Reading the community documents before buying a flat: turning three promises into a documented scope of acquisition

When buying a flat in Germany, how do I check coherently which rooms and uses I am acquiring, which community rules apply and which costs follow from them?

The offered flat is said to include a study, a specific garden area and a favourable share of the communal costs. The statements sound consistent, but come from different sources. Your purchase decision requires a connection between the legal unit, its use and the applicable communal rules. A large collection of documents alone does not yet establish this connection.

Translate your main wishes into concrete questions to check

Our editorial recommendation: Start with the features on which your purchase decision actually rests. Which rooms do you want to use, which area do you want to maintain alone and what ongoing burden can you bear? For each statement write down who made it and which document has supported it so far.

This makes the document review focused. The sales floor plan answers a different question than a communal rule on use or a resolution on cost allocation. If two sources do not match, leave the contradiction open until the appropriate expert has resolved it.

Check the unit from the register to the inspected door

§7 WEG links the land register and plan reference with the statutory annexes. [PLAN-UND-REGISTER] Assign the actual unit and all allegedly belonging rooms to the purchase advice. Present land register documents, decisive deeds, the partition plan and supplements together.

Then compare the legally designated rooms with the actual scope observed during viewing. A room used today may raise an additional allocation question. The article does not declare any particular floor plan correct and does not confirm a living area or building law use characteristic solely from a room number.

Distinguish law, decision and payment

§5 WEG sets limits on which building parts can be separate ownership; certain parts relevant to the structure, safety or communal use remain communal. [BAUTEILE] A component within the flat must therefore not be classified solely by its location.

For any planned work note three separate questions: What legal allocation exists, who decides and who bears the costs? That you are willing to pay does not automatically answer the other prerequisites. Exclusive use of an area is not treated as permission for any desired installation without examination.

Determine the applicable status instead of only the oldest deed

Consider the original communal rules together with relevant amendments and resolutions. §10 para. 3 distinguishes, for the effect against subsequent acquirers, between the agreements referred to there or resolutions based on them and other resolutions. [NACHFOLGE] The two blanket statements “everything must be in the land register” and “any private house agreement automatically applies to buyers” are therefore of no help.

For a point decisive for you ask for the concrete basis and its evidential status. An announced change of resolution and a resolution already in place are different pieces of information. Ongoing disputes belong, together with the actually available documents, in the legal review.

Place the cost assumption next to its current key

§16 governs the statutory cost allocation and allows deviating resolutions to the extent specified. [KOSTENREGEL] Therefore do not automatically scale a claimed communal expense down by your ownership quota. Ask for the concrete allocation of cost type, basis and prescribed share.

For purchase comparison list confirmed ongoing amounts and known additional measures separately. A low current service charge does not answer every future building question. How a payment between the seller, buyer and the community is to be treated must be clarified on the basis of the actual transaction.

Hypothetical case: Three matching statements still do not fit together

A buyer wants to use a designated room professionally and alter the adjacent garden area. He also plans on a stated low cost share. The selling side refers to the declaration of division for all points in general terms.

The buyer now assigns each wish to its actually relevant basis. Use, planned intervention and costs are examined separately and then brought together again in a purchase decision. The example confirms neither a prohibition of use nor an additional payment. It shows why a collective answer does not resolve the different questions.

Match the result with the purchase contract

Finally clarify whether a transfer consent pursuant to §12 is envisaged for the specific acquisition and which declaration is needed in the procedure. [KAUFZUSTIMMUNG]

Before committing it should be apparent which decisive features are evidenced, which promise must be correctly recorded in the contract and which point remains open. A handover protocol later does not replace a legal allocation that is unresolved today.
