Hedge: When is it located on the boundary?

If the driveway is not yet built but planned, I would not start with such small stuff and risk causing trouble right from the beginning. Plan the driveway according to the conditions and that's that.

If the hedge is on your property, even if only partially, you are not allowed to simply remove it.

Please just stick to the question in my initial post. I have no need for lectures but require feedback regarding legal opinions on this matter. Since you do not know the framework of the previous neighborly relationship, I simply ask you to refrain from such advice.

That looks better already! Many thanks! After some research, the principle seems to be regarding cutting the trunk at ground level with the boundary.

Also remember that you cannot simply cut branches that extend onto your property if doing so endangers the life of the plant. There are no clear regulations in such situations that provide you with legal certainty to act without involving the neighbor.

Thank you for the note. If the hedge belongs to both of us, then I will not do that or will discuss the measure with the neighbor. If it is 100% mine, then it will be removed, because on the one hand it is anyway ailing and on the other hand does not fit the planned front yard design.
