2026 Fee Ranges and Billing Structures for DSO Practice Sale Attorneys
Most DSO transactions use hourly billing. Hourly billing remains the standard legal-fee structure for M&A work, while flat fees tend to appear on smaller, simpler asset sales. For dental-specific transactions, some dental M&A attorneys offer fixed fees for narrow tasks such as reviewing a practice sale agreement.
Hourly rates vary by firm type and market. M&A attorneys at boutique and larger firms bill a range of partner rates. Senior M&A associate billing rates at larger firms often exceed $1,000 per hour. The national average hourly rate for corporate law, which includes M&A work, is $461 according to Clio’s 2025 Legal Trends Report. Partner rates at major U.S. firms for M&A matters often exceed $1,000 per hour in large markets and can reach $2,000 per hour at the top end.
General healthcare M&A counsel, who handle dental alongside veterinary, ophthalmology, and other specialties, may quote lower hourly rates but often need more time to work through dental-specific rules. Healthcare deals add specialized work because of regulations such as HIPAA, Stark, and anti-kickback laws, which can increase attorney fees beyond standard business-sale ranges. A dental-specific attorney who already understands these rules can move faster, which can reduce billable hours.
McLerran’s CPA-built EBITDA narrative, prepared before the deal goes to market, gives counsel a clear, defensible financial package. That preparation can reduce the back-and-forth that drives hourly bills higher.
Phase-by-Phase Cost Breakdown of Legal Work
Attorney fees in a DSO transaction rarely appear as a single lump sum. They usually build across several phases, and each phase has its own scope and cost drivers.
- LOI review and negotiation: The letter of intent (LOI) is the term sheet that sets price, structure, and exclusivity. Most LOI clauses are non-binding on price but binding on confidentiality, exclusivity (no-shop), and deal structure, which can lock sellers out of better offers for 60–120 days if they sign without counsel. LOI review costs can vary based on the attorney and the complexity of the document, but these early fees often carry significant strategic weight.
- Asset purchase agreement (APA) drafting and negotiation: The APA is the main transaction document. Once the LOI is signed, the APA translates the commercial framework into binding legal terms. This phase usually consumes the most attorney hours and often accounts for the largest share of total legal spend.
- Employment agreement review: DSO deals almost always include a multi-year working agreement, commonly 5 years, that governs the seller’s post-close role, compensation, and clinical autonomy. Careful review of these terms can be one of the main factors in long-term satisfaction after closing.
- Equity rollover documentation: When part of the purchase price is paid in DSO equity, which can represent up to 40% of total consideration, the deal requires extra documents. These can include LLC agreement amendments, equity term sheets, and securities-law work. Rollover equity adds a separate stack of documents that can increase attorney hours beyond standard APA drafting.
- Post-sign diligence support: After the LOI is signed, the buyer’s team reviews the seller’s financials, patient records, and operations. Counsel responds to diligence requests, manages third-party consents, and coordinates closing logistics. Extra diligence questions or late-stage changes can extend this phase and raise legal costs.
McLerran’s quality-of-earnings defense, which involves defending the EBITDA it underwrote when the buyer’s team pushes back, can shorten the post-sign diligence phase and reduce the attorney hours required to manage it.
2026 DSO Transaction Attorney Fee Benchmarks
| Transaction Phase | Low Range | Mid Range | High Range | McLerran Mechanism That Reduces Hours |
|---|---|---|---|---|
| LOI Review & Negotiation | Flat fee options | Moderate costs | Higher costs | Competitive bid process creates a stronger LOI baseline, which can reduce negotiation rounds |
| APA Drafting & Negotiation | Lower costs | Moderate costs | Higher costs | CPA-built EBITDA narrative provides a clear financial package that can limit APA redlines |
| Employment Agreement Review | Lower costs | Moderate costs | Higher costs | McLerran negotiates non-punitive earnout and work-back terms at the LOI stage, before counsel engages |
| Equity Rollover Documentation | Lower costs | Moderate costs | Higher costs | Multi-structure financial forecasting clarifies equity terms before legal drafting begins |
| Post-Sign Diligence Support | Lower costs | Moderate costs | Higher costs | Quality-of-earnings defense holds the agreed EBITDA, which can prevent re-trades that extend diligence |
Costs vary by transaction and are not guarantees of cost for any specific deal. Practice owners should consult their legal advisor for a scoped engagement estimate.
