An immediate family member of someone who immigrates to the United States. In most cases, a person who is eligible to receive some type of visa or green card can also obtain green cards or similar visas for accompanying relatives. Accompanying relatives include spouses and unmarried children under the age of 21.

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.

Latin for 'friend of the court.' This term describes a person or organization that is not a party to a lawsuit as plaintiff or defendant but that has a strong interest in the case and wants to get its two cents in. For example, the ACLU often submits materials to support a person who claims a violation of civil rights even though that person is represented by a lawyer.

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 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 parent's failure to provide any financial assistance to or communicate with his or her child over a period of time. When this happens, a court may deem the child abandoned by that parent and order that person's parental rights terminated. Abandonment also describes situations in which a child is physically abandoned -- for example, left on a doorstep, delivered to a hospital or put in a trash can. Physically abandoned children are usually placed in orphanages and made available for adoption.

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.

Someone appointed by a court to care for the property of a minor child that is not supervised by an adult under some other legal method, such as a trust. A guardian of the estate may also be called a 'property guardian' or 'financial guardian.' See also guardian.
