Before applying for a trademark in Spain you should check if that trademark is already registered in this country. In www.Patentes-y-Marcas.com we offer a direct link to the official Trademark Search in Spain. The use is free. However, remember that the results offered by the search engine only include identical marks, so similar trademarks to which you wish to register do not appear in the results. These similar trademarks are also an impediment to the registration of your trademark so we recommend you to hire professional services to perform a complete trademark search before applying for registration of your trademark in Spain.
If you wish to register a trademark in Spain, is also advisable to hire the services of a professional who not only does the trademark application correctly but also offers a surveillance service.
