In this article, the forensic document examiners at Robson Forensic introduce the science of forensic handwriting analysis. They discuss the steps that a forensic document examiner follows, including analysis, comparison, and evaluation, and verification.
Included is a brief example comparing two handwriting samples, drawing attention to some of the key differences that a handwriting analyst may utilize in their analysis.
The science of handwriting analysis is based on the premise that no two individuals can produce exactly the same writing and that an individual cannot exactly reproduce his/her own handwriting due to writing variation. Variations are natural deviations that occur in a person’s handwriting.
The Process: Handwriting analysis involves a comprehensive comparative analysis between a questioned body of writing with a known body of writing. Specific habits, characteristics, and individualities in both the questioned known writings are examined for similarities and differences.
The handwriting examples below are from two different writers.
Structural differences (1) can be seen from the letter formations by each writer. Connecting strokes to letters (2) and slant (3) are visible and differ from each writer’s distinctive style. In addition, baseline alignment (4) is considerably unique whereas one writer consistently writes on the baseline and the other repeatedly deviates below the baseline.

Questioned document examination is a discipline within forensic science that pertains to documents with disputed authenticity or origin. A questioned document investigation is used to ascertain the authenticity (or lack thereof) of a document or other item when it comes into question. The examination of known to questioned documents provides analytical results regarding the similarities or differences between the samples using a variety of scientific principles and methods.
