When you need skip tracing services in Chicago, IL, Supreme Investigations provides licensed, lawful locate services backed by professional investigative databases and field verification. People become difficult to locate for many reasons — some have moved without a forwarding address, some are actively dodging service of process, and some have simply drifted out of reach over the years. Our goal is to find each individual lawfully and document the result in a written findings report. A licensed Chicago private investigator is not a consumer locate site: we access professional investigative databases beyond typical consumer search tools, we cross-reference findings for accuracy, and we can send someone to physically verify the address before your attorney attempts service. We serve Chicago, Cook County, DuPage County, Naperville, Schaumburg, and all of Chicagoland.

Who We Locate

Absent Parents & Child Support Matters

We locate parents who have stopped paying support, disappeared from custody arrangements, or relocated out of Illinois without notice, and we document the results for enforcement proceedings, contempt filings, and custody modifications in Cook County and Chicagoland family court.

Estranged Relatives & Estate Matters

We find relatives who have lost contact for probate notification, estate distribution, identifying potential heirs in an Illinois probate case, family reconciliation, or any legal proceeding that requires due diligence in locating a family member.

Evasive Defendants & Judgment Debtors

We locate individuals actively avoiding process service, judgment enforcement, subpoenas, or legal contact, then identify and field-verify them before any service attempt so your first attempt succeeds. We clean up stalled Cook County service orders regularly.

Missing Persons (Civil)

We conduct investigative searches for individuals who have lost contact with family, using lawful database research, social media verification, and on-the-ground field confirmation when a paper search alone isn't enough. Each search produces a documented methodology and a usable result.

Documented Case Example

Field Documentation

Locating an Evasive Subject for Process Service — Cook County Family Court Matter

An attorney retained Supreme Investigations after multiple process service attempts at a subject's last known address had failed. The subject had relocated without notice and was actively avoiding legal contact related to a pending family court matter in Cook County.

We began with professional database research — cross-referencing the subject's name, date of birth, and known associates against current address records, utility connections, vehicle registrations, and employment indicators. Within 48 hours, a new residential address had been identified and cross-referenced against multiple independent data sources for accuracy.

Field verification was then deployed to confirm the subject's presence at the location before service was attempted. The process server successfully completed service on the first attempt at the verified address — resolving a matter that had been stalled for over three weeks.

The written findings report provided to the attorney documented the research methodology, the address verification process, and the field confirmation — creating a clear written record of lawful locate and service activity.

Frequently Asked Questions

Most standard skip traces are completed within 48 to 72 hours of engagement. More complex cases — individuals who have deliberately obscured their whereabouts, are using aliases, or have relocated out of state — may require additional research time and field verification. Scope and timeline are confirmed in writing before work begins. Rush turnaround is available for active Cook County court matters and imminent service deadlines.
Database-based skip trace services start at $650, depending on scope, and include a written findings report. Enhanced locate assignments that include field verification to confirm the subject's presence at the identified address start at $850 — this is what we recommend before any process service attempt. All pricing is confirmed in writing before work begins. There are no add-on fees, no mileage charges, and no surprises on delivery.
Yes. Individuals who are actively avoiding contact almost always leave data traces they are unaware of — new utility connections, vehicle registrations, property tax records, employment indicators, and associate cross-references. Professional investigative databases combined with field verification can identify current addresses even when the subject believes they have made themselves difficult to find.
Yes. Skip tracing conducted by a licensed Illinois private investigator using lawful database access is entirely legal. We do not use unauthorized data sources, hacking, social engineering, or pretexting for financial information (which would violate the Gramm-Leach-Bliley Act). Every locate assignment is conducted within Illinois law and applicable federal privacy regulations — because evidence gathered unlawfully is worthless in court.
Yes. We regularly work with family law, civil litigation, collections, and probate attorneys across Cook County, DuPage County, and greater Chicagoland. Our written findings reports are structured for direct use in court filings, affidavits of due diligence, and service documentation. Attorneys may contact us directly to discuss scope, turnaround, and documentation requirements, with no intake coordinator or case manager in between.
