The LSA is a not-for-profit company.

We have a Board of Directors, who with support from the secretariat team at Achill Legal, oversee the day to day governance and delivery of the network.

Our Executive Firm members help to set the strategy and direction of the network, ensuring we remain relevant and respond to the challenges facing the legal sector.

The Executive Firms meet three times a year for Chatham House style discussions and events. Membership of the Executive allows firms to exchange ideas and discuss issues in a non-competitive and collaborative environment. To join the Executive please contact [email protected].
