Examiner of Questioned Documents and Handwriting Expert

Linda L Mitchell is a forensic document examiner (sometimes referred to as a Questioned Document Examiner (QDE)), offering professional analysis of questionable documents at Forensic QDE Lab, llc in Southern California. Forensic document examinations are usually performed to either identify handwriting, analyze authenticity of documents, or determine if any alterations have been made. This scientific process requires a specific skill set of a professional document examiner – an expert in the field. The examination of a document can also include deciphering obliterated writing or erasures or determining the relative date of the document, among many other things. With her up-to-date laboratory, Linda is well equipped to handle most non-destructive examinations. Don’t hesitate to call her any time, including evenings and weekends, if you have questions about her services. Ms. Mitchell’s private practice in forensic document examination and analysis welcomes attorneys and law enforcement agencies for the identification of fraud, forgery, and document validity in both civil and criminal matters.
