The series contains invitations from consuls (civil law judges) which, at the request of the plaintiff, were addressed to persons (defendants) outside the Dubrovnik Republic. These persons were asked to come to Dubrovnik for a court hearing or a court discussion within a certain period, usually 2 or 3 months. The registers of this series date the 30s of the 15th centuries, and from the period from the beginning of the 17th century till the beginning of the 19th century.

The series contains a small number of records concerning Jews, and the data in the series are relevant for the analysis of the Jewish business network in the Balkans and in the Mediterranean. Some members of Dubrovnik Jewish families are referenced to in the series, as well as some members of Jewish families living in Italian (Ancona) and Ottoman cities (Sofia, Sarajevo). The records show references to the following families: Abeatar, Azubi, Barnathan, Benvenisti, Campos, Coen, Maestro, Oef, Pappo, Pardo, Usiel. For example, in April 1652, at the request of David Maestro, who was Solomon Oef's attorney, the consuls invited Achiva Barnathan from Sofia to come to Dubrovnik within two months' time or to send his representative. He was charged with a debt to the deceased Abraham Oef (vol. 4, ff. 56v, 57).
