The previous reply raised some important questions. The most important are what kind of road it is, and what kind of road association you already have. From what you say, I'm guessing it is probably a private road laid out in a subdivision. But do you have a Non-Profit, Statutory, or Informal road association? Section 3121 only applies where there is NO road association already established. That being said, if the one you have is not functioning, you may be better off dissolving it and starting over - but I would recommend a Statutory road association under 23 MRS sections 3101-3104, not a Non-Profit, and not using section 3121.
If you were under the impression an attorney was necessary, I'm guessing you may be in a situation similar to the one my daughter found herself in, where her deed said there was a road association, but it had not actually been formed yet. After she bought the property, the developer brought in an attorney to start a Non-Profit road association, which fizzled within a few years due to lack of participation and inability to enforce payments. They ended up dissolving the non-profit and starting off fresh with a Statutory road association. They now have 50 out of 55 members paying!
You absolutely do not need an attorney to start a Statutory Road Association under section 3101. But you do need to follow the steps in the statutes precisely. If you can possibly do so, I would highly recommend you attend MARA's Annual Conference, which takes place this Saturday, Oct 4th. You can attend via zoom, but you would have to get your application in quickly, as I'm not sure how late they will accept registrations. There will be two attorneys speaking on the formation and operation of a road association, and their advice is invaluable!
If you absolutely cannot attend, the next best thing would be to use the extensive materials on the Resources page of the MARA website. And make good use of the Forum as more questions arise.
