TL;DR: A change of control clause is the tripwire that can blow up your most important contracts the moment a deal closes. Acquirers routinely underestimate how many agreements contain these provisions - and discover too late that key licenses, customer contracts, or supplier arrangements are terminable on notice. The clause defines what constitutes a "change of control" (share transfers, mergers, asset sales, board composition shifts), then prescribes the consequences: consent requirements, termination rights, acceleration of obligations, or automatic assignment. Getting the definition wrong - too broad or too narrow - can either hand your counterparty a free exit or leave you exposed to a competitor stepping into your contractual shoes. Every M&A due diligence checklist should start here.
What Is a Change of Control Clause?
A change of control clause is a contractual provision that addresses what happens to the agreement when one party undergoes a significant ownership or governance change. At its core, the clause establishes two things: (1) a triggering event - the specific circumstances that constitute a "change of control", and (2) the contractual consequences that follow from that trigger.
The triggering events typically fall into several categories. Share or equity transfers occur when a specified percentage of voting shares or equity interests changes hands - commonly set at 50%, though sophisticated parties negotiate thresholds anywhere from 20% to 100%. Mergers and consolidations capture structural transactions where an entity ceases to exist or is absorbed into another. Asset sales address dispositions of all or substantially all assets. Board composition changes trigger when a majority of directors are replaced outside the ordinary course. And management changes - less common but seen in key-person-dependent arrangements - trigger when specified individuals depart.
The consequences range from mild to severe. At the permissive end, the clause may simply require notice to the other party. More commonly, it requires prior written consent before the transaction can close without breaching the agreement. At the restrictive end, the clause may grant an automatic termination right, accelerate payment obligations, or trigger put/call options on equity. In IP licensing contexts, the consequences can be particularly dramatic - a license may terminate entirely, reverting critical technology rights to the licensor.
Change of control clauses interact closely with anti-assignment provisions, but they are not the same thing. An anti-assignment clause prevents transfer of the contract itself; a change of control clause addresses changes in the identity or character of a party even when the contract technically remains with the same legal entity. This distinction matters enormously in stock acquisitions, where the contracting entity survives but its ownership changes completely.

"In the event of a Change of Control of Licensee, this Agreement shall automatically terminate effective upon the closing of such Change of Control transaction, unless Licensor has provided its prior written consent to the continuation of this Agreement, which consent may be granted, conditioned, or withheld in Licensor's sole and absolute discretion. For purposes of this Section, 'Change of Control' means any transaction or series of related transactions resulting in (a) the acquisition by any person or group of more than 30% of the voting securities of Licensee, (b) a merger, consolidation, or similar transaction involving Licensee, (c) a sale of all or substantially all of Licensee's assets, or (d) a change in the composition of Licensee's board of directors such that individuals who were directors as of the Effective Date cease to constitute a majority."
"Neither party may assign this Agreement or any rights hereunder in connection with a Change of Control without the prior written consent of the other party, such consent not to be unreasonably withheld, conditioned, or delayed. If a party undergoes a Change of Control without obtaining such consent, the non-changing party may terminate this Agreement upon 30 days' written notice. 'Change of Control' means any transaction resulting in a change in more than 50% of the voting power or equity interests of a party, a merger or consolidation in which such party is not the surviving entity, or a sale of all or substantially all of such party's assets. Notwithstanding the foregoing, internal reorganizations among Affiliates and public offerings of equity securities shall not constitute a Change of Control."
"This Agreement shall not be affected by any Change of Control of either party, and each party agrees that this Agreement shall continue in full force and effect following any Change of Control. For purposes of this Agreement, 'Change of Control' means the acquisition by a single unaffiliated third party of more than 50% of the voting equity of a party in a single transaction (excluding internal reorganizations, transfers among affiliates, equity financings, public offerings, and transfers to or among investment funds managed by the same sponsor). Each party shall provide written notice to the other party within 30 days following the closing of any Change of Control, but failure to provide such notice shall not constitute a breach of this Agreement."
