Every title insurer, underwritten title company, and controlled escrow company shall file with the commissioner its schedules of rates, all regularly issued forms of title policies to which such rates apply, and every modification thereof which it proposes to use in this state. Every schedule of rates filed by a title insurer shall set forth the entire charge to the public for each type of title policy included within such schedule and shall include without separate statement thereof that portion of the charge, if any, which is based upon work performed by an underwritten title company; there shall be no separate filing by an underwritten title company for such work. Every filing shall set forth its effective date, which shall be not earlier than the 30th day following its receipt by the commissioner, and shall indicate the character and extent of the coverages and services contemplated.
