Karmi'el Divorce & Family Law Lawyer, Israel

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.

An order from a judge that directs a party to come to court and convince the judge why she shouldn't grant an action proposed by the other side or by the judge on her own (sua sponte). For example, in a divorce, at the request of one parent a judge might issue an order directing the other parent to appear in court on a particular date and time to show cause why the first parent should not be given sole physical custody of the children. Although it would seem that the person receiving an order to show cause is at a procedural disadvantage--she, after all, is the one who is told to come up with a convincing reason why the judge shouldn't order something--both sides normally have an equal chance to convince the judge to rule in their favor.

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.

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.

The formal, legal adoption of a child by a stepparent who is living with a legal parent. Most states have special provisions making stepparent adoptions relatively easy if the child's noncustodial parent gives consent, is dead or missing, or has abandoned the child.

Differences between spouses that are considered sufficiently severe to make married life together more or less impossible. In a number of states, irreconcilable differences is the accepted ground for a no-fault divorce. As a practical matter, courts seldom, if ever, inquire into what the differences actually are, and routinely grant a divorce as long as the party seeking the divorce says the couple has irreconcilable differences. Compare incompatibility; irremediable breakdown.

A mistake by both spouses in a marriage that can serve as grounds for an annulment. For example, if one spouse went into the marriage wanting children while the other did not, they have a misunderstanding that will be judged serious enough for a court to terminate the marriage.

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.

The legal union of two people. Once a couple is married, their rights and responsibilities toward one another concerning property and support are defined by the laws of the state in which they live. A marriage can only be terminated by a court granting a divorce or annulment. Compare common law marriage.
