Who are A&O?

We’re a pre-eminent global law firm, operating in over thirty countries around the world.

We’re the only firm to have featured in the top five of the Financial Times Innovative Law Firm Awards every year since its creation, and the only firm to have won it four times. Last year we worked for 87% of Forbes’ top 100 public companies and we promoted 20 new partners around the globe.

This phenomenal success is built on the work of talented and motivated people who thrive in a supportive and collaborative environment, dedicated to delivering an exceptional standard of work for our clients. We’re ambitious and future focused, committed to growing our business and meeting the future head-on. We’re not afraid of change, and we believe in challenging the status quo.

Our track record of innovation is second to none. With our expansion into new jurisdictions, flexible working for partners, Fuse, aosphere and alternative resourcing options, such as Peerpoint, we are setting the standard for what a global law firm should look like.

We’re proud to have the resources, the passion and the mind-set to build solutions for the future, whatever it may hold.

With thousands of people in over thirty countries all over the world, we’re a business doing work of global significance.

We’re one firm structured as seven global practices; over half of our transactions involve three or more jurisdictions, and nearly three-quarters of the work we do draws on the resources of two or more of our offices.

Throughout our eighty-eight year history, we’ve led the market by finding new ways of meeting the challenges that our clients face. To deliver the standard of support that they expect, we have a world-leading base of expertise and a range of tools, such as margin matrix, our Legal Services Centre and our network of over 150 Peerpoint consultants.

Wherever your ambitions lie, we can provide you with the platform you need to make a difference, within the firm, the legal industry and the changing world around us.


Our banking practice has played a leading role in almost every major development in the modern financial markets and, with over 1,000 lawyers worldwide, it’s one of largest in the industry.

Insight: British American Tobacco

We assisted the lead banks on a USD 25 billion acquisition loan facility for British American Tobacco, to back the USD 49.4 billion acquisition of the 57.8% stake in U.S. peer Reynolds American Inc. which it did not already own. This was the largest deal in the European syndicated loan markets in 2017.

Working as a finance lawyer at the market-leading finance firm gives you exposure to a quality of work that is unrivalled among our competitors.

Our lawyers combine excellent transactional skills with specialist expertise in areas such as antitrust, tax, employment and pensions.

Insight: Electricity generation in Africa

We supported the Africa Finance Corporation and the Pan African Infrastructure Development Fund on the establishment of a joint venture to generate 1,575 megawatts of electricity.

With over 450 lawyers based all over the world, our ICM Team is one of the largest in the global legal industry. We enjoy a top-tier position across the full range of capital markets products, and we’ve played a big part in almost every major development in our field. Rapidly changing economic, political and regulatory conditions have made the last few years challenging, and we’ve helped clients address the fallout from several sovereign debt crises. As our focus shifts towards big-picture, long-term projects, we increasingly work with colleagues from other practice areas to develop innovative solutions that incorporate complex financing techniques.

Insight: MarginMatrixTM

We developed a market-leading IT solution to help our clients comply with the mandatory variation margin rules that now apply to the USD500 trillion OTC derivatives market. MarginMatrixTM covers regulatory requirements globally, template development, data collection, data scrubbing, negotiations, automatic drafting, delivery of legal opinions and the import of data back on the client’s systems for business as usual. MarginMatrixTM provides process efficiencies and economies of scale that no individual client could match on its own. We acted for eight global investment banks, and between them these eight clients have required over 25,000 negotiations.

Everyone at A&O takes real pride in doing their job well. It creates an inspiring atmosphere.

Insight: The Black Sea pipeline

We worked with South Stream Transport, part of Gazprom, in an ICC arbitration with Saipem relating to a gas pipeline from Russia under the Black Sea into Europe. The case was one of the largest construction arbitrations of recent years.

I really enjoy the fight of litigation; strategy, tactics, intensity and especially the highs\lows of winning and losing.‎ There's no feeling quite like it.

Our London-based Tax team works alongside colleagues in all jurisdictions to provide cutting-edge advice on the implications of transactions and strategies executed by some of the world’s largest companies and institutions.

Add to this the fact that tax law is constantly changing, and life is never dull.

Our culture

It’s time to find common ground.

We work to attract, develop and keep the very best people – and we don’t take them for granted.

All kinds of people work at Allen & Overy, but we have a few things in common. We’re united by an attitude, a desire to do more, to go above and beyond for our clients and each other. We foster a working environment based on collaboration and mutual respect, where everyone is trusted to do their very best work.

As important as that work is, we know that it’s also important for our people to have a life beyond it. Everyone at A&O is given the space and encouragement to pursue their interests outside of work and have access to clubs and events where they can discover new passions. They can also take part in our pro bono and community work programme that compliments their skills and ambitions.

Pro bono / Citizenship

Find out what you’re really made of.

With unrivalled depth of expertise and a presence in over thirty countries, we’re in a position to effect positive change on pressing issues all over the world, and help find solutions to society’s most serious problems. Our pro bono and community work is focused on two major themes – access to justice and access to education and employment – adapted to the needs and priorities of local cultures.

Last year 54% of our lawyers took part in pro bono work to a value of GBP 21.2m – but we try and use the skills of all of our people to their greatest effect, whichever part of the firm they’re from and whatever their area of expertise.

Our people are encouraged to get involved as much as possible in volunteering, to take on responsibility, and to

use it as an opportunity to develop their client-facing skills.

They’ve worked with global human rights organisations like INTERIGHTS and with Reprieve, fighting the death penalty and indefinite detention without trial. Qualified lawyers and trainees also advise at evening clinics in legal centres across London on a rota managed by a committed team of PAs. The opportunities to progress, both personally and professionally, are endless.

Smart Start 

Allen & Overy launched the Smart Start Experience in 2009 with the aim of giving young people from non-privileged backgrounds access to high quality work experience in the world of business. 

We wanted to find students who were bright and ambitious but who, because of their backgrounds, didn’t consider a career in law or business an option for them – or who didn’t know how to take the first steps on that career path.

Smart Start

Work experience

Since launching in 2009, our programme has supported over 1,100 young people and become an award-winning and accredited work experience scheme – the first in the legal sector to receive City & Guilds accreditation.

Our approach to diversity & inclusion

At A&O we recognise that people are different, in ways that we can see and ways that we can’t. We think that is a good thing. As well as creating a rich working environment that makes our work more enjoyable, the business benefits are clear. Being diverse and ensuring that we are inclusive helps us to attract the best people, innovate and understand and relate to our clients.
