"When you need answers — in an infidelity matter, a legal matter, or any situation — you want to know exactly what you're paying for. This guide gives you that, with no ranges and no estimates, so you have total clarity before you begin."

Private investigator pricing reflects the time, skill, equipment, and legal compliance required to produce results that hold up in court. Most agencies aren't transparent about what drives the final invoice — and by the time a client sees the hidden fees, the work is already done.

This page is different. Every rate is published. The tools are built on Supreme Investigations' real 2026 pricing so you can calculate your cost before making any commitment. Se habla español.
