Regulated acquisition guide
Buying a professional practice in New York
Veterinary, dental, accountancy, pharmacy, medical: these look like ordinary small businesses until you try to buy one. Two features of New York's regime change the transaction, and both are better understood before the letter of intent than after.

Who is allowed to own it
The clearest statement of the rule sits in an unglamorous place: the filing instructions for amending a New York professional corporation. A Certificate of Amendment requires an "Attestation signed by President listing all current shareholders, officers, and directors, signed under penalties of perjury. Professional license numbers and residence addresses must also be listed" [1] .
Look at what the form takes for granted. Every shareholder has a licence number. So does every officer, and every director. There is nowhere on it to describe an owner who is not licensed, because the structure does not contemplate one.
One documented exception: public accountancy. The Office of the Professions publishes a form headed "Application for Public Accountancy Firm Registration or Amendment to add Non-Licensee Owners to Existing Firms" [4] . A published form for the arrangement means the route is recognised rather than improvised. What conditions attach — proportions, control, roles, attest work — is a question for the Department and for counsel. If you are an unlicensed buyer, see buying an accounting practice. Do not read the exception across to the other professions; it is specific to this one.
So for a buyer the first question is not what the practice is worth. It is whether you are eligible to hold it.
| If you are… | What is available |
|---|---|
| Licensed in the profession | The ordinary route. You can become a shareholder, and the transaction is a corporate change requiring the filings below |
| Licensed in a related profession | Sometimes permitted between specified professions, sometimes not. This is precisely the kind of question to put to counsel rather than assume either way |
| Not licensed | Not the practice itself. What can be acquired is the surrounding business — premises, equipment, systems, non-clinical staff — with the regulated services provided by a licensed professional or entity under contract |
On that third row, a caution rather than a recipe. Arrangements separating the regulated practice from the business around it are common and can be entirely proper. They are also constrained by rules on fee-splitting and on the corporate practice of the professions, they are highly fact-specific, and they are scrutinised. This page tells you the arrangement exists so you know what you are asking about. It does not tell you how to build one, and no web page should.
Industry guides applying this framework: veterinary practices, dental practices, pharmacies and medical practices.
The timetable people do not budget for
The second feature is procedural, and it is the one that moves closing dates.
A professional entity change requires a Certificate of Authority from the Office of the Professions, and the Department states this "can only be applied for through the mail", with the fee paid by check or money order. It then asks filers to "allow 8-10 weeks for the Office of the Professions to review your application" [1] .
And the review is one step of three, across two agencies:
| Step | Who | What moves |
|---|---|---|
| 1 | Office of the Professions | Application by post with the corporate document, contact form, attestation and fee. Allow 8–10 weeks. A Certificate of Authority comes back by post |
| 2 | Department of State | Submit the Certificate of Authority with the corporate document and fees, specifically requesting a certified copy back — the instructions call that out, which suggests people forget |
| 3 | Office of the Professions | Post the certified copy back with a further fee to complete registration |
Three exchanges. Two agencies. By post. With an 8–10 week review before any of it starts. A closing date set without that in it is a closing date that will move. See how long it takes to buy a business for where this sits against everything else.
An SBA rule that bites harder here
If you are financing with a 7(a) loan, note the interaction with a rule covered in our equity injection guide: on a Business Expansion or Initial Acquisition, the seller may not remain as an officer, director, stockholder or employee, and a consultancy is capped at 24 months in aggregate [3] .
In most industries that is manageable. In a practice built on a practitioner's personal relationships it is the central tension of the deal: the thing that would most protect your investment — the selling professional staying on indefinitely — is the thing the financing forbids. Plan the transition inside 24 months, and price the practice on what survives the end of it.
What you are actually buying
Set the regulatory questions aside and the valuation question in a practice is unusually stark: does the patient, client or customer come to the practice or to the person?
- Get the book by practitioner, not in total. Revenue, active file count, and how much of it is attributable to anyone leaving.
