My favorite uncle was quite a business man, and I googled his will out of curiosity. I found the attorney that his drew his will credited him with 100% of my grandmother’s minerals rather than the 1/8 interest his wife, my aunt, inherited like each of the other seven siblings did. My uncle left all of the minerals to one niece. I filed an Affidavit of Heirship on behalf of my sister and myself. Is this sufficient documentation if anyone wants to lease the minerals and researches the heirs?
