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.

The entitlement of all children to be supported by their parents until the children reach the age of majority or become emancipated -- usually by marriage, by entry into the armed forces or by living independently. Many states also impose child support obligations on parents for a year or two beyond this point if the child is a full-time student. If the parents are living separately, they each must still support the children. Typically, the parent who has custody meets his or her support obligation through taking care of the child every day, while the other parent must make payments to the custodial parent on behalf of the child -- usually cash but sometimes other kinds of contributions. When parents divorce, the court almost always orders the non-custodial parent to pay the custodial parent an amount of child support fixed by state law. Sometimes, however, if the parents share physical custody more or less equally, the court will order the higher-income parent to make payments to the lower-income parent.

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 lie by one spouse before marriage that provides grounds for an annulment. For example, if a spouse failed to mention that he was still married or was incapable of having children, he has misrepresented himself.

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 type of adoption used by agencies to keep a child out of foster care during the adoption process. The child is placed with the adopting parents before the birthmother has legally given up her rights to raise the child. If she then decides not to relinquish her rights, the adopting parents must give the child back. This is a risk for the adopting parents, who may lose a child to whom they've become attached.

A custody arrangement in the case of multiple children, awarding sole custody of one child to one parent and sole custody of another child to the other parent. This arrangement is generally disfavored by judges because they are reluctant to split up siblings.

A method for defining the ownership of property acquired during marriage, in which all earnings during marriage and all property acquired with those earnings are considered community property and all debts incurred during marriage are community property debts. Community property laws exist in Arizona, California, Idaho, Nevada, New Mexico, Texas, Washington, and Wisconsin. Compare equitable distribution and separate property.

An agreement made by a couple before marriage that controls certain aspects of their relationship, usually the management and ownership of property, and sometimes whether alimony will be paid if the couple later divorces. Courts usually honor premarital agreements unless one person shows that the agreement was likely to promote divorce, was written with the intention of divorcing or was entered into unfairly. A premarital agreement may also be known as a 'prenuptial agreement.'
