We have already completed an installation and the client owes us a total of $120k which are both overdue. These were two separate invoices, one from November 2022 and one from March 2023. Ther is an additional small piece of work that needs to be completed for the client to have monitoring capabilities, approximately $1k. We have already missed the 90 day window on invoice 1 and 2. Can we file a mechanics lien using the date of the small additional work upon completion to preserve our repayment rights on the total balance that is due to us?
