Key Takeaways

  • A legal assignment is the transfer of property rights or contractual benefits from one party (assignor) to another (assignee), subject to certain legal requirements.
  • Assignments must involve legally valid subject matter, consideration, mutual consent, and parties with legal capacity to contract.
  • Certain rights, such as personal injury claims or future wages in some states, generally cannot be assigned.
  • Assignments differ from delegations (transfer of duties) and novations (creation of a new contract replacing the original one).
  • Effective assignments should include written documentation, clear language about the rights transferred, and notice to relevant parties.
  • Businesses often use assignments for mortgages, intellectual property rights, accounts receivable, and other contractual benefits.
  • Poorly drafted assignments or those that significantly alter contractual obligations may be unenforceable.

The legal definition of assignment is when a person transfers a piece of property or contractual rights to another person.

What is Assignment?

If you own a piece of property or have rights in a contract and would like to transfer either of these items to another person, you can make an assignment. For instance, if you own a trademark, you could transfer rights to your mark to someone else interested in using the mark.

Before an assignment will be legal, several requirements must be met:

  • All parties must be legally capable.
  • The objects being transferred must be legal.
  • Consideration should be included.
  • All parties must consent to the assignment.

One of the most common forms of assignment is a wage assignment. For instance, if you owe child support, alimony, back taxes, or some other form of debt, the court can require your employer to withhold a portion of your paycheck.

It is also possible to make an assignment for a mortgage. With a mortgage deed, you can give property interest to a lender in exchange for regular payments. Lenders frequently sell mortgages to other lenders. To complete the sale, a mortgage assignment document would need to be used. This document can clarify how payments will be made and can also be used to alter the terms of the mortgage.

Several factors can influence how assignment plays out. In particular, the language of the contract involved in the assignment can impact this process. Certain contracts, for instance, contain clauses that completely eliminate the possibility of assignment. In other contracts, assignment can only occur if the party being assigned the rights and responsibilities of the contract consents.

In some cases, the person making the assignment will still be liable for the performance of the contract. To make sure the contract is completed, a contract can include a provision that requires the original party to make sure the obligations of the contract are fulfilled, even if they have assigned their rights to a third party.

If the assignment significantly changes the terms of the contract, the agreement will usually not be enforceable. For instance, if assignment reduces the contract's value or exposes the other party to more risk, this would be a significant alteration, meaning the courts would not enforce the contract.

It's also possible that an assignment of contract would be restricted by the law. For instance, some states do not allow an employee's future wages to be assigned. Similarly, claims against the federal government usually cannot be assigned. Because it can increase the possibility of litigation, you are not allowed to assign a personal injury claim.

Legal Requirements and Best Practices for Assignments

For a legal assignment to be valid and enforceable, it must meet certain statutory and common-law requirements. These include:

  • Capacity and Consent: All parties involved must have the legal capacity to contract and must freely consent to the transfer. Minors, for example, generally cannot assign contractual rights.
  • Identifiable Subject Matter: The rights or property being assigned must be clearly defined and legally recognized. Future interests that are too uncertain may be unenforceable.
  • Consideration: While not always required, providing consideration (something of value in exchange) strengthens the enforceability of the assignment.
  • No Violation of Contract Terms or Law: The assignment must not breach a clause prohibiting assignment or violate public policy. Certain rights, like personal injury claims or some government-related claims, cannot be assigned.

It’s also considered a best practice to formalize the assignment in writing — especially for high-value contracts — even when oral assignments might be legally valid. A written agreement helps avoid disputes by clearly stating:

  • The identity of the assignor and assignee.
  • A description of the rights or property being transferred.
  • The effective date of the transfer.
  • Any conditions or obligations attached to the assignment.
  • Signatures of the parties involved.

Additionally, notifying the third party (often called the obligor) is crucial. Although not always legally required, notice ensures that future payments or performance are properly directed to the assignee and minimizes the risk of conflicting obligations.

Delegation or Assignment?

