Why Assignment and Change of Control Provisions Matter
You chose your vendor, your partner, or your customer for a reason. Maybe it was their team, their technology, their financial stability, or their market position. An assignment or change of control provision determines whether the party you evaluated is the one you’ll be working with for the life of the agreement, or whether that relationship can be transferred to someone else without your input.
These clauses tend to get less attention than pricing or liability during negotiations. That’s a mistake, particularly for companies in growth mode where acquisitions, mergers, and restructurings happen on both sides of the table.
What Assignment Means in a Commercial Contract
Assignment is the transfer of a party’s rights, obligations, or both under the agreement to a third party. Without a restriction, most contract rights are assignable under common law. That means the counterparty you vetted during procurement could transfer your agreement to an entity you’ve never evaluated, and you may have no right to object.
An anti-assignment clause changes that default. It typically requires the non-assigning party’s prior written consent before the agreement can be transferred, and it often includes a standard that consent will not be unreasonably withheld, conditioned, or delayed.
From the assigning party’s perspective, restrictions on assignment can create real problems. Companies restructure, form new subsidiaries, spin off business units, and get acquired. A blanket prohibition on assignment without consent means every internal reorganization requires the counterparty’s permission, which gives the other side leverage it did not bargain for and can slow down transactions that have nothing to do with the underlying contract.
The tension is legitimate on both sides. The non-assigning party wants to know who it’s doing business with. The assigning party needs operational flexibility.
A Different Trigger, Similar Concerns
A change of control provision addresses situations where the legal entity stays the same but its ownership changes. The company you contracted with is acquired, merges with another entity, or undergoes a shift in majority ownership. The contract remains between the same two legal entities, so a standard anti-assignment clause may not apply. A change of control provision fills that gap.
Buyers and customers typically want a change of control right because they do not want to discover that their vendor is now owned by a competitor, a private equity firm with different service priorities, or an entity with a weaker financial position. If the reason you chose the vendor was its team and culture, a change in ownership can alter everything about the relationship without changing the name on the agreement.
Vendors and other assigning parties push back on these provisions for understandable reasons. Change of control clauses can reduce a company’s acquisition value, create friction during M&A transactions, and give the counterparty a free option to renegotiate or exit the contract at the worst possible time. A buyer or customer who was otherwise satisfied with the relationship may use the change of control trigger to extract concessions or walk away from a below-market deal.
Common Approaches
Assignment restrictions generally fall into one of five structural categories, each reflecting a different balance between control and flexibility.
Consent required for all assignments: the strictest approach. No assignment without prior written consent. This gives the non-assigning party maximum control but creates friction for routine corporate transactions.
Consent required, with an exception for affiliates: allows assignment to a parent, subsidiary, or affiliate without consent, but requires consent for transfers outside the corporate family. This is a common middle ground that permits internal restructuring while protecting the counterparty from being handed off to a stranger.
Consent required, with an exception for mergers and acquisitions: allows assignment in connection with a merger, acquisition, or sale of substantially all assets without consent. This is the assigning party’s preferred position because it preserves deal flexibility. The non-assigning party loses the ability to control who ends up on the other side of the contract after a transaction.
Consent required, with a competitor carve-out: allows assignment without consent for most transactions but gives the non-assigning party a termination right if the assignee is a direct competitor. This addresses the most common concern—ending up in a contract with a competitor—without blocking all M&A activity.
No assignment restriction: uncommon in negotiated commercial agreements but sometimes seen in click-through terms. Either party can assign freely. The non-assigning party has no contractual protection.
The Details That Get Missed
Define “change of control” with precision. A provision that triggers on a “change in control” without defining the term invites disagreement. Does it mean a change in majority ownership? Voting control? Board composition? A merger where the company is the surviving entity? Spell it out. A common formulation is a change in more than 50% of voting power or a merger where the company’s pre-transaction shareholders hold less than 50% of the surviving entity.
Address what happens after assignment. Does the original party remain liable? Does the assignee assume all obligations? Is there a transition period? Silence here means the answer depends on applicable law, which may not align with either party’s expectations.
Consider the practical impact on the relationship. An anti-assignment clause protects you on paper. But if the other party’s key personnel leave after an acquisition, or the new owner deprioritizes your account, the clause does not fix the operational reality. Pair assignment restrictions with provisions addressing service levels, key personnel, and termination rights tied to material changes in the relationship.
Watch for “permitted transferee” language in financing transactions. Companies that use lending facilities or take on investors may need to assign contract rights as collateral. A blanket anti-assignment clause can interfere with financing. Consider a carve-out for collateral assignments that does not transfer day-to-day performance obligations.
