Harassment by a family member, in legal terms, is a repeated course of conduct directed at you that serves no legitimate purpose and would cause a reasonable person in your situation substantial emotional distress or fear for their safety. A single bad argument, even a cruel one, usually does not meet the standard. A pattern of threats, unwanted contact, surveillance, or intimidation after you have asked the person to stop generally does.
How the Law Defines It
Federal law describes harassment as a serious act or course of conduct directed at a specific person that causes substantial emotional distress and serves no legitimate purpose.1Legal Information Institute. 18 USC 1514(d)(1) – Definitions Two phrases do most of the work in that definition.
“Course of conduct” means a series of acts, over any length of time, that show a continuity of purpose. One angry phone call is not a course of conduct. Ten calls in one night after you have said stop almost certainly is.
“No legitimate purpose” is the second filter. A parent who calls to work out a custody exchange has a real reason to contact you, even if the call is tense. That same parent calling at 2 a.m. to scream insults does not. Courts look at why the contact is happening, not only how often.
State harassment statutes follow a similar shape, though wording varies. Some focus on the harasser’s intent to alarm, annoy, or torment. Others focus on the effect on the victim. Nearly all require a pattern rather than an isolated event, and nearly all apply an objective test: would a reasonable person in your circumstances feel genuinely threatened or distressed by this conduct?
Behaviors That Typically Qualify
Judges look at the whole picture rather than checking a single box. The behaviors most commonly cited in family harassment cases include:
- Repeated unwanted phone calls, texts, voicemails, or emails, especially after you have asked the person to stop.
- Threats of violence against you, your children, or others close to you that a reasonable person would take as credible.
- Stalking and surveillance: following you, showing up uninvited at your home or workplace, tracking your location through GPS or shared accounts.
- Cyberstalking: using social media or messaging platforms to post threats, share your private information, or spread damaging claims.
- Property destruction: vandalizing your car, breaking into your home, or destroying belongings as a form of intimidation.
- Financial coercion: opening accounts or running up debt in your name, withholding access to shared finances to control you, or destroying financial records.
A single category can be enough when the conduct is severe or persistent. More often, harassers combine tactics, and the broader pattern is what carries weight in court.
Where Difficult Becomes Illegal
Not every unpleasant family interaction is a crime. Context, frequency, and purpose decide where the line falls.
A mother who calls every day to check in may be overbearing, but her calls probably have a legitimate purpose and no intent to intimidate. An ex-spouse who calls thirty times in an hour while shouting threats is on the other side of the line. The volume, the timing, and the content shift the conduct from annoying to alarming.
The same act can land on either side depending on what surrounds it. A brother posting embarrassing childhood photos online is irritating. That same brother posting your home address alongside threatening language is something else entirely. The question is whether a reasonable person would fear for their safety or suffer genuine emotional distress. You do not have to prove physical harm. Credible threats and persistent intimidation are enough.
Documenting the Pattern
Because the legal definition turns on a pattern, documentation is what makes a case. Start collecting evidence as soon as you recognize what is happening, even before you decide whether to file anything.
Screenshot every threatening text, email, and social media post. Save voicemails. If the harasser deletes their messages, your screenshots may be the only record. Back everything up to a cloud account or email address the harasser cannot reach. Photograph any property damage before you repair it, and keep threatening notes or letters.
Keep a written log of every incident. For each one, record the date, time, and location, a factual description of what happened and what was said, and the names of any witnesses. The log does two things at once: it establishes the course of conduct the law requires, and it protects your memory if months pass before a hearing. Judges notice when a petitioner can give specific dates and quotes rather than general impressions.
Protective Orders and Which Relationships Qualify
The most direct legal remedy for family harassment is a protective order. The type available to you depends on your relationship to the harasser, and most states run two parallel tracks.
