Legal Due Diligence Checklist

A comprehensive legal due diligence checklist for M&A, fundraising, and partnership transactions. Used by corporate counsel and fractional GCs to organize document requests and surface deal risks early.

Legal due diligence for expert engagements covers ground that most companies do not think about until they run into a problem. The most commonly missed item in expert engagement agreements is intellectual property assignment — without an explicit IP clause, the consultant can retain rights to frameworks, methodologies, and deliverables they developed during the engagement. For companies raising capital, this creates a due diligence problem. This checklist covers the due diligence process for expert engagements: what documents to request, what clauses to include in every agreement, and what findings are common enough to be deal risks if not addressed before signing. Essential clauses: scope and deliverables (explicit, not vague), rate and billing terms (retainer vs. hourly vs. fixed), intellectual property assignment (all work product vests in the company), confidentiality and non-disclosure (survives termination for a defined period), termination (30-day mutual notice, no penalty, deliverables in progress prorated and transferred), and liability and indemnification provisions. Every expert engagement agreement should include explicit IP assignment language: "all work product created in connection with services under this agreement is work made for hire and vests exclusively in [Company]." Without this, the consultant can retain rights to frameworks and deliverables developed during the engagement.

Frequently Asked Questions

Intellectual property assignment. Most consulting agreements do not clearly specify that work product produced during the engagement vests in the company — not the consultant. Without this clause, the consultant can retain rights to frameworks, methodologies, and deliverables they developed during the engagement. For companies raising capital, this creates a due diligence problem. Every expert engagement agreement should include explicit IP assignment language — "all work product created in connection with services under this agreement is work made for hire and vests exclusively in [Company].

Three critical clauses beyond scope and rate: (1) IP assignment — work product vests in the company. (2) Non-compete scope — if you are in a sensitive market, a reasonable non-compete (not overreaching) protects your competitive position. (3) Termination — 30-day mutual notice, no penalty, deliverables in progress prorated and transferred. A fourth useful clause: exclusivity window (consultant cannot work with direct competitors for the duration of the engagement). This is not standard and must be negotiated, but it is reasonable for senior fractional executives.

Standard confidentiality: work product and company information kept confidential, no disclosure to third parties without written consent, survives termination for a defined period (typically 2–3 years for most business information). Add: a specific carve-out for publicly available information (confidentiality does not apply to information that is public knowledge), a prohibition on using company information to build competing products or services, and a definition of "confidential information" that includes financial data, customer information, strategic plans, and technical architecture.
