Legal Writing Courses


The British Legal Centre and UNITAR have created a system where both organizations’ audiences may be introduced to further opportunities to advance their skills, networks, and careers on their own time. Having an understanding of the legal system and being able to navigate it in an informed manner is essential even for those who have not undertaken a profession involving the law. 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.  

As the current health crisis has caused many to work from home and have an increasingly irregular schedule, all our courses are set up to be as flexible as possible.  Lessons can be accessed through private one-on-one courses, group lessons, or pre-recorded lessons which can be accessed any time. All courses are set up to use a hands-on approach where students apply the theories they have studied to real-life situations, through case studies, interactive exercises, and more. 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.


The Contract Law course covers the law of contract and the vocabulary needed by lawyers working in this area of law. The course uses video-conference technology to deliver brief online speaking, reading, and listening exercises and tasks. The exercises following each lesson include a variety of different multiple-choice tasks. These are designed to help participants understand and learn the correct use of the vocabulary through its use in simulated work scenarios that occur in the daily working lives of lawyers in practice. This course includes the legal principles of contract law and deals with breaches, remedies, estoppel, part-performance, restraint of trade, guarantees, indemnities, warranties, conditions, and other essential contract law.
