Lie detector in Lisbon: specialist visit or online test today

Questions about the test in Lisbon

• Where can I take a lie detector test in Lisbon?

  We have no office in Lisbon, so there are two options. You can take the VerifEye online test today on your phone, in a quiet room at home or at work. The EyeDetect test takes place during a specialist visit, in your office or a rented room in Lisbon.

• How much does a polygraph test cost in Lisbon?

  VerifEye online test: UAH 2,500 (≈ €49) for one question, UAH 4,000 (≈ €78) for three, UAH 6,000 (≈ €116) for six, with no extra charges. EyeDetect with a visit: from UAH 10,000 (≈ €194) for one question and UAH 15,000 (≈ €291) for three, plus travel from Lviv and the venue. Prices are in hryvnias; euro amounts are approximate, at the NBU rate of 15.09.2026.

• How long is the wait for a visit to Lisbon, and how does it work?

  We plan trips to Portugal once several requests come in from the region, so we cannot tell you in advance how long the wait will be. Once the date is agreed, a specialist comes from Lviv with EyeDetect equipment, and the test takes place in your office or a rented room. If you need an answer sooner, you can take the VerifEye online test today: the test takes 15–20 minutes, and the PDF report comes within 5 minutes after the test.

• How long is the journey to Lisbon and what does a ticket cost?

  The KLR bus leaves Lviv on Wednesdays and reaches Lisbon on Saturday: 65–69 hours by timetable. It is a connecting service, so there is a change on the way. A one-way ticket costs UAH 9,690–10,260 (≈ €188–199), and two suitcases up to 20 kg each are included. The faster option is via Kraków. There are no flights from Lviv, and the closer airport of Rzeszów (≈ 172 km) has no Lisbon route, so we fly from Kraków, about 341 km of road away. The bus from Lviv to Kraków takes 6–10.5 hours by timetable (≈ €23–40 one way). The Ryanair flight to Lisbon takes about 4 hours: a one-way ticket from €33, typically around €84, and more on peak dates. Ryanair charges €29–81 per flight for a 23 kg bag with the equipment if you pay for it when booking. Travel and the venue are paid separately from the test; we will give you the exact round-trip amount once the dates are known.

• Can my partner take a lie detector test for infidelity in Lisbon?

  Yes. The test checks one specific suspicion, for example infidelity over a certain period. The partner under suspicion takes it, or both partners take separate tests. The test is voluntary and requires written consent. The VerifEye online test costs from UAH 2,500 (≈ €49), and you do not need to wait for a visit.

• Can I take the test in Ukrainian in Lisbon?

  Yes. You can take the test in Ukrainian, Russian, English or German. We do not run the test in Portuguese. We draw up the questions together with you, and the person reads them in advance.

• Is a lie detector test legal in Portugal?

  We found no Portuguese law that regulates private lie detector tests. The only law that mentions the polygraph directly is the Framework Law of the Intelligence System (Lei n.º 30/84), article 33.º-B, added by Lei Orgânica n.º 4/2014: security vetting of intelligence staff may include use of the polygraph. A private voluntary test falls under the EU data protection rules (GDPR) and Portugal's Lei n.º 58/2019; the supervisory authority is the National Data Protection Commission (CNPD). We found no CNPD guidance on polygraphs. We test only with written consent, and minors only with written consent from their parents and with the parents present. The rules for testing employees and job candidates are stricter. As a general rule, articles 17 and 19 of the Labour Code forbid an employer to require information about private life or tests and examinations of any nature; the exceptions are narrow and need written justification, and a breach is punished as a very serious offence. So talk to a lawyer before such a test. Portuguese courts treat the lie detector as inadmissible evidence: the Lisbon Court of Appeal said in 2008 that the ban in article 126 of the Code of Criminal Procedure covers the lie detector, and the courts of appeal of Lisbon (2021) and Guimarães (2022 and 2024) list the polygraph among unlawful evidence. The Supreme Court of Justice (Supremo Tribunal de Justiça) refused a review of a conviction in 2017 where a private polygraph report had been attached to the application, and it did not rely on that report. Our result is not court evidence either.
