Company chop and signing documents

Whether you need a company chop or common seal, how a Hong Kong company validly signs contracts and deeds, and how to control signing authority.

By DBMS GlobalLast reviewed: 18 October 2026

The answer first

Many Hong Kong businesses use a company chop, a rubber stamp bearing the company name, alongside signatures. Under the Companies Ordinance, however, a company is not required to have a common seal, and a chop is not a legal requirement for signing contracts. What matters legally is that documents are executed in a way the Ordinance recognises, by people with authority.

A document is validly executed by the company if signed by two directors, or a director and the company secretary, or, for a company with a single director, that director, and expressed to be executed by the company. Banks and counterparties often still ask for a company chop as part of their own procedures.

Ways a company can execute documents

MethodIn practice
Common seal (optional)Affixed and signed in accordance with the articles
Two authorised signatoriesTwo directors, or a director and the company secretary
Single directorWhere the company has only one director, that director signs
Authorised agentA person given authority by the board, for example under a board resolution or power of attorney
DeedsExecuted as above and expressed to be executed as a deed
Please noteThe articles of association and any bank mandate may impose additional rules. Contracts with particular formal requirements, for example property transactions, should be checked with lawyers.

Company chops in practice

  • Round chop or name chop: the company name, often in English and Chinese, used with signatures on contracts, invoices and bank documents.
  • Signature chop: some banks accept a chop together with authorised signatures under the bank mandate.
  • A chop does not by itself prove authority. Counterparties are entitled to ask who signed and whether they were authorised.
Key takeawayKeep company chops locked away and log their use. A misused chop can make it harder to deny a document that someone without authority signed.

Controlling signing authority

  • Set out signing authorities in a board resolution: who can sign what, and up to what value.
  • Align the bank mandate with that resolution.
  • Keep the chop and seal securely, with a usage log.
  • Review authorities when directors or staff change.
  • Retain signed originals or secure electronic copies of key contracts.

Electronic signatures

Hong Kong's Electronic Transactions Ordinance generally recognises electronic signatures for most commercial documents, with exceptions for certain documents such as wills, powers of attorney and some property and court documents. Where a document needs the company's execution, the same authority rules apply whether it is signed on paper or electronically.

  • Use a reputable e-signature platform with an audit trail.
  • Confirm that the counterparty and any bank accept electronic execution for the document concerned.
  • Keep the completed electronic record with the company's contract files.