Hourly and Flat-Fee Billing in DSO Transactions
Common alternatives to pure hourly billing in M&A transactions include flat fees, capped hourly billing, and, less often, partial success-fee components. For a DSO affiliation, which usually involves multiple document sets, healthcare regulations, and an unpredictable number of negotiation rounds, flat fees can be difficult for attorneys to offer without tight limits on scope.
Most attorneys handle dental practice sales on hourly rates, with total costs driven by the number of negotiation rounds. This structure can make it hard to budget in advance for full DSO sale representation. A capped engagement, where hourly billing applies up to an agreed ceiling, can provide partial predictability. However, overruns are usually billed only on agreed scope changes, so the cap is only as protective as the scope definition.
The practical takeaway is that fewer negotiation rounds usually keep the final bill closer to the low end of any range. A well-prepared seller with a defensible EBITDA analysis and a competitive offer already in hand gives counsel less to dispute. That preparation can be one of the most reliable ways to keep hourly billing more predictable.
How McLerran’s Process Reduces Attorney Hours
McLerran & Associates serves as a dental-specific sell-side advisor, not as legal counsel. The firm focuses on controlling the financial story and creating competitive tension before attorneys engage, which can directly reduce the hours counsel spends defending the deal.
The firm’s process follows four stages that aim to compress legal complexity at each step.
- CPA-led EBITDA analysis up front: Each engagement begins with a diligence-grade valuation built by a CPA and deal advisor. Add-backs, which are discretionary, personal, and non-recurring expenses that affect true profitability, are addressed before the deal goes to market. When the buyer’s quality-of-earnings team reviews the financials, the numbers are more likely to hold, and deals that do not get re-traded usually require fewer additional attorney hours.
- Competitive bid process: McLerran runs a structured, auction-style process over roughly 45–60 days that typically generates multiple offers from a vetted pool of well-backed buyers. A seller who reaches the LOI stage with several competing offers negotiates from a stronger position. The DSO’s counsel has less leverage to push for unfavorable terms, which can shorten negotiation cycles.
- LOI negotiation before counsel engages: McLerran negotiates the key LOI terms, including valuation, cash at close, equity structure, earnout provisions, and employment terms, on the seller’s behalf. By the time the seller’s attorney reviews the LOI, the economic framework is usually more favorable. The attorney’s role then focuses on legal risk review rather than commercial renegotiation.
- Quality-of-earnings defense through closing: After the LOI, McLerran executes the quality-of-earnings defense described earlier and holds the agreed valuation when the buyer’s team scrutinizes the financials. Buyers who attempt to re-trade the deal are reminded that other vetted bidders remain available. This defense can shorten the post-sign diligence phase and reduce the attorney hours required to manage it.
McLerran has closed transactions across its national footprint, including recent closings in Ohio through its Cleveland office led by Justin Klingshim, and in the Southeast through its Atlanta office led by Matt Sutton, using the same process in each market.

Budgeting for DSO Transaction Attorney Fees
A practical starting point for budgeting attorney fees in a DSO transaction is a percentage of total deal value. The specific percentage and dollar amount can depend on factors such as deal size, structure, and the number of entities involved. Legal spend often scales with the size and complexity of the transaction.
Lower-middle-market deals can incur meaningful seller-side attorney fees. For more complex transactions, direct legal costs can be substantial, especially when multiple locations, rollover equity, or earnouts are present.
