Illinois neighbor threatening court over car parked on our side of divided driveway

Location: Northern Illinois

We live in Illinois in military/privatized housing. Our home and the neighboring home have adjoining driveways with a visible seam or crack running down the middle. Each household uses its respective side, and we do not drive or park on the neighbor’s side.

Our Subaru is parked entirely on our side of the seam. It is sometimes parked farther back from our garage because I have a baby and it is easier to get the baby in and out, especially during bad weather. The vehicle does not cross the seam.

Our neighbor claims that our car makes it more difficult for her to maneuver into and out of her garage. However, she has been able to enter and exit her garage, and our security-camera footage shows her doing so.

This issue previously stopped but started again yesterday. On two occasions that day, she came outside and photographed our vehicle. She also spoke toward our security camera, demanded that we move the car, and said she would call the police and see us in court. Her behavior has made me worried that she may confront me when I return home alone.

We have saved the security-camera footage and taken wide photographs showing the car, driveway, and center seam. We are also contacting housing management to ask them to confirm in writing whether the seam represents the assigned boundary and whether our parking complies with housing rules.

My questions are:

1. Could she successfully sue us merely because our car makes her maneuvering less convenient, even though it is entirely on our side and she can still enter and exit?

2. Could a court order us to park farther forward, or would this primarily be an issue for housing management?

3. Does repeatedly entering our side to photograph the vehicle and demand that we move it potentially constitute trespassing or harassment after we tell her not to enter our side?

4. Besides saving the videos, photographs, and housing correspondence, is there anything else we should document?

5. If she files something, how would we be formally notified?

We do not want to escalate the situation. We only want to understand our rights, remain compliant with housing rules, and avoid being confronted.
