1
What is a questioned document in forensic examination?
A document whose authenticity, origin, authorship, integrity, or other characteristics are disputed or require scientific examination.
2
What is the primary purpose of forensic handwriting examination?
To evaluate handwriting characteristics and determine whether the available evidence supports a common or different writer.
3
What is a known handwriting standard?
A handwriting specimen of established origin used for comparison with questioned writing.
4
What is a requested handwriting exemplar?
A specimen written by an individual specifically for comparison during an investigation.
5
What is a collected handwriting exemplar?
A preexisting handwriting specimen obtained from ordinary records or documents for comparison.
6
Why are contemporaneous handwriting standards valuable?
They may better represent the writer's habits and physical condition during the period when the questioned document was produced.
7
What is natural variation in handwriting?
Normal differences among writing samples produced by the same individual.
8
Why is natural variation important in handwriting identification?
A genuine writer does not reproduce every letter identically, so expected variation must be distinguished from meaningful differences.
9
What are class characteristics in handwriting?
Features commonly shared by groups of writers because of writing systems, instruction, or conventional letterforms.
10
What are individual handwriting characteristics?
Distinctive writing habits or combinations of features that may help distinguish one writer from another.
11
What is handwriting slant?
The general direction or angle of letter strokes relative to the writing baseline.
12
What is the baseline in handwriting examination?
The actual or imaginary line along which written characters are positioned.
13
What is letter spacing?
The distance and arrangement between successive letters in written text.
14
What is word spacing?
The distance between words, which may reflect a writer's habitual writing patterns.
15
What is relative letter proportion?
The relationship between the sizes of different letters or their component parts.
16
What is pen pressure in handwriting?
The force applied by the writing instrument to the writing surface.
17
What is line quality in handwriting examination?
The smoothness, continuity, and control of strokes, including features such as tremor, hesitation, and irregularity.
18
What is pen lift?
The point at which a writing instrument leaves the surface before writing continues.
19
What is a connecting stroke?
A stroke joining adjacent letters or parts of letters in connected handwriting.
20
What is a terminal stroke?
The stroke or movement used to finish a letter, word, or writing sequence.
21
What is a beginning stroke?
The initial pen movement used to form a letter or written character.
22
What is stroke sequence?
The order in which the component strokes of a written character or mark are produced.
23
What is retracing in handwriting?
A pen movement that follows or partially follows a previously written stroke.
24
What is patching in questioned handwriting?
A deliberate addition or correction of strokes, sometimes intended to improve the appearance of simulated writing.
25
What is disguised handwriting?
Writing intentionally modified by its author to conceal habitual characteristics or avoid recognition.
26
What is simulated forgery?
An attempt to reproduce another person's handwriting or signature by visual imitation.
27
What is traced forgery?
A forgery produced by following the outline of an existing writing or signature.
28
What is freehand forgery?
A forged writing or signature produced without direct tracing, usually through imitation or invention.
29
What is a genuine signature?
A signature actually executed or validly adopted by the person whose signature it purports to be.
30
What is a forged signature?
A signature falsely made or altered to represent authorization or execution by someone who did not provide it.
31
Why may a slowly drawn imitation signature exhibit poor line quality?
Careful copying can interrupt normal writing rhythm and produce hesitation, tremor, or unnatural stroke transitions.
32
Does the presence of tremor automatically prove that a signature is forged?
No. Tremor can also result from age, illness, medication, writing conditions, or other factors.
33
What is an indented writing impression?
A pressure impression transferred to one or more underlying sheets during writing.
34
What does ESDA stand for in forensic document examination?
Electrostatic Detection Apparatus.
35
What is the principal purpose of ESDA?
To visualize certain indented writing impressions on suitable documents without relying solely on visible surface marks.
36
What is a mechanical erasure?
Removal or disturbance of writing through physical abrasion, scraping, or rubbing.
37
What is a chemical erasure?
Removal or alteration of writing through chemical treatment that changes or removes ink or other marking material.
38
What is an obliteration in document examination?
Concealment of original writing by covering it with additional marks, ink, or other material.
39
What is an interlineation?
The insertion of additional writing between existing lines of a document.
40
What is an alteration in a questioned document?
A modification of original document content, such as changing numbers, words, dates, or other entries.
41
What is an addition in document examination?
Material inserted into a document after its original preparation, potentially changing its meaning or appearance.
42
What is a substitution in document examination?
Replacement of original document content or components with different material.
43
What is an infrared examination used for in questioned documents?
To evaluate differences in material response that may reveal certain inks, alterations, obliterations, or other features.
44
What is ultraviolet examination used for in questioned documents?
To observe fluorescence or absorption differences that may help detect alterations, security features, or differing materials.
45
Why must handwriting examiners distinguish observation from interpretation?
Observed features are the evidentiary basis, while conclusions require evaluation of their significance and limitations.
46
Scenario: A signature looks similar to a genuine specimen but contains slow, hesitant strokes and unnatural pen lifts. What should be considered?
Possible simulation, while also evaluating genuine variation, writing conditions, and other explanations.
47
Scenario: A document has a visibly scraped area where a date was written. What type of alteration may be present?
A mechanical erasure.
48
Scenario: A letter contains faint pressure impressions from writing on an earlier sheet. Which technique may help recover the impressions?
Electrostatic detection using ESDA, where the document and conditions are suitable.
49
Scenario: Two handwriting samples share the same general slant and letter style. Is that sufficient to identify one writer?
No. General similarities must be assessed with the full range of reliable handwriting characteristics and their variation.
50
Scenario: A disputed contract contains a handwritten amount that fluoresces differently from nearby writing. What is a scientifically appropriate interpretation?
The difference may indicate differing materials or conditions and warrants further examination; fluorescence alone does not prove fraudulent alteration.
