KEYWORDS: Waiver of Indebtedness DIGEST: Due to an administrative error, an employee was overpaid cost of living allowance (COLA). She was unaware she was being overpaid until she was notified on August 11, 2012. Under 5 U.S.C. § 5584, the amounts the employee received before notification may be waived. However, the amounts she received after notification may not be waived because she did not acquire title to the excess amounts and has a duty to return them to the government.
