Legal diligence is the lawyer-led audit of whether the company’s legal house is in order before money changes hands.

How it works

After a term sheet, investor counsel requests a data room: certificate of incorporation and amendments, cap table, option plans, prior SAFEs and notes, customer and vendor contracts, employment agreements, IP assignments, and any litigation or regulatory letters. Counsel flags missing board approvals, inconsistent vesting, or customer consent requirements on change of control.

Findings land in a disclosure schedule; serious items become closing conditions or indemnity topics.

Why it matters

• Founders: Run a mock diligence before fundraising. Fix IP assignment gaps and unsigned 83(b) elections early — they are cheap pre-round and expensive mid-deal.
• Investors: Legal diligence complements financial and commercial work. A clean legal report does not replace business diligence but prevents nasty post-close surprises.

Budget two to four weeks for legal diligence on a standard venture round; M&A can run months. Founders can accelerate by maintaining a living data room with indexed folders and a single point of contact for counsel questions.

Material contract review focuses on change-of-control clauses, exclusivity, IP ownership, and customer concentration — any customer representing large ARR share gets extra scrutiny.

Common mistake

Uploading unsigned drafts or outdated cap tables. Investors lose trust when the data room contradicts the pitch.

Practical takeaway

Maintain corporate hygiene continuously: signed IP assignments, board consents for option grants, and clean 409A history. Fixing issues during a live data room costs more and signals sloppy operations to investors.
