How to Prepare
For Attorneys
- Research polygraph admissibility rules in your jurisdiction before proceeding
- Provide case summary, relevant discovery, and specific questions you want answered
- Discuss with your client the voluntary nature and potential risks/benefits
- Consider timing—polygraphs work best before depositions or plea negotiations
- Understand results may not always support your client's position
For Your Client
- Counsel them to get adequate sleep (8+ hours) the night before
- Avoid caffeine, nicotine, or alcohol for 4 hours before examination
- Advise them to answer all questions completely truthfully
- Explain they should disclose any medical conditions or medications
- Remind them cooperation and calm demeanor produce best results
Important Consideration
Polygraph examinations are voluntary. If results are unfavorable, opposing counsel may discover that a test was conducted. Consider stipulating results in advance or using polygraph strategically in plea negotiations rather than at trial. We can advise on best practices for your jurisdiction.
Understanding Results
No Deception Indicated (NDI)
Physiological responses consistent with truthfulness. Strengthens your client's position in negotiations, supports innocence claims, or corroborates witness statements.
Strategic use: Powerful tool for plea negotiations, settlement discussions, or demonstrating good faith investigation to prosecutors.
Deception Indicated (DI)
Significant physiological responses suggesting deception. May require reassessment of case strategy, client counseling, or exploring plea options.
Note: These results are generally not discoverable unless you choose to disclose them or they were stipulated in advance. Discuss confidentiality protections with the examiner.
Inconclusive
Results don't clearly indicate deception or truthfulness. Can result from extreme anxiety, medical conditions, countermeasures, or ambiguous questions.
Options: Retest with modified questions, consider alternative investigation methods, or focus on other evidence. Inconclusive results rarely help or hurt your case significantly.
Admissibility & Limitations
Court Admissibility: Polygraph admissibility varies by jurisdiction and context. In Alabama, Louisiana, Mississippi, and Florida, results are generally not admissible at trial unless stipulated by both parties or in specific circumstances (e.g., some post-conviction proceedings). Judges have discretion.
Strategic Value: Even when inadmissible, polygraph results can be powerful negotiation tools, help prosecutors make charging decisions, support bail arguments, or convince opposing counsel to settle.
Not Absolute Proof: Polygraphs are investigative tools, not infallible truth detectors. Results should support—not replace—traditional evidence like documents, witnesses, and forensics.
Legal Consultation Required: Always consult with the attorney of record before using polygraph evidence in court proceedings. We provide expert opinion on results but do not provide legal advice.
Attorney-Client Confidentiality
We understand attorney-client privilege and work-product doctrine:
- All communications with attorneys are confidential and covered under work-product
- Results released only to the retaining attorney unless otherwise authorized
- We do not disclose the existence of an examination without attorney authorization
- Records maintained securely and destroyed per retention schedule or attorney request
- Retainer agreements clearly define scope of confidentiality and reporting obligations
