The law provides guidelines regarding the minimum amount of child support:

Child support is calculated by adding up all sources of income and making the following deductions:

The duty is to pay child support in an amount sufficient to provide for the reasonable and necessary physical, mental, and emotional health needs of children. The best interest of the child is the governing principle.

Child support may be less than the guidelines if the child resides with the parents on a substantially equal basis, if the non-custodial parent is paying significant expenses for the custodial parent, or if the parents split custody of several children.

Generally, child support must be paid until a child reaches majority.

To determine whether and the amount to award disabled child support or college educational expenses, a court will consider the financial resources of the parents, the standard of living the child enjoyed before the divorce, the financial resources of the child, and the child's academic performance.
