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 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.

A doctrine that grants the spouse least at fault a divorce when both spouses have shown grounds for divorce. It is a response to an old common-law rule that prevented a divorce when both spouses were at fault.

The right to see a child regularly, typically awarded by the court to the parent who does not have physical custody of the child. The court will deny visitation rights only if it decides that visitation would hurt the child so much that the parent should be kept away.

A term used by the Uniform Transfers to Minors Act for the person named to manage property left to a child under the terms of that Act. The custodian will manage the property if the gift giver dies before the child has reached the age specified by state law -- usually 21. When the child reaches the specified age, he will receive the property and the custodian will have no further role in its management.

An arrangement by which parents who do not live together share the upbringing of a child. Joint custody can be joint legal custody (in which both parents have a say in decisions affecting the child) joint physical custody (in which the child spends a significant amount of time with both parents) or, very rarely, both.

A court procedure by which an adult becomes the legal parent of someone who is not his or her biological child. Adoption creates a parent-child relationship recognized for all legal purposes -- including child support obligations, inheritance rights and custody.
