Why Is ChatGPT Recommending a Former Partner's New Firm After a Partner Departure?

Why does the reputation move with the partner?

AI assistants recommend professional firms mainly through third-party signals: directory rankings, awards, articles, reviews and news coverage. In many practices, those signals are attached to individuals:

The lateral move announcement is often the single most influential document. It usually summarises the partner's expertise, rankings and notable work, and names the new firm, in one clear, recent page. For a question like "best employment lawyer in Denver", that page is exactly what a search-based answer can draw on.

Why does your firm lose visibility at the same time?

• The bio disappears. The old firm's page that connected the partner's reputation to the firm is deleted, often leaving a broken link.
• Practice pages were built around one person. If the practice area page said "led by Jane Smith, ranked in...", it now has little evidence left.
• The team may have moved too. When associates or a whole group follow, the firm has less expertise in that area in practice, not just on paper.
• Directories lag. Rankings may not reflect the remaining team until the next research cycle.

How do you check what assistants are saying?

Run these questions in ChatGPT, Google's AI Overviews and AI Mode, Gemini, Perplexity and Copilot, two or three times each:

• "Best [practice area] lawyer (or accountant, consultant) in [city]"
• "Top [practice area] firms in [city]"
• "[Partner name]" and "[Partner name] [practice area]"
• "[Your firm] [practice area]"
• "Who should I hire for [specific matter type] in [city]?"

Record whether your firm appears, whether the partner is named and at which firm, and the sources cited. Look for two errors in particular. One is answers saying the partner still works at your firm, which sends clients to the wrong place. The other is answers crediting the new firm with work the partner did at yours.

What should the firm do?

Keep public information accurate

• Do not keep the departed partner listed as current. Beyond confusing clients, it can breach professional rules on misleading communications in regulated professions such as law.
• Replace the old bio URL with a useful page, such as the practice area page, rather than a dead link. A short note that the person has left is fine where your professional rules and agreements allow it.
• Update every profile that names the partner: Google Business Profile, directories, review platform profiles and association listings.
• Follow the notice rules for your profession when clients are told about the move. In law, bar guidance covers how departing lawyers and firms notify clients.

Rebuild evidence around the remaining team

• Publish full bios for the partners and senior staff who remain, with matters, publications, rankings and credentials.
• Rewrite practice pages around the team's collective experience and recent matters, where confidentiality allows.
• Announce new hires and promotions, so recent coverage exists for your firm too.
• Submit to directories for the next research cycle, with referees who can speak to the current team.
• Ask every client, whatever the outcome, for an honest review in their own words, within your profession's rules on testimonials and without suggesting what to write.
• Publish useful content under current partners' names in the practice area, and pursue speaking and press opportunities.

Decide whether the practice area is still a strength

If most of a group left, you may be better served by focusing on the areas where the remaining team is strongest. Chasing recommendations for a capability the firm no longer has will disappoint clients who do call.

Other reasons one competitor suddenly dominates recommendations are covered in why the same competitor suddenly appears in every ChatGPT buyer recommendation.

How long does recovery take?

Assistants that search the web live can reflect updated pages and new coverage within weeks. Answers that rely on a model's training data can lag for months, until a newer model is released. Directory rankings change on their annual or semi-annual cycles. Some recovery within a few months is possible in engines that search live; a fuller one usually needs at least one directory cycle, so plan over a year, and build real evidence around the current team.

What might an illustrative case look like?

Consider an illustrative mid-sized firm whose best-known employment partner leaves for a competitor, taking two associates. Within a month, Perplexity and ChatGPT's search answers to "best employment lawyer in [city]" name the partner at the new firm, citing the lateral move announcement and a directory profile. Gemini still says the partner is at the old firm. The old firm had deleted the bio, and its employment page now says little. It replaces the bio URL with a rewritten employment page listing its three remaining employment partners and their recent matters. It also updates its directory profiles and publishes two articles by the new group head. It announces a lateral hire of its own. Three months later, the firm appears again in some answers, alongside the departed partner's new firm, and Gemini no longer places the partner at the old firm.

What do people ask about partner departures and AI answers?

Can we ask ChatGPT to stop recommending the partner's new firm?

No. If the answers are accurate, there is nothing to correct. Focus on making your own firm's current strengths visible.

Should we keep the departed partner's articles on our site?

Articles can usually stay, attributed accurately, if your agreements and professional rules allow. Make clear the author has left, and avoid implying they are still at the firm.

Does this only affect law firms?

No. Accounting firms, consultancies, agencies and medical practices see the same pattern when a well-known individual leaves.

What if assistants still say the partner works at our firm?

Check where that comes from: often an old directory listing, a cached bio or an outdated association profile. Update those sources, and make sure your own site no longer lists the partner. Clients sent to the wrong firm are a service problem for both firms, so correcting it quickly is in everyone's interest.

Can non-compete agreements prevent this?

Not for AI answers, and in law, restrictions on a lawyer's right to practise after leaving are generally not allowed. The answer is to build firm-level evidence, not to rely on individuals staying.
