How to File Harassment Charges in Illinois: Evidence and Penalties

To file harassment charges in Illinois, you report the conduct to your local police with whatever evidence you have preserved, and the State’s Attorney decides whether to bring formal charges. Private citizens cannot file criminal charges directly. What you can do on your own, and often should do in parallel, is petition the court for a protective order, file a workplace complaint with the Illinois Department of Human Rights, or bring a civil lawsuit for damages.

Match the Conduct to the Right Illinois Statute

Illinois has no single harassment law. Several statutes cover specific behaviors, and which one applies changes the evidence you need and the penalties the person faces.

If the harassment is happening by phone, the statute is 720 ILCS 5/26.5-2. It covers using a phone to threaten, abuse, or harass someone; repeated calls made with intent to harass; calls made solely to say obscene or indecent things; and repeatedly making a phone ring to harass the person at the other end.1Illinois General Assembly. Illinois Compiled Statutes 720 ILCS 5/26.5-2 – Harassment by Telephone

If the harassment moves through email, text, social media, instant messages, or voicemail, the statute is cyberstalking, 720 ILCS 5/12-7.5. It applies to a course of conduct through electronic communication directed at a specific person, when the sender knew or should have known it would cause a reasonable person to fear for their safety or suffer emotional distress.2Illinois General Assembly. Illinois Code 720 ILCS 5/12-7.5 – Cyberstalking

Stalking under 720 ILCS 5/12-7.3 covers a broader pattern beyond electronic contact: following, surveilling, or threatening a specific person on at least two occasions, under the same “reasonable person” fear or distress standard.3Illinois General Assembly. Illinois Code 720 ILCS 5/12-7.3 – Stalking

Conduct that doesn’t fit those but is disturbing and public may fall under disorderly conduct, 720 ILCS 5/26-1, which reaches unreasonable behavior that alarms another person and provokes a breach of the peace.4Illinois General Assembly. Illinois Compiled Statutes 720 ILCS 5/26-1 – Disorderly Conduct If it crosses into placing you in reasonable apprehension of being physically struck, it becomes assault under 720 ILCS 5/12-1, a Class C misdemeanor.5Illinois General Assembly. Illinois Code 720 ILCS 5/12-1 – Assault

The distinction matters. A pattern of threatening texts could be charged as telephone harassment or as cyberstalking, and the difference is misdemeanor versus felony. Prosecutors typically weigh severity, duration, and whether you feared for your physical safety when choosing.

Report to the Police and Provide Everything

Go to your local police department to file a report. Bring your evidence with you rather than promising to send it later: screenshots, your incident log, witness names and contact information, and any medical records.

Be specific about dates, times, and what was said or done. The officer will take a report and may open an investigation, which can include interviewing the accused and any witnesses. Ask for the police report number before you leave. You will need it if you later petition for a protective order or check back on the case.

What the State’s Attorney Does Next

After police finish investigating, the case goes to the State’s Attorney’s office. The prosecutor decides whether the evidence supports formal charges, weighing how strong it is, how serious the conduct was, whether the elements of a specific statute are met, and whether the case can be proven beyond a reasonable doubt.

Not every report becomes a case. A decision to decline does not mean your experience wasn’t real. It means the criminal evidentiary bar was not met, and your other options remain open. If charges are filed, the defendant is arraigned and enters a plea, and you may be called to testify. Victim advocates through the State’s Attorney’s office can walk you through what to expect.

Evidence That Actually Moves a Harassment Case Forward

Harassment cases turn on what you can prove. Start preserving material the moment the behavior begins, not once you decide to report it.

Screenshot every text, email, voicemail transcript, direct message, and social media post. Don’t rely on messages staying in your inbox. Accounts get deleted and platforms remove content. For social media, courts want more than a printout showing a name on a post: they want circumstantial proof the person actually controlled the account, which can include personal photos, an IP address, or an email address tied to that person.

