Can You Be Bound by a Contract You Never Signed?
The short answer: maybe…
Long answer: it depends…
A lot of people assume a contract only becomes “real” once someone has scrawled their signature at the bottom, magically flipping the deal from ‘just chatting’ to ‘legally binding’. But that’s not how Australian contract law works.
The Contract Recipe
A binding contract needs four ingredients: an offer, acceptance, consideration (exchanging value) and an intention to be legally bound. What’s not included? Ink.
A signature is one way of showing the parties meant to be bound and it’s a very convincing indication, which is why it remains best practice. But it’s not the only way. Courts look at the full picture: the language used, the conduct of the parties, the surrounding circumstances. A signature can be compelling evidence of intention, but it is not a substitute for it. That cuts both ways. An unsigned agreement can still be enforceable if everything else points to the parties having struck a deal. And a signed document won’t necessarily lock things in if other conditions remain outstanding or the terms themselves are uncertain. But it’s not the only way and its absence doesn’t automatically mean there’s no deal. Equally, its presence doesn’t mean the deal is locked in either.
The case Australian lawyers reach for in this instance is Masters v Cameron. Here, the High Court was dealing with a familiar scenario: the parties had agreed on terms, but there was also talk of a more formal document to follow. The question was whether the deal was already done, or whether everyone was just warming up for the “real” contract.
When Signatures Matter, and Don’t Matter
The Court sorted these situations into three categories, which illustrate common contractual scenarios:
- “We’re bound now, and the formal document is just a record of it.”
Here, the parties have already struck their deal. The formal contract which will be signed later is just meant to tidy things up on paper. It is a formality, not a precondition. The result is that the agreement is enforceable straight away, signed document or not.
If the conduct of both parties aligns with the terms of the deal even having not signed anything yet, that contract will be enforced because of the intention evinced on both ends.
- “We’re bound now, but we won’t actually do anything until the formal document is signed.”
The terms of the deal have been finalised and is enforceable but performance (paying money, handing over goods etc.) is conditional on the formal document being executed. There’s a binding contract, and the parties are required to execute the formal document to give effect to the deal.
- “We don’t intend to be bound at all until the formal document is signed.”
In an instance such as this, the parties have only agreed in principle. Until that formal document is signed, there’s no contract and either side can walk away, no matter how detailed the email chain or how many times someone has said “deal”.
The difference between these categories comes down to the parties’ intention, worked out from the surrounding facts, the language used, the conduct of the parties and so on.
Does an Email Signature Count?
Then what of a typed name at the bottom of an email?
The good news (or bad news, depending on which side of the deal you’re on) is that a signature doesn’t have to be handwritten to do the job. An electronic signature counts provided all parties agreed to the electronic signing, the method used identifies the signatory and their intention in respect of the document and is as reliable as appropriate in the circumstances.
Just like a handwritten signature, it comes back to the full picture. An electronic signature might signal agreement to be bound, or it might just be how the sender ends every email. Automatically generated signature blocks tend to carry less weight for this reason – they’re present regardless of intention.
Take a contract formed purely through email with no attachments. An automatically generated signature block won’t do the heavy lifting here; it tells you very little about intention. An e-signature needs to evidence an intention to approve what’s being communicated, not just sign off on a Monday afternoon. That said, if the email containing the auto-signature also carried a clear statement of acceptance, the picture shifts. It’s all about context.
Why This Matters for Your Business
If you’ve ever:
- Sent a letter of intent or heads of agreement and assumed it was non-binding by default;
- Started performing under a deal while “the lawyers finalise the paperwork”; or
- Assumed an unsigned draft contract sitting in your inbox carries no legal weight
…then this is directly relevant to you. Depending on how things were worded and how everyone behaved you could already be bound, or you could be free to walk away.
In short: Signatures matter, but they’re not everything. They’re strong evidence of intention, and for some types of contracts (property transactions) they’re a legal requirement, not just good practice. But for many commercial agreements, the absence of a signature doesn’t automatically save you from being bound.
Quick Tips:
- If you’re opting for a ‘digital signature’ route, it’s worth clarifying with the other party what that looks like. A Docusign link lands very differently to a typed name at the bottom of an email.
- Already acting like the deal is done? Make sure your paper/digital trail reflects that. Make it clear to the other side “we consider this binding and the formal document is a formality”.
- If you’re not ready to commit, pop in a “subject to contract” as early and as consistently as you can.
