(a) An expedited process for modification of a child support order may be utilized if:

(1) Either parent experiences a substantial change of circumstances resulting in a decrease in income due to loss of employment or other involuntary cause;

(2) An increase in income due to promotion, change in employment or reemployment;

(3) Other such change in employment status; or

(4) If a military parent is called to military service.

(b) The party seeking the recalculation of support and modification of the support order shall file a description of the decrease or increase in income and an explanation of the cause of the decrease or increase on a standardized form to be provided by the secretary-clerk or other employee of the family court. The standardized form shall be verified by the filing party. Any available documentary evidence shall be filed with the standardized form. Based upon the filing and information available in the case record, the amount of support shall be tentatively recalculated.

(c) The secretary-clerk shall serve a notice of the filing, a copy of the standardized form and the support calculations upon the other party by certified mail, return receipt requested, with delivery restricted to the addressee, in accordance with rule 4(d)(1)(D) of the West Virginia rules of civil procedure. The secretary-clerk shall also mail a copy, by first-class mail, to the local office of the Bureau for Child Support enforcement for the county in which the family court is located in the same manner as original process under rule 4(d) of the rules of civil procedure.

(d) The notice shall fix a date fourteen days from the date of mailing and inform the party that unless the recalculation is contested and a hearing request is made on or before the date fixed, the proposed modification will be made effective. If the filing is contested, the proposed modification shall be set for hearing; otherwise, the court shall enter an order for a judgment by default. Either party may move to set aside a judgment by default, pursuant to the provisions of rule 55 or rule 60(b) of the rules of civil procedure.

(e) If an obligor uses the provisions of this section to expeditiously reduce his or her child support obligation, the order that effected the reduction shall also require the obligor to notify the obligee of reemployment, new employment or other such change in employment status that results in an increase in income. If an obligee uses the provisions of this section to expeditiously increase his or her child support obligation, the order that effected the increase shall also require the obligee to notify the obligor of reemployment, new employment or other such change in employment status that results in an increase in income of the obligee.

(f) The Supreme Court of Appeals shall develop the standardized form required by this section.
