Lie detector test for infidelity
When doubt is eating away at a relationship, a polygraph examination can help resolve a specific question objectively. But it only makes sense when it is voluntary for both partners — never as pressure or punishment.
What it can — and can’t — do
The polygraph doesn’t establish facts for you; it tests the consistency of reactions to a clear, specific question. So the key is a concrete issue, not a vague „is he honest”. What the science really supports is explained in how accurate a polygraph is.
Only with consent
The examination is carried out only with voluntary, written consent. A refusal is not proof of anything, and no one should be coerced. This protects both people and keeps the result meaningful.
Discreet and honest
We keep full confidentiality, and the result goes only to the person who ordered it. We never promise „100% certainty” — an inconclusive result is possible, and we say so. For a broader look, see private examinations.

Frequently asked questions
Can it detect infidelity?
It helps resolve a specific, concrete doubt — with consent, and as support for a decision, not a verdict.
Must both partners agree?
The person examined gives their own voluntary consent; no one can be forced.
Is it fully certain?
No — there’s a margin of error and inconclusive results are possible.
