Hedge: When is it located on the boundary?

Hello everyone,

I have a question regarding fencing or boundary planting of hedges: When is a hedge actually ON (not next to) the boundary? In Hesse, at least the values for distances always refer to the distance from the boundary line to the center of the trunk – which is quite clear to me. How does this work with a hedge planted on the boundary? Is there a range within which the trunk centers must lie? After all, planting is rarely done to the exact centimeter.

Specifically, I am referring to a planting where the trunks lie about 10 cm on our property and the planned driveway is overgrown or ultimately obstructed. I would like to remove this and replace it with a base and fence. Apart from the morally correct approach, I am interested in whether I need to involve the neighbor from a legal perspective or if I can decide this on my own. If you take it down to the exact centimeter, the hedge is on my property.

Thank you in advance for your answers.

Just cut off the branches that are on your property and bother you rigorously. Set your base and that's it. Especially since, as you say, it is also still on your property.

Thank you for the reply, but unfortunately that doesn't really help me, as the trunks would still be in the way and I don't want a brown, bare Thuja hedge on my side.

I just read in the vastness of the internet: "Even if only part of the trunks of a 3 m high Thuja hedge of the neighbor is cut through by the property boundary, it is considered a boundary installation." So, as long as the boundary does not go through the trunk, it would not be a hedge lying on the boundary?

Talked to the neighbor once in a while??

No, that's not what this is about. Please see my partial sentence regarding the content focus of the answers.