The factors that push fees toward the higher end of the range can include equity rollover structures, earnout provisions, multi-location complexity, state-level regulatory review requirements, and aggressive buyer’s counsel. That last category, state regulatory requirements, has become more complex in 2026. Several states have introduced new transaction notice and review rules that can extend closing timelines and add legal work. California’s AB 1415, effective 2026, requires certain investor entities to provide at least 90 days’ notice before closing covered healthcare deals, and the state’s office can open a cost-and-market-impact review that extends closing timelines by several months. Washington’s HB 2548, effective June 2026, expanded transaction notice requirements and added a 30-day standstill period. Owners in affected states may want to budget for higher costs and engage dental-specific counsel early.
McLerran’s multi-year, multi-structure financial forecasting models total transaction costs, including legal spend, against projected after-tax proceeds. This approach helps owners evaluate net outcome rather than focusing only on headline price.
Red Flags in Attorney Billing
Not all legal spend supports a better outcome. Several billing patterns can suggest that attorney hours are being used inefficiently or that the wrong counsel has been engaged.
- Open-ended hourly engagements with no scope definition: An attorney who cannot estimate a fee range for a transaction of a given size and complexity has not clearly scoped the work. A scoped engagement letter, even if it presents a range, is a reasonable expectation for most practice owners.
- Excessive rounds of APA negotiation: Each document turn generates billable hours on both sides. More than 3 or 4 substantive turns on a standard APA can suggest that the commercial terms were not resolved at the LOI stage, which pushes business negotiation into the legal phase at attorney rates.
- General healthcare M&A counsel unfamiliar with dental rules: An attorney who must research HIPAA, Stark, anti-kickback, or state dental practice act requirements from scratch will bill those research hours to the client. Dental-specific counsel usually carries that knowledge into the engagement.
- LOI signed before counsel engaged: Signing the LOI before involving a dental attorney is one of the most common and expensive mistakes in a brokered dental practice sale, because the binding provisions discussed earlier can lock you into unfavorable terms for months. Correcting a weak LOI after signing usually requires more attorney hours than reviewing it beforehand.
- Re-trading during diligence: Cash that previously appeared as money at close is increasingly structured as promissory or maintenance notes in the current market, which can shift risk back to sellers. A buyer who attempts to re-trade the agreed price during diligence generates extra negotiation hours. A strong EBITDA defense and competing bidders can be effective deterrents.
When to Engage McLerran Before Hiring Counsel
The sequence of advisor engagement can be as important as the advisors themselves. Engaging McLerran before hiring legal counsel allows the firm to complete the EBITDA analysis, run the competitive bid process, and negotiate the LOI before attorney hours begin to accumulate. By the time counsel reviews the LOI, the economic terms are usually more favorable and the financial package is more defensible.
Engaging counsel first, before a sell-side advisor has established the EBITDA narrative and created competitive tension, often means attorneys are negotiating commercial terms at legal rates without the leverage that competing offers provide. That sequence can be more expensive and may produce weaker outcomes.
McLerran introduces dental-specific attorneys and other transaction specialists as part of its advisory process but stays in its lane. The firm is not legal counsel and does not provide legal advice. Its role is to coordinate the process, defend the valuation, and help the seller reach each legal negotiation from a position of strength.
As of August 2026, current market conditions, including more selective DSO deal activity and buyers who request more contingencies and more complex structures, can make the competitive bid process and quality-of-earnings defense more valuable. More contingencies usually mean more drafting and more negotiation, which can mean more attorney hours. A clean EBITDA narrative and a seller who arrives at the table with competing offers can be key tools for controlling those hours.
McLerran’s national footprint, with offices in Cleveland, Atlanta, Northern Virginia, Los Angeles, and Phoenix, means the firm has closed transactions across regions in the current market and understands how local buyer appetite, state regulatory requirements, and deal structures can vary by geography.
