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.

A court procedure that dissolves a marriage and treats it as if it never happened. Annulments are rare since the advent of no-fault divorce but may be obtained in most states for one of the following reasons: misrepresentation, concealment (for example, of an addiction or criminal record), misunderstanding and refusal to consummate the marriage.

A person who completes all the requirements to legally adopt a child who is not his or her biological child. Generally, any single or married adult who is determined to be a 'fit parent' may adopt a child. Some states have special requirements, such as age or residency criteria. An adoptive parent has all the responsibilities of a biological parent.

A situation in which a famous trademark or service mark is used in a context in which the mark's reputation for quality is tarnished or its distinction is blurred. In this case, trademark infringement exists even though there is no likelihood of customer confusion, which is usually required in cases of trademark infringement. For example, the use of the word Candyland for a pornographic site on the Internet was ruled to dilute the reputation of the Candyland mark for the well-known children's game, even though the traditional basis for trademark infringement (probable customer confusion) wasn't an issue.

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 formal request for a green card or a specific nonimmigrant (temporary) visa. In many cases, the petition must be filed by someone sponsoring the immigrant, such as a family member or employer. After the petition is approved, the immigrant may submit the actual visa or green card application.

The test that courts use when deciding who will take care of a child. For instance, an adoption is allowed only when a court declares it to be in the best interests of the child. Similarly, when asked to decide on custody issues in a divorce case, the judge will base his or her decision on the child's best interests. And the same test is used when judges decide whether a child should be removed from a parent's home because of neglect or abuse. Factors considered by the court in deciding the best interests of a child include: age and sex of the child mental and physical health of the child mental and physical health of the parents lifestyle and other social factors of the parents emotional ties between the parents and the child ability of the parents to provide the child with food, shelter, clothing and medical care established living pattern for the child concerning school, home, community and religious institution quality of schooling, and the child's preference.

A term that most often refers to a lawsuit -- for example, 'I filed my small claims case.' 'Case' also refers to a written decision by a judge -- or for an appellate case, a panel of judges. For example, the U.S. Supreme Court's decision legalizing abortion is commonly referred to as the Roe v. Wade case. Finally, the term also describes the evidence a party submits in support of her position -- for example, 'I have made my case' or ''My case-in-chief' has been completed.'
