There are unpaid change orders (done 3 months ago) on a job that is not finished as well as some retainer money that will be paid on completion of the job. The client and the general contractor are looking to split ways. They brought in an independent auditor. The site has been shut down for 28 days duet to Covid. I was told I need to file a lien within 30 day when job sites are shutdown. Also this is a residential project.
