In this year’s Global London coverage , we highlight the split between two groups of firms: those that are continuing to place big bets on London growth and those that are retrenching.
Here, we take a closer look at some of the firms putting their money where their mouth is by ramping up lawyer numbers or making eye-catching lateral hires over the last year.

Greenberg Traurig may not always be the first firm people think of for splashy London expansion but, now ranked 22nd in the headcount table with 156 lawyers in January 2025, it’s a firm that has been steadily growing. Partner count climbed by nearly a third last year to 55, against an 11% increase in headcount. And 2024 was not an anomaly. The firm features in the top 10 for increases in both partner and lawyer count over the last five years, with partner count up more than 77% and lawyer count up 75%.
It brought in no fewer than nine lateral partners in 2024 across a broader range of practice areas than some of its more narrowly focused Global London peers. These included a trio of construction-focused international arbitration partners from Pinsent Masons in July, including the UK firm’s former global international arbitration co-head Jason Hambury, as well as real estate finance partner Duncan Hubbard from Cadwalader in June.
‘Firms not only need larger headcounts but broader, more diverse practices’

King & Spalding jumped five places to number 34 in this year’s table on the back of year-on-year increases of nearly 26% in both lawyer and partner numbers. The firm also performed well on a five-year basis, increasing its lawyer headcount by nearly 62% and its partner count by just over 77%.

It made nine partner hires over the course of the year, six of which were partners at their former firms. Standout hires include its June hire of a four-partner funds team from Cadwalader, led by Legal 500 fund finance leading partner Samantha Hutchinson. The recruitment catapulted King & Spalding to a tier 1 Legal 500 ranking in fund finance, and complemented other transactional hires including high-yield capital markets partner Peter Schwartz, who joined from Paul Hastings in February.
In a sign of its long-term commitment to the City, the firm also executed an office relocation to 8 Bishopsgate. Announced in October 2023, the move saw the firm upsize to 41,000 square feet of space in the prime location.
‘The London market has grown substantially over the last 20 years or so and law firms have needed to scale-up to match demand’, says London managing partner Tom Sprange KC (pictured). ‘Firms not only need larger headcounts but broader, more diverse practices and specialities if they want to be competitive in London, at least outside of niches. We have been actively targeting key areas that our clients need support on, whether transactional, regulatory or disputes work.’
Paul Weiss
| London lawyer headcount (partners) |
215 (40) |
| Partner hires (laterals) |
19 (17) |
It would be impossible to look at the star performers of 2024 without referencing Paul Weiss. The firm leapt to number 13 in this year’s headcount ranking after entering the table for the first time at 45 last year. From 56 lawyers and 13 partners at the close of 2023, the firm finished 2024 with 215 lawyers (up 284%) and 40 partners (up 208%).
The firm’s small scale in the City until its bold relaunch in late 2023 under a team led by former Kirkland partners Neel Sachdev and Roger Johnson means its overall lawyer headcount has grown a staggering 696% in five years.
Its continued expansion means it finished in joint first place with Kirkland by increase in total partner numbers year-on-year, adding 27 new partners. And by total lawyer growth, the firm stormed to the lead, adding 159 lawyers compared to second-place Kirkland’s 45.
The scale of growth means that Paul Weiss alone accounted for nearly two thirds (62%) of the additional 255 lawyers hired across the whole of the Global London firms.
Paul Weiss also made the most partner hires of any Global London firm in 2024, bringing in 19 new partners, of which 16 were laterals. Six of these were from Kirkland, including a funds buildout kickstarted with the hire of James King in February and continuing with the hires of Jeremy Leggate, who joined as European funds co-head in August, David Pritchett and regulatory specialist Rev Raghavan and Prem Mohan, who joined later in the year.
The firm also made a further clutch of hires from the magic circle. Three joined from Clifford Chance, including Legal 500 high-value PE transactions leading partner Christopher Sullivan and banking and finance team co-lead Taner Hassan, whose moves were reported in December 2023. Meanwhile, five joined from Linklaters, including Legal 500 competition Hall of Famer Nicole Kar, whose move was also reported in December 2023 and who now serves as global co-chair of the firm’s antitrust practice.
Sachdev told Legal Business that the firm’s rapid expansion in London had been powered by its ability to attract ‘elite’ partners. ‘We now have a deep bench across all of the key teams to advise private equity and strategic clients on their global transactions.’
Paul Weiss has maintained its momentum into 2025, with notable hires so far including A&O Shearman’s Nick Charlwood, who in May joined the London restructuring practice Paul Weiss launched through the hire of Akin’s Liz Osborne last July.
‘The strategy for London has remained constant – we’ve always focused on asset managers’

Proskauer climbed two spots to 24 in this year’s table, with 148 lawyers and 50 partners – up 14% and 28% year-on-year respectively. By five-year growth the firm’s performance is more impressive. It finished fifth by overall five-year headcount growth, with lawyer numbers up 78% and partner count up 79%.

