A child placed by a government agency or a court in the care of someone other than his or her natural parents. Foster children may be removed from their family home because of parental abuse or neglect. Occasionally, parents voluntarily place their children in foster care. See foster care.

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.

Consensual sexual relations by a married person with someone other than his or her spouse. In many states, adultery is technically a crime, though people are rarely prosecuted for it. In states that have retained fault grounds for divorce, adultery is always sufficient grounds for a divorce. In addition, some states alter the distribution of property between divorcing spouses in cases of adultery, giving less to the 'cheating' spouse.

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 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.

Secret cooperation between two people in order to fool another. Collusion was often practiced by couples before no-fault divorce in order to make up a grounds for divorce (such as adultery). By fabricating a permitted reason for divorce, colluding couples hoped to trick a judge into granting their freedom from the marriage. But a spouse accused of wrongdoing who later changed his or her mind about the divorce could expose the collusion to prevent the divorce from going through.

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 document that provides proof of a marriage, typically issued to the newlyweds a few weeks after they file for the certificate in a county office. Most states require both spouses, the person who officiated the marriage and one or two witnesses to sign the marriage certificate; often this is done just after the ceremony.
