(1) For an adult convicted in this state of a class A felony, or an adult convicted of any sex offense or kidnapping offense who has one or more prior convictions for a sex offense or kidnapping offense, the duty to register shall continue indefinitely.

(2) For an adult convicted in this state of a class B felony who does not have one or more prior convictions for a sex offense or kidnapping offense, the duty to register shall end fifteen years after the last date of release from confinement, if any, (including full-time residential treatment) pursuant to the conviction, or entry of the judgment and sentence, if the adult has spent fifteen consecutive years in the community without being convicted of a disqualifying offense during that time period.

(3) For an adult convicted in this state of a class C felony, a violation of RCW 9.68A.090 or 9A.44.096, or an attempt, solicitation, or conspiracy to commit a class C felony, and the adult does not have one or more prior convictions for a sex offense or kidnapping offense, the duty to register shall end ten years after the last date of release from confinement, if any, (including full-time residential treatment) pursuant to the conviction, or entry of the judgment and sentence, if the adult has spent ten consecutive years in the community without being convicted of a disqualifying offense during that time period.

(5) Except as provided in RCW 9A.44.142, for a person required to register for a federal, tribal, or out-of-state conviction, the duty to register shall continue indefinitely.

(6) For a person who is or has been determined to be a sexually violent predator pursuant to chapter 71.09 RCW, the duty to register shall continue for the person's lifetime.

(7) Nothing in this section prevents a person from being relieved of the duty to register under RCW 9A.44.142, 9A.44.143, and 13.40.162.

(8) Nothing in RCW 9.94A.637 relating to discharge of an offender shall be construed as operating to relieve the offender of his or her duty to register pursuant to RCW 9A.44.130.

(9) For purposes of determining whether a person has been convicted of more than one sex offense, failure to register as a sex offender or kidnapping offender is not a sex or kidnapping offense.
