Articles of association are the founding legal document that creates a company as a separate legal entity, records its basic structure in the public register, and sets the ground rules for how it is owned and governed. Filing this document is what turns a business idea into a corporation that can own property, sign contracts, and shield its owners’ personal assets from company debts.
The name varies by country and by state. In the United Kingdom and most Commonwealth countries, every limited company must adopt articles of association, and the Companies Act 2006 provides a set of “model articles” that apply as default governance rules unless the company writes its own.1GOV.UK. Model Articles of Association for Limited Companies In the United States, the same formation document is usually called the articles of incorporation, though Delaware calls it a certificate of incorporation and Texas calls it a certificate of formation. When someone in a US context says “articles of association,” they almost always mean the articles of incorporation, and the two terms are treated interchangeably here.
One structural difference matters. In the UK, articles of association do double duty as both the formation document and the internal rulebook, covering everything from the company name to how the board meets. In the US, formation content sits in the articles filed with the state, and the day-to-day operating rules live in a separate internal document called the bylaws.
What Goes Into the Articles
Requirements vary by state, but a core set of provisions appears in almost every filing. Some are mandatory; leaving them out means the filing gets rejected. Others are optional but common because they customize the governance structure in ways that matter later.
Standard required provisions include:
- The corporation’s full legal name, typically including an identifier such as “Inc.,” “Corporation,” or “Company.”
- A registered agent — the person or company designated to receive legal documents on behalf of the corporation, with a physical street address in the state. A P.O. box does not qualify, and the agent must be available during normal business hours.
- Authorized shares: the number and classes of stock the corporation may issue, along with the rights attached to each class, such as voting rights for common stock or dividend preferences for preferred stock.
- The incorporator’s name and address. In many states, the incorporator’s role ends once the articles are filed and the initial board is seated.
- A business purpose. Most states accept a broad statement covering any lawful business activity, though a company can specify something narrower.
Common optional provisions include:
- Director liability limitation, capping or eliminating directors’ personal financial liability for certain breaches of duty. These clauses typically exclude intentional misconduct and bad-faith conduct.
- Indemnification, requiring the company to reimburse directors and officers for legal costs tied to their corporate roles when they acted in good faith. Some indemnification clauses include “advancement,” meaning the company pays legal expenses as they arise rather than at the end of the case.
- Duration. Corporate existence is perpetual by default in every state, but the articles can set an end date.
- Preemptive rights, guaranteeing existing shareholders the chance to buy a proportional share of any new stock issuance before outsiders can.
- Supermajority voting requirements for specific corporate actions, raising the threshold above the default majority.
Liability limitation and indemnification are technically optional, but nearly every corporation of any size adopts them. Without those provisions, directors face personal exposure every time a business judgment goes wrong, and recruiting qualified board members becomes difficult.
How the Articles Create Limited Liability
Filing the articles does more than register a name. It creates a legal entity separate from the people who own it. The corporation owns its assets and owes its debts. A shareholder’s financial exposure is limited to what they invested. A creditor of the corporation cannot, in the ordinary case, reach a shareholder’s personal bank account or home.
That protection is the whole reason most people incorporate, and it depends on maintaining a real separation between the owners and the entity. Courts can “pierce the corporate veil” and hold owners personally liable when the separation collapses. Common triggers include:
- Commingling funds — using the corporate account for personal expenses, or the reverse.
- Undercapitalization — failing to fund the company well enough to meet its reasonably expected obligations.
- Ignoring formalities — no board or shareholder meetings, no minutes, no issued stock. Treating the corporation as if it doesn’t exist invites a court to agree.
- Using the corporate form to deceive creditors or evade obligations.
Well-drafted articles are only the first step. The liability shield holds up because the corporation actually follows its own governance documents. Pristine articles paired with a company that never holds a board meeting hand future plaintiffs the evidence they need.
Articles, Bylaws, and Shareholders’ Agreements
A typical corporation runs on three governance documents, and they follow a strict hierarchy when they conflict.
The articles sit at the top. They’re filed with the state, they’re public, and they control. Any bylaw provision that contradicts the articles is unenforceable. That’s why fundamental structural decisions — share classes, director liability limits, supermajority voting requirements — belong in the articles rather than the bylaws. Putting them in the articles also means they cannot be quietly changed by the board alone.
Bylaws are internal documents adopted by the board after the articles are filed. They cover operational detail: how meetings are called and noticed, what constitutes a quorum, what officers the company will have, how directors are elected and removed, and how dividends are approved. Most states require a corporation to have bylaws but do not require them to be filed publicly. Bylaws can generally be amended by the board without a shareholder vote, though the articles can restrict that power.
A shareholders’ agreement is a private contract among some or all of the shareholders. It can address voting arrangements, restrictions on share transfers, rights of first refusal, buyout procedures on death or departure, and dispute resolution. In closely held companies, these agreements often carry as much practical weight as the formal corporate documents, and because they are private contracts rather than filed governance instruments, they offer flexibility the articles cannot.
Amending the Articles
Changing the articles follows a formal process designed to keep the board from acting alone. The directors first adopt a resolution proposing the specific amendment, then submit it to a shareholder vote. Under default rules in most states, approval requires a majority of the outstanding shares entitled to vote. The articles themselves can impose a higher threshold for certain kinds of amendments.
Once shareholders approve, the company files articles of amendment (sometimes called a certificate of amendment or restated articles) with the Secretary of State. The change takes legal effect when the state accepts the filing. State filing fees for amendments are modest, typically in the range of $30 to $60, though they vary by state.
Common reasons to amend include increasing the authorized shares before a fundraising round, changing the company name, adding or modifying a class of preferred stock, and updating director liability provisions. Some amendments are administrative housekeeping. Others, especially those that dilute shareholders or alter voting rights, can trigger serious debate and may require class-specific voting if the articles or state law mandate it.
Filing Costs and the Cost of Falling Out of Compliance
State filing fees for initial articles run from roughly $50 to $500 or more, depending on the state. Some states charge a flat fee; others tie the fee to the number of authorized shares or stated capital. These are government fees only. They do not include attorney’s fees to draft the articles or the ongoing cost of a commercial registered agent service.
The more expensive risk arrives later. If a corporation lets its status lapse by missing annual fees or required reports, the liability shield can disappear, and owners who assumed they were protected may end up personally responsible for company debts. Most incorporations do not go wrong at the filing stage; they go wrong years later when annual compliance slips. Reinstating a lapsed corporation is almost always possible by filing back paperwork and paying overdue fees with penalties, but the gap when the corporation was inactive creates real exposure. Filing correctly the first time and staying current with whatever annual maintenance the state requires is far cheaper than fixing the problem after a creditor finds it.
