The Simplest Structure There Is

A sole proprietorship is a business owned and run by one person, with no legal separation between the owner and the business. No separate legal entity exists — the business simply is the person, in the eyes of the law.

How It's Formed

(REGION-SPECIFIC RULE: laws vary by country.) In many places, no formal paperwork is required — if someone starts doing business under their own name with no other structure, they're automatically a sole proprietor. A local license or a "doing business as" filing may still apply.

The Real Risk: Ask Yourself This

If this business gets sued, or can't pay a debt, whose money is on the line? Because there's no legal separation between the person and the business, the answer is: the owner's personal bank account, car, potentially their home. That's the single biggest trade-off of this structure — and exactly why later lessons introduce LLCs and corporations, built specifically to change that answer.

Worked Example

A freelance photographer books clients under her own name — no LLC, no paperwork beyond a basic license. She's a sole proprietor by default. Now imagine her equipment fails and damages a client's property. Ask yourself: whose assets could a lawsuit reach? Because there's no separation, it's hers personally — not just "the business's."
