Bringing business sense to international arbitration.
International arbitration does not require technical analysis alone. It requires experts who understand the factual record, the legal issues and the business context, and who can provide evidence grounded in both rigorous analysis and established business practice.
Accuracy is built for that task. Our difference lies in the combination of arbitration expertise and real business experience. Our experts also advise investors, corporates and financial institutions on transactions, strategy, restructuring, crises and major projects. That experience allows us to test assumptions, assess commercial plausibility and stand behind our conclusions with credibility and clarity.
Our partnership has been built around leading experts in valuation, damages, economics, accounting, forensic analysis, delay, engineering and project disciplines. They work as one firm, across disciplines and geographies, with common standards and a shared commitment to excellence.
Our analyses are robust and our conclusions are useful because they are tested from every material angle: financial, factual, technical, sectoral and legal.

What sets our international arbitration practice apart?
A partner-owned independent expert firm
Accuracy is fully owned by its partners. Our model supports long-term thinking, senior accountability and independent judgement. Our experts are not a collection of individual practices. They work within one partnership, with shared methods, training and standards.
Experts grounded in real business practice
Our arbitration work draws on experience beyond disputes: transactions, M&A, financial advisory, restructuring, strategy, crisis situations and project work. This gives our opinions commercial credibility and helps counsel test damages theories against how businesses, investments and projects actually operate.
Integrated evidence for complex cases
Many disputes require more than separate opinions on quantum, delay, valuation or technical issues. Our multidisciplinary teams build integrated analyses that connect these disciplines into one coherent framework, including co-testifying where this helps the tribunal test related issues together.
Sector depth where it matters
Our experts work across sectors where financial, operational and technical issues are closely linked, including aerospace and defense, beauty and luxury, construction and engineering, digital technology and software, energy and environment infrastructure, financial services, mining and metals, pharmaceuticals and healthcare, telecommunication and digital infrastructure and real estate among others.
Clear and useful conclusions under scrutiny
We listen carefully, challenge assumptions and state our conclusions clearly. Our reports and testimony are designed to make complex financial and technical issues understandable and useful without oversimplifying them.
Our arbitration expertise
INVESTMENT ARBITRATION
Investment arbitration requires more than the application of valuation techniques to a treaty claim. It requires a grounded understanding of how investors assess risk, allocate capital, finance projects and respond to incentives and regulatory change. It also requires avoiding speculative calculations that are detached from the factual record.
Accuracy supports both investors and states with damages and valuation evidence that connects legal issues to the economics of the investment. We assess issues such as causation, expectations, regulatory impact, financing constraints and value scenarios using methods that are well-established, transparent and anchored in the evidence.
Our reputation also reflects our independence, our regular work for both states and investors, and our experience advising investors, governments and financial institutions across the globe.
COMMERCIAL ARBITRATION
Damages in commercial arbitration often turn on whether the claimed loss makes sense in light of the underlying contract, transaction, business plan or market context.
Accuracy approaches these disputes as both arbitration experts and business advisers. We test damages theories against the commercial realities of how deals are negotiated, businesses are valued, contracts are performed and risks are allocated. This is particularly important in post-M&A disputes, shareholder disputes, long-term contracts, pricing disputes, manufacturing claims and complex lost-profit cases.
Our role is to explain to tribunals what happened, what would likely have happened absent the alleged breach, and how any loss should be measured.
CONSTRUCTION ARBITRATION
Construction arbitration requires the connection of programme, cost, contract and project reality. Delay and quantum cannot be analysed in isolation where the factual record is fragmented, schedules are disputed and project narratives have evolved over time.
Accuracy’s construction teams combine delay, quantum, engineering, project management and financial expertise. We assess critical path issues, disruption, cost overruns, productivity, valuation and damages within a coherent project framework.
This integrated approach is particularly valuable on major infrastructure and industrial projects, where tribunals need clear evidence on what drove delay, what costs followed and how those issues connect to the parties’ respective positions.
