There have been 2013 changes to the statute that may affect your road association. I will post separately three documents: the revised statute, a sample claim form that you can file with your Registry of Deeds for claiming unpaid assessments at the time of the property's next sale, and a sample road association bylaws. See topics "2013 Maine statute revisions," "Sample Bylaws," and "Notice of Claim."
You may also go to the maine.gov online statute:

and scroll through sections 33101-3105.
