Why "Best" Depends on the Right Fit, Not Just a Search Result

Searching "best international tax lawyer in London" returns dozens of firms, directories and comparison sites — but international tax and private wealth work is rarely a commodity service. The right lawyer for a straightforward personal tax return is not necessarily the right lawyer for a multi-jurisdictional trust restructuring, a cross-border succession dispute, or a notarial matter that needs to be recognised in a foreign court. Choosing well means matching the lawyer's specialism to the actual problem, not just their ranking on a search page.


What to Look for When Choosing an International Tax Lawyer in London


1. Recognised Specialist Accreditation and Academic Grounding

Formal credentials matter more in this field than general legal qualifications. The TEP (Trust and Estate Practitioner) designation, awarded by STEP (the Society of Trust and Estate Practitioners), is one of the clearest markers of specialist expertise in cross-border tax, trusts and succession planning. It signals that a lawyer has met rigorous professional standards specifically in this area, rather than practising it as a sideline to general commercial law.


Academic depth matters too. A postgraduate qualification focused specifically on tax law — rather than a general law degree — indicates sustained, formal study of the subject rather than expertise picked up incidentally through practice.


2. Genuine Cross-Border Experience

International tax problems rarely stay within one jurisdiction. Look for a lawyer who regularly handles matters spanning multiple tax authorities — including HMRC disputes that intersect with foreign tax positions, double taxation treaty questions, and structures that need to work coherently across borders, not just in the UK.


3. Notarial Authority for International Documents

Many cross-border matters — property transactions abroad, corporate documents for overseas use, powers of attorney recognised in foreign jurisdictions — require notarisation, not just legal advice. A lawyer who also holds appointment as a Notary Public (particularly a City of London Notary) can handle both the legal strategy and the document authentication in one place, which saves time and reduces the risk of documents being rejected abroad.


4. Breadth Across Related Specialist Areas

International tax rarely exists in isolation from private wealth and succession planning, or from dispute resolution when HMRC or a foreign authority challenges a position. A lawyer who covers these adjacent areas can see the whole picture, rather than referring a client out at the first sign of complexity.


Sheikh Najam TEP: Private Wealth & International Tax Lawyer, London

Sheikh Najam TEP holds an MA in Tax Law from the University of London, with a focus on UK, EU and International Tax Law — providing an academic foundation that sits directly behind his cross-border advisory work. He practises from Fox Court, 14 Gray's Inn Road, Holborn, London, offering advice across four specialist areas:

  • International Corporate Tax & Structuring — advising businesses and individuals on tax-efficient, compliant structures that work across jurisdictions.

  • Private Wealth & Succession Planning — trusts, estate planning and cross-border succession for high-net-worth individuals and families.

  • Notarial & Cross-Border Legal Services — notarisation of documents for use internationally, drawing on Sheikh Najam's standing as a City of London Notary.

  • Dispute Prevention & Resolution — helping clients avoid and, where necessary, resolve disputes with HMRC and overlapping tax authorities.

This combination — international tax lawyer and notary, private client specialist and dispute resolution advisor — is relatively unusual in the London market, where these functions are often split across separate practitioners.


How to Verify a Lawyer's Expertise Before Instructing Them

Before instructing any international tax lawyer, it's reasonable to check:

  • Professional accreditation — is the TEP designation, or equivalent, verifiable through STEP's own records?

  • Notarial appointment — is the individual a practising Notary Public, and with which faculty?

  • Published expertise — does the lawyer publish substantive articles on the specific issue you're facing (double taxation treaties, HNW estate planning, cross-border disputes), or only generic marketing copy?

  • Direct access — can you speak to the lawyer directly, or only to a case handler?


Sheikh Najam TEP publishes detailed articles on these exact topics — including double taxation treaties, high-net-worth estate planning, and resolving international tax disputes — on the Sheikh Najam TEP blog, which is a useful way to assess depth of expertise before making contact.


Next Steps

If your situation involves cross-border tax structuring, succession planning across jurisdictions, or a document that needs notarisation for use abroad, the most efficient first step is a direct consultation rather than a general enquiry.
