Common Questions

Frequently Asked Questions

Who is this book for?
Anyone who suspects a partner may be unfaithful, or who wants practical, evidence-based guidance instead of pure emotion. It is written for both men and women and is useful whether you are still in the relationship, separated, or already dealing with legal issues.
Does the book teach illegal surveillance or hacking?
No. The focus is on legal observation, documentation, and knowing when and how to hire a licensed professional. Bill Mitchell emphasizes staying within the law so any evidence you gather can actually be used if needed.
Can I hire Mitchell Reports for an infidelity case?

Not for surveillance or field work. The firm now focuses on background checks and locates. The book’s Private Investigators chapter and state licensing list will help you find and vet a licensed investigator near you. If you need a background check or a locate,
