Law firms in Los Angeles: the largest firms, the market in numbers and how to choose one

This report is for anyone looking at Los Angeles law firms: a company or family choosing a lawyer, a law student or lateral comparing employers, an analyst sizing the market, or a business that sells to law firms. It gives the published headcount ranking, the Census Bureau's count of every law office in Los Angeles and Orange counties, the State Bar tools for checking a lawyer, and how to prospect firms of each size.

The largest law firms in Los Angeles

The Los Angeles Business Journal ranks law firms each year by the number of attorneys in Los Angeles County. Its list of 19 May 2025 put these ten on top:

The firms supplied the figures, and the Journal marks its own estimates. The count covers Los Angeles County only, so a firm's Orange County lawyers aren't in it, and it ranks size, not quality. All ten have offices outside Los Angeles: by the Journal's office counts, Munger, Tolles & Olson has the fewest (three), and Lewis Brisbois the most (55). The Journal publishes a new edition each spring, so check the date before you quote a number.

Los Angeles law offices in Census data

County Business Patterns (CBP) 2023 counts offices of lawyers (NAICS 541110) in the Los Angeles-Long Beach-Anaheim, CA Metro Area (CBSA 31080), which is Los Angeles County plus Orange County.

Grouped, 10,584 offices have 1 to 19 employees, 659 have 20 to 99 and 87 have 100 or more. New York's five boroughs have nine law offices with 1,000 or more employees; Los Angeles has none, and its four largest sit in the 500 to 999 class. That fits the ranking: LA's biggest firms run large offices, but their lawyers are spread across Downtown, Century City and other sites. Los Angeles County holds 75% of the metro area's offices and 77% of its law-office jobs.

What the Census count leaves out: it counts establishments with paid employees, not firms, so a firm with Downtown and Century City offices counts twice. Solo lawyers without staff aren't included, because the self-employed are out of scope; the Census Bureau's Nonemployer Statistics count 16,909 legal services businesses with no paid employees in the metro area in 2024, a broader category that includes them. "Employees" covers everyone on the payroll, from paralegals to associates, and partners who own the firm aren't employees. In-house legal departments and government lawyers are counted in their employers' industries, not here.

How many lawyers practice in California

The State Bar of California's demographics page counted 201,374 active licensees on 29 October 2026, plus 75,431 inactive licensees, 2,318 judges and 22,599 not eligible to practice: 301,722 in all. The American Bar Association's 2025 profile, reported by the ABA Journal, put California's active lawyers at 181,048, second to New York. The two counts use different definitions and dates. The State Bar doesn't publish county totals on that page; it points requests for county data to its public records portal.

How California firms are organized matters when you vet one. The State Bar says professional corporations practicing law must be registered with it, and that it "does not certify an LLC within California for the purposes of practicing law." Most firms are therefore sole practices, partnerships (often LLPs) or registered law corporations.

How to choose a Los Angeles law firm

1. Name the matter and the court. An unlawful detainer in Van Nuys, a trademark filing and a Delaware merger need different firms; filter by practice area before size.
2. Use a certified referral service if you don't have a name. The State Bar's Los Angeles list includes the Los Angeles County Bar Association's SmartLaw service, bar-run services for the San Fernando Valley and the South Bay, and specialist services such as California Lawyers for the Arts. The State Bar certifies these services, and you can complain to it about one.
3. Check the attorney profile. The State Bar's search shows each lawyer's license status, discipline and administrative history. Check every lawyer named in the engagement letter.
4. Look for a certified specialist if your matter falls in one of the areas the State Bar certifies; its specialist search lists them.
5. Agree the fee in writing, and know that LACBA runs fee dispute arbitration and mediation if a bill is contested later.

Prospecting Los Angeles law firms

Check the bar's vendor landscape before you pitch. LACBA's home page features member-benefit providers such as MyCase, LawPay, First Legal, Rev and TimeSolv, so its members have already heard those offers. For roles and buying committees by firm size, see selling to law firms.

Illustrative example. The company, rates and results are invented.

Harborline Legal Staffing (harborline.example) places contract paralegals and wants offices of 20 to 249 employees: 503 + 156 + 68 = 727 in the metro. It drops branches of national firms that hire through a central HR team, about 35% on its own review, leaving roughly 473 accounts. With two contacts each (the firm administrator and a litigation partner), that's 946 people. A 3% reply rate gives about 28 conversations, and if one in five sends a job order, about six orders. Every point of reply rate is worth two more orders, which is why the research behind each first line matters. Bebop finds firms that match a description like this and writes an account playbook for each one.

Hi [first name], it's [your name] from [company]. I'll be quick: I saw [firm] is hiring a litigation paralegal in [office], and it's been open about [weeks]. We keep a bench of paralegals who already know LA Superior Court e-filing, and we can usually have two résumés to you in 48 hours. Is the role still open, and who's running the search?
