While looking for flats to rent I saw that someone aks for a SCHUFA. What do I need to do in that case?
It’s been a while (five years, to be exact) since I last applied for a flat. However, in my limited experience it is not you who provides the Schufa exerpt. Rather, you sign a slip giving the landlord permission to perform a Schufa lookup. The landlord then requests the details, submitting why he needs them, Schufa checks if they have a file on you and if so forwards only the information the landlord needs to know in a rather basic form.
You can also check your own Schufa record. This requires filling out a form from the respective site, printing it, adding a return envelope with your address and sufficient stamps (iirc) and then sending it by mail. They will send you a much more detailed breakdown of their data on you, including who requested a lookup when. Under no circumstances should this extensive data be forwarded to the landlord.
