Infidelity Polygraph Testing
Trust is the Fuel to a Healthy Relationship
An infidelity polygraph test is a professionally conducted examination dealing with clearly defined allegations of physical or sexual contact, undisclosed meetings or other specific relationship boundaries.
It is commonly referred to as a lie detector test, but it is not a general test of whether someone is trustworthy or whether they love their partner.
A professional examination must focus on specific, observable conduct within an appropriate period.
Every question is discussed and agreed upon before the test begins.

Questions an Examination May Address
Depending on the circumstances and the agreed relationship boundaries, questions may relate to:
-
Undisclosed sexual contact with another person
-
Physical intimacy outside the relationship
-
A specific alleged encounter
-
Undisclosed meetings with a particular person
-
Relevant communication connected to an alleged affair
-
Conduct during a clearly defined period
-
A specific incident that has caused the breakdown of trust
The final questions are formulated by the examiner after the matter has been assessed. Questions must be clear, fair and suitable for polygraph testing.
What a Polygraph Test Cannot Determine
A polygraph examination cannot:
-
Determine whether someone loves their partner
-
Read a person’s thoughts
-
Test feelings, intentions or private opinions
-
Guarantee future faithfulness
-
Repair the relationship
-
Answer every question about the entire history of a relationship
-
Replace counselling, communication or professional relationship support
The purpose is to provide a professional opinion regarding clearly defined conduct—not to make decisions on behalf of the couple.
Frequently Asked Questions
Does my partner have to consent?
Yes. Every examinee must understand the process and consent to being examined.
Can I arrange a secret test?
No. A professional polygraph examination cannot be conducted without the examinee’s knowledge and participation.
Should both partners undergo testing?
That depends on the allegations and the agreement between the partners. In some matters, one person is examined. In others, both partners choose to be examined separately.
Can I ask as many questions as I want?
The examination should focus on a limited number of important, clearly defined issues. The examiner will help identify which questions are suitable.
Will I know the questions before the test?
Yes. All questions are reviewed with the examinee before physiological data is recorded. Surprise questions are not used.
Can medication affect the examination?
Medication and relevant health information must be disclosed during the suitability assessment. Examinees should continue taking prescribed medication unless advised otherwise by their healthcare professional.
Will the test save our relationship?
The examination may provide information about specific conduct, but it cannot repair trust or decide whether the relationship should continue. Couples may still benefit from appropriate counselling or professional support.
