The Real Estate Expert as an Expert Witness in International Arbitrations

1. The Role of the Expert Witness in Real Estate Litigation

In international real estate arbitration, theexpert witnessplays a crucial role. Unlike a fact witness (who testifies about what he saw or heard), the expert witness providesspecialized technical opinionsbased on their experience and professional knowledge.

1.1. Difference between Party Expert and Court Expert

There are two main types of expert in international arbitration:

• Party-Appointed Expert:Appointed and paid for by one of the parties. Their duty is to help the court understand complex technical issues, while maintaining independence and objectivity.
• Tribunal-Appointed Expert:Appointed by the arbitral tribunal to provide a neutral opinion on specific technical issues.

In practice, most international real estate arbitrations use party experts, who must maintainintellectual independenceeven if they are hired by one of the parties.

1.2. The Primary Duty of the Expert

According to theIBA Rules on the Taking of Evidence in International Arbitration(Art. 5), the primary duty of the expert isattend the arbitration tribunalregarding their specialization. This means:

• Maintain independence and impartiality
• Not acting as attorney for the party hiring you
• Present all technical conclusions, including those unfavorable to the hiring party
• Accept corrections when technical evidence justifies it

2. Main Arbitration Forums: ICC, LCIA, UNCITRAL

3.2. The Language of the Report

In international arbitration, the report must be written in theprocedure language(typically English). But there are important nuances:

• Legal English:Use of accurate legal terminology (not just technical English)
• Clarity for non-experts:Arbitrators may not be real estate experts
• Sworn translation:If the original report is in Spanish, it must be translated with a sworn translator

Undeclared assumptions can be used by the opposing party toinvalidate the conclusionsof the expert.

4. Cross-Examination: Defending the Report in Court

Cross-examination is the most critical moment for the expert. It is where the opposing party will trydestroy credibilityof the expert or at leastweaken your conclusions.

4.1. Cross-Examination Techniques

Lawyers specialized in international arbitration use various techniques:

• Tricky questions:Questions designed to force the expert to contradict himself
• Attack on methodology:Question the methods used by the expert
• Attack on assumptions:Demonstrate that assumptions are incorrect or unrealistic
• Comparison with other experts:Contrast the conclusions with those of the opposing party's expert
• Attack on independence:Try to show that the expert is biased
• Hypothetical questions:“If assumption X were incorrect, would your conclusion change?”

At Prop Trust Verified, we prepare our experts with intensive training sessions.mock cross-examination(mock cross-examination). We teach the golden rules:

1. Listen completely to the question:Do not interrupt, do not anticipate
2. Pause before answering:3-5 seconds to think
3. Answer only what was asked:Do not ramble, do not justify, do not explain more than necessary
4. Don't be afraid to say “I don't know”:It is better to admit ignorance than to speculate
5. Keep calm:Cross-examination is a psychological exercise as well as a technical one
6. Ask to see the document:Never respond to a document without having read it completely
7. Distinguish between facts and opinions:The facts are incontrovertible; opinions are defensible with methodology

4.3. Hot-Tubbing (Joint Conference of Experts)

In some arbitrations, the court may order ajoint conference of experts(hot-tubbing), where both experts testify simultaneously and discuss their differences before the court.

Characteristics:

• Both experts in the room simultaneously
• Direct technical discussion between experts
• The court can ask questions of both
• Objective: identify points of agreement and disagreement

Hot-tubbing requires that the expert be able todefend your positions in real time, without prior preparation.
