The land register (Grundbuch) still shows Person A. Your contracting partner B declares that they have already bought the property from A but have not had themselves entered. You are now to take over directly. That is neither resolved by the seller's mere declaration nor conclusively ruled out simply because of the different name. Decisive are the legal route to registration and complete evidence of the chain of acquisition.
Describe the actual chain first
Our editorial recommendation: Note who, following which alleged transaction, passed the property on to whom. Distinguish sellers, representatives and heirs. A representative acts for another person; that is not already a separate intermediate transfer. Therefore do not use a simplified list of names without roles.
Produce the available acquisition documents and the current land register status at the time of contract conclusion. Have missing deeds explicitly identified. A verbal summary “everything already paid” does not replace a verified legal title or the proofs required for execution.
Read the Vormann principle and the special rule together
§21 GBG 1955 sets out the principle as to against whom an entry can be made: decisive is the person recorded in the books or simultaneously entered or noted as Vormann. [VORMANN]
§22 provides for the direct entry into the books to the last transferee for several successive extrabook transfers, upon proof of his Vormänner. [KETTE] This special route is therefore not a carte blanche to skip previous acquisition transactions without checking them. The chain of entries not individually reproduced requires an appropriate evidential basis.
Have the entire alleged transfer examined by a professional
Request an understandable explanation of which deed covers which step and which further declarations or prerequisites are missing. This article does not confirm any particular chain as complete and provides no usable application for the land register.
Even a requested immediate entry does not automatically address payment processing, encumbrances, ranking or required official prerequisites. These questions must be clarified for the actual transaction. Do not omit them just because the parties want a shortened registration route.
Hypothetical case: an intermediate deed is missing
A is registered, B claims an earlier purchase from A, and C now wishes to acquire from B. B only shows C his later draft sales contract. He cannot currently sufficiently document the acquisition from A. C initially regards the reference to § 22 as a complete solution.
The contract formation instead obtains the necessary documents for the A–B transfer and examines the intended route to registration as a whole. The example does not decide on the existence of an earlier purchase contract. It shows why a statutory possibility does not replace examination of its prerequisites.
Only continue planning once a route to execution is declared
Clarify with an involved bank which actual acquisition structure exists and which proofs it requires for its own review. An offer describing an ordinary already registered seller-ownership should not be used unaltered as an accurate description.
In the end you need a comprehensible answer as to from which state your acquisition is to be registered and why the necessary transitions are evidenced. Whether direct transfer or another route is suitable in the concrete case is decided by the professional review. An asserted time saving is not by itself a legal basis for that.
