What Is a Requested Handwriting Sample?

A requested handwriting sample is a handwriting specimen collected directly from a suspect, victim, or individual under controlled conditions for forensic examination and comparison with a questioned document. In forensic document examination, these samples help experts identify similarities or differences between known and disputed handwriting.

Unlike natural handwriting samples such as letters, diaries, or notes, requested handwriting samples are specifically produced on demand to match the style, format, and content of the questioned document.

Importance of Requested Handwriting Samples in Forensic Science

Requested handwriting specimens play a crucial role in:

• Forgery investigations

• Signature verification

• Fraud and cheque examination

• Anonymous letter analysis

• Legal and criminal investigations

• Document authentication

These samples help forensic document examiners evaluate handwriting characteristics such as letter formation, spacing, slant, pressure, rhythm, and natural variation.

Preparation Before Collecting Handwriting Samples

1. Legal Authorization

Before collecting a handwriting specimen:

• Obtain proper permission from legal authorities or the court if required.

• Ensure the collection process is legally documented.

• Include signatures of witnesses and the forensic examiner.

Proper legal authorization maintains the evidentiary value of the handwriting sample in court.

2. Subject Briefing

The individual providing the sample should be informed about:

• The purpose of the handwriting collection

• General instructions for writing

However, investigators should avoid revealing specific details of the questioned document to prevent intentional copying, disguise, or mimicry.

3. Environment Setup

For accurate forensic handwriting analysis:

• Seat the subject comfortably at a table

• Ensure proper lighting and minimal distractions

• Attempt to recreate the original writing conditions such as:

  • Sitting or standing position

  • Writing surface

  • Writing speed and posture

Matching environmental conditions improves the reliability of the comparison.

Procedure for Collection of Requested Handwriting Samples

1. Use Similar Writing Materials

The writing materials should closely resemble those used in the questioned document.

This includes:

• Similar pens, pencils, or markers

• Paper with similar texture, size, and format

Using comparable materials helps reproduce natural writing characteristics accurately.

2. Dictation of Content

The examiner should dictate writing content that includes:

• Uppercase and lowercase alphabets

• Numerals from 0–9

• Frequently occurring words and phrases

• Specific letter combinations from the disputed document

• Names, addresses, and sentences similar to the questioned text

Indirect dictation is preferred over showing the original document to avoid copying.

3. Collect Multiple Samples

Multiple handwriting specimens are necessary to study natural variations.

Recommended practices include:

• Collecting at least 15–20 repetitions

• Obtaining both cursive and printed writing styles if applicable

• Asking the subject to write:

  • Slowly

  • Normally

  • Rapidly

Variation in speed and style helps detect intentional disguise or unnatural writing behavior.

4. Use Blank Forms and Simulated Documents

If the questioned document involves a form, such as:

• Cheques

• Applications

• Receipts

• Contracts

Then similar blank forms should be recreated for the individual to complete. This helps reproduce spacing, alignment, formatting, and writing habits found in the original document.

Precautions During Handwriting Sample Collection

1. Preventing Handwriting Disguise

To minimize intentional disguise:

• Observe the writer carefully

• Use spontaneous dictation

• Change the order of dictated content

• Avoid allowing direct copying from the questioned document

Signs of disguise may include unnatural pen lifts, inconsistent slant, tremors, or unusual letter formations.

2. Health and Psychological Considerations

Certain physical and mental conditions may affect handwriting, including:

• Tremors

• Injury

• Medication effects

• Fatigue

• Stress or anxiety

These factors should be documented during collection because they may influence handwriting characteristics.

3. Proper Documentation

Every handwriting sample must include:

• Date and time of collection

• Location of collection

• Name and credentials of the examiner

• Signatures of witnesses

• Proper labeling of each sample

Maintaining an unbroken chain of custody is essential for admissibility in court.

Conclusion

Requested handwriting samples are an essential component of forensic document examination. Proper collection techniques, controlled conditions, and careful documentation help forensic experts accurately compare questioned and known writings. Following standardized procedures also ensures the reliability and legal admissibility of handwriting evidence in criminal and civil investigations.
