Whatever Your Timeline, We've Got a Service to Match

Same-Day Service

Do you have a summons that needs to be served today? Not a problem — we've got you covered.


Whether you have a same-day filing at the Dirksen Federal Building in the Loop, a subpoena that needs to reach someone out by O'Hare Airport, an emergency hearing at the Daley Center on Washington Street, or a last-minute serve in a neighborhood like Pilsen, Bridgeport, or Avondale — Nationwide Investigations dispatches immediately. No runaround, no waiting until tomorrow.

Same-day service means we're on it within hours. We know Chicago's streets, we know the courthouses, and we know how to get it done before your deadline hits.


Call us before Noon for best same-day availability.

Rush Service

Do you have documents that need to be served right away, but same-day isn't quite necessary? Our rush service is exactly what you need.

Simply email us your legal documents and note Rush Service in the subject line. Our Illinois-licensed process servers will make an attempt within 24 hours — and you won't be left wondering. You'll receive a status update as soon as the attempt is made, whether it's a successful serve or a non-service report.


We cover all of Cook County and beyond — from the courthouses in the Loop like the Daley Center and the Dirksen Federal Building, to neighborhoods like Logan Square, Hyde Park, Humboldt Park, and Evanston to the north. If your respondent is near Midway Airport, out in Cicero, or deep in the Southwest Side, we know those streets and we get there.

Routine Service

When your case isn't on an emergency timeline, our routine service gets the job done right. Our trained, Illinois-licensed process servers are out in the field every single day — serving legal documents across Chicago and the surrounding suburbs.


For routine service, we'll make an attempt on your address within 72 hours. It doesn't matter if your summons needs to be served in the Gold Coast, Bridgeview, Beverly, or Berwyn — our servers know these neighborhoods and work them daily. From the North Shore suburbs like Skokie and Niles, down through the Southwest Side to Oak Lawn and Evergreen Park, we've got the coverage to get your documents where they need to go.



Can't locate the respondent at their address? No problem. Our servers are trained to handle difficult serves, and we'll keep you updated every step of the way with a full court-ready affidavit upon completion.

How It Works

Step 1:

Start the process by emailing your legal documents to info@nationwide-investigations.com or submitting through our Secure Portal

Step 2:

Your legal documents will be assigned to a licensed Illinois process server. Depending on the service level they will begin attempting to serve the documents. You will receive email status updates with photos and server notes.

Step 3:

Once your documents are served you will be provided an affidavit to file with the court. In many courts including Cook County Court they require affidavits to be e-filed. We can assist.

FAQs

Got a question? We’re here to help.

  • How Much Does it Cost to Serve Papers?

    The cost of process service depends on the type of service you need and the timeline required, but here's a general breakdown:


    Routine Service — $85.00 flat statewide. Whether your documents need to be served in Chicago's Gold Coast, a suburb like Naperville or Joliet, or downstate in Springfield or Champaign — the price is the same.


    Rush Service — Priced based on urgency and location. Contact us for a quick quote.


    Same-Day Service — Available for emergency serves throughout Chicago and Cook County. Contact us for pricing.


    No hidden fees. No surprises. You'll know the cost upfront before we ever dispatch a server.

    Volume discounts are available for law firms and legal departments with ongoing process serving needs. If your firm handles a high volume of serves across Cook County or statewide, give us a call — we'll put together a package that works for your caseload.

  • Are you Licensed ?

    Yes — Nationwide Investigations is fully licensed through the State of Illinois. Our Illinois Private Detective Agency license number is 117-001790, issued by the Illinois Department of Financial and Professional Regulation (IDFPR).


    In addition to our agency license, our individual process servers are licensed through the State of Illinois as well — so every serve is handled by a credentialed professional, not a contractor pulled off a list.

    We carry our licensing seriously. Illinois is one of the stricter states when it comes to process server regulation, and every member of our team operates in full compliance with the Illinois Code of Civil Procedure. When you work with Nationwide Investigations, your affidavits will hold up in court — whether that's the Cook County Circuit Court at the Daley Center, the Dirksen Federal Courthouse, or anywhere else in the state.

  • How Many Attempts Do you Do?

    We make up to 4 attempts to serve your subject, strategically scheduled at different times of day to maximize the chances of a successful serve. Our process servers don't just show up at the same time every visit — we vary our attempts across mornings, evenings, nights, and weekends to catch the subject when they're most likely to be home.


    Our Illinois-licensed servers use their knowledge of Chicago neighborhoods and surrounding Cook County communities to make smart decisions about timing and approach — whether that's a high-rise in River North, a bungalow on the Southwest Side, or a residence out in the suburbs.


    Have additional information about the subject? Send it over with your documents. Any details help — work schedules, vehicle descriptions, alternate addresses, or known hangout spots. The more we know, the better our chances of a successful serve on the first attempt.

  • What Happens After Service ?

    Once service is complete, you'll receive a court-ready Affidavit of Service documenting the date, time, location, and method of service. If our process server was unable to complete service after all attempts, you'll receive an Affidavit of Non-Service detailing each attempt made — which is equally important for your case record.


    From there, you have two options:


    File it yourself — We'll deliver the affidavit directly to you and your firm can file it with the appropriate court


    We file it for you — Simply authorize us and we'll handle the eFiling on your behalf. We file regularly with the Cook County Circuit Court, the Daley Center, and courts across Illinois — so your proof of service gets where it needs to go without any extra legwork on your end


    All affidavits are prepared to meet Illinois court standards and are accepted by judges across Cook County and the surrounding collar counties.

  • Do you serve outside of Illinois?

    Yes — while Chicago and Cook County are our home base, Nationwide Investigations is a full-service process serving company with the ability to serve legal documents anywhere in the United States.


    Through our trusted network of licensed process servers, we handle out-of-state serves in all 50 states. So whether you need a summons served in Indiana, a subpoena delivered in Wisconsin, or documents served across the country in California or Florida, we have you covered — all coordinated through our Chicago office so you never have to track down a different vendor.


    We're also more than just process serving. As a one-stop shop for legal support, Nationwide Investigations offers:


    Process Serving — Illinois statewide and all 50 states

    Skip Tracing — Locate hard-to-find defendants anywhere in the country
