The legal authority to make decisions affecting a child's interests (legal custody) and the responsibility of taking care of the child (physical custody). When parents separate or divorce, one of the hardest decisions they have to make is which parent will have custody. The most common arrangement is for one parent to have custody (both physical and legal) while the other parent has a right of visitation. But it is not uncommon for the parents to share legal custody, even though one parent has physical custody. The most uncommon arrangement is for the parents to share both legal and physical custody.

The entitlement of all children to be supported by their parents until the children reach the age of majority or become emancipated -- usually by marriage, by entry into the armed forces or by living independently. Many states also impose child support obligations on parents for a year or two beyond this point if the child is a full-time student. If the parents are living separately, they each must still support the children. Typically, the parent who has custody meets his or her support obligation through taking care of the child every day, while the other parent must make payments to the custodial parent on behalf of the child -- usually cash but sometimes other kinds of contributions. When parents divorce, the court almost always orders the non-custodial parent to pay the custodial parent an amount of child support fixed by state law. Sometimes, however, if the parents share physical custody more or less equally, the court will order the higher-income parent to make payments to the lower-income parent.

The situation that occurs in a marriage when one spouse refuses to live with the other and will not work toward reconciliation. In a number of states, irremediable breakdown is the accepted ground for a no-fault divorce. As a practical matter, courts seldom, if ever, inquire into whether the marriage has actually broken down, and routinely grant a divorce as long as the party seeking the divorce says the marriage has fallen apart. Compare incompatibility; irreconcilable differences.

An amount of money available to the surviving spouse and minor or disabled children of a deceased worker who qualified for Social Security retirement or disability benefits.

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.

The legal termination of marriage. All states require a spouse to identify a legal reason for requesting a divorce when that spouse files the divorce papers with the court. These reasons are referred to as grounds for a divorce.

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.

An official count of the number of people living in a certain area, such as a district, city, county, state, or nation. The United States Constitution requires the federal government to perform a national census every ten years. The census includes information about the respondents' sex, age, family, and social and economic status.

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.
