Shareholders' Agreement vs Articles of Association in Hong Kong: 2026 Guide

Quick answer: In Hong Kong, the articles of association are the company's public constitution, filed with the Companies Registry and binding on the company and all members under section 86 of the Companies Ordinance (Cap. 622). A shareholders' agreement is a private contract between some or all shareholders covering matters the public document should not disclose. The articles bind everyone who becomes a member; the shareholders' agreement binds only the people who signed it.

Most founders sign both documents on the same afternoon and never read either again, until a minority shareholder wants out, a co-founder stops turning up, or an investor asks to buy 20% and nobody can agree on the price. At that point the two documents decide who has leverage.

Volume makes this matter more, not less. Companies Registry statistics released in January 2026 show 195,343 local and re-domiciled companies were newly registered in 2025, taking the total to 1,557,103. Almost all started as private companies limited by shares, and most adopted the model articles in the Companies (Model Articles) Notice (Cap. 622H) unamended.

What are the articles of association in Hong Kong?

The articles are the rules for running a Hong Kong company: how directors are appointed and removed, how board and shareholder decisions are made, how shares are issued and transferred, notice periods, and dividends. Every company must have them, and they are delivered to the Registrar with the incorporation form (Form NNC1 for a company limited by shares, NNC1G for a company limited by guarantee).

Three features matter commercially:

• They are a statutory contract. Section 86 of Cap. 622 gives the articles effect as a contract between the company and each member, and between members. A shareholder can sue the company, and another shareholder, to enforce them.
• They are public. Anyone can inspect them on the Companies Registry e-Services Portal, including competitors and counterparties reading your transfer restrictions.
• They can be changed by majority. Section 88 allows alteration by special resolution, which under section 564 needs at least 75% of votes cast. Minority protection therefore comes from the general law, not the articles alone.

Model articles versus bespoke articles

Cap. 622H contains model articles for private companies limited by shares (Schedule 2), public companies (Schedule 1) and companies limited by guarantee (Schedule 3). A company that files no bespoke articles is deemed to adopt the relevant model. The model is well drafted and fine for a single shareholder, but thin for two or more founders because it says little about deadlock, reserved matters or exit.

What is a shareholders' agreement?

A shareholders' agreement is a contract between shareholders, often including the company, governing how they exercise their rights. Being private, it is not filed or inspectable, and can hold commercially sensitive terms: valuation formulas, dividend policy, founder vesting, non-compete obligations and deadlock mechanics.

The distinction that matters is remedy. Breaching the articles is a breach of a statutory contract that the company or any member can enforce. Breaching a shareholders' agreement normally gives a right to damages against the party in breach, and possibly an injunction, but does not by itself invalidate a company decision. If the company is not a party, it is generally not bound at all.

Articles vs shareholders' agreement: side-by-side

Aspect	Articles of association	Shareholders' agreement
Legal basis	Companies Ordinance (Cap. 622), ss. 75 to 88	General contract law
Who is bound	The company and all members, present and future	Signatories only, plus the company if it is a party
Public access	Yes, filed and inspectable at the Companies Registry	No, private
Amendment	Special resolution, 75% majority (ss. 88, 564)	Unanimous written consent of the parties, unless agreed otherwise
Filing	Form NAA1 within 15 days of the alteration taking effect (s. 88(3))	None
Breach remedy	Enforcement as a statutory contract; declaration or injunction	Damages, injunction, specific performance in limited cases
Best used for	Mechanics that must bind future shareholders and be visible to banks and investors	Valuation, vesting, exit rights, reserved matters, confidential terms

Which document wins when they conflict?

As between the company and its members, the articles prevail, because they are the constitution the company must act on. As between the shareholders who signed it, a shareholders' agreement can create personal obligations enforceable even where the articles say otherwise.

The leading authority is Russell v Northern Bank Development Corp Ltd [1992] 1 WLR 588, still applied in Hong Kong. A clause in the articles purported to stop the company increasing share capital without unanimous consent. The House of Lords held the company could not be bound by a provision fettering its statutory power, but the undertaking as a personal agreement among shareholders was enforceable between them. A shareholders' agreement cannot stop the company exercising a statutory power, but it can make the shareholder who votes for that exercise liable in damages.

Two drafting consequences follow. First, align the documents: if the agreement gives an investor a right to appoint a director, the articles must also permit that appointment. Second, use a priority clause stating which document prevails on each topic, with the parties obliged to vote to amend the articles to reflect the agreement.

