    Key Fact: Illinois

    Illinois does not require a preliminary notice from subcontractors. However, general contractors must provide a sworn statement listing all subcontractors and suppliers.

    Understanding Illinois Requirements

    Illinois does not require a preliminary notice to preserve mechanics lien rights. Under 770 ILCS 60/1, claimants can file a mechanics lien directly within the statutory filing window.

    While no preliminary notice is legally required in Illinois, sending a voluntary notice is considered a best practice. It establishes a paper trail, puts property owners on notice of your involvement, and can help resolve payment disputes before they escalate to lien filing.

    LienFlash is expanding to help contractors in Illinois send voluntary preliminary notices as a payment protection best practice. Even in states without a notice requirement, proactive communication significantly reduces the risk of non-payment.
