Ramesh K. Vaidyanathan

Managing Partner




Ramesh Kalpathy Vaidyanathan is the Co-Managing Partner of BTG Advaya. He is a general corporate lawyer with varied experience in M&A, joint ventures, projects and infrastructure and aviation. 

Before co- founding BTG Advaya, Ramesh was the Founder and Managing Partner of Advaya Legal, a full-service law firm in Mumbai that he set up in 2010.  

Starting his legal career in Delhi in 1997 as a junior associate with a large Indian law firm, Ramesh moved to Mumbai in 2001 to set up the law firm’s Mumbai office. He was the Resident Partner of the Mumbai office of the firm until 2006. During this period, Ramesh helped set up several international companies in India that involved advice on company formation, joint venture documentation, M&A transactions, regulatory approvals, lease of premises and employment agreements.

When India's busiest airports in Delhi and Mumbai were privatised in 2006 in an unprecedented PPP initiative of the Government of India, Ramesh moved in-house as the General Counsel of the Mumbai International Airport development and modernisation project. Given the complexities involved in developing India’s busiest yet completely land constrained airport in the heart of Mumbai, the project was rated by many experts as one of the most challenging infrastructure projects in the world. In addition to this airport role, Ramesh was also the GVK Group counsel, advising on power, retail, oil & gas, hotel, mining, port, road and other infrastructure projects. He continued in that in-house role until 2010. 

Ramesh is active in legal fora at the national and international level and speaks regularly at various conferences.  Ramesh has taught Indian law course modules at the Michigan State University (MSU) in the US and has also rendered a visiting lecture at the Seikei Law School in Tokyo. He is also the founder director of Advaya Charitable Foundation that works with organisations creating awareness for legal education among underprivileged sections of society and in supporting them to access quality legal education.
