Does a step-parent have to pay child support?
Whether or not a court will require step-parent child support depends on the state. While traditional common law rules indicated that a step-parent had no duty to support a step-child unless an adoption had taken place, many state legislatures have since passed statutes requiring step-parent support under certain circumstances.
Step-parent Support Requirements
As a general matter, the duty to support a child belongs to his or her parents, even in the event of a divorce. As such, the income of a step-parent is usually not going to be factored in when calculating the child support obligation of the non-custodial parent. However, the courts also recognize that step-parents do have a relationship with their stepchildren by virtue of the marriage to the mother or father of the child.
As such, in many states, there are requirements that step-parents provide child support. In some cases, those requirements do not kick in unless the custodial parents become unable to support the child. For example, under the Delaware Annotated Code Section 13, Chapter 5 section 501(b): "Where the parents are unable to provide a minor child's minimum needs, a step-parent or a person who cohabits in the relationship of husband and wife with the parent of a minor child shall be under a duty to provide those needs. Such duty shall exist only while the child makes residence with such step-parent or person and the marriage or cohabitation continues."
Other states that have statutes requiring a step-parent to provide child support include (but are not limited to) Iowa, Kentucky, Montana, Nebraska, Nevada, Utah, and Washington.
When a step-parent does have an obligation to support a step-child, that duty only exists for the duration of the marriage. In other words, upon divorce, the step-parent will not have to pay child support or have any continuing obligations unless he has adopted the child or signed a marital agreement obliging him to do so.
