Partner

What can I do for you

Brett is a highly regarded partner in our Family team. He provides expert advice across the whole spectrum of family law including divorce, financial matters, cohabitation and private law children issues (where a child shall live, contact arrangements and schooling matters). 

He has a particular focus on complex, financial disputes arising on divorce/separation, often with international/cross border matters.  Many of his cases involve issues around the valuation and sharing of businesses, pensions, properties, carried interests and trusts.

Brett also works closely with our private wealth team advising clients on wealth preservation and drafting both pre and post nuptial agreements. 

Supporting your ambitions

With years of experience, Brett offers expert insight and trusted judgement, helping clients navigate complexity and focus on what truly matters. He works closely with clients to understand the issues, helping them to make confident decisions and take action with purpose.

Brett also collaborates with his network of financial, pension, and property advisers, as well as his expert colleagues at Mills & Reeve, to ensure clients achieve the best possible outcome in their matter.

As one client commented, “The advice and service that I received was first class. Brett is quick, articulate, pragmatic and always a few steps ahead. The team were able to resolve my situation quickly and to my utmost satisfaction. The advice I received allowed me to get the best outcome, whilst importantly being practical and managing my costs.”

What our clients say about us

  • I think Mills & Reeve are a wonderful firm. The support they have provided to us in a really difficult area has been brilliant, collaborative and commercially minded. The team were absolutely wonderful and a joy to work with. Amazing advice and support and a real collaborative effort with us. I can't thank them enough for getting us through some really tough times and doing so with an amazing can-do attitude.
  • They are friendly, fast, always available and always on top of the game. I tend to judge my legal team against the other side's legal team and never doubt Mills & Reeve is the better of the two.
  • All interactions have been very clear. Responses to questions have always been very swift and unambiguous. Our company, and my family, have used various services in Mills & Reeve with the same level of satisfaction.
  • I value the fact that Mills & Reeve are recognised as a good place to work in the UK Best Companies survey. This aligns with the values of our business and means that Mills & Reeve can share what is required to achieve this status with our business.
