The Professional Support Lawyer (PSL) provides a central resource for research within a given practice area. PSLs tend to operate in large law firms and support the wider division through provision of key cases, legislation and practical working knowledge, allowing fee-earning solicitors to focus on chargeable work. The PSL is usually a senior position and the role often involves overseeing support functions such as IT. In general, Professional Support Lawyers have no less than 3 years post qualification experience as well as good academic backgrounds. PSLs are mostly found in large City firms, but smaller specialist groups such as insolvency, tax, IP/IT, employment and construction also employ PSLs.
