Company constitution documents are the paired legal instruments that bring a business entity into existence and set the rules for how it runs. For a corporation, that pair is the articles of incorporation and the bylaws. For an LLC, it’s the articles of organization and the operating agreement. One document is filed publicly with the state to create the entity; the other stays internal and governs decision-making, ownership, and disputes among the people who run and own the company. Getting both right at formation is what preserves the limited liability shield you incorporated to obtain, because courts can hold owners personally liable when a company ignores its own governing documents.
The Formation Document
The formation document is what gives your company legal existence. You file it with the Secretary of State (or equivalent agency), pay a fee, and the state issues a certificate confirming the entity exists. Corporations file articles of incorporation, called a certificate of incorporation in some states. LLCs file articles of organization. Both serve the same function: they register the entity and establish its fundamental characteristics on the public record.
A corporation’s articles of incorporation typically include:
- The company name, which must be distinguishable from names already registered in the state
- The registered agent’s name and physical street address (not a P.O. box)
- The number and types of shares the corporation is authorized to issue
- A statement of purpose describing the business activities the entity may pursue
An LLC’s articles of organization are shorter. Most states ask for the company name, the registered agent’s name and address, a principal office address, and whether the LLC will be managed by its members or by designated managers. Detailed purpose statements and capital structure aren’t usually required in the LLC’s formation filing.
Filing fees vary widely by state, from as low as $35 to $500 or more. A handful of states calculate the fee based on the number of authorized shares or stated capital, which can push corporate filings well above the typical range. Most Secretary of State offices accept filings online, by mail, or in person.1U.S. Small Business Administration. Choose Your Business Name
The Internal Governance Document
If the formation document is the birth certificate, the governance document is the rulebook. Corporations use bylaws. LLCs use operating agreements. Neither is filed with the state, but both are legally binding on the people who own and run the company.
Corporate Bylaws
Bylaws cover the mechanics of running the corporation. Standard provisions include:
- How directors are elected, removed, and replaced
- How often the board meets and what constitutes a quorum
- How officers are appointed and what authority each one holds
- Voting procedures and notice requirements for shareholder meetings
- How shares can be transferred
- The process for amending the bylaws themselves
A quorum provision deserves careful thought. A quorum is the minimum number of voting members who must be present before official action can be taken. Set it too high and routine meetings stall; set it too low and a small faction can push through decisions. Without a specific provision, most states default to a simple majority, and any vote taken without a quorum is void.
LLC Operating Agreements
An operating agreement performs a similar role but reflects the LLC’s different ownership structure. Instead of shareholders and directors, you’re dealing with members and managers. The agreement defines:
- Each member’s ownership percentage and capital contribution
- How profits and losses are divided (which can differ from ownership percentages if the agreement says so)
- Who has authority to sign contracts or take on debt
- What vote threshold is required for major decisions
- What happens when a member wants to leave, dies, or sells their interest
If you don’t adopt a written operating agreement, default state rules fill the gaps in many states, and those defaults may not match what you and your co-owners actually intended.
Capital Structure and Decision-Making Rules
Two decisions come up in every formation and deserve close attention.
Capital structure. A corporation’s articles must state how many shares are authorized. If you want different classes of stock, such as preferred shares with priority dividend rights and common shares with voting rights, you define those classes in the articles. One tax consequence to keep in mind: if you plan to elect S corporation status, your governing documents can only provide for a single class of stock, and any provision giving some shares different distribution or liquidation rights will disqualify the election.2Internal Revenue Service. S Corporations LLCs handle this differently; the operating agreement specifies each member’s capital contribution and ownership percentage, and profit and loss allocations can follow a separate formula.
Decision thresholds. Your bylaws or operating agreement should answer every predictable governance question. Who signs contracts? How are major decisions like selling company assets or taking on significant debt approved? What vote is required? Default corporate statutes generally require a simple majority for routine matters, but many companies set higher thresholds (two-thirds or unanimous consent) for actions that could fundamentally change the business.
Supplementary Governance Agreements
Beyond the two core documents, many companies adopt additional agreements that fill gaps.
Shareholder and member agreements are private contracts between owners that handle succession planning, buyout triggers (death, divorce, disability), transfer restrictions, and formulas for valuing an owner’s interest. If a shareholder agreement conflicts with the bylaws, the agreement should include a priority clause specifying which document controls.
Conflict of interest policies require directors and officers to disclose any personal financial interest in a transaction the company is considering. The conflicted person abstains from the vote, and the board documents the disclosure and outcome in the minutes. That paper trail matters if the transaction is challenged.
