What this study says.
The wealthiest families in America have stopped asking Google who their next trusts and estates attorney should be. They are asking ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. And the firms that built their reputations on quiet partner-driven referrals are losing the new referral channel before they know it exists.
This is the first study to rank the leading private client law firms in both New York and Los Angeles by modeled AI Citation Share across the five engines now dominating UHNW research. Fifty firms — twenty-five per city — across seventy-two high-intent prompts and five Citation Share dimensions.
Four findings drive the report. One: bicoastal beats monoastal. McDermott Will & Emery, Loeb & Loeb, Withers Bergman, and Holland & Knight rank in both city top-tens. The firms with serious offices in both cities win the cross-city retrieval question by default. Two: Hollywood pulls LA into its own gravity. Loeb & Loeb's LA office is the highest-cited single-city office in the index — driven by entertainment-industry estate work that AI engines retrieve with extreme specificity. Three: Withers is structurally winning the cross-border category in both cities. An estimated 22% of all Sub-Category 3 (cross-border) citations across both cities concentrate on one firm. Four: the regional boutiques are invisible. Several Chambers Band 1-ranked NYC and LA boutiques have effectively zero AI surface area. The credentials exist. The retrieval does not.
How the index is built.
The EPR Legal AI Visibility Index models how often, how favorably, and with what specificity each firm is named in response to a fixed set of high-intent prompts across five AI engines. It does not log live query runs. Estimates are directional, derived from systematic analysis of each firm's public content surface area, partner-level digital footprint, third-party recognition (Chambers High Net Worth, Best Lawyers, Legal 500 Private Client), and known training data exposure.
The five AI engines tested
Universe
Fifty law firms — 25 NYC, 25 LA — with named trusts & estates, private client, or wealth planning practices serving high- and ultra-high-net-worth families. Selection criteria: minimum five named T&E partners with public profiles; recognition in Chambers High Net Worth, Best Lawyers, or Legal 500 Private Client; discoverable practice-area page; active matters in the relevant Surrogate's / Probate Court.
The five Citation Share dimensions
Composite score
Each dimension is normalized 0–100 and weighted equally. The composite is reported on a 0–100 scale. Differences inside ±3 points should be treated as noise; differences above 7 are meaningful.
Disclosure
EPR Legal is editorial and independent. This study was not commissioned or paid for by any firm in the universe. No firm received pre-publication access to its score.
Seventy-two prompts. Six sub-categories.
The prompt set mirrors the high-intent research a UHNW principal or family-office gatekeeper actually runs in each city. The same six sub-categories are tested in NYC and LA versions of each prompt — total 36 NYC prompts, 36 LA prompts.
1 · Estate Planning & Dynasty Trust Structuring
The volume category. Foundational generational wealth planning.
2 · Premium Finance & Life Insurance Trust Structures
The Haute Wealth adjacency. Where the wealth bar meets the premium financing world.
3 · Cross-Border & International Private Client
Where the international firms historically dominate — and the gap is widest.
4 · Tax Controversy & Audit Defense
The audit-defense bench. Highest fee density per matter.
5 · Trust Administration, Fiduciary & Family Office Counsel
The ongoing-relationship side of the practice. Where retention compounds.
6 · Entertainment & Talent Estate Planning (LA-weighted)
The category where LA pulls away. Performer, athlete, and entertainment-executive estates.
New York City — twenty-five firms.
Composite scores across 36 NYC-specific prompts, all five engines, all five dimensions. Directional.

The firms AI names first.
The most-cited T&E group in the index, in both cities. The driver is volume — McDermott publishes more substantive private-wealth content than any peer, and its partners (notably in the Chicago–New York–LA axis) appear by name across multiple engines. Where competitors run quiet, McDermott runs loud. Chambers ranks McDermott's private wealth practice as a leader in California; the firm has been recognized for cross-border ultra-wealthy work on a US-Nationwide basis.
Strongest engines: ChatGPT and Claude. Slightly weaker on Perplexity, which under-cites the firm relative to the field.
Highest specificity score in the index. When AI engines answer T&E questions, they name Loeb partners directly — David C. Nelson is cited frequently as co-chair of the Trust & Estate Litigation Practice. The driver is the firm's entertainment-industry estate work — high-profile clients generate high-profile coverage, and AI engines are trained on that coverage. Loeb is the only firm in the index where the LA office ranks higher than the NYC office.
