A plastic surgery partnership that made sense when you signed the papers can become one of the most complex and financially consequential disputes in California business law. The stakes are high because the business itself is high-value: a plastic surgery practice generating $2 million or more in annual revenue with established patient relationships, surgeon reputation, and branded goodwill can be worth multiples of that revenue to the right buyer or exiting partner. When the partnership breaks down, the question of how that value is divided, who gets the patients, what happens to the surgical schedule, and whether either surgeon can open nearby becomes a dispute that can take years to resolve and millions of dollars off the table.
California’s corporate practice of medicine doctrine adds a layer that most business dissolutions do not face. A plastic surgery practice must be owned through a professional medical corporation under the Moscone-Knox Professional Corporation Act, codified at Corporations Code sections 13400 through 13410. Shares cannot be transferred to non-physicians. When a partner exits, the shares must be acquired by a licensed physician or redeemed by the corporation itself within 90 days of the partner becoming disqualified or departing. A dissolution that ignores those rules does not just produce a bad business outcome. It can produce Medical Board exposure and regulatory consequences that follow both surgeons long after the practice is gone.
This guide explains how California law governs the dissolution of a plastic surgery practice partnership, what determines who walks away with what, where the most expensive mistakes happen, and how to structure an exit that protects your financial interest, your patient relationships, and your professional standing.
Why Plastic Surgery Partnership Dissolutions Are Different
Most business partnership dissolutions are primarily financial events. A plastic surgery dissolution is that, but it is also a clinical event, a patient-relationship event, and a reputation event in a specialty where referrals are personal and word travels fast in the Los Angeles surgical community.
The Practice Is Worth More Than the Books Show
Plastic surgery practices are typically valued using an income approach based on Adjusted EBITDA, earnings before interest, taxes, depreciation, and amortization, normalized for owner-specific expenses and one-time costs that would not recur under new ownership. A practice with $3 million in collections and $600,000 in Adjusted EBITDA might trade at a multiple of four to six times that figure in the current market, placing its enterprise value between $2.4 million and $3.6 million, or higher if the practice has strong recurring aesthetic revenue from injectables, skincare, or an attached med spa operation.
That number is not what most partners carry in their heads when a dispute starts. They think about the tangibles, the equipment, the lease, the inventory. The tangibles are a fraction of the value. The majority of a plastic surgery practice’s value is intangible: goodwill, brand, patient relationships, staff, and the revenue those assets generate. And goodwill in a plastic surgery practice comes in two forms that carry very different legal consequences.
Personal Goodwill Versus Enterprise Goodwill
Personal goodwill is the value tied to an individual surgeon’s reputation, technique, and patient relationships. It moves with the surgeon. If the departing partner built the rhinoplasty reputation that drives 60 percent of consultations, much of that value will walk out with them. Enterprise goodwill is the value tied to the practice itself: its brand name, its systems, its location, its staff, its payor contracts, and its aesthetic services that generate revenue independent of any single surgeon.
This distinction matters enormously in a dissolution because personal goodwill is generally not compensable to the remaining partner. A departing surgeon cannot be required to transfer their personal reputation, their patient relationships, or their surgical skills as part of a buyout. Enterprise goodwill, by contrast, belongs to the professional corporation and must be valued and allocated in any legitimate dissolution or buyout. When the partners disagree about how much of the practice’s value is personal versus enterprise goodwill, they are really disagreeing about the buyout price, and that disagreement frequently ends up in court.
Patients Have the Right to Choose Their Surgeon
Under California law and Medical Board standards, patients cannot be treated as practice assets that automatically stay behind when a surgeon leaves. Patients have the right to continue care with the surgeon of their choice. Both departing and remaining partners have an obligation to notify patients of the change in the practice structure, provide information about each surgeon’s continued availability, and ensure patient records are accessible regardless of which surgeon the patient chooses.
HIPAA governs how patient records are handled during a practice transition. The Medical Board of California expects that patients receive reasonable advance notice, access to their records, and continuity of care. A dissolution that fails to address patient notification properly creates regulatory exposure on top of the business litigation. A dissolution that tries to prevent patients from following the departing surgeon is almost certainly going to fail, and may create additional legal claims in the process.
How California Law Governs the Dissolution of a Medical PC Partnership
A plastic surgery practice operating as a professional medical corporation is governed by the Moscone-Knox Act alongside California’s general corporation law. The dissolution of such an entity, whether voluntary or involuntary, follows a specific legal framework.
