How Franchise Expert Witnesses Get Excluded Under Daubert — and How to Survive the Cross

Daubert is not a medicine problem. Under Kumho Tire and the 2023 amendment to Federal Rule of Evidence 702, the trial court's gatekeeping applies to every form of specialized testimony — franchise included. A 20-year study of 2,842 challenges to non-medical experts found that roughly half of those opinions were excluded or partially excluded, and the single most-cited reason was “unreliable methodology.”

The exclusion rarely happens in a written motion alone. It is built, piece by piece, in the deposition cross-examination — where opposing counsel walks a franchise expert into conceding scope, methodology, or an assumption that unravels the whole opinion. Here are the three traps, and how a prepared expert answers each one.

The three ways franchise experts lose ground

Scope: testifying outside your lane

The cross-examiner's question sounds simple:

You opine the franchisor breached the standard — but you've never operated in this brand's industry, have you?

Why it works: Anchor to the FTC Franchise Rule and the FDD.

A stronger answer: “I apply the FTC Franchise Rule and accepted franchising standards, which govern the relationship and disclosures, to the documented FDD and conduct; I cited the standards.”

Methodology: the reliability attack

The cross-examiner's question sounds simple:

Your opinion relied on the FDD and the file — you didn't speak to the franchisor, did you?

Why it works: Methodology / record basis.

A stronger answer: “I analyzed the documented disclosures and conduct against the standards, the proper basis, and noted that limit.”

Assumptions: the one premise that sinks the opinion

The cross-examiner's question sounds simple:

You assume the franchisee followed the system — but franchise outcomes depend on the operator too, don't they?

Why it works: The operator-conduct assumption. Address both sides.

A stronger answer: “I addressed both the franchisor's obligations and the documented operator conduct and apportioned my analysis accordingly.”

How to prepare for the cross before you're sworn in

Every one of those traps is defeatable — but not by reading your report one more time. The experts who survive the cross have done three things:

• Rehearsed the cross-examination out loud, repeatedly, against a realistic examiner — so the scope concession, the methodology defense, and the assumption hedge are second nature.
• Mastered the record, so that when counsel asks them to recall the one line buried in thousands of pages of the FDD, agreements, and operations records, they can produce it in seconds rather than fumble.
• Stress-tested the report against FRE 702 — finding the reliability gaps before opposing counsel does.