Example Clause Language
"Licensee shall not undergo a Change of Control without providing Licensor with at least 60 days' prior written notice. Licensor shall have the right, exercisable within 30 days of receiving such notice, to (a) consent to the Change of Control and the continuation of this Agreement on its existing terms, (b) consent to the Change of Control subject to revised pricing and terms to be negotiated in good faith, or (c) terminate this Agreement effective upon the closing of the Change of Control transaction, in which case Licensor shall refund any prepaid and unused fees on a pro rata basis. If the acquirer is a Competitor (as defined in Exhibit C), Licensor may terminate this Agreement upon written notice without obligation to refund any fees."
"Upon the occurrence of a Change of Control, the Borrower shall promptly notify the Administrative Agent, and each Lender shall have the right to require the Borrower to prepay all outstanding Loans, together with accrued interest and all other amounts owing hereunder, within 30 days of such Change of Control. A 'Change of Control' shall be deemed to occur if (i) any person or group becomes the beneficial owner of more than 35% of the outstanding voting stock of the Borrower, (ii) during any period of 12 consecutive months, individuals who at the beginning of such period constituted the Board of Directors cease to constitute a majority thereof, or (iii) the Borrower consolidates with or merges into any other entity, or any entity consolidates with or merges into the Borrower, unless the Borrower's shareholders immediately prior thereto hold at least 50% of the voting power of the surviving entity."
"If either Party undergoes a Change of Control, the other Party (the 'Non-Changing Party') shall have the right, exercisable within 90 days of receiving written notice of such Change of Control, to (a) purchase the Changing Party's interest in the Joint Venture at Fair Market Value determined in accordance with Section 12.3, or (b) require the Changing Party to purchase the Non-Changing Party's interest at Fair Market Value plus a 15% premium. If the Non-Changing Party does not exercise either option within the 90-day period, this Agreement shall continue in accordance with its terms, provided that the Changing Party's Confidential Information obligations under Section 8 shall be deemed to extend to the acquirer and its affiliates."

Jurisdiction Notes
United States: Change of control clauses are generally enforceable in the US, but courts scrutinize them under state contract law principles. Delaware courts, critical for M&A, have generally upheld broadly drafted change of control provisions, though they may limit "sole discretion" consent rights if exercised in bad faith. Under the UCC, anti-assignment provisions are construed narrowly (UCC § 2-210), and courts distinguish between delegation of duties and assignment of rights. In the government contracting context, FAR Subpart 42.12 imposes specific novation requirements when a contractor undergoes a change of control, and certain contracts (especially classified or ITAR-controlled) require prior government approval. State franchise laws in many jurisdictions impose statutory restrictions on the effect of change of control provisions in franchise agreements, sometimes overriding contractual termination rights.
United Kingdom: English law generally enforces change of control provisions as drafted, subject to general principles of contractual interpretation. The UK Takeover Code imposes additional requirements in the context of public company acquisitions - contractual provisions that could frustrate a takeover bid may be challenged under the Code's "no frustrating action" principle. In government contracts, the UK's Procurement Act 2023 introduces specific rules around change of control in public contracts, including obligations to notify the contracting authority and potential termination rights. For IP licenses, English courts have held that a bare patent or copyright license is personal to the licensee and does not automatically transfer on a change of control, absent express language to the contrary.
European Union: Change of control provisions in the EU must be considered in the context of the EU Merger Regulation (ECMR), which establishes a mandatory notification and approval regime for concentrations meeting specified turnover thresholds. Contractual change of control triggers should be aligned with the ECMR definition of "concentration" to avoid gaps or overlaps. Under the GDPR, a change of control involving the transfer of personal data processing activities may trigger obligations to update data processing agreements and notify data subjects. In regulated sectors (banking, insurance, telecommunications), EU member state laws typically impose additional regulatory approval requirements that layer on top of contractual provisions. French law, for example, provides statutory protections for commercial agents that may limit the enforceability of certain change of control termination rights. German courts have occasionally held that change of control termination rights must satisfy the general prohibition on unreasonable contractual terms under § 307 BGB, particularly in standard-form contracts.
