Texas Tree Expert Witness

​

The Power of Evidence in Tree Law and Litigation

When a case involves trees — whether it’s property damage, storm loss, or a boundary dispute — what matters most isn’t opinion; it’s evidence. Understanding how that evidence translates into liability, valuation, or negligence requires specialized knowledge. That’s where I come in.

​

I’m Marty Shaw, a Certified Arborist, Consultant, Author, and Texas Tree Expert Witness. I’ve consulted on more than 500 cases across 24 states and have provided expert testimony in over 30 legal proceedings. My work focuses exclusively on tree-related litigation: valuation, investigation, and expert witness testimony. I don’t cut, trim, or remove trees — I clarify the facts.

​

Attorneys retain me because tree cases blend science and law in ways that few other disputes do. The structure of a trunk, the spread of a root system, the direction of a fracture — all of it becomes evidence. My role as a Texas Tree Expert Witness is to interpret those physical facts and present them in a clear, defensible way that aligns with Texas law and courtroom standards.

​

​

Why Attorneys Turn to a Texas Tree Expert Witness

Texas is home to a wide range of tree-related disputes. From storm damage in Houston and Dallas to boundary disagreements in Austin or rural property claims in West Texas, trees often sit at the center of cases involving property rights, negligence, and insurance coverage.

​

When attorneys call me, it’s because they need an independent, certified consultant who can help answer critical legal questions like:

• Who owned the tree, and who was responsible for its maintenance?

• Was a tree’s failure preventable, or was it caused by uncontrollable natural forces?

• Did construction, grading, or pruning create an unreasonable risk?

• What is the fair and defensible value of a tree that’s been lost or damaged?

• Was the standard of care met by the property owner, municipality, or contractor?

 

As a Texas Tree Expert Witness, I examine the evidence scientifically, document it objectively, and explain it in a way that judges, juries, and mediators can clearly understand. My findings become the backbone of legal arguments, helping attorneys move beyond speculation and into proof.

​

​

Understanding the Legal Landscape of Texas Tree Law

Texas tree law draws from common law principles and statutory frameworks related to property rights, negligence, and trespass. But the real challenge lies in applying those principles to the unique circumstances of each case.

​

For example, when a tree straddles a property line, ownership and responsibility may be shared. When roots or branches encroach onto neighboring land, the affected party may have rights to trim — but not destroy — the tree. And when a limb or trunk causes property damage, questions of negligence arise: Did the property owner know, or should they have known, that the tree was hazardous?

​

As a Texas Tree Expert Witness, I help attorneys interpret these issues through physical evidence. My reports address the structural, biological, and environmental realities of the tree in question, connecting them directly to legal elements like causation, foreseeability, and standard of care. The result is evidence that speaks clearly and stands firm in court.

​

​

The Importance of Causation in Tree-Related Litigation

Causation determines liability — and in tree cases, causation isn’t always straightforward.

​

Was it wind that brought the tree down, or root decay? Did construction sever roots, or was disease already weakening the base? As a Texas Tree Expert Witness, I answer these questions through systematic investigation.

​

I examine the tree’s structure, its root environment, and its historical maintenance to determine what triggered the failure. Attorneys then use my analysis to prove or disprove negligence. My goal is to make the cause of failure unmistakable — supported by measurable data, photographic documentation, and professional standards that withstand cross-examination.

​

In many cases, understanding causation transforms the argument. What might appear as an “act of God” can, under scrutiny, reveal years of deferred maintenance or overlooked warning signs. Likewise, I’ve helped defend clients against unfounded claims where evidence proved the failure was truly unavoidable.

​

​

Valuation and Damages Under Texas Law

Trees in Texas are considered part of real property — and when they’re damaged or destroyed, their loss has measurable economic and aesthetic value. Accurately quantifying that value requires formal appraisal, not guesswork.

​

As a Texas Tree Expert Witness, I use nationally recognized valuation standards, including the Guide for Plant Appraisal by the Council of Tree & Landscape Appraisers (CTLA). My appraisals factor in:

• Species, condition, and size

• Function and contribution to property value

• Replacement or restoration cost

• Location and utility

• Environmental and aesthetic benefits

 

Attorneys rely on my appraisals for cases involving wrongful removal, trespass, insurance disputes, and development damage. I prepare my reports with litigation in mind — clear, methodical, and backed by data. In mediation or trial, these valuations help establish fair recovery while adding professional credibility to your argument.

​

​

Negligence and Duty of Care in Texas Tree Law

Many of the cases I consult on involve claims of negligence — where a tree causes injury or damage and one party alleges that another failed to act responsibly. In these situations, my work focuses on whether a reasonable person, under similar circumstances, would have recognized the risk.

