(b) Notwithstanding any other provision of law, no court may award or approve prejudgment interest in a domestic relations action against a party unless the court finds, in writing, that the party engaged in conduct that would violate subsection (b), Rule 11 of the West Virginia Rules of Civil Procedure. If prejudgment interest is awarded, the court shall calculate prejudgment interest from the date the offending representation was presented to the court pursuant to subsection (a) of this section.
(c) Upon written agreement by both parties, an obligor may petition the court to enter an order conditionally suspending the collection of all or part of the interest that has accrued on past-due child support prior to the date of the agreement: Provided, That said agreement shall also establish a reasonable payment plan which is calculated to fully discharge all arrearages within twenty-four months. Upon successful completion of the payment plan, the court shall enter an order which permanently relieves the obligor of the obligation to pay the accrued interest. If the obligor fails to comply with the terms of the written agreement, then the court shall enter an order which reinstates the accrued interest.
(d) Amendments to this section enacted by the Legislature during the two thousand six regular session shall become effective the first day of January, two thousand seven.
