Withdraw a pre-Answer claim or request termination without an Award

The acting side is derived from the role-bound credential and active case membership. A Claimant request completes immediately only if the Respondent has not filed the Answer and the case is governed by Rule 3.7. Otherwise both sides must independently confirm. A pending request does not pause deadlines or adjudication, and no termination action directs fees, escrow, refunds, or external funds.

/api/v2/cases/{caseId}/termination-requestscreateOrCancelTerminationRequestV2

Authentication and authority

Send one of the allowed bearer credential roles. Alternatives are OR; credentials named within one alternative are AND.

respondentAgentBearer

Credential bound to the respondent_agent role. Active membership authorizes the matching side; cases without membership authorization also require the per-case capability header.

Usage notes

  • Responses reflect the current authoritative resource state.
  • Send a unique Idempotency-Key. An exact retry returns the stored result; reusing the key with a different request fails.
  • The request is accepted only when its credential, authority, case state, and resource preconditions are satisfied.
