Transferring a contract sounds simple, but when you dig a little deeper, you’ll quickly come across two legal terms that can make things feel more complicated: assignment and novation. If you’re a small business owner, startup founder, or just navigating your first business contract, you might be wondering: which option is right for me if I want to transfer a contract-or step out of one altogether?
Don’t worry if these terms are new to you! This guide will break down what novation actually means, what an assignment does, when you might use each, and the practical steps to keep your business protected. Whether you’re selling your business, taking on a new project, or handling client contracts as things grow, getting this right can save you major headaches and risks down the line.
Let’s explore the fundamental differences between novation and assignment, clarify their legal impact, and help you choose the right path for your situation.
What Is Novation?
Let’s start at the top: What exactly is novation?
To define novation, it’s a legal process where an existing contract is terminated and replaced with a new one-usually by swapping one of the original parties for a new party. This means all rights and obligations transfer to the new party. Once you novate a contract, the original party is released from all future liabilities, and the new one steps fully into their shoes.
So, in plain terms: Novation = totally replacing a contracting party, which requires a fresh agreement between all those involved. The most common tool for this is called a novation agreement (or “novatio deed”).
You might want to consider novation, for example, if:
- You’re selling your business and need customers, suppliers, or employees to deal with the new owner from now on (not you).
- You want someone else to take over both the benefits and the burdens of a contract, like delivery or service obligations.
- You no longer want any legal responsibilities linked to the agreement.
Key point: With novation, you get a true fresh start-but only if all parties agree to the swap.
What Is Assignment?
Now, let’s dive into the question: What is an assignment?
An assignment simply transfers your rights (the benefits) under a contract to someone else, but you keep your obligations (the responsibilities). For example, if you’re owed payment under a service contract, you can assign your right to receive that payment to another business-maybe to collect a debt or as part of selling your assets. However, you’d still be on the hook for carrying out any ongoing duties unless otherwise agreed.
A few common scenarios where assignment works:
- Transferring receivables (the right to be paid), such as when you sell invoices to a factoring company.
- Transferring rights in a contract with a supplier, but the supplier continues to deliver goods or services to you as the original contracting party.
- Passing on entitlement to certain benefits (like insurance claims) to a new party without getting rid of your responsibilities under the contract.
Key point: With assignment, only the “good stuff” (your rights) are passed on. You still need to keep your promises under the contract-unless the contract or other parties say otherwise.
What’s the Difference Between Novation and Assignment?
At this stage you might be thinking: both novation and assignment seem to transfer things-what’s the real difference?
Here’s a quick breakdown of how the two compare:
- Assignment: Transfers rights only. Original contracting party keeps their obligations. New party steps in just to receive the benefits.
- Novation: Transfers rights and obligations. The new party replaces the original party in every respect. The original party steps out of the contract for good.
Let’s dig into the details where things really diverge:
1. Transfer of Rights vs Obligations
- Assignment: Only the right to receive something (for example, money or goods) is transferred. You-the assignor-are still responsible for doing whatever the contract requires.
- Novation: Everything-both rights and responsibilities-move over to the new party. The person or business stepping in takes over the contract from top to bottom.
2. Consent Requirements
- Assignment: Generally, you don’t need the other party’s permission (unless your contract specifically says you do), but it’s always best practice to let everyone know. If the contract forbids assignment, trying to assign anyway can lead to legal trouble.
- Novation: Every party needs to say yes-including the one joining the contract and the one stepping out. You’ll all sign a novation agreement to put this in writing.
3. Consideration
- Assignment: No “new” consideration needed-since the contract carries on as-is, just with rights shifting hands.
- Novation: Requires consideration-a clear exchange of value between the parties-just like forming any new contract. This is needed to make the changes legally binding under UK contract law.
4. Impact on Liability
- Assignment: You remain liable for the contract. If things go wrong, your business can still be held responsible.
- Novation: You’re released from liability for everything that happens under the contract after the novation takes effect. The new party assumes all the risks and rewards from that point forward.
5. Documentation
- Assignment: Can be done with a simple written or verbal notice (though in practice, a deed or letter of assignment is best for clarity).
- Novation: Must be recorded through a novation agreement signed by all parties for it to be legally valid and enforceable.
When Should You Use Novation?
There are times when transferring your obligations is just as important as transferring your rights-novations shine in these scenarios. Here are some common examples:
- Selling your business – If you’re exiting your business and need your supplier contracts, customer agreements, or employee contracts to move 100% to the new owner, a novation is the gold standard. The new owner becomes responsible for everything, and you’re released from risk.
