When a deed purporting to be a corrective deed is presented to the county attorney, accompanied by an abstract of title to the land described in the deed, or other evidence deemed satisfactory by the county attorney, the attorney shall examine such deed, abstract, or other evidence presented, upon tender of a fee of $5 therefor. On finding that such deed is given for the purpose of correcting a defect in the title, or on account of a technical error in a prior conveyance, the attorney shall so certify upon the deed; and thereupon the county recorder shall record it, if otherwise entitled to record, notwithstanding that there are unpaid taxes or assessments upon such land.
