Neighbor is building a retaining wall on my property. What should I do?

That sounds like confirmation that such tolerance existed in the past.

The tolerance does exist, only the permission does not.

Something like that is formulated by a lawyer, no one from the forum.

That's what I'm saying.

No, but you can have it towed by a towing service and the neighbor has to bear the costs. However, I would consider whether this is necessary, for example, because otherwise you have no place to park.

But regarding properties: whatever is on it (house, garage, wall) belongs to the owner of the property and they can do whatever they want with it. I would see this more as leverage to finally get a reaction from the neighbor.

I consider it a rumor that he will pay for it

Hello everyone,
thanks for your numerous opinions.
Just beforehand: I’m not the type to go to a lawyer immediately. I have an acquaintance who works at a law firm. However, I believe that is the last method. Maybe I’m just too easy?
So far, I have only needed support from my acquaintance once because someone wanted to sue me. (I won at that time).
And to your questions:
- my neighbor works in the automotive industry, not in a leadership position, has 5 children (maybe that’s why). He built a house 10 years ago and now this is his second house
- the plot is in the Heilbronn area. I got it through a lottery (300 applicants for 30 plots for 450€/m2). A private owner sold his plot for 800€/m2. That’s why I mentioned the number 800. But now I don’t care anymore, I don’t want to sell but want to get my property back.
Yesterday I spoke with the construction supervisor and asked him to speak with the neighbor/his site manager. The construction supervisor knows the site manager very well (which is bad for me). He talked to the site manager. The site manager wanted to get back after consulting with his client.
Now I’m curious how long it will take and if it will help.
I will keep you updated. Have a nice evening

A lawyer should always be the very last resort if possible, because from that point on everything is poisoned or going back becomes difficult. I think it's good if you try to resolve it otherwise first, as long as you are not really in a hurry regarding that (even if it is of course annoying).

It is your decision, and trying to resolve things without a lawyer is certainly initially correct and also commendable. Nevertheless, I would avoid these game-of-telephone antics (builder talks to site manager (?) talks to another site manager talks to another builder) and speak clearly and directly with the soon-to-be neighbor and document it in writing at the same time, because he is the factually and legally responsible contact person for this, even if he perhaps has not yet understood this himself – by the way, soon, so that no more facts are created that might eventually make a dismantling seem disproportionate.

Best regards

I did that first of all. He didn't understand or didn't want to understand. Maybe now with the construction controller it will help somewhat.
