Why couples take a pre-marital polygraph
Whether you are newly engaged, planning a wedding, or preparing a fiancé visa application, a pre-marital test helps you enter marriage with the doubts settled and the trust confirmed. These are the most common reasons couples come to us.
Confirm whether there has been any sexual contact or emotional affair since the relationship began. For couples rebuilding after a betrayal, an independent test can verify honesty and help restore trust.
Uncover hidden debts, secret accounts, undisclosed spending, or financial commitments a partner has not shared. Financial secrecy is one of the leading sources of conflict in marriage.
Verify there are no concealed relationships, ongoing contact with an ex, or secret communications that a partner has kept private before the commitment.
For international couples and K-1 / fiancé visa contexts, a polygraph can help address doubts about whether the relationship and stated intentions are genuine — testing factual questions about the history of the relationship.
Substance use, prior relationships, or other aspects of a partner’s history they may find difficult to discuss openly. A neutral, structured examination helps both partners feel heard.
Many couples are not in crisis at all — they simply want to begin marriage on a foundation of complete honesty, or to reaffirm trust before taking the next step together.
A polygraph tests the past — not the future
This is the single most important thing to understand before you book. A polygraph measures physiological responses to questions about known facts and events that have already happened. It cannot test feelings, opinions, or promises about what someone will do in the future. Getting this right is what makes your test meaningful.
It tests past and known facts — not future intentions
Only events that have happened, or not happened, can be examined
A polygraph cannot tell you whether your partner will stay faithful, whether they will always love you, or whether they intend to keep a promise. Those are feelings and future intentions — there is no physical fact to measure. What it can do is establish the truth about the history you share: what has, or has not, actually happened up to today.
It tests facts — not feelings or opinions
“Do you truly love me?” is not a polygraph question
Emotions and beliefs have no objective true-or-false answer, so they cannot produce a valid result. Instead, your examiner reframes what you want to know into specific, factual questions. Rather than “Are you hiding money from me?” as a feeling, the question becomes a concrete event you can verify.
Your examiner helps you phrase it right
Well-formed questions are what make the result reliable
You do not need to arrive with perfect wording. During your free, confidential consultation your examiner works with you to turn the concerns that matter into clear yes/no questions grounded in fact — reviewed and agreed with you before testing begins. A single, well-defined issue produces the most accurate result.
Take it individually or as a couple
There is no single right way to do this. Some people book a test for themselves to demonstrate their honesty; others agree to test together. Here is how the two approaches compare — your examiner will help you choose what fits your situation.

Every examination produces one of three outcomes
Knowing what each result means — including inconclusive — helps you set the right expectations before you book.
No Deception Indicated
The physiological data does not indicate deception on the relevant questions. The examinee’s responses are consistent with truthful answers. Commonly referred to as a “pass.”
Deception Indicated
The physiological data suggests deceptive responses to one or more relevant questions. Commonly referred to as a “fail.” The report documents which questions produced the response.
Inconclusive
The data is insufficient to support a definitive finding either way. This is not a fail. It occurs in a minority of examinations, and a retest may be beneficial — at no additional charge if it arose from an examiner or equipment issue.
Suitability is assessed before every test
APA Standards of Practice require examiners to confirm suitability before testing. This is always reviewed during your free consultation — in confidence, and without obligation.

Common questions about pre-marital polygraph testing
Can a polygraph test whether my partner will stay faithful?
No — and it is important to understand why. A polygraph measures physiological responses to questions about facts and events that have already happened. It cannot test the future, feelings, or promises. So it cannot answer “Will you always be faithful?” What it can answer is factual: for example, “Since we met, have you had sexual contact with anyone else?” That gives you the truth about the past, which is what you can actually verify.
Can we both take the test?
Yes. Couples often choose to test together. Each partner takes a separate, individual examination with their own agreed questions. Couples / two-person pricing is available — just ask during your consultation. Each result stays confidential to that examinee unless you both agree to share.
Is it completely confidential?
Yes. Every consultation, examination, and result is strictly confidential. Nothing is shared with anyone — including your partner — without your explicit consent. Our locations are private and discreet, and records are held securely to APA standards.
What kinds of questions can we ask?
Any question grounded in a factual, verifiable event or matter — past infidelity or sexual contact, hidden relationships, undisclosed debts or accounts, substance use, or honesty about the past. Your examiner helps you phrase these as clear yes/no questions during the consultation. Questions about feelings, opinions, or future promises cannot be tested.
Can it help with a foreign-fiancé or K-1 visa case?
It can help address personal doubts about whether a relationship and its history are genuine, by testing factual questions about the relationship. However, a polygraph is not a formal part of the visa adjudication process and is not a substitute for legal advice — treat it as private reassurance, and consult an immigration attorney for anything relating to your application.
Is the process judgmental or confrontational?
Not at all. Our examiners are experienced in emotionally sensitive relationship matters and conduct every test calmly, professionally, and without judgment. Many couples find it a constructive step. Testing should always be voluntary — no one should feel pressured or coerced into taking a test.
How much does it cost, and is there a deposit?
Pricing is all-inclusive and depends on your location and whether one or both partners test. A non-refundable booking deposit (fully refunded if we cannot accept your case or arrange your appointment) — $100 (USD/CAD) or £150 in the UK — secures your appointment and is deducted from the final total. See our pricing page or ask for a confidential quote.
How accurate is it, and when do we get results?
Accuracy is highest when a single, clearly defined issue is tested with well-formed factual questions and an examiner trained to APA standards — the conditions we work to on every test. You receive a same-day verbal result and a written report within 24–48 hours.
