For counsel and owners
Condemnation cases are decided by experts, not by argument
Liability is rarely in dispute. What is in dispute is a set of technical questions about value, engineering, access and use, and those are answered by witnesses. Choosing them, instructing them and preparing them is most of the work.
The disciplines
Who gives evidence in a condemnation case
Appraisal
The central witness. Produces the valuation and carries the compensation figure.
Engineering
Grade, drainage, construction impacts and whether a proposed cure is physically possible.
Land planning
Zoning, entitlement probability and what the remainder can still be developed for.
Traffic and access
Movements, sight lines, turning paths and whether remaining access serves the use.
Business damages and economics
Where a state compensates business loss, and for income analysis generally.
Environmental
Contamination, wetlands and remediation cost, which can dominate a valuation.
The premise
An appraiser cannot carry the whole case alone
The valuation is the conclusion, and the valuation rests on facts the appraiser is not qualified to establish. Whether the remainder can still be developed is a planning question. Whether the new grade can be reached by a loaded vehicle is an engineering question. Whether the surviving access works for the use is a traffic question.
An appraiser who opines on all of it is exposed on cross examination, and in some cases excluded. An appraiser whose assumptions are supported by the people qualified to make them is much harder to move.
The practical consequence is a sequencing decision. Supporting experts have to be retained early enough that the appraiser can rely on their conclusions, rather than late enough that they are explaining an appraisal already written.
The lifecycle
Working with an expert, start to finish
Retain
Timing, conflicts, budget and the decision between consulting and testifying roles.
Instruct
A scope that names the question, the assumptions and the materials. Vagueness here is expensive later.
Report
What it must contain, what it should not, and the discoverability of what surrounds it.
Test
Deposition, admissibility challenge, direct and cross. Where opinions are either confirmed or broken.
Beyond testimony
What experts do that never reaches a courtroom
Case assessment
An early read on whether the agency valuation is vulnerable and where.
Document review
Working through plans, appraisals and agency files for what the record actually shows.
Settlement support
Most cases settle. Expert work shapes what they settle at.
Trial exhibits
Plans, overlays and comparisons that make a technical point legible to a jury.
Common questions
Questions counsel and owners ask
How many experts does a condemnation case need
Often one. A straightforward partial taking may need only an appraiser. The question is whether the appraisal rests on assumptions outside the appraiser\u2019s expertise, and if it does, whoever can support those assumptions should be retained.
Is a consulting expert discoverable
Generally not, which is why early work is often done in a consulting capacity before anyone is designated to testify. Rules vary and the distinction should be set at retention rather than assumed later.
When is it too late to retain an expert
Once disclosure deadlines have passed, usually. The more useful answer is that it becomes too late to be fully effective much earlier, because the best expert work shapes the record rather than commenting on it.
Can the same appraiser who valued the property for negotiation testify
Usually yes, and continuity helps. What matters is that the opinion was formed independently and that the file supports it, since everything will be produced.
Does the owner pay for all of this
In most states each side bears its own costs, so expert fees come out of the recovery. Some states shift fees where the award exceeds the offer by a margin, which changes the calculation substantially.
Who decides which experts to use
Counsel, with the appraiser\u2019s input. The appraiser usually knows soonest which assumptions in the valuation need outside support.
Start with the valuation, then work out what it rests on
The appraisal is the spine of a condemnation case. Everything else exists to support or dismantle an assumption inside it.
