Disputes & Regulatory

Offering commercial, innovative and cost-effective solutions to your problem

In this section

Greenwoods GRM team members are first-class dispute resolution specialists

Even the best-run businesses can find themselves in a dispute from time to time. This can be within a supply chain, with advisers or even an internal conflict.

Disputes are always disruptive and can sometimes threaten the viability of a business. We advise on dispute avoidance as well as representing a wide range of businesses in the pursuit or defence of claims. We want to help you avoid problems, so it is best to get us involved as early as possible.

Our Disputes team boasts high-calibre lawyers who are recognised in the Legal 500 and Chambers & Partners as “leading individuals” and “rising stars” (click here to Meet The Team). Our commercially astute dispute resolution lawyers are experienced, exceptionally skilled and focused to achieve the best solution. The size and talent of our team means we can deal with a wide range of national and cross-border disputes cost effectively. We are regularly referred clients by larger London firms where a dispute requires a more personal, tailored and cost-effective approach

How do we deal with your dispute?

We take the time to understand a situation and discuss what “success” means to you before agreeing the best strategy to achieve your goals. With that comes an honest, realistic analysis of the options open to you: court proceedings, mediation, negotiation,  adjudication, insolvency proceedings and any other possibilities.

We always deploy strategic thinking and a creative approach to resolve your problem as quickly and cost effectively as possible.


Our approach to pricing sets us apart from many of our competitors and other law firms.

We start by carrying out a full cost-benefit analysis, making sure that our strategy is rooted in your budget. We have a dedicated in-house pricing manager with specialist knowledge of the relevant issues which may play out in your case.

Where other law firms might typically only offer an hourly rate cost option, we offer pricing options which reflect a more collaborative process, with your needs firmly placed at the centre of the process.  This includes fixed price and risk-sharing.  We can also call on established relationships with third party funders and insurers to assist in building a cost strategy.

Having developed a clear understanding of what is important to you, and the extent to which you want to assume or share price risk, the pricing choices can include:

  • traditional hourly rates;
  • fixed fees for the entire case and/or individual stages;
  • “cap and collar” arrangements;
  • conditional fee agreements (CFAs); and
  • damages based agreements (DBAs), our team being one of the first in the UK to successfully use them.

We will then document the arrangement so that there is clarity as to the terms of our engagement, and any assumptions and exclusions that may apply.

Our goal is to ensure that however the matter plays out, you feel you have had good value for money and no cost surprises.

Our Disputes team comprises highly experienced lawyers who routinely handle complex and high-value international disputes

International disputes require specialist legal advice due to the complex, and often high-value issues at stake in cross-border litigation.

Businesses’ supply chains mean that trade often crosses borders. Arbitration is the dispute resolution method of choice for many businesses, state entities and parties where a neutral, confidential resolution forum is preferred.

Our arbitration and international litigation team

We have a team of lawyers skilled in conducting litigation in the UK and abroad for and against foreign parties.  We have also acted in arbitrations under all the major institutional rules including LCIA, ICC, ICSID and UNCITRAL, across a variety of sectors such as banking and finance, construction and engineering, energy, oil and gas,  insurance, shipping, international trade and transport. The combined experience of our Disputes team in relation to arbitration and international litigation is outstanding which is augmented further by our team’s expertise in various sectors, including for example: oil and gas, Euan Palmer and construction, Howard Crossman.

In each case, our aim is to provide pragmatic and commercial advice, whilst exercising a flexible, cost-effective approach to international issues that maximises the opportunity for our clients to achieve the best result.

Data privacy law is fundamentally regulatory concern: compliance and enforcement is monitored by the ICO, an executive non-departmental public body, which has independent powers to issue fines for non-compliance. However, the GDPR also allows individuals to bring court claims for damages (both material and non-material, including for distress) alleged to have been suffered as a result of an organisation’s failure to comply with its data privacy law obligations. We can assist in both capacities.

  • Public authorities: advising on how data privacy law obligations differ from commercial organisations
  • Health and safety: advising on data privacy law obligations as part of wider health and safety law (for example assisting clients to collect, use and monitor personal data lawfully to ensure sustainable workplace reopening during the pandemic)
  • Corporate governance: advising on board-level data privacy law accountability obligations and governance practices which can withstand ICO scrutiny
  • Regulatory investigations: advising clients on handling supervisory authority (for example ICO) investigations from initial individual complaint to resolution
  • Litigation: assisting clients to defend claims brought by individuals arising from allegations of a breach of the GDPR (including non-material claims of distress, mental health issues or psychiatric harm)
  • High-profile: recent work has included advising a global charity on the data privacy law elements of a much-publicised working practices scandal and assisting a national political party in relation to a media-scrutinised data security incident involving inherently sensitive and private information.
    • Advising a national political party on a media-scrutinised data security incident involving inherently sensitive and private information
