An LLM (Master of Laws) is a one-year postgraduate law degree, typically pursued by people who already hold a first law degree, for the purpose of specializing in a particular area of law, qualifying to practice in a different country, or gaining an internationally recognized credential to complement a law degree earned elsewhere. It's one of the most common paths for internationally trained lawyers looking to work with, or in, common-law systems like the US or UK. This guide covers what the degree actually is at a basic level — if you've already decided you want an LLM and are choosing a program, or weighing it against a JD, the site has more detailed guides on those specific questions linked throughout.
What Is an LLM?
An LLM is a specialized postgraduate law degree, distinct from a first law degree (like a JD in the US, or an LLB in most common-law countries outside the US). It sits after a first legal qualification in the academic hierarchy — almost every LLM program requires an existing law degree or equivalent legal qualification for admission, which makes it fundamentally different from most other master's degrees that admit from any undergraduate background. An LLM is generally not a qualifying law degree on its own in the way a JD or LLB is — it's an add-on credential, most commonly pursued to specialize (in areas like tax law, intellectual property, international law, or corporate law) or to gain exposure to a different country's legal system.
For internationally trained lawyers specifically, an LLM from a US or UK law school is also a common route toward practicing in that country — though practicing generally requires clearing additional hurdles beyond the degree itself, most notably a bar exam, which isn't automatic just because you hold the LLM (more on this below).
Typical Structure and Duration
| Feature | Typical Range |
|---|---|
| Duration | 1 year full-time (the near-universal standard, unlike JD/LLB programs which run longer) |
| Format | Coursework-based; a thesis/dissertation option exists at some programs but isn't universal |
| Specialization tracks | Common — tax law, IP law, international law, corporate/commercial law, human rights law, and others, depending on the school |
| Typical entry requirement | An existing law degree (JD, LLB, or equivalent) from an accredited institution |
| Prior legal experience | Not always required, but many applicants have some practice experience before pursuing an LLM |
The one-year duration is fairly consistent globally and is one of the clearer structural facts about the degree — unlike, say, an MS, where duration varies a lot by country and program type.
Typical Cost
LLM programs vary in cost by country and institution, and — as with any graduate degree — the specific number depends heavily on the school and city rather than any single global figure. Programs at well-known US and UK law schools tend to sit at the higher end of postgraduate law degree costs globally; costs at other institutions and countries can be considerably lower. Because tuition changes year to year, check the specific program's current published cost rather than relying on a general estimate, and factor in the cost of living in what are often expensive cities (London, New York, etc.) where many LLM programs are based. Our LLM Application Guide and LLM in UK vs USA guides go into cost comparisons across specific countries and programs in more detail.
Career Outcomes
LLM outcomes depend heavily on what the degree was pursued for — specialization, jurisdiction-switching, or both:
- Specialization within existing practice — many LLM graduates return to practicing law in their home jurisdiction, now with a formal specialization (tax, IP, international arbitration, etc.) that strengthens their existing career
- Practicing in a new jurisdiction — for internationally trained lawyers, an LLM (often combined with passing a bar exam) can open the door to practicing in the US, UK, or another common-law jurisdiction — but this generally requires clearing that jurisdiction's separate bar admission requirements, which vary significantly by state/country and aren't guaranteed just by completing the LLM (see our US Bar Exam for International LLM Graduates guide for exactly which US states allow this route)
- In-house counsel and corporate roles — some LLM graduates move into in-house legal roles at multinational companies, where the international/specialized credential is often directly relevant
- Academic and policy roles — a smaller path, particularly for LLM graduates who go on to pursue further research (an SJD/PhD in law) or work in legal policy and international organizations
The degree's value is closely tied to having a clear reason for pursuing it — specialization, jurisdiction access, or both — rather than treating it as a generic credential boost on top of an existing law degree.
Who It's For (and Who It's Not For)
An LLM makes sense if you already hold a law degree and want to specialize in a particular area, want exposure to a different country's legal system, or are specifically working toward practicing in a jurisdiction like the US or UK as an internationally trained lawyer. It's a well-established, one-year route for all three of these goals, and it's the standard credential international lawyers use to build US/UK-facing careers.
An LLM is not the right starting point if you don't yet hold a first law degree — in that case, look at a JD (US) or LLB (most other common-law countries) instead, since the LLM assumes an existing legal qualification as a prerequisite. If you're trying to decide between starting with a JD versus going the LLM route as an international student, our JD vs LLM guide walks through that decision directly. And if you've already decided an LLM is right for you and are now choosing where to apply, our Top LLM Programs for International Students guide covers program selection in more depth than this explainer is meant to.
Because many LLM programs enroll a substantial international cohort, English proficiency scores (IELTS/TOEFL) are commonly required for admission — worth factoring into your application timeline alongside the LOR, personal statement, and transcript requirements most programs ask for.
