What We Do

Examine documents to determine whether they are authentic or if they have been altered, and to determine how they relate to a person, thing, event or time.


Authentication of documents by:

  • comparing handwriting and signatures to identify or eliminate a particular writer

  • comparing the pens, pencils, inks, paper and printing processes used to produce them

  • examining them to detect and decipher erasures, indentations and alterations
