You might think serving process is straight forward, right? That’s not always the case. Ringing a doorbell repeatedly or pounding on a door doesn’t achieve the results that you really want. Nobody likes bad news, so why escalate the situation further?  We adhere to a robust code of ethics and conduct a thorough screening process to ensure that your legal documents are served with utmost safety, security, and efficiency. We will quickly enter your case, get it to the process server, and turned around in an accurate and timely manner. Typically, we determine service status within four attempts, but for added assurance, we make up to seven attempts at different times of the day.

While we may not be able to explain why individuals cheat or attempt to manipulate systems, Gazelle Process & Investigations is here to assist you in finding resolution to your situation. Surveillance serves as a valuable tool in achieving this goal. Upon completion, we will furnish a detailed chronological report accompanied by video footage and/or photographs, summarizing and documenting our findings.

Our Naperville investigators are skilled in employing diverse interview techniques tailored to civil matters. Moreover, we prioritize creating a comfortable environment for all individuals involved to ensure the utmost accuracy in the statements provided, thereby aiding your case effectively.

Skip Tracing

Skip tracing is an essential tool in our efforts to locate individuals you need to find. This process entails employing a range of information resources to track down individuals who are deliberately evading detection, as well as those who play a pivotal role in legal matters such as lawsuits or estate settlements. We leverage multiple information resources to ensure a swift and precise turnaround in our search efforts.

Civil/Criminal Record Checks

If you need a documents from any court in the state, or documents on file in City Halls, Planning & Zoning Offices etc, you can rely on Gazelle Process & Investigations for the experience needed to do the job right both quickly and accurately. Ask us to retrive your Open Records Acts, FOIAs, Secretary of State documents, Briefs, Complaints, Due Diligence Reports, Motions and Transcripts.

Asset Search

There are many reasons why you might need to conduct an asset search. You may need one for pre-litigation (which is to determine if the subject or company has enough assets to file a lawsuit against them.) Since attorneys can be expensive and the legal process arduous, determining what they have or don’t have can save you thousands of dollars and helps you confirm whether or not the cost of your lawsuit is more than what they have. You might also need an asset search for obtaining a judgment so you can find assets that you can seize.


Cohabitation investigation involves gathering evidence to prove that an individual is living with a partner while claiming to be single, which can be crucial in civil litigation cases involving matters like insurance fraud, alimony disputes, or child support. We can help by conducting thorough investigations, including surveillance, background checks, and interviews, to gather evidence that can strengthen your case in court. Our expertise in uncovering relevant information and presenting it effectively can significantly bolster your position and increase your chances of a favorable outcome in civil litigation proceedings.

I couldn’t recommend Paul more for serving a summons. He was persistent and helped guide us with the process. He had additional resources and was able to serve after the sheriff wasn’t able to.
