# Legal Merger and Acquisition Review

Legal review of a merger or acquisition (M&A) covers the structuring,
investigation, and approval process for one company acquiring or
combining with another — a transaction context where
[[legal-due-diligence]] and [[legal-corporate-governance]] concerns are
especially concentrated and high-stakes.

## Key stages

- **Deal structuring** — deciding the transaction's legal form (asset
  purchase, stock purchase, merger), which has significant implications
  for liability transfer, tax treatment, and required approvals.
- **Due diligence** — investigating the target's legal, financial, and
  operational standing (see [[legal-due-diligence]]) before finalizing
  terms.
- **Definitive agreement** — negotiating and drafting the purchase
  agreement, including representations, warranties, and post-closing
  indemnification terms.
- **Regulatory approval** — depending on the transaction's size and
  industry, antitrust or other regulatory review may be required before
  closing.
- **Closing** — executing the final transfer of ownership/assets and
  satisfying any closing conditions.

## Why structure matters so much

The legal structure chosen for a transaction (asset vs. stock deal, for
instance) has major consequences for which liabilities transfer to the
buyer, how the deal is taxed, and what approvals (shareholder,
regulatory) are required — this is typically one of the earliest and
most consequential decisions in the whole process, not a mere technical
detail.

## Common pitfalls

- **Underinvesting in due diligence under deal-timeline pressure** —
  see [[legal-due-diligence]]'s own caveat on this; M&A due diligence
  carries especially high stakes given transaction size.
- **Overlooking required regulatory approvals** — closing a transaction
  that required antitrust or other regulatory clearance without
  obtaining it can unwind the deal or trigger penalties.
- **Ambiguous or thin representations and warranties** — the buyer's
  main post-closing protection against undisclosed problems comes from
  well-drafted representations and warranties; vague ones offer little
  real recourse.
- **Neglecting corporate governance formalities during the
  transaction** — proper board and shareholder approval processes (see
  [[legal-corporate-governance]]) matter for the transaction's own
  validity, not just as background compliance.
