You are viewing a finished flat in an older building. The land register (Grundbuch) states “Wohnungseigentum in Vorbereitung”. The rooms are habitable, but your purchase target is a specific condominium. Therefore the transaction must also describe the route to that exact right in a way that is understandable.

Habitability does not explain the legal state of completion

The official information on the establishment of condominium ownership names the preparatory documents and agreements and makes clear: condominium ownership is only established upon registration (Verbücherung). [BEGRUENDUNG] Finished rooms, a signed draft and a usable area valuation (Nutzwertgutachten) must therefore not all receive the same status “finished” in your purchase summary.

Have explained to you what already exists and what is still outstanding. This concerns the legal route to creating the offered unit; a technical building acceptance and an administrative review of use (baurechtliche Nutzungsprüfung) are additional questions. This article does not fully cover any particular new-build or developer security arrangement.

Which assurance is noted for which person?

§ 40 WEG 2002 provides for the annotation of the promise to grant condominium ownership. It names the entitled person and the designated object. The provision also governs protection of rank for the later registration and specifies exceptions; it distinguishes this security step from the later condominium ownership. [ZUSAGE]

Our editorial recommendation: Ask the contract advisory service to explain the current entry based on the entire land register status and the relevant documents. Does the annotation already relate to the acquisition route intended for you or to another person? Does the designated unit match the flat you intend to buy? Which further rights remain relevant? A mere line with the word Zusage does not answer these questions.

Have a real end point agreed

The statement “parification is still to come” is too vague as a progress report. Ask about the further necessary steps, the parties responsible and the prerequisites. The legal advice should also assess how your performance obligations, payments and the registration owed fit together.

Do not impose your own blanket payment block and do not change the order of applications. Your contribution is to name the purchase target unambiguously and to make contradictions visible. The legal structuring requires examination of the entire transaction, including any other security provisions that may apply.

Fictitious case: The right flat, the wrong assumption

A purchaser sees an annotation in the land register in favour of an earlier interested party. She assumes this automatically protects any later buying person. In the advisory discussion the personal connection of the annotation to the planned acquisition is recognised as an open question.

The competent authority checks whether a legally appropriate transfer or another required step must be prepared. At the same time it is clarified which documents are missing for the later establishment of condominium ownership. The example does not decide a transfer; it shows why the existing security note should not be treated unexamined as your own finished title to ownership.

How to recognise a comprehensible intermediate stage

In the end you need three understandable answers: Which right are you acquiring now, what security exists for your purchase target and which verifiable step leads to the intended registration? Also have the consequences of a delay or a failure explained. If the financing or move-in plan works only with a legally unverified completion, the purchase decision must remain accordingly open.

The description “in preparation” is a reason for precise scrutiny. It is neither an automatic purchase warning nor a guarantee that only an insignificant formality is missing.
