I would say yes, the person probably has mental issues. Get him/her some help.
Another View: What is described in the question does not fit the legal definition of "stalking." The person may be a nuisance, or a 'nosy neighbor' - OR - just possibly your property NEEDS watching and reporting.
No, assuming that it is, in fact, a shared driveway (see your deeds), neither neighbor has the right to obstruct the right of way. You can only park within your property lines; you cannot park so as to lie within the other neighbor's property. I had the same issue with my property, but later found out the driveway wasn't actually shared (it belonged to me!).
Yes, if you are blocking your neighbor's free access or causing any inconvenience. Even if you own the property you own it subject to your neighbor's right to use it. Neither one of you can park on the driveway so as to block the other party.
I would think not, if your driveway is private property. Take pictures of the car and complain to the police.
If its on his property line and there is no easement then the only thing you can do about it is flip him the bird when he drives by.
it might be wise to order a 'survey' to determine exactly where the property lines are and determine if there are any encroachments by you or your neighbor. surveys cost roughly $250 - $300.
draw a line on the driveway that equally separates the two sides
Pedestrians have the right of way. Unless you can prove he/she was grosely negligent or did it on purpose then you are at fault. If you are backing down on your private driveway and a neighbor who walks behind your car on your private driveway is hit and falls down who is at fault? The neighbor pedestrian has been drinking, unstable on his feet was standing in his driveway at his car then suddenly is behind my vehicle.
An encroachment is an infringement on someone else's rights or intrusion on another person's property. It is most often used when describing real property such as the corner of an neighbor's garage that extends over the property line or a driveway that gradually grew over the property line and is now partly on your neighbor's land. Encroachments are often caused by surveyor error in placing the pins marking the boundaries in a subdivision and the party who built their swimming pool partly on their neighbor's land was not at fault.
You should address the situation immediately. You should consult an attorney who specializes in real estate law in your area. She/he can review your deed and your neighbor's, and also any recorded survey of the properties. You should take copies of the deeds and any surveys with you to the first meeting. After reviewing all the pertinent records the attorney will be able to determine what your options are. You may have the right to demand that the neighbor move their driveway off your property depending on how long the encroachment has been in existence. You may find the neighbor has an easement or has acquired some rights if the driveway has been in the same location for many years. It is better to get a legal opinion before trying to discuss it with the neighbor. If the encroachment isn't too serious you may simply give your neighbor written permission for the encroachment, signed in duplicate by both parties, to prevent them from acquiring any rights in your property.
In the UK it can, if the driveway is private property.
If the driveway is on private property then in most states it is considered private property. Though laws differ still per state on this.
In the driveway, yes because it is your own property. In the street, no because it is the government's property.
