Oyster Bay 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 conflict in personalities that makes married life together impossible. In a number of states, incompatibility is the accepted reason for a no-fault divorce. Compare irreconcilable differences; irremediable breakdown.

The formal, legal adoption of a child by a stepparent who is living with a legal parent. Most states have special provisions making stepparent adoptions relatively easy if the child's noncustodial parent gives consent, is dead or missing, or has abandoned the child.

An arrangement by which parents who do not live together share the upbringing of a child. Joint custody can be joint legal custody (in which both parents have a say in decisions affecting the child) joint physical custody (in which the child spends a significant amount of time with both parents) or, very rarely, both.

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.

An official count of the number of people living in a certain area, such as a district, city, county, state, or nation.

The census includes information about the respondents' sex, age, family, and social and economic status.

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.
