One of the main attractions of a limited company is limited liability, shareholders are generally not personally responsible for the company's debts. But this protection is not absolute. Here is a plain-English guide for England and Wales on when shareholders can be on the hook.
The general rule: limited liability
A company is a separate legal person from its owners (the principle in Salomon v Salomon). In a company limited by shares, a shareholder's liability is limited to the amount unpaid on their shares. So if you bought your shares and paid for them in full, you generally have no further liability for the company's debts, even if the company fails owing money. Creditors look to the company, not its shareholders.
When shareholders CAN be liable
There are important exceptions:
1. Unpaid or partly-paid shares
If your shares are not fully paid up, you remain liable to pay the outstanding amount if the company (or its liquidator) calls for it.
2. Personal guarantees
This is the most common route to personal liability. If a shareholder (often also a director) has given a personal guarantee (for a bank loan, lease or supplier credit) they are personally liable under that guarantee if the company defaults. Limited liability does not override a guarantee you signed.
3. Personal wrongdoing or fraud
A shareholder who personally commits a fraud or tort, or who is knowingly party to fraudulent trading, can be personally liable for their own wrongdoing, separate from their status as a shareholder.
4. "Piercing the corporate veil" (rare)
In very limited circumstances, a court may "pierce the corporate veil" and look behind the company, essentially where the company is used as a device to evade an existing legal obligation. The courts apply this narrowly (as confirmed in Prest v Petrodel), so it is the exception, not the rule.
5. Other situations
- Liability under specific statutory provisions in some contexts.
- Where a shareholder is also a director, they may face director-related liabilities (e.g. wrongful trading), but that arises from the director role, not from being a shareholder.
Practical points
- Think hard before signing a personal guarantee, it is the usual way shareholders/directors lose limited-liability protection. Negotiate caps and seek advice.
- Pay for your shares in full to avoid residual liability.
- Keep the company genuinely separate, proper records, no mixing of personal and company finances, no using the company to evade obligations.
Key takeaways
- Shareholders generally have limited liability, limited to any unpaid amount on their shares (Salomon principle).
- They can be personally liable for: unpaid/partly-paid shares, personal guarantees they have given, their own fraud/wrongdoing, and (rarely) where the court pierces the corporate veil.
- The personal guarantee is by far the most common route, sign with care.
- Keep the company genuinely separate and pay shares in full to preserve protection.
