Shareholders' agreements: agree before you disagree

Why founders and investors need a shareholders' agreement, what it should cover, and how it works with the articles.

By DBMS GlobalLast reviewed: 18 October 2026

The answer first

A shareholders' agreement is a private contract between the shareholders, and usually the company, that sets out how the company will be owned and run, and what happens when things change. It is not required by law, but where there is more than one shareholder it is one of the most valuable documents a company can have, because it is signed while everyone still agrees.

It is private and not filed with the Companies Registry, unlike the articles. It should be consistent with the articles; where they conflict, problems follow, so draft them together.

When you need one

  • Two or more founders starting a company together.
  • An investor buying into the business.
  • Family members holding shares across generations.
  • A joint venture between companies.
  • Key employees receiving shares.
Key takeawayThe best time to agree what happens when a founder leaves is before anyone wants to leave. Afterwards, every term becomes a negotiation.

Common gaps

  • No mechanism to value shares when a shareholder leaves.
  • No resolution of deadlock between 50:50 shareholders.
  • No obligation on a departing founder to transfer shares.
  • Articles left in model form, conflicting with the agreement.
  • The company not made a party, limiting enforcement.
Legal advice requiredShareholders' agreements are legal documents with long-term consequences. They should be drafted and reviewed by Hong Kong lawyers, with tax input where shares or options are involved.
