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.

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.

A document that provides proof of a marriage, typically issued to the newlyweds a few weeks after they file for the certificate in a county office. Most states require both spouses, the person who officiated the marriage and one or two witnesses to sign the marriage certificate; often this is done just after the ceremony.

Latin for 'friend of the court.' This term describes a person or organization that is not a party to a lawsuit as plaintiff or defendant but that has a strong interest in the case and wants to get its two cents in. For example, the ACLU often submits materials to support a person who claims a violation of civil rights even though that person is represented by a lawyer.

A lawsuit to determine the identity of the father of a child born outside of marriage, and to provide for the support of the child once the identity of the father has been determined.

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.

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.
