DLA Piper's Singapore corporate head Sheela Moorthy has left the firm to join Norton Rose Fulbright, making this the fourth partner exit from the base since mid-2012.

DLA now has just four partners permanently on the ground in the city-state, namely India specialist Biswajit Chatterjee, ex-Norton Rose restructuring partner Troy Doyle, ex-Shearman arbitrator Yu-Jin Tay, as well as insurance specialist and Singapore managing partner John Goulios.

Moorthy's departure follows those of IT partner and former office head Matt Glynn in August, finance partner and also previous managing partner in Singapore Martin David in May who joined Ince & Co, and disputes partner Justyn Jagger, who left the firm to join local outfit Stamford Law some months earlier.

DLA declined to comment on the recent exits, but has previously acknowledged making some changes to its Asia practice.

These include the creation of a new US-led management committee for the region in December, the appointment of Cushman & Wakefield to conduct a real estate review for its offices in Shanghai, Hong Kong and Singapore, and some earlier consolidation of its groups in Hong Kong and Australia.

In a recent effort to bolster the Singapore base, the firm has required ex-Mayer Brown Hong Kong finance partner Ben Sandstad to now split his time between Hong Kong and the city-state, as well as hiring O'Melveny & Myers partner Timothy Tan in Bangkok.

Moorthy's move to Norton Rose meanwhile comes some nine months after two key dealmakers Jake Robson and Adam Summerly left the firm to join Morrison & Foerster (MoFo).

She has more than two decades of experience working on cross border M&A in South East Asia, and joins the firm shortly after it announced the renewal of its Qualifying Foreign Law Practice (QFLP) or local licence for a further five years.
