Clear Aims & Objectives
A proposal should clearly outline the aims and objectives of the coming dissertation. What are the questions you're going to work towards answering throughout the dissertation, and what do you hope to achieve in doing so? The best way to lay this out is by including research questions, which will help to shape your overall discussion.
Clearly Defined Chapters
Law dissertations differ from other subjects in that they are almost always entirely literature-based. Because of this, they don't have a “traditional” structure, which makes the structure of a Law dissertation very different from other disciplines. The proposal is, therefore, the perfect time to outline your plan – propose the entire structure of the dissertation, breaking down the topics and points which will be discussed in each chapter. This helps to solidify your ideas and develop a cohesive, over-arching argument which will run through the whole piece of work.
