Moreau Divorce & Family Law Lawyer, New York

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 method for defining the ownership of property acquired during marriage, in which all earnings during marriage and all property acquired with those earnings are considered community property and all debts incurred during marriage are community property debts. Community property laws exist in Arizona, California, Idaho, Nevada, New Mexico, Texas, Washington, and Wisconsin. Compare equitable distribution and separate property.

A person, usually a relative, who appears in court on behalf of a minor or incompetent plaintiff, but who is not a party to the lawsuit. For example, children are often represented in court by their parents as 'next friends.'

A person, not necessarily a lawyer, who is appointed by a court to represent and protect the interests of a child or an incapacitated adult during a lawsuit. For example, a guardian ad litem (GAL) may be appointed to represent the interests of a child whose parents are locked in a contentious battle for custody, or to protect a child's interests in a lawsuit where there are allegations of child abuse. The GAL may conduct interviews and investigations, make reports to the court and participate in court hearings or mediation sessions. Sometimes called court-appointed special advocates (CASAs).

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.

The legal union of two people. Once a couple is married, their rights and responsibilities toward one another concerning property and support are defined by the laws of the state in which they live. A marriage can only be terminated by a court granting a divorce or annulment. Compare common law marriage.

An agreement made by a couple before marriage that controls certain aspects of their relationship, usually the management and ownership of property, and sometimes whether alimony will be paid if the couple later divorces. Courts usually honor premarital agreements unless one person shows that the agreement was likely to promote divorce, was written with the intention of divorcing or was entered into unfairly. A premarital agreement may also be known as a 'prenuptial agreement.'

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 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.
