N.C. Gen. Stat. § 58-70-80
Whenever the permit of a collection agency is revoked, cancelled, or terminated for any reason, all accounts and valuable papers placed with the agency for collection shall be returned to the person placing the account for collection within five days of the termination of said permit unless, upon written application, an extension of time is granted by the Department of Insurance. All agreements between the collection agency and creditor or forwarder are automatically cancelled as of the date on which said permit is revoked, cancelled or terminated. If any of the accounts placed for collection are in the hands of others at the time of the permit termination, they shall immediately be notified by the collection agency to thereafter correspond, remit and be solely responsible to the creditor placing the accounts with the agency for collection unless the creditor has authorized a successor or other permit holder to continue to collect the accounts. In the case of dissolution of the collection agency, all accounts shall be returned within a reasonable period of time, but in any event not to exceed 60 days. Valuable papers shall include, but not be limited to, notes payable, creditor account cards and any other items placed within the collection agency by the creditor.
