Which of the following best defines the term “expired” in relation to sex offender registration?

The term "expired" in relation to sex offender registration best aligns with the definition of "no longer valid." This implies that the registration is no longer active and may no longer meet legal requirements or obligations. In the context of sex offender laws, registrations are typically time-sensitive and may have specific durations during which the offender must remain registered. Once that period lapses without renewal or compliance, the registration status can be considered expired.

Maintaining accurate and current information is crucial for public safety, which is why an expired registration is treated as a situation requiring immediate attention, as it could lead to legal repercussions for the offender and potential safety risks for the community.
