Chambers vs Legal 500: how the two directories differ
Both directories rank law firms practice area by practice area using a written submission, a referee list and their own market research. The practical differences are in the detail. Chambers ranks in numbered bands and interviews a selection of referees. Legal 500 ranks in tiers, emails every referee submitted on time, and asks you to mark confidential text in bold red capitals.
The short answer
- Scale: Chambers uses numbered bands (it describes them as 1, highest, to 7, lowest). Legal 500 uses tiers, with firms listed alphabetically inside each tier.
- Matters: both accept up to 20 per practice area. Legal 500 wants at least one cleared for publication.
- Referees: Chambers caps the list at 20 or 30 depending on the guide and interviews a selection. Legal 500 treats 20 as a minimum guideline, sets no maximum and emails everyone submitted on time.
- Confidentiality: Chambers uses a separate Confidential section. Legal 500 wants CONFIDENTIAL in bold red capitals on the specific item.
- Timing: deadlines differ by guide and practice area at both. Check the deadline calendar.
Most firms that submit to one of these directories submit to both, often within weeks of each other. The work looks similar on the surface: a practice overview, lawyer nominations, a list of matters and a spreadsheet of referees (clients and others who can speak to your work). The rules underneath differ enough that a document written for one rarely suits the other without rework. This guide sets the official rules side by side.
Side-by-side comparison
| Topic | Chambers and Partners | Legal 500 |
|---|---|---|
| Ranking scale | Bands. "Law firms and individual lawyers are ranked in bands from 1 (highest) to 7 (lowest)." Some tables are unnumbered "Spotlight" tables, where all rankings are equal. | Tiers. "Firms are ranked alphabetically within tiers." |
| Individual categories | Bands plus Star, Senior Statesperson, Eminent Practitioner, Up-and-Coming and Associates to Watch. | US 2027 guidelines name four: Hall of Fame, Leading Partner (5+ years as partner), Next Generation Partner (up to 5 years) and Leading Associate. |
| How to submit | Word template plus Excel referee spreadsheet uploaded in MyAccount, or the Online Submissions portal. Chambers says the choice has no impact on ranking decisions. | Word template plus a separate Excel referee spreadsheet via the Legal 500 Submissions site. "Emailed documents will be deleted and will not be actioned." |
| Matter limit | Up to 20 work highlights per practice area, any mix of publishable and confidential. | Up to 20 transactions, cases or other work. At least one should be cleared for publication. |
| Review period | Work highlights "from the last 12 months". | Set per guide. US 2027: work between December 2025 and November 2026. |
| Referees | "Providing 20-30 referees … is essential." Cap is 30 in most guides, 20 in some sections, 5 per barrister in the UK Bar guide. Some sections take none. | "20 referees per practice area is a good minimum guideline." No maximum. All on-time referees are contacted by email. |
| How referees are approached | "We may interview some of your referees." Conversations are one-to-one and anonymised. | "All referees are emailed." Feedback is confidential and non-attributable. |
| Confidential material | Put it in the Confidential section. "Any information marked 'Confidential' will not be disclosed in any way." | Everything may be published unless marked "CONFIDENTIAL, in bold red and upper case". No blanket confidentiality statements at the front. |
| Feedback on last edition | The 2019 Chambers USA tips document points to sections C2 and C3 for feedback on coverage (dated guidance; check your current template). | A "Feedback on the [previous] edition" section invites a suggested ranking "based on evidence". |
| Interviews | "No, it's not essential." | "The absence of an interview does not negatively affect assessment." |
| Late material | Extensions are discussed with the section researcher. For UK, one or two days late needs no contact, but late referees may not be processed before research starts. | Late submissions "may not be given as full consideration". Late referees may be contacted much later or not at all. |
| Cost to submit | "Submitting to Chambers is free." | Editorial listing is "free of charge"; editorial and sales "operate independently". |

Bands vs tiers: what the numbers mean
A band is Chambers' ranking group within a practice-area table. Band 1 is the top group. A tier is the Legal 500 equivalent. Both directories rank firms and individual lawyers separately, so a lawyer can be ranked while the firm's team is not, and the reverse. Chambers states this directly in its methodology.
