1. Do we legally need to file a preliminary notice, to file an Intent to Lien, prior to filing a lien on a property? 2. What right do we have to lien a property without filing a Preliminary Notice? 4. How long are preliminary notices valid for? We found some information that indicated that the preliminary notices are only valid for one year, and that a continuation notice needed to be filed. 5. On the Levelset website, it mentions that the Montana preliminary notices ‘can be filed late’. What does this mean? We have the information from the website, but would like additional information. We do business in Montana, Wyoming, Idaho, Utah, and New York.
