So long as an employee or statutory dependent pursuant to § 65.2-515 receives payment of compensation under this title, any such person shall have a duty immediately to disclose to the employer, when the employer is self-insured, or insurer in all other cases, any incarceration, return to employment, increase in his earnings, remarriage or change in his status as a full-time student. Any payment to a claimant by an employer or insurer which is later determined by the Commission to have been procured by the employee or statutory dependent under § 65.2-515 by fraud, misrepresentation, or failure to report any incarceration, return to employment, increase in earnings, remarriage or change in his status as a full-time student may be recovered from the claimant or statutory dependent by the employer or insurer either by way of credit against future compensation payments due the claimant or statutory dependent, or by action at law against the claimant or statutory dependent. The Commission shall provide for notification to the statutory dependent of his obligation under this section.
