(a) A claim is a written demand by one of the contracting parties, asking for one or more of the following:
(1) Payment of a specific sum of money under the contract;
(2) Adjustment or interpretation of contract terms; or
(3) Any other claim relating to the contract.
(b) However, an undisputed voucher, invoice, or other routing request for payment is not a claim under the CDA. A voucher, invoice, or routing request for payment may be converted into a CDA claim if:
(1) It is disputed as to liability or amount; or
(2) It is not acted upon in a reasonable time and written notice of the claim is given to the awarding official by the senior official designated in the contract.
