When your company is acquired, merges with another business, or goes through an internal restructuring, nearly every contract you have signed suddenly becomes relevant in a new way. The question is no longer just what the contract says about the deal at hand — it is whether that contract can continue at all, and on whose terms. Assignment and delegation clauses govern exactly this scenario, determining who has the right to transfer contract obligations or benefits to someone else, and under what conditions. Understanding these provisions before a transaction closes can mean the difference between a smooth transition and a contractual crisis.
Many business owners treat these clauses as routine boilerplate, scanning past them without much thought during the initial contract negotiation. That is a mistake. An assignment clause that seemed harmless when you signed a vendor agreement three years ago can give that vendor the right to block your merger or demand renegotiated terms as the price of consent. Conversely, a poorly drafted clause in your favor could prevent you from enforcing a valuable contract against a successor entity. These provisions have real teeth, and they matter most precisely when your business is at its most vulnerable — in the middle of a transaction.
Assignment vs. Delegation: Understanding the Distinction
The terms assignment and delegation are often used interchangeably in casual conversation, but they refer to legally distinct concepts. Assignment involves the transfer of contractual rights — the benefits you are entitled to receive under a contract. If you have a contract that gives you the right to receive software services, intellectual property licenses, or payment, those rights can potentially be assigned to another party. Delegation, on the other hand, involves the transfer of contractual duties — the obligations you are required to perform. When a company delegates its duties, it is asking someone else to step into its shoes and perform.
This distinction matters because the law treats them differently. Rights are generally more freely assignable than duties. Courts have long recognized that a party who is owed performance — payment, delivery of goods, provision of services — usually does not have a legitimate interest in who provides that performance, as long as performance is received. But when it comes to duties, the situation is more complex. If you contracted for personal services or for the judgment and skill of a specific individual or company, you have a real interest in ensuring that those duties are not delegated to a stranger without your consent.
In practice, most commercial contracts bundle both concepts into a single clause labeled assignment, which will typically read something like: ‘Neither party may assign this Agreement or delegate its obligations hereunder without the prior written consent of the other party.’ This combined approach is the most common, but it is also worth paying attention to whether the clause distinguishes between the two concepts, since that distinction can affect your rights in nuanced ways during a transaction.
Anti-Assignment Clauses and M&A Transactions
Anti-assignment clauses are clauses that require one party to get consent before assigning the contract. In the context of mergers and acquisitions, these clauses create significant complications because a change of control over one of the contracting parties may or may not constitute an assignment, depending on how the clause is written and how the transaction is structured. This is one of the most contested and nuanced areas of M&A contract law.
A merger or acquisition can take several forms: an asset purchase, a stock purchase, or a statutory merger. How an anti-assignment clause applies often turns on which structure is used. In an asset purchase, where the buyer acquires specific assets and contracts of the target company, contract rights and duties are explicitly transferred — this almost certainly triggers an anti-assignment clause. In a stock purchase, the target company remains a legal entity and no assignment of contracts technically occurs; the ownership of the entity changes, but the entity itself continues as the contracting party. Courts are divided on whether change-of-control provisions in anti-assignment clauses capture stock purchases.
Many sophisticated contracts now include explicit change-of-control provisions alongside or within assignment clauses. These provisions make clear that a change in ownership or control — even in a stock deal — triggers consent requirements. If you are a seller or a buyer in an M&A transaction, these provisions require careful analysis during due diligence. A contract with a change-of-control consent right held by the counterparty is a contract that requires negotiation or consent before closing. Failing to identify and address these provisions can result in contracts terminating by operation of their own terms on the closing date.
From the seller’s perspective, anti-assignment clauses in contracts you have with customers, suppliers, or partners represent a real risk that needs to be disclosed and managed. From the buyer’s perspective, they represent a liability that could affect the value of the deal. In practice, deal counsel will conduct a contract review specifically to identify all contracts requiring consent and develop a strategy — either obtaining consents before closing, structuring the deal to avoid triggering the clause, or assuming the risk that a counterparty will object after closing.
What to Negotiate: Key Drafting Considerations
When you are on the drafting or negotiating side of a contract, the assignment clause deserves real attention. The default position in many standard form agreements — no assignment without consent — may not serve your interests depending on the context. If you anticipate that your business may be acquired, restructured, or reorganized in the future, you want to think carefully about how this clause will operate in those scenarios.