The clauses that actually matter for Hong Kong SMEs

1. Share transfer restrictions and pre-emption

Section 134 of Cap. 622 states that a share is transferable in accordance with the articles. That gives the articles real power: with a right of first refusal, a shareholder cannot sell to an outsider without first offering the shares to the other members on the same terms.

Watch stamp duty. A transfer of Hong Kong stock attracts 0.13% on each side, 0.26% in total, plus a fixed fee under the Stamp Duty Ordinance (Cap. 117). A company should not register a transfer on an unstamped instrument.

2. Board control and reserved matters

The articles should set director appointment mechanics; the shareholders' agreement should list reserved matters needing investor or founder consent, such as issuing shares, borrowing above a threshold, changing the business, or disposing of material assets.

Note the statutory override on removal. Section 462 of Cap. 622 lets members remove a director by ordinary resolution on special notice, and section 548(6) excludes that resolution from the written resolution procedure. Articles that purport to entrench a director absolutely are of doubtful effect against the statute, though appointment rights and weighted voting can make removal practically difficult.

3. Deadlock and exit mechanics

A 50/50 company with no deadlock clause is a company waiting to fail. Workable mechanisms include a casting vote, escalation to mediation, a Russian roulette or Texas shoot-out buy-sell, or a compulsory buyout at fair value set by an independent accountant. Put valuation mechanics in the shareholders' agreement and procedural steps in the articles.

Without one, the remedies are blunt. Section 724 of Cap. 622 allows a member to petition the court where the company's affairs are conducted in a manner unfairly prejudicial, and section 725 gives wide powers including a purchase order. Section 177(1)(f) of the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32) permits winding up on just and equitable grounds, the route endorsed in Ebrahimi v Westbourne Galleries Ltd [1973] AC 360. Both are expensive and destroy value.

4. Founder vesting and leaver provisions

Hong Kong law does not imply vesting. A co-founder who leaves after eight months with 30% of the equity keeps it unless a document says otherwise. Vesting schedules, good leaver and bad leaver definitions, and a call option at a defined price belong in the shareholders' agreement, with a matching transfer restriction in the articles so the buyback can be implemented.

5. Dividends and information rights

Directors declare dividends unless the articles say otherwise. Minority investors usually want a stated dividend policy, monthly management accounts and inspection rights. Those belong in the shareholders' agreement, since publishing them in the articles would disclose them to competitors.

A realistic scenario

Two founders incorporate 50/50, adopt the model articles unamended and sign nothing else. Eighteen months later one wants to bring in an investor and the other refuses. There is no deadlock mechanism, and the refusing founder is not breaching any contract beyond the articles, which do not require him to consent or sell. The willing founder's options are negotiation, a section 724 petition, or a buyout on whatever terms can be agreed. In our experience advising Hong Kong companies since 2003, the clients who avoid this spend a little at incorporation on a shareholders' agreement that mirrors bespoke articles, then review both when an investor joins.

How to change your articles in Hong Kong

1. Check what the current articles permit, and whether any provision is entrenched or needs a higher majority.
2. Pass a special resolution with at least 75% of votes cast, at a general meeting or by written resolution where section 548 permits. Removing a director or auditor cannot be done by written resolution.
3. Deliver Form NAA1, Notice of Alteration of Company's Articles, within 15 days after the alteration takes effect, with a certified copy of the amended articles (s. 88(3)).
4. Update the shareholders' agreement so the documents do not diverge, and notify bankers where signing authority changes.

Late filing is an offence with a daily fine, and it surfaces during bank due diligence at the worst possible moment.

Key takeaways

• The articles are the public statutory constitution; a shareholders' agreement is a private contract.
• Section 86 of Cap. 622 makes the articles enforceable as a contract between the company and each member, and between members.
• Articles bind all future shareholders; a shareholders' agreement binds only signatories, and the company only if it is a party.
• Alteration needs a 75% special resolution under section 88, then Form NAA1 within 15 days.
• A shareholders' agreement cannot fetter a statutory power, but it can create enforceable personal obligations (Russell).
• Put transfer restrictions in the articles, and valuation, vesting and exit mechanics in the agreement.
• Without a deadlock clause, the fallback is a section 724 petition or a Cap. 32 section 177 winding-up petition.