2024 saw the firm add eight new partners, seven of which were partners at their previous firms. Six of the hires joined its global finance practice and one, former Sidley investment funds head James Oussedik, its private funds group. The finance hires saw former legacy Allen & Overy banking head Philip Bowden join alongside partner Megan Lawrence, while Jake Keaveny, Warren Newton, and vertical hire Court Tisdale joined from Cahill.
‘The strategy for London has remained constant’, says Proskauer London office head Steven Davis (pictured). ‘Our strategy has always focused on asset managers across the full class of alternative assets. We’ve refined that to a focus on private capital. Our key practices address three things: the raising of capital, through our funds practice; the deployment of capital, which is a combination of equity and debt, and includes our secondaries practice; and the realisation of capital, with M&A.’
‘As those three main practice have grown, our adjacent practices in tax, regulation, and litigation, amongst others have grown as well.’
Davis says that this focus has been in place since he joined the firm in 2014: ‘When I was discussing with the then-chair what London might look like, we decided we’d focus on asset management clients and build strength and depth in the practices that those clients needed most.’
‘The goal is to put the right people in the right places so that you can build and develop the client relationships that you need’

Sidley Austin

206 (50) |
| London partner hires (laterals) |

Sidley ranked 14th this year, with a total of 206 lawyers in London including 50 partners. Though total lawyer count was down a little over 1%, the firm increased its partner headcount by 9%, with six partners leaving but nine joining.
These hires included a clutch of high-profile partners from Latham, which accounted for seven of the nine laterals Sidley brought in over the course of the year. Perhaps most notable was the firm’s August acquisition of a five-partner leveraged finance team led by Legal 500 acquisition finance leading partner Jay Sadanandan and Hall of Famer Sam Hamilton.
With a strong focus on finance – six of the firm’s nine laterals joined its global finance group, including five of the Latham hires – Sidley zoomed in on one of its core areas of high-value work. ‘Growth in itself isn’t an end game’, says London managing partner Tom Thesing (pictured). ‘You can put people in seats, but that isn’t the goal. The goal is to put the right people in the right places so that you can build and develop the client relationships that you need.’

Sidley explains its continued growth in London with reference to the same class of large asset managers as Proskauer. Thesing says: ‘Our client base is global, in particular our clients in asset management. This means that there’s very little that gets done in New York that doesn’t benefit us in London, and vice versa. Our clients are also big and broad enough that they require advice on a range of matters, from corporate and M&A to finance and regulatory.’
The data shows that Sidley has been consistent in its commitment to London. On a five-year basis, the firm has increased its lawyer count in the City by nearly 35%, and its partner headcount by nearly 14%.
And the firm has shown no signs of slowing, making six partner hires already in 2025, including Latham London finance co-chair Tania Bedi at the start of the year, Latham London corporate co-chair David Stewart in April, and a trio of Weil funds partners led by private funds head Ed Gander in May.
‘We’re investing in the firm’s growth on multiple fronts’

Simpson Thacher re-entered the top 10 by total London lawyer count this year with 254 lawyers, including 54 partners. The firm is the only one in the Global London to rank in the top five by all headcount growth metrics, with lawyer numbers up 17% and partner numbers up 35% year-on-year, and lawyer numbers up 145% and partner numbers up 144% on a five-year basis, with the trajectory for its growth set by former London head Jason Glover.

The firm made four partner hires in 2024, including Hadrien Servais from White & Case in July, who joined as European private credit team lead. It has followed up with a number of hires announced last year that joined the firm this year, including Sidley’s former leveraged finance co-head Bryan Robson, whose move was announced alongside William Gwyn at the end of the year, and leveraged finance partner Dan Peach from Linklaters, in a move announced in November.
Commenting on the growth, real estate PE partner and Legal Business deal star Wheatly MacNamara (pictured), who was announced as London managing partner in February 2024 and took over from Glover in October, says: ‘We’re investing in the firm’s growth on multiple fronts, including through our pipeline of talent and through strategic lateral hires to ensure we’re best positioned to meet our clients’ evolving needs.’
