This is not a comprehensive list, but some of the most popular law school specializations that exist today:
Business Law
Business law deals with aspects of the law having to do with industry and commerce — from taxes and liability to licensing and trademarking. This extremely wide section of the law branches out into numerous areas of expertise.
Small-business law
Often focuses on the kind of legal counsel needed during the early years of a business, such as tax classifications, hiring employees, and the proper zoning and licensing needed to start a business.
Corporate law
More likely to deal with the financial and structural status of an established company, as well as the provision of legal advice on day-to-day dealings.
Criminal Law
Criminal law revolves around governmental prosecution of anyone who is purported to have committed a criminal act, as defined by either local, state, or federal penal codes.
Environmental Law
Environmental law involves the interpretation and enforcement of laws and standards that would protect the environment from public and private actions.
Intellectual Property Law
Intellectual property (IP) law has seen tremendous growth in the past decade. It is a general category of law that deals with the acquisition and enforcement of patents, trademarks, and copyrights. IP law can traditionally be broken down into three subdivisions:
Patent law
Focuses on inventions and technology.
Public Interest Law
Focuses on the well-being, the rights, health, or finances of the public at large, most commonly advocating for those living in poverty or marginalized populations.
Trademark law
Designed to defend an individual's or a company's investment in any distinguishing name, symbol, or device.
Copyright law
Deals with the protection of literary, artistic, and musical works.
Joint Degree Programs*
In addition to offering specialized areas of study, many law schools have instituted formal dual-degree programs that offer students the opportunity to pursue a Juris Doctorate (JD) degree while also working toward a Master's degree. Although the JD/MBA combination is the most popular joint-degree sought, many universities offer a JD program combined with Masters' degrees in areas like public policy, public administration, and social work. Although they take more work, dual degrees may make some students more marketable for certain positions. (*Depends on the school, joint degrees can vary)
