The right and obligation to make decisions about a child's upbringing, including schooling and medical care. Many states typically have both parents share legal custody of a child. Compare physical custody.

A child born to your spouse before your marriage whom you have not legally adopted. If you adopt the child, he or she is legally treated just like a biological offspring. Under the Uniform Probate Code, followed in some states, a stepchild belongs in the same class as a biological child and will inherit property left 'to my children.' In other states, a stepchild is not treated like a biological child unless he or she can prove that the parental relationship was established when he or she was a minor and that adoption would have occurred but for some legal obstacle.

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 situation set up so that another person commits a wrongdoing. For example, a husband who invites his wife's lover along on vacation may have connived her adultery, and if he tried to divorce her for her behavior, she could assert his connivance as a defense.

A term that most often refers to a lawsuit -- for example, 'I filed my small claims case.' 'Case' also refers to a written decision by a judge -- or for an appellate case, a panel of judges. For example, the U.S. Supreme Court's decision legalizing abortion is commonly referred to as the Roe v. Wade case. Finally, the term also describes the evidence a party submits in support of her position -- for example, 'I have made my case' or ''My case-in-chief' has been completed.'

In the trial court context, a legal proceeding (other than a full-scale trial) held before a judge. During a hearing, evidence and arguments are presented in an effort to resolve a disputed factual or legal issue. Hearings typically, but by no means always, occur prior to trial when a party asks the judge to decide a specific issue--often on an interim basis--such as whether a temporary restraining order or preliminary injunction should be issued, or temporary child custody or child support awarded. In the administrative or agency law context, a hearing is usually a proceeding before an administrative hearing officer or judge representing an agency that has the power to regulate a particular field or oversee a governmental benefit program. For example, the Federal Aviation Board (FAB) has the authority to hold hearings on airline safety, and a state Worker's Compensation Appeals Board has the power to rule on the appeals of people whose applications for benefits have been denied.

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.

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 child placed by a government agency or a court in the care of someone other than his or her natural parents. Foster children may be removed from their family home because of parental abuse or neglect. Occasionally, parents voluntarily place their children in foster care. See foster care.
