The subject of international law brings a lot of concepts to mind, from war and settlement of disputes between States, protection of the environment, responsibilities and obligations, to human rights protection between citizens, refugees of different States and corporations. Globalization has forced us to interact with each other, making it essential to have common rules to guide and sustain relationships (of trade, investment, technology, etc.) between individuals and States from different regions and continents. Now, many of domestic laws are highly influenced and molded by the rules of international law. International law provides mandatory principles, norms and rules that regulate the relations between States as well as with other non-State actors, like international organizations and individuals.

Knowing how to draft a contract, understanding how to use specific vocabulary with clarity and precision, and learning to navigate legal English are all valuable transferable skills that have become more accessible for all audiences through this collaboration.

In addition, the implementation of the most up-to-date technology available to the courses has made the online learning experience as smooth and engaging as possible. 

The Legal Writing Courses include the following courses: Contract Law, Contract and Legal Document Drafting, Legal English course, and Legal Writing. Other courses will be added over the coming months.
