Can you revoke any permission you give?
Yes, you can revoke the permission by, again, giving notice that the person is no longer allowed to continue with the use and then requiring them to stop the use. It may be that you'll say, “Use is revoked.” Close the gate. Put up a fence. Do something like that if it's a prescriptive easement that somebody's using to come across your property. Say it's a situation where, for example, the neighbour has put part of their driveway on your property; maybe they've put up a little entry-gate keypad on your property (and I've had this specific example), and you tell them, “I'm now revoking the consent I gave you,” and they refuse. Now, you're going to need to go to court and get an order for them to remove whatever they've put on your property. This is not a case where you can use self-help. It doesn't matter if it's a fence or something else like that; you cannot use self-help. Let's say your neighbour puts up a fence, he put it up in the wrong place, and he put it on your property. If he refuses to take it down, you should go to court and get an order that requires him to take it down. If you go take it down yourself, even though he was in the wrong, he may have a claim that he can take to court against you for removing his fence. In general, the law does not allow self-help. The only case where you can use self-help is if somebody has their tree branches hanging over your property; then you can trim them back to the property line as long as long as you do it in a reasonable manner without destroying their tree. Other than that example, don't use self-help.
