East Setauket Divorce & Family Law Lawyer, New York

A person, usually a relative, who appears in court on behalf of a minor or incompetent plaintiff, but who is not a party to the lawsuit. For example, children are often represented in court by their parents as 'next friends.'

A special kind of property ownership that's only for married couples. Both spouses have the right to enjoy the entire property, and when one spouse dies, the surviving spouse gets title to the property (called a right of survivorship). It is similar to joint tenancy, but it is available in only about half the states.

A court decision that is intended to prevent harm--often irreparable harm--as distinguished from most court decisions, which are designed to provide a remedy for harm that has already occurred. Injunctions are orders that one side refrain from or stop certain actions, such as an order that an abusive spouse stay away from the other spouse or that a logging company not cut down first-growth trees. Injunctions can be temporary, pending a consideration of the issue later at trial (these are called interlocutory decrees or preliminary injunctions). Judges can also issue permanent injunctions at the end of trials, in which a party may be permanently prohibited from engaging in some conduct--for example, infringing a copyright or trademark or making use of illegally obtained trade secrets. Although most injunctions order a party not to do something, occasionally a court will issue a 'mandatory injunction' to order a party to carry out a positive act--for example, return stolen computer code.

The biological father of a child born to an unmarried couple who has been established as the father either by his admission or by an agreement between him and the child's mother. An acknowledged father must pay child support.

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 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 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.

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.
