Therefore, look for collected standards executed close in time to the questioned document. This is especially critical in cases involving illness, death, accident, mental imbalance, substance abuse, or anything likely to cause a dramatic change in the subject's behavior. Find out everything possible about the circumstances under which the questioned document was allegedly prepared. Try to obtain standards written under similar conditions. If there was anything unusual about the materials of the questioned document, try to duplicate that uniqueness in the standards.
Content can be important in a document examination.
Look for collected standards that share letter combinations, words, phrases or numbers with the questioned document. When requesting standards prepare a text that will include such similar content. There is a method for obtaining good requested standards. In a handwriting case the material to be written should be dictated to the subject, rather than copied by the subject. Prepare the text and assemble the proper materials.
