Partner Buyouts & Shareholder Disputes

When the Partnership Ends, Get the Number Right.

My valuation methodology has been challenged through full Florida appellate review and affirmed both times — and as a Licensed Florida Business Broker who has closed more than 80 company transactions, I bring real-world deal evidence to the buyout table, not just classroom theory.

Most partner-buyout valuations turn on three things: which standard of value the buy-sell or the statute requires, whether the discount and premium adjustments are supportable, and whether the conclusion will survive a deposition by the opposing expert. I prepare the report knowing all three will be tested — because in litigated buyouts, they almost always are.

Why This Matters in a Buyout

Methodology That Has Been Tested. Market Data That Has Been Lived.

Partner buyouts get litigated more often than people expect. The valuation has to survive scrutiny on two fronts at once — analytical rigor and real-world market evidence. I bring both.

2 of 2valuations affirmed on appeal

Methodology Affirmed by the Appellate Courts.

When my valuations have been challenged through full Florida appellate review, both have been affirmed. Appellate review is the most contentious environment a business valuation can face — the opposing expert has had time to dissect the report, the briefs are on the record, and the court is deciding whether the methodology was sound, not just whether the conclusion was reasonable.

The same analytical framework that survived appellate review in those engagements gets applied to my partner-buyout work: standard-of-value discipline, supportable normalization, defensible discounts and premiums, and a report exhibit chain that a trier of fact can follow factor by factor.

80+company transactions closed

Real Deal Evidence, Not Just Comparable Databases.

I am a Licensed Florida Business Broker with more than 80 closed company transactions on my record. That experience matters in a buyout because it tells me what businesses actually clear at — at the negotiating table, with a real buyer and a real seller, after due diligence and after price retrades.

Most appraisers know what the comparable databases say a business is worth. Far fewer have been on the deal floor when the buyer found a problem in the inventory count, the seller wanted to hold back receivables, and the closing got rescheduled three times. That deal-floor experience is what makes my discount-for-marketability and minority-interest opinions hard to attack on cross-examination.

Four Buyout Contexts

The Buyout You Are In Determines Almost Everything.

Partner buyouts are not one engagement type — they are four. The standard of value, the discount framework, the controlling agreement, and the litigation posture all shift depending on which buyout you are actually inside. I value each on its own terms.

Context 1

Departing-Shareholder Buyouts

An S-corp or C-corp shareholder is being bought out under a buy-sell agreement, a shareholders' agreement, or a stock purchase agreement. The agreement itself may dictate the standard of value, the valuation date, the appraiser-selection mechanism, and the discount framework. The first task is reading the agreement carefully — not running the valuation. A surprising number of buy-sells point to a value mechanism that nobody has actually applied for years, and the parties find out only at the buyout. I value to the agreement when the agreement is clear, and to the controlling statute when it is not.

Context 2

LLC Member Buyouts

LLC member buyouts run on different statutory rails than corporate buyouts. Florida's Revised Limited Liability Company Act (Chapter 605, F.S.) governs dissociation, distributional interests, and the rights of withdrawing members, and the operating agreement may modify many of those defaults. The standard of value can shift between fair value and fair market value depending on whether the buyout is consensual, statutorily triggered, or judicially ordered. The classification decision drives the entire engagement — including whether marketability and minority discounts even apply.

Context 3

Litigated Buyouts — Oppression & Dissociation

Where a minority shareholder or LLC member alleges oppression, freeze-out, breach of fiduciary duty, or grounds for judicial dissolution, the buyout often becomes a court-ordered remedy — typically at fair value as of the filing or trigger date, frequently with no marketability or minority discount. The valuation has to be built to survive deposition by the opposing expert and to anchor a settlement in the meantime. I have served as the appraiser in oppression-adjacent partner disputes from convenience stores in Collier County to lighting-industry pre-arbitration in California.

Context 4

Negotiated & Amicable Buyouts

The cleanest engagements are the ones where the partners want to do the right thing and just need an independent number they both trust. In those cases I can be retained as the joint neutral appraiser — one engagement letter signed by both sides, one report delivered simultaneously, no party-favorable advocacy in the language. The neutrality designation typically lowers cost meaningfully, shortens the timeline, and removes the temptation for either side to shop the report. Ask whether your case is a fit.

The Pivotal Issue

Fair Market Value vs. Fair Value.

The single most consequential decision in a partner-buyout valuation is the standard of value. The two terms sound nearly identical. They are not. The choice can swing the conclusion by 20 to 40 percent — and the buy-sell, the statute, or the court determines which one applies.

