Tisch Mills Divorce & Family Law Lawyer, Wisconsin

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.

An investigation of prospective adoptive parents to make sure they are fit to raise a child, required by all states. Common areas of inquiry include financial stability, marital stability, lifestyles and other social factors, physical and mental health and criminal history.

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.

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.

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.

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 court decision that is intended to prevent harm--often irreparable harm--as distinguished from most court decisions, which are designed to provide a remedy for harm that has already occurred. Injunctions are orders that one side refrain from or stop certain actions, such as an order that an abusive spouse stay away from the other spouse or that a logging company not cut down first-growth trees. Injunctions can be temporary, pending a consideration of the issue later at trial (these are called interlocutory decrees or preliminary injunctions). Judges can also issue permanent injunctions at the end of trials, in which a party may be permanently prohibited from engaging in some conduct--for example, infringing a copyright or trademark or making use of illegally obtained trade secrets. Although most injunctions order a party not to do something, occasionally a court will issue a 'mandatory injunction' to order a party to carry out a positive act--for example, return stolen computer code.

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.
