Yes — dental practice agreements can be renegotiated after signing. Whether a change will hold depends on what your agreement requires procedurally, whether the other party consents, and how the amendment is documented. In California, where professional corporations carry specific ownership and governance requirements, informal understandings between practice owners often create more problems than they resolve. Getting the process right matters as much as reaching the agreement.
What Types of Agreements Can Be Renegotiated?
Most dental practice agreements can be modified if the parties agree and follow the procedures required by the contract. Partnership agreements, shareholder agreements, associate contracts, and management services agreements all fall into this category.
The starting point is always the amendment clause. Some agreements allow changes through a written amendment signed by both parties. Others require unanimous owner approval, a supermajority vote, or board action before a change becomes effective. An amendment that skips a required step may not be enforceable, even if both parties intended it to be.
This matters practically. A two-dentist practice in which one partner has informally agreed to a revised compensation split, but the shareholder agreement requires a written amendment executed by both shareholders, remains governed by the original terms if no signed amendment exists. Oral agreements between practice owners are difficult to enforce and easy to dispute.
Why Do Dentists Renegotiate Practice Agreements?
Renegotiation is rarely about conflict at the outset. More often than not, the practice has changed, and the agreement has not kept pace. Common triggers include:
- A shift in ownership responsibilities when one partner transitions to a clinical-only role
- Production disparities that make the original compensation formula feel inequitable
- The addition of a new associate or partner that the original agreement did not contemplate
- Early succession planning when one owner is approaching retirement
A specific scenario worth illustrating: two partners initially split revenue equally and divide administrative responsibilities the same way. Over time, one partner handles all vendor relationships, payroll oversight, and insurance credentialing while the other focuses exclusively on patient care. If the original agreement does not distinguish between clinical and administrative contributions, that omission can lead to friction when compensation expectations diverge.
Addressing these gaps early, before either party feels aggrieved, produces better outcomes than waiting until the relationship is already strained.
What Happens When One Party Refuses?
If one owner refuses to approve proposed changes, your options depend on what the agreement says about disputes and deadlock. Some shareholder agreements include buyout triggers or mediation requirements for exactly this situation. Others are silent, leaving the parties to negotiate or litigate.
California courts will generally enforce the amendment procedures parties agreed to at the outset. If your agreement required unanimous written consent and you proceeded without it, a court is unlikely to recognize the informal modification, regardless of what was discussed or assumed.
Before attempting renegotiation, review what the contract requires. Then review what happens if a consensus cannot be reached. Both questions shape the strategy.
What Should You Review Before Proposing Changes?
Three areas deserve attention before any renegotiation begins.
- Amendment requirements. What does the agreement require procedurally? Who must approve, and in what form?
- Downstream effects. Changes to ownership percentages, compensation, or management authority can affect practice valuation, financing covenants, and tax structure. A revised compensation arrangement that shifts income allocation between owners may have pass-through tax implications that neither party anticipated. Review proposed changes with both legal and financial counsel before finalizing terms.
- The gap between paper and practice. In many California dental practices, the written agreement and the actual operating arrangement have drifted apart over time. Before renegotiating specific terms, it is worth auditing whether the existing agreement still accurately reflects how the practice operates — because lenders, buyers, and future partners will rely on the written document rather than the informal arrangement.
Review Your Agreement Before a Conversation Becomes a Conflict
The best time to revisit a practice agreement is before a specific dispute has defined the terms of the conversation. If your Los Angeles dental practice is considering changes to a partnership, shareholder, or management agreement, contact Polished Legal to discuss your options.
FAQs
Does every amendment need to be in writing? Most practice agreements require written amendments signed by the relevant parties. Even where the contract does not expressly require it, written documentation protects all parties by creating a clear record of what changed and when.
Can ownership percentages be changed after the fact? Yes, but the procedure matters. In a California Professional Corporation, changes in ownership may also affect the Dental Board of California’s requirements for shareholder eligibility and reporting. Legal review before finalizing any ownership restructuring is important.
What happens if owners have been operating outside the written agreement? The written agreement generally controls, particularly if a dispute arises. Courts look to the contract, not the informal practice. Documenting the actual arrangement through a formal amendment reduces the risk that a party later takes a position based on the original written terms.
Should a lawyer review proposed amendments? Yes — and ideally before negotiations begin, not after. Understanding what the amendment requires procedurally, and what the downstream effects may be, shapes how you approach the conversation with the other party.