In many cases, a person may want to find someone else to fulfill their contractual duties without having to assign the contract. In these cases, you would use a delegation instead of an assignment. Understand, however, that not all contractual obligations are eligible for delegation.

Personal services, for example, usually cannot be delegated. This is because these services are very specific. For instance, if you hired a musical act to play a party, the musician could not delegate their performance to another artist because they were hired with their specific style in mind. If one party wishes to eliminate the possibility of delegation, they should make sure the contract includes language restricting the practice.

Practical Applications of Legal Assignment in Business

Legal assignments play a critical role across a range of commercial and personal contexts. They allow rights and benefits to be transferred efficiently without rewriting entire contracts. Common scenarios include:

  • Mortgage and Loan Transfers: Lenders often assign mortgage rights to other financial institutions, transferring the right to collect payments.
  • Intellectual Property (IP): Creators or companies may assign copyrights, trademarks, or patents to another party, often as part of a sale or merger.
  • Accounts Receivable: Businesses can assign the right to collect payments on invoices to a factoring company in exchange for immediate cash flow.
  • Insurance Claims: Policyholders may assign the right to receive insurance proceeds to third parties, such as medical providers, to settle debts directly.
  • Employment and Wage Assignments: Although limited by law in many states, some contracts involve assigning wages or benefits, often for debt repayment or legal obligations.

In all these cases, the underlying principle remains the same: the assignor gives up their right to receive benefits, and the assignee steps into their place. However, unless expressly stated otherwise, the assignor might still bear secondary liability if the assignee fails to perform under the original contract.

Novation and Assignment

In regard to assignment, it's important to understand that only contractual benefits can be assigned. It is not possible to assign the burden of a contract. For example, if a contractor is hired for a construction project, they could assign their payment but not their obligation to complete the project.

Once an assignment has taken place, the assignee will be able to receive the contract's benefits. The assignee also has the ability to file a lawsuit to enforce their new contractual rights. If there are parts of the contract that still need to be completed, the assignor would be responsible for making sure that this occurs. If the contract is not fulfilled, the assignor would be legally liable since they cannot assign the burden.

Typically, when an assignment takes place, performance of the contract will be taken over from the assignee, and the assignor will request an indemnification for breach of contract.

Limits, Risks, and Enforceability Issues

While legal assignment is a powerful tool, it comes with several limitations and risks that parties must understand before proceeding:

  • Non-Assignable Rights: Certain rights, particularly those tied to personal skill, trust, or discretion (such as employment contracts or attorney-client agreements), cannot be assigned.
  • Anti-Assignment Clauses: Many contracts include provisions restricting or prohibiting assignment without consent. Violating such clauses can void the assignment or trigger legal penalties.
  • Material Alteration Risks: If the assignment fundamentally changes the nature of the contractual relationship or imposes additional risks on the obligor, courts may deem it invalid.
  • Continuing Liability: Even after assignment, the original party may remain liable if the assignee fails to fulfill obligations, unless a novation replaces the original contract.

From a risk management perspective, both parties should conduct due diligence before executing an assignment. This includes reviewing the original contract for assignment clauses, ensuring the assignee has the capacity and resources to perform, and documenting the transfer clearly. Engaging legal counsel is often advisable, particularly in complex commercial transactions or cross-border assignments.

Frequently Asked Questions

  1. What is a legal assignment in contract law?
    A legal assignment is the transfer of contractual rights or property from one party (assignor) to another (assignee), allowing the assignee to receive benefits under the original agreement.
  2. Do assignments need to be in writing?
    While oral assignments can be valid, written agreements are strongly recommended to avoid disputes and clearly define the scope and terms of the transfer.
  3. Can contractual duties be assigned?
    No. Only rights or benefits can be assigned. Duties typically require a delegation or novation, and some cannot be transferred at all if they involve personal skill or trust.
  4. What happens if a contract prohibits assignment?
    If a contract contains an anti-assignment clause, the assignment may be void or unenforceable without the other party’s consent.
  5. Is the assignor still liable after assignment?
    Usually, yes. Unless a novation occurs, the assignor remains liable if the assignee fails to perform under the contract.
