Sex Offender Registration and Notification Act (SORNA)

The Tribes’ commitment to implement Title 1 of the Adam Walsh Act known as the Sex Offender Registration and Notification Act (SORNA) dates back to tribal legislation, Electing to Participate in the National Sex Offender Registry System that was approved in 2007. The Tribes Governor Janice Boswell signed the Tribes Sex Offender Code into law August 27, 2012. On July 23, 2013, the Tribes Sex Offender Registry Program registered a sex offender for the first time. In July 2014, amendments were made to the Code and the Sex Offender Registration Act was signed into law by Governor Eddie Hamilton.

All sex offenders who reside, are employed, or are a student within the lands subject to tribal jurisdiction must register with the Sex Offender Registry Program. In these types of cases, sex offenders must register and keep the registration current. Additionally, all sex offender convicted by the Tribes of a covered sex offense must register. In these types of cases, sex offenders must initially register with the Tribes regardless of the sex offender’s actual or intended residency.

Each registered sex offender appears in person to keep registration current based on the level at which the person has been tiered.

Tiering is as follows:

  1. Tier 1 sex offenders appear once a year for 15 years;
  2. Tier 2 sex offenders appear once every 180 days for 25 years,
  3. Tier 3 sex offenders appear once every 90 days for the life.

The Tribes collaborate with US Marshals, BIA Law Enforcement, and surrounding counties to enforce the Tribal Sex Offender Registration Act.
