Law School Letters of Recommendation: Who to Ask, When, and How
Letters of recommendation are the most underrated component of the application. Three substantive letters add real signal; five mediocre ones subtract it. This guide covers how many to submit, who to ask in your specific situation, what makes a strong letter, and how to use the LSAC letter service.

How many letters do you need?
Most ABA-accredited law schools require 2 letters and accept up to 4. Three is the optimum for nearly all applicants. With 3 letters, you can demonstrate three distinct dimensions: academic depth, professional or extracurricular execution, and a third angle that fits your background.
Three substantive letters reliably outperform five thin letters at every tier. Admissions readers spend roughly 90 seconds per letter on average. A reader who skims four good letters in 6 minutes ends with a sharper picture of you than one who skims six average letters in 9 minutes.
Who to ask, by situation
Recent graduate (within 3 years of college)
Two professors plus one professional supervisor is the standard combination. Both professors should have taught you in upper-level seminars or supervised research where they observed your analytical work in depth. The professional supervisor adds dimension: a manager from a meaningful internship, research role, or post-graduation job who can speak to your work outside the classroom.
3 to 7 years post-graduation
One professor (if a strong relationship survives) plus two professional supervisors. After 3+ years, professional letters carry equal or greater weight. The professor letter should be from someone who genuinely remembers your work, not someone you took one class with five years ago. Better to drop the academic letter than submit a vague one.
Career changer (7+ years post-graduation)
Three professional supervisors is the right shape. Pick people who have managed you closely, ideally on substantive analytical or written work. Avoid extremely senior figures who barely know your day-to-day. Avoid clients or peers; admissions wants people who supervised your work, not collaborators.
Non-traditional applicant
Mix academic and professional based on the strongest relationships. Military service members can submit letters from commanding officers; academic researchers from PIs; volunteers from program directors. The principle: depth of relationship over title prestige. A detailed letter from an associate beats a vague letter from a CEO.
When to ask
Ask 6 to 8 weeks before your earliest application deadline. Senior faculty often write letters for many applicants in the same cycle; the writers furthest into the process produce the strongest letters. A request that arrives in early September for a November 15 deadline is comfortable; a request that arrives in late October is rushed.
Ask in person when possible. The conversation should be specific: confirm the writer can submit a strong letter (give them an out if they hesitate), name your earliest deadline, and offer to send your resume and personal statement draft. Follow up in writing within 24 hours with the materials and the LSAC submission link.
What makes a strong letter
Specifics over superlatives
A letter that says you were 'one of the strongest students of the past decade' is forgettable. A letter that names the specific paper you wrote, what you argued, how you revised it, and what the writer learned from your work is memorable.
Comparative judgment
Strong letters compare you to peers within a defined group. 'Among the top 5 percent of students I have taught in 20 years' carries weight because it places you. 'An exceptional student' does not.
Evidence of writing and analytical work
Law schools value writing. A letter that quotes a specific argument from your work or describes how you handled a hard analytical problem outperforms a letter that praises your work in general.
Length and depth
1.5 to 2 pages of substantive content. Letters under 1 page often signal a weak relationship; letters over 3 pages tend to dilute. Aim for the writer to have something specific to say in every paragraph.
The LSAC letter service
Letters submit through LSAC's Credential Assembly Service. The CAS letter service is included in your CAS subscription. Workflow:
- You add each recommender to your LSAC account, providing their email address.
- LSAC emails the recommender with a unique submission link.
- The recommender uploads the letter as a PDF.
- You assign each letter to specific schools as you submit applications.
- LSAC forwards letters automatically as part of your CAS report to each school.
Letters can be either targeted (the writer addresses a specific school by name; useful for schools where the writer has personal connections) or general (one letter for all schools). Most letters are general.
Confirm letters have arrived in LSAC before applications submit. CAS reports do not transmit until letters are received and applications are paid for. A delayed letter delays the entire application.
What to avoid
- 01Family members. Always inappropriate. Schools will discount the letter and read it as a signal you have no other options.
- 02Famous people who barely know you. A US Senator letter from someone who met you twice in 2022 hurts more than a thoughtful letter from a graduate teaching assistant.
- 03People you have not asked clearly and confirmed. Vague 'will you write me a letter?' produces vague letters. Ask in person, ask whether they can write a strong letter, give them an out.
- 04Last-minute requests. Request 6 to 8 weeks before your earliest deadline. Senior faculty with multiple commitments may need that lead time.
- 05Letters from people you graded over (in a TA or RA role). Even if the relationship is real, the dynamic can read poorly.
- 06Failing to waive your right to view. Most schools recommend waiving (FERPA waiver). Unwaived letters carry less credibility because the writer knows you will read it.
Frequently asked questions
How many letters of recommendation do most law schools require?
›
Most ABA schools require 2 letters and accept up to 4. The optimum number for most applicants is 3: enough to demonstrate breadth, not so many that the file feels padded. A few schools have specific configuration requirements (Yale and Stanford historically required 2 academic; check current policies). Submit additional letters only when each adds a distinct dimension the others do not cover.
Should I ask for academic or professional letters?
›
Recent graduates should weight academic. Within 3 years of college, schools expect at least one academic letter. Career changers (5+ years out) can submit fully professional letters. The principle: relationship depth over titular prestige. A detailed letter from a direct manager outweighs a vague letter from a senior executive who has only met you twice.
How far in advance should I ask for letters?
›
Ask 6 to 8 weeks before your earliest application deadline. Senior faculty often have multiple letter commitments concurrently; longer lead time produces a more considered letter. Ask in person when possible; follow up in writing within 24 hours of the conversation with the specifics they need: deadline, schools list, your resume, your draft personal statement, and the LSAC letter submission instructions.
What information should I give to my recommenders?
›
A short packet: your resume, a 1-page summary of why you are applying to law school (drawn from your personal statement), the list of schools and deadlines, and the LSAC submission instructions for the CAS letter service. Some applicants also include a list of specific projects or papers they did with the recommender. The goal is to make it as easy as possible for the writer to produce a specific, well-organized letter.
Should I waive my right to view the letter?
›
Yes, in nearly all cases. Waiving your FERPA right to view the letter signals to admissions that the letter is genuinely candid. Unwaived letters are common knowledge to be more guarded; admissions readers discount them accordingly. The only exception is if you have a specific reason to retain the right to read the letter; in that case, the cost of the unwaived signal generally outweighs the benefit.
Can I submit more than 3 letters?
›
Yes, but only if each additional letter adds a distinct dimension. A fourth letter that mostly duplicates the first three weakens the file. If you have 4 strong dimensions to demonstrate (academic depth, leadership, professional analytical work, public service, etc.), 4 letters can be the right call. Above 4 letters, almost no school benefits from the additional material.
How does the LSAC letter service work?
›
Letters submit to LSAC's Credential Assembly Service (CAS) once. From there, you assign letters to specific schools through your LSAC account. Letters can be 'targeted' to a single school (the writer mentions the school by name) or 'general' (the same letter goes to all schools you assign). Most letters are general. CAS forwards letters automatically as part of your school applications.
