The four types of business ownership
Topic 1.2 covers four types of ownership: sole trader (one owner), partnership (usually 2 to 20 partners), private limited company (Ltd, shares sold privately) and public limited company (plc, shares sold to the public). Sole traders and partnerships are unincorporated — owner and business are the same in law. Ltds and plcs are incorporated — a separate legal entity that owns assets and owes debts. Incorporation is the key divide: it decides limited or unlimited liability.
Limited vs unlimited liability
Liability for business debts is the most important consequence of the ownership type. Unlimited liability (sole trader, partnership): the owner is personally responsible for ALL business debts, so personal assets (savings, home) can be taken. Limited liability (Ltd, plc): owners can only lose the money they invested, because the incorporated company is a separate legal entity. Do not just name the term — explain whose money is at risk, and how much.
Size, finance and choosing a form
Ownership forms differ in size and in how easily they raise finance, and a business picks the form that fits its objectives. A sole trader is usually smallest, with finance limited to savings and small loans. A partnership can be larger as partners pool capital. An Ltd can be medium to large, raising finance by selling shares privately. A plc is typically largest, selling shares to the public but must publish accounts and risks takeover.

Definition, not description, on Define
On a Define question the examiner wants a precise meaning, not a loose description or example. Weak (often no mark): a private limited company is a family business with Ltd after its name. Secure: an incorporated business owned by shareholders whose shares are not sold to the public and whose owners have limited liability. Give the defining features, not an example.
June 2024 Paper 2, Q1(b): asked to define a form of ownership, most candidates gave a description of what it looks like rather than a definition, and very few gained the mark.
Limited liability: give the consequence
Candidates recognise limited liability as the right term but stop there. It does NOT mean the business cannot fail — the company can still go bankrupt. It means the owners (shareholders) can only lose the amount they invested; personal assets are protected. Develop the consequence: if the company fails they lose only what they put in, so their savings and home are safe.
November 2024 Paper 1, Q1(f): candidates knew the term "limited liability" but did not develop the consequence for the business or the owner, so lost the development marks.
Ltd shares are private, not public
A common slip is thinking anyone can buy shares in a private limited company. An Ltd sells its shares PRIVATELY — to family, friends or chosen investors — not on the open market. Only a public limited company (plc) sells shares to the general public on the stock exchange. This is why an Ltd keeps ownership within a chosen group, while a plc can raise much larger capital.
A sole trader need not work alone
Sole trader means one OWNER, not one worker. A sole trader owns and controls the business alone and has unlimited liability, but can still employ staff. Assuming a sole trader must work by themselves — or that hiring employees turns it into a partnership — is wrong. A partnership means shared OWNERSHIP (usually 2 to 20 partners), which is different.
Partnerships have unlimited liability
Do not assume every company-like firm has limited liability. Sole traders AND partnerships are unincorporated, so their owners have UNLIMITED liability — personal assets are at risk. Only incorporated firms (Ltd and plc) give limited liability. A frequent error is granting a partnership limited liability; owner count does not create incorporation.
A plc is not government-owned
The word "public" causes a recurring misconception. A public limited company (plc) is privately owned by its shareholders; it is called public only because its shares are sold to the general public on the stock exchange. It is NOT owned by the government. A public corporation is a different thing — a state-owned business owned by the government. Do not confuse the two.
November 2024 Paper 2, Q1(c): only about 60% correctly identified a public limited company, with others confusing it with a public corporation (a state-owned business).
Reach a supported judgement (AO4)
On a 9-mark Justify which option, choose ONE form and explain why it is better for THIS business. On a 12-mark Evaluate, weigh both sides and conclude why one outweighs the other. A no-decision answer stays in the middle band. Hooks: control versus protection, finance, privacy.
Build a chain, apply it to the firm
The AO2/AO3 marks come from advantages and disadvantages of each form APPLIED to the named business and developed as cause and effect — e.g. an Ltd gives limited liability, so the owners' savings are protected, so they invest to expand. A bare list with no chain stays low.
State/Outline need a case detail
On a State or Outline item about an ownership form, do not stop at a generic point — apply it to the named business with a specific detail from the extract. Naming the firm is not context. For example, link a sole trader keeping all the profit to the specific product they make.
| Type | Owners | Incorporated? | Liability | Typical size |

| Sole trader | one owner | No (unincorporated) | unlimited | smallest |
| Partnership | usually 2 to 20 partners | No (unincorporated) | unlimited | small to medium |
| Private limited company (Ltd) | shareholders (shares sold privately) | Yes (incorporated) | limited | medium to large |
| Public limited company (plc) | shareholders (shares sold to the public) | Yes (incorporated) | limited | largest |