Owners who want to explore their options before committing to a specific path can attend the McLerran M&A Summit on October 29–30, 2026, a dental-only event built for owners who have not decided yet. The event features expert panels, one-on-one CPA sessions, and a complimentary practice valuation, which the firm values at $2,500.

Frequently Asked Questions
How much should I budget for attorney fees when selling my dental practice to a DSO?
A practical starting range for many premier single-location practices is a moderate amount in seller-side attorney fees. The final figure can be driven by deal complexity, the number of negotiation rounds, and whether the transaction involves equity rollover, earnout provisions, or multi-location structures. A useful rule of thumb is a small percentage of total deal value. Practices in states with new 2026 transaction notice and review requirements, including California and Washington, may want to budget for higher costs and engage dental-specific counsel early. One of the most reliable ways to keep legal spend toward the low end is to reach attorney engagement with a defensible EBITDA analysis and a competitive offer already negotiated at the LOI stage.
What is the difference between hourly and flat-fee billing for DSO transaction attorneys, and which is better for a practice owner?
Hourly billing is the standard structure for DSO transactions because the scope of work, including document turns, negotiation rounds, and diligence requests, can be hard to predict in advance. Flat fees are sometimes available for limited-scope work, such as a standalone LOI review, but full transaction representation on a flat-fee basis is uncommon for DSO deals with any real complexity. For a practice owner, the more useful question is how to reduce the total hours billed under either structure. A clear financial package, a competitive offer, and favorable LOI terms negotiated before counsel engages can compress billable hours regardless of billing method. McLerran’s sell-side process is designed to deliver those elements before the attorney’s clock starts running.
Why does engaging McLerran before hiring an attorney reduce my total legal costs?
Attorney hours tend to accumulate when commercial terms are unresolved, financial narratives are weak, or the seller lacks negotiating leverage. McLerran addresses all three before counsel engages. The firm’s CPA-led EBITDA analysis produces a diligence-grade financial package that limits the buyer’s ability to challenge the numbers during the legal phase. The competitive bid process described earlier gives the seller leverage at the LOI stage by ensuring multiple well-backed buyers are competing for the practice. McLerran’s LOI negotiation then resolves valuation, equity structure, earnout terms, and employment provisions at the commercial level, which narrows the attorney’s scope to legal risk review rather than commercial renegotiation. Each of these steps can reduce the hours counsel must bill to close the transaction.
What are the biggest factors that cause DSO practice sale attorney fees to exceed the standard range?
Several factors can push legal costs above a typical benchmark range. Equity rollover structures, where part of the deal is paid in DSO equity rather than cash, require extra documentation such as LLC agreement amendments and securities-law work. Earnout provisions, which tie part of the purchase price to future performance targets, require careful drafting and often generate significant negotiation. Multi-location practices involve more complex representations, warranties, and consent requirements. State-level regulatory review requirements, which have expanded in several states as of 2026, can extend closing timelines and add legal work. Aggressive buyer’s counsel, which is common when well-backed buyers are protecting downside risk in a more cautious market, can generate more document turns and more billable hours on both sides. A seller who reaches the transaction with a strong EBITDA narrative and competing offers has some of the most effective tools for limiting each of these cost drivers.
Should I sign the LOI before engaging a dental-specific attorney?
Practice owners generally should not sign the LOI before engaging a dental-specific attorney. The LOI sets the commercial framework for the entire transaction, including exclusivity provisions that can lock a seller out of competing offers for 60–120 days. While price is often non-binding at the LOI stage, confidentiality, no-shop, and deal structure clauses are usually binding from the moment of signing. Signing the LOI before counsel reviews it is one of the most common and costly mistakes in a dental practice sale, because correcting unfavorable terms after signing usually requires more attorney hours and more leverage than reviewing the document beforehand. McLerran negotiates the material commercial terms of the LOI on the seller’s behalf before counsel engages, so the attorney’s review focuses on legal risk rather than commercial renegotiation. Owners can benefit from engaging both their sell-side advisor and their dental-specific attorney before signing any LOI.
