There are over 33 million small businesses in the United States, according to the U.S. Small Business Administration. Many of them rely on both corporate and commercial legal frameworks.
Corporate law and commercial law are closely related areas of business law in the US, but they serve different purposes. And understanding these distinctions is necessary to handle the legalities of a business.
Let’s understand these differences to ensure compliance, manage risk, and operate effectively. We’ll also tackle the important role of corporate and commercial solicitors in this area of the law.
What Corporate Law Covers
State law serves as the primary legal framework for corporate law, establishing rules for business entities, including their formation, internal governance, corporate dissolution, and operational functions, which extend to limited liability companies and limited partnerships.
The American Bar Association states that Delaware's General Corporation Law (DGCL) serves as the primary legal framework that regulates both publicly traded companies and most private businesses throughout the United States. 36 US jurisdictions have adopted either complete or partial sections of the Model Business Corporation Act (MBCA).
Corporate law involves understanding entity formation, required filings, shareholder rights, and the duties of directors and officers. It also involves rules on governance, voting, dividends, mergers, and fiduciary responsibilities.
Companies use equity or debt securities to collect funds from investors, which creates an intersection between corporate law and federal securities regulations because the Securities Act of 1933 and the Securities Exchange Act of 1934, together with state corporate laws, all apply to this process.
Corporate law matters arise from three types of issues, which include fiduciary duty violations and flawed mergers and shareholder conflicts.
What Commercial Law Covers
Commercial law establishes rules for business operations that commence once a business starts functioning. The Uniform Commercial Code (UCC) serves as the primary commercial law authority in the United States because it functions as a model statute that all 50 states and the District of Columbia and most U.S. territories have enacted with different state-specific adaptations.
Article 2 controls all transactions that involve goods, while its rules establish special provisions for merchants who need to create contracts that define delivery and acceptance and breach and remedies. Article 3 describes negotiable instruments, including checks and promissory notes. Article 4 regulates both bank deposits and bank collection activities.
Article 9 serves as a crucial article for commercial applications because it controls secured transactions, which involve using personal assets as loan security. The 2022 amendments to the UCC added Article 12, which covers controllable electronic records and digital assets, to reflect the transformation of commercial activities into digital marketplaces.
Commercial law exists outside the UCC. It includes common law contract principles that govern service agreements, agency law, and trade practices regulation, as well as all other transactions not covered by the UCC. Consumer protection law exists in some situations that overlap with commercial law and common law contract principles.
A contract dispute over a shipment of goods, a lender's security interest in business inventory, or a dishonored check is a commercial law matter. Commercial disputes against companies can get very complicated. That’s why it’s important to hire an experienced attorney that is more than capable of taking on the challenge, says Jefferson Parish commercial litigation lawyer Scott Huete.
Where the Two Bodies of Law Diverge
The primary difference between corporate law and commercial law arises from their divergent areas of application and their distinct legal matters.
Corporate law governs the lifecycle of a company, which includes its creation and its internal governance and all relationships between company owners and management. Commercial law governs all transactions of an entity, which include its purchasing and selling activities and its borrowing and lending practices and its methods of enforcing or defending its agreements.
Corporate law applies to the particular organizational form in question and may differ between a corporation and an LLC even in the same state. The UCC commercial law system applies to business transactions that involve any type of entity, from sole proprietors to publicly traded corporations, when they make contracts that include goods sales under Article 2.
Corporate law establishes future business operations through governance rules, which determine how companies will function throughout their existence. The rules of commercial law establish the framework that governs all business transactions.
Where the Two Bodies of Law Intersect
Companies and commercial law sectors function together because they need to operate simultaneously without separation. The UCC Article 2 regulations control the sales terms of a supply contract that a corporation negotiates, while the state's corporate law governs the internal authorization process that an officer must follow to bind the company.
The business uses its accounts receivable as collateral for a line of credit, which results in the application of Article 9 of the UCC together with the organizational documents and governance requirements that permit the transaction.
The most visible example of this pattern exists through mergers and acquisitions. Corporate law establishes the rules that control board and shareholder approval along with fiduciary duties and entity-level mechanics to oversee a corporate acquisition.
The purchase agreement functions as a commercial contract, which general contract principles govern, while goods involved in the transaction may also fall under the UCC's jurisdiction.
Practical Implications for Businesses
The selection of applicable legal frameworks determines which inquiries a business needs to pursue and which experts it should hire. Business organization attorneys handle corporate law matters, including entity structure, equity issuances, governance disputes, officer authority, and fiduciary obligations.
The practice of transactional law handles all commercial law matters, which include contract terms and secured lending and negotiable instruments and trade practices through attorneys who focus on agreements and financing matters.
The execution of complex transactions needs both perspectives because their absence creates actual legal risks.
Key Takeaways
Corporate law and commercial law handle distinct aspects of business operations. Corporate law establishes the rules that determine how business entities should operate their internal functions and their organizational structure and leadership systems based on state laws such as the DGCL and MBCA.
Commercial law defines the legal framework that governs business transactions through the UCC and common law contract principles. The two bodies of law operate in parallel and overlap regularly in complex transactions.
Businesses that understand which framework governs a given situation are better positioned to structure agreements, allocate risk, and identify when specialized legal counsel is needed.
