Sometimes a German customer refuses to accept a building job and names defects. Section 650g of the Civil Code then gives the builder a right. The customer must take part in a joint record of the work’s condition. The record should be dated und ist von beiden Vertragsparteien zu unterschreiben, and must be signed by both parties. If the customer stays away, the builder may make the record alone. Once the work is handed over, an obvious defect missing from the record is presumed to have arisen afterwards and to be the customer’s responsibility.
