Cameron Mills Divorce & Family Law Lawyer, New York

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.

A situation in which the partners in a married couple live apart. Spouses are said to be living apart if they no longer reside in the same dwelling, even though they may continue their relationship. A legal separation results when the parties separate and a court rules on the division of property, such as alimony or child support -- but does not grant a divorce.

Time off work for illness. Most employers provide for some paid sick leave, although no law requires them to do so. Under the Family and Medical Leave Act, however, a worker is guaranteed up to 12 weeks per year of unpaid leave for severe or lasting illnesses.

The biological father of a child born to an unmarried couple who has been established as the father either by his admission or by an agreement between him and the child's mother. An acknowledged father must pay child support.

A type of adoption used by agencies to keep a child out of foster care during the adoption process. The child is placed with the adopting parents before the birthmother has legally given up her rights to raise the child. If she then decides not to relinquish her rights, the adopting parents must give the child back. This is a risk for the adopting parents, who may lose a child to whom they've become attached.

Court-ordered care provided to children who are unable to live in their own homes, usually because their parents have abused or neglected them. Foster parents have a legal responsibility to care for their foster children, but do not have all the rights of a biological parent--for example, they may have limited rights to discipline the children, to raise them according to a certain religion or to authorize non-emergency medical procedures for them. The foster parents do not become the child's legal parents unless the biological parents' rights are terminated by a court and the foster parents adopt the child. This is not typically encouraged, as the goal of foster care is to provide temporary support for the children until they can be returned to their parents. See also foster child.

An order from a court directing one person not to do something, such as make contact with another person, enter the family home or remove a child from the state. Restraining orders are typically issued in cases in which spousal abuse or stalking is feared -- or has occurred -- in an attempt to ensure the victim's safety. Restraining orders are also commonly issued to cool down ugly disputes between neighbors.

The taking of a child from his or her parent with the intent to interfere with that parent's physical custody of the child. This is a crime in most states, even if the taker also has custody rights.

A federal law that requires employers to provide an employee with 12 weeks of unpaid leave during a year's time for the birth or adoption of a child, family health needs or personal illness. The employer must allow the employee to return to the same position or a position similar to that held before taking the leave. There are exceptions to the FMLA: the most notable is that only employers with 50 or more employees are covered--about half the workforce.
