Originals vs. Copies: Do You Need the Original Document for a Handwriting Examination?
One of the most common questions attorneys and private clients ask is also one of the most misunderstood:
“Do I need the original document for a forensic handwriting examination?”
The short answer: Originals are ideal — but high-quality copies can absolutely be examined, and solid conclusions can still be reached.
Here’s the long answer (and what your case actually requires).
⸻
1. Why Experts Prefer Originals
Original documents contain microscopic handwriting features that even the best scanner cannot fully capture.
Originals allow an examiner to evaluate:
• Stroke pressure
• Pen lifts and hesitations
• Natural rhythm and speed
• Pen indentation
• Line quality under magnification
• Retouching or patching
• Subtle tremor or unnatural construction
These are critical markers when determining authorship.
For high-stakes cases — estate disputes, contract fraud, real-estate filings, contested wills, loan agreements — originals provide the most complete foundation for an expert opinion.

2. When Copies Are Acceptable
Here’s the truth attorneys need to hear:
Most forensic handwriting cases today are completed using high-resolution digital scans.
Copies can be used when:
• The original is held by a court
• The original is held by opposing counsel
• The client only has access to a photocopy
• Time is limited
• The document is fragile or too valuable to ship
• The court will not release the original
In these scenarios, a certified examiner can still evaluate stroke patterns, spacing, proportions, slant, signature construction, and comparative features.
A strong, well-documented conclusion can still be issued.

3. What Cannot Be Evaluated on a Copy
There are certain features only visible on an original, including:
• Genuine pen pressure variation
• Micro-tremor
• Lift vs. drag
• Retouching marks
• Pen indentation (ESDA not applied on copies)
If these characteristics are critical to the case, the expert may recommend obtaining originals — but this is not required in every matter.

4. Why High-Resolution Scans Matter More Than “Copies”
The real issue isn’t copy vs. original — it’s quality vs. poor quality.
High-resolution scans (300–600 DPI):
• preserve stroke detail
• maintain proportion accuracy
• allow magnification without pixelation
• support reliable analysis
Low-resolution images, screenshots, or photographs taken at an angle may limit what an expert can conclude.
But even then, an examiner can often guide you on how to obtain usable images.

5. Court Admissibility: Does It Require an Original?
Another misconception:
Courts accept expert opinions based on copies all the time.
What matters is whether:
• The expert is certified and credible
• The methodology is sound
• The findings are well-supported
• The documentation is complete
If the original is available later for trial, the expert can update the opinion if needed — but this is rarely necessary.

6. Strategic Advice for Attorneys and Clients
Here is the best practice approach:
A. Start the examination with what you have.
Don’t delay a case because you’re waiting for an original.
B. Let the expert decide if the original is needed.
Most of the time, a solid conclusion can be reached without it.
C. If originals exist, secure high-resolution scans immediately.
D. If originals are controlled by opposing counsel, request inspection later.
You can still begin building your case today.
⸻
The Bottom Line
Originals are best — but copies are absolutely workable.
A qualified forensic document examiner can evaluate both, determine whether quality is sufficient, and guide you on next steps.
In litigation, waiting for the “perfect” document often wastes valuable time.
Start with what you have — and let the expert handle the rest.
