Sole Proprietorship
The business and the owner are legally the same person. If the business owes money, you owe money.

Business Structures
A supplier sues over a debt the business can't pay. In one version of the story, the owner loses only the business. In another, the owner loses the business, the car, and their personal savings. Same debt. Same amount. Different outcome. The difference was the type of business they chose to register years earlier.

Definition
The registration choice in that story is called a business structure. A business structure is the legal form you choose when you register a business. It sets the basic rules for who is responsible if the business owes money, how ownership can be shared, and whether the business can continue when an owner leaves.
The first question is simple: if the business cannot pay a debt, whose money and property are at risk?
The Golden Rule
The business structure you choose determines who pays when things go wrong.
Make the choice once, and it affects every debt, lawsuit, and financial problem that follows.

The Three Main Structures
Partnership
Two or more people own the business together. In many partnerships, each partner can become personally responsible for business debts.
Shared responsibilityLimited Company
The business is a separate legal person. It owns its assets and owes its own debts. In most cases, the owners risk only the money they invested.
Limited liability Important
Structure names, registration steps, taxes, and costs differ by country. This chapter explains the broad categories and trade-offs. Confirm the rules for your country with a qualified professional before registering. Volume 09: Legal Compliance covers the compliance side.

Compare the Three Structures
| Sole Proprietorship | Partnership | Limited Company | |
|---|---|---|---|
| Legally, the business is... | The owner, using a business name | The partners, under their agreement | A separate legal person |
| If the business owes money... | The owner is personally responsible | Partners are often personally responsible, even for a partner's mistake | The company owes the debt; owners usually risk their investment |
| Can it bring in an equity investor? | No. It does not issue shares. | Possible, but adding a partner changes the agreement | Yes. It can issue shares. |
| If an owner dies or leaves... | The business usually ends with the owner | It may end unless the agreement says otherwise | The company continues; ownership can pass to someone else |
| Setup and paperwork | Minimal | A written agreement is essential | Registration and ongoing filings |
| Usually best for | Testing a small one-person idea | Two or more people starting together | A business that needs to grow, borrow, take investment, or outlive its founders |
Remember This
More protection, easier ownership sharing, and stronger continuity usually bring more paperwork and cost. Choose the simplest structure that is still safe for the business you are building.

Example Story: The Same Debt, Three Outcomes
The same supplier sues over ₦4,000,000 that the business cannot pay. The debt is identical in each case. Only the structure changes.
World 1: Sole Proprietorship
What happensThe claim is against the owner. Business money is used first, then personal savings and other personal property can be at risk.
OutcomeThe business and the owner can fail together.
World 2: Partnership
What happensOne partner made the ordering mistake, but both partners can be pursued personally.
OutcomeA partner's decision can put every partner's personal money at risk.
World 3: Limited Company
What happensThe claim is against the company. Its machines, stock, and bank account are at risk.
OutcomeThe owner can lose the business without automatically losing personal savings or a car.
Same debt. Same amount. Three different outcomes, decided years earlier when the business was registered.

Why Investors Prefer Limited Companies
Investors need a clear legal way to own part of a business, put money into it, and transfer that ownership later. A sole proprietorship cannot issue shares, so there is nothing formal for an equity investor to buy.
- No shares to buy: saying "20% of the business" has no legal meaning in a sole proprietorship.
- Personal and business money are easily mixed: an investor cannot clearly see what belongs to the business.
- No continuity: the business may end when the owner dies or leaves.
A limited company solves these problems. It can issue shares, keep company money separate from personal money, and continue when ownership changes. That is why structure is an early part of every serious investment conversation.
Did You Know?
Being a separate legal person works both ways. A company can own property, sign contracts, sue, and be sued. It also means company money is not the owner's personal money. Treating company money as a personal pocket can remove the protection a company normally gives its owners.

Common Mistakes
Common Mistake #1: Staying Simple Long After It Stopped Being Safe
A sole proprietorship can be right for testing an idea. It may stop being safe once you have employees, serious debts, or personal property you cannot afford to lose. Choose the structure before something goes wrong, not after.
Common Mistake #2: An Unwritten Partnership
A partnership without a written agreement can feel easy until the first disagreement about profit, workload, an exit, or a debt. Put the rules in writing while everyone still agrees.
Common Mistake #3: Registering a Company, Then Ignoring Its Rules
Keep company money separate, keep required records, and complete filings on time. If owners ignore the company as a separate business, a court can ignore that separation too.
Common Mistake #4: Signing a Personal Guarantee Without Understanding It
A company loan may still become the owner's personal responsibility if the owner signs a personal guarantee. Read the guarantee before signing. Chapter 6, Section 6 explains this risk.

Quiz Yourself
Quiz 1
What does a business structure decide when the business cannot pay a debt?
It helps decide whether the owner, the partners, or the company itself is responsible for the debt.
Quiz 2
In an ordinary partnership, your partner signs a bad supply deal without telling you. Who can the supplier pursue?
Both partners can be personally responsible, even when only one partner made the decision.
Quiz 3
Why cannot a sole proprietorship take on an equity investor?
A sole proprietorship does not issue shares, so there is no formal ownership share for an equity investor to buy.
Quiz 4
Name two ways an owner can lose limited-liability protection.
Signing a personal guarantee, committing fraud, or treating company money as personal money can put the owner at risk.

Practice Exercise
- Write down your current structure. Do not assume. Check what is actually registered and whose name is on the bank account.
- If the business owed ₦4,000,000 tomorrow, what exactly of your personal money or property could be exposed?
- If you are in a partnership with no written agreement, list the five questions it must answer: profit split, workload, money rules, dispute resolution, and how a partner exits. Set a date this month to write it.
- If you plan to seek investment within two years, start the structure conversation now, not when an investor appears.
