What Is Novation in Construction?
Novation is the legal process of transferring an existing contract from one party to another, with the agreement of everyone involved, so the incoming party takes on exactly the same rights and obligations the original party had — as if it had signed the contract from the very start. In construction, novation is most commonly seen when a client’s design consultants, originally engaged directly by the client, are novated to the builder partway through a design and construct project.
Key takeaways
- Novation transfers a whole contract — rights and obligations both — from one party to a new party, replacing the original party entirely.
- It requires the consent of all three parties involved: the party leaving, the party taking over, and the party staying (usually the consultant, the builder, and the client).
- The most common construction use is novating design consultants from the client to the builder on a design and construct (D&C) contract.
- Novation is different from assignment, which only transfers the benefit of a contract, not the underlying obligations.
- A novation agreement should clearly deal with work already done, fees already paid, and liability for anything designed before the novation date.
What is novation?
Novation is a legal mechanism for swapping out one party to a contract for another, with the new party stepping fully into the original party’s shoes — taking on the same rights to be paid and the same obligations to perform, going forward. Unlike simply ending one contract and starting a new one, novation preserves continuity: the underlying scope, terms and history of the original agreement carry across to the new arrangement.
Because novation effectively substitutes one contracting party for another, Australian law requires the consent of everyone affected — the outgoing party, the incoming party, and the party that remains in the contract throughout. This is usually documented in a short novation deed or agreement that identifies the original contract, confirms the incoming party accepts its terms, and releases the outgoing party from obligations arising after the novation date.
Novation turns up in several contexts — corporate restructures, business sales, and finance arrangements — but in construction it is overwhelmingly associated with one specific scenario: a client transferring its design consultants across to the builder partway through a design and construct project.
In plain terms
Novation is like handing the baton in a relay — the same race, the same rules, but a new runner takes over from exactly where the last one left off, and everyone involved has agreed to the swap.
How novation works in design and construct contracts
On a design and construct project, a client will often engage an architect and other design consultants directly, run the design to a reasonably advanced stage — sometimes as far as a development application or even a detailed design — and then novate those consultants across to the builder once the D&C contract is signed.
From that point on, the consultants continue the design under instruction from the builder rather than the client, and the builder becomes responsible for completing and delivering the design as part of its overall design and construct obligation. The client is left with a single point of contractual responsibility — the builder — for both the design and the construction, which is one of the main commercial reasons clients choose a D&C delivery method in the first place.
- The client engages design consultants directly and progresses the design to an agreed stage
- The client and builder sign the D&C head contract, which includes an obligation to novate the consultants
- A novation deed is signed by the client, the builder and each consultant, transferring the consultant agreements to the builder
- The consultants continue working, now taking instructions from — and being paid by — the builder
- The builder takes on responsibility for completing the design and delivering the finished works
Novation vs assignment
Novation and assignment are often confused, but they achieve different things and carry very different consequences for the outgoing party.
- Novation — transfers the entire contract, both rights and obligations. The original party is released and the new party is fully substituted in, with the consent of everyone involved.
- Assignment — transfers only the benefit of a contract (typically the right to receive payment or performance), while the assignor usually remains liable for its own obligations unless the contract says otherwise.
- Practical effect — after a full novation, the outgoing party has no further liability under the contract for anything after the novation date; after an assignment, the assignor can still be on the hook for its own performance obligations.
| Feature | Novation | Assignment |
|---|---|---|
| What transfers | Rights and obligations | Rights only (usually) |
| Consent needed | All parties | Often just notice to the other party |
| Outgoing party liability | Released going forward | Can remain liable |
| Typical construction use | Design consultants on D&C projects | Selling the benefit of a receivable or claim |
What a novation agreement should cover
A well-drafted novation deed does more than simply say the contract is transferred — it needs to deal cleanly with the point in time the swap happens, because design work and fees don’t stop mid-project just because the paperwork changes hands.
- The novation date, and a clear split between obligations before and after that date
- Confirmation that fees or work already invoiced to the client have been settled before novation
- Whether the incoming party (the builder) accepts liability for design work done before the novation date
- Continuity of the consultant’s professional indemnity insurance across the novation
- Any amendments to the original consultant agreement that apply from the novation date onward
Why clients and builders use novation
From a client’s perspective, novating the design consultants to the builder consolidates responsibility. Rather than juggling a separate contract with the architect and a separate contract with the builder — and the finger-pointing that can follow when something goes wrong at the design-construction interface — the client has one party, the builder, responsible for the whole outcome.
From a builder’s perspective, taking over consultants who already know the project avoids the cost and delay of starting the design again from scratch, and lets the builder complete the documentation with a team already familiar with the client’s brief and the site. It does mean the builder inherits some risk for design decisions made before it was involved, which is exactly why the novation deed’s treatment of pre-novation liability matters so much.
Who manages the novation process?
Novation is typically managed by the parties’ lawyers as part of finalising the D&C head contract, since the novation deed is a formal legal document that needs to align precisely with the head contract terms. The client’s project manager or the builder’s contracts administrator usually coordinates the practical handover — confirming outstanding fees, collecting the design documentation produced to date, and briefing the consultants on the new reporting line to the builder.
Common mistakes with novation
Novation disputes tend to arise from gaps left in the deed rather than from the concept itself being misunderstood:
- Not clearly dealing with fees or design work completed before the novation date, leading to disputes over what the builder actually inherited
- Assuming novation happens automatically on signing the D&C contract, when it actually needs a separate deed signed by all three parties
- Failing to confirm the consultant’s professional indemnity insurance continues to respond to work done both before and after novation
- Treating novation and assignment as interchangeable terms in contract drafting, which can leave liability sitting with the wrong party
How My Trade Hub helps on design and construct projects
Whether or not consultants have been novated, a builder taking over a design and construct project still needs to turn the design documentation into an accurate, priced Bill of Quantities. My Trade Hub’s estimation engine measures the latest drawings and builds a structured, editable takeoff, giving a builder a fast, reliable pricing basis as the design is finished off after novation.
Because the measured takeoff is automated rather than done by hand, a builder can re-price a novated design or respond to design changes 60-75% faster than manual estimation, keeping the tender or contract sum current as the documentation evolves.
Frequently asked questions
What does novation mean in construction?
Novation is the transfer of an entire existing contract from one party to another, with the consent of all parties involved. In construction, it most commonly refers to a client transferring its design consultants across to the builder on a design and construct project.
What is the difference between novation and assignment?
Novation transfers both the rights and obligations of a contract, fully releasing the outgoing party. Assignment usually transfers only the benefit — such as the right to payment — while the assignor can remain liable for its own performance obligations.
Do all parties need to agree to a novation?
Yes. Novation requires the consent of the outgoing party, the incoming party, and the party that remains in the contract throughout, because it substitutes one contracting party for another entirely.
Why are consultants novated on design and construct contracts?
Novating design consultants from the client to the builder gives the client a single point of responsibility for both design and construction, and lets the builder complete the design with a team already familiar with the project rather than starting again.
Is the client still liable to the consultant after novation?
No, not for obligations arising after the novation date. A properly drafted novation deed releases the outgoing party — usually the client — from ongoing obligations, with the incoming party, usually the builder, taking those on instead.
What happens to design work done before the novation date?
This should be dealt with explicitly in the novation deed. Typically, fees and work completed before the novation date are settled between the client and the consultant beforehand, with the builder taking responsibility only from the novation date onward — though the deed may allocate some pre-novation design liability to the builder as well.
