What is the difference in Spain between a lawyer and a solicitor?

In Spain there is no difference between the two. Law graduates are given the title "Licenciados en Derecho". After graduating, it is mandatory to become a member of the bar association (Colegio de Abogados) in order to be licensed as an "abogado" to begin practising. Other professions for law graduates include procurador (barrister), notary, judge, tax inspector or land registrar, among many others. High-ranking law professionals in the public administrations are very well regarded because access exams are extremely difficult and vacancies are scarce.

How are the legal fees determined? 

Fees are not subject to any scale or recommendation set by law. They are based on a number of criteria: amount at stake, timescale, difficulty, degree of specialisation, level of experience with the type of case or even the likelihood of success.
