Kan. Admin. Regs. § 50-3-7
Claimant's affidavit will be required in support of his or her benefit claim where the listed employer has either failed to verify claimant's alleged wages, previous employment, or where the agency files do not indicate any records or information concerning the listed employer.
The division will utilize the claimant's affidavit in order to make a monetary or nonmonetary determination only if the claimant submits documentary evidence such as, but not limited to, a form W-2, withholding tax statement or a payroll check stub.
When an affidavit is taken, the division representative will explain to the claimant that the determination based on claimant's statement is not final and may be subject to adjustment upon the receipt of information provided by the claimant's listed employer, or other official reports concerning previous employment and separation information.
