K Law and Linklaters have advised Reliance Industries on its Rs 22bn ($450m) joint venture with Russian petro company Sibur, which was advised by Khaitan & Co and Herbert Smith, as Legally India had reported on 28 February.

This is understood to be the first time that Reliance has instructed K Law on a corporate transactional matter, although the firm has worked with the conglomerate in other advisory areas previously.

The K Law team was led by partner Praveen Raju, assisted by corporate senior associate Sankar Narayan Swamy and intellectual property (IP) senior associate Priti Deshpande, and associates Aparnaa Bhalotia and Sharmila Nair, according to a statement from K Law.

Linklaters advised Reliance on non-Indian law aspects of the transaction.

As reported in February, Khaitan & Co corporate partner Aakash Choubey and executive director Daksha Baxi acted for Sibur on Indian Law while Herbert Smith partner Nicholas Moore acted on foreign law.

K Law opened an office in Delhi in 2010 after starting as Krishnamurthy and Co in Bangalore in 1999, growing to over 60 lawyers.

Billionaire Mukesh Ambani-owned Reliance – India’s second largest public company by turnover - has in the past most commonly instructed AZB & Partners, as well as Amarchand Mangaldas, J Sagar Associates (JSA), Khaitan & Co and others on its corporate transactions.
