Our payments practice

Payments play a vital role in our day to day lives: consumers and businesses make and receive millions of payments every day on the UK financial system’s rails. Understanding and operating within this complex and rapidly evolving space can be challenging whatever the nature or scale of your business, or your place in the payment chain.

Our payments team acts for clients from all parts of the payments ecosystem from banks, payment service providers and e-money issuers to merchants and merchant acquirers, and regulated and unregulated technology businesses, alike. 

The breadth and depth of our practice in this rapidly evolving sector enables us to advise on the full spectrum of regulatory, transactional, and commercial issues affecting the payments industry. Our areas of expertise include:

  • Open Banking and the development of APIs;
  • PSD2 (including strong customer authentication, conduct of business, incident reporting and other requirements);
  • the authorisation and ongoing regulation of e-money issuers, including requirements that relate to the issue, redemption and safeguarding of e-money;
  • ICOs, cryptocurrency and crowdfunding;
  • digital wallets and the structure and regulation of fiat and cryptocurrency exchanges;
  • blockchain and the use of distributed ledger technology in the payments system;
  • AML / CTF / KYC requirements and the Wire Transfer Regulations;
  • regulated and unregulated lending;
  • the format and content of consumer and business Terms and Conditions for various payment, e-money and technology service providers; and
  • other payments legislation (including the Payments Account Directive, the Cyber Security Directive) and transaction services.

Client feedback

They are always very responsive and on the money with their advice. I know that when I call asking for advice, as soon as I get on the phone I will get the advice I am looking for. They are very reliable and hands-on in their approach, I rarely have to question their advice … their advice is always concise, practical and to the point

They are very knowledgeable on fintech, give good value for money, get really involved and solve problems. They’re probably one of the best fintech firms in London. They’re very efficient, it might take other firms ten hours but Fox Williams will get in done in around two hours. I’m not sure what they could improve. They are doing very well for us. I think they will grow and hopefully they’ll keep the same level of service
(Chambers UK, 2019)

I’m particularly impressed with how responsive Chris Finney and Jonathan Segal are to client demand. They have always shown an ability to see through clients’ problems and offer commercial solutions which is a great thing to have on your team. They don’t come across as stereotypical law firm partners. [They] are very knowledgeable, pragmatic and attentive to detail
