Purdin Divorce & Family Law Lawyer, Missouri

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.

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.

A person who initiates a lawsuit. A synonym for plaintiff, used almost universally in some states and in others for certain types of lawsuits, most commonly divorce and other family law cases.

A court judgment that is not final until the judge decides other matters in the case or until enough time has passed to see if the interim decision is working. In the past, interlocutory decrees were most often used in divorces. The terms of the divorce were set out in an interlocutory decree, which would become final only after a waiting period. The purpose of the waiting period was to allow the couple time to reconcile. They rarely did, however, so most states no longer use interlocutory decrees of divorce.

A term used instead of defendant or appellee in some states -- especially for divorce and other family law cases -- to identify the party who is sued and must respond to the petitioner's complaint.

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.
