Trusted Investigative Services

Surveillance

Our surveillance services provide clear, documented evidence for law firms, insurers, businesses, and private clients across Illinois. We conduct discreet mobile, static, and covert video surveillance to verify activities, confirm claims, and uncover potential fraud while remaining fully compliant with Illinois law. Our investigators capture time-stamped photos, video, and detailed written reports, giving you reliable facts instead of assumptions for negotiations, hearings, and court proceedings. Each case begins with a focused strategy and an operational plan tailored to your objectives, with our team blending seamlessly into any environment while gathering the information you need to move your case forward.

Licensed investigator reviewing asset and credit records for due diligence

Asset & Credit Checks

Our investigation agency provides comprehensive asset and background investigations as well as in-depth personal investigations to help verify assets, credentials, relationships, and personal associations. Whether you're seeking personal due diligence or professional verification, our licensed investigators deliver accurate, confidential results you can trust.

Private detective gathering evidence for alimony and cohabitation investigation

Alimony & Cohabitation

Alimony reduction investigations are often needed when there's a significant change in life circumstances—such as job loss, income reduction, or when a former spouse is cohabitating in violation of court orders. Our experienced Illinois private investigators gather clear, court-admissible evidence and provide a winning strategy to support your case. We deliver the facts you need to help reduce or modify alimony payments legally and effectively.

Child Recovery

Our agency has successfully handled a large number of child abduction cases. Our investigators work tirelessly to locate missing children and return them to their families. Our efforts have been recognized by the National Center for Missing and Exploited Children.

Evidence

Strong cases are built on strong evidence, and our agency excels at gathering, verifying, and documenting the facts your matter depends on. We conduct thorough witness interviews and obtain clear, signed statements that capture key observations and timelines in a professional, court-ready format. Using advanced technology—including digital evidence preservation, GPS data analysis, and social media reviews—we maintain proper chain of custody and deliver secure, cloud-based files that support sound legal and business decisions in injury, fraud, and internal investigations.

Custody & Visitation

The evidence gathered during a child custody investigation provides your attorney with the verified facts needed to make informed recommendations regarding parental fitness and the most suitable custodial parent. Our licensed private investigators deliver objective, court-admissible documentation to help ensure the best outcome for your child's welfare and safety.
