Member Liability in a Company Limited by Guarantee vs. Shares

Both structures limit member liability, but they use different measures. One is tied to shares; the other is tied to a guarantee contribution on winding up.

Company limited by shares

A member holds shares and usually risks the amount paid or remaining unpaid on those shares. If the shares are fully paid, the member generally has no further liability solely because the company owes debts, subject to exceptions under law such as personal guarantees or misconduct.

Company limited by guarantee

A guarantee company has members who promise to contribute a stated amount to the company's assets if it is wound up while they are members or within the relevant statutory period. The articles state each member's guarantee. Many non-profit or membership organizations use this structure because it does not issue share capital.

Compare the liability measures

• Shares: unpaid share amount is the usual limit for a member's liability.
• Guarantee: the promised contribution amount is the usual limit on winding up.
• Neither structure makes directors, guarantors or persons committing their own wrongful acts immune from separate liability.
• The company's constitution and Companies Ordinance determine the details.

Two different ways to measure a member’s exposure

A company limited by shares measures a member’s liability by the amount, if any, unpaid on the shares held. If the shares are fully paid, the member generally has no further contribution obligation merely because the company owes creditors money. If shares are partly paid, the unpaid amount can be called under the applicable law and company arrangements. The member’s investment may lose value, but that economic loss is different from unlimited personal liability for company debts.

The guarantee model

A company limited by guarantee has no share capital in the ordinary sense. Each member undertakes to contribute a specified amount if the company is wound up while that person is a member, or within the statutory period after membership ends, for payment of debts and winding-up expenses. The amount is the guarantee stated in the company’s articles, not the company’s total liabilities. It is contingent until the winding-up contribution is called in the statutory context.

Example: compare the possible call

Suppose A holds 1,000 shares with HK$10 nominal value, of which HK$6 per share is unpaid. A’s potential share liability is tied to the HK$6,000 unpaid amount, subject to the relevant facts and law. B belongs to a guarantee company whose articles state a HK$500 guarantee. If the company is wound up and the statutory conditions are met, B’s contribution is capped by the guaranteed amount; it does not become a pro rata share of every company debt. These figures illustrate the structure, not a substitute for checking the articles or capital terms.

What limited liability does not do

Limited liability is not immunity from a member’s own obligations. A person may separately owe money under a personal guarantee, an unpaid subscription, a contract, a statutory liability, or conduct giving rise to personal liability. Fraud, wrongful conduct, or misuse of the corporate form can raise separate legal issues. The company remains liable for its debts; the point is that member contribution is limited according to the company type and applicable rules. Do not turn the usual rule into an absolute statement that an owner can never be pursued.

How to answer a company-type question

Identify whether the facts describe shares or a guarantee. For a share company, ask whether the shares are fully paid and what amount remains unpaid. For a guarantee company, find the amount in the articles and the timing of membership relative to winding up. Then distinguish that member contribution from any separate personal undertaking. In a short exam question, “limited by shares” maps to unpaid share capital; “limited by guarantee” maps to the promised contribution on winding up.

When contribution becomes payable

For shares, liability tracks the issue terms and unpaid capital, subject to the applicable call process. For a guarantee company, the undertaking matters in winding up and is capped by the member’s stated guarantee. Timing and collection occur under the statutory insolvency framework. Do not assume a creditor can collect the guarantee as an ordinary personal debt from the day the company borrowed.

Membership changes matter

The Ordinance can cover a person who ceased membership within a prescribed period before winding up, subject to conditions. Someone joining after a debt was incurred is not automatically liable for that debt beyond the applicable contribution. Track resignation, transfer and winding-up dates; a company’s label alone does not resolve every liability question.

Separate legal personality remains

Both forms are separate legal persons. Creditors ordinarily claim against the company and its assets, while member exposure follows contribution rules and any separate undertaking. Guarantee companies are common in membership or non-profit settings, but purpose does not define liability. The incorporation form, articles and statute do.

Reading the constitutional documents

A company’s articles and share terms help determine the exact unpaid amount or guarantee promise. Confirm whether shares are fully paid, whether calls are outstanding, and the stated guarantee for the relevant member. Where facts are incomplete, explain the general rule and identify what document would resolve the amount instead of inventing a figure.

Exam contrast in one sentence

For a share company, member contribution follows the unpaid amount on the shares; for a guarantee company, it follows the promised amount payable in the winding-up circumstances set by statute. In either case, a separate personal guarantee or independent wrongdoing can create a different liability.

Exam takeaway

A share company limits liability by unpaid share capital; a guarantee company limits it by the member's promised contribution on winding up. Identify the company's form before stating the member's exposure.