- Establish how new work arrives. Referral from other professionals is a relationship that may be personal. Search, insurance panel listing or location is a channel that transfers.
- Read the practitioner agreements. Are the other licensed professionals employed, contracted, or partners? What notice do they have, and what restrictions apply on departure?
- Check the entity's standing at the Department of State before relying on how the seller describes it [2] .
- Confirm every practitioner's licence and registration status at source. A lapsed registration is a live operating problem, not paperwork.
- Understand the records obligation. Professional records carry retention requirements and transfer protocols, and they are an obligation you inherit as well as an asset you receive.
Our concentration guide covers the framework; here the concentration is almost always a practitioner rather than a client.
Before the letter of intent
- Establish your own eligibility. Everything else is contingent on it.
- Confirm the entity form — P.C., PLLC, partnership or something else — because the filing path differs.
- Put the 8–10 week review into the timetable before you agree dates, not after.
- Ask what the selling professional will do, and reconcile the answer with the SBA 24-month consultancy cap if you are borrowing.
- Get counsel who does this specific profession, not general transaction counsel alone. The rules vary by profession and the general shape described here is a starting point rather than an answer.
Scope and limits
This describes the general New York framework for professional entities as the Office of the Professions publishes its filing requirements, and the timetable those requirements imply. Individual professions have their own rules on ownership, supervision, advertising, records and fee arrangements, and this page does not set out any of them. It does not address federal healthcare regulation, insurance panel participation, or the many profession-specific consents an acquisition may need. A professional practice acquisition needs counsel who practises in that profession's regulatory area, engaged early.
Frequently asked questions
Can I buy a professional practice if I am not licensed in that profession?
Not as a shareholder of the professional corporation. A Certificate of Amendment for a New York P.C. requires an attestation, signed by the president under penalties of perjury, listing all current shareholders, officers and directors together with their professional licence numbers and residence addresses. There is no line on that form for an unlicensed owner. There is one documented exception worth knowing: public accountancy, where the Office of the Professions publishes a form expressly headed as an application for firm registration or amendment to add non-licensee owners to existing firms. Outside that, if you are not licensed, the practice itself is not something you can hold.
So how do unlicensed buyers acquire these businesses?
Generally by buying the assets that are not the practice — premises, equipment, systems, non-clinical staff — and contracting with a licensed professional or professional entity that provides the regulated services. These arrangements are common, heavily fact-specific, and constrained by rules on fee-splitting and the corporate practice of professions. This is genuinely specialist legal work and not something to structure from a web page.
How long does the Office of the Professions take?
The Department asks filers to allow 8 to 10 weeks for the Office of the Professions to review a Certificate of Authority application, and the application can only be made by mail. That is before the Department of State step. Build it into the closing timetable rather than discovering it after you sign.
Is it really a mail-only process?
For the Certificate of Authority, yes — the Office of the Professions states it can only be applied for through the mail, with the fee paid by check or money order. In a process where the buyer's clock is already 8 to 10 weeks, a posted application and a posted response are not a detail.
What is the two-step filing?
First the Office of the Professions issues a Certificate of Authority. Then you submit that Certificate together with the corporate document to the Department of State, requesting a certified copy back. Then you send the certified copy and a further fee back to the Office of the Professions to complete registration. Three exchanges, two agencies, by post.
Which practices does this cover?
The professions licensed by the New York State Education Department's Office of the Professions, which include medicine, dentistry, veterinary medicine, pharmacy, public accountancy, engineering, architecture, nursing and many others. If the business you are buying provides services that require a state professional licence, assume this framework applies and check.
Does an asset purchase avoid the problem?
It changes it rather than avoiding it. You can buy assets without becoming a shareholder of the P.C., but you still cannot lawfully provide the professional service yourself unless licensed, and the practice's value usually rests on that service continuing. The structure question and the licensing question have to be answered together, with counsel.
