Solicitors conducting investment business could face a double- whammy of regulatory costs when the Financial Services Authority (FSA) begins monitoring law firms, investment experts have warned.

Firms undertaking investment business have until 25 September to respond to a consultation paper published on 30 June, which suggests how the FSA will charge the firms. But there is no discussion of how much firms will be charged – an omission that is causing the Association of Solicitor Investment Managers (Asim) concern.
