J Sagar Associates (JSA) has promoted Manvinder Singh, Trisheet Chatterjee and Poonam Verma to its equity partnership, reported Bar & Bench, while partner Akshay Nagpal has joined Indigo as associate general counsel (GC).

Correction: The earlier version of the story stated incorrectly that Nagpal would join Indigo as an assistant GC.

Gurgaon-based corporate commercial Manvinder Singh and Trisheet Chatterjee had been promoted to retained partner in 2011, while regulatory, disputes and projects lawyer Poonam Verma was elevated in 2013.

JSA co-managing partner Dina Wadia has confirmed the news.

JSA partner Somasekhar Sundaresan had announced last month that he would leave the firm, following a team of 18 headed by partner Akshay Chudasama having defected to Shardul Amarchand Mangaldas in 2015.
