What the Team is Known For

4 New Square is a leading set for costs law matters, and its barristers often represent clients in matters concerning litigation funding agreements. Its members work with many of the UK's leading litigation funders and ATE insurers, and also represent claimants and claimant groups in group actions, defendant organisations and solicitors' firms. Members advise on and draft litigation funding agreements and damages based agreements, and act for clients in costs claims relating to these agreements.

Lizzy Stewart is the set's senior clerk and CEO.

Strengths

4 New Square Chambers always has the best KCs and the best costs juniors available as required.

What distinguishes 4 New Square is not simply technical excellence in costs law, but their genuine understanding of the underlying litigation context in which those costs issues arise. Their costs and litigation funding team has a sophisticated grasp of group litigation structures, multi-firm coordination, funding architecture and the strategic implications of cost management in mass claims. Their depth of understanding is rare.

4 New Square Chambers has unrivalled strength across both the juniors and silks. It's not just technical costs expertise they bring, but also a real strategic and commercial angle with the analysis, which clients really value.

4 New Square Chambers offers careful, considered, practical costs advice. It has a niche area of expertise that other sets don't possess.
