The question is asking for legal experience specifically so if you do not have much work experience, you will have to use other experience and explain how you plan to apply it to this position. Or perhaps you have a story of what inspired you to move into the legal field that would help clarify your desire to work in the position.

"I decided I wanted to work as a paralegal during my undergraduate studies. After getting my bachelor's degree, I took night classes for my paralegal certification. I made sure to network with those instructors so I could better learn what is expected from a paralegal. I also worked as a research assistant for one of my instructors, which helped with my legal research and writing skills. While I have not worked in a paralegal position before, I am confident that I bring skills to the position that will help me succeed in this role."
