When Do You Need a Full Forensic Report vs. a Letter of Opinion?

Not every handwriting dispute requires a full forensic report.

Sometimes you need a formal document that can stand up in court.

Other times you simply need professional clarity before deciding your next move.

Choosing between a Letter of Opinion and a Full Forensic Report can save you time, stress, and thousands in legal fees. Below is a clear, attorney-friendly guide to help you understand exactly what each one is — and when you need which.

⸻

What Is a Letter of Opinion?

A Letter of Opinion is a concise, written summary of my findings after examining the questioned signature and comparing it to authentic known samples.

It is:

• faster

• less expensive

• highly informative

• ideal for out-of-court matters

• often used for negotiation, settlement, or personal clarity

This letter clearly states whether the signature is genuine, disguised, or likely forged, supported by the key reasons behind that conclusion.

Think of it as: the expert verdict without the courtroom paperwork.

When a Letter of Opinion Is Enough

You typically only need a Letter of Opinion when:

1. You’re deciding what your next legal step should be.

Attorneys will often use the letter to determine whether a case is worth filing.

2. You need clarity before getting involved with an estate or inheritance dispute.

Families often request this when settling internal disagreements.

3. You’re dealing with a contract, check, or agreement outside of litigation.

Many cases resolve before ever reaching court.

4. You need leverage during negotiations.

The letter provides official expert backing that gives your argument weight.

If your case never goes to trial, a Letter of Opinion is often all you need.

What Is a Full Forensic Report?

A Full Forensic Report is the formal, detailed, court-ready document that outlines:

• the methodology used

• side-by-side comparisons

• handwriting characteristics observed

• pressure patterns, slant, rhythm, pen lifts, speed variations

• scientific analysis and visual evidence

• the final expert conclusion

This report is built to withstand cross-examination and is accepted by courts, attorneys, mediators, and insurance companies nationwide.

Think of it as: the blueprint of the truth — built for the courtroom.

When You Need a Full Forensic Report

You should choose a full report when:

1. Your case is headed toward litigation.

Courts require formal documentation that follows strict forensic protocol.

2. Your attorney needs a document admissible as evidence.

Letters of Opinion are helpful, but full reports are what judges rely on.

3. Opposing counsel is likely to challenge the authenticity.

A formal report protects you against disputes, objections, and cross-examination.

4. You anticipate needing expert testimony.

A full report lays the foundation for any future deposition or testimony.

5. The financial stakes are high.

Estate cases, wills, real estate transactions, business agreements — they all benefit from the strength of a full forensic record.

If you’re going to court, you need the full report.
