrary to popular belief, the couple must intend to be married and act as though they are for a common law marriage to take effect -- merely living together for a long time won't do it.

Papers filed with a court clerk by the plaintiff to initiate a lawsuit by setting out facts and legal claims (usually called causes of action). In some states and in some types of legal actions, such as divorce, complaints are called petitions and the person filing is called the petitioner. To complete the initial stage of a lawsuit, the plaintiff's complaint must be served on the defendant, who then has the opportunity to respond by filing an answer. In practice, few lawyers prepare complaints from scratch. Instead they use -- and sometimes modify -- pre-drafted complaints widely available in form books.

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.

A trust for children in which the trustee decides how to spend money on each child, taking money out of the trust to meet each child's specific needs. One important advantage of a pot trust over separate trusts is that it allows the trustee to provide for one child's unforeseen need, such as a medical emergency. But a pot trust can also make the trustee's life difficult by requiring choices about disbursing funds to the various children. A pot trust ends when the youngest child reaches a certain age, usually 18 or 21.

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.

Something on a piece of property that attracts children but also endangers their safety. For example, unfenced swimming pools, open pits, farm equipment and abandoned refrigerators have all qualified as attractive nuisances.

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.

An agreement made by a divorcing couple regarding the division of property, custody and visitation of the children, alimony or child support. The agreement must be put in writing, signed by the parties and accepted by the court. It becomes part of the divorce decree and does away with the necessity of having a trial on the issues covered by the agreement. A divorce agreement may also be called a marital settlement agreement, marital termination agreement or settlement agreement.
