Alan Karsberg


I am a specialist in investment, corporate occupier and landlord and tenant real estate work.


I qualified in 1996 and have worked at Berwin Leighton (now BCLP), subsequently becoming a partner in 2007 at Olswang and then CMS Cameron McKenna Nabarro Olswang. From 2000 to 2004, I was a lawyer at a US investment bank. I joined Fladgate in November 2018.

I specialise in commercial real estate, advising investors and corporate occupiers. I have particular experience and expertise in investment work (especially complex portfolio transactions, sales and leasebacks, and complex pre-lettings), and landlord and tenant work (acting for both landlords and major corporate occupiers).

I thrive on strong personal relationships with my clients, and seek to work with them in a way that suits them individually. I have enjoyed working with most of them for many years. I use my experience as a client from when I worked at a US bank as a constant reminder to see my work and approach transactions through a client’s eyes.

I enjoy the contrast and need to adapt between the often purely commercial approach of investor clients and the often highly bespoke and personal practical requirements of a corporate occupier.
