Separation of building land/garden land

Hello everyone,
the property we are currently purchasing (documents with the notary) is very large, about 1047m². Currently, within the scope of the statute boundary for our building area, about 644m² of land area and about 403m² of private green space are noted.
Do we have to/can we have the property officially surveyed by a surveyor and then have it divided by the land registry office, or how does that work? Is it worth it in terms of water connection costs and infiltration area?

Hello,

Do we have to/can we have the property officially surveyed by a surveyor and then divided by the land registry office or how does that work? Is it worth it in terms of water connection costs and infiltration area?

What is your intention with that or to put it more simply, what do you want to achieve?

Kind regards

I want to pay less for [Wasseranschluss] and [Schmutzwasser].

I would like to join the question. We have a plot of land in prospect with a fairly large planting area. This may not be built on. Is the water/sewer connection fee due on this planting area?

If construction is carried out on a property, it must be surveyed anyway. Such questions will inevitably be answered then. Therefore, this question does not arise. I did not understand the part about the sewage. Payment must only be made for areas connected to the sewer.
Best regards Heiner
