What Is Unlimited vs Limited Liability?

Unlimited liability means a business owner is personally responsible for business debts. Limited liability means an owner is not normally personally responsible for debts beyond the amount they have invested in the business, or still owe on their shares.

How it works

A sole trader has unlimited liability because the owner and the business are not separate legal entities. If the business cannot pay its debts, creditors may be able to claim against the owner's personal assets. Partners in an ordinary partnership generally have unlimited liability too.

A limited company is a separate legal entity: it can own assets and owe debts in its own name. Its shareholders have limited liability. They may lose the money they invested if the company fails, but creditors cannot normally make them pay the company's remaining debts from their personal assets. This is different from an ordinary partnership; a limited liability partnership also offers its members limited liability.

Worked example

Suppose a business owes creditors £20,000\pounds 20{,}000£20,000 but has only £5,000\pounds 5{,}000£5,000 in business assets. A sole trader may have to cover the remaining £15,000\pounds 15{,}000£15,000 personally. If the business is a limited company, its shareholders are not normally required to cover that shortfall personally, although they could lose their investment.

Limited liability is not an absolute guarantee: an owner who has personally guaranteed a loan may still have to repay it. A personal guarantee is a promise to pay if the business cannot.

Exam mistake to avoid: Do not say that limited liability means the business does not have to pay its debts. The distinction is whether its owners are personally liable for them. This matters to creditors, who may have less access to an owner's personal assets when lending to a limited company.
