Extended data
Steel seal is our "common seal". This steel seal is the "seal" referred to in the Companies Ordinance and the contracts signed by most companies. As long as the company has prepared this seal, only by stamping this seal can it meet the conditions for signing the house deed, otherwise it will be just an ordinary contract.
The occasions where a company usually needs to affix its official seal include: real estate sales contracts, equity transfer contracts, mortgage contracts, loan contracts, stocks and other securities.
The new Companies Ordinance, which came into effect on March 3, 20 14, has been revised compared with the old Companies Ordinance-from now on, Hong Kong companies can have no corporate seal. Although Hong Kong companies no longer need to prepare seals, most newly established Hong Kong companies will choose to prepare seals because of the deep-rooted "seal consciousness" in the Chinese community.
In other words, we may see more and more Hong Kong companies without any "official seal" or "seal". For such a company without a seal, Article 127 (3) of the new Companies Ordinance stipulates the way to sign documents: two directors sign, or one director and the company secretary sign.
