03Our approach

In-country insight. UK-standard governance.

We pair a detailed understanding of West African legal and commercial practice with the rigour expected by UK and international boards, lenders and regulators.

  • Regional depth

    Advice grounded in how laws are applied in practice, not only in how they read on paper.

  • Cross-system fluency

    At home across common-law, civil-law and customary systems, and across anglophone and francophone markets.

  • Commercial focus

    Advice tied to your transaction, timetable and risk appetite, with clear recommendations rather than open-ended memos.

  • Compliance by design

    Every engagement is built to stand up to scrutiny from regulators, auditors, lenders and investors.

How an engagement works

  1. Scope

    We define the question, the jurisdictions involved and what a good outcome looks like for you.

  2. Assess

    We review the legal, regulatory and commercial position and identify the risks that matter.

  3. Advise

    We set out clear options and recommendations, with the trade-offs made explicit.

  4. Deliver

    We support execution through negotiations, filings, approvals and ongoing compliance.
