The legal structure of an architectural firm isn't just administrative housekeeping — it determines who is personally on the hook if something goes wrong, how the business gets taxed, and how easily it can grow or be transferred. The exam tests your ability to match a firm's situation to the appropriate structure, so understanding the tradeoffs between each type is the real goal here.

The simplest structure is the sole proprietorship: one owner, minimal setup requirements, total management control. The advantages are flexibility and ease — you can be up and running with a business license and some stationery. The critical disadvantage is unlimited personal liability. If a client sues, everything is on the table: personal income, property, savings. The firm also lives and dies with its owner — it's difficult to sell and typically dissolves when the owner stops practicing.

Partnerships come in two flavors. In a general partnership, two or more people share management, profits, and risk — and each partner is personally liable for the actions and debts of the others. That last part matters: if your partner makes a catastrophic mistake on a project, your personal assets are exposed too. Partnerships are typically formed because each partner brings complementary skills — design ability, technical knowledge, business development — but the shared liability is a significant structural weakness.

A limited partnership introduces a second class of participant: limited partners who invest and receive profits but have no management role and are only liable up to the amount they've invested. General partners still carry full personal liability. In practice, limited partnerships have largely been replaced by the LLC, which offers similar flexibility with better liability protection for everyone involved.

Two other practical characteristics of partnerships worth knowing. First, dissolution: a general partnership is not a legal entity independent of its members — it's an agreement between specific individuals. When one partner withdraws, retires, or dies, the legal basis of the partnership is broken. A new agreement must be formed, which functionally creates a new partnership. Corporations and LLCs don't have this problem — they can survive ownership changes because they exist as entities separate from their members.

Second, taxation: both sole proprietorships and general partnerships are pass-through entities — income and losses flow directly to the owners' personal tax returns and are taxed at individual rates. The business itself pays no separate income tax. This is actually an advantage over C corporations, which face double taxation (more on that tomorrow). The tradeoff is that partners in a general partnership also pay self-employment tax on their share of the income, covering Social Security and Medicare contributions that an employer would otherwise handle.

The pattern to notice across all three of these structures: the less formal the organization, the more personal liability the participants carry. That tradeoff runs through all of business organization and will come up again when we get to corporations and LLCs.
