Alan M. Perlman, an academically trained career linguist, is a forensic expert who offers clients exceptional quality, experience, and expertise.  He is an academically trained linguist, one of a small number of linguistics experts who assist the legal professions. 


Like other forensic linguists, Dr. Perlman applies the principles and methods of linguistics to the language of legal proceedings and documents. (See Areas of Expertise below.)

He has a PhD in linguistics and more than 20 years of experience as an expert in forensic linguistics and the systematic analysis of language it requires.  His expertise represents a unique combination: a deep theoretical understanding of the workings of language...together with extensive experience in the application of linguistic principles to the analysis of language samples in order to assist attorneys, other legal professionals, law enforcement personnel, and others in understanding the linguistic issues that bear upon particular cases.

Dr. Perlman is a highly competent forensic expert witness who produces expert witness reports, depositions, and testimony that conform to the Daubert criteria and are legally and logically rigorous, as well as easily intelligible to both laymen and legal professionals.

Dr. Perlman's practice of linguistic forensics uses an original, multi-dimensional approach to stylistic analysis that incorporates traditional principles of stylistics -- but goes beyond language elements and uses a proprietary method to identify a wide range of stylistic similarities and differences.

Contact Dr. Perlman



Contracts, wills, or other binding documents: Dr. Perlman analyzes specific words, phrases, clauses, sentences, and other units, including the entire document, to offer informed judgments on clarity, comprehensibility, and (un)ambiguity.

Case example: A man suffered damages from defective rental equipment; he did not know that he had released the company from liability by signing a contract that was, in my judgment, too complex to understand.

Authorship: Dr. Perlman conducts analysis of a language sample-the grammar, lexicon, and other features - to offer an informed judgment of texts, in order to offer informed judgment on the authorship of anonymous, forged, or otherwise disputed documents.

Case examples: anonymous letters of complaint to a company’s Board; forged letters (by a single author) in employment dispute.

Plagiarism: Dr. Perlman examines texts to determine the likelihood of plagiarism.

Case example: The creator of an online course found it stolen and being offered by someone else. Dr. Perlman helped substantiate his charges.

Copyright/trademark: Dr. Perlman helps attorneys define the semantic points at issue, and he offers informed judgment on the genericity, specificity, and/or protectability of contested material. He also assesses the similarity of names/marks to offer informed judgments in infringement litigation.

Case example: Dr. Perlman demonstrated that another marketer’s brand name was, on several linguistic levels, similar to that of the attorney’s client.
