The burden shall be upon the claimant to immediately notify in writing the Director of the Division of Workers' Compensation of any increase or decrease in his income that may affect his eligibility for benefits payable from the "uninsured employer's fund." Ten days after notice has been given to the claimant and the Attorney General, the director may modify or terminate an award payable from the fund as conditions may require. Any payment to a claimant pursuant to this 1988 amendatory and supplementary act which is later determined by the Commissioner of Labor to have been procured by fraud, mistake, or an unreported change in condition, shall be recovered from the claimant and deposited in the fund.
