If an applicant is born out of wedlock, he shall be deemed to possess one-half of the total degree of the mother. Proof of paternity must be filed before the father’s blood can be included when determining the applicant’s degree of Indian blood. If an applicant is claiming membership through the paternal side of the family, proof of paternity must be established. Paternity statements properly notarized, birth certificates signed by the father, findings of a probate examiner, and orders of courts of competent jurisdiction shall be considered as proof of paternity. [Ord. 1 § 10, 1985.]