Keep a written log as things happen. Record the date, time, location, what was said or done, and anyone who witnessed it. A contemporaneous log carries far more weight than a summary written weeks later. If someone else saw or heard the harassment, ask them to write down their account while the details are fresh. Coworkers, neighbors, and friends who observed the behavior can corroborate you.

If there is any physical contact or threat of violence, photograph any injuries right away and get medical attention. Medical records that document injuries consistent with your account are strong evidence, even when the injuries look minor.

Penalties the Person Could Face

Which statute the prosecutor charges under determines the exposure.

The gap between a Class B misdemeanor and a Class 4 felony is large, which is why the same set of threatening messages can produce very different outcomes depending on how the case is charged.

File a Protective Order on Your Own

You do not have to wait for criminal charges. Illinois has three protective orders, and which one fits depends on your relationship with the person and what they did.

Order of Protection

An Order of Protection under the Illinois Domestic Violence Act (750 ILCS 60) applies when the person is a family member, household member, spouse, or dating partner. The court can prohibit further harassment, intimidation, physical abuse, or stalking, grant exclusive possession of a shared residence, order the respondent to stay away from your home and workplace, and address temporary child custody.8Illinois General Assembly. Illinois Code 750 ILCS 60/214 – Order of Protection Visible physical injuries are not required.

Stalking No Contact Order

If there is no domestic relationship, a Stalking No Contact Order under 740 ILCS 21 is the right tool. Any stalking victim can petition, and a petition can be brought on behalf of a child, elderly person, or person with a disability.9Illinois Attorney General. Orders of Protection The Illinois courts publish simplified forms so you can file without an attorney.10State of Illinois Office of the Illinois Courts. Civil No Contact and Stalking No Contact Order Forms

Civil No Contact Order

A Civil No Contact Order under 740 ILCS 22 is for victims of non-consensual sexual conduct or sexual penetration. No prior relationship with the offender is required, and the order is available whether or not there is a criminal prosecution.9Illinois Attorney General. Orders of Protection

Any of the three can be issued on an emergency basis, often the same day you file, without the other person present. A plenary order follows a full hearing where both sides present evidence, and can last up to two years for Orders of Protection.

Workplace Harassment Goes Through IDHR, Not the Police

If the harassment is at work and connected to a protected characteristic such as sex, race, religion, or disability, the criminal statutes are not your main tool. The Illinois Human Rights Act prohibits sexual harassment in employment and holds employers responsible for supervisor conduct, and also for harassment by co-workers or non-employees when the employer knew and failed to correct it.11University of Illinois. Illinois Code 775 ILCS 5/2-102 – Civil Rights Violations

You file a charge of discrimination with the Illinois Department of Human Rights within two years of the last discriminatory act, or one year for fair housing cases.12Illinois Department of Human Rights. Filing a Charge The process moves through intake, mediation, investigation, and findings, and can proceed to a hearing before the Illinois Human Rights Commission if the Department finds substantial evidence.

You can also file with the federal Equal Employment Opportunity Commission. The deadline is generally 180 days from the last incident, or 300 days when the claim is also covered by a state anti-discrimination law, which Illinois almost always provides. For harassment charges, the EEOC will examine all incidents when investigating, even ones outside the filing window.13U.S. Equal Employment Opportunity Commission. Time Limits For Filing A Charge Filing with the EEOC is required before you can bring a federal Title VII lawsuit.

Civil Lawsuit for Damages

A civil suit is a separate track. The standard of proof is lower than in a criminal case: more likely true than not, rather than beyond a reasonable doubt. That means a civil case can succeed even when a prosecutor declines to file charges.

Damages can cover medical expenses, lost wages, relocation costs, and emotional suffering. Under the Illinois Human Rights Act, workplace harassment victims can recover for emotional distress without proving a separate physical injury, which is more favorable than typical Illinois tort law. Punitive damages may be available in cases of particularly egregious conduct.

Talking to an attorney early helps in both criminal and civil harassment matters. An attorney can identify which statutes fit the conduct, advise on preserving evidence, draft protective order petitions, and tell you whether your case belongs on the criminal, administrative, civil track, or more than one at once.
