When child custody cases are contested, emotions run high and accusations both parties. In many of these highly charged situations, polygraph examination services an impartial and scientific way to verify statements and uncover the truth. A polygraph test, also known as a lie detector test, measures specific physiological responses like blood pressure, respiration, and skin conductivity while a person answers a series of questions.
Polygraphs be useful in a child custody case
Polygraph services provide clarity around several issues that frequently come up in custody battles, including:
- Allegations of abuse or neglect
If one parent accuses the other of physically abusing, emotionally abusing, or neglecting the child, a polygraph gets to the truth of the matter being able to definitively refute false allegations powerful in these cases.
- Suspicions of substance abuse
Substance abuse problems raise major red flags about a parent’s fitness to have physical custody or even liberal visitation with a child. A polygraph exam is used to directly ask parents if they have issues with drugs or alcohol.
- Questions of Infidelity
For better or worse, a parent’s fidelity and faithfulness in their relationship is often viewed as a proxy for their stability as a parent. Polygraph tests detect deception around questions of extramarital affairs.
- Residency and living situation concerns
In many custody disputes, one parent may accuse the other of living in an unsuitable environment for the child, living with an untrustworthy partner, or not residing where they claim. Polygraph questioning reveals the facts.
Polygraph examinations are conducted
Polygraph tests must always be conducted by a trained, certified examiner in a controlled setting designed to limit distractions or interference that could impact the results.

The examiner will go through a pre-test process to explain the procedure, go over the questions that will be asked, and have the subject answer baseline questions to calibrate the polygraph equipment.
Once testing begins, the subject will answer each question verbally with a simple “yes” or “no” while sensors record their physiological responses. The polygraph instrument does not measure deception directly but rather records changes in the person’s breathing, perspiration, cardiovascular activity, and other autonomic responses as they answer each question. The polygraph examiner then analyzes the physiological data from the test to determine if the subject was likely lying or telling the truth on each question. The examiner scores the test data by applying standardized scoring systems and ultimately renders an objective opinion on whether the subject showed signs of deceptive or truthful responses.
Limitations and ethical considerations
While polygraph tests are scientifically valid when properly administered by a qualified examiner, they are not infallible. Issues like certain medical conditions, psychological factors, or countermeasures used by the subject impact the accuracy of the results in some cases. Because of this, most jurisdictions do not allow polygraph evidence to be directly admitted in court.
There are some important ethical concerns to keep in mind regarding the use of polygraphs, particularly when children are involved. Both parents must voluntarily consent to the testing after being fully informed about the process and its implications. Minors under a certain age should not be polygraphed at all, and testing adolescents requires extra caution and safeguards. Polygraph exams should never be used in an unethical way to make a child feel insecure, threatened, or pressured about their living situation or relationship with either parent.
