Changing an existing agreement

Variation, Novation or Assignment?

These 3 documents do different jobs. A variation changes the terms between the same parties. A novation replaces 1 party with a new party. An assignment transfers 1 party's rights, but not its obligations, to someone else.

A deed of variation is used when the parties want to keep their agreement but change part of it: the price, the term, the scope, a party's name or a particular clause. The deed records exactly which clauses change, the new wording and the date the change takes effect.

A deed of novation is used when a party is stepping out altogether, for example when a business is sold or a contract moves to a related company. The new party takes on the rights and obligations, and the outgoing party is released. All parties, including the one staying in, must agree.

A deed of assignment transfers the benefit of an agreement, such as the right to receive payment, without transferring the burden. The original party remains liable for its obligations unless the other side agrees to release it. Whether an assignment needs consent depends on the original agreement.

These changes are usually made by deed because a deed does not need fresh consideration to be binding, and in NSW the time to bring a claim on a deed is 12 years rather than 6.

Before you start

What to Have Ready

A deed of this kind is only as good as its connection to the original agreement, so that document comes first.

The original agreement: The signed agreement and any variations, side letters or emails that changed it.

The change: The clauses affected and the new terms, or the details of the incoming party.

The parties: Full names and ACNs of each party, including any guarantor and the new party.

Timing: When the change is to take effect and whether anything before that date needs to be dealt with.

Common Mistakes

Changing terms by email: An email exchange may not meet the agreement's own requirements for a variation, leaving it unclear what was agreed.

Assigning when you meant to novate: An assignment leaves the original party liable. If the aim is to step out completely, a novation is usually needed.

Ignoring the original agreement: Many agreements say how they may be varied and whether consent is needed to assign. Those requirements must be followed.

Not signing as a deed: A deed has execution formalities. If they are not met, the document may not have the effect intended.

Points Worth Knowing

Guarantors

Varying a guaranteed agreement without the guarantor's agreement can release the guarantor. Include them as a party.

Security registrations

If the agreement is secured, a PPSR registration may need to be updated when it is assigned or novated.

Leases are different

Variations and assignments of leases follow their own process and may need registration.

Trust deeds

Varying a trust deed depends on the power of amendment in that deed and raises separate duty questions.

Business sales

On a business sale, key contracts are often novated or assigned as part of completion.

Keep a clean copy

After several variations, a consolidated copy of the agreement avoids confusion later.

We prepare deeds of variation, novation and assignment where the change is agreed. We do not act in disputes about the original agreement.

Deed of Variation FAQs

What is a deed of variation?
A deed of variation is a document the parties to an existing agreement sign to change some of its terms. It identifies the clauses being changed, sets out the new terms and confirms that the rest of the agreement continues unchanged.
What is the difference between novation and assignment?
A novation replaces a party, so the new party takes on both the rights and the obligations and the outgoing party is released. An assignment transfers only the rights, and the original party remains responsible for its obligations.
Why use a deed rather than a letter or email?
A deed is binding without fresh consideration, has a longer limitation period, and makes the change formal and clear. It also avoids arguments about whether an informal exchange met the agreement's own variation clause.
Does the other party have to agree?
For a variation or a novation, yes. For an assignment, it depends on the original agreement. Many agreements require consent before rights can be assigned.
Can a variation be backdated?
The parties can agree that a change applies from an earlier date, but the deed should be dated when it is signed and state the effective date separately. Backdating the signing date itself is not appropriate.
What does a deed of variation cost?
Our fixed fees are published on our pricing page. We confirm the fee in writing before any work starts.
Do you handle lease variations?
Yes, through a separate service, because lease variations often need to be registered. See our lease variations page.
