Corporate Powers: Express, Implied, and Ultra Vires Doctrine

Corporate powers fall into three related concepts: express powers granted by statute and the articles of incorporation, implied powers that flow from the practical needs of running the business, and the ultra vires doctrine that governs what happens when a corporation acts beyond both. Express powers are the specific authorities the law and the charter spell out. Implied powers cover everything reasonably necessary or convenient to carry those out. Ultra vires once let courts void unauthorized acts entirely, but modern statutes have narrowed that remedy to a handful of proceedings while leaving the underlying transactions enforceable.

Where a Corporation’s Authority Comes From

Authority begins with the state statute of incorporation. Thirty-six jurisdictions have adopted the Model Business Corporation Act in whole or in part, making it the most common framework in the United States. The MBCA supplies default rules, and individual states modify them to fit local policy.

The articles of incorporation are the founding document, filed with the state’s business entity office and available as a public record. They set the corporation’s name, its registered agent, the authorized shares, and, if the incorporators choose, a specific purpose clause. Bylaws are the internal rules the board adopts for day-to-day governance: how meetings are called, how officers are elected, what committees exist.

These documents form a hierarchy. The MBCA lets a corporation adopt bylaws “not inconsistent with its articles of incorporation or with the laws of this state.”¹ If a bylaw conflicts with the articles, the articles control. If either conflicts with the state statute, the statute wins.

Express Powers

Express powers are the authorities a statute or the articles explicitly grant. Under MBCA § 3.02, every corporation “has the same powers as an individual to do all things necessary or convenient to carry out its business and affairs,” followed by a list that includes suing and being sued, owning and transferring property, making contracts, borrowing money, investing funds, and appointing officers and setting their compensation.¹ These attach automatically on incorporation. A corporation does not have to request them; the articles have to affirmatively restrict them for them to be lost.

A few of these deserve closer attention because they shape how corporations function.

Perpetual existence. Unless the articles say otherwise, a corporation has perpetual duration and succession in its own name. The entity survives the death or departure of any founder, shareholder, or director. That is why lenders extend credit against the corporation’s assets rather than against any individual.

Property and financial transactions. A corporation can purchase, hold, mortgage, and sell real and personal property. It can issue bonds, pledge assets as collateral, lend money, and invest surplus funds.

Compensation and benefits. The MBCA expressly authorizes pension plans, profit-sharing plans, and stock option plans for current or former directors, officers, employees, and agents.¹ This is statutory power, not merely something implied from the need to attract talent.

Participation in other entities. A corporation can serve as a partner, member, or manager of partnerships, joint ventures, trusts, or other business entities.

A Federal Limit on the Power to Lend

State law grants broad authority to lend, including to insiders, but federal securities law cuts back on that authority for public companies. Section 13(k) of the Securities Exchange Act, added by the Sarbanes-Oxley Act of 2002, makes it unlawful for any publicly traded company to extend or maintain a personal loan to any director or executive officer.² The prohibition covers direct loans, loans through subsidiaries, and material renewals of existing arrangements.

The restriction reaches only personal loans. A company can still issue a corporate credit card for business travel, advance relocation expenses subject to reimbursement, or extend ordinary consumer credit products on the same terms available to the general public. Loans outstanding on July 30, 2002, are grandfathered as long as their terms are not materially modified. Private companies are not subject to this prohibition, though their lending to insiders may still face state-law fiduciary scrutiny.

Implied Powers

Not every corporate action will appear in a statute or the articles. Implied powers fill the gap. They are the authorities a corporation reasonably needs to carry out its express purposes, and the MBCA’s language captures the breadth: “all things necessary or convenient” to carry out business affairs.¹ The “or convenient” is what gives corporations room to move without amending their governing documents whenever conditions change.

The analysis works from the express purpose outward. A company authorized to manufacture industrial equipment has the implied power to lease warehouse space, purchase liability insurance, hire safety consultants, and advertise its products. None of those need to be spelled out in the articles because none of them make sense without the manufacturing operation they support. A company with the express power to sell products internationally has the implied power to open foreign bank accounts and retain overseas counsel. Courts assess these claims by asking whether the action bears a reasonable relationship to the corporation’s stated business, not whether it was specifically contemplated when the articles were drafted.

