About Us


The CLLS and its specialist committees convene and convey the views of the sector, and provide advice to regulators, the Government, lawmakers, and other stakeholders. Such views are typically conveyed by the CLLS through consultations on new policies or sectoral reforms, original research, topical commentary, and participation in forums or debates.

At a time of significant evolution for the legal sector, not least in the context of recent debates around the importance of the Rule of Law, it is vital that the UK maintains its international reputation as a jurisdiction of choice for business.

All members of the CLLS play a critical role in driving the UK economy, a position that City law is determined to maintain in the face of challenging economic headwinds.

Main Committee

The CLLS Committee (also known informally as the ‘Main Committee’) is our governing body, guiding and directing the work of the City of London Law Society. The Committee meets four times a year and has up to ten elected members drawn from across our membership. Representatives from the City of London Solicitors’ Company and The Law Society Council also attend on an ex officio basis.

Committee elections are held annually with vacancies usually advertised each March. If you are interested in serving on the Committee, please contact [email protected] to find out more.


The CLLS was originally part of the City of London Solicitors’ Company (CLSC), the Livery Company for solicitors in the City of London, founded in 1908. In 1969 the CLSC established a separate Committee to deal with professional business matters; and since 1986 this has been known as the City of London Law Society.

The CLLS became an unincorporated association in 2007, making it possible for firms to join as Corporate Members, thereby acquiring for all their City-based solicitors similar benefits to individual members and confirming the position of the CLLS as the pre-eminent professional representative body for solicitors and law firms in the City.

Since then, the membership of the CLLS increased significantly. Today, we are one of the largest local Law Societies in the United Kingdom.
