In the last years higher German courts accepted argumentation related to undisclosed kickback payments having misled investors, such that compensation claims can be (partially) based on that.
Bank consultants and Brokers are thus incentivized to somehow disclose or make it possible to discover any kickback payments when working with a customer shopping for investment funds, prior buy order submission.

Relevant legislative developments are summarized in an article by the German BaFin (Federal Financial Supervisory Authority): Zuwendungen - Verbot mit Ausnahme: Verschärfte Spielregeln für Provisionen und andere Vorteile (2018, English version: Inducements - Ban with an exception: tighter rules for commissions and other benefits).
Basically, relevant laws and European directives nowadays are the Wertpapierhandelsgesetz (WpHG) and MiFID II, as of 2024. The arguably stricter regulation regarding provisions in MiFID II is effective since 2018 or so.
Hence, one way to learn whether a certain fund routes kickback payments to your broker, prior to buying any shares, is to prepare an order for - say - one share using the order mask of your favorite German online broker.
Instead of submitting the order you can look for a button that generates an ex-ante cost report, i.e. a listing of all the costs you would experience in case you really submit that order.
Such a button might be labeled 'Kosteninformation' (German).
As an example, I looked up a few open-end real-estate investment funds, using this online broker order-mask method (table as of 2024-05-31):

Alternatively, if you are in an offline setting at your bank, you can simply ask your bank consultant for the same documentation.
Of course, as always, be prepared to waste some time that way, because a bank consultant usually is primarily a sales person for your bank and thus might want to use that chance to try out all the great new sales tactics he/she recently learned about.
A few years ago, the VDH (an association of independent financial advisers) published an online database of periodic funds provisions. As of 2024, one can still find traces of it on the web - but it looks like it was decomissioned some time ago:
As of 2024, consumer protection organizations are still pushing for a complete ban of kickback payments in the consulting for financial products - because of the obvious conflict of interest.
In 2023, it seemed that the European Commission followed those arguments, but later stopped a reform in that area. (cf. German article by a regional consumer protection organization: Warum Provisionen in der Finanzberatung ein Problem sind, 2023-05-16)
