Novation vs Assignment: How To Transfer A Contract In New Zealand

If you’re running a small business, there’s a good chance you’ll eventually need to “transfer” a contract.

Maybe you’re selling the business, restructuring your group, bringing in a new entity, or handing a project to another supplier. On paper, it can look as simple as telling everyone “Company B is taking over now”. In practice, the legal mechanism you choose matters a lot.

The two most common options are novation and assignment. People often ask about novation vs assignment because the concepts sound similar - but they don’t do the same thing, and picking the wrong one can leave you with unpleasant surprises (like still being on the hook for performance or payment).

Below, we break down how novation and assignment work in New Zealand, when to use each, and what to watch for so you’re protected from day one.

What’s The Difference Between Novation And Assignment?

The simplest way to think about it is:

• Assignment generally transfers rights/benefits under a contract (for example, the right to receive payment). It doesn’t automatically transfer obligations (like the obligation to deliver the service), and any attempted transfer of obligations usually needs the other party’s agreement (and the contract must allow it).
• Novation replaces a party to the contract, so that a new party steps into the contract and the old party is typically released from future obligations (depending on how it’s drafted).

If you want a handy “gut check”:

• If you’re trying to transfer only what you receive under the contract (like payments), assignment might fit.
• If you’re trying to transfer the whole role (rights and obligations), novation is usually the safer route.

In both cases, the exact wording of the contract you’re transferring (and any proposed transfer document) is crucial. One badly drafted clause can undo the whole point of the transfer.

A Quick Example

Let’s say your business has a 12-month services contract with a client.

• If you assign the contract, you might be able to assign the right to invoice and collect fees - but you may still be responsible for delivering the services unless the client agrees to a change of provider (and the documents are structured correctly).
• If you novate the contract, the new provider replaces you and becomes responsible for delivering the services, and the client pays the new provider.

When Should A Small Business Use Assignment?

Assignment can be useful when you only need to transfer the benefit of a contract - not the whole relationship.

In New Zealand, assignment is often used for things like:

• Debt and receivables: assigning the right to receive money owed (for example, you’re selling your invoices/receivables to another entity).
• Payment rights under a commercial arrangement (subject to the contract’s restrictions).
• Insurance proceeds or similar contractual benefits (again, subject to the contract terms and the nature of the right).

But here’s the important part: assignment is not a “magic wand” that lets you hand over everything.

What Can (And Can’t) Be Assigned?

While assignment is a well-recognised concept, there are practical limits:

• Rights are generally easier to assign than obligations. A party can often assign the benefit of receiving something, but shifting the burden of performing services is usually not possible by assignment alone.
• Personal service contracts (where the client contracted because of your skill/relationship) can be difficult or inappropriate to assign without consent.
• Your contract might ban assignment or require the other party’s written consent before any assignment can happen.

As a business owner, it’s worth reading the “assignment” and “change of control” clauses early - ideally before you’re in the middle of a sale or restructure and up against a deadline.

If you’re transferring a contract in a more formal way, you may need a Deed of Assignment that matches what the underlying contract allows.

Does Assignment Need Consent?

Sometimes yes, sometimes no - it depends on the contract and what exactly is being assigned.

Many commercial contracts in New Zealand include a clause like “A party must not assign without the other party’s prior written consent.” If that’s in your contract and you assign anyway, you may be in breach (and you could trigger termination rights).

Even where the contract is silent, consent issues can still come up in practice, especially where the “benefit” you’re trying to assign is closely linked to performance obligations or the other party’s risk.

When Should A Small Business Use Novation?

If you want to transfer the whole contract - including responsibility for performance - novation is often the right tool.

Novation is common in situations like:

• Selling your business, where the buyer should take over customer/supplier contracts going forward.
• Restructuring (for example, moving a contract from you as a sole trader into a newly formed company, or between group companies).
• Replacing a contractor/supplier on a project while keeping the same overall contract terms in place.
• Transferring agreements tied to operational obligations (like ongoing service delivery).

The core feature is that the original contract is effectively “re-made” with a new party in place of an old party. That’s why consent is a bigger deal here.

Does Novation Require Everyone’s Consent?

In most cases, yes. Because novation replaces a party and changes who is legally responsible, it typically requires the agreement of:

• the outgoing party (you),
• the incoming party (the new entity), and
• the counterparty (the other side of the contract).

This is also why novation is often documented in a formal deed, especially for higher-value or higher-risk arrangements. If you’re documenting the transfer properly, a Deed of Novation is commonly used.

Does Novation Automatically Release The Old Party?

This is where small businesses can get caught out.

Novation can release the old party, but it depends on what the novation document says. If the goal is a clean handover, your novation should clearly deal with:

• whether you’re released from future obligations,
• who is responsible for past breaches or liabilities,
• how disputes are handled during the transition, and
• any practical handover steps (data, access, deliverables, IP, etc.).

Without clear drafting, you can end up in a messy “everyone thought someone else was responsible” situation - which is exactly what you’re trying to avoid by transferring the contract in the first place.

Novation Or Assignment: A Practical Comparison For Business Owners

If you’re weighing up novation or assignment, here’s a practical comparison from a small business perspective.

What Each Option Usually Achieves

• Assignment: Transfers benefits/rights (commonly the right to receive payment). The original party will often remain responsible for performance obligations unless those obligations are separately restructured with the counterparty’s agreement.
• Novation: Transfers the contract relationship to a new party (rights and obligations), usually requiring all parties’ consent.

Who Needs To Agree?