Voluntary Dissolution With a Buy-Sell Agreement
If the practice has a well-drafted shareholder agreement or buy-sell agreement, that document governs most of what happens when a partner exits. A good buy-sell agreement specifies the triggering events that require a buyout, the valuation methodology, the timeline for completing the purchase, who is required to buy and who is required to sell, and how the transaction is funded.
The valuation methodology is the most important provision in a physician buy-sell agreement, and it is the one most commonly left vague or set at a stale fixed price that was never updated. A formula-based approach using a multiple of trailing Adjusted EBITDA is objective and predictable. A fixed price set five years ago, never revisited, produces either a windfall or an injustice depending on which direction practice revenues moved. If the buy-sell agreement does not specify a methodology, the parties must negotiate one at the worst possible moment, when trust has broken down and interests have fully diverged.
Involuntary Dissolution When No Agreement Exists or Fails
When partners cannot agree on voluntary terms, California Corporations Code section 1800 provides the pathway to involuntary dissolution. A shareholder holding at least one-third of the outstanding voting shares can petition the superior court for dissolution on grounds including deadlock among directors, internal dissension so severe that the business can no longer be conducted to the advantage of all shareholders, or persistent fraud, mismanagement, or unfairness by those in control.
Filing for dissolution does not mean the practice will actually be dissolved. Under Corporations Code section 2000, the remaining shareholders, or the corporation itself, can elect to purchase the petitioning shareholder’s shares at fair value and thereby avoid dissolution entirely. The court appoints independent appraisers if the parties cannot agree on price, and their determination of fair value is binding. Fair value under section 2000 is the proportionate going-concern value of the corporation, not a discounted liquidation figure. That distinction is significant: fair value in a plastic surgery context captures the goodwill, the brand, and the practice’s earnings power, not just the depreciated value of the surgical equipment and leasehold improvements.
The involuntary dissolution and buyout election process is one of the most powerful tools available to a minority shareholder who believes they are being frozen out or treated unfairly. The threat of filing a section 1800 petition, and the court-supervised valuation that follows if it is filed, frequently produces a negotiated resolution that informal demands do not. Our post on shareholder buyout disputes in California covers these mechanics in detail.
The 90-Day Share Transfer Requirement
Under the Moscone-Knox Act and Corporations Code section 13407, a professional medical corporation must ensure that shares are not held by disqualified persons, meaning non-physicians or physicians whose licenses have been revoked or suspended. When a surgeon-partner departs, retires, loses their license, or otherwise becomes a disqualified holder, the corporation has 90 days to redeem or transfer those shares to a qualified physician. Failure to comply can cause the corporation to lose its professional corporation status, which jeopardizes its ability to operate as a licensed medical practice at all.
A dissolution strategy must account for this timeline. If the departing surgeon holds shares and the remaining partner cannot complete a buyout within 90 days, the practice needs a plan, whether that means identifying a third physician-buyer, structuring a bridge arrangement, or pursuing expedited court proceedings in a contested situation. The regulatory clock runs whether or not the business dispute is resolved.
Where Valuation Battles Are Won and Lost
Valuation is the center of gravity in almost every plastic surgery partnership dissolution. Both sides hire experts. Both experts use legitimate methods and arrive at very different numbers. Understanding what drives those differences helps you prepare for the fight and avoid the mistakes that hand your partner a valuation advantage.
Provider Dependency Is the Largest Valuation Risk
A plastic surgery practice where one surgeon generates 80 percent of revenue is valued far more conservatively than one with diversified provider production. The departing surgeon’s goodwill argument, that the practice’s value is mostly personal and therefore not compensable to the remaining partner, is strongest precisely when the revenue is most concentrated. The remaining partner’s counter-argument, that the brand, systems, location, and staff represent durable enterprise value that will survive the departure, is strongest when the practice has associate surgeons, robust non-surgical revenue, and documented patient retention that does not depend on a single provider.
If you are the remaining partner in a high-concentration practice, your valuation argument needs to account for transition risk honestly. An appraiser who ignores the possibility that patients will follow the departing surgeon will produce a number that opposing counsel and a court will reject. Building a credible valuation means showing what the practice can realistically earn after the departure, with a well-planned transition, rather than assuming nothing changes.
