Handwriting And Fingerprint Analysis
1. Handwriting Analysis
Handwriting analysis involves comparing disputed writings with known samples to determine authorship or authenticity. It is a form of expert evidence under Section 45 of the Indian Evidence Act, 1872.
Handwriting experts analyze:
Letter formation
Slant and spacing
Pressure patterns
Speed and flow
Peculiarities or abnormalities
Used primarily to:
Prove or disprove forgery
Authenticate signatures or documents
Detect alterations
Legal Status:
Expert opinion on handwriting is relevant evidence but not conclusive.
Courts require corroborative evidence to convict solely on handwriting opinion.
The expert must be acquainted with the person’s handwriting or have reliable sample documents.
2. Fingerprint Analysis
Fingerprint analysis is the scientific identification of individuals based on their unique fingerprint patterns.
Fingerprints are:
Unique to each individual
Permanent over life
Classifiable by patterns (loops, whorls, arches)
Used in criminal cases to:
Identify suspects
Link accused with crime scenes
Confirm identity in disputed cases
Legal Status:
Fingerprint evidence is considered highly reliable and admissible under Section 45.
Courts give significant weight to fingerprint evidence if collected and analyzed properly.
The process includes:
Collection of prints (latent prints)
Comparison with known prints
Expert opinion on matches

|---|---|---|
| Nature | Expert opinion under Section 45 | Expert opinion under Section 45 |
| Reliability | Not conclusive, requires corroboration | Highly reliable if proper procedures followed |
| Admissibility | Relevant but caution advised | Strongly admissible with scientific basis |
