You could start with the CEPI and look at their web site.

As they themselves say, though : "Legislation and regulations are on the increase. Europe claims an ability and right to legislate on real estate matters, but also acknowledges that only Member States may define the conditions and the details of implementing access to the national markets for real estate professionals. Furthermore, half the Member States have no regulations regarding this matter or have recently deregulated the real estate professions. As a result, it is very difficult to obtain coherence between the rules of the game, which sometimes vary greatly from one country to another and this could lead to possible difficulties in the implementation of European regulations in the various EU Member States. This means that legal security is blamed, the number of disputes increases and case law becomes important."

Their web site is CEPI

I'll try and find out about reporting corruption for you...
