Gaslighting is not illegal as a named offense anywhere in the United States, but the question of whether gaslighting is illegal has a more useful answer: the behaviors that make up gaslighting routinely violate existing laws. Depending on the setting, sustained psychological manipulation can support criminal charges, civil lawsuits for damages, protective orders, custody changes, and workplace discrimination claims. A handful of states have gone further and criminalized coercive control, which captures much of what gaslighting looks like in practice.
Criminal Laws That Reach Gaslighting Behavior
No police department will take a report of “gaslighting.” They will take a report of harassment, stalking, criminal threats, or criminal coercion, and the conduct behind a gaslighting pattern often fits one of those offenses. The common thread is a sustained course of conduct that causes fear or distress, rather than a single incident. State definitions vary, so what qualifies in one jurisdiction may fall short in another.
Several states have enacted coercive control laws that target this kind of behavior more directly. These statutes criminalize patterns of conduct designed to restrict another person’s freedom or autonomy through isolation, deceit, monitoring, and control over finances or outside support. The word “gaslighting” does not appear in any of them, but the sustained psychological manipulation they describe is the same thing. Penalties range up to jail time, and the conduct can also serve as grounds for a protective order.
Federal Witness Tampering
Gaslighting someone into doubting what they witnessed can be a federal crime when it is done to interfere with testimony. Under 18 U.S.C. § 1512, using “misleading conduct” to influence, delay, or prevent a person’s testimony in an official proceeding carries up to 20 years in prison.1Office of the Law Revision Counsel. 18 USC 1512 – Tampering With a Witness, Victim, or an Informant
The statutory definition of “misleading conduct” is broad. It covers knowingly false statements, intentional omissions that create a false impression, and any “trick, scheme, or device with intent to mislead.”2GovInfo. 18 USC 1515 – Definitions for Certain Provisions Convincing a witness their memory is wrong, that an event never happened, or that they misunderstood what they saw fits within that definition when the goal is to interfere with a legal proceeding.
Elder Abuse
Most states define elder abuse to include emotional and psychological harm, not only physical violence. Making an older adult doubt their memory to gain control of their finances, isolating them by distorting what relatives supposedly said, or repeatedly undermining their confidence to increase dependence can qualify as abuse. Penalties range from misdemeanors to felonies depending on severity and state.
Gaslighting as Domestic Violence
The U.S. Department of Justice recognizes psychological abuse as a form of domestic violence. Its definition includes “causing fear by intimidation,” “forcing isolation from family, friends, or school and/or work,” and other “patterns of coercive behavior that influence another person within an intimate partner relationship.”3U.S. Department of Justice Office on Violence Against Women (OVW). Domestic Violence Gaslighting fits within that framework because it operates through psychological control.
This matters in two concrete ways. In most jurisdictions, a victim can seek a protective or restraining order by showing a pattern of emotional or psychological abuse, without proving physical violence. Such orders can require the abuser to stay away, stop all contact, and leave a shared residence. In states that have incorporated coercive control into their domestic violence frameworks, courts can also weigh psychological manipulation when deciding whether domestic violence occurred, even without a separate coercive control crime on the books.
Suing for Gaslighting
Victims can sue for money damages, most often through a claim called intentional infliction of emotional distress. The bar is high. The plaintiff has to prove four things: the defendant’s conduct was extreme and outrageous, the defendant acted intentionally or recklessly, the conduct caused the plaintiff’s distress, and the distress was severe.
“Extreme and outrageous” means more than rude, hurtful, or even cruel. Courts have described it as conduct beyond all bounds of decency that a reasonable person would find intolerable. A single incident of dishonesty rarely clears the bar. What can clear it is a pattern. Months or years of sustained reality distortion that leaves the victim questioning their sanity, suffering clinical anxiety or depression, or unable to function is the kind of record that supports the claim.
A successful case can recover compensation for therapy costs, lost wages, medical treatment, and emotional suffering itself. Where the defendant’s conduct was particularly malicious, punitive damages may also be available, though states vary significantly on whether and how much they cap. Filing deadlines for emotional distress claims generally run one to three years from the last abusive act. Miss that window and the claim is gone regardless of the evidence.
