If you are facing a breach of trust in a relationship or a critical legal dispute, the weight of the unknown can be overwhelming. We understand that you aren’t just looking for science, you are searching for a way to move forward with certainty. In Northern California, truth verification has evolved into a streamlined, professional process designed to provide clarity through forensic technology, helping you bridge the gap between suspicion and the truth.
California Lie Detector provides professional examinations across our primary Northern California hubs: Chico/Butte, Vallejo, Redding, and Yuba City. We offer both traditional and modern methods tailored to your specific needs, whether for personal peace of mind or legal preparation.
Truth Verification Disclaimer: As with all non‑polygraph technologies, California Evidence Code 351.1 applies. While our methods are forensically reliable for private truth verification and validated for private use, no method guarantees 100% accuracy.

When deciding how to verify the truth, the best tool depends on your specific situation, your location, and the nature of the dispute.
The polygraph remains the most recognized form of lie detection. It measures multiple physiological markers, heart rate, blood pressure, respiration, and skin conductivity. Because it requires physical sensors attached to the body, it must be conducted in-person at one of our offices in Chico, Vallejo, or Redding. It is ideal for high-stakes legal cases or serious infidelity allegations where physical data is preferred.
Computer Voice Stress Analysis (CVSA) analyzes micro-tremors in the human voice. Unlike the polygraph, there are no wires or sensors attached to your body. This makes it a “voice-based risk assessment tool” that is often more comfortable for the examinee. Because it only requires a high-quality audio feed, it is validated for remote use, making it the most popular choice for clients in Yuba City or Santa Rosa who prefer a video-call format.
Statement Analysis (SCAN) is the process of analyzing the specific words and linguistic patterns used in a written or recorded statement. This method is exceptionally effective for corporate fraud or screening long-form written accounts of events. It can be performed entirely via email or phone, providing a “forensically reliable” layer of analysis without a live confrontation.
One of the most frequent questions we receive from Northern California residents is whether they must travel to an office.
Regardless of the technology used, a professional examination follows a clinical, four-step process to ensure fairness and accuracy.
Generally, per California Evidence Code 351.1, results are not admissible in criminal cases unless all parties stipulate to it. However, they are highly effective “tools for truth” in private matters, family disputes, and as leverage in civil negotiations.
A typical session in our Chico or Vallejo offices lasts about 90 minutes to 2 hours. This includes the pre-test interview, the actual examination, and a post-test data review.
Yes. While a Polygraph requires physical sensors and must be done in person, CVSA and Statement Analysis are validated for remote use. These are excellent options for clients who prefer the comfort of their own home.
We recommend comfortable, non-restrictive clothing. For in-person polygraphs in our NorCal offices, avoid heavy sweaters or bulky jackets that might interfere with the sensor components.
No technology can predict the future. These methods are designed to assess physiological or linguistic stress related to past actions or current knowledge.
