Property Guide · Berlin · Due Diligence
When you buy an apartment in Berlin, you receive a bundle of German documents — often hundreds of pages — and you are expected to understand them before you sign. For most Indian expats this is the most intimidating moment of the whole process. It shouldn't be. Once you know what each document is for, it becomes a checklist.
Here is what WEG documents are, which ones matter most, and the red flags worth taking seriously before you make an offer.
WEG stands for Wohnungseigentümergemeinschaft — the community of owners in an apartment building. Buy a flat in a multi-unit building and you automatically join it. You own your apartment (Sondereigentum) and a share of everything shared: the roof, façade, stairwell, heating system, garden.
The community decides things together, employs a property manager, collects a monthly Hausgeld for running costs, and can charge a Sonderumlage (special assessment) when a big bill lands. So when you buy a flat, you are also buying into the financial health of the whole building — and these documents are how you check it.
This is the legal instrument that originally divided the building into individual flats. It defines what is yours alone versus shared, sets your Miteigentumsanteil (MEA — your ownership share, e.g. 85/1000, which decides your slice of every shared cost), and contains the Gemeinschaftsordnung, the rulebook of the building.
Check that your MEA matches the Grundbuch, and read the Gemeinschaftsordnung for unusual rules — restrictions on renting the flat out, requirements to use specific materials in renovations, or a Zustimmungsvorbehalt requiring community consent to sell or rent.
German WEGs must meet at least once a year, and the minutes (Protokolle der Eigentümerversammlungen) record everything decided about the building. Ask for the last three years, and read them properly. This is where the building's real story lives.
The words to know: in the minutes, "beschlossen" means resolved and approved. "Vertagt" means deferred — discussed but not settled, and it may come back as a cost you inherit. "Abgelehnt" means voted down.
The budget forecast for the year, and the source of your monthly Hausgeld figure. Confirm the Hausgeld matches what the seller told you, and check whether an increase is already planned. Look at how much is being contributed to the reserve fund (Rücklage) each month — a very low contribution can signal an underfunded building, which makes a future Sonderumlage more likely.
What the building actually spent last year versus what was budgeted. The things that matter:
On translation: these documents are in German legal and accounting language, and standard translation tools miss the nuance of terms like Beschlussfähigkeit (quorum) or ordnungsgemäße Verwaltung (proper management). If you don't read German fluently, have them reviewed by someone who understands the WEG framework specifically — not just someone who speaks the language.
Not necessarily. A problem in the documents is a reason to ask questions and negotiate, not automatically to run. A Sonderumlage the seller has already paid is not your problem — as long as the contract clearly says so. One that's been discussed but not yet formally decided is more concerning, because it may land on you.
The rule, as always: know about it before you sign. Everything is negotiable before the notary appointment and almost nothing is after it.

Book True Price →It is not light reading. But the WEG bundle is the most honest picture of what you are really buying — not just a flat, but a share of a building and an ongoing financial commitment. An hour spent understanding it, or a professional review, is one of the best-value things you can do before committing hundreds of thousands of euros.
What are WEG documents in Germany?
WEG documents relate to the Wohnungseigentümergemeinschaft — the community of apartment owners in a building. They include the Teilungserklärung (founding document), meeting minutes, the annual budget (Wirtschaftsplan), the annual accounts (Jahresabrechnung), and the management contract. Together they show the legal and financial health of the building you are buying into.
What is a Sonderumlage and why does it matter?
A Sonderumlage is a special financial assessment the owner community charges when a major or unexpected cost arises, such as a roof or heating replacement. It matters because as a new owner you can become liable for one. Check the meeting minutes for recent or pending Sonderumlage decisions before making an offer.
Which WEG documents should I read before buying an apartment?
At minimum, read the Teilungserklärung, the last three years of owner meeting minutes, the current Wirtschaftsplan, and the last two years of annual accounts (Jahresabrechnung). These reveal your ownership share, monthly Hausgeld, the reserve fund balance, any special assessments, and any recurring building problems.
What is a healthy reserve fund for a WEG building?
There is no fixed rule, but the reserve fund (Instandhaltungsrücklage) should be proportionate to the building's age and condition. An older building with a very small reserve is a warning sign, because major component replacements can cost from tens of thousands to hundreds of thousands of euros, making a future Sonderumlage more likely.
Do I need to understand German to read WEG documents?
The documents are in German legal and accounting language, and standard translation tools miss important nuances. If you do not read German fluently, have the documents reviewed by someone who understands the WEG framework specifically, not just the language, so that risks like pending assessments or recurring defects are not missed.
