Required forms are available through the CDIB office.

Other Information

The Certificate of Degree of Indian Blood (CDIB) application is for applicants who want to prove their Chickasaw Indian blood. The application is a family tree chart that must be submitted with birth certificates or death certificates, and supporting documents if needed.

Once the application is received in the CDIB office, the research begins by looking up the enrolled ancestors on the Dawes Commission Rolls, which are the base rolls for the Five Civilized Tribes.

The CDIB does not establish citizenship with the Chickasaw Nation. Once applicants receive the CDIB, they are eligible for citizenship in the Chickasaw Nation.
