What is the term for a written demand by one of the contracting parties seeking payment of money, adjustment or interpretation of contract terms, or other relief?

The correct term for a written demand by one of the contracting parties seeking payment, adjustment, interpretation of contract terms, or other relief is known as a claim. In the context of contract law and federal acquisition, a claim is a formal assertion or demand for something due, often involving a dispute over the terms of the contract.

When a party feels that they have not been adequately compensated or that there is a need for clarification regarding the contract terms, they will submit a claim that outlines their position and what they are seeking from the other party. This process is crucial in contract management, as it establishes a formal avenue for resolution of disputes and ensures that both parties have a documented record of issues and requests for relief.

The other terms do not encapsulate this concept accurately. A request typically refers to an informal ask for actions or information, not a formal assertion or demand. A notice is often related to informing the other party of certain events or actions, but does not explicitly seek payment or relief as a claim does. A proposal usually refers to an offer to undertake contracted work or provide goods, not a demand arising from existing contractual obligations. Thus, claim is the appropriate term for this situation.
