Top 10 Biggest Law Fields by Revenue
The United States legal industry consists of legal fields that generate billions of dollars annually, shaping the country's economy and business landscape. Below is a detailed analysis of the current top areas of law based on their revenue for 2024 and 2025.
Recent data from authoritative sources shows that business law is the top field in the United States, generating $191.8 billion in revenue in 2025.
1. Business Law
Industry Revenue: $191.8 Billion
Business law ranks as the top contributor to the nation’s legal economy, generating a massive $191.8 billion in revenue. This field has been growing steadily as companies expand and require more legal support, showing a direct proportional relationship between economic growth and the demand for business legal services.
In 2024, an estimated 33.2 million businesses operated across the United States, ranging from startups to large corporations. With such a high volume of active businesses and increasingly complex regulations, companies rely on legal professionals to manage everything from daily operations to major expansions. Large law firms particularly excel in this field due to their greater resources and ability to serve clients across multiple states and countries.
2. Corporate Law
Industry Revenue: $165.2 Billion
Corporate law follows closely behind at $165.2 billion in revenue. The field experienced a major spike in 2021 when IPOs and corporate acquisitions hit record highs, driving surging demand for corporate legal services. Corporate lawyers assist with mergers, incorporations, acquisitions, and ensuring compliance with regulations.
Although the pandemic briefly slowed the industry, corporate law has proven resilient. Firms based in major cities like New York and Chicago remain top earners, especially those serving international clients with cross-border legal needs.
3. Intellectual Property Law
Industry Revenue: $65.5 Billion
As innovation drives the modern economy, intellectual property (IP) law has become increasingly valuable, generating $65.5 billion annually. These lawyers protect the creative and technical assets that make businesses unique – patents, trademarks, copyrights, and trade secrets.
The surge in technology, the rise of digital creative assets, and the increased ability to share information have fueled demand for IP legal services. As tech companies continue to develop new products and services, the need for IP protection grows, making this a secure and thriving legal field for years to come.
4. Personal Injury Law
Industry Revenue: $57.3 Billion
Nearly 400,000 personal injury claims are filed each year across the United States, most of them in state courts. Despite advances in safety measures, the demand for legal services in this area continues to grow. With a large client base and consistent case volume, the personal injury field is projected to generate $57.3 billion in 2025. Automobile accidents continue to account for more than half of this revenue, even with ongoing improvements in vehicle safety.
The Southeast region, which has the highest share of the U.S. population, represents the largest client base for this field. However, the competition among firms is intense, a benefit for clients, as firms work hard to build strong reputations and deliver consistent results.
5. Employment Law
Industry Revenue: $25.5 Billion
Employment law revenue reached $25.5 billion in 2024, driven by evolving workplace rules and increased employee awareness. The rise of remote work, the growth of the gig economy, and an increase in wrongful termination claims have created new legal opportunities. Boutique firms specializing in specific areas of employment law are gaining market share and competing effectively with larger practices due to their focused expertise.
6. Estate Law
Industry Revenue: $18 Billion
The growing population of Americans reaching retirement age is fueling demand for estate planning services. According to data from the Urban Institute, the number of Americans aged 65 and older is projected to more than double over the next 40 years, reaching 80 million by 2040.
Wealth transfer is booming as baby boomers begin passing down assets to younger generations, creating the largest inheritance wave in U.S. history. The COVID-19 pandemic further raised awareness around the importance of estate planning. As a result, revenue in this industry has steadily climbed to $18 billion and is expected to continue rising.
7. Family Law
Industry Revenue: $13.2 Billion
While divorce rates have declined, divorce-related matters remain the primary source of income for family law firms, which generate over $13 billion annually. Rising disposable income has made legal services more accessible, even as many individuals turn to online platforms and nonprofit alternatives.
Family law firms face growing competition from online services, but complex cases still require the expertise that only experienced attorneys can provide, especially in high-population states like Florida and Georgia.
8. Immigration Law
Industry Revenue: $9.9 Billion
Immigration law remains a vital, high-revenue field, generating $9.9 billion annually. The COVID-19 pandemic temporarily boosted demand as migrants faced new travel restrictions and needed legal guidance to navigate shifting immigration policies.
Today's immigration attorneys often need to speak multiple languages to serve diverse client populations. This field sees particularly high demand in tech-heavy regions like the West Coast, where companies frequently recruit international talent.
9. Healthcare Law
Industry Revenue: $6.9 Billion
Healthcare law faced significant challenges during the pandemic, with many legal matters paused as the industry focused on crisis response. As a result, the sector experienced a revenue decline at a compound annual rate of 1.4% through 2024. Still, it remains a $6.9 billion industry with long-term growth potential.
Healthcare lawyers help medical organizations with regulatory compliance, fraud prevention, and antitrust matters. As healthcare systems stabilize and reforms continue, this legal field is expected to regain momentum and deliver sustained demand.
10. Bankruptcy Law
Industry Revenue:$6.1 Billion
Bankruptcy law works differently from most legal fields, it actually does better when the economy struggles. Its revenue is inversely tied to the overall health of the economy. Currently, the field generates $6.1 billion annually, though that number is expected to decline as the economy recovers.
However, as economic growth slows, bankruptcy lawyers may see increased demand. This counter-cyclical nature makes bankruptcy law an interesting specialty. It thrives during downturns, offering recession-resistant career opportunities when other practice areas may see a decline.

The highest-earning legal fields are closely tied to business activities. The top three money-making areas are Business Law ($191.8 billion), Corporate Law ($165.2 billion), and Intellectual Property Law ($65.5 billion).
