If you are refused a Schengen visa, you are entitled to appeal against the decision. You must lodge the appeal against the Member State that refused your application. The appeal will be conducted in accordance with the national law of that Member State. The Notice of Refusal will usually provide you with information regarding the procedure to be followed in the event of an appeal including the competent authority and time limit for lodging such an appeal. There is no requirement to pay a fee for lodging an appeal against a refusal of Schengen visa.
