Berwin Leighton Paisner has posted flat growth for the first six months of the 2008-09 financial year, attracting £84m in fee income over the period.
The firm's turnover stood at £84m at the same point last year following a 20 per cent rise.
A BLP spokesperson said: "Growth is essentially flat. We've seen fee income grow in real estate, litigation, tax and restructuring, with some slight reductions in corporate and finance."
He added: "Looking forward the next six months are very uncertain. However, we're confident that we're well positioned and that we'll continue to receive premium mandates for transactional and contentious work."
International contributions were deemed to be "slightly higher than expected". BLP has foreign offices in Brussels, Paris and Singapore and is due to open in Abu Dhabi in January 2009.
