Deed of Assignment or Deed of Novation: Key Differences and Legal Implications of Novation and Assignment Contracts

Key Takeaways

  • Novation transfers both rights and obligations: It requires consent from all original and new parties, effectively creating a new contract and terminating the original one.
  • Assignment transfers only benefits, not burdens: The original contract remains intact, and the assignee steps into the assignor’s position for rights but not obligations.
  • Consent is critical for novation: Unlike assignment, novation cannot proceed without unanimous agreement, making it a more complex but thorough solution.
  • Choose based on objectives: Use novation for a clean transfer of all duties or assignment for simpler rights transfer, depending on the contractual needs and consent availability.

Introduction

In contract law, novation and assignment are pivotal processes for transferring contractual rights and obligations. These legal concepts allow parties to a contract to adapt to changing circumstances, ensuring that business arrangements remain relevant and effective.

This article explores the nuances of novation and assignment, shedding light on their distinct legal implications, procedures, and practical applications. Whether you are a business owner, an individual in a contractual relationship, or a stakeholder in a construction contract, this guide provides the essential knowledge to navigate these complex legal processes.

What is a Deed of Novation?

Novation is a legal process in contract law where a new party replaces an original party, transferring both the responsibilities and benefits of the contract to a third party. Under common law, this transfer of contractual obligations requires the consent of all original parties and the new party joining the agreement. This is because a novation effectively terminates the original contract and creates an entirely new one.

Many agreements contain a novation clause that explicitly requires written consent from the current parties before a novation can occur. This provision helps prevent claims of novation arising from verbal agreements or the conduct of the parties.

However, courts will ultimately assess the specific events that took place, meaning a novation clause is not always strictly enforceable. It is also possible for a contract to permit a future novation by one party to a party of their choosing, which courts will uphold if the original contract’s terms are interpreted to allow it.

In business and contract law, novation is a common tool for transferring contractual rights and duties, particularly when:

  • An original party cannot fulfil its obligations
  • An original party wishes to exit the agreement

What Makes a Deed of Novation Valid?

For a novation to be valid, several conditions must be met:

  • There must be unanimous consent from all parties—the original party, the new party, and the remaining party—to substitute the new party
  • A three-way agreement must be established to formalise this substitution
  • The novation agreement must be documented in writing and signed by all involved parties

Understanding the principles of novation is crucial, as it provides a formal mechanism for parties to delegate their contractual responsibilities and release themselves from the original agreement.

What is a Deed of Assignment?

A deed of assignment is a legal document that transfers a specific right or benefit from one party (the assignor) to another (the assignee). By executing this deed, the assignee effectively steps into the assignor’s position with respect to the benefits under the original contract.

For example, in a construction project, a main contractor might assign its rights under a subcontract directly to the employer. Consequently, if the main contractor fails to enforce the subcontractor’s duties, the employer can pursue those duties directly.

Key aspects that define an assignment in contract law, and distinguish it from a novation, include:

  • Continuation of the Original Contract: The initial agreement remains valid and enforceable even after rights or benefits are transferred. Unlike a novation, an assignment does not create a new contract.
  • Assumption of Rights and Obligations: The assignee adopts the assignor’s rights and responsibilities as outlined in the original contract.
  • Requirement for Written Form: To be valid, an assignment must be documented in writing, signed by the assignor, and formally communicated to the obligor (the party required to perform under the contract).
  • Subject to Terms and Law: The ability to assign rights or benefits depends on the specific terms of the contract and relevant legal statutes.

Under common law, parties generally may assign their contractual rights without obtaining the other party’s consent. However, this default rule does not apply if:

  • the rights are personal in nature, or
  • the contract contains an assignment clause that restricts or modifies the general right to assign.

Many agreements include such provisions to ensure that no transfer occurs without the other party’s knowledge and approval.

Once an assignment is effected, the assignee gains the right to benefit from the contract and can initiate legal proceedings to enforce those rights. It is important to note, however, that while contractual rights can be assigned, the corresponding obligations or burdens cannot be transferred in this way. Consequently, the assignor remains liable for any unfulfilled obligations at the time of the assignment, a situation that often requires resolving construction disputes.

Key Differences Between Novation and Assignment Deeds

AspectNovationAssignment
Transfer of rights or obligationsTransfers both the benefit and the burden of a contract to a third party.Transfers only the benefit of a contract, not the burden.
Consent RequiredNovation requires the consent of all parties (original parties and incoming party).It can typically be simpler; it may not require a formal agreement, depending on the original contract’s terms.
Nature of ContractCreates a new contractual relationship; effectively, a new contract is entered into with another party.Maintains the original contract, altering only the party to whom benefits flow.
FormalitiesTypically effected through a tripartite agreement due to the need for all parties’ consent.It can often be simpler; it may not require a formal agreement, depending on the original contract’s terms.

Choosing Between Assignment and Novation in a Construction Contract: Key Factors to Consider

In building and construction law, choosing between an assignment and a novation in a construction project, especially in a scenario where an employer loses confidence in the main contractor and wishes to engage a subcontractor directly, depends on several key factors.

The decision hinges on the following considerations:

  • Nature of the Contract: The type of agreement, such as a service or sales contract, can determine the best approach. Novation is often preferred for service contracts where the obligations are personal and specific to the original parties, as it ensures a complete transfer of responsibilities.
  • Parties Involved: Consent is a critical distinction. A novation requires the unanimous agreement of all original parties and the new party, making it suitable only when all stakeholders are willing to agree. An assignment may be more practical if obtaining universal consent is difficult.
  • Complexity of the Transaction: For straightforward transfers of benefits, an assignment is often sufficient. However, for more complex transactions involving multiple rights and duties, a novation provides a cleaner break by transferring all aspects of the contract, which prevents the original party from having lingering responsibilities.
  • Time and Cost: Practical considerations like time and expense are important. A novation generally involves a more intricate legal process due to the need for a tripartite agreement, and can be more time-consuming and costly than a simple assignment.

If the goal is simply to transfer the rights to a subcontractor’s work to the employer without changing the subcontractor’s duties, an assignment will likely be adequate. However, if the objective is to completely transfer the main contractor’s role and all associated obligations to the employer or another party, a novation is necessary. This ensures all parties consent to the new arrangement and formally releases the original contractor from their duties.

Ultimately, legal interpretations and court decisions emphasise the substance of a document over its title. A document labelled a “Deed of Assignment” may function as a novation if it transfers both obligations and rights with the consent of all parties. The primary goal is to clearly define the intended change in the contractual relationship and use the deed that best achieves the desired legal and practical outcomes for the project’s successful completion. This ensures the continuity and successful completion of the construction project.

Selecting the Right Assignment Clause for Your Contract: Helping You Make the Right Choice

Understanding the distinction between novation and assignment deeds is crucial in contract law. Each method serves a different strategic purpose:

  • Novation creates a clean slate by transferring both rights and obligations to a new party with the consent of all involved.
  • Assignment allows for the transfer of contractual benefits without altering the original party’s obligations.

The choice between novation and assignment hinges on the specific legal and practical considerations unique to your situation.
