CaseMark 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:
- Transaction description — structure, parties, purpose (M&A, financing, regulatory)
- Governing documents — agreements, corporate records, certificates, resolutions
- Jurisdictions — governing law and jurisdictions requiring analysis
- Opinion recipient — client only or named third-party relying parties
- Specific questions — enumerated legal issues the opinion must address
- 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
