The call

Mallesons keeps its ranked APAC deal practice intact after the split, while King & Wood tests unproven North America offices against established China-only firms and cross-border deal headwinds.

King & Wood Mallesons is a large law firm that split into two separate companies on March 30-31, 2026. Mallesons, which covers Australia and Singapore, keeps its top ranking in mergers and acquisitions because it has deep connections with local regulators and protection from liability rules that are hard for competitors to replicate. King & Wood, which operates in China, Hong Kong, Japan, and the US, faces a real challenge from well-established Chinese law firms like Zhong Lun and JunHe that already have strong client relationships there, plus uncertainty about whether its new US offices will attract enough business. Both firms use Harvey AI to help with routine legal work like reading contracts and research, but this technology cannot replace the licenses and insurance that lawyers need to practice, so it gives them only a modest edge. The biggest question mark is whether King & Wood can build real revenue in North America and whether the split will cause partners or clients to leave in the coming months.

Why
01
AI pressure: Harvey AI. Harvey AI compresses document review and due diligence work but cannot replace bar admission or liability cover partners hold. Could AI do the core job? Unlikely.
02
Bigger players: Zhong Lun, JunHe, Fangda, Han Kun (China); HSF Kramer, Allens, MinterEllison, Clayton Utz (Australia). Established rivals in both new markets compete for the same partners and mandates while each half of KWM proves itself standalone. Could a giant copy it? No, they are blocked.
03
What protects it. Bar admission requirements, professional liability rules, and retained Band 1 rankings on major APAC deals.
What would change this call
Mallesons partner attrition rate over the 2 quarters following the March 2026 split. High departures would show clients and talent are shifting to HSF Kramer or Allens.
Whether King & Wood's new Vancouver and LA offices land repeat cross-border mandates by mid-2027. Weak traction would show Zhong Lun or JunHe are better positioned for China-linked deals.
Whether Mallesons or King & Wood appear atop 2026-2027 Australia/APAC M&A league tables. Falling rank would show HSF Kramer, Allens or Ashurst are capturing the deal flow.
Key numbers
  • Mallesons has 1,200+ lawyers post-split (2026-03-29)
  • Mallesons promoted 9 new partners (2026-06-05)
  • King & Wood opened Vancouver and LA offices (2026-03-31)
Named risks
  • Partner and client attrition in the immediate post split window. Severity: high
  • King & Wood's unproven Vancouver and Los Angeles offices fail to gain traction. Severity: medium
  • China only incumbents (Zhong Lun, JunHe, Fangda, Han Kun) capture standalone King & Wood market share. Severity: medium
  • US China geopolitical tension reduces cross border deal flow both firms depend on. Severity: medium
  • Referral revenue leakage between the two split entities materializes in post split financials. Severity: medium

Questions people ask
Is King & Wood Mallesons still one law firm?
No. The Sino-Australian partnership formally dissolved 30-31 March 2026 into two independent firms: King & Wood (China, Hong Kong, Japan, US) and Mallesons (Australia, Singapore), ending a merger that began 1 March 2012.
Is Mallesons doing well after splitting from King & Wood?
Mallesons retained Band 1 Chambers rankings in banking/finance, capital markets and M&A in Australia as of 2026, reports 1,200+ lawyers, and promoted 9 new partners effective 1 July 2026, per its own announcements.
Could AI replace lawyers at King & Wood Mallesons?
KWM adopted Harvey AI in 2025 and won an FT Innovative Lawyers award for it in May 2025, but court appearance rights and professional liability advice remain restricted to licensed lawyers, so AI displaces document review and drafting, not admission-bearing legal work.
Who is King & Wood's biggest competitor in China now?
China-only incumbents Zhong Lun, JunHe, Fangda Partners and Han Kun Law Offices are named rivals; a Law.com piece from 15 December 2025 quoted rival partners saying standalone King & Wood 'has a lot of catching up to do.'
Why did King & Wood Mallesons split up?
On 8 December 2025 the China and Australia partnerships announced they had jointly agreed to terminate cooperation, citing 'different strategic horizons,' with the formal separation taking effect 30-31 March 2026.
Who owns King & Wood Mallesons?
It was a private partnership structured as a Swiss verein, not publicly traded and with no external investors, standard for major law firms in Australia, China and Hong Kong; both successor firms, King & Wood and Mallesons, remain privately held partnerships.