Domestic violence protective orders generally cover people connected by blood, marriage, cohabitation, or a romantic relationship. Specifics vary by state, but the categories typically include current and former spouses, people who share a child, people related by blood or marriage (parents, siblings, in-laws, and sometimes extended relatives like cousins), current or former household members, and current or former dating partners. These orders are usually faster to obtain, carry no filing fee under the Violence Against Women Act, and offer broader relief.
If your relationship does not fit one of those categories, a civil harassment restraining order may still be available. These apply to anyone, including neighbors, acquaintances, or more distant relatives who fall outside the domestic violence definitions. Civil orders may carry a filing fee and move a little more slowly, but once granted they offer similar protections. A court clerk or local legal aid organization can tell you which track fits your situation.
A protective order directs the harasser to stop specific behaviors, stay a set distance from you, and avoid contact. The order’s real force is that violating it is itself a crime, which gives law enforcement a basis to act immediately rather than treating each new incident as a fresh dispute.
Criminal Charges as a Separate Track
Filing for a protective order and reporting the conduct to police are two different things, and you can do both. A criminal complaint starts with a report to your local police department or sheriff’s office. Bring your documentation. If an officer concludes a crime occurred, the case moves to the prosecutor, who decides whether to charge. You do not control that decision. Criminal harassment can carry fines, probation, or jail time depending on the severity and the state’s statute. The protective order track, by contrast, is one you file and control yourself.
When Harassment Crosses State Lines
Family harassment is not always local. If a relative uses the mail, phone, email, social media, or any electronic communication to harass you from another state, federal law applies. Under 18 U.S.C. ยง 2261A, it is a federal felony to use interstate communications in a course of conduct that places someone in reasonable fear of death or serious bodily injury, or that causes or would reasonably be expected to cause substantial emotional distress.2Office of the Law Revision Counsel. 18 USC 2261A – Stalking The statute also reaches a person who physically travels across state lines intending to harass or intimidate you, and it protects your spouse or partner, immediate family, and even pets or service animals.
If you already have a protective order and the harasser moves, federal law requires every state to honor and enforce valid protective orders issued by any other state.3Office of the Law Revision Counsel. 18 USC 2265 – Full Faith and Credit Given to Protection Orders You do not have to re-register the order in a new state for it to be enforceable, though registering it with local law enforcement can speed up response if you call for help.
Firearm Consequences of a Final Order
A final domestic violence protective order can trigger a federal firearms prohibition. Federal law bars a person subject to a qualifying order from possessing, buying, or receiving firearms or ammunition.4Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts In 2024 the Supreme Court upheld that prohibition, ruling that a person found by a court to pose a credible threat to another’s physical safety may be temporarily disarmed consistent with the Second Amendment.5Supreme Court of the United States. United States v. Rahimi, No. 22-915
The ban applies when three conditions are met: the respondent received actual notice and had a chance to participate in the hearing, the order restrains them from threatening or harassing an intimate partner or child, and the order either finds a credible threat or explicitly prohibits the use of physical force.4Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Temporary ex parte orders issued before the respondent has a hearing generally do not trigger the federal ban, though some states impose their own earlier restrictions. Violating the federal prohibition is a felony punishable by up to fifteen years in prison.5Supreme Court of the United States. United States v. Rahimi, No. 22-915 If the harasser owns firearms, raise this with the court so the order can include language requiring surrender to law enforcement or a licensed dealer.
If the Order Is Violated
Violating a protective order is itself a criminal offense in every state. If the harasser contacts you, shows up where the order forbids, or breaches any term, call the police. Keep a copy of the order on your phone so responding officers can see the terms immediately.
A first violation is typically charged as a misdemeanor carrying potential jail time, fines, and probation. Repeat violations, or violations involving threats or physical contact, are often charged as felonies with much steeper penalties. Courts can also hold a violator in contempt, which brings its own sanctions. Document each violation the same way you documented the original pattern. Every incident strengthens the record if you need to extend or modify the order, and it builds the case for prosecution.
