W. Va. Code § 48-18-106

Upon receipt of a report from an employer stating that a support obligor has been discharged or laid off or has resigned or voluntarily quit, the Bureau for Child Support enforcement shall send a notice to the obligor, informing the obligor of the availability of a modification of the support award and of the services that may be available to him or her from the bureau. The bureau shall also inform the obligor of his or her possible entitlement to a reduction in court-ordered support payments; that a failure to obtain a modification will result in the previously-ordered award remaining in effect; and that substantial arrearage might accumulate and remain as judgments against him or her.
