DJR Expert Guide Series, Vol. 874 — How to Authenticate Handwritten Items Without Signatures

Unsigned handwritten items present one of the most challenging problems in authentication because the evaluator cannot rely on signatures, initials, or attribution marks—only the physical and behavioral characteristics of the writing itself. Many people underestimate how much authorship evidence is embedded in handwriting rhythm, ink flow, pressure distribution, paper composition, and contextual logic. Forgers often exploit the absence of a signature by adding overwritten sections, tracing patterns, or using AI-assisted handwriting meant to appear natural. Without a structured forensic workflow, it becomes easy to misinterpret natural variation as forgery or overlook subtle inconsistencies that contradict authentic authorship. Understanding how to authenticate handwriting based solely on observable evidence is essential for accurate attribution.

DJR Expert Guide Series, Vol. 874 teaches you the complete, non-destructive workflow professionals use when evaluating unsigned handwritten documents, notes, journal entries, margin annotations, manuscript fragments, and other signature-free materials. You’ll learn how to analyze structural handwriting traits, study ink and instrument behavior, assess paper composition and aging patterns, evaluate contextual and linguistic clues, compare writing to known samples, detect tracing or AI-assisted forgeries, identify hybrid or altered documents, and determine when advanced forensic lab analysis is required.

Inside this guide, you’ll learn how to:

• Authenticate unsigned handwriting using structural forensic principles

• Analyze ink flow, pressure patterns, and writing-instrument indicators

• Evaluate paper grain, fiber composition, watermarks, and aging behavior

• Compare handwriting to known exemplars without relying on signatures

• Detect tracing, overwriting, substitutions, and AI-assisted forgeries

• Identify mixed-era documents or artificial additions

• Assess historical context, vocabulary, and internal clues

• Recognize when content significance matters more than authorship

• Determine when to escalate an item for advanced forensic testing

Whether you're reviewing historical notes, marginal annotations, manuscripts, journals, sketches, or family documents, this guide gives you the expert methodology needed to authenticate unsigned handwriting with confidence and precision.