• Assignment: May be possible without the other party’s consent if the contract permits it and you’re only assigning rights (but many contracts require consent anyway).
• Novation: Generally requires agreement from all parties because it changes who the counterparty is dealing with.

Risk And Liability

• Assignment: Can leave you with “hidden liability” if you assume you’ve handed over the contract but you’re still responsible for performance or breaches.
• Novation: Often cleaner for liability going forward (if drafted properly), because responsibility is clearly shifted to the incoming party.

Common Use Cases

• Assignment: Receivables, rights to payment, certain benefits under a contract.
• Novation: Business sales, restructures, replacing the service provider, moving contracts between entities.

If you’re still unsure, a good way to decide is to ask:

• Do I want to stop being responsible for delivering the contract?
• Does the other party need to be comfortable with who they’re dealing with going forward?
• Does the contract contain restrictions on assignment, novation, or change of party?

Those answers usually point strongly toward either assignment or novation.

What Should You Check Before Transferring A Contract?

Before you sign anything (or tell the other side “it’s all sorted”), it’s worth doing a quick legal health check on the contract and the deal structure.

1) Read The Transfer Clauses Carefully

Look for clauses dealing with:

• Assignment (is it allowed, and on what conditions?)
• Novation (sometimes the contract uses “novation” or “substitution” wording)
• Change of control (even if you don’t “transfer” the contract, a sale of shares can trigger consent requirements)
• Termination (what events allow the other party to end the contract?)

If the contract is unclear or high-stakes, getting a Contract Review can save you from committing to a transfer structure that doesn’t actually work.

2) Work Out What You’re Actually Trying To Transfer

Be specific. Are you transferring:

• the right to invoice?
• the obligation to deliver services?
• ownership of work product or IP?
• confidential information and data access?
• existing liabilities (or only future performance)?

This is especially important when the contract is part of a broader transaction like a business sale. Often you’ll be transferring multiple agreements at once, and they won’t all be treated the same way.

3) Check If There Are Other Documents In The Background

Some contracts don’t stand alone. You might have related documents such as:

• an NDA,
• service levels / statements of work,
• personal guarantees,
• security interests, or
• linked agreements with third parties.

A transfer document should usually address how those linked documents are handled - otherwise you can end up transferring only half the arrangement.

4) Don’t Forget About Leases

If you’re transferring a business, the premises arrangement is often critical. Commercial leases are usually transferred by a specific process (and the landlord almost always needs to consent).

If the contract you’re “transferring” is a lease interest, you’ll usually be looking at Assigning a Lease rather than a standard services contract transfer.

5) Make Sure The Old Contract And The New Document Match

This sounds obvious, but it’s a very common problem: the transfer deed says one thing, and the original contract says another.

For example:

• The contract requires consent in a particular form (e.g. “written consent signed by a director”), but you only have an email.
• The contract bans assignment entirely, but you attempted an assignment anyway.
• The transfer document doesn’t deal with “effective date”, so everyone is confused about who was responsible during the transition period.

These are the sorts of issues that lead to payment disputes, service gaps, and headaches when something goes wrong.

Common Mistakes When Choosing Novation Or Assignment (And How To Avoid Them)

Even when business owners understand the theory, the practical execution is where problems happen. Here are some common traps we see.

Mistake 1: Assuming Assignment Transfers Obligations

This is probably the biggest one. If you assign a contract but the customer still expects you to perform (and legally, you may still be responsible), you can end up:

• doing work you thought you’d handed over, or
• being blamed for non-performance by the new party.

Where performance is meant to move to the new party, novation is often the cleaner approach.

Mistake 2: Not Getting Consent Properly (Or At All)

Consent issues can derail a transaction late in the process. If the contract requires consent and you don’t obtain it:

• you may be in breach,
• the other party may refuse to pay, and/or
• the other party may have termination rights.

If you’re already in negotiations and the other party is pushing back, you may need to consider whether a clean exit is better handled by Terminating a Contract and entering into a fresh agreement, rather than trying to force a transfer that isn’t permitted.

Mistake 3: Forgetting About Past Liabilities

Even if you transfer the contract relationship going forward, what happens to things that happened before the transfer date?

A well-drafted novation or assignment arrangement should deal with:

• unpaid invoices,
• existing defects or disputes,
• warranties and service credits,
• data security incidents (if relevant), and
• who handles existing claims.

It’s much easier to agree on this when everyone is on good terms and the transaction is progressing - not after a dispute has started.

Mistake 4: Using A Generic Template

Transfer documents are one of those areas where templates can be risky, because the “right” approach depends on:

• the underlying contract’s wording,
• what is being transferred (rights only vs full relationship), and
• the commercial deal you’ve negotiated (price, handover, liability split).

If the transfer is part of a bigger transaction, it’s also worth checking how it fits with your sale documents. For example, if you’re selling a business, the way contracts transfer should align with your broader Asset Sale Agreement.

Key Takeaways

• Assignment is generally used to transfer rights/benefits under a contract (like the right to receive payment), but it won’t necessarily transfer obligations to perform.
• Novation is usually the better option when you want a new party to take over both rights and obligations and for you to step out of the contract going forward.
• If your contract restricts assignment or requires consent, transferring without following the process can put you in breach and may trigger termination or non-payment risks.
• A well-drafted transfer document should clearly address the effective date, what happens to past liabilities, and who is responsible for performance after the handover.
• Leases and other “linked” documents often have their own transfer rules, so it’s important to check the whole deal structure before assuming a simple novation or assignment will cover everything.
• If you’re unsure which option fits your situation, getting advice early (before you sign or announce the transfer) can prevent expensive disputes later.
