In order to be able to use specific professional titles in their name, companies and organisations of freelancers in professions with licence requirements have to comply with additional statutory regulations in addition to the general requirements for starting up a company. Examples of these are:

• Architect
  The title "Architect" or a corresponding combination of words in the name of a partnership or limited liability company (GmbH) may only be used under certain conditions. In the case of partnerships, at least one member of the partnership has to be registered in the list of architects. A GmbH may only use the title in its name, if the shareholders who are archtiects have at least one quarter of the voting rights, the company only works in the field of architecture and the company is registered with the Architectural Association.
• Legal firm
  Limited liability companies, whose business purpose is to advise and represent their clients in legal matters, use the name "Legal Firm", if they are admitted as such to the Bar Association. The managing director and shareholders are exclusively lawyers. When naming the firm, they have to take into account that at least the name of one of the shareholders has to be listed alongside the title.
