Commercial litigation: mid-market Tier 6

Marriott Harrison LLP regularly attracts high-value and complex disputes work, and has experienced growth in relation to international litigation. Tamar Halevy has particular expertise in company and shareholder disputes, while Jim Mackie acts for companies and individuals in claims for breach of contract, professional negligence, breach of trust, and fraudulent and negligent misrepresentation.

Practice head(s):

Other key lawyers:


The commercial disputes team provides real commercial support to the clients of the firm and punches well above its weight. One of its core strengths is its ability to provide dispute resolution support across a range of areas and industry sectors. The work which is undertaken is well thought out and structured and exceptionally well executed. It always seems to get the best possible result for the client.

Jim Mackie brings a real wealth of experience to commercial disputes. He seems to have an excellent rapport with clients and is fantastic at putting together and managing the right team for the case. He understands the commercial realities of the disputes and is great at focussing on the client’s commercial objectives.

The Marriott Harrison dispute resolution team is different to many of its competitors because of the high-standard, partner-led service whereas if we were to instruct one of the large City firms our work would be dealt with on a day to day basis by more junior lawyers. The team also has exceptional front-line court experience which differentiates them from many of their larger competitors who do not get into court as much.

We have worked primarily with Tamar Halevy who heads up the dispute resolution team. Tamar has been fully involved in, and on top of, all the details and complexity of our case right from the beginning and all the way through. She has provided sound legal advice and has been tenacious in seeking to achieve a commercial outcome for us in the case. She has constantly made herself available to communicate with us on the matter.

The firm offers very cost-effective approach and maintains good quality of services, which is a distinguishing feature.

Tamar Halevy is always there to provide a practical advice and ensure the most effective strategy.

Tamar Halevy and her team at Marriott Harrison were uniquely equipped to advise me on the particularly intricate details of my case with regard to legal, financial and social aspects. Tamar’s CV impressed me in the selection process with her experience in financial matters, international M&A and dispute resolution.

Tamar Halevy – accessible, focussed, diligent, patient and pragmatic.

Tamar Halevy is an excellent litigator. Tamar has always seen the best route forward for the pieces of litigation on which we have worked together. She is very practical in her approach, and avoid unnecessary wasting of time and resources. She takes counsel’s advice well, and never has a difficulty in understanding it.

In my experience Brett Israel turns around work very quick, and is an excellent leader of his team. There is never a wasted moment in his cases.

Tamar Halevy is exceptionally clear and definitive in her advice and explanations. Her oral delivery is unparalleled for a firm of this size.

They have excellent experience and strength in this area. I would compare them very favourably with other firms.

Tamar Halevy is superb – experienced, unflappable and great with clients.

Tamar Halevy, who leads the dispute resolution team, is really excellent: very knowledgeable in company law, experienced in shareholder disputes, hard-working, possessed of fine drafting skills and most enjoyable to work with.

The Lex 100 Verdict

With a ‘broad range of corporate work on offer’ and a small intake, Marriott Harrison has a strong reputation for training and social culture. As a trainee summarises: ‘I chose Marriott Harrison because of the people. The small intake meant that I would be able to get stuck into transactions from an early stage and have a good amount of client contact’. As a Lex 100 Winner in four categories - job satisfaction, quality of work, social life and approachability of supervisors - the firm offers a ‘close relationship with senior solicitors’ and ‘lots of early responsibility’. One trainee adds that ‘I had a paralegal position there and I realised that it was exactly the type of firm I wanted to train at’. Negatives included problems with IT systems and the challenge of multi-tasking in a busy seat, but trainees appreciate being given ‘autonomy and responsibility’. Highlights include ‘organising a buy back with little supervision’, ‘completing my first deal in the corporate team’ and ‘helping to organise social events like the five-a-side football squad’. Marriott Harrison offers opportunities for trainees to sit on the CSR committee, as well as volunteer with organisations like Age UK Camden and Friends of Essex and London Homeless: ‘the firm has a great relationship with its CSR partners and is fully committed. This continued throughout the pandemic; we worked with our partners to keep CSR going which was great’.
