After accepting the terms of the preliminary contract, the parties enter into a final sales contract in the presence of a notary. Before signing the contract, the notary must read through the text of the contract out loud and distinctly in German. If one of the participants in the transaction is a foreigner, the text of the contract must be translated for him by an interpreter. The document, signed by the buyer and seller, is certified by a notary.

The presence of the buyer on the transaction is optional. His interests can be represented by any authorized person with a power of attorney issued by a notary.

After the conclusion of the transaction, participants receive notarized copies of the contract of sale. The original remains in the archives of the notary.
