And the same test is used when judges decide whether a child should be removed from a parent's home because of neglect or abuse. Factors considered by the court in deciding the best interests of a child include: age and sex of the child mental and physical health of the child mental and physical health of the parents lifestyle and other social factors of the parents emotional ties between the parents and the child ability of the parents to provide the child with food, shelter, clothing and medical care established living pattern for the child concerning school, home, community and religious institution quality of schooling, and the child's preference.

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.
