Our Story

Sidney Kingsley and David Naphtali decided to start a law firm together, originally named Kingsley, Kennedy & Co. David offered civil and criminal litigation services and Sidney offered non-contentious services, in particular commercial property. After serving in the war, David and Sidney reopened the firm in 1945 as Kingsley Napley.

While we remained a small firm of less than 20 people, we began to make a name for ourselves as litigators of renown. We also started to take on licensing work, in particular for London’s celebrity restaurants and entertainment venues.

Kingsley Napley became established as one of the foremost criminal practices in the country, largely thanks to our role in a number of high profile celebrity cases. These included the Jeremy Thorpe trial, the attempted kidnap of Princess Anne and the Steve Biko inquest.

A decade of growth for the firm, as we increased from 10 to 17 partners. We became well known for our commercial and private client business alongside our criminal litigation expertise, while our matrimonial and family practice developed rapidly. In 1989 we merged with Egerton Sandler.

Kingsley Napley became the go-to firm for white collar crime cases, and we acted in several notable cases, including the Guinness affair, and represented a number of high profile clients including Ian Maxwell, Nick Leeson and General Pinochet. In addition, we continued to expand our range of services, with the formation of our Clinical Negligence, Employment and Immigration teams.

We focused on expanding our corporate and commercial services, and acted in a number of notable M&A deals. Our Public investigations team played an integral role in the Hutton Inquiry into the Iraq war and the shooting of Jean-Paul de Menezes. We also provided assistance to the family of Madeleine McCann. In 2007 Linda Wooley became Managing Partner.

Thanks to our burgeoning reputation we expanded our work in a number of legal areas. Our Public Law team in particular have acted in many high profile inquests, including the 7/7 bombings and the Westminster Bridge terror Attack. In 2018 Stephen Parkinson became our Senior Partner.

In 2021 we moved to our new offices in Bonhill Street. Today, we are a highly-regarded, diverse firm recognised for our integrity, sensitivity and commercial excellence.