- Transferring ongoing projects or supply contracts – If you’re delivering a service on a long-term contract but want someone else to both deliver and get paid for the remainder, only novation can achieve this clean swap.
- Restructuring or merging two businesses – When consolidating contracts under a new entity or moving contracts around within a group of companies, novation makes sure everyone’s on the same page with new roles and obligations.
In short: choose novation if you need to step away entirely from both benefits and duties-and get all sides to agree in writing.
When Is Assignment More Appropriate?
Assignment, on the other hand, is perfect when you want to hand off just the benefits (say, receiving payments or using a certain service) without changing who’s responsible for actually performing the contract.
- Selling receivables or debts – If you’re selling an unpaid invoice or right to payment, assignment gets this done quickly (and often without fuss).
- Passing on contract rights – You're moving just the “good stuff” to a new party-perhaps for restructuring, or as part of asset sales-while you manage the rest.
- Delegating benefits without full substitution – If you want someone else to receive a benefit under contract, but you’re happy to keep living up to your responsibilities.
Remember: with assignment, you can’t force the other party to deal only with the new assignee-they might still come to you if things go wrong, unless the contract or a separate agreement says otherwise. If your goal is a “clean break”, assignment alone won’t cut it.
Legal Steps and Best Practices
Choosing between novation and assignment is an important business decision-getting the details wrong can expose you to risk, disputes, or even financial penalties. Here are a few practical steps to guide you:
- Check your current contracts. Look for any clauses that restrict your right to assign or novate. Many agreements say you need written consent from the other party, or even expressly forbid assignment. Violating these terms could lead to a breach of contract (and legal consequences).
- Get everything in writing. Whether you’re assigning or novating, don’t rely on handshakes or emails alone. Use a clear, professional agreement (assignment deed or novation agreement) to document the terms, date, and parties involved.
- Obtain consent if needed. Novation always needs consent. For assignment, it depends on the contract, so double-check your paperwork before proceeding. Even when not strictly needed, courteous notice is recommended-this keeps relationships positive and reduces friction.
- Address consideration (for novation). Make sure the novation agreement includes details of what value is being exchanged (the “consideration”) to make the contract enforceable under UK law.
- Seek tailored legal advice. Every contract and scenario is unique. Getting a legal expert to review your contracts and draft or review any proposed assignment or novation will help ensure you’re fully protected and avoid costly mistakes.

Potential Pitfalls and Risks
Here’s what can go wrong if you don’t get the process right:
- Breach of contract: Assigning or novating without following contract terms can leave you open to damages or legal action.
- Unexpected liability: If you assign rights but forget about your obligations, you might find yourself liable for something you thought you’d left behind.
- Disputes down the track: Without clear documentation, all sides might have different ideas about who’s responsible for what-a recipe for legal trouble.
- Loss of payment or benefits: If the other party refuses to recognise a poorly documented assignment or novation, you could miss out on money or contractual rights.
That’s why it’s always wise to avoid relying on DIY templates or verbal discussions-bespoke legal documents drafted for your circumstances are the safest option.
Practical Examples: Novation vs Assignment in Action
Sometimes it helps to see how this plays out in the real world. Here are a couple of quick scenarios:
- Example 1: Assignment – Imagine you run a marketing agency and you’re about to receive a large payment from a client. You want to assign your right to receive payment to your factoring provider to free up cash flow. In this case, you need to check if your contract allows it and notify your client. The factoring provider will receive the payment, but you’re still liable if the services aren’t up to standard.
- Example 2: Novation – Now suppose you’re selling the same marketing agency. The buyer wants all of your client contracts to move over to them, with the clients dealing with them directly from now on. You’ll use novation agreements with each client, replacing you with the buyer-they step into your shoes, and you walk away without ongoing obligations.

Key Takeaways
- Assignment transfers only your rights under a contract to someone else-not your obligations. You’ll still be liable for performance unless the contract or a further agreement says otherwise.
- Novation transfers both rights and obligations to a new party, releasing you from further responsibility. It requires the consent of all involved parties.
- You don’t usually need new consideration for an assignment, but you do for a novation-so always document what each party is giving and receiving.
- Always check your contracts for assignment/novation clauses, and get any required consents before making a move.
- Use clear, legally drafted documents-don’t rely on verbal promises or templates you find online.
- Get expert legal advice before transferring contracts, so your business avoids risk, liability, and disputes later on.
