44-8-26. Collateral real estate mortgages. A mortgage which contains the following statement in printed or typed capital letters: THE PARTIES AGREE THAT THIS MORTGAGE CONSTITUTES A COLLATERAL REAL ESTATE MORTGAGE PURSUANT TO SDCL 44-8-26, is subject to the provisions of this section. A mortgage executed pursuant to this section shall be entitled in printed or typed capital letters: MORTGAGE--COLLATERAL REAL ESTATE MORTGAGE. A mortgage made pursuant to this section shall, notwithstanding the fact that from time to time during the term thereof no indebtedness is due from the mortgagor to the mortgagee, constitute a continuing lien against the real property covered thereby for the amount stated in the mortgage. Any sums not exceeding the face amount of the mortgage, together with interest thereon as provided in the instrument secured by the mortgage, advanced by the mortgagee prior to or during the term of the mortgage have a lien priority as of the date the mortgage was filed. At any time the indebtedness due the mortgagee is zero, the mortgagor may demand in writing that the mortgage be satisfied, and the mortgagee shall within ten days thereafter execute and record a satisfaction thereof. Collateral real estate mortgages may be used to secure commercial, agricultural or consumer loans or lines of credit including, but not limited to, revolving notes and credits and over-draft checking plans.

A filed collateral real estate mortgage is effective for a period of five years from the date of filing and thereafter for a period of sixty days. No sums advanced subsequent to the end of the sixty-day period, save and except sums advanced for protection of the real estate collateral and for real property taxes or insurance, are secured by the collateral real estate mortgage unless an addendum to the collateral real estate mortgage extending its effective date is filed prior to the end of the sixty-day period. An addendum continuing the effectiveness of the collateral real estate mortgage may be filed by the mortgagee within six months before and sixty days after the expiration of the five-year effective date.

An addendum to a collateral real estate mortgage for the sole purpose of continuing the effectiveness of its lien need be signed only by the mortgagee. Upon the timely filing of such an addendum to a collateral real estate mortgage, the effectiveness of the collateral real estate mortgage will be continued for five years and sixty days after the addendum filing date. Thereafter, the addendum shall lose effectiveness to secure sums advanced after the sixty day period to the extent as provided above, unless another addendum to the collateral real estate mortgage continuing the effectiveness of its lien is filed prior to the end of the sixty day period. Succeeding addendums to collateral real estate mortgages may be filed in the same manner to continue the effectiveness of the lien of the collateral real estate mortgage.
