Missouri Revised Statutes Title XXIV. Business and Financial Institutions § 379.090. Premium notes, how payable

1. Every person who shall insure in such mutual company, whose premium is payable by note, shall, before he receives his policy, deposit with the company a note for such sum or sums of money as may be agreed upon for the premium, a part, not less than ten percent of which, shall be immediately paid in cash before the company shall be liable for any loss; and the remainder of said note shall be made payable at any time, and in part or the whole as the directors of said company may demand, upon an assessment to be made by them whenever they shall deem the same necessary, for the payment of losses, expenses and other liabilities of said company; said note, or such part thereof as shall remain unpaid at the expiration or termination of the policy, shall be given up to the maker of the same, provided all assessments upon such note and all liabilities of said maker to the company shall have been paid.

2. All buildings and other property, real and personal, insured by and with such company, together with all right, title and interest of the insured to the lands on which such buildings are situated, shall be pledged to such company, and the company shall have a lien thereon until the aforesaid note is fully paid; provided, that the maker of said note shall assent to such lien in writing upon the face of the same.
