A case cannot be activated until all mandatory verification requirements have been met for the evidence associated with that case or a current verification waiver exist for the mandatory verification. When a caseworker attempts to activate a case, the Cúram Verification engine is called in order to check that all mandatory verifications associated with active evidence have been satisfied or a current verification waiver exist for the mandatory verification.. If evidence with unsatisfied mandatory verification requirements is found, the Cúram Verification engine prevents the activation of the case and returns an informational message to the caseworker stating that mandatory verification requirements must be satisfied before the case can be activated.
