Tillson Divorce & Family Law Lawyer, New York

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.

Formerly, statutes governing wills used this phrase to specify children born to married parents, and to exclude those born out of wedlock. Now, the phrase means the same as issue and 'lineal descendant.'

A document used to submit a legal contention or argument to a court. A brief typically sets out the facts of the case and a party's argument as to why she should prevail. These arguments must be supported by legal authority and precedent, such as statutes, regulations and previous court decisions. Although it is usually possible to submit a brief to a trial court (called a trial brief), briefs are most commonly used as a central part of the appeal process (an appellate brief). But don't be fooled by the name -- briefs are usually anything but brief, as pointed out by writer Franz Kafka, who defined a lawyer as 'a person who writes a 10,000 word decision and calls it a brief.'

The entitlement of all children to be supported by their parents until the children reach the age of majority or become emancipated -- usually by marriage, by entry into the armed forces or by living independently. Many states also impose child support obligations on parents for a year or two beyond this point if the child is a full-time student. If the parents are living separately, they each must still support the children. Typically, the parent who has custody meets his or her support obligation through taking care of the child every day, while the other parent must make payments to the custodial parent on behalf of the child -- usually cash but sometimes other kinds of contributions. When parents divorce, the court almost always orders the non-custodial parent to pay the custodial parent an amount of child support fixed by state law. Sometimes, however, if the parents share physical custody more or less equally, the court will order the higher-income parent to make payments to the lower-income parent.

A doctrine that grants the spouse least at fault a divorce when both spouses have shown grounds for divorce. It is a response to an old common-law rule that prevented a divorce when both spouses were at fault.

A person, not necessarily a lawyer, who is appointed by a court to represent and protect the interests of a child or an incapacitated adult during a lawsuit. For example, a guardian ad litem (GAL) may be appointed to represent the interests of a child whose parents are locked in a contentious battle for custody, or to protect a child's interests in a lawsuit where there are allegations of child abuse. The GAL may conduct interviews and investigations, make reports to the court and participate in court hearings or mediation sessions. Sometimes called court-appointed special advocates (CASAs).

A separate court, or more likely a separate division of the regular state trial court, that considers only cases involving divorce (dissolution of marriage), child custody and support, guardianship, adoption, and other cases having to do with family-related issues, including the issuance of restraining orders in domestic violence 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.

An adult who has been given the legal right by a court to control and care for a minor or her property. Someone who looks after a child's property is called a 'guardian of the estate.' An adult who has legal authority to make personal decisions for the child, including responsibility for his physical, medical and educational needs, is called a 'guardian of the person.' Sometimes just one person will be named to take care of all these tasks. An individual appointed by a court to look after an incapacitated adult may also be known as a guardian, but is more frequently called a conservator.
