Company Chops in Hong Kong: Legal Requirement or Business Habit?

Ask for a document to be "chopped" in Hong Kong and everyone knows what you mean. The company chop is everywhere — yet legally, Hong Kong left the mandatory seal behind more than a decade ago. Understanding which chop matters, and when, saves real confusion.

Three different "chops"

Hong Kong practice distinguishes several stamps that outsiders often mix up:

Common seal — the embossed metal seal pressed into paper. Under the Companies Ordinance (Cap. 622), in force since 2014, keeping one is optional. A company can execute deeds by the signature of two directors, or a director plus company secretary.
Company chop (round chop) — the round inked stamp with the company name, used on contracts and official letters. No statute requires it, but it is the workhorse of daily business.
Signature chop / small chop — a rectangular stamp, often reading "For and on behalf of [Company]", stamped above an authorized signature on cheques, invoices and bank forms.

What the law actually requires

A Hong Kong company is bound by the signatures of persons acting with authority. The chop is evidence the document went through the company — useful, expected, but not the source of legal force. The Electronic Transactions Ordinance (Cap. 553) additionally recognizes electronic signatures for most commercial documents (with carve-outs like wills and certain property documents), and government transactions may require digital certificates from recognized certification authorities.

Where you'll still need a chop in practice

Banks: account opening forms, cheques and instructions routinely expect the signature chop alongside authorized signatures.
Cross-border business with the mainland: mainland counterparties treat stamped documents as the norm — an unstamped contract can stall simply because it looks incomplete. Context on the mainland system is in electronic seals in China.
Invoices, receipts, delivery notes: a chopped invoice is still the expected look across most industries.

Designing a Hong Kong chop

The classic round chop carries the English name around the top arc, the Chinese name around the bottom (or vice versa), and a plain center — effectively a bilingual layout. The bilingual seal template matches this structure, and the rectangular "for and on behalf of" style can be built from the corporate seal template. Blue or purple ink dominates; red is common for chops used with mainland-facing paperwork. Design one in the online seal generator, export a transparent PNG, and use the PDF stamping tool to chop digital documents cleanly.

FAQ

Is a company chop legally required in Hong Kong? No statute requires one. Deeds can be executed by signatures alone since 2014, and ordinary contracts bind through authorized signatures.

Can I rely on a chopped document without a signature? Risky. Courts look to authority; a chop without an authorized signature invites disputes about who applied it.

Is an image of our chop in a PDF legally effective? It carries the same evidentiary role as the physical chop's appearance, but proves little by itself — see are image seals legally valid?. For enforceable e-execution, use a recognized e-signature.