Fair Market Value

Fair Market Value (FMV)

The price at which the interest would change hands between a hypothetical willing buyer and a hypothetical willing seller, neither under compulsion, both with reasonable knowledge of the relevant facts. This is the standard typical of buy-sell agreements, gift and estate engagements, and many negotiated buyouts.

  • Marketability discount typically applies
  • Minority-interest discount typically applies
  • Hypothetical willing-buyer / willing-seller frame
  • Standard for IRS, gift, and estate work
  • Often the buy-sell default unless modified
  • Lower conclusion in most fact patterns
Fair Value

Fair Value (FV)

A statutory standard most often applied in dissenting-shareholder rights, oppression cases, and judicial buyouts. Florida treats the dissociated member's distributional interest under Chapter 605 with its own valuation framework. Fair value frequently disallows marketability and minority discounts on policy grounds — the departing party should not be penalized for the very illiquidity created by the dispute.

  • Marketability discount often disallowed
  • Minority-interest discount often disallowed
  • Court or statute determines specifics
  • Standard for oppression and dissociation
  • Pro-rata share of enterprise value frame
  • Higher conclusion in most fact patterns
Reading the Trigger Document Comes First.

Before I open the financials, I read the buy-sell, the operating agreement, the shareholders' agreement, and any pleadings on the record. The trigger document — or the statute it points to — usually decides which standard of value applies, which valuation date controls, whether discounts are in play, and what role the appraiser is being asked to fill. Skipping that step is the most common reason a buyout valuation gets attacked at deposition. I do not skip it.
One number. Both partners.
Joint Neutral Engagements

When Both Partners Want One Appraiser.

Litigation is expensive, and most partner buyouts do not need two competing experts duking it out. When both partners (or both counsel) agree, I can be retained as the single neutral appraiser serving both sides — one engagement letter, one report delivered simultaneously to both, no party-favorable advocacy in the language.

This is not theoretical. In the past several years I have served as the neutral appraiser in partner-dispute mediations across Florida — including a real estate rentals partnership in Tampa (2020), a real estate storage company partnership (2019), and a meat wholesaler partnership (2011). Each closed at mediation without going to trial.

The neutrality designation is meaningful because it changes the rules: my deliverable is the same report to both parties at the same time, no party-favorable framing, and no risk that the opposing expert will mischaracterize the methodology — there is no opposing expert. For attorneys representing both sides of an amicable buyout, it can dramatically reduce cost and shorten the timeline. Ask if it fits your case.

