What to expect when you contact a forensic document examiner or specialist

  • Do not send any documents until requested. Your first inquiry should be general as to the type of work needed and the names of the parties involved so a conflicts check may be run. 
  • To retain the expert, a retainer payment and signed agreement is generally required. 
  • If the case involves a signature or handwriting question, gather several original documents with signatures (or handwriting, as applicable) dated close in time to the questioned document. Copies are acceptable, but original documents are preferred.
  • For the client's protection, the attorney should be the primary contact with the document expert. 
  • See our FAQ page for more general questions.
The American Society of Questioned Document Examiners is a nonprofit professional membership organization of forensic document examiners and specialists from all over the world. 

​The ASQDE was founded in 1942 and is the oldest and most prestigious organization of its kind.
