The offer does not concern the entire condominium but a half minimum share. The other half is to remain with another person. Before you compare the price with an ordinary small flat, you must understand with whom you would share which legal position and use.

Do not translate the share into a specific room

§13 WEG 2002 deals with the co-ownership partnership with connected half minimum shares. The provision regulates, among other things, the other partner's consent to the transfer of the share as well as the joint disposal of the condominium and its use. [PARTNERANTEIL]

The purchase of such a share is therefore not already the acquisition of a freely available spatial half of the flat. Have the current land register status and the relevant agreements explained in full. This text does not deal with an execution nor the acquisition of a simple share in a building without condominium ownership.

Discuss the future partnership status openly

Our editorial recommendation: Describe how the flat is to be used in future. Do you want to move in yourself, rent it out together or initially only participate as capital? What expectations does the other person, who is to remain in the structure, have?

Present these intentions to the contractual advice. Have clarified which consent and arrangements are required for the planned entry and how the joint use should be regulated on a sustainable basis. A private allocation of rooms does not replace this examination.

Hypothetical case: The half price is understood as its own small flat

An interested party wishes to buy an offered share and use only one room herself. She assumes the other half simply concerns the remainder of the rooms. Such a use has not yet been agreed with the remaining co-owner.

She therefore has the share purchase, the joint legal position and her housing wish examined together. Only afterwards can she assess whether the offer suits her. The example does not promise a forced spatial division or any specific right of residence.

Also consolidate the financial relationships

Ask about existing encumbrances and the obligations relevant to the joint condominium ownership. §13 contains a special liability framework for this. [PARTNERANTEIL] What consequences arise for you must be explained on the basis of the concrete situation and contracts.

Do not compare only your offered amount and the assumed half of ongoing bills. Clarify with the bank which legal position and security are actually to be acquired or established. A financing assessment for an entire owner‑held flat is not transferable without verification.

Examine the possibility of later change before entry

Discuss with the adviser what consequences a different use, a desired sale or a disagreement in the intended structure would have. The article does not provide a termination agreement and does not decide any right of exit. It highlights the questions that already belong to the entry.

In the end it should be clear which right you acquire from which person and with whom you would share which decisions. The offered share may be sensible after examination; its suitability, however, follows from the concrete joint legal position and not solely from a correspondingly lower purchase price.
