Legal Opinion Letter

Produces a formal opinion letter with structured sections: scope, factual recitation, legal analysis, calibrated conclusions, and qualifications. Ensures proper assumptions, citation standards, and reliance limitations.

Prerequisites

Gather before drafting:

1. Transaction description — structure, parties, purpose (M&A, financing, regulatory)
2. Governing documents — agreements, corporate records, certificates, resolutions
3. Jurisdictions — governing law and jurisdictions requiring analysis
4. Opinion recipient — client only or named third-party relying parties
5. Specific questions — enumerated legal issues the opinion must address
6. Exclusions — matters outside scope (tax, securities, antitrust, etc.)

Letter Sections

Draft the following sections in order:

1. Introduction

Firm letterhead, date, recipient, and "Re:" line. One paragraph identifying the relationship, transaction, and purpose.

2. Scope of Opinion

Number each legal question being answered. Explicitly exclude out-of-scope matters:

Excluded Matter	Note
Tax consequences	Advise client to consult tax counsel
Securities law compliance	Advise client to consult securities counsel
Antitrust / regulatory	Note if applicable
Business judgment / wisdom	Outside legal analysis
Laws of non-covered jurisdictions	Identify which are covered

3. Documents Reviewed

Enumerated list with full titles, execution dates, parties, and relevant sections.

4. Factual Background

Material facts only. Categorize each:

• Verified — confirmed through document review (cite document, section, page)
• Represented — accepted as client representations
• Assumed — assumed for purposes of the opinion (flag prominently)

5. Assumptions

Include standard assumptions (tailor as needed):

• Signatures genuine and authorized
• Documents authentic and complete; no undisclosed amendments
• Signatories had requisite corporate authority
• No oral modifications to written agreements
• Entities duly formed and in good standing
• No insolvency proceedings pending or contemplated
• No undisclosed facts affecting the analysis

6. Legal Analysis

For each scoped question: state applicable law with full citation, apply rule to facts, address counterarguments or ambiguities. Where authority is split, acknowledge directly and explain basis for preferring one line.

Citation standards:

• Statutes: current version; note pending amendments [VERIFY]
• Cases: confirm not overruled; note binding vs. persuasive; pinpoint cite
• Regulations: current CFR section and effective date
• Agency guidance: note persuasive (not binding) weight

7. Conclusions

Use calibrated language matched to confidence:

Confidence	Language
High (clear law, undisputed facts)	"It is our opinion that..."
Moderate (some ambiguity)	"It is our opinion that it is more likely than not that..."
Predictive (court outcome)	"We believe a court would likely conclude that..."
Conditional	"Assuming [X], it is our opinion that..."

Number conclusions parallel to the scoped questions.

8. Qualifications and Limitations

• Opinion as of the letter date; no duty to update
• Based solely on laws of specified jurisdictions as of opinion date
• Does not address laws of other jurisdictions
• Reliance limited to named recipient(s) / client only
• No distribution or reliance by others without written consent
• Subject to equitable principles, bankruptcy/insolvency law, public policy
• Subject to general principles limiting specific remedies

9. Signature Block

Attorney name, bar admission (jurisdiction, number), title, firm, contact. For firm opinions, clarify signing capacity and whether institutional.

Pitfalls

• Scope creep — never opine beyond enumerated questions; unsolicited opinions create unintended liability
• Certainty calibration — excessive hedging is as problematic as overstatement; use the table deliberately
• Citation verification — never cite from memory; mark uncertain citations [VERIFY]
• Third-party reliance — identify relying parties by name; time-limit reliance where appropriate
• Local counsel — if opining on a jurisdiction where drafter is not admitted, note basis for confidence
• Length — typically 3-10 pages; do not pad with background law that adds no analytical value
