Succession planning gets treated as a synonym for "eventually selling the practice." For a solo owner, that's close enough. For a multi-partner practice, it's not, since succession isn't one transaction, it's a set of triggers, any of which can happen in any order: retirement, disability, death, or a partner simply deciding to leave. A plan that only addresses the scenario you're picturing right now, usually your own eventual retirement, leaves the practice exposed to every other scenario.

This guide covers what dental practice succession planning actually requires when there's more than one owner at the table. The same principles apply to medical practice succession planning for multi-physician groups, though state-specific licensing rules can vary by profession.

Why Multi-Partner Succession Is More Complex

A single-owner transition has one buyer and one seller. A multi-partner practice has to answer a harder set of questions before any transition happens: Who has the right to buy a departing partner's share first? How is that share valued, and does the formula stay consistent no matter which partner triggers it or when? What happens if two partners want to buy the same departing share? Without answers written down in advance, these questions get resolved during the most stressful version of the conversation, not the calmest one. A dental transition lawyer who works with multi-partner practices regularly has usually seen every version of this conversation go wrong at least once, which is exactly the experience worth borrowing before it's your practice working it out in real time.

The Buy-Sell Agreement: Your Succession Plan's Foundation

A buy-sell agreement is the document that actually operationalizes succession. It should be negotiated while every partner is healthy, present, and has no idea who will trigger it first, since that's the only point at which everyone's interests are genuinely aligned.

‍

The agreement should also specify who calculates value (a named independent appraiser is generally cleaner than "the partners will agree"), and confirm that the valuation formula is the same regardless of which partner triggers the buyout or when. A formula that happens to favor whoever is negotiating it in the moment is a formula that will be renegotiated in a dispute later.

Funding the Buyout

Even a fair valuation is meaningless if the remaining partners can't actually pay it. Most multi-partner practices use one or a combination of:

Life insurance is worth planning early specifically because death is the one trigger with no notice period. A practice that hasn't funded that scenario in advance is relying on remaining partners having personal liquidity on short notice, which is rarely a safe assumption.

Identifying and Preparing a Successor

• Internal associate. Often the smoothest path, since the successor already knows the patients, staff, and how the practice runs. Requires starting the associate-to-partner conversation years, not months, before a transition.

• Existing co-owner. In a multi-partner practice, remaining partners may simply absorb a departing partner's share rather than bringing in someone new.

• External buyer. Necessary when no internal candidate exists, but requires more due diligence and a longer transition period for patient and staff continuity.

• Family member. Possible in some structures, though most states require the practice to remain owned by licensed professionals, which can limit direct inheritance regardless of family intent.

Whichever path applies, the earlier a successor is identified and brought into the planning conversation, the more the transition can be gradual rather than abrupt. This is also where dental practice transition planning connects back to the buy-sell agreement itself, since the funding mechanism and valuation formula need to work whether the eventual buyer is an existing partner, an associate, or someone entirely new to the practice.

Succession Planning Timeline: Start Earlier Than You Think

Most dental practice transition planning should begin three to five years before an anticipated exit, not at the point of decision. That gives enough time to identify a successor, mentor them into the role, get the buy-sell agreement and funding mechanism in place, and address any valuation gaps well before anyone is under pressure to act quickly. Heading into 2027, practices that begin this conversation now are working from choice rather than urgency.

Common Multi-Partner Succession Mistakes

• No written buy-sell agreement, or one that hasn't been reviewed in 5+ years
• A valuation formula that was never actually tested against a real appraisal
• No funding mechanism in place for the death or disability trigger specifically
• Assuming a family member can inherit ownership without confirming state licensing rules
• Waiting until a partner announces they're leaving to start the conversation
• Treating succession planning as separate from estate planning, when the two overlap significantly

That last point matters more than it looks. A buy-sell agreement funded by life insurance sits at the intersection of business succession and personal estate planning, and we cover the estate planning side in more detail in estate planning essentials for dentists.

The Bottom Line

Multi-partner succession planning isn't a single document, it's a coordinated set of agreements, funding mechanisms, and timelines that all have to work together regardless of which partner triggers them first or when. The practices that handle this well start the conversation years before anyone is actually leaving, while every partner still has equal reason to make the terms fair.

If your practice doesn't have a current buy-sell agreement, or hasn't reviewed one in several years, contact Dental & Medical Counsel to talk with a dental practice transition attorney about getting one in place. Whether you already work with a dental lawyer on other matters or are looking for a dental transition attorney for the first time, the agreement is worth reviewing well before any partner is actually planning to leave.

Frequently Asked Questions

How often should a multi-partner buy-sell agreement be reviewed?

Every two to three years, or any time a partner joins, leaves, or the practice's value changes significantly. A valuation formula that made sense five years ago may no longer reflect the practice's actual worth or ownership structure.

Do all partners need to agree on the valuation method in advance?

Yes, and this is exactly why it should be negotiated before anyone is actually leaving. Once one partner announces a departure, the incentive to negotiate a fair, neutral formula disappears for at least one side of the table.

What happens if a multi-partner practice has no buy-sell agreement when a partner dies?

The deceased partner's ownership interest typically passes to their estate, which can leave the remaining partners in business with an heir who has no dental license and no interest in running a practice. This is one of the most disruptive outcomes succession planning is meant to prevent.

Can a dental practice succession plan include a family member as a future owner?

Sometimes, but most states require practice ownership to stay with licensed dental professionals. If a family member isn't a licensed dentist, direct ownership transfer usually isn't an option regardless of the succession plan's other terms.

Is succession planning only relevant for partners nearing retirement?

No. Disability and death don't wait for a convenient time, which is exactly why the agreement needs to be in place well before retirement is on anyone's mind, not drafted reactively once it is.
