Company limited by guarantee. This is the structure most large Hong Kong charities use. The governing instrument is the articles of association filed with the Companies Registry, so every exemption clause is public and every later amendment needs a members' resolution and a filing. In exchange the organisation gets separate legal personality, limited liability and a governance framework the Department already recognises. Directors stay bound by their statutory duties, so the conflict rules in the articles work alongside the obligations covered in our company incorporation and secretarial documents.
Registered society. A society applies to the Societies Officer, an office within the Hong Kong Police Force, within one month of establishment under the Societies Ordinance (Cap. 151). Registration is quick, which explains its popularity with community groups, but a society is not a separate legal person, so office bearers can carry personal exposure for its debts. Constitutions drafted for the Societies Office concentrate on membership and committee procedure, and their silence on funds, remuneration and dissolution is the commonest reason an exemption application comes back for amendment.
Charitable trust. The governing instrument is a trust deed and the charity has no legal personality: the trustees hold the assets and contract in their own names. Endowment style giving still uses this route, sometimes with incorporation of the trustees under the Trustees Incorporation Ordinance (Cap. 306). The deed needs the same objects, funds, conflict and dissolution provisions, and the trustees carry fiduciary duties beyond anything the Department asks for.
