What an Appraisal Expert Looks for in a Technical Review for Litigation

Time to Read: 5 Minutes
Technical Level: Moderate

Attorneys often focus on the number at the bottom of an appraisal: the opinion of value. But that number alone doesn’t establish whether the work is credible, supportable, or logically developed. Credibility of a value conclusion must be earned through method, not just stated as fact.

As appraisal experts, we review reports not always because the client is disputing the number itself, but to assess how that number was developed and communicated. A well-executed technical review can reveal whether the analysis aligns with professional standards and whether the report tells a story that holds up under legal scrutiny.

Why Technical Review Can Matter More Than Value

USPAP requires appraisers to develop and report opinions in a way that is independent, impartial, and objective, and supported by relevant evidence and logic. But from the outside, compliance isn’t always obvious, especially in a report crafted to look clean and conclusive.

A technical review helps answer critical questions:

• Was the appraisal developed using recognized methods and applied properly?
• Were those methods clearly supported with accurate data and clear reasoning?
• Does the report communicate conclusions in a way that is internally consistent and sufficient for its intended use?

These questions matter to attorneys, judges, juries, and opposing experts alike, all of whom may rely on the report, or the expert’s testimony about it, as part of the litigation record.

What a Technical Review Evaluates

A technical appraisal review evaluates both development and reporting. The development happens in the appraiser’s mind. The report is how that thinking is conveyed. Credibility in litigation depends on both, and the review examines compliance with appraisal theory and standards.

A technical review typically covers four interrelated areas:

1. Problem Identification and Scope

Review begins with the foundation. Did the appraiser correctly define the appraisal problem, including:

• Intended use and intended user
• Type and definition of value
• Effective date
• Assignment conditions
• Relevant property characteristics

Flaws in this phase often go unnoticed. A report may appear objective and methodical, yet lack true impartiality if the appraisal problem was framed in a way that supports one party’s position. That framing can stem from ethical bias, or simply a competency gap. Either way, it compromises the neutrality of the analysis and introduces risk.

Even when the methods and data appear sound, a technical review can reveal whether objectivity broke down at the outset, before the first calculation was made. If the problem being solved differs from the one another appraiser addressed, or from the question the court actually needs answered, then the conclusions may diverge significantly. In some cases, the opinion may be well-supported but simply not relevant to the legal issue at hand.

2. Application of Appraisal Theory and Methods

Here, the review asks whether the appraiser:

• Applied the core principles of appraisal theory (e.g., supply and demand, substitution, highest and best use)
• Used methods consistent with accepted practice
• Applied those methods logically and consistently

This step is not about analyzing professional discretion and it’s about evaluating whether judgment was exercised within a structured and supportable framework.

3. Data Use and Analysis

The review also assesses how the report handles data:

• Was relevant market data selected and used appropriately?
• Were key facts, assumptions, and adjustments disclosed and explained?
• Were any critical elements omitted, inconsistently applied, or selectively presented?

This is not about second-guessing comparable selection or “finding better comps.” That would require geographic competency. Instead, a technical review checks whether the data supports the conclusions in a clear, internally consistent way, or leaves gaps that affects credibility.

4. Reporting and Communication

Finally, the review examines whether the report communicates:

• The reasoning behind each conclusion, not just the final value
• Enough detail for the intended use, sufficient for parties to follow the logic
• A consistent, accurate, and transparent explanation

Credibility isn’t lost because the work was flawed. It’s lost when people that need to rely on the appraisers work can’t see or understand how the conclusion was reached.

How Technical Review Supports Litigation Strategy

Technical reviews play a role both before and during litigation. In many cases, review is used to evaluate the opposing party’s report, assessing whether the analysis is adequately supported, clearly communicated, and compliant with professional standards. In other cases a technical review is proactive: helping attorneys prepare their own expert, assess a draft report, or avoid surprises before a report is introduced.

In a proactive approach, a technical review doesn’t have to replace the appraiser or offer a competing value. Instead, it supports the process by:

• Preparing experts to defend their conclusions clearly
• Reviewing drafts to strengthen clarity and compliance
• Helping attorneys translate appraisal concepts into legal questions
• Assisting courts and other users in understanding whether the work aligns with professional standards

The Bottom Line

A value conclusion only carries weight when the process behind it is credible, and when the communication of that process is clear, consistent, and supportable. Appraisal review helps determine whether a report meets that standard.

As technical appraisal review experts, we don’t assume the number is wrong. We ask whether it was developed properly, communicated clearly, and stands on a foundation worthy of belief. In litigation, that can matter more than the number itself.
