This study is based on the analysis of Leonese legal documents from the second half of the 13th century; and it focuses on syntax related to the placing of pronominal clitics as regards to the verb. The studied phenomena will be analysed from the cartographical approach proposed by Generative Grammar trying to establish the syntactic changes that the Asturleonese language has undergone from the Middle Ages up to the present time as regards word order and Information Structure
