Illinois Contractor's Affidavit - Individual

What the Illinois Contractor's Affidavit - Individual Is

The Illinois Contractor's Affidavit - Individual is a sworn statement completed by an individual contractor to confirm work performed, payment status, and related project facts for a single contracting party. It typically documents that the contractor provided labor or materials, that invoiced amounts are accurate, and that no undisclosed liens or claims exist. Used in private and public construction projects, the affidavit supports payment requests, lien waivers, or dispute resolution and may be required by owners, general contractors, or payors before releasing funds or processing final project closeout documents.

Why this Affidavit Matters for Contractors and Payors

The affidavit creates a clear, signed record of services and charges, reduces ambiguity for payment processing, and supports lien and payment bond compliance. It helps payors verify claims quickly and contractors to document entitlement to payment in a form commonly accepted across construction workflows.
