Professional Medical Corporations in California
California physicians who want to practice as a corporation generally use a professional medical corporation, not a standard business corporation. Medicine is a licensed profession. Ownership, control, and clinical decision-making are tied to licensure. A professional medical corporation lets you hold practice assets, sign leases and vendor contracts, hire staff, and share ownership with other eligible licensees, while keeping the practice under professional control.
We advise on forming these entities, documenting ownership, and handling the contracts and disputes that follow as a practice grows, adds partners, or separates. This is the kind of counseling we provide as outside general counsel to a closely held professional business.
What Professional Medical Corporations Involve
Professional medical corporations are the legal structure for a physician-owned medical practice that operates as a corporation. The work focuses on who may own the entity, how decisions get made, how money and risk are allocated, and how the corporation contracts with employees, landlords, and vendors.
Formation work typically includes the articles of incorporation, bylaws, initial organizational approvals, and the issuance of shares to eligible licensed owners. Shareholder agreements address voting, officer authority, compensation, transfer restrictions, and what happens if a physician retires, becomes disabled, loses a license, or wants to leave.
A professional medical corporation is both a professional practice and a small business. It signs employment agreements, independent contractor arrangements, office leases, equipment contracts, and service agreements with billing companies, laboratories, and other vendors. We draft and negotiate those contracts so obligations sit with the entity, and so clinical control is not handed to an unlicensed party by accident.
When physicians disagree about compensation, control, or a buyout, the documents and the facts control the options. Many of these disputes resolve through negotiation or mediation. David Chapman is a certified mediator. If a dispute does not resolve, it may proceed as civil litigation, like other closely held business cases.
Why Professional Medical Corporations Matter to Clients in California
California restricts the corporate practice of medicine. People and companies that are not licensed to practice medicine generally cannot own a medical practice or control clinical decisions. That policy is meant to keep medical judgment with licensed professionals. It also decides which business forms you can use, who can buy shares, and which contract terms are workable.
A professional medical corporation is the usual California vehicle for physicians who want an entity that can own property, employ staff, and hold contracts. It is not a general business corporation. It is also not the professional limited liability company used in some other states.
The structure matters as soon as a second physician, a spouse, a manager, or an outside company becomes involved. Lay investors, unlicensed family members, and purely financial owners often cannot hold shares. A management company may provide nonclinical services such as billing, human resources, or office administration. It generally cannot dictate diagnosis, treatment, or other medical judgments. Getting that line wrong can create licensing problems, weak contracts, and a fight over who owns and controls the practice.
These rules are statewide. Formation filings go to the California Secretary of State. Licensing and practice-name issues are handled through the state medical licensing board. Leases, bank accounts, payer arrangements, and vendor agreements are often in the name of the professional medical corporation, so ownership papers and signing authority affect daily operations as well as later buy-ins and departures.
Common Issues Clients Face
Physicians and medical groups tend to meet the same pressure points with professional medical corporations, even when the facts differ.
- Starting a practice before a lease is signed or staff are hired, including who will own shares and whose name will appear on contracts.
- Adding a partner, including whether shares are purchased or granted, how compensation and call will work, and what happens if the relationship fails.
- Departure, retirement, disability, or death, when shares cannot be freely sold and no one agrees on price, accounts receivable, insurance, or the office lease.
- Disputes over production formulas, part-time schedules, signing authority, and hiring.
- Use of a clinic name that is not the shareholders' legal names, which often requires extra steps with the medical licensing board.
- Requests from a spouse, investor, or management company for shares or veto rights that may conflict with licensed-ownership rules.
- A shareholder who can no longer hold a required license.
- Combining two groups, or splitting one group, including leases, equipment, and continuity of patient care.
How a Client Typically Gets From Problem to Resolution
The path depends on whether the task is a new professional medical corporation, an ownership change, or an existing dispute.
For a new professional medical corporation, the proposed owners, their licenses, and the planned split of voting power and profits are identified first. A corporate name is selected with professional naming rules in mind. Formation documents are prepared and filed with the California Secretary of State. Once the entity exists, the owners adopt bylaws, issue shares, and sign a shareholder agreement. Related contracts, such as physician employment agreements and the office lease, are aligned with the corporation. Tax classification and payroll are coordinated with your accountant. Legal work does not replace that tax and bookkeeping work.
For an ownership change, the parties agree on price or a valuation method, payment terms, any continuing employment, and how insurance, accounts receivable, equipment, and the lease will be handled. Those terms are written into a purchase or redemption agreement and reflected in the share records and corporate approvals.
For a conflict, the existing articles, bylaws, shareholder agreement, and employment contracts are reviewed first. Those papers often already set a process for deadlock, buyout, or dissolution. Many physician-owner disputes resolve through direct negotiation or mediation. If they do not, the dispute may proceed in civil court. Professional licensure and patient care continuity still affect the practical options, even when the claims look like a standard business fight. Past matters do not predict the next one.
Key Legal Considerations
Shares in a professional medical corporation are generally limited to people licensed in the profession. In some group settings there is only narrow room for other licensed healing arts professionals. Directors and officers are typically licensed as well. A promise of equity to a practice manager, investor, or unlicensed family member often cannot be carried out in the form people expect.
A corporation can help separate ordinary business debts from personal assets when the entity is real, with its own accounts, records, and contracts. It does not erase professional responsibility for your own care of patients. Malpractice coverage is a separate issue from the corporate form. Personal guarantees on leases and loans are also common, so the corporate form is not a complete shield.
Share transfers are usually restricted. Many shareholder agreements set a valuation method, a buyout process, and rules for retirement, disability, death, or loss of license. Handshake deals among colleagues are a frequent source of later litigation. Compensation, part-time work, outside activities, expense allocation, and signing authority are easier to manage when they are written down while the relationship is still good.
Billing companies, landlords, hospitals, and management services organizations can support a practice. Contract terms that give a nonphysician veto over clinical hiring, professional fees, or treatment create risk. A departing physician and the corporation still have to deal with medical records and continuity of care. Formation work also touches insurance, banking, credentialing, and tax elections. Inconsistent paperwork among those items can create later problems.
