While we strive to be as accurate and complete as possible, our researchers are not attorneys, and state laws are often full of nuances and gaps. Legal challenges in some states have resulted in different registration requirements based on the year of conviction or first registration.

State Laws Regarding Sexual Offenses and Offenders, other than registration

What sexual offenses can people be convicted of, and what are the ranges of sentences?

Does the state have lifetime supervision?

This references it: MCA 46-23-1020(3) Other than that, no indication that Montana has this. I think that by lifetime supervision what is meant is registration.

Are there “Romeo and Juliet” laws or other laws specific to young people?
