Louisiana Civil Code Tit. XXII, Art. 3298. Mortgage may secure future obligations

A. A mortgage may secure obligations that may arise in the future.

B. As to all obligations, present and future, secured by the mortgage, notwithstanding the nature of such obligations or the date they arise, the mortgage has effect between the parties from the time the mortgage is established and as to third persons from the time the contract of mortgage is filed for registry.

C. A promissory note or other evidence of indebtedness secured by a mortgage need not be paraphed for identification with the mortgage and need not recite that it is secured by the mortgage.

D. The mortgage may be terminated by the mortgagor or his successor upon reasonable notice to the mortgagee when an obligation does not exist and neither the mortgagor nor the mortgagee is bound to the other or to a third person to permit an obligation secured by the mortgage to be incurred.  Parties may contract with reference to what constitutes reasonable notice.

E. The mortgage continues until it is terminated by the mortgagor or his successor in the manner provided in Paragraph D of this Article, or until the mortgage is extinguished in some other lawful manner.  The effect of recordation of the mortgage ceases in accordance with the provisions of Articles 3357 and 3358.
