Any individual engaged in the sale of life insurance shall not use the name of any funeral establishment or any price list which identifies the funeral establishment or any reference to a funeral establishment or crematory in connection with the sale of life insurance without the express written authorization of the funeral establishment. When a preneed funeral contract is funded by a life insurance policy, the funeral establishment shall be designated as the assignee of the death benefit payable under the policy in accordance with the terms of the preneed contract.
