Consent Requirements

Consent Requirements is a legal and regulatory term relevant to M&A transactions — governing contract rights, regulatory approvals, or post-close obligations.

Last updated: April 2026

Full Definition

Consent requirements in M&A refer to the need to obtain approval from a third party before a transaction or specific element of a transaction can proceed. These requirements arise from contractual provisions (anti-assignment clauses, change-of-control provisions), regulatory obligations (government filings, agency approvals), and statutory requirements (shareholder votes, board approvals). Consent requirements are one of the most common sources of closing delay and deal complexity.

Contractual consents: The most frequent consent requirements come from commercial contracts. Leases typically require landlord consent to assignment. Government contracts require agency novation. Software licenses require licensor consent to transfer. Customer and supplier agreements may include both anti-assignment and change-of-control provisions. Each material contract must be reviewed, the consent obligation identified, and a plan developed for obtaining it or addressing the risk if it's withheld.

Regulatory consents: Depending on the industry and transaction, regulatory consents may be required from: antitrust authorities (HSR filing and clearance), foreign investment review bodies (CFIUS), state insurance regulators (change of control of licensed entities), state gaming regulators, healthcare licensing boards (Medicare/Medicaid enrollment transfers), securities regulators, and banking regulators. Regulatory consent requirements have firm timelines and processes — unlike contractual consents, you cannot simply negotiate around them.

Shareholder and board consents: Corporate acquisitions require board approval from both the buyer and the seller. Mergers typically require shareholder approval by the target. Acquisitions above certain dollar thresholds may require acquirer shareholder approval as well. These internal governance approvals must be obtained through the proper procedural mechanisms — board resolutions, proxy statements for shareholder votes — and documented precisely.

Managing the consent process: Best practice is to identify all consent requirements in the first week of diligence, categorize them by difficulty and materiality, and begin outreach immediately for the most difficult or time-consuming ones. Build consent timelines into the overall deal timeline — identifying in advance that a government contract novation takes 90+ days prevents a surprise that delays closing at the eleventh hour.

Seller vs. Buyer Perspective

If you're selling

You own the relationships with your customers, landlords, and suppliers — consent outreach should come from you, not from the buyer alone. Plan who will reach out to each counterparty, when, and what they'll say. Some counterparties will use the consent request as leverage to renegotiate terms — brief your buyer before you approach these parties so there are no surprises. If a key consent is unlikely to be obtained (a difficult landlord, a strategic customer who won't grant consent to a competitor-affiliated buyer), disclose this risk to the buyer early rather than letting it surface mid-process.

If you're buying

Integrate consent tracking into your diligence project management from day one. Assign specific responsibility for each consent to a named team member. Set interim check-in dates — don't wait until the week before closing to discover that a critical consent is stuck. For consents that require regulatory filings (not just counterparty approval), understand the regulatory agency's actual processing timeline and build in buffer. Have a contingency plan for any consent that may not arrive before your outside date.

Real-World Example

An acquisition requires consent from four parties: (1) the primary landlord (obtained in 10 days after routine review), (2) the city government for an existing service contract (obtained in 18 days through an expedited process), (3) the company's ERP software vendor (initially refused, then granted after the buyer committed to a 3-year renewal), and (4) a key supplier with a change-of-control provision in their supply agreement (resolved by the buyer's parent company providing a guarantee). The most complex consent — the ERP vendor — took 5 weeks and required modifying the deal structure to include a software licensing commitment.

Why It Matters & Common Pitfalls

  • !Early identification beats late scrambling. The most expensive consent problems are discovered 3 weeks before a planned closing date. Audit all material contracts for consent requirements in the first week of diligence — not as a closing task.
  • !Counterparties can use consent as leverage. A landlord who learns about an acquisition may demand lease modifications as a condition of consent. A key customer may use the consent request to accelerate pricing discussions. Anticipate these negotiation dynamics and prepare your strategy before approaching each counterparty.
  • !Assuming stock deals avoid consents is dangerous. Change-of-control provisions in contracts trigger even in stock deals, where no formal assignment occurs. Review all material contracts for change-of-control language regardless of deal structure.
  • !Government contract novations are slow. Federal government contracts require a formal novation agreement among seller, buyer, and the contracting agency — a process that routinely takes 60–120 days and requires agency legal review. Factor this timeline into any acquisition involving government prime contracts or significant subcontracts.