Indemnification agreements protect directors and officers from personal liability for decisions made in good faith while serving the company, covering legal defense costs and settlements within the limits state law allows.
None of these are filed with the state. They’re internal contracts, but courts enforce them, and their absence can create expensive ambiguity when relationships between owners deteriorate.
Extra Requirements for 501(c)(3) Nonprofits
If you’re forming a nonprofit corporation that will seek tax-exempt status under Section 501(c)(3), the IRS imposes requirements on your articles of incorporation that go beyond state law. The articles must contain:
- A purpose clause stating the organization is formed exclusively for charitable, religious, educational, or scientific purposes
- A dissolution clause directing that remaining assets go to another tax-exempt organization or a government entity if the organization shuts down
- A prohibition on private inurement, stating that no part of the organization’s earnings can benefit any private individual
- A restriction barring participation in political campaigns for or against candidates for public office
The IRS publishes suggested language for each clause. Deviating from it without good reason is one of the most common reasons applications for tax-exempt status get delayed or denied.3Internal Revenue Service. Suggested Language for Corporations and Associations per Publication 557
Adopting and Storing the Documents
Formation documents take effect when the state accepts the filing. Governance documents take effect when they’re formally adopted by the people who control the company at its inception.
For corporations, adoption happens at an organizational meeting held after the articles of incorporation are filed. The incorporators or initial directors adopt the bylaws, elect the first board (if incorporators are meeting), appoint officers, and authorize the first stock issuances. A resolution approving the bylaws is recorded in the minutes. If there’s only one incorporator or director, many states allow these actions by written consent instead of a formal meeting.
LLC members typically adopt the operating agreement by signing it, often at the same time they file the articles of organization. There’s usually no statutory requirement for a formal meeting, though documenting the adoption in writing matters if the agreement’s validity is later questioned. Signatures can be traditional or electronic depending on the state, and a few states still require notarization for certain formation documents.
Storage matters more than most owners realize. The formation document becomes a public record anyone can look up. Bylaws and operating agreements stay internal, but you should keep signed originals at the principal or registered office, along with meeting minutes, resolutions, and amendments. Corporate shareholders have a statutory right in virtually every state to inspect company records, including bylaws and minutes, during business hours after providing written notice. That right cannot be eliminated by the bylaws or articles.
Amending the Documents
Governing documents aren’t permanent. The amendment process depends on which document you’re changing.
Amending the articles of incorporation takes two steps. The board first adopts a resolution proposing the change and recommending it to shareholders. Shareholders then vote, with most states requiring at least a majority of all shares entitled to vote. After approval, the company files articles of amendment with the Secretary of State and pays a filing fee. Common reasons include changing the company name, increasing authorized shares, or adding new share classes.
Bylaw amendments don’t require a state filing. Most bylaws grant the board authority to amend them, though the bylaws may require a supermajority or shareholder approval for changes to certain protected provisions. Follow whatever procedure the current bylaws prescribe; skipping steps or ignoring notice requirements can render the amendment invalid.
Operating agreement amendments typically require the consent of a majority or supermajority of members, depending on the existing agreement. Some provisions, such as changes to profit-sharing ratios, may require unanimous consent. Whatever the threshold, document the approval in writing and have all consenting members sign the amended agreement.
What Happens If You Ignore the Documents
Filing your governing documents is the beginning of compliance, not the end. Two serious risks follow when owners treat these documents as paperwork rather than rules.
Piercing the corporate veil. The point of incorporating or forming an LLC is to separate personal assets from business liabilities. Courts can disregard that separation when owners treat the company as an extension of themselves. Evidence supporting veil piercing includes mixing personal and business funds, failing to hold required meetings, not keeping minutes, and ignoring procedures spelled out in the bylaws or operating agreement. Failure to observe formalities alone may not be enough to lose liability protection, but it’s regularly used as evidence that no real separation exists between owner and entity.
Administrative dissolution. States can involuntarily dissolve a company for missing annual reports, failing to pay franchise taxes, or not maintaining a valid registered agent. Once dissolved, the company loses legal authority to conduct business. Directors or officers who keep operating can face personal liability for debts incurred during that period. Most states allow reinstatement, but it requires filing all delinquent reports, paying back fees and penalties, and sometimes re-registering the business name if someone else claimed it.
Beyond state filings, the governing documents themselves create internal obligations. If your bylaws require an annual shareholder meeting, hold one. If the operating agreement requires written consent before admitting a new member, get written consent. Treating those provisions as optional defeats the purpose of having them and produces exactly the kind of evidence that makes veil piercing possible.
