Building an Internal Succession: Bringing in a Partner or Associate to Take the Reins

Buy-Sell Agreements, Shareholder Structures, and the Art of the Internal Transition

For many California healthcare providers, the ideal succession is not a sale to a stranger. It is a transition to someone already inside the practice — a trusted associate, a younger physician, a dental partner who already knows your patients, your staff, and the way you run things. Done well, an internal succession preserves the culture of the practice, protects patient continuity, and gives the departing provider the satisfaction of watching what they built continue in capable hands.

Done poorly — or not at all — it becomes one of the most expensive disputes in healthcare law.

Why California Makes Internal Succession Structurally Demanding

Internal succession in a California healthcare practice is not simply a matter of adding someone's name to the door. Because only licensed professionals may own a California professional medical or dental corporation (Corporations Code Section 13401.5), every ownership transition must be structured carefully within the Moscone-Knox Professional Corporation Act framework.

The most critical document in any internal succession is the buy-sell agreement — also known as a shareholder agreement. California's own professional corporation compliance resources describe the buy-sell agreement as essential for “the orderly continuation and transfer of a professional practice,” noting that without one, the transfer of shares may be impossible to accomplish in a structured manner because shares in a professional corporation “cannot be held or owned by a non-licensed individual.”

Under Corporations Code Section 13406.5, if a shareholder dies or becomes disqualified, the corporation must acquire those shares within six months of death or 90 days of disqualification. Without a buy-sell agreement establishing a valuation method and a mechanism for that acquisition, the corporation — and its license — are placed at immediate risk.

The Associate-to-Partner Track: Planning the Transition in Advance

The most common internal succession model begins with hiring an associate physician or provider with the explicit, documented intent that they will eventually purchase an ownership interest. This approach allows the departing provider to:

•      Evaluate the associate's clinical quality, patient relationships, and business judgment before committing to a transition

•      Allow the associate time to build equity and secure financing

•      Gradually shift patient and referral relationships to the incoming provider

•      Reduce dependence on the departing provider's personal goodwill over time — increasing the practice's enterprise value

The key legal documents required at each stage:

At hiring: An employment agreement that clearly addresses whether the associate has any option or right to purchase ownership, any non-compete provisions (narrowly drafted under BPC Section 16600, or structured as a sale-connected non-compete under BPC Section 16601 if an ownership purchase is anticipated), and compensation structure.

At the option stage: A documented option or letter of intent specifying valuation methodology, timeline, and conditions to closing. Ambiguity at this stage is the most common source of associate-to-partner disputes.

At closing: A formal stock purchase agreement and amended shareholder agreement, compliant with the Moscone-Knox Act, reflecting the new ownership structure, buy-sell provisions for both parties, and any seller financing terms.

Valuing the Ownership Interest in an Internal Transition

Internal transitions frequently fail at the valuation stage — not because the parties cannot agree on a number, but because they never agreed on a method for arriving at one. California healthcare practice appraisal experts identify several common methodologies:

Capitalization of earnings — the most commonly used method for medical and dental practices. It applies a multiplier to normalized EBITDA or net income to arrive at enterprise value. The appropriate multiplier varies significantly by specialty, payer mix, geography, and market conditions.

Book value plus goodwill — applies the balance sheet value of hard assets plus an agreed-upon goodwill premium. Simpler but often less accurate, particularly for practices with significant intangible value.

Revenue multiple — applies a practice-specific multiplier to gross annual collections. Common in dental practice transactions. Less reliable for medical practices with complex payer mixes.

Pre-agreed formula — the most practical approach for buy-sell agreements. The parties agree, at the time the agreement is executed, on the formula that will be used to value the shares when a triggering event occurs. This removes the valuation dispute entirely from the triggering event — which is often a death, disability, or conflict, a terrible time to negotiate.

Benefits of pre-agreed valuation formula: Certainty. Speed. Dramatically reduced litigation risk. The value is known before the crisis, not determined during it.

Drawbacks: A formula agreed upon years ago may not reflect current market conditions. Build in a periodic review mechanism — ideally every three years.

Funding the Buy-Out: How the Departing Provider Gets Paid

The internal succession plan is only as good as its funding mechanism. An associate who wants to buy the practice but cannot finance it is not a succession plan — it is a hope. California healthcare providers have several funding options:

Life insurance-funded buy-out

The incoming associate or the corporation carries a life insurance policy on the departing provider. Upon death, the death benefit funds the buy-out of the deceased's shares at the pre-agreed value. This is the most reliable funding mechanism for death-triggered events, and it avoids the need for the buyer to secure external financing at the worst possible moment.

Benefits: Reliable, immediate funding upon the triggering event. Premiums are predictable. Death benefit is generally income-tax-free to the recipient.

Drawbacks: Premiums increase with age. Coverage may become unavailable or prohibitively expensive if the insured's health declines. Does not cover disability or retirement events.

Disability insurance-funded buy-out

A separate disability buy-out policy triggers a lump sum or installment payment to fund the purchase of a disabled provider's shares.

Benefits: Addresses the disability scenario, which is statistically more likely than death during working years.

Drawbacks: More expensive than life insurance. Benefit periods and definitions of disability vary widely among policies. Requires careful coordination with the buy-sell agreement's triggering event language.

Seller financing

The departing provider accepts installment payments from the incoming provider over an agreed period, secured by the shares themselves.

Benefits: Allows transitions to occur even when the buyer lacks immediate access to financing. Can create favorable tax treatment for the seller through installment sale treatment under IRC Section 453.

Drawbacks: The departing provider bears credit risk. If the practice fails or the buyer cannot pay, the seller may be left with a damaged practice and uncollected receivables. Requires robust security provisions.

Partnership Structures: When There Is More Than One Provider

Many California healthcare practices involve two or more providers who wish to practice together. The professional corporation structure is again required, and the governing documents — the articles of incorporation, bylaws, and shareholder agreement — must address every scenario that might otherwise generate conflict:

•      What happens if one partner wants to leave and the other does not?

•      What if a partner is disabled for six months? A year? Permanently?

•      What if partners disagree on a major business decision?

•      What if one partner's license is suspended pending investigation?

•      Who has the authority to hire, fire, and set compensation?

•      What is the drag-along and tag-along structure if the entire practice is sold?

California professional corporation law is largely silent on these operational questions. Without a shareholder agreement that answers each of them explicitly, the answers will be provided — expensively and unpredictably — by litigation.

Benefits and Drawbacks of Internal Succession

Benefits:

•      Preserves practice culture, patient relationships, and staff continuity

•      Allows gradual transition of patient and referral trust

•      Can generate favorable tax treatment through installment sales

•      Gives the departing provider control over who takes over their life's work

Drawbacks:

•      Requires years of advance planning — this cannot be done quickly

•      Associate-to-partner disputes are among the most contentious in healthcare law

•      Valuation disagreements derail more internal successions than any other single factor

•      Financing uncertainty: many associates lack the capital or creditworthiness to execute a purchase without seller assistance

The Risk of No Plan

If you bring in an associate with a vague understanding that they might “take over someday,” you have not created a succession plan. You have created a relationship whose terms will be disputed the moment circumstances change. Courts, arbitrators, and the Medical Board do not fill in the blanks charitably when healthcare partnerships dissolve without documentation.
