Liberal professions are those carried out:
on the basis of relevant qualifications,
on a personal basis,
under a person’s own responsibility,
in a professionally independent capacity, by providing intellectual and conceptual services in the interest of the client and the public (Directive 2005/36/EC on the recognition of professional qualifications).
Architects, lawyers, doctors, dentists, physiotherapists, chartered accountants, engineers, notaries, bailiffs, veterinarians and pharmacists all practise “liberal professions”.
