What this dot point is asking
SEAB wants you to compare the main legal forms a business can take and to evaluate which is right for a given firm. The decisions that flow from legal structure are liability (whose assets are at risk), finance (how easily capital can be raised), control (who runs it and who owns it), and continuity - so the choice of structure is a foundational strategic decision.
The answer
The unincorporated forms
Sole trader. One owner who is the business in law - it is unincorporated, so there is no legal separation between owner and business. Easy and cheap to set up, fully controlled by the owner, and private. The fatal drawback is unlimited liability: the owner is personally liable for all business debts, risking personal assets. Finance is limited to the owner's resources and borrowing.
Partnership. Two or more owners share capital, skills and workload, typically under a partnership agreement. More capital and expertise than a sole trader, but partners usually have unlimited liability (and are liable for each other's business actions), profits are shared, and disputes can arise. Suits professional practices and small ventures with several founders.
The incorporated forms
Incorporation creates a company that is a separate legal entity from its owners. This gives owners limited liability - they risk only the amount they invested - and gives the business continuity beyond its owners.
Private limited company (Pte Ltd / Ltd). Owned by shareholders whose shares cannot be sold to the general public. Offers limited liability, easier finance than a sole trader, and continuity, while keeping ownership within a controlled group (often family or founders). Costs: filing accounts, legal formalities, some loss of privacy.
Public limited company (PLC / listed company). Can sell shares to the general public, usually via a stock exchange listing. Can raise very large sums of capital and has high status and liquidity for shareholders. Costs: heavy regulation and disclosure, large flotation costs, loss of control as ownership disperses, the divorce of ownership and control (shareholders own, managers run), and pressure for short-term results.
The key concepts
- Incorporation gives the business its own legal personality, separate from owners.
- Limited liability caps owner risk at their investment - the single biggest advantage of incorporating, and what makes large external equity possible.
- Divorce of ownership and control - in large companies, the shareholders who own the firm are not the managers who run it, creating the principal-agent problem.
Evaluating the choice
The right structure trades off protection and finance against simplicity and control. A tiny, low-risk start-up may rationally stay a sole trader for simplicity; a growing firm taking on debt and risk benefits from incorporating for liability protection and finance; a firm needing very large capital and willing to accept dispersed ownership and regulation goes public. The decision tracks the firm's scale, risk, finance needs and the owner's appetite to share control.
Examples in context
Example 1. From founder garage to IPO. Many technology firms begin as a founder's sole venture or a small private company, incorporate early to protect founders and attract venture capital, then list on a stock exchange (an IPO) once they need very large capital to scale. Each step trades more access to finance against more disclosure and dispersed control - the legal-structure journey mapped onto a firm's growth, and a common pattern for Singapore and Southeast Asian startups listing on the SGX or abroad.
Example 2. A family business staying private. Many successful Asian family firms deliberately remain private limited companies rather than going public, accepting slower access to capital in exchange for keeping ownership and control within the family and avoiding the short-term pressure and disclosure of a listing. This shows that the "highest" structure is not always the goal; the choice reflects the owners' priorities on control and privacy.
Try this
Q1. State two advantages a sole trader has over a private limited company. [2 marks]
- Cue. A sole trader is cheaper and simpler to set up and run (minimal legal formality), keeps full control with the single owner, and enjoys greater privacy (no public filing of accounts).
Q2. Explain why a partnership might suit a firm of accountants better than a sole trader structure. [4 marks]
- Cue. A partnership pools the capital, expertise and client base of several professionals, spreads the workload and risk, and provides cover and continuity that a single owner cannot. For a knowledge-based professional practice, combining several qualified partners' skills and reputations is a clear advantage over one sole trader.
Q3. Analyse the main drawbacks a private company should weigh before deciding to become a public limited company. [6 marks]
- Cue. Going public brings large flotation costs, heavy regulation and disclosure requirements, loss of privacy, and dispersal of ownership that can dilute the founders' control and create a divorce of ownership and control with short-term market pressure. These must be weighed against the benefit of access to large-scale capital; flotation is worthwhile only if the firm genuinely needs that capital and can accept the loss of control and added scrutiny.

Original8 marksA successful sole trader running a chain of three cafes is considering converting the business into a private limited company. Discuss the case for and against making this change.Show worked answer →
Define the change. The owner would move from being a sole trader (unincorporated, with unlimited liability) to a private limited company (incorporated, a separate legal entity, with limited liability for shareholders).
Argue the case for. Limited liability protects the owner's personal assets if the business fails - increasingly valuable as the chain grows and takes on more debt and risk. Incorporation makes it easier to raise finance (selling shares to investors, easier bank borrowing), can confer status and continuity (the business survives the owner), and may bring tax advantages. With three cafes the scale now justifies these benefits.
Argue the case against. Incorporation brings administrative and compliance burdens (filing accounts, legal formalities, disclosure), some loss of privacy, and possible loss of full control if shares are sold to outside investors. Set-up and ongoing costs rise, and the owner must run the business more formally.
Evaluate with a judgement. For a growing three-cafe chain taking on more risk and possibly wanting outside investment, the protection of limited liability and easier finance usually outweigh the extra admin, so incorporation is likely sensible. The judgement strengthens if the owner plans further expansion or wants investors, and weakens if the business is staying small and the owner values total control and simplicity. A strong answer reaches a conditional conclusion tied to growth plans and risk.
Markers reward correct definitions, a balanced case for (liability, finance, continuity) and against (admin, control, cost), and a judgement conditioned on the firm's growth and risk.
Original6 marksExplain the meaning of limited liability, and analyse why it is important for a business seeking to raise large amounts of capital from investors.Show worked answer →
Explain limited liability. Limited liability means the owners (shareholders) of an incorporated company are liable for the company's debts only up to the amount they invested; their personal assets are protected if the company fails. This is possible because the company is a separate legal entity from its owners.
Analyse why it matters for raising capital. Investors are far more willing to put money into a business when their downside is capped at their investment rather than exposing all their personal wealth. This makes it possible to attract many shareholders and large sums - especially for a public limited company that sells shares widely - because the risk to each investor is bounded and the shares can be bought and sold. Without limited liability, raising large external equity would be very difficult, as few would risk unlimited personal exposure.
Markers reward a precise definition of limited liability resting on separate legal personality, and a developed link to why capped risk unlocks large-scale external investment.