Gaslighting in Custody Disputes
Family court is where this evidence tends to carry the most weight, because judges in custody cases are directly tasked with evaluating each parent’s behavior and its effect on the children. Every state applies some version of a “best interest of the child” standard, and a parent who gaslights the other parent, or the children themselves, is undermining the stability that standard protects.
A parent who distorts a child’s perception of reality, denies events the child witnessed, or systematically turns a child against the other parent through manipulation is engaging in conduct courts treat as harmful to the child’s psychological development. Consequences can include reduced custody or visitation, supervised visitation requirements, or sole custody awarded to the other parent.
One caution runs the other direction. Courts are alert to false accusations raised for tactical advantage in custody fights. A parent caught making unfounded abuse claims can face sanctions, a loss of credibility with the judge, unfavorable custody changes, or even perjury charges. The same reality that protects falsely accused parents also means legitimate concerns need solid documentation before being raised in court.
Workplace Gaslighting
Gaslighting at work becomes legally actionable under federal law when it is tied to a protected characteristic. Federal law prohibits workplace harassment based on race, color, religion, sex, national origin, age (40 and older), disability, or genetic information.4U.S. Equal Employment Opportunity Commission. Harassment A supervisor who repeatedly denies an employee’s contributions, questions their competence, or distorts what happened in meetings may be creating an unlawful hostile work environment, but only when that behavior is linked to one of those categories. Gaslighting a coworker for personal reasons unconnected to a protected trait generally is not covered by federal employment law.
The conduct also has to be severe or pervasive enough that a reasonable person would consider the work environment intimidating, hostile, or abusive.4U.S. Equal Employment Opportunity Commission. Harassment Isolated slights do not meet that threshold. A sustained pattern — a manager consistently taking credit for your work, denying conversations that took place, telling you documented accomplishments never happened — begins to look different to a court when it targets you because of who you are.
Federal law separately protects employees who report harassment from retaliation. The EEOC’s guidance says it is reasonable to report perceived harassment “even if the alleged harassment has not yet risen to the level of a ‘severe or pervasive’ hostile work environment.”5U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Retaliation and Related Issues Firing, demoting, or punishing an employee for complaining violates a separate law even if the underlying harassment claim is weak. Charges go through the EEOC, and the deadline is 180 days from the last incident, extended to 300 days in states with their own anti-discrimination enforcement agency.6U.S. Equal Employment Opportunity Commission.

Proving It Happened
Every legal path above runs through the same obstacle. Gaslighting is designed to leave the victim doubting their own experience, which makes it hard to document after the fact. Building a record in real time works far better than reconstructing one later.
A journal kept as events happen is one of the most useful forms of evidence. Record what was said, when, where, and who else was present, with as much specific detail as memory allows and a note on how the incident affected you. Courts treat contemporaneous records — notes made at or near the time — as more credible than accounts assembled months later.
Text messages, emails, voicemails, and social media messages can be powerful because they timestamp what someone actually said and make it harder for the sender to later deny it. To be used in court, digital communications must be authenticated, meaning there has to be proof the person you claim sent them actually did. That can come from a known phone number, references to facts only the sender would know, or characteristic writing style. Save originals rather than screenshots when possible, and back them up in more than one place. If most communication happens in person or by phone, following up important conversations with a text summarizing what was said can be useful; the response, or the silence, becomes part of the record.
In cases involving sustained manipulation, a mental health professional can testify as an expert witness about the patterns of abuse and their effects. Under the Federal Rules of Evidence, an expert has to be qualified by knowledge, skill, experience, training, or education, and the testimony has to rest on sufficient facts, reliable methods, and a sound application of those methods.7National Institute of Justice. Rules for Experts FREs 701-706 A psychologist or psychiatrist who has evaluated the victim and can explain how the documented behavior fits recognized patterns of coercive control is often what separates a claim that sounds subjective from one a court takes seriously.
