An affidavit may be used as a means of correcting discrepancies and variances in names and in other cases where it may be accepted as curative evidence under South Dakota statute. It should include some showing that the material statements in it are based on affiant's personal knowledge. The value of an affidavit is not diminished by the fact that the maker is interested in the title or the subject matter of the affidavit, when nothing appears in the record to affect maker's credibility.