Per Chambers: Loeb is "especially strong in California" with a noteworthy practice in DC. The bicoastal positioning is reflected in citation diversity.
The international play. Withers built its content infrastructure for global retrieval before American competitors knew the channel existed. The firm dominates Sub-Category 3 (cross-border) prompts in both cities — Elizabeth A. Bawden in the LA private client and tax team is cited consistently. Chambers describes Withers as "a major player in private wealth with a strong international practice"; the LA and San Diego offices add litigation depth.
Partner-level specificity is the highest in the index. A model the American T&E bar should be studying.
The highest-cited single-city LA firm in the index. Greenberg Glusker specializes in estate planning for high net worth individuals and families with significant cross-border mandates, including high net worth immigration and relocation. The firm's Hollywood and entertainment-family-office practice is cited consistently across engines. Trust & estate litigation practice adds depth on Sub-Category 5 prompts.
Rachel J. Harris is cited as a leading practitioner for domestic and international estate planning, pre-immigration planning, and operations of tax-exempt organizations. The international counsel pull on inbound Asian and European family money is a structural advantage.
The pure-play winner. Day Pitney's individual clients team has, per Chambers, "a huge amount of experience advising private clients on their wealth planning" and is "particularly well known for its expertise in advising on cross-border matters." The firm's private client group is the largest dedicated T&E practice in the NYC index by partner count, and the firm's content posture is unusually generous — frequent publishing, named-partner articles, regulatory commentary. It pays. Day Pitney is the most-cited firm in the index on Sub-Category 2 (premium finance / ILIT) prompts.

What AI is missing.
Across the 72-prompt set across both cities, the engines surfaced an estimated 37 firms with material T&E reputations that are entirely absent from the citation distribution. The pattern is consistent: deep partner expertise, thin content surface area.
| Firms named by Chambers HNW Band 1, invisible to AI | Multiple Band 1-ranked NYC and LA boutiques have effectively zero AI presence on any of the 72 prompts. The credentials exist. The retrieval surface does not. |
| Prestige firms cited by name, never by partner | Sullivan & Cromwell, Davis Polk, Gibson Dunn, Munger Tolles — AI engines recognize the firm but rarely name the T&E partners running the practice. The brand is cited. The bench is invisible. |
| Cross-border is one firm | Withers Bergman's dominance is so large that AI engines treat the category as a one-firm answer. Every American firm with a strong cross-border practice is competing for the remainder. |
| LA pulls 5W's media gravity | Entertainment-industry citations compound twice in LA — once for the firm, once for the named celebrity. The firms with active Hollywood matters benefit from cross-citation echo. The firms doing pure family-office work in non-entertainment industries are structurally underweighted in LA-specific prompts. |
Three key findings.
1 · Publishers are winning. The discreet are losing.
The top five firms publish T&E content at a rate roughly 4–6× the bottom quartile. Discretion is a virtue for client work. It is a liability for retrieval. The historical assumption that the wealth bar wins through quiet excellence is being inverted by AI.
2 · Partner specificity is the new differentiator.
Firms cited by name only lose the warm-introduction advantage to firms where AI engines surface a specific lawyer. UHNW prospects asking AI for an advisor want a name, not a firm. Loeb (David Nelson), Withers (Elizabeth Bawden, Rachel Harris), Holland & Knight (Cindy Brittain) are converting this signal directly.
3 · Bicoastal is the new monopoly.
Four firms appear in both cities' top tens: McDermott, Loeb, Withers, and Holland & Knight. Bicoastal positioning compounds retrieval — cross-city prompts default to firms with offices in both. Pure single-city firms compete only within their city for citations they could share across both.
What this study is and isn't.
Directional, not exact. Citation Share is modeled from systematic analysis of public content surface area, published thought leadership, partner-level digital profiles, Chambers HNW, Best Lawyers, and Legal 500 Private Client rankings, and known AI engine training data exposure. Not from logged live query runs. Differences inside ±3 points should be treated as noise. Differences above 7 are meaningful.
What it captures. The likelihood that a UHNW researcher running the 72-prompt set encounters each firm across the five engines. Citation Share is an estimate of mention-weight, not legal quality.
What it does not capture. Internal firm quality, partner-level technical expertise, fee competitiveness, or client outcomes. A low Citation Share indicates a weak retrieval surface — not a weak T&E practice.
