General Contractor in Idaho. Began job in 2020 with building owner who lives in Arizona , but has roots in Idaho and purchased commercial building several years ago to renovate. I was contracted to provide construction mgmt svcs and trade labor through my company with hourly cost assignments for type of tasks performed. Owner passed away 1 year ago (sudden) and daughter inherited all assets. She was not really involved in father's business and contemplated selling building. Most invoices were paid promptly by father and some items were not billed for yet by me such as some architectural work and carpentry. She decided to keep the building and proceed, however funds were tricky, so we agreed to a weekly draw and would address other payment due for work when building in a more profitable state. Recently, the owner (daughter) has voiced concern that funds are running low and feared that the building completion is at risk. I feel that they may BK or something and I have no protection to be made whole. I am owed for past carpentry work, architectural svcs, materials bought on my construction acct and weekly draws for several weeks. I have not invoiced for work performed prior to passing of her father, but she is aware that work was done and never billed yet. There are receivables due on materials purchased and delivered to site for 2022 (around $13k) and 2023 (not added up yet) and now I want to include past work performed (invoices will be created). I will file a mechanics lien. Just want to make sure within legal rights to bill for other work performed.
