(30 ILCS 550/2) (from Ch. 29, par. 16)
    Sec. 2. Every person furnishing material or performing labor, either as an individual or as a sub-contractor, hereinafter referred to as Claimant, for any contractor, with the State, or a political subdivision thereof where bond or letter of credit shall be executed as provided in this Act, shall have the right to sue on such bond or letter of credit in the name of the State, or the political subdivision thereof entering into such contract, as the case may be, for his use and benefit, and in such suit the plaintiff shall file a copy of such bond or letter of credit, certified by the party or parties in whose charge such bond or letter of credit shall be, which copy shall, unless execution thereof be denied under oath, be prima facie evidence of the execution and delivery of the original; provided, however, that this Act shall not be taken to in any way make the State, or the political subdivision thereof entering into such contract, as the case may be, liable to such sub-contractor, materialman or laborer to any greater extent than it was liable under the law as it stood before the adoption of this Act.
    Provided, however, that any Claimant having a claim for labor and material furnished to the State shall have no such right of action unless it shall have filed a verified notice of said claim with the officer, board, bureau or department awarding the contract, within 180 days after the date of the last item of work or the furnishing of the last item of materials, and shall have furnished a copy of such verified notice to the contractor within 10 days of the filing of the notice with the agency awarding the contract.
    When any Claimant has a claim for labor and material furnished to a political subdivision, the Claimant shall have no right of action unless it shall have filed a verified notice of that claim with the Clerk or Secretary of the political subdivision within 180 days after the date of the last item of work or furnishing of the last item of materials, and shall have filed a copy of that verified notice upon the contractor in a like manner as provided herein within 10 days after the filing of the notice with the Clerk or Secretary.
    The Claimant may file said verified notice by using personal service or by depositing the verified notice in the United States Mail, postage prepaid, certified or restricted delivery return receipt requested limited to addressee only. The verified notice shall be deemed filed on the date personal service occurs or the date when the verified notice is mailed in the form and manner provided in this Section.
    The claim shall be verified and shall contain (1) the name and address of the claimant; the business address of the Claimant within this State and if the Claimant shall be a foreign corporation having no place of business within the State, the notice shall state the principal place of business of said corporation and in the case of a partnership, the notice shall state the names and residences of each of the partners; (2) the name of the contractor for the government; (3) the name of the person, firm or corporation by whom the Claimant was employed or to whom he or it furnished materials; (4) a brief description of the public improvement; (5) a description of the Claimant's contract as it pertains to the public improvement, describing the work done by the Claimant and stating the total amount due and unpaid as of the date of verified notice.
    No defect in the notice herein provided for shall deprive the Claimant of his right of action under this article unless it shall affirmatively appear that such defect has prejudiced the rights of an interested party asserting the same.
    Provided, further, that no action shall be brought later than one year after the date of the furnishing of the last item of work or materials by the Claimant. Such action shall be brought only in the circuit court of this State in the judicial circuit in which the contract is to be performed.
    The remedy provided in this Section is in addition to and independent of any other rights and remedies provided at law or in equity. A waiver of rights under the Mechanics Lien Act shall not constitute a waiver of rights under this Section unless specifically stated in the waiver.
