Antiques, art, and collectibles appraisal expert witness Lisa M. Barnes is co-owner of Thomas Charles Editions, LLC. She describes the professional appraisal process:

An appraiser uses a variety of tools: reference works, online electronic databases, and historical documents; and may consult with additional specialists in the field. Based on the analysis of the research, the appraiser produces an appraisal report detailing the appropriate valuation of your personal property.

It is best to get an appraisal before you need one. You will need an appraisal for:

There are several advantages to having your expert witness talk to the client directly. If your expert’s opinions will be based on the client’s observations and thoughts, the expert should meet and talk with that individual. For example, when the recollection of the plaintiff is crucial to the accident reconstruction expert witness’s opinion, and the plaintiff’s attorney fails to have his own expert meet the client, then the expert must rely on information the attorney gleaned at the deposition. If the expert only sees a summary of the client’s statement or deposition, there is no opportunity for the expert to ask pertinent questions directly.

After having researched and hired your expert witness, expect to give them the original or copy of every significant writing on which their opinion will be based. For example, in a neurology medical malpractice case, the neurology expert witness should be provided with complete copies of all the plaintiff’s medical records. While they may not have time to read all the records, the expert should be relied upon to determine which records are relevant. It may turn out that the expert finds relevant information in materials that the attorney believed to be of little value in his case.

Metallurgy expert witness Dr. R. Craig Jerner, Ph.D., PE, describes the metal failure analysis process:

The title, Metallurgical Failure Analysis, aptly describes the process, i.e., the analysis of a metal failure. In deference to my mechanical engineering friends, a metallurgist or metallurgical engineer is best equipped to analyze a metal failure. An accident or failure of a metal component, whether it is a simple consumer product such as a hammer or chisel, or a complex multi-component machine such as an airplane or a space shuttle, will normally not be a “simple” failure. Failures are normally complex. Often two, three or more separate but necessary circumstances or events are required to cause the failure or accident. Solving such a complex problem is much like solving a multi-piece jigsaw puzzle.

Guessing about a jigsaw puzzle picture from one or two puzzle pieces will usually lead you to a wrong conclusion. Guessing prematurely from one or two “facts” about the cause of a failure or accident will also usually lead to a wrong conclusion. A series of accident events and evidence will usually fit exactly with another set of events and evidence thereby allowing more of the true picture to be revealed.

Accident investigation expert witness Dr. R. Craig Jerner, Ph.D., PE, also specializes in metal failure analysis which he defines here:

Metallurgical Failure Analysis is a scientific process in which a cracked or fractured piece or weld is analyzed to determine the cause of failure. The metallurgical failure analysis process involves cutting samples from fractured or cracked samples, conducting a microscopic examination of the fracture or crack, cutting, mounting and polishing samples for scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), microstructural examination, microhardness testing and profiling, chemical analysis, etc. The goal of the process is usually to ascertain why the component cracked or fractured, i.e., causation of the crack or failure.

Admiralty & maritime expert witness Henry S. Woods, III has this to say on causation of maritime accidents:

Maritime accidents of all stripes – great and small – occur in a wide range of circumstances and conditions. The common thread that is usually found in the proper investigation and analysis of these accidents is not a sudden or mysterious failure of a system or item of equipment. Nor is it the lack of a properly functioning system or item of equipment. With the exception of product/vessel defects, the common cause of most maritime accidents are aspects of human error and human factors. The most crucial of these are:

Residential real estate expert witness Steve Cohen writes this on mold:

Most types of mold that are routinely encountered are not hazardous to healthy individuals. However, studies have shown that too much exposure to mold may cause or worsen conditions such as asthma, hay fever, or other allergies. Common symptoms of overexposure are cough, congestions, runny nose, eye irritation and aggravation of asthma. In those who are more vulnerable, more serious health effects such as fevers and breathing problems can also occur. Some molds produce chemicals called mycotoxins. Mycotoxins may cause illness in people who have sensitivity to them.

According to the EPA, “A major concern associated with exposure to biological pollutants is allergic reactions, which range from rhinitis, nasal congestion, conjunctival inflammation, and urticaria to asthma”. The most effective way to control mold is to control moisture. It is recommended that humidity levels be reduced to 30-60% to reduce the possibility of mold growth.

Residential real estate expert witness Steve Cohen writes this on mold:

Mold (fungi) can be found indoors and outdoors and is present everywhere. Of the more than 100,000 species of mold, at least 1,000 species are common in the U.S. Some of the most commonly found species are Cladosporium, Penicillium, and Aspergillus.

Molds reproduce by producing tiny spores. The spores float through the indoor and outdoor air continuously. When spores land on a damp area indoors, they may begin growing and digesting the material they have landed on in order to survive. Molds can grow on a variety of materials, but the most common are wood, paper, carpet and food. When excessive moisture or water accumulates indoors, mold growth often occurs.

Neurology expert witness Michael I. Shevell, M.D writes in “The Pediatric Neurologist as Expert Witness with Particular Reference to Perinatal Asphyxia,”

The situation in which a pediatric neurologist is most likely to be requested to act as an expert is that of a child whose impairment and resulting disabilities and handicaps are the result of an alleged perinatal asphyxia secondary to obstetrical management. Within this setting, the expertise of a pediatric neurologist is focused on the following four main issues:

1. Causation and precise determination of etiology-is asphyxia the root cause for the child’s observed disabilities?

The most common use of photographs in court are those that depict physical injuries, damage to automobiles, and the appearance of complex products and objects. While we are told that “the camera doe not lie,” it is also true that photographs can present distorted images, so be watchful for photographic techniques that tend to distort reality. A photography expert witness can help you determine which photographs are accurate and therefore likely to be admissible into evidence. These expert witnesses can explain photographic techniques that can be used to distort the appearance of objects.