Accounts Receivable, Work in Progress, and Pre-paid Deposits
Plastic surgery practices often carry significant pre-paid surgical deposits from patients scheduled weeks or months out. When a partnership dissolves, the allocation of those deposits, the treatment of outstanding receivables, and the accounting for procedures that have been scheduled but not performed are all contested. A patient who paid a deposit for a procedure with the departing surgeon has a specific expectation. If that surgeon is leaving, the patient has the right to a refund or to follow the surgeon to their new practice. Neither partner can simply retain those deposits as a windfall.
Work in progress and accounts receivable also require careful allocation in any dissolution. California’s Medical Board and HIPAA both impose obligations on how patient financial information and outstanding balances are handled during a practice transition. The financial terms of a dissolution must account for all of these moving parts, not just the valuation of the enterprise as a going concern.
Equipment, Lease, and Facility Agreements
High-end plastic surgery practices often operate out of surgical suites with significant equipment investments: operating room equipment, imaging systems, laser platforms, and aesthetic devices. These assets have book values that rarely match their fair market value, and lease agreements for surgical space may have substantial remaining terms and personal guarantee provisions. The dissolution must address who assumes the lease, how equipment is valued and divided or sold, and how personal guarantees on facility agreements are unwound or reallocated.
If the practice operates its own ambulatory surgery center or in-office surgical suite licensed by the California Department of Public Health, the licensing implications of a change in ownership or operational control require separate attention. A surgical facility license does not automatically transfer as part of a practice dissolution.
The Non-Compete Question: What You Can and Cannot Do in California
Every plastic surgery dissolution eventually gets to the question of whether the departing surgeon can open a practice nearby. The answer under California law is almost always: yes, they can, and most non-compete clauses in physician employment or partnership agreements are void.
Business and Professions Code section 16600 voids any contract that restrains a physician from practicing their profession. Courts have applied this rule consistently to plastic surgeons, and the 2024 enactment of SB 699 added a private right of action and fee-shifting provision that makes attempting to enforce a void non-compete legally dangerous for the party trying to use it.
The sale-of-business exception under section 16601 is the only meaningful tool available. When a departing surgeon sells their ownership interest in the professional corporation, a reasonable geographic covenant tied to the goodwill being transferred may be enforceable. The covenant must be reasonable in scope, must genuinely relate to the goodwill being sold, and must be part of a transaction that constitutes a real sale of a business interest rather than simply an employment termination dressed up as an ownership transfer.
The practical implication is that how the exit is structured determines whether any restriction on the departing surgeon is enforceable. A buyout properly documented as a sale of goodwill under section 16601 gives the remaining partner the best available protection. A dissolution that does not involve a true ownership transfer gives almost none. Our post on non-compete clauses in California medical practices covers the full legal framework, including the 2024 and 2026 changes that affect physician practice exits.
Your Obligations to Patients During the Dissolution
The Medical Board of California expects plastic surgery practice partners to handle a dissolution in a way that does not abandon or harm patients. These are not aspirational standards. They are enforceable professional obligations that run alongside and independently of the business litigation.
Both surgeons are responsible for ensuring that active patients, meaning those with upcoming appointments, scheduled procedures, or active post-operative care, receive reasonable advance notice of the practice transition. Patients must be given the information they need to choose their surgeon, transfer their records, and obtain continuity of care. A patient in an active post-surgical recovery period cannot simply be handed a notice and told to find another physician.
HIPAA requires that patient records be accessible regardless of the dispute between the partners. Patient records belong to the patients, not to either surgeon individually or to the professional corporation. A dissolution plan that contemplates one partner retaining physical control over patient records as leverage in the business dispute is a HIPAA violation and a Medical Board complaint waiting to happen.
California Health and Safety Code section 123111 gives patients the right to inspect and receive copies of their records within defined timeframes. The dissolution plan must include a records custodian arrangement that functions during the transition, not just after it is complete. Both parties benefit from clear documentation of how this was handled, because a Medical Board investigation arising from a patient complaint during a dissolution dispute makes an already complicated situation significantly worse.
Steps to Take When Dissolution Becomes Likely
The decisions made in the weeks before formal legal proceedings begin often determine how much leverage each party has once the dispute becomes adversarial. These are the steps that protect your position before the litigation clock starts running.
