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 divorce automatically granted by a court when the spouse who is served with a summons and complaint for divorce fails to file a formal response with the court. Many divorces proceed this way when the spouses have worked everything out and there's no reason for both to go to court -- and pay the court costs.

Adulthood in the eyes of the law. After reaching the age of majority, a person is permitted to vote, make a valid will, enter into binding contracts, enlist in the armed forces and purchase alcohol. Also, parents may stop making child support payments when a child reaches the age of majority. In most states the age of majority is 18, but this varies depending on the activity. For example, in some states people are allowed to vote when they reach the age of eighteen, but can't purchase alcohol until they're 21.

A legal reason for obtaining either a fault divorce or a no-fault divorce. It is rarely used, however, because of the difficulty of proving both the insanity of the spouse being divorced and that the insanity is incurable.

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.

In some states, a type of marriage in which couples can become legally married by living together for a long period of time, representing themselves as a married couple and intending to be married. Contrary to popular belief, the couple must intend to be married and act as though they are for a common law marriage to take effect -- merely living together for a long time won't do it.

Any divorce in which the spouse who wants to split up does not have to accuse the other of wrongdoing, but can simply state that the couple no longer gets along. Until no-fault divorce arrived in the 1970s, the only way a person could get a divorce was to prove that the other spouse was at fault for the marriage not working. No-fault divorces are usually granted for reasons such as incompatibility, irreconcilable differences, or irretrievable or irremediable breakdown of the marriage. Also, some states allow incurable insanity as a basis for a no-fault divorce. Compare fault divorce.
