The honest answer is that directors have more power, and most shareholders have no idea that's the default. A shareholder agreement can change this. Without one, or with a poorly drafted one, you are funding a company you do not actually control.
This is not a theoretical problem. It shows up when a founder gets pushed out of their own company. It shows up when an investor watches the board approve a transaction that destroys their preferred position. It shows up in the gap between what someone thought they owned and what the law says they can actually do.
The Default Answer Is "Directors," and That Should Concern You
Corporate law in every major U.S. jurisdiction hands operational authority to the board of directors, not to shareholders. In Delaware, which governs the majority of venture-backed and closely held corporations in this country, that principle is codified in DGCL § 141(a): the business and affairs of a corporation shall be managed by or under the direction of a board of directors. That sentence is doing a lot of work, and most shareholders have never read it.
What this means in practice is that the people you elect to the board, once elected, are not your agents. They owe fiduciary duties to the corporation and to shareholders broadly, but they are not obligated to do what any individual shareholder wants. They can approve executive compensation, authorize debt, enter into contracts, and in many cases pursue strategic transactions, all without coming back to shareholders for a vote.
Shareholders do retain certain rights that cannot be stripped away without their consent. They vote on the election of directors, on amendments to the certificate of incorporation, and on fundamental transactions like mergers or asset sales above a certain threshold. In California, Corporations Code § 1201 requires shareholder approval for a reorganization where the acquiring entity will issue shares exceeding certain thresholds. These are meaningful rights. They are also limited ones.
The error most founders and early investors make is assuming that owning equity means owning control. It does not. Equity is an economic interest. Control is a structural question, and structure is determined by your governing documents. If your certificate of incorporation and your shareholder agreement do not explicitly reserve certain powers for shareholders, those powers belong to the board.
The gap between what you think you own and what you can legally enforce is where most corporate disputes begin. By the time the dispute is visible, the documents have already decided who wins.
A Shareholder Agreement Is How Shareholders Take Power Back
A shareholder agreement is not a formality. It is the document where shareholders negotiate the terms on which they will participate in a company, and where the balance of power is either locked in or left to chance. If you signed one without reading it carefully, or if your company has been operating without one, the board currently has more authority than you may realize.
The most powerful provisions in a well-drafted shareholder agreement are the ones that require shareholder consent before the board can act. These are called protective provisions, reserved matters, or consent rights depending on the drafting tradition, and they function as a veto. Before the board can issue new equity, take on debt above a specified threshold, sell material assets, or change the company's business, they must obtain approval from a defined class of shareholders. Without this language, none of those actions require your sign-off.
Drag-along and tag-along rights are the other provisions that determine real-world power in a liquidity event. A drag-along clause allows a majority shareholder or investor class to compel other shareholders to sell their shares on the same terms in an acquisition. A tag-along clause gives minority shareholders the right to join a sale on the same terms rather than being left behind. Neither right exists by default. Both must be negotiated and documented.
Preemptive rights are similarly non-default in most jurisdictions. Without a preemptive rights provision in your shareholder agreement, the board can authorize a new round of equity that dilutes your ownership, and you have no legal right to maintain your percentage. This is not a hypothetical. It is a standard mechanism by which early shareholders, including founders, get diluted out of meaningful ownership over successive financing rounds.
The economic terms matter as much as the governance terms. Liquidation preferences, anti-dilution protections, and dividend rights all live in the shareholder agreement or in the certificate of incorporation, and they determine who actually gets paid, and in what order, when the company exits. A shareholder who owns 20% of a company on paper may receive nothing in an acquisition if the liquidation stack is structured against them.
Delaware Just Made This More Complicated (and More Useful)
Delaware amended its General Corporation Law in 2024 in a way that most shareholders and founders have not yet absorbed. The Moelis decision, decided by the Delaware Court of Chancery before the amendment, held that certain provisions in stockholder agreements violated DGCL § 141 because they impermissibly constrained the board's authority. The decision created significant uncertainty about how far a shareholder agreement could go in restricting what a board could do.
The legislature responded. Effective August 1, 2024, DGCL § 122(18) now expressly permits corporations to enter into contracts that restrict or condition the exercise of corporate powers, require prior consent before specified actions are taken, or covenant that certain acts will or will not occur. This is a meaningful statutory authorization. It means that the protective provisions and consent rights that sophisticated investors have been negotiating for years are now on firmer legal footing in Delaware, provided the agreement is properly structured.
The Delaware Supreme Court added another layer in January 2026, holding that a facial challenge to a voidable corporate act accrues when the act is taken, and that laches may bar later challenges. The practical implication is that if your shareholder agreement contains a provision that could be characterized as voidable rather than void, and someone waits too long to challenge it, the challenge may fail on timeliness grounds alone. This is a distinction that matters at the drafting stage. A provision that is void is unenforceable from the beginning. A provision that is merely voidable can be ratified, waived, or time-barred. Your attorney needs to know which category your agreement's provisions fall into.
The lesson from recent Delaware jurisprudence is that the shareholder agreement you signed two years ago may be operating in a different legal environment than the one it was drafted for. This is not a reason to panic. It is a reason to review. The law has moved, and agreements that were adequate in 2022 may have provisions that are either more enforceable or more vulnerable than their drafters intended.
If your company is incorporated in California rather than Delaware, the analysis is different but the stakes are identical. California's General Corporation Law does not have the same express authorization that DGCL § 122(18) now provides, which means the enforceability of certain board-restricting provisions depends more heavily on how they are structured and what the agreement says about remedies.
When the Agreement Fails, the Board Wins
The most dangerous shareholder agreement is the one that looks complete but leaves the critical moments unaddressed. Founders negotiate hard on valuation and dilution and then accept boilerplate language on governance. Investors focus on their liquidation preference and skip past the consent rights section. The document gets signed, everyone moves on, and the gaps stay invisible until the moment they matter most.
A consent right that covers "material transactions" but does not define materiality is not a consent right. It is an invitation to litigation over what the word means when the board has already approved something you believe required your vote. A drag-along provision that does not specify the required majority, the conditions of the drag, or the minimum price threshold gives the majority shareholder enormous latitude to compel a sale on terms that benefit them and harm you.
The board-shareholder power dynamic also shifts over time in ways that shareholders do not anticipate. As a company raises successive rounds of financing, new investors negotiate their own consent rights, and the governance structure becomes layered. A Series A investor may have veto rights over certain actions. A Series B investor may have different, overlapping rights. The shareholder agreement that governed the company at founding may have been superseded, amended, or restated in ways that reduced the original shareholders' protections without their full understanding of what they were signing away.
This is not a situation where you read the agreement once at closing and set it aside. The shareholder agreement is a living document in the sense that its provisions interact with everything the company does afterward. When the board takes an action, the first question is whether the shareholder agreement required consent. If it did, and consent was not obtained, the question becomes whether the act is void or voidable, and whether anyone with standing will challenge it in time.
By the time that question is live, you are already in a dispute. The time to address it is before the agreement is signed, or during a review while the company is still operating without a crisis.
Shareholder agreements are where power is either secured or surrendered, and this is not a document you should draft, review, or sign without an attorney who practices in this area specifically.
If you are ready to have your existing shareholder agreement reviewed, draft one for a new entity, or understand what rights you actually hold before the next financing round closes, book a paid intake with Delina. This is not a free call. It is a focused, strategic session with an attorney who has read everything above and has specific opinions about your situation.
