The landlord’s lien for advances shall be indexed in the office of the register of deeds or clerk of the court (when the office of register of deeds does not exist) of the county in which the land is located and the indexing of such lien shall constitute notice thereof to all third persons and entitle the lien to the benefit of this chapter only from the time of such filing for indexing. The index shall show the names of the lienor and lienee, the date and amount of the lien and a brief description of the place so cultivated. And such indexing shall be a sufficient record of the lien and the property covered by such lien, so indexed as aforesaid, if found in the hands of subsequent purchasers or creditors, shall be liable to such lien. The clerk of court or register of deeds, as the case may be, shall endorse his official certificate upon every lien on a crop or crops filed in his office under the provisions of this chapter and his only fee for filing, indexing and certifying such liens shall be fifteen cents for each lien so filed, indexed and endorsed.
