You and your partner built this practice together. You split the equity, split the on-call schedule, and signed the practice lease together. Now something has shifted. You are being left out of scheduling decisions. Your access to the practice management system changed without warning. Your paycheck or distribution came in lower than usual, with no explanation attached.
You are asking the question every physician-owner in this position asks: can my partner actually do this? The short answer is no, not without consequences. California law gives physician shareholders real protections against being frozen out of the practice they helped build, and physicians forced out of a medical partnership in California are not without recourse. Those protections only work if you recognize what is happening and act on it in time.
Why This Matters Right Now
A medical practice is not an ordinary small business. Your ownership stake usually represents years of buy-in payments, deferred compensation, and goodwill built through referral relationships and patient trust. When a partner tries to force you out, the practice's revenue, your professional reputation, and your patients' continuity of care are all at stake at the same time.
Most California medical practices with more than one owner-physician are organized as professional medical corporations under the Moscone-Knox Professional Corporation Act, Corporations Code sections 13400 through 13410, which requires that only licensed physicians hold shares in the corporation. That structure matters here. Your partner cannot simply sell your interest to an outside investor or bring in a non-physician manager to work around you, but the leverage points in a freeze-out, meaning board votes, officer titles, corporate bank accounts, and access to the entity’s records, are corporate tools, not personal ones. California lawmakers have also been paying closer attention to who actually controls physician practices. A 2025 law aimed at limiting outside interference with physician decision-making took effect at the start of 2026, a reminder that ownership and control of medical practices are under more legal scrutiny than they used to be.
Is It Legal for My Partner to Cut Me Out of Decisions, Pay, or the Office?
Not automatically, and not without risk to the partner doing it. Whether your partner’s conduct is lawful depends first on your governing documents, meaning your shareholder agreement, corporate bylaws, or partnership agreement, and second on the fiduciary duties California law imposes on the people who control a closely held corporation. Understanding your physician shareholder rights starts with pulling both of those documents out and reading them side by side with what is actually happening.
In a professional corporation with only two or a small handful of physician-shareholders, the majority owner, or owners acting together, owes fiduciary duties to the minority. California courts have recognized that a shareholder in a closely held corporation can bring a direct, individual claim for breach of fiduciary duty when the harm is a disproportionate personal injury, such as being cut out of compensation or distributions at the plaintiff’s specific expense, rather than a generalized harm to the company. This comes from Jara v. Suprema Meats, Inc., a case California business litigation attorneys still rely on today.
That distinction matters because a separate line of cases, including Schrage v. Schrage, holds that claims about money being diverted or misapplied at the corporate level generally have to be brought as a derivative action on behalf of the corporation, not as a personal claim. Bringing the wrong type of claim, or only the wrong type, is one of the more common ways a legitimate claim gets dismissed or delayed early. Getting this distinction right at the pleading stage is exactly where a Los Angeles business litigation lawyer earns their fee.
What Counts as a Physician Partner Freeze-Out or Minority Shareholder Oppression in a Medical Practice?
California recognizes a body of law informally called shareholder oppression, or minority oppression, covering conduct designed to frustrate a minority owner’s reasonable expectations without necessarily breaking a written contract. In a medical practice, this kind of minority shareholder oppression often shows up as a pattern rather than one dramatic event: exclusion from partner meetings where major decisions get made, restricted access to the electronic health record or scheduling system, a sudden and unexplained cut to compensation or distributions, denial of the corporation’s financial statements, or pressure to sign a buyout at a price nobody independently verified.
No single fact on that list always proves oppression by itself. Together, especially when the pattern escalates after you raised a concern or turned down a lowball offer, they build the record that supports both a fiduciary duty claim and, if it gets bad enough, a request for court intervention.
What Are My Legal Options If My Partner Is Trying to Force Me Out of the Practice?
Involuntary Dissolution Under Corporations Code Section 1800
California Corporations Code section 1800 allows qualifying shareholders to petition the superior court to dissolve a corporation. Two grounds tend to show up most often in a physician freeze-out: internal dissension so severe that two or more factions of shareholders are deadlocked and the business can no longer be run to the shareholders’ advantage, and conduct by those in control amounting to persistent and pervasive fraud, mismanagement, abuse of authority, or persistent unfairness toward a shareholder. That last phrase, persistent unfairness, is where most freeze-out fact patterns land.
To bring this action, you generally need shareholders holding at least 33 and one-third percent of the outstanding shares, not counting shares held by those involved in the alleged misconduct, or you need to independently qualify under one of the statute’s other categories. In a true 50/50 practice, you clear that threshold on your own. In a practice with three or more owners, you may need another shareholder on your side, which is one more reason documenting the pattern early matters.
