A stepparent also has a legal duty to help support his/her stepchildren until a divorce from the child's parent is final or until there is a court order ending the stepparent's obligation. The parent usually must pay child support monthly. The amount is determined by working through the Washington State Support Schedule.
The Schedule applies to all cases in which child support is ordered, even if the child now lives in another state. The Schedule includes definitions, standards, instructions, and an economic table.
