We are a contractor and I finished the job in Minnesota on August 12, 2021. I am coming close to my 120 days and I would like to file a lien against the property we remodeled. We did not send a preliminary notice at the beginning of the job. We have done several jobs with this customer and never had a problem in the past and did not feel it necessary. However now we are unable to collect our money on the project. Am I still able to file a lien?
