Wisconsin Laws on Unwanted GPS Tracking

In the era of smart technology, stalking has evolved from lurking in shadows to pinging a smartphone. Finding an unknown Apple AirTag in your purse or discovering a hardwired GPS tracker under your car is a terrifying invasion of privacy. In Wisconsin, the law provides robust protections against this digital abuse. Under Wis. Stat. § 940.315, it is a Class A misdemeanor to place a global positioning device on a vehicle owned or leased by another person without their consent. Furthermore, persistent tracking falls squarely under Wis. Stat. § 940.32, Wisconsin's severe stalking statute. The state's highest court has historically taken a strict stance against nonconsensual tracking, as seen in the landmark case State v. Sveum, 328 Wis. 2d 369 (WI Supreme Court 2010), which confirmed that surreptitious GPS tracking severely infringes on personal liberty. If you are being tracked in Green Bay, Waukesha, or Appleton, you have legal remedies.

Suspicious Ex-Spouses and Domestic Stalking

During a bitter divorce or a toxic breakup, a controlling ex-partner may try to monitor your movements to see who you are dating or where you are living. They might slip a tracker into your child's backpack during a custody exchange or stick a magnetic GPS unit inside your car's bumper. This is classic domestic abuse and stalking. Even if your ex-spouse's name is technically still on the car's title, using a tracker to terrorize you can still be the basis for a domestic abuse or harassment injunction.

Overstepping Private Investigators

Sometimes, a jealous spouse will hire a private investigator (PI) to follow you. While PIs are allowed to conduct visual surveillance in public spaces, they absolutely cannot trespass onto your private property to plant a tracking device without a court warrant. If a private investigator illegally tracks your vehicle without your consent, both the investigator and the person who hired them can be sued for invasion of privacy and face criminal charges.

Obsessive Coworkers and Stalkerware Apps

Not all trackers are physical pieces of hardware. An obsessive coworker or acquaintance might gain access to your unlocked smartphone and install 'stalkerware'-hidden applications that quietly beam your real-time GPS location and text messages back to them. This violates Wisconsin wiretapping and stalking laws, providing grounds for serious legal action.

Step-by-Step Process to Protect Yourself

If you get an alert on your phone that an unknown AirTag is traveling with you, or you physically find a tracker, you must take careful steps to protect your safety and preserve the evidence.

Step 1: Safely Locate and Preserve the Tracker

Your first instinct will be to smash the device with a hammer. Do not destroy it! The device holds serial numbers and digital fingerprints linking it to the stalker. If you feel safe doing so, take a photo of exactly where you found it, carefully remove it, and place it in a plastic bag. If it is an AirTag, take a screenshot of the tracking alert on your phone.

Step 2: Report to Law Enforcement

Take the device and your evidence directly to the police. Law enforcement agencies, often coordinating with the Wisconsin Department of Justice, Madison, can subpoena Apple or the GPS manufacturer to reveal the account information of the person who registered the device. This provides irrefutable proof of who is stalking you.

Step 3: Filing a Harassment Injunction

Once you know who is tracking you, or even if you strongly suspect an ex-partner, your attorney can file Form CV-405, Wisconsin, Circuit Court, Petition for Temporary Restraining Order and/or Petition and Motion for Injunction Hearing (Harassment). You will file this at your local courthouse, such as the Brown County Circuit Court, Green Bay or the Waukesha County Circuit Court, Waukesha. The judge can order the stalker to stay away from your home, your workplace, and cease all electronic monitoring.

What Does it Cost to Fight a Stalker?

Securing your freedom from a stalker involves some legal expenses, but the court system is designed to be accessible to victims.

Filing Fee for Harassment TROUsually waived by the court for stalking victims
Vehicle Bug Sweep (Private Security)$200 - $500
Attorney Fees (Restraining Order)$2,000 - $4,500
Civil Lawsuit against the StalkerConsultation required; often billed hourly or on contingency

Timelines for Restraining Orders

In Wisconsin, when you file a petition for a Temporary Restraining Order (TRO), a judge will usually review it on the exact same day. If granted, the TRO goes into effect the moment law enforcement serves the paperwork to the stalker. You will then have a final injunction hearing scheduled within 14 days, where the judge can make the no-contact order permanent for up to four years.

Frequently Asked Questions (FAQ)

What if the police say it is a civil matter and will not arrest them?

Unfortunately, some police departments are slow to act on digital stalking. If the police refuse to press criminal charges, you can still hire an attorney from our directory to file a civil harassment injunction, which forces the stalker to stop under threat of severe contempt charges.

Can my employer track my company car?

Yes. If your employer owns the vehicle, they generally have the legal right to install a GPS tracker to monitor fleet activity. However, they cannot legally place a tracker on your personal, private vehicle without your consent.

What if I find a tracker but don't know who put it there?

Hand the physical device over to the police immediately. The manufacturer's serial number or SIM card inside the GPS can be traced back to the buyer via a law enforcement subpoena.

Can a restraining order force them to delete my data?

Yes. A Wisconsin judge can include specific provisions in a harassment injunction ordering the stalker to delete any location history, photos, or data they unlawfully collected while tracking you.
