What is a means of clearing a certifying officer's pecuniary liability?

A certifying officer can clear their pecuniary liability by demonstrating that the payment in question was made in accordance with applicable laws and regulations, thereby proving that they acted within their authority and followed proper procedures. This can involve providing documentation that supports the legitimacy of the transaction, such as invoices, receipts, and approvals. Additionally, obtaining a waiver or a release from the agency head or relevant authority may also help in clearing any liability.
