Madison Square Divorce & Family Law Lawyer, New York

Any act of inflicting unnecessary emotional or physical pain. Cruelty or mental cruelty is the most frequently used fault ground for divorce because as a practical matter, courts will accept minor wrongs or disagreements as sufficient evidence of cruelty to justify the divorce.

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.

A custody arrangement in the case of multiple children, awarding sole custody of one child to one parent and sole custody of another child to the other parent. This arrangement is generally disfavored by judges because they are reluctant to split up siblings.

Information exchanged between two people who (1) have a relationship in which private communications are protected by law, and (2) intend that the information be kept in confidence. The law recognizes certain parties whose communications will be considered confidential and protected, including spouses, doctor and patient, attorney and client, and priest and confessor. Communications between these individuals cannot be disclosed in court unless the protected party waives that protection. The intention that the communication be confidential is critical. For example, if an attorney and his client are discussing a matter in the presence of an unnecessary third party -- for example, in an elevator with other people present -- the discussion will not be considered confidential and may be admitted at trial. Also known as privileged communication.

An order from a judge that directs a party to come to court and convince the judge why she shouldn't grant an action proposed by the other side or by the judge on her own (sua sponte). For example, in a divorce, at the request of one parent a judge might issue an order directing the other parent to appear in court on a particular date and time to show cause why the first parent should not be given sole physical custody of the children. Although it would seem that the person receiving an order to show cause is at a procedural disadvantage--she, after all, is the one who is told to come up with a convincing reason why the judge shouldn't order something--both sides normally have an equal chance to convince the judge to rule in their favor.

The money paid by one ex-spouse to the other for support under the terms of a court order or settlement agreement following a divorce. Except in marriages of long duration (ten years or more) or in the case of an ailing spouse, alimony usually lasts for a set period, with the expectation that the recipient spouse will become self-supporting. Alimony is also called 'spousal support' or 'maintenance.'

The act of inciting another person to do a particular thing. In a fault divorce, provocation may constitute a defense to the divorce, preventing it from going through. For example, if a wife suing for divorce claims that her husband abandoned her, the husband might defend the suit on the grounds that she provoked the abandonment by driving him out of the house.

The inability of a spouse to engage in sexual intercourse with the other spouse. In some states, physical incapacity is a ground for an annulment or fault divorce, assuming the incapacity was not disclosed to the other spouse before the marriage.
