Unless there is an agreement to the contrary, a mortgage granted on an interest-drawing loan shall only secure, with prejudice to a third party, in addition to the principal, interest for the last two years that have elapsed and the part due from the current annual payment.\nNo stipulation may be made in any case that the mortgage secures the interest for more than five years. When a lump sum is established in the deed for interest payments, it may not exceed the amount corresponding to five annual interest payments.\nHistory —Mortgage Law, 1979, § 166.
