Assignment Clause
Governs whether and how a party can transfer its contractual rights and obligations to a third party.
While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.
US Law · For business owners and foundersWhat is a Assignment Clause?
An assignment clause defines the rules for transferring rights and obligations under a contract to a third party (the "assignee"). Without specific restrictions, most contractual rights are assignable under US law - meaning a party can hand off their position in the contract to someone else without the other party's permission.
For business owners, assignment clauses matter most in two situations: when you want to prevent the other party from assigning their obligations to a less capable or reliable substitute, and when you are acquiring a business or being acquired and need to know whether key contracts transfer automatically or require consent.
In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.
Key Elements
Anti-Assignment Provision
A clause prohibiting either or both parties from assigning the contract without prior written consent. Common language: "Neither party may assign this Agreement without the prior written consent of the other party, which shall not be unreasonably withheld."Change of Control Carve-Out
Many contracts treat a merger, acquisition, or change of majority ownership as a deemed assignment, requiring consent even if the contracting entity technically remains the same. Critical to identify in any M&A due diligence.Permitted Assignments
Standard exceptions typically allow assignment to: affiliates and subsidiaries, successors in a merger or acquisition of all or substantially all assets, and lenders as collateral security for financing.Delegation of Duties
Assigning rights is different from delegating duties. A party can assign the right to receive payment but cannot delegate personal service obligations without consent, particularly where the original party was chosen for their specific skills.Effect of Prohibited Assignment
Under US law, an assignment made in violation of an anti-assignment clause may be void, voidable, or simply give the non-assigning party a breach of contract claim - depending on the specific language used and state law.Real-World Example
You sign a 3-year software development agreement with a boutique agency whose team you specifically selected. Six months later, that agency merges with a large offshore firm. The new parent company notifies you that the contract has been "assigned" to their offshore team.
If your contract has an anti-assignment clause with a change-of-control provision, you may have the right to terminate or withhold consent. Without one, the assignment likely proceeds - and the team you chose is replaced by one you did not. Always include a change-of-control trigger in service contracts where the specific team matters.
This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.
Sample Clause Language
Anti-Assignment with Change of Control and Permitted TransferWatch Out For
Change of control gaps
An anti-assignment clause that only covers voluntary assignments may not catch a change of control. Always add a specific change-of-control trigger if the identity of the other party matters to you.Consent "not unreasonably withheld"
This standard sounds protective but creates disputes. Courts have found all sorts of reasons to be "reasonable." If you truly need veto power over assignments, use "sole discretion" language instead.Collateral assignment to lenders
Many lenders require borrowers to collaterally assign key contracts as security. Your customer's contract with you may be assigned to their bank. Know when this is happening and what it means for your rights.Partial assignments
A party may try to assign rights to payment while keeping obligations, or vice versa. Specify whether partial assignments are permitted and under what conditions.Don't let assignment clause deadlines catch you off guard
Key dates tied to assignment clauses - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.
Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.
How to Use This in Your Favor
Include a change-of-control trigger
In any service or SaaS contract, define "change of control" broadly (acquisition of 50%+ of voting equity, merger, asset sale) and require your consent to continue the agreement under new ownership.Preserve your own right to assign freely
While restricting the other party, negotiate to keep your own assignment rights flexible - especially to affiliates, subsidiaries, and M&A successors. This protects your own future restructuring options.Specify consequences of prohibited assignment
State explicitly that any unauthorized assignment is void and gives the non-assigning party the right to terminate immediately. Ambiguous language creates uncertainty in enforcement.Protect key vendor relationships in M&A
Before any acquisition, audit all target company contracts for anti-assignment and change-of-control clauses. Missing these is one of the most common and expensive due diligence failures.Frequently Asked Questions
Are contract rights automatically assignable in the US?
Generally yes, unless the contract restricts assignment. Under US common law, most contractual rights can be assigned without the other party's consent. Exceptions include: personal service contracts where the specific party was chosen for their unique skills, and contracts where assignment would materially change the other party's obligations or increase their risk.
What is the difference between an assignment and a novation?
An assignment transfers rights (and sometimes duties) to a third party, but the original party may remain liable. A novation replaces the original party entirely with a new one, fully releasing the original party from all obligations. Novations require consent from all parties and are more comprehensive but harder to obtain.
Can I assign my contract as collateral for a loan?
Yes, collateral assignment is common in business financing. A borrower assigns their rights under a contract to a lender as security, but typically retains the right to continue performing and receiving benefits unless they default. Anti-assignment clauses often include an exception for collateral assignments to financial institutions.
