Assignment of Contract Rights

A contract is often more than just an agreement between two parties; it is an asset that can be transferred to others, unlocking value and enabling complex commercial transactions. Understanding how to properly assign contractual rights is crucial for anyone navigating business, real estate, or finance.

The Core Elements of an Assignment

An assignment is a transfer of a party's existing contractual rights to a third party, known as the assignee. The party transferring the rights is called the assignor, and the party who owes a duty under the original contract is the obligor. Upon a valid assignment, the assignee essentially steps into the assignor's shoes concerning the assigned right. This means the assignee gains the legal right to receive the obligor's performance and can enforce that right against the obligor.

For an assignment to be effective, the assignor must manifest a present intent to transfer the right immediately. This is not a promise to transfer in the future but an immediate transfer. No special language is required; any words that demonstrate an intent to transfer are sufficient. Crucially, the assignor does not need to notify the obligor for the assignment itself to be valid between the assignor and assignee. However, as we will see, notification plays a pivotal role in protecting the assignee from later claims.

Which Contract Rights Are Assignable?

The general rule is that contractual rights are freely assignable. This promotes economic efficiency by allowing rights, which are a form of property, to be transferred to those who value them most. However, there are significant exceptions where assignment would be ineffective or a breach of contract.

Rights are not assignable if the assignment would:

1. Materially Change the Obligor's Duty: Assignment is prohibited if it would significantly alter what the obligor must do, how they must do it, or to whom they must perform. For example, a right to receive custom-made artwork from a specific artist is personal and non-assignable, as the obligor's duty (the artist's unique skill and style) is materially altered.
2. Materially Increase the Burden or Risk: If assignment forces the obligor to perform in a different location, to a party with a different credit risk, or under significantly more onerous conditions, it will not be allowed.
3. Materially Impair the Chance of Obtaining Return Performance: This often arises in bilateral contracts where each party's performance is conditional on the other's. Assigning a right could undermine the obligor's expectation of receiving the assignor's reciprocal performance.
4. Be Validly Precluded by Contract: The contract itself may contain an anti-assignment clause.

Anti-Assignment Clauses and Their Limits

Parties often include anti-assignment clauses in contracts to control with whom they do business. The effect of such a clause depends on its wording and jurisdiction. A clause stating that "this contract shall not be assigned" or "assignment is prohibited" is generally interpreted as a promise by the parties not to assign. If a party breaches this promise by assigning, the assignment itself is typically still effective in transferring the right to the assignee. However, the assignor has breached the contract and may be liable for damages to the obligor.

Some clauses are more forceful, stating that "any attempted assignment shall be void." These are often called "invalidating" clauses. Many courts will enforce such a clause and deem an attempted assignment ineffective, leaving the assignee with no rights against the obligor. It is critical to read the specific contractual language. Furthermore, courts will not enforce an anti-assignment clause that constitutes an unreasonable restraint on alienation (the transfer of property), particularly for rights to the payment of money, which are highly assignable as a matter of public policy.

The Effect of Assignment: Duties, Defenses, and Discharge

An assignment transfers rights, not duties. The assignor remains liable for any unperformed duties under the contract unless the obligor agrees to a novation, which is a three-way agreement that substitutes the assignee for the assignor, releasing the assignor entirely.

Upon learning of the assignment, the obligor's primary duty is to render performance to the assignee, not the original assignor. If the obligor mistakenly performs for the assignor after notification, they may have to perform again for the assignee.

A vital protection for the obligor is the defense preservation rule. The assignee stands in the assignor's shoes and takes the assigned right "subject to the defenses" the obligor could have raised against the assignor. If the obligor could have sued the assignor for breach of contract, or if the original contract was voidable for fraud, the obligor can raise those same defenses against the assignee's demand for performance. This principle prevents the assignor from transferring a better right than they themselves possessed.

Successive Assignments and the Importance of Notification

A complex but important scenario arises when an assignor wrongfully assigns the same right to multiple parties (successive assignments). For example, Assignor A assigns a right to payment to Assignee 1, and then later assigns the same right to Assignee 2. Who wins? Jurisdictions follow different rules, but the two most common are the American Rule (first in time) and the English Rule (first to notify).

Under the "first in time" rule, the first assignee (Assignee 1) prevails, provided their assignment was irrevocable. Under the "first to notify" rule, the assignee who first gives notice to the obligor prevails, as this allows the obligor to know with certainty to whom performance is owed. This highlights the paramount importance of the assignee providing prompt, formal notification to the obligor. Notification isn't required to make the assignment, but it is required to perfect the assignee's claim against the obligor and later assignees.

Common Pitfalls

1. Assuming All Rights Are Assignable: The most frequent error is assuming any contractual right can be sold or transferred. Failing to analyze whether an assignment would materially change the obligor's burden can lead to an ineffective assignment and a breach of contract claim.
2. Misunderstanding Anti-Assignment Clauses: Treating a contractual prohibition as an absolute bar is a mistake. You must analyze whether the clause merely creates liability for breach or actually invalidates the transfer. Conversely, ignoring such a clause entirely exposes the assignor to liability.
3. Neglecting to Notify the Obligor: An assignee who fails to notify the obligor takes a serious risk. They leave the obligor free to discharge their debt by paying the assignor, and in many jurisdictions, they risk losing the right to a subsequent assignee who notifies first.
4. Confusing Assignment with Delegation: Professionals often use "assign" colloquially to mean transferring duties. In law, assignment is for rights; delegation is for duties. Attempting to "assign" duties without the obligor's consent is generally a breach, as the obligor has a vested interest in who performs.

Summary

• An assignment is the immediate transfer of an existing contractual right from an assignor to an assignee, who then enforces that right directly against the obligor.
• Rights are not assignable if the assignment would materially change the obligor's duty, increase their burden, or impair their chance of receiving the return performance from the original party.
• An anti-assignment clause typically makes an assignment a breach of contract but does not automatically invalidate it, unless the clause explicitly states that attempts to assign are "void."
• The assignee takes the assigned right subject to all defenses the obligor had against the assignor, and the obligor must perform for the assignee after receiving notification.
• In cases of successive assignments, priority between assignees is often determined by who first notified the obligor, making prompt notification a critical step.
• A present assignment of a right is legally distinct from a mere promise to assign a right in the future; only the former gives the assignee an immediate, enforceable interest.