The practical effect is that implied powers handle the vast majority of ordinary decisions. Hiring employees, entering office leases, purchasing software, retaining accountants: all flow from implied authority rather than express grants. A system that required a board resolution or charter amendment for every routine operational choice would stop commerce cold.

The Ultra Vires Doctrine and What It Once Did

Ultra vires is Latin for “beyond the powers.” It describes a corporate action that falls outside the scope of what the corporation is authorized to do. Historically, the doctrine had real teeth. If a corporation with a charter limited to textile manufacturing started lending money or buying unrelated real estate, an affected party could challenge the transaction. Courts could void contracts, award damages, and in extreme cases the state attorney general could bring an action to dissolve the corporation for exceeding its lawful purpose.

The traditional consequences created three enforcement paths. Shareholders could seek an injunction to block an unauthorized transaction before it closed. The corporation itself, acting through a receiver, trustee, or derivative action, could sue the directors or officers who authorized the act. And the state could bring proceedings against the corporation through its attorney general. Directors who knowingly approved ultra vires acts faced personal liability for any resulting losses, and D&O insurance policies typically excluded coverage for willful misconduct, so the exposure was uninsurable.

What Ultra Vires Means Today

The doctrine has been, in practice, almost abolished for most corporations. Two developments explain why.

First, general purpose clauses have become the norm. Under the MBCA and similar state statutes, a corporation that does not include a specific purpose in its articles is presumed to exist for the purpose of engaging in any lawful business. Most incorporators today either omit a purpose clause entirely or use broad “any lawful activity” language, so there is rarely a defined boundary for a corporate act to exceed. The doctrine still has practical significance when the articles contain a narrow purpose clause, but that pattern was common a century ago and is increasingly rare.

Second, MBCA § 3.04 directly limits when and how the doctrine can be raised. The statute provides that “the validity of corporate action may not be challenged on the ground that the corporation lacks or lacked power to act.”³ A third party who enters a contract with a corporation cannot later avoid the deal by claiming the corporation lacked authority to make it. The contract remains enforceable. This protects parties who relied on the corporation’s apparent authority and had no reason to scrutinize its charter.

The doctrine survives in only three narrow proceedings:

A shareholder can sue to stop an unauthorized act before it is completed. If the court finds the challenge equitable and all affected parties are before it, the court can enjoin or set aside the act and award damages for actual losses, but not for lost anticipated profits.³
The corporation, acting directly, derivatively, or through a receiver or trustee, can sue current or former directors, officers, employees, or agents who caused it to act beyond its powers.
The state attorney general can bring an action, including a dissolution proceeding under MBCA § 14.30, against a corporation that persistently exceeds its lawful authority.

The shift matters. Under the old framework, ultra vires could unwind completed transactions and leave both sides scrambling. Under modern law, the transaction stands and the remedy runs against the insiders who authorized it. The party who dealt with the corporation in good faith is protected.

Power Is Not the Same as Permission to Use It

Having a corporate power and exercising it wisely are different questions. Directors who wield corporate authority are bound by fiduciary duties that constrain how they act, even when they act within the corporation’s legal powers. The duty of care requires directors to inform themselves before deciding. The duty of loyalty prohibits self-dealing and undisclosed conflicts. The duty of obedience requires directors to keep corporate activities within the boundaries set by the charter, the bylaws, and the law.

When a director’s decision is challenged, the business judgment rule creates a strong presumption in favor of the board. A court will not second-guess a decision made in good faith, with the care a reasonably prudent person would use, and with a reasonable belief that it served the corporation’s best interests. The presumption disappears when the decision falls outside the corporation’s authority or serves the director’s own interests. That is where the express, implied, and ultra vires framework does its real work: it defines the outer boundary of what the corporation can do, and it defines where the protection of the business judgment rule stops.