In practice, very few physicians actually want a judge to order their practice liquidated. Dissolution is rarely the real goal. It is leverage. Corporations Code section 2000 gives the corporation, or the shareholders who are not seeking dissolution, the right to avoid dissolution entirely by electing to buy out your shares at fair value instead. If the parties cannot agree on a number, the statute provides for a court-supervised appraisal using disinterested appraisers. Filing, or credibly threatening to file, a section 1800 petition is often what moves a partner from a lowball verbal offer to a real negotiation over what your interest in the practice is actually worth.
Can We Resolve This Medical Practice Buyout Dispute Without Going to Court?
Often, yes, and it is usually the better outcome for everyone, including your patients. Most freeze-out disputes end in a negotiated buyout rather than a dissolution trial. The starting point is always your governing documents. If your shareholder agreement or bylaws include a buy-sell provision, a valuation formula, or a mandatory mediation or arbitration clause, that language controls the process and often the price.
Where the documents are silent, outdated, or were never properly put in place, which is common in practices that formed quickly around a handshake, the fair value standard under Corporations Code section 2000 becomes the practical benchmark, informed by the same going-concern and liquidation analysis a court-appointed appraiser would use. Getting an independent valuation of the practice, including its receivables, equipment, lease value, and goodwill, before you respond to any buyout number your partner proposes is one of the more protective steps available to you. If your first move is to counter a number with another number instead of your own valuation, you have likely already given away leverage.
What Not to Do When a Partner Is Trying to Force You Out of a Medical Partnership in California
A few reactions feel natural in the moment and tend to make things worse.
Do not sign a buyout agreement, resignation letter, or amendment to the shareholder agreement without your own attorney and your own valuation. A number that feels generous compared to nothing is not the same as fair value.
Do not walk away from the practice or stop showing up for scheduled duties, even if you feel unwelcome. Abandoning your role can undercut your own position and, in an extreme case, hand your partner an abandonment argument under the very dissolution statute you might otherwise use.
Do not take patient records, practice funds, equipment, or referral lists on your way out the door, even if you believe you are entitled to a share of them. That conduct can expose you to the same fiduciary duty claims you are trying to bring against your partner, and it can hand the other side a justification for what they already did.
Do not wait to see if things settle down. Freeze-out patterns tend to escalate, and financial harm compounds with every pay period you go without full compensation. Several of the claims available to you, including fraud and breach of fiduciary duty, run on filing deadlines that start from the date you discovered the conduct, whether or not you decided to act on it right away.
Documents to Gather Before You Call an Attorney
Pull together as much of the following as you can before your first consultation. It will speed up the analysis of what claims you have and what your interest in the practice is actually worth.
- Your shareholder agreement, buy-sell agreement, corporate bylaws, or partnership agreement, along with any amendments
- Articles of incorporation and any board or shareholder meeting minutes from the past two to three years
- Compensation, distribution, and payroll records, including K-1s or W-2s, going back at least three years
- The corporation’s financial statements, tax returns, and bank records, or documentation of your written demand to see them if access has been denied
- Any written buyout offer or proposed valuation you have received
- Emails, texts, or messages documenting decisions made without you, changes to your system access, or statements about your role in the practice
If your partner has already refused to let you see the corporation’s books, that refusal is itself worth documenting. California law generally gives a shareholder the right to inspect corporate records for a purpose reasonably related to their interest as a shareholder, and a documented denial can become part of your case.
When Should I Bring in an Attorney?
Sooner than feels necessary. If your partner has physically or electronically locked you out of the office or the practice’s systems, stopped or reduced your pay without a documented reason, proposed a buyout without giving you time or access to information to evaluate it, or started making major decisions such as hiring, leases, or loans without your input despite your ownership stake, those are signals the situation has moved past something you can resolve over a conversation.
The earlier a business litigation attorney gets involved, the more options are usually still on the table, from a demand letter and negotiated buyout to emergency relief if the practice’s assets or patient care are genuinely at risk.
The Takeaway
Being frozen out of a medical practice you helped build is not something California law simply allows to happen. Physician shareholders have fiduciary duty protections, a real path to court-ordered dissolution under Corporations Code section 1800 when the conduct is bad enough, and a strong incentive structure under section 2000 that usually pushes freeze-out disputes toward a fair negotiated buyout instead. The physicians who come out of these situations best are the ones who document the pattern early, get an independent valuation before responding to any offer, and bring in counsel before signing anything.
