Actually, it&#8217;s a &#8220;forensic handwriting expert,&#8221; but the technical term is &#8220;forensic document examiner.&#8221; The specialty is handwritten items. We&#8217;re going to look at that signature and compare it to 40 other samples of that person&#8217;s signature from the last five or six years, preferably from around the same time period.<\/p>\n<h3>What We Look For<\/h3>\n<p><span style=\"font-weight: 400;\">If I were doing the case, I would do a side-by-side analysis. I would get a microscope. I would zoom in. From there, I would examine the little ink striations in the ink blobs. I would be looking to see whether this appears to be the same hand, with the same physiology and neurology, that signed the others.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are many telltale signs of forgery. I&#8217;m not going to list them here because I don&#8217;t want the forgers to know what exactly we&#8217;re looking for. In general, though, we&#8217;re looking for signs of forgery or signs of genuineness. Identifying those signs takes real expertise. I<\/span><span style=\"font-weight: 400;\">t&#8217;s a whole lot more difficult than looking at it and going, &#8220;Oh, it looks a little different.&#8221; Every little micro-movement of the pen has to be analyzed. Forensic document examiners typically charge $600 or $700 an hour.<\/span><\/p>\n<figure id=\"attachment_4579\" aria-describedby=\"caption-attachment-4579\" style=\"width: 864px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/bartbaggett.com\/blog\/wp-content\/uploads\/2026\/03\/art-baggett-forensic-document-examiner-signature-verification-forgery-detection-infographic.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-4579 size-full\" src=\"https:\/\/bartbaggett.com\/blog\/wp-content\/uploads\/2026\/03\/art-baggett-forensic-document-examiner-signature-verification-forgery-detection-infographic.jpg\" alt=\"Bart Baggett forensic document examiner infographic showing the science of signature verification and how forgery is detected.\" width=\"864\" height=\"482\" srcset=\"https:\/\/bartbaggett.com\/blog\/wp-content\/uploads\/2026\/03\/art-baggett-forensic-document-examiner-signature-verification-forgery-detection-infographic.jpg 864w, https:\/\/bartbaggett.com\/blog\/wp-content\/uploads\/2026\/03\/art-baggett-forensic-document-examiner-signature-verification-forgery-detection-infographic-300x167.jpg 300w, https:\/\/bartbaggett.com\/blog\/wp-content\/uploads\/2026\/03\/art-baggett-forensic-document-examiner-signature-verification-forgery-detection-infographic-768x428.jpg 768w\" sizes=\"auto, (max-width: 864px) 100vw, 864px\" \/><\/a><figcaption id=\"caption-attachment-4579\" class=\"wp-caption-text\">This infographic, aligned with the expertise of forensic document examiner Bart Baggett, breaks down the science behind signature verification \u2014 from microscopic ink analysis and comparative sampling to the neurological micro-movements that distinguish a genuine signature from a forgery.
