This is not legal advice. Lien deadlines are strict and they change with the contract, the type of project (a home vs. a commercial job), and what the owner records. Public jobs don't take liens at all: you make a bond claim instead. Check the statute we cite, or call a construction lawyer in that state, before you count on a date. Main statute: 770 ILCS 60.
