In plain English
Assignment clauses control whether a party can transfer the contract; change-of-control clauses treat a sale, merger, or financing as a transfer even when the entity stays put. For startups, anti-assignment language can block a fundraise, acquisition, or simple affiliate reorg unless you carve those events, or get consent you cannot time.
Not legal advice. Financing, M&A, and anti-assignment outcomes depend on the whole contract and governing law. Escalate material deals to a licensed attorney.

What is an assignment clause?
Assignment is the transfer of rights, obligations, or both under a contract to someone else. An anti-assignment clause limits that transfer, often "neither party may assign without prior written consent."
On a startup MSA, this sits with the "boilerplate" that is not boilerplate. Customers avoid waking up with a different vendor; vendors stop a logo flipping the paper to a competitor. The trap is asymmetry plus silence on events you plan to have: priced rounds, a sale, a parent flip, a security interest. Run it with the Startup MSA redline checklist, if you only fight liability, you optimized the wrong year of the company.
What is a change of control clause?
Change of control (CoC) defines a triggering event (typically a sale of voting power, merger, or sale of substantially all assets) and then attaches a consequence: consent required, termination right, or automatic assignment.
That is why CoC is the acquisition cousin of assignment. A stock sale may leave the same legal entity on page one of the MSA. If the clause only bans "assignment" and never defines CoC, a buyer may still inherit the contract. If the clause says CoC counts as assignment, or gives the customer a walk right on sale, your LOI just grew a consent scavenger hunt.
Why do these clauses matter in a raise or a sale?
Because the other side's paper becomes your deal friction at the worst time.
Acquisition / LOI week. Buyer diligence asks which customers can terminate or withhold consent on CoC. "Not unreasonably withheld" is homework. Absolute prohibitions plus termination-on-sale is a price chip, or a walk. Asset deals and mergers are not the same as stock deals; map the clause to the actual structure with counsel.
Financing. Investors and lenders care whether material contracts are assignable or pledgeable. A ban "including by operation of law or as collateral" can collide with a facility you have not shopped yet. A CoC definition that treats a new majority holder as a trigger can turn a priced round into a customer-notification festival.
Ordinary growth. Affiliate assignment is how a parent/OpCo reorg happens. If the clause forbids even that, a "simple reorg" waits on twelve signature packets.
Read the trigger and the remedy before you treat the section as furniture.
What are the anti-assignment traps for startups?
| Pattern | What it often does | Founder/ops tell |
|---|---|---|
| Consent required; no exceptions | You need a signature to move the contract | Fine for them assigning to a competitor; painful for your sale |
| Consent, "not unreasonably withheld" | Consent still required, but delay has a standard | Better; still a calendar risk in M&A |
| Affiliate carve-out only | Reorgs easier; sale of the company still stuck | Check whether "affiliate" survives CoC |
| Sale / merger / "operation of law" carve-out | Classic seller ask | Confirm it covers stock and asset deals you might run |
| CoC = termination for convenience | Customer can walk when you get bought | Material revenue at risk; escalate |
| One-way: they may assign, you may not | Named-account lock-in | Push mutual or carve your M&A events |
| Order form inherits a nasty MSA | Child doc looks harmless | Read the parent (MSA vs SOW vs order form) |
Sharp truth: Optimistic email filenames are where this language hides. Track Changes exists so "including change of control" does not appear between Friday and Monday.
How should founders review assignment and CoC without performing law?
Use an ops pass, then escalate anything that touches a sale, a pledge, or an account you cannot annoy.
Review checklist
- Who may assign, both parties, or only the bigger logo?
- Is consent required, prohibited, or "not unreasonably withheld / delayed"?
- Are affiliates carved out? After a CoC, is the buyer an "affiliate"?
- Does "assignment" include merger, stock sale, asset sale, and operation of law?
- Is there a separate change-of-control definition? What % / which transactions?
- Remedy: void assignment, damages, or termination right?
- Notice-only vs consent. Notice still needs an owner and a template.
- Security interest / financing language present or banned?
- Do SOWs and order forms incorporate this section by reference?
Compare vendor paper with the vendor contract review checklist. On outbound MSAs, set a standard before the first redline (how to review an MSA without a lawyer).
What is a reasonable operational stance (not a legal opinion)?
Common (counsel-vetted) asks on your paper: mutual anti-assignment; carve-outs for affiliates and for merger, financing, or sale of substantially all assets; if they need a CoC consent right, prefer notice plus a time-boxed standard, not a silent veto. Watch termination-on-CoC the way you watch uncapped liability: a walk-away signal on material accounts.
On their paper: do not "accept boilerplate" because it is page 18. If they will not move, record the deviation as a decision with an owner. Future you, in a data room, would like a sentence that says you saw it.
