For a to-be-owner-occupied residence: May a subcontractor's lien be valid if the IL Notice of Subcontractors Claim/Mechanic's Lien Claim is not prepared or served within 90 days, and, on its face, the alleged last date on which materials were delivered is more than 90 days from the called date on which the Notice was created? What if that same notice also contends certain labor and materials were delivered; but, such labor and materials were indisputably not delivered - potentially through no fault of the subcontract (fault lying with GC)? May a subsequent lien be perfected/enforced?
I am not certain I understand your question, but here is what I believe you are asking:
"Is a Subcontractor's Mechanics Lien valid if perfected more than 90 days after the last labor and materials were delivered?"
Because this area of law, and your question, is so dependent on the facts, I recommend putting together a detailed history and discussing it with an experienced Attorney.
I hope this information was helpful. Best of luck.
