Cal. Fin. Code § 28150

A licensee that ceases to service student loans to borrowers shall inform the commissioner in writing and surrender the license and all other indicia of license to the commissioner. The commissioner may require a licensee to file a plan for the disposition of the servicing business that includes, but is not limited to, a closing audit. Upon receipt of the written notice and plan, if required, the commissioner shall determine whether the licensee has violated this division. The commissioner shall give a licensee notice of accepting a surrendered license, and a license shall not be deemed surrendered until the commissioner accepts its tender in writing.
