Common Reasons People Request a Polygraph
People request polygraph testing through Eye Spy for a range of personal situations:
- Verifying whether a partner is being faithful or has been in the past
- Resolving a personal dispute where one person’s account contradicts another’s
- Addressing concerns about drug use or other behavior within a family
- Gaining personal clarity in a situation where the truth matters, even if it won’t be used in a legal proceeding
What a Polygraph Can and Can’t Do
A polygraph can give you a professional, structured assessment of truthfulness on specific questions. What it can’t do is serve as legal proof. Michigan courts – both criminal and civil – do not admit polygraph results as evidence, under a rule the Michigan Supreme Court established in People v. Barbara (1977) and has upheld consistently since.
This matters most if you’re facing an actual criminal accusation. If that’s your situation, talk to a criminal defense attorney before scheduling a polygraph, not after. Two reasons: a favorable result can’t be used to clear your name in court, and anything you say during the exam – including any admission – can potentially be used against you, separate from the test results themselves. A polygraph taken without legal guidance in a criminal matter can create risk without any corresponding legal benefit.
For personal, relationship, or non-legal matters, none of this applies the same way – a polygraph can still offer real clarity and peace of mind even though it isn’t admissible in court.
Confidentiality
Eye Spy is a licensed Michigan private investigation firm, and Michigan’s Professional Investigator Licensure Act (MCL 338.840) provides meaningful confidentiality protection for what you discuss with us and the investigative work we perform. Testing is conducted privately in our office, and results are shared only with you and whoever you authorize.
If your situation involves active criminal exposure, ask your attorney how that protection interacts with anything said directly to the polygraph examiner during the exam itself – that’s a more specific legal question than general investigator-client confidentiality covers, and it’s worth getting a straight answer before you test, not after.

Common Questions About Polygraph Services in Michigan
Where does Eye Spy conduct polygraph testing?
All polygraph testing is conducted in person at Eye Spy’s office in Fraser, MI. Testing is done privately in a professional setting – not in a home, vehicle, or other informal location.
Who administers the polygraph exam?
Every exam is administered by a Michigan-licensed polygraph examiner who has conducted thousands of tests. Eye Spy does not use outside contractors for polygraph services – the examiner is part of the firm.
Who receives the polygraph results?
Results are shared only with you and whoever you authorize to receive them. Eye Spy is a licensed Michigan private investigation firm, and your case is protected under Michigan’s Professional Investigator Licensure Act (MCL 338.840) – results are not disclosed to anyone without your authorization.
Can polygraph results be used in a Michigan divorce or child custody case?
Not directly. Michigan courts do not admit polygraph results as evidence in criminal or civil proceedings, under a rule established in People v. Barbara (1977). That said, a polygraph can still be useful in a family law context – as a tool for your own clarity, or as leverage in negotiation outside of court. Talk to your attorney about how it fits your specific situation.
