Deed of Assignment vs Novation: The Difference (2026)

When one party wants to hand a contract, or its benefit, to someone else, there are two main legal routes: assignment and novation. They sound technical and they are often confused, but the difference is practical and important. Assignment transfers the benefit of a contract. Novation transfers the whole contract, benefit and burden, and needs everyone's agreement. Choosing the wrong one can leave you still liable for obligations you thought you had passed on. This is general information, not legal advice. The rules on assignment and novation vary by jurisdiction, so confirm your local position before relying on either. ## First, benefit versus burden Every contract has two sides for each party: the benefit (the rights, such as the right to be paid or to receive a service) and the burden (the obligations, such as the duty to pay or to deliver). This distinction is the key to the whole topic. The general rule is that you can transfer the benefit of a contract fairly freely, but you cannot transfer the burden to someone else without the agreement of the party you owe it to. That single rule is why assignment and novation exist as separate tools. ## Assignment: transferring the benefit Assignment moves the benefit of a contract from the assignor to the assignee. For example, a supplier owed money under a contract can assign the right to receive that money to a third party, perhaps a finance company. The customer now pays the assignee instead. Key features of assignment: - It transfers rights only, not obligations. The original party usually stays responsible for its own obligations.

• It generally does not need the other contracting party's consent, unless the contract says it does. Many contracts contain a clause restricting or prohibiting assignment, so always check.
• It is often recorded in a deed of assignment, especially for valuable rights or where no fresh consideration is being given, because a deed does not require consideration to be binding.
• Notice should usually be given to the other party so they know to perform for the assignee (this is a "legal" assignment in many systems; without notice it may be only an "equitable" one). ## Novation: transferring the whole contract Novation replaces the original contract with a new one in which an incoming party takes the place of an outgoing party, assuming both the benefit and the burden. The classic case is selling a business: the buyer novates the supply and customer contracts so that it steps fully into the seller's shoes. Key features of novation: - It transfers rights and obligations together.
• It needs the agreement of all three parties: the outgoing party, the incoming party, and the party remaining on the other side. Without the remaining party's consent, you cannot novate.
• It is documented in a novation agreement (often a deed), signed by all three.
• The outgoing party is released from future obligations once novation completes, which is exactly why the remaining party's consent is required; they are agreeing to look to a new counterparty. ## The practical difference in one line Use assignment when you only need to pass on the benefit and the other side's consent is not needed (or the contract allows it). Use novation when the incoming party must take over the obligations too, and everyone agrees to release the outgoing party. If you try to "assign" your obligations, it will not work; you stay liable. That is the mistake that catches people out. ## Why a deed is often used Both transfers are frequently done by deed rather than a simple signed agreement. A deed is binding even without consideration (something of value passing), which matters when, for example, a right is being gifted or transferred within a group for no payment. A deed also typically carries a longer limitation period in some jurisdictions. The formalities for a valid deed, such as being signed, witnessed, and stated to be a deed, are strict and local, so follow them exactly. ## Common mistakes to avoid - Trying to assign obligations, which does not transfer them; you remain liable, and novation was needed.
• Ignoring an anti-assignment clause in the original contract.
• Forgetting to give notice of an assignment, so it is not fully effective against the other party.
• Attempting novation without the remaining party's consent.
• Using a simple agreement where the formalities of a deed were required.
• Assuming the outgoing party is released on an assignment; only novation releases them from the burden. ## Keeping track of who is now party to each contract After a few assignments and novations, especially following a sale or reorganisation, it can be genuinely unclear who is now party to a contract, who carries the obligations, and whether the right consents and notices were ever obtained. That uncertainty is a real risk when a dispute or an audit arrives. Keeping each contract, its assignments, and its novations connected in one place, with the consents recorded, keeps the chain of title clear.

The guidance above works on its own. ## Bottom line Assignment transfers the benefit of a contract and usually does not need the other side's consent, though an anti-assignment clause can block it; it leaves obligations with the original party. Novation transfers the whole contract, benefit and burden, releases the outgoing party, and requires every party's agreement. Both are often done by deed because a deed binds without consideration. Pick novation whenever obligations must move, and check consents and notices carefully. Because the rules are local and the formalities strict, confirm your document with a qualified lawyer before relying on it.
