    Asset 2

    International Arbitration

    An age of globalisation. Businesses trading across borders. Governments welcoming outside investors. As foreign markets provide significant opportunities for companies to expand, there is a greater risk of legal disputes. International Arbitration has become a preferred method of cross-border dispute resolution for its neutral forum, as well as the parties’ ability to select arbitrators who are experts in the field in question, and the flexibility to influence the rules of the proceedings.

    StoneTurn has extensive experience providing quantum damages calculations, analysis and investigative expert witness services in complex international arbitrations. Our team leaders have been publicly recognised in the legal community, and testified on international cases under arbitration rules such as ICC, LCIA, LMAA, SAL and UNCITRAL, across a range of industries.

    Asset 2

    Data Science & Analytics

    Businesses are generating vast amounts of data across a growing number of locations at a rapid pace. While data can be used to measure or create operational efficiencies, it can also be used to prove or disprove facts in legal disputes and investigations, to identify financial reporting issues, as well as to measure the effectiveness of ethics and compliance programmes.

    StoneTurn analyses volumes of complex financial, accounting and business data; creates dynamic visual models; and extracts key insights in order to provide a factual basis to draw qualitative conclusions and defend business decisions and activities. In addition, clients rely on us for clear strategies on how to align their data with specific objectives.

  • Forensic Technology
    Asset 2

    Forensic Technology

    Significant advances in technology. A proliferation of data. Confidential information is more accessible by various personal devices. In the face of government and internal investigations, employment litigation and patent infringement matters, digital information can often make or break the outcome. And, with the staggering increase in volume and sources, culling through electronically stored information can be a time-consuming and costly process.

    StoneTurn’s proven team of digital forensics experts partners with companies, attorneys and their clients to efficiently capture, analyse and preserve electronically stored information in response to virtually all types of legal disputes, investigations, and allegations of compliance failures, handling every phase of the investigation with the utmost skill and care.
