UK firm Dickinson Dees is laying off 90 staff out of a total of 775, a number which includes 15 fee-earning solicitors.
Every office except London will be affected, with property divisions taking the brunt of the cuts.
Senior partner Robin Bloom expects turnover for the current financial year to be maintained at around last year’s £50 million ($71 million).
Dickinson Dees currently employs 773 people across its five offices in Newcastle, Tees Valley, York and London..
