The paperwork jungle: 7 documents you need to sell a German property

Why documents matter more than you think

German property sales are notarial transactions. The Kaufvertrag is drafted by the notary, and before a draft can be prepared, every document on this list needs to be in the notary's inbox. Missing a single item can delay the notary appointment by three to six weeks — often enough for a buyer who has been pre-approved by their bank to lose their rate lock.

Start gathering these documents the moment you decide to sell, not after you accept an offer.

1. Grundbuchauszug (Land registry extract)

Where to get it: Your local Grundbuchamt (land registry). In Berlin, this is handled online via the Grundbuchamt portal or in person at your district court (Amtsgericht).

Cost: €10–€20 per extract.

Time: 3–5 working days online; can be same-day in person at quieter offices.

Validity: Courts accept an extract up to 3 months old. Order it fresh when you're close to accepting an offer.

The extract shows who owns the property, any registered charges (mortgages, easements, rights of way), and the official plot number. If there is an outstanding mortgage, you'll need a confirmation from your bank (Löschungsbewilligung) to prove the lien can be cleared at closing.

2. Wohnflächenberechnung (Living area calculation)

Where to get it: From your original purchase documents, the WEG (homeowners' association) records, or — if neither is available — a licensed architect or surveyor can prepare one.

Cost: Free from documents; €150–€400 if a new calculation is needed.

Time: 1–2 weeks if a professional calculation is commissioned.

Validity: No formal expiry, but buyers and their banks may query a calculation older than 10 years if the flat has been modified.

The Wohnflächenberechnung is the official basis for the price per square metre quoted in your listing. Discrepancies between the WFL document and your listing figure are a common source of price renegotiation — get this number right from the start.
