What We Investigate
Eight areas of expertise to answer what you need to know.
Four Reasons Clients Trust Us
Wondering whether you can trust us with your concerns? Here are four commitments that set Trust Research apart.
Court-Ready Evidence
Our investigations are conducted by a team of two or more investigators using professional-grade equipment to capture critical moments with accuracy and discretion. We provide detailed investigation reports that can be used to support negotiations, consultations with legal professionals, and legal proceedings where appropriate.
Transparent Pricing with Written Estimates
Before any investigation begins, we provide a clear written estimate outlining all expected costs. There are no hidden fees and no unexpected charges after the fact. We will recommend a plan that aligns with your objectives and budget.
Strict Confidentiality Guaranteed
We are committed to protecting your privacy. All consultation details and investigation findings are treated as strictly confidential. Confidentiality obligations are clearly defined, and your information is safeguarded throughout every stage of the investigation process.
Dedicated Support Beyond the Investigation
Our support does not end with the delivery of evidence. When needed, we work alongside trusted legal and professional resources to help you navigate the next steps. Your dedicated case manager remains available to provide guidance and support throughout the resolution process.
Don't Let Uncertainty Hold You Back — Get the Answers You Need.
Recently, my partner has been coming home later than usual and has become unusually protective of their phone. I can't stop worrying that they may be having an affair.
I would like to locate a family member or former partner who has become unreachable, but I do not have the means or information to find them myself.
I am experiencing harassment or stalking, but I do not have enough evidence. Even after consulting the police, no action has been taken.
I am considering divorce or seeking compensation, but I do not know how to obtain evidence that will stand up in court.
I have concerns about the background and credibility of a business associate or potential spouse. Before making an important commitment, I would like to confirm the facts.
I do not know who to turn to for help, so I have been carrying these concerns on my own for far too long.
If any of these concerns resonate with you, let us help you find the answers you need. It all starts with a conversation.
