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.

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 child born to your spouse before your marriage whom you have not legally adopted. If you adopt the child, he or she is legally treated just like a biological offspring. Under the Uniform Probate Code, followed in some states, a stepchild belongs in the same class as a biological child and will inherit property left 'to my children.' In other states, a stepchild is not treated like a biological child unless he or she can prove that the parental relationship was established when he or she was a minor and that adoption would have occurred but for some legal obstacle.

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.

The act of freeing someone from restraint or bondage. For example, on January 1, 1863, slaves in the confederate states were declared free by an executive order of President Lincoln, known as the 'Emancipation Proclamation.' After the Civil War, this emancipation was extended to the entire country and made law by the ratification of the thirteenth amendment to the Constitution. Nowadays, emancipation refers to the point at which a child is free from parental control. It occurs when the child's parents no longer perform their parental duties and surrender their rights to the care, custody and earnings of their minor child. Emancipation may be the result of a voluntary agreement between the parents and child, or it may be implied from their acts and ongoing conduct. For example, a child who leaves her parents' home and becomes entirely self-supporting without their objection is considered emancipated, while a child who goes to stay with a friend or relative and gets a part-time job is not. Emancipation may also occur when a minor child marries or enters the military.

The voluntary abandonment of one spouse by the other, without the abandoned spouse's consent. Commonly, desertion occurs when a spouse leaves the marital home for a specified length of time. Desertion is a grounds for divorce in states with fault divorce.

In community property states, property owned and controlled entirely by one spouse in a marriage. At divorce, separate property is not divided under the state's property division laws, but is kept by the spouse who owns it. Separate property includes all property that a spouse obtained before marriage, through inheritance or as a gift. It also includes any property that is traceable to separate property -- for example, cash from the sale of a vintage car owned by one spouse before marriage-and any property that the spouses agree is separate property. Compare community property and equitable distribution.

Any act of inflicting unnecessary emotional or physical pain. Cruelty or mental cruelty is the most frequently used fault ground for divorce because as a practical matter, courts will accept minor wrongs or disagreements as sufficient evidence of cruelty to justify the divorce.
