Spanning more than 30 years, Professor Eggington has been a consultant and expert witness in over 85 criminal, civil, federal and state cases including trade mark and contract language disputes, fraudulent and deceptive advertising and negotiations, assessment of English language proficiency, authorial attribution or author identification, hate crime determination and language policy legislation. He was an early adopter of corpus linguistics, or big data linguistic analysis within forensic linguistic contexts. This approach meets evidentiary standards. As such, he has been an instructor in many continuing legal education (CLE) events, including a workshop conducted for the Georgia State Superior Court. He has also been involved as either the lead linguist, or as a contributing linguist in a number of amicus curiae briefs submitted to the United States Supreme Court.

In recent years, since retiring in 2020 as emeritus professor of linguistics from Brigham Young University, Dr. Eggington has consulted on cases including: trademark infringement, alleged fraudulent or deceptive advertising, non-native English speakers' comprehension of their Miranda Waiver and police interrogation including a prominent case involving a foreign government official, the comprehensibility of a state's election ballots for the U.S. Department of Justice, the identification of the author of an amendment to a will, the meaning of a city civil code, and the meaning of a clause in an insurance policy.

In 2022, Dr. Eggington accepted a three-year appointment to the Model Utah Jury Instructions Civil Committee, under the direction of the Utah Judicial Council, Salt Lake City, Utah. This appointment requires that he analyze existing and future jury instructions in terms of their comprehensibility by jurors.

Originally from Australia, Dr. Eggington is an applied sociolinguist, a field that involves the study of how people use language in natural settings. He has co-edited six books and written one textbook that focus on the role of the English language, both nationally and internationally, and has authored numerous journal articles and book chapters in volumes published by major national, international and professional association presses. In addition to this work, he conducts research on matters involving language and the law. This forensic linguistic research has resulted in publications and presentations including:
