DLA Piper is drawing up plans to launch an office in Bucharest to complete its Central and Eastern Europe (CEE) practice with a Romanian opening.
This year alone the firm has opened up in Warsaw, Poland's capital, and Bulgarian capital Sofia, taking advantage of a high level of economic activity in the region.
CEE regional managing partner Ivo Deskovic said: "There's one more place on the list and that's Bucharest. Romania's quite a promising country, with a potential for larger economic growth than even Poland.
"What we'll actually do in Bucharest I don't quite know yet. We're working on a number of options."
The firm currently has 160 lawyers in the region, but plans to expand further. Deskovic added that he wanted to double the number of lawyers in the Warsaw office within a few years to more than 30.
