What Makes a Signature Look Forged? 10 Red Flags Anyone Can Spot Before You Even Call an Expert
Most forged signatures don’t require a microscope to look suspicious — they reveal themselves in the very first glance.
And while a full forensic analysis is always the gold standard, there are early red flags anyone can look for before hiring an expert.
Below are 10 beginner-friendly indicators that often show up in forged signatures. These are the same early clues that attorneys, paralegals, real-estate professionals, and families bring to me when they suspect something is off.
⸻
1. The Signature Looks “Drawn” Instead of Written
Real writing flows.
Forged writing hesitates.
If the signature looks carefully sketched, overly neat, or unnaturally slow, that’s a major warning sign.
⸻
2. Wobbly or Shaky Stroke Quality
Fraudsters shake when they trace.
Authentic signatures have momentum and rhythm.
Look for tremors, uneven curves, and lines that don’t feel confident.
⸻
3. Pen Lifts in Strange Places
Most people sign in one continuous movement.
When a forgery has odd breaks, random restarts, or multiple pen lifts, that usually means someone was stopping to “check their work.”
⸻
4. The Size or Spacing Looks “Off”
People are consistent — even when signing quickly.
If this signature is suddenly:
• bigger
• smaller
• squeezed
• stretched
• poorly spaced
…it may not be theirs.
⸻
5. Unnatural Slow Speed
A slow signature has heavier ink deposits, darker curves, and sometimes a blunt ending stroke.
Slow = suspicious.
⸻
6. The Angle or Slant Doesn’t Match
Most adults write with a fairly consistent slant.
When a signature suddenly leans in a new direction, it may be because someone unfamiliar with the writer’s natural slant recreated it at the wrong angle.
⸻
7. Overly “Perfect” Matching
A real signature never looks exactly like another.
Even your own signatures vary.
A suspicious red flag is when a signature looks like a copy-paste version of another — meaning someone traced or lifted it.
⸻
8. Poor Line Quality
Forgeries often show:
• uneven pressure
• scratchy entry/exit strokes
• blunt endings
• inconsistent ink flow
Authentic writing is smooth, natural, and confident.
⸻
9. Different Pen Pressure
Real signatures rise and fall with natural pressure changes.
A forgery may show:
• flat, same-pressure strokes
• forceful “carved” pressure
• weak, hesitant pressure
Pressure doesn’t lie — and it’s one of the first things we check in court.
⸻
10. It Just Looks “Wrong”
Trust your instinct.
If something about the signature feels off — the style, rhythm, proportions, or energy — there’s usually a reason.
That intuition is what leads most clients to my office long before they understand why the signature looks wrong.

These indicators don’t replace a forensic examination — but they help you decide when it’s worth getting an expert involved.
