No portion, split or percentage of any premium shall be paid either directly or indirectly to any person, firm or organization for title insurance, title examination, or determining status of title as set forth above, except a division of premium between an insurer admitted to transact title insurance business in New Mexico and its New Mexico title insurance agency pursuant to their agency agreement, or between New Mexico title insurance agencies (or title insurance agencies who do not have agency agreements in a county where some of the property is located) who are cooperating to close a transaction involving New Mexico property situated in more than one county to be insured in a single policy when each title insurance agency or title insurer is rendering part of the services included in the premiums established in a title rate case. Any title insurance agency who has cancelled its agency agreement or had its agency agreement cancelled by an underwriter may prepare endorsements to existing policies then in force at the time of cancellation upon request by the insured and approval by the underwriter. Any such endorsement shall be signed by an officer of the underwriter. The premium for any such endorsement shall be collected by the cancelled title insurance agent and divided according to the controlling promulgated rates at the time of issuance of the endorsement(s). The payment or receipt of referral fees by or between title insurers or agencies and any person is prohibited.
