A person who supports and maintains, in one household, one or more people who are closely related to him by blood, marriage or adoption. Under federal income tax law, you are eligible for favorable tax treatment as the head of household only if you are unmarried and you manage a household which is the principal residence (for more than half of the year) of dependent children or other dependent relatives. Under bankruptcy homestead and exemption laws, the terms householder and 'head of household' mean the same thing. Examples include a single woman supporting her disabled sister and her own children or a bachelor supporting his parents. Many states consider a single person supporting only himself to be a head of household as well.

A court procedure by which an adult becomes the legal parent of someone who is not his or her biological child. Adoption creates a parent-child relationship recognized for all legal purposes -- including child support obligations, inheritance rights and custody.

A lawsuit to determine the identity of the father of a child born outside of marriage, and to provide for the support of the child once the identity of the father has been determined.

A situation in which the partners in a married couple live apart. Spouses are said to be living apart if they no longer reside in the same dwelling, even though they may continue their relationship. A legal separation results when the parties separate and a court rules on the division of property, such as alimony or child support -- but does not grant a divorce.

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.'

A legal principle, followed by most states, under which assets and earnings acquired during marriage are divided equitably (fairly) at divorce. In theory, equitable means equal, but in practice it often means that the higher wage earner gets two-thirds to the lower wage earner's one-third. If a spouse obtains a fault divorce, the 'guilty' spouse may receive less than his equitable share upon divorce.

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.