Common Questions

What Buyout Counsel and Their Clients Ask First

Which standard of value applies in a Florida partner buyout — fair market value or fair value?
It depends on the trigger. If the buyout is governed by a buy-sell agreement, an LLC operating agreement, or a shareholders' agreement, that document usually controls — and most private agreements default to fair market value, often with explicit marketability and minority discounts. If the buyout is governed by Florida statute — for example, a dissociated LLC member valued under Chapter 605, F.S., or a dissenting shareholder under Chapter 607, F.S. — the standard is typically fair value, frequently without marketability or minority discounts on policy grounds. The first thing I do on any buyout engagement is read the controlling document and confirm the standard of value with counsel before opening the financials.
Our buy-sell has its own valuation procedure. Can you still help?
Yes — most engagements I take begin exactly that way. Buy-sell valuation procedures range from formula-based (a multiple of EBITDA, a book-value formula, a five-year average of distributions) to appraiser-driven (single appraiser, dual appraiser with a baseball-arbitration tiebreaker, or three-appraiser panels). My role can be to apply the formula and validate the result, to serve as one of the two appraisers, to act as the neutral tiebreaker, or to challenge or defend a procedure that produces an unreasonable outcome. I read the procedure first and tell counsel whether what the agreement actually says is what the parties think it says — they are often different.
Do marketability and minority-interest discounts apply in our case?
That is one of the most consequential questions in any buyout valuation, and the answer depends on the standard of value. Under fair market value, both discounts typically apply and can move the conclusion by 25 to 45 percent in combination. Under fair value — most often in oppression cases and statutory dissociation — both discounts are frequently disallowed on the policy grounds that a departing partner should not be penalized for the illiquidity created by the dispute itself. I quantify the discounts using empirical studies (restricted-stock and pre-IPO data for marketability, and data-driven minority-interest analysis for control premiums), document the inputs in a dedicated report exhibit, and stand behind the conclusions on cross-examination.
Can you serve as a joint neutral appraiser for both partners?
Yes. When both partners or both counsel agree, I can be retained as the single neutral appraiser serving both sides — one engagement letter signed by both parties, one report delivered simultaneously, no party-favorable advocacy in the language. Recent examples include partner-dispute mediations involving real estate rentals, real estate storage, and a meat wholesaler — all in Tampa-area Florida. The neutrality designation typically lowers cost meaningfully and shortens the timeline. Ask whether your case is a fit.
What about minority oppression and judicial dissolution cases?
Florida courts frequently impose a fair-value buyout as an equitable alternative to dissolution where minority oppression, freeze-out, or breach of fiduciary duty is established. The valuation in those engagements has to be built to survive deposition and trial — not just to anchor a settlement. The standard is typically fair value as of the filing date or the date of the precipitating act, often without marketability or minority discounts, and the appraiser frequently must address whether non-economic conduct by the controlling owners (excessive compensation, related-party leases, discretionary diversions) requires normalization adjustments. I have valued in oppression-adjacent partner disputes across multiple Florida judicial circuits.
Do you handle LLC member buyouts differently than corporate stock buyouts?
Yes. The statutory framework is genuinely different. Florida LLC member buyouts run under Chapter 605 of the Florida Statutes, which governs dissociation, distributional interests, and the rights of withdrawing members — and the LLC operating agreement can modify many of those defaults in ways that a corporate shareholders' agreement cannot. Corporate stock buyouts run under Chapter 607, the bylaws, and the shareholders' agreement. The valuation date convention, the standard of value default, and the discount framework all differ. I read the controlling instrument and the relevant chapter before pricing the engagement.
Will the report hold up at deposition and trial?
That is the standard the report is built to. My CV documents 11 court testimony appearances, 11 deposition appearances, and 3 mediations. My valuation methodology has been challenged through full Florida appellate review in family-law engagements and was affirmed both times. The CBA designation is the only U.S. business-appraisal credential that requires peer review of completed reports as a condition of certification, which is one reason the methodology survives cross-examination. The same framework that survived appellate review in those cases is what I bring to partner-buyout work.
What documents do you need to start a partner-buyout valuation?
For most engagements: the buy-sell, operating agreement, or shareholders' agreement (and any amendments); three to five years of business tax returns; the most recent year-to-date P&L and balance sheet; owner compensation history for all owners; a fixed-asset schedule; the lease; any pleadings filed to date if the matter is in litigation; and a 60- to 90-minute management interview by Zoom. Where the buyout is statutory (dissociation or oppression), I will also want the dissociation notice, the demand letter, or the relevant pleadings. I send a tailored information request once I have talked through the triggering facts with counsel and we have fixed the valuation date and the standard of value.
Do you offer a Phase I diagnostic before committing to a full report?
Yes. For many buyout engagements, a Phase I preliminary calculation of value gets the parties to a defensible number range in two to three weeks, at a fraction of the cost of a full Conclusion of Value report. Phase I is enough for many mediation and settlement contexts — particularly when the goal is to find out whether the buy-sell formula is reasonable or whether a settlement is even on the table. Phase II — the full Conclusion of Value with all three approaches developed — is the right deliverable when the case is heading to trial, when one side is likely to challenge the methodology, or when a court-ordered fair-value determination is required.
Can you take buyout engagements outside of Florida?
Yes. While the bulk of my work is Florida, my CV documents engagements in California (entertainment-industry pre-arbitration), Delaware, Texas, Arizona, and Quebec, Canada. The CBA credential and NACVA standards are recognized nationally, and I work with local counsel to confirm any state-specific buyout statutes — corporate-code dissenting-shareholder regimes and LLC dissociation regimes vary meaningfully by state — before issuing the report.

"Every report has my name and my signature. I do the work, I take the deposition, I sit in the chair."

In a partner buyout, the appraisal is often the foundation of the deal itself. As a Licensed Florida Business Broker, I have personally facilitated the sale of more than 80 companies — real closings, real terms, real buyers and sellers. That transaction experience is what separates an appraiser who reads market data from one who has actually closed it. I will personally complete your engagement and stand behind every conclusion. No junior staffer, no rotating team.

The CBA designation I hold is the only U.S. business-appraisal credential that requires peer review of completed reports as a condition of certification — fewer than 400 appraisers nationwide hold it. Two of my reports have been challenged through full appellate review by the Florida appellate courts. Both were affirmed.