​

As a Texas Tree Expert Witness, I evaluate the evidence through the lens of duty of care. Were there visible defects such as decay, cavities, or lean? Did prior pruning or construction activities compromise stability? Were inspections conducted regularly, and if not, should they have been?

​

These findings often become the foundation for proving or refuting negligence. They help attorneys demonstrate whether the defendant met their obligation — or whether foreseeable danger was ignored.

​

​

The “Act of God” Defense and Insurance Implications

In Texas, where severe weather events are common, many cases hinge on whether damage resulted from negligence or from an unavoidable natural event. Insurance carriers and property owners often dispute where that line is drawn.

​

My work as a Texas Tree Expert Witness involves distinguishing between natural failure and preventable loss. I analyze structural integrity, decay progression, soil conditions, and prior damage to determine whether the event was foreseeable. When presented clearly, this evidence allows attorneys to challenge or defend “act of God” claims with confidence.

​

Insurance litigation also demands precision in valuation and causation — two areas where my expertise ensures that claims and defenses are built on verifiable, professional evidence.

​

​

Expert Testimony That Clarifies Complex Evidence

Attorneys don’t just need reports — they need experts who can communicate those findings effectively under oath. My experience testifying in more than 30 cases across multiple jurisdictions has taught me how to present complex arboricultural evidence in a way that’s both accessible and authoritative.

​

As a Texas Tree Expert Witness, I deliver testimony that focuses on clarity and neutrality. I’m not there to argue; I’m there to explain. Whether in deposition or at trial, I take technical details — from decay patterns to valuation formulas — and translate them into terms that judges and juries understand.

​

Attorneys appreciate that I maintain composure under cross-examination and that my testimony supports, rather than overshadows, their argument. My credibility stems from accuracy and professionalism — two qualities that matter most in the courtroom.

​

​

The Legal Significance of Certification and Experience

In expert witness work, credentials speak as loudly as conclusions. As a Certified Arborist through the International Society of Arboriculture (ISA), I follow the ANSI A300 standards and the CTLA methodologies recognized nationwide.

Certification ensures that my opinions are grounded in established scientific practice, not personal interpretation.

Over the years, I’ve also served as a consultant and author, sharing insights on tree law, valuation, and forensic arboriculture. Having been retained in more than 500 cases across 24 states, I bring both regional understanding and national perspective to every matter I handle.

​

When attorneys hire me as their Texas Tree Expert Witness, they know my work is admissible, credible, and consistent with the evidentiary standards of Texas courts.

​

Common Cases That Require a Texas Tree Expert Witness

Attorneys and insurers retain me for a broad range of cases involving tree-related disputes, including:

• Property line and ownership conflicts

• Root or branch encroachment

• Negligence or injury claims

• Wrongful removal and trespass valuation

• Construction and grading impacts

• Storm damage and insurance coverage

• Municipal or county tree liability

• Real estate disclosure or environmental compliance

 

Each type of case demands both biological expertise and legal precision. I evaluate physical evidence, site conditions, and maintenance records to connect the dots between science and responsibility. Attorneys then use my reports, depositions, and testimony to substantiate their case and reinforce credibility.

​

​

The Strategic Value of Early Expert Engagement

While I’m often retained after discovery begins, early involvement often produces better results. When brought in at the start of a case, I can help attorneys identify key evidence, preserve physical conditions before alteration, and structure technical questions for depositions.

​

As a Texas Tree Expert Witness, I frequently assist with:

• Reviewing case materials for technical accuracy

• Preparing interrogatories and expert discovery requests

• Creating demonstrative exhibits and graphics

• Providing rebuttal analysis against opposing experts

• Supporting mediation and settlement discussions with objective evidence

 

This proactive approach saves time, reduces uncertainty, and strengthens the foundation of your case long before trial.

​

​

The Importance of Neutrality and Credibility

In the courtroom, credibility is everything. I’ve built my reputation as a Texas Tree Expert Witness by maintaining neutrality and basing every opinion on evidence — not advocacy. Attorneys who work with me know that my testimony is balanced, consistent, and rooted in professional ethics.

​

This neutrality doesn’t weaken your case — it strengthens it. When an expert’s credibility is beyond question, their testimony carries more weight. I make sure every report I produce and every statement I deliver can stand on its own merits, regardless of who retained me.

​

​

National Experience, Texas Insight

While I’ve consulted across the United States, Texas has become one of the most active regions for my expert witness work. From Houston’s storm recovery cases to tree failure claims in San Antonio and property disputes in Dallas, I’ve seen firsthand how local soil conditions, climate, and ordinances affect outcomes under Texas Tree Law.

​

My nationwide experience allows me to bring consistency and professionalism to every case. Attorneys benefit from both my national standards and my familiarity with the unique challenges of Texas litigation — where weather, property rights, and rapid development all play major roles in tree disputes.
