Articles of Incorporation vs. Corporate Bylaws

What Articles of Incorporation Cover

Articles of incorporation, sometimes called a certificate of incorporation, are the document that creates a corporation as a legal entity. A corporation's founders, usually called incorporators, file this document with the state's filing agency, typically the Secretary of State or a Division of Corporations, along with a filing fee. State corporation statutes generally require the articles to state the corporation's name, its registered agent and registered office address, the number of shares it's authorized to issue, and the name and address of each incorporator. Because articles of incorporation are filed with a state agency, they become part of the public record, and anyone can typically request a copy or look up the filing through the state's business entity search.

What Bylaws Cover

Bylaws are the corporation's internal rulebook, adopted by the initial board of directors, usually at the organizational meeting held right after the articles are filed. Bylaws typically cover how and when shareholder and board meetings are called and noticed, how many directors sit on the board and how they're elected, what officer positions exist and what each one does, how voting and quorum requirements work, and how the bylaws themselves can later be amended. Unlike articles of incorporation, bylaws are a private document: no state corporation statute requires a corporation to file its bylaws with any state agency, and they aren't part of the public record the way articles of incorporation are.

Why the Split Exists

The two-document structure separates the facts a state needs to track publicly, like who can be sued and served with legal papers, from the day-to-day operating rules that are the corporation's own business. Keeping bylaws private also gives a corporation flexibility: it can adjust its internal governance, such as adding a board seat or changing when the annual meeting happens, without paying a state filing fee or waiting on a state agency to process an amendment.

How Each Document Gets Changed

Changing articles of incorporation requires filing a certificate or articles of amendment with the state's filing agency, along with a fee, and the change generally isn't effective until the state processes it. Changing bylaws is an internal matter: the board, or in some cases the shareholders, votes to amend the bylaws according to whatever amendment procedure the bylaws themselves set out, and the change takes effect once that internal vote passes, with no need to file anything with the state. Most bylaws allow the board to amend them by a simple majority vote unless the bylaws specifically reserve a particular section for shareholder approval only.

Where to Find a Sample of Each

A state's own filing agency website typically publishes the required form or a checklist of required contents for articles of incorporation, since the state needs the document filed in a format it can process. Bylaws have no standard state-issued form, since they're an internal document; many attorneys and corporate service providers maintain their own bylaw templates that a corporation customizes to its own board size, officer structure, and voting rules.

What Happens If There's a Conflict Between the Two

If a corporation's bylaws conflict with its articles of incorporation, the articles generally control, since the articles are the more fundamental document that created the corporation and state corporation statutes generally require bylaws not to conflict with the articles. A common source of conflict is authorized shares: if the bylaws describe a share structure that doesn't match what the articles actually authorize, the articles' authorized share count is what's legally in effect, and the bylaws would need to be corrected.

Keeping Both With Your Corporate Records

Even though only articles of incorporation are filed with the state, a corporation should keep both documents, along with its stock ledger, meeting minutes, and resolutions, together in its corporate records book. A bank, a lender, a potential buyer, or an investor doing diligence will often ask to see both the filed articles and the current bylaws, so keeping an up-to-date copy of each on hand, including every amendment, saves time when either is requested.

Check Your Specific State's Exact Requirements

What must appear in articles of incorporation, and how detailed the bylaws need to be, varies by state corporation statute. Before filing, check your state's filing agency instructions for the current required contents of articles of incorporation, since some states ask for more detail than others, such as the corporation's specific business purpose.

Don't Treat Bylaws as a Formality to Skip

Because bylaws aren't filed anywhere, it's tempting to skip adopting them or to use a generic template without reviewing it. But most state corporation statutes still require a corporation to have bylaws, and a bank, investor, or court looking at whether the corporation observed basic formalities will expect to see them. Adopt bylaws that actually match how your corporation operates, such as the real number of directors and the real officer titles you use.

Amendments Should Be Documented Either Way

Even though bylaw amendments don't require a state filing, document each one in writing and keep it with your corporate records, the same way you would document a resolution. A board that changes its bylaws informally, without a written amendment on file, can create confusion later about which version of the bylaws actually governs a given decision.

This Is Not Legal Advice

The exact contents required in articles of incorporation, and what a corporation's bylaws must or can't say, depend on your state's specific corporation statute and your corporation's own structure. Talk to a business attorney when drafting or amending either document, particularly before a financing round, merger, or any change that affects shareholder rights.

Review Both Documents When Your Business Changes

A corporation that adds a new class of stock, moves its principal office, or changes how many directors sit on the board often needs to update both documents: the articles if authorized shares or the registered agent change, and the bylaws if the board size, officer titles, or meeting procedures change. Reviewing both together when a major change happens, rather than updating only the one that technically requires a state filing, keeps the two documents from drifting out of sync with how the corporation actually operates and with each other.
