What is the cover letter actually doing in the file?
For most screening readers, your cover letter is doing two jobs. First, it is a short writing sample produced without a supervisor's edits. A letter with a comma splice, a passive-voice pileup, or last firm's name still in paragraph two tells a hiring partner more than your legal writing grade does. Second, it answers the only question the resume cannot: why this employer, this practice, this city, right now.
Understand the read. At a large firm, a recruiting professional or junior associate spends well under a minute per application. The letter is mostly a screen-out device at that stage. At a small firm, a government office, a public interest organization, or chambers, the letter is a genuine screen-in device, because those employers get fewer applications and care intensely about whether you actually want to be there rather than defaulting to them after striking out elsewhere.
That asymmetry should drive your effort allocation. A mass-mail letter to 60 firms should be clean, correct, and customized in one paragraph. A letter to a five-lawyer plaintiff-side employment firm you genuinely want should be researched and rewritten from scratch.
What goes in each paragraph?
Use three or four paragraphs and 250 to 350 words. Anything longer signals you cannot self-edit. The structure below works for nearly every legal employer.
Write the middle paragraph in evidence, not adjectives. "I am detail-oriented and hardworking" is invisible. "As a research assistant to Professor Kim, I cite-checked and Bluebooked a 120-footnote article on ERISA preemption and drafted two summaries of circuit splits that appear in the published version" is not. If you have a published note, refer to it in proper form on the resume and by short description in the letter: Author, Note, [Title], [vol.] [Journal] [page] ([year]).
- Paragraph 1 (2-3 sentences): who you are (year, school), exactly what you are applying for (2L summer associate, summer intern, 2027 term clerkship), and the referral or source. Lead with the referral if you have one: "Sarah Nguyen, an associate in your Chicago litigation group, suggested I write to you."
- Paragraph 2: why you can do the work. Pick two or three concrete items — clinic matters, prior-career expertise, journal work, a language, a technical background, a prior legal internship — and show what you produced and for whom.
- Paragraph 3: why this employer. One specific, verifiable reason plus a real geographic or subject-matter tie. This is the paragraph that must change for every application.
- Closing (2 sentences): note the enclosures (resume, transcript, writing sample, references), state availability, and thank them. No demands for a meeting; "I would welcome the chance to interview" is enough.
How do you write the 'why this employer' paragraph without flattery?
Ban the phrases "prestigious," "world-class," "collegial culture," and "commitment to excellence." They are true of every employer and therefore say nothing. Instead, find a fact and connect it to something you have already done.
Sources that produce facts: the firm's practice-group pages and representative-matter lists; the NALP Directory of Legal Employers for practice mix, class size, and pro bono policies; recent filings or opinions in the office's matters (Westlaw, Lexis, PACER, Law360, Bloomberg Law); alumni in your school's database whom you actually emailed; a specific attorney's article or CLE panel. Then say why it matters to you: "Your health care regulatory group's work on 340B disputes is close to what I did for three years as a hospital compliance analyst, and it is the reason I came to law school."
Geographic ties matter more than students expect, especially in secondary markets and for judges. If you have one — family, undergraduate school, prior job, spouse's residency, bar exam already scheduled in that state — state it plainly in one sentence. If you do not have one, do not fake it; give the substantive reason instead.
How does the letter change by employer type?
Large firms: shortest letters, most customization pressure on one paragraph. If you are applying to a specific practice group, say so; if you want to stay generalist, say that instead of pretending to a passion for tax. Address it to the hiring partner or recruiting manager named on the firm's website or in the NALP directory.
Judicial clerkships: the letter is short and formal. Address the envelope and inside address to "The Honorable Jane R. Doe, United States District Court for the District of Massachusetts" and open with "Dear Judge Doe:". Federal applications generally run through OSCAR, which caps document length and formats; state courts vary wildly, and some judges post their own instructions. Say what term you are applying for, list your recommenders by name, note any tie to the district, and stop. Do not tell an Article III judge that you admire her jurisprudence unless you can name the opinion and say something non-obvious about it.
Government: many federal postings run through USAJOBS or an honors-program portal with rigid requirements, and some do not accept a cover letter at all — follow the posting exactly, because non-compliant applications are discarded before a human reads them. If a letter is allowed, name the specific office or division, mention citizenship and clearance eligibility if requested, and note your expected bar admission date and jurisdiction.
Public interest and small firms: the longest and most personal letters, and the ones where commitment evidence carries the most weight. Show a track record — volunteer work, prior organizing, a clinic case, a summer at a similar office — and demonstrate you understand the client population and the funding reality. For plaintiff-side and small firms, signal that you can carry files early and that you are not waiting for a big-firm offer.
What are the formatting and submission mechanics?
Use single-spaced block format: your address block, date, recipient's full name, title, firm, and address, then a colon salutation. No indents, one blank line between paragraphs. Times New Roman, Garamond, or Century Schoolbook at 11 or 12 point, one-inch margins, one page with white space left over. Close with "Sincerely," four blank lines, and your typed name; a scanned or drawn signature is optional and never required.
Send a PDF unless the application system demands .docx. Name the file so it survives a shared drive: Doe_Jane_Cover_Letter.pdf. Combine resume, transcript, and writing sample into one PDF only when the instructions ask for it.
Salutations: use a real name whenever you can find one. "Dear Hiring Committee:" is acceptable when you cannot. Never "Dear Sir or Madam," "To Whom It May Concern," or "Hi." Do not put "Esq." after a recipient's name in the inside address if you are also using "Ms." or "Mr." — pick one. If you email the letter, put the same text in the body and attach the PDF; do not write "please see attached" and nothing else.
What gets you cut?
The failures are boringly consistent, which means they are avoidable. Read your letter aloud before sending, and run a find-and-replace check on every proper noun.
Also avoid: exclamation points, "I believe I would be a great fit," "I am extremely passionate about the law," a full paragraph narrating why you went to law school, apologizing for grades, and quoting the firm's own website back to it.
- Wrong employer name, wrong city, or wrong judge's title left over from the last version.
- A letter that is a prose resume — same facts, more words, no new information.
- Typos and Bluebook errors in a document you are submitting as proof you can write.
- Explaining what a 1L summer internship would do for your development; employers hire for their needs, not your growth.
- Overclaiming a connection: naming an alum you never spoke to, or a practice area you cannot discuss for two minutes in an interview.
What varies by school and what should you check first?
This varies by school, and the variation is real. Many career offices require you to submit a draft for review before you can apply through Symplicity, 12Twenty, or the school's own bidding system; some maintain a mandatory template or letterhead; some prohibit outbound applications during OCI blackout periods. Check your career services handbook before you draft, not after.
Whether a cover letter is required at all also varies. Many on-campus interview bids accept only a resume, transcript, and grade sheet, while write-in and direct applications almost always require a letter. Some judges expressly say they will not read one. Follow the posted instruction over any general rule in this guide.
Timing for 1Ls varies too. Most law schools, following longstanding NALP guidance, bar employers from contacting or interviewing 1Ls before December 1, and public-sector and honors programs often have fixed fall or early-spring deadlines that are far earlier than firm hiring. Ask your career office for the specific dates your school enforces, and calendar the deadlines for DOJ and other federal honors programs separately, because they do not move for you.
