Juliane Pethke was born and went to school in Dresden. Following a one-year sojourn in France, she studied Law in Greifswald. She then passed her clerkship at the district courts (Landgerichte) of Verden and Hannover in Lower Saxony. During her clerkship, she worked at a medium-sized law firm focusing on commercial and corporate law, among others.

In the course of both her studies and her clerkship, she again spent several months in France in order to get to know the country and its people and familiarise herself with the French judicial system.

In October 2016, she returned home and joined the contract awarding law team at Battke Grünberg.

Miss Pethke speaks English and French.
