2. Instructions and scope

I was instructed by [Redacted] to conduct a forensic document examination of one (1) questioned document, being a document purporting to be a signed [Deed of Variation] dated [Redacted] (the “Questioned Document”), together with four (4) known exemplar documents containing the disputed signatures (the “Known Specimens”).

The specific questions put to me were:

  1. Whether the signature appearing on the Questioned Document purporting to be that of [Mr A. B. Sample] was written by that person;
  2. If not, whether any characteristics of the disputed signature permit an opinion as to the identity of the writer;
  3. Whether the document exhibits any evidence of alteration, erasure, or other forensic irregularity.

This report is prepared for the purpose of proceedings in the [Supreme Court of New South Wales].

3. Expert’s declaration

I make the following declarations in accordance with the Expert Witness Code of Conduct contained in Schedule 7 of the Uniform Civil Procedure Rules 2005 (NSW) and Part 23 of the Federal Court Rules 2011 (Cth):

  1. I understand that my paramount duty is to the Court and not to any party to the proceedings.
  2. I have not been instructed to adopt or exclude any particular opinion or conclusion.
  3. I have made all enquiries which I believe are appropriate and no matter of significance which I regard as relevant has, to my knowledge, been withheld from the Court.
  4. I have prepared this report in conformity with the Expert Witness Code of Conduct.
  5. I am available to attend Court to give oral evidence if required.
4. Qualifications and experience

My full curriculum vitae is provided as a separate document. In summary:

  • Over 24 years of forensic document examination experience
  • Director & Lead Examiner, Signature & Handwriting Forensics Pty Ltd
  • Independent consultant to the Australian Federal Police
  • Official Member, The Australasian Society of Forensic Document Examiners (ASFDE)
  • Professional Member, Australia and New Zealand Forensic Science Society (ANZFSS)
  • Accepted as an expert in forensic document examination in the Supreme Court of NSW, District Court of NSW, Local Court of NSW, Federal Court of Australia, and the Federal Circuit and Family Court of Australia
5. Materials received and examined
Exhibit Q1
Questioned Document: [Deed of Variation] dated [Redacted], comprising two (2) pages, bearing a signature purporting to be that of [Mr A. B. Sample] on page 2. Received as a colour photocopy on A4 paper.
Exhibit K1–K4
Known Specimens: Four (4) documents bearing undisputed signatures of [Mr A. B. Sample], comprising: (K1) Passport application dated [Redacted]; (K2) Driver licence application dated [Redacted]; (K3) signed Statutory Declaration dated [Redacted]; (K4) executed contract of sale dated [Redacted].
6. Methodology

The examination was conducted in accordance with the ASFDE Code of Practice and established forensic document examination methodology. The following techniques were employed:

  1. Macroscopic examination — Visual inspection under controlled lighting using an inspection magnifier at up to 10× magnification
  2. Microscopic examination — Stereo-zoom microscopy at 10×–60× magnification for detailed assessment of pen pressure, ink distribution, line quality, and stroke characteristics
  3. Side-by-side comparison — Direct visual comparison of the questioned signature against known exemplars
  4. Overlay comparison — Digital overlay analysis using transparent image comparison to assess alignment of structural features
  5. Ink analysis — Non-destructive spectral examination using video spectral comparator (VSC) to assess ink composition and layering
7. Examinations conducted

7.1 Initial assessment

The Questioned Document (Q1) was received in good condition. The disputed signature appears on page 2 at the designated execution line. The signature was executed in blue ballpoint ink and measures approximately 52 mm in length and 12 mm in height.

The known specimens (K1–K4) contain signatures attributed to [Mr A. B. Sample] spanning a period of approximately [five] years. The known specimens exhibit a consistent range of natural variation consistent with genuine handwritten signatures.

7.2 Handwriting comparison

The questioned signature (Q1) was compared with the known specimen signatures (K1–K4) across the following parameters:

  • General form and arrangement: Overall size proportionality, slant, spacing, and positioning relative to the baseline
  • Letter formations: Specific construction of individual characters including initial and terminal strokes
  • Connecting strokes: Patterns of pen lifts, connections between letters, and fluency of movement
  • Pen pressure and shading: Distribution of pressure throughout the signature, variation in stroke width
  • Speed and fluency: Evidence of natural, rhythmic writing versus drawn, hesitant, or slowly executed movements
  • Line quality: Smoothness, continuity, and presence of tremor, patching, or retouching

7.3 Document examination

The document substrate and ink were examined for evidence of alteration, erasure, or any forensic irregularity. Observations were recorded under visible light, ultraviolet illumination, and infrared reflectance.

8. Findings and observations

8.1 Signature comparison

The following significant similarities and differences were observed between the questioned signature (Q1) and the known specimens (K1–K4):

Feature Observation Significance
General form The questioned signature broadly replicates the overall form and letter sequence of the known specimens Class characteristic — indicates the writer had knowledge of the general appearance of the genuine signature
Line quality The questioned signature exhibits evidence of drawn, hesitant stroke formation with periodic pen lifts inconsistent with fluent writing Individualising — strongly indicative of simulation (copying)
Pen pressure Uniform, heavy pressure throughout the questioned signature, lacking the natural pressure variation seen in known specimens Individualising — characteristic of traced or slowly executed simulation
Initial stroke The initial stroke direction and curvature differ from the known specimens; the known specimens show a consistent upward-left initiation absent in Q1 Significant difference
Letter ‘[B]’ formation The questioned signature constructs the letter ‘[B]’ with a closed loop structure; known specimens consistently use an open formation Significant difference — improbable in natural variation
Terminal stroke The questioned signature ends with a short, abrupt terminal; known specimens exhibit a tapered, descending terminal flourish Significant difference

8.2 Document integrity

Examination of the document substrate revealed no evidence of erasure, alteration, chemical washing, or ink obliteration. The document appears to be a single continuous production with no substituted pages or irregular binding. The ink of the signature is consistent with the ink used in the body text of the document.

9. Opinion

Question 1: Was the signature on the Questioned Document written by [Mr A. B. Sample]?

Opinion: Strong probability that the disputed signature was NOT written by [Mr A. B. Sample].

The questioned signature exhibits a combination of significant differences from the known specimens—specifically in line quality (drawn, hesitant formation), pen pressure distribution (uniform heavy pressure), initial stroke direction, and letter construction—that are collectively inconsistent with the natural variation observed within the known specimen set. The characteristics observed are more consistent with a simulated signature, produced by a person who had knowledge of the general appearance of the genuine signature but was not the genuine author.

Question 2: Do any characteristics permit an opinion on the identity of the writer?

The characteristics observed in the questioned signature are insufficient to identify the writer. The drawn, slowly executed line quality indicates simulation, but there are insufficient individualising features present to attribute the signature to a particular person. The simulation may have been produced by tracing or by careful freehand copying.

Question 3: Is there evidence of alteration or irregularity?

No evidence of alteration, erasure, or forensic irregularity was detected in the document substrate.

I confirm that I have made all enquiries which I believe are appropriate and that no matter of significance which I regard as relevant has, to my knowledge, been withheld from the Court. I am available to attend Court to give oral evidence and be cross-examined on the contents of this report if required.
