Child Support Investigator in Chicago

Supreme Investigations is a licensed child support investigator serving Chicago, Cook County, DuPage County, and all of Chicagoland. Support proceedings often depend on proving what cannot be seen on paper alone. When the calculation turns on what the other parent actually earns — not what they report on a financial affidavit — investigative documentation is the difference. We provide employment verification, hidden income surveillance, lifestyle audits, and attorney-formatted reports prepared for potential use in Illinois income-shares modification proceedings under 750 ILCS 5/505.

Licensed authority for sensitive family matters: Supreme Investigations is licensed by the Illinois Department of Financial & Professional Regulation (IDFPR) under 225 ILCS 447 — Agency #117.001922, Detective #115.002750. All investigations are handled in-house.