One practical point: Legal 500 says firms are listed alphabetically within a tier. Moving up or down the list inside a tier tells you nothing. Chambers does not publish a statement on ordering within a band, so avoid reading meaning into position there either.
Method: who decides and on what evidence
Chambers says it combines the submission with "reference feedback, client satisfaction indices, reputation in the market, peer knowledge and other discreet independent market sources", and that the research team, up to research directors, meets to set the final tables. Its published criteria include legal ability, client service, depth of bench, commercial awareness, diligence and cost-effectiveness.
Legal 500 describes its rankings as "comparative assessments" based on "the totality of evidence available", including submissions, track record, interviews, peer feedback and referee validation. Its criteria include complexity of work, depth of team, strength of client base and market reputation.
In both cases the submission is one input, not the decision. Chambers says plainly that "sending a submission does not guarantee a ranking".
Matters: same cap, different expectations
Both directories accept up to 20 matters per practice area. The difference is what each matter should contain. Legal 500 asks you to "identify the firm's role, indicate which partner(s) led the advice and mention start/end dates" and to identify the client. It also asks you to reflect "the breadth of the law firm's experience, not simply the biggest mandates". Chambers frames a work highlight around what happened and why it mattered. Our guide to writing Chambers work highlights covers this in detail.
If you submit to Legal 500 in a practice area for the first time, its guidelines suggest including "several examples from the previous two years, as well as at least 10 new examples of work".
Referees: capped list vs open list
This is where the two differ most. Chambers sets a ceiling per guide and section, usually 20 or 30, and interviews a selection. Legal 500 has no ceiling and emails everyone. A Chambers list should be your best-chosen contacts. A Legal 500 list can be longer, but every name will receive an email, so each person should expect it. See our Chambers referee spreadsheet guide for current caps by guide.
Confidential material: mark it the way each one asks
Chambers sorts matters into Publishable and Confidential sections. Legal 500 publishes anything not marked, and wants the specific confidential item marked, whether that is the client name, the value or the whole matter. A Chambers-style "everything below is confidential" heading does not meet Legal 500's rule against "global confidentiality restrictions at the front".
Timing
Neither directory has one deadline. Chambers sets deadlines per guide and practice area in its research schedule. For example, Chambers UK 2028 sections fall on 25 November 2026, 3 February 2027 and 31 March 2027. Legal 500 US 2027 editorial submissions and referees were due 13 November 2026. Dates move between cycles, so check the deadline calendar and each directory guide:
- Chambers UK and Legal 500 United Kingdom
- Chambers USA and Legal 500 US
- Chambers Europe and Legal 500 EMEA

Working across both
The efficient approach is one master record per matter, holding the facts both directories ask for: client, role, lead partners, dates, value where it can be shared, why it mattered and what is confidential. Each submission is then written from that record in the directory's own format. That is how we work. Talk to us if you want help preparing stronger, researcher-ready submissions for either directory.
Frequently asked questions
Can I reuse my Chambers submission for Legal 500?
The underlying matters can be reused, but the document cannot be sent as it is. Each directory has its own template, its own review period and its own way of marking confidential material. Legal 500 asks for the firm's role, the lead partners and start and end dates on each matter, and wants confidential text marked CONFIDENTIAL in bold red capitals. Rebuild the submission in each template from one master record of matters.
Is a Chambers Band 1 the same as a Legal 500 Tier 1?
Both are the top group in their table, but they are separate judgements made by separate research teams using their own evidence. Chambers says it ranks in bands from 1 (highest) to 7 (lowest). Legal 500 ranks firms in tiers and lists firms alphabetically within each tier. A firm can sit at different levels in the two directories.
Does either directory charge to submit?
No. Chambers states that submitting is free, and Legal 500 states that firms appear in its editorial sections free of charge. Both sell separate paid products such as profiles, and Legal 500 says its editorial and sales sides operate independently.
