Analysis
What this data actually tells you
Professional, scientific, and technical activities in Hong Kong are anchored by substantial, formally-regulated professional bodies: the Law Society of Hong Kong (established 1907) reported 11,938 solicitors holding a current practising certificate as of November 30, 2025, with barristers separately regulated by the Hong Kong Bar Association; the Hong Kong Institute of Certified Public Accountants has over 42,000 members and over 18,000 registered students, and only HKICPA-registered CPAs may conduct statutory audits in Hong Kong.
Building-certification professions run through a distinctive statutory layer separate from the professional institutes themselves: the Buildings Department maintains statutory Authorized Persons’ Registers, covering six recognised disciplines — general practice surveyors, architects, structural engineers, planners, quantity surveyors, and building surveyors — who alone may certify building plans, alongside separate specialist Structural Engineers’ and Geotechnical Engineers’ registers. Counterparties verify a lawyer, accountant, or building-certification professional’s actual current registration with the relevant specific body directly.
