About us

Haberman Ilett provides exclusively accounting expert witness and related services in UK and international litigation, arbitration, and alternative dispute resolution.  Founded in September 2013, we are the largest independent firm of our type in the country.

We provide expert evidence in matters arising from commercial and contractual claims, shareholder disputes, investment treaty claims, competition and anti-trust cases, and those arising out of corporate transactions.  We also act as the expert determiner, or for the buyer or seller, in completion accounts disputes.

We distinguish ourselves from our competitors by offering a truly independent service.  Where large firms are constrained by their wider commercial relationships, we are a dedicated forensic firm that combines the knowledge and experience gained by our team in the Big Four and other firms with the agility and focus that comes with being a specialist practice.

If there is an accounting or financial aspect to your dispute, please contact any of our partners or directors.

Leadership team

Our founding partners, Philip Haberman and Frank Ilett, are two of the best-known expert witnesses in the world.  Between them they gained more than 30 years’ partner experience before launching Haberman Ilett LLP in September 2013.  Initially with four fee earning staff, including Vikki Wall, who is now a partner, the firm focused on building a high-quality team that could take on substantial cases.

In September 2014, Valery Knyazev joined as partner and Debbie Revill joined as director.  Liz Perks and Bruno Augustin were promoted to partners in March 2015 and Graham Nunns became a director in January 2017.  By this time, the firm was made up of 38 fee earners working on cases where the damages claimed range from USD 10 million to more than USD 10 billion.

So far in our short history, members of the Haberman Ilett team have given evidence in the witness box 18 times and we have been involved in more than 100 cases.

Congratulations, Phil, on being appointed to the board of the LCIA. I’m sure you will bring a very valuable perspective to the board.

I just wanted to say how grateful I am for your fantastic work, professionalism and, of course, the moments of humour.

Valery Knyazev is simply the best for Russian-language matters.
