The Law Society of England and Wales is to launch an investigation into the number of in-house lawyers currently working without practising certificates as concern mounts among corporate counsel over the escalating cost of practising certificates and the professional privilege rights of those without them.

Commerce & Industry (C&I) Group chair Carol Williams met with Law Society president Peter Williamson earlier this month to discuss the rising burden of paying for the practising certificate, the cost of which has risen from £460 to £910 over the past five years – an increase of more than 65%.