One of the most important negotiating points is carving out affiliate assignments and corporate reorganizations from consent requirements. A well-drafted clause might read that assignment is permitted without consent to any affiliate, subsidiary, or parent, or in connection with a merger, acquisition, or sale of all or substantially all of the business to which this agreement relates. This language gives you flexibility to restructure internally and to complete transactions without being held hostage by counterparty consent. If the other side insists on consent rights, you can try to limit those rights to situations involving certain types of assignees — direct competitors, for instance — rather than a blanket consent requirement.
Another consideration is the automatic termination provision. Some contracts provide that any attempted assignment in violation of the clause renders the assignment void and may automatically terminate the contract. This is a harsh remedy and one worth pushing back on. A more balanced approach allows the non-assigning party to withhold consent or seek remedies for an unauthorized assignment, without causing automatic termination. Automatic termination provisions create unnecessary risk, particularly in transactions where multiple contracts must close simultaneously.
You should also pay attention to which party bears the burden after an assignment. Does the original contracting party remain liable as a guarantor of the assignee’s performance, or is the assignee substituted entirely? In many commercial contexts, the assignor should insist on being released from ongoing liability once the assignment is complete and the assignee has demonstrated creditworthiness. Maintaining ongoing guarantor liability undermines the purpose of the assignment in many restructuring scenarios.
Consent Standards: What Does Consent Not to Be Unreasonably Withheld Actually Mean?
Many assignment clauses include a qualification that consent will not be unreasonably withheld, conditioned, or delayed. This standard is meant to prevent a counterparty from using its consent right as leverage — demanding economic concessions or simply refusing to cooperate without legitimate reason. But what constitutes unreasonable withholding of consent is not always obvious, and disputes over this standard are common.
Courts have generally held that a party can reasonably withhold consent if the proposed assignee poses a materially greater credit risk, lacks the capability to perform the contractual duties, is a direct competitor, or has a history of litigation with the withholding party. What courts have been less willing to accept is a party withholding consent simply because it wants better commercial terms from the assignee or because the transaction benefits the assignor economically. Using a consent right as a renegotiation lever is the kind of conduct courts often find to be an unreasonable withholding.
If you are the party seeking consent, document your request thoroughly. Provide information about the proposed assignee’s financial condition, operational capabilities, and intent with respect to the contract. Make the consent request in writing early in the transaction timeline to allow adequate time for the counterparty to review and respond. If you receive a denial, request the reasons in writing. This documentation supports your position if the refusal is later challenged as unreasonable.
Restructuring Scenarios Beyond M&A
While M&A transactions attract the most attention in discussions of assignment clauses, internal restructurings — moving contracts between affiliated entities, spinning off a business unit, or reorganizing subsidiaries — raise the same issues. Many companies operate through complex structures involving parent companies, wholly owned subsidiaries, and related entities. Moving contracts among these entities, even when economically the same enterprise remains involved, technically implicates assignment provisions.
In bankruptcy and financial restructuring, assignment of contracts takes on particular significance under Section 365 of the Bankruptcy Code. A debtor in bankruptcy has the right to assume and assign executory contracts, notwithstanding anti-assignment provisions, subject to providing adequate assurance of future performance by the assignee. Anti-assignment clauses are generally unenforceable in bankruptcy to the extent they would prevent a debtor from maximizing the value of its estate. If you are a counterparty to a contract with a company that enters bankruptcy, this is a critical point: you may not have the consent rights you thought you had.
For companies that anticipate future growth through acquisition or that operate in industries with frequent restructuring, building flexibility into assignment clauses from the start is far more efficient than trying to renegotiate consent rights in the midst of a transaction. The cost of a well-crafted assignment clause at contract formation is negligible compared to the cost — in time, legal fees, and commercial disruption — of managing consent obligations across dozens of contracts when a transaction is pending.
Practical Takeaways for Business Owners
Assignment and delegation clauses are not boilerplate to be ignored. They are provisions that define the portability of your commercial relationships, and they will matter intensely the moment your business undergoes a significant change. Before signing any long-term or high-value contract, take the time to think about what your business might look like in three to five years. Are you a likely acquisition target? Are you planning to acquire others? Might you restructure into a holding company structure? These scenarios should inform how you negotiate the assignment clause.
When reviewing contracts as part of M&A due diligence, assignment and change-of-control provisions should be among the first items on your checklist. They can affect deal structure, timing, and value. Engage counsel early to identify which contracts require consent and to develop a plan for obtaining that consent or structuring the transaction to minimize risk.
Finally, remember that assignment clauses cut both ways. While you are focused on preserving your own flexibility, you should also consider whether your counterparties have the ability to assign their obligations to entities that may be less capable or less creditworthy than your original contracting partner. If the identity and capabilities of your counterparty matter to you — and in many commercial relationships they do — make sure your contract gives you adequate control over who can step into that role.
