If someone repeatedly enters your property and you don’t want them there, you have legal rights in Illinois to prevent them from doing so. Whether it’s your home, business, or land, here are the simple steps to keep people off your property.
Know Your Rights
If you own the property, you get to decide who can be there and who can’t. You can tell someone to leave and not come back. This is true for houses, businesses, and even empty land.
Tell the Person to Stay Away
First, tell the person to stay off your property. You can do this in person or in writing. Writing it down is good in case you need proof later. Be clear that they are not welcome and should not return.
Post “No Trespassing” Signs
It’s a good idea to post “No Trespassing” signs around your property. Although not required by law, signs indicate to others that they are not allowed to enter. Make sure the signs are visible.

Keep Records
Write down each time the person comes onto your property after you’ve told them not to—date, time, and what happened. If you have pictures or videos, keep those too. This will be helpful if you need to attend court.
Ask the Police for Help
If the person continues to return, you can request that the police issue a trespass warning. This means the police will officially instruct the person not to return. If they return after that, they could be arrested.
Get a Restraining Order
If the person continues to trespass and makes you feel unsafe, you can go to court and request a temporary restraining order (TRO). This is a court order that prohibits them from coming near you or your property.
How to Get a TRO:
- Visit your local courthouse and complete a form.
- Show the judge why you need the order. Bring your notes and any evidence.
- If the judge gives you the order, the police can enforce it.
Sue for Trespassing
If nothing else works, you can file a lawsuit against the person in civil court for trespassing. A judge may order them to stay away or even make them pay you money.
Call a Lawyer
If you’re not sure what to do, it’s good to talk to a lawyer who knows property law. They can inform you of your rights and advise you on the next steps to take.