Pull every governance document the practice has. Your shareholder agreement, buy-sell agreement, corporate bylaws, employment agreements, facility leases, equipment financing agreements, and the Management Services Agreement if you operate with an MSO structure: all of these contain provisions that will govern what happens next. Review them before your partner does, so you understand your rights and obligations before you take any action that could be used against you.
Do not take unilateral action with practice assets. Do not transfer equipment, move patient records, redirect practice revenue, or make unilateral changes to the banking arrangements while a dispute is developing. Unilateral asset moves in a dissolution dispute generate independent legal claims and undermine your credibility in the underlying valuation fight. Get legal counsel before taking any significant action with practice assets or operations.
Document the practice’s financial performance contemporaneously. The valuation date in a court-supervised dissolution is typically the date the petition is filed, or another date the court designates on good cause. Your ability to present accurate, credible financial records for the practice through that date directly determines the quality of the appraisal your expert can produce. Gaps in financial records, or records that reflect significant owner distributions made in anticipation of a dispute, create vulnerabilities that opposing counsel will exploit.
Engage business litigation counsel with experience in medical practice dissolutions before you begin any formal negotiation. A general business attorney who does not understand the Moscone-Knox Act, the 90-day share transfer rule, the personal versus enterprise goodwill distinction, and the Medical Board’s role in a physician dissolution will miss the issues that make these disputes different from standard corporate dissolutions. The intersection of healthcare regulation and business litigation requires both.
Frequently Asked Questions
Plastic surgery practices are typically valued using an income approach based on Adjusted EBITDA, normalized for owner expenses and one-time costs. That figure is multiplied by a market-based multiple reflecting the practice’s risk profile, revenue diversity, and provider dependency. The distinction between personal goodwill (tied to the individual surgeon and generally not compensable to the remaining partner) and enterprise goodwill (tied to the practice’s brand, systems, and recurring revenue) significantly affects the final number. In a contested dissolution, the court appoints independent appraisers under Corporations Code section 2000 if the parties cannot agree.
Generally no, unless the exit is structured as a genuine sale of ownership interest and goodwill under Business and Professions Code section 16601. California voids most non-compete clauses for physicians under section 16600, and attempting to enforce a void clause exposes you to a fee-shifting claim from your former partner under SB 699. How the exit is documented determines whether any restriction is enforceable. A properly structured buyout of goodwill gives you the best available protection; a dissolution without a true ownership transfer gives you almost none.
Patients have the right to continue care with the surgeon of their choice. Both partners have Medical Board obligations to notify active patients of the transition, provide records access, and ensure continuity of care. Patient records cannot be used as leverage in the business dispute. A failure to handle patient notifications and records access properly during a dissolution can generate Medical Board complaints that run alongside and independently of the business litigation.
Under Corporations Code section 1800, a shareholder holding at least one-third of voting shares can petition for involuntary dissolution on grounds of deadlock, internal dissension, or fraud and mismanagement. If that petition is filed, you as the remaining shareholder can elect under section 2000 to purchase the petitioning partner’s shares at court-determined fair value, which avoids dissolution and allows the practice to continue. The strategic deployment of this election, with experienced litigation counsel, often produces a negotiated resolution that preserves the practice.
Yes, if a physician-partner departs, retires, loses their license, or otherwise becomes disqualified from holding shares in the professional medical corporation. Under the Moscone-Knox Act and Corporations Code section 13407, shares held by a disqualified person must be transferred or redeemed within 90 days. Failure to comply can jeopardize the corporation’s professional status. A dissolution plan must account for this timeline regardless of whether the business dispute is resolved within that window.
In most cases, yes. A plastic surgery partnership dissolution that proceeds to full litigation involves appraiser fees, attorney’s fees, depositions of both surgeons, and a disruption to the practice’s operations that destroys value for both parties. Mediation with an experienced healthcare business mediator, undertaken with both parties represented by counsel, frequently produces an economically superior outcome compared to full litigation. The threat of litigation, particularly the section 1800 involuntary dissolution petition and section 2000 buyout election, provides the leverage that brings reluctant parties to the mediation table.
Exit on Your Terms, Not Your Partner’s
A plastic surgery practice partnership dissolution is one of the highest-stakes business disputes California law handles. The financial value at risk, the regulatory obligations that run alongside the commercial dispute, and the speed at which unresolved conflicts destroy practice value all require experienced legal strategy from the moment a dissolution becomes likely, not after one party has already made moves that cannot be undone.
