In order to avoid legal disputes between the crafts enterprise and the customer (consumer pursuant to Section 13 of the German Civil Code), the chambers of crafts have arbitration boards. These mediate in disputes arising from contracts for work and services between the owner of a craft enterprise and the client. The arbitration boards of the Chambers of Skilled Crafts and Small Businesses can be called upon by both clients (consumers pursuant to Section 13 of the German Civil Code) and skilled crafts businesses!
