Expert Witness Testimony

Credible, Objective Certified Arborist Testimony for Legal Disputes in Texas

Expert Witness Services

Tree-related legal disputes are more common than many people realize—and they’re rarely simple. Whether it’s a property boundary disagreement, storm damage, personal injury, or code compliance issue, expert testimony can make or break a case.

At Texas Tree Surgeons, our ISA-Certified and Registered Consulting Arborists (RCA) provide expert witness services for attorneys, insurance providers, municipalities, and property owners across North Texas. With deep expertise in arboriculture, tree risk assessment, and environmental compliance, we deliver clear, defensible insights in court and beyond.

What Is an Arborist Expert Witness?

An arborist expert witness is a credentialed professional who offers independent, fact-based analysis and testimony in legal matters involving trees and landscapes. Their role is to clarify technical, scientific issues for judges, juries, and mediators—helping legal teams build strong, evidence-backed arguments.

We assist in cases involving:

• Property damage from fallen trees or limbs
• Personal injury due to unsafe conditions 
• Tree ownership and boundary disputes
• Tree removal or negligence claims
• Insurance claims and valuation disputes
• Land use, zoning, and preservation conflicts

Why You Need an Arborist Expert Witness

Clarify Complex Tree Issues
Legal teams often lack the technical background to interpret arboricultural evidence. We explain growth patterns, structural defects, disease conditions, and risk factors in plain language, backed by scientific reasoning.

Unbiased, Credible Testimony
As neutral third parties, our assessments are based on facts—not personal interests. That objectivity lends credibility in court and ensures fair outcomes.

Support Legal Strategy with Technical Precision
From preparing thorough reports to anticipating cross-examination, our expert witnesses are trained to uphold the highest standards of professionalism, ethics, and documentation.
