A Queensland home is now more likely to be sold with a fingertip than a fountain pen. The agent sends a link, the buyer opens it on a phone at work, taps the yellow boxes and the contract goes on to the seller, who may be in another state. Nobody meets and nothing is printed. For a purchase that may be the largest of a person's life, it is fair to ask whether that is really enough.

It is, and the reasons are worth knowing, because they also mark the limits. The law that makes an electronic contract valid sets conditions about identity, intention and consent. Other documents in the same sale follow different rules: the disclosure bundle, deeds, company signatures and the forms that go to the titles registry. This guide sets out what Queensland law accepts, section by section, and where the convenience stops. It describes the general position and is not advice on any particular document.

Electronic Transactions (Queensland) Act 2001, section 14; Proctor reports of March and April 2022 on the permanent document-signing reforms.

Why a land contract needs writing and a signature

Most contracts need no formality at all. An agreement to buy a car can be made by a handshake. Land is the old exception. Section 7 of the Property Law Act 2023 says a contract for the disposition of land is not enforceable by action unless the contract, or some memorandum of it, is in writing and signed by the party against whom it is to be enforced. Section 8 adds that the creation of a legal or equitable interest in land must be in writing and signed by the person creating it.

Two requirements follow, writing and signature, and both were framed in an age of paper. Neither section says that the writing must be ink or that the signature must be handwritten. The question of whether pixels can satisfy them is answered by a different statute.

The Act that lets a screen stand in for paper

The Electronic Transactions (Queensland) Act 2001 was passed to settle exactly that question across the whole of State law. Its starting point is section 8: a transaction is not invalid under a State law merely because it took place wholly or partly by one or more electronic communications.

The Act then deals with the two paper-age requirements in turn. Under section 11, a requirement to give information in writing is met by an electronic communication if the information will be readily accessible for later reference and the person receiving it consents to getting it that way. Section 12 applies the same approach where a law permits, without requiring, something to be in writing. Section 14 deals with signatures, and it is the heart of the matter.

Read together with section 7 of the Property Law Act, these provisions mean a contract for the sale of land that exists only as an electronic file, signed only by electronic means, can satisfy the requirement of writing and signature. Nothing in either Act requires a paper original to exist anywhere.

Three tests for an electronic signature

Section 14 does not define an electronic signature by its appearance. It sets out what the method of signing has to achieve.

The first test is about function. A signature tells the reader who is bound and that they meant to be. A method passes if it does those two things, whether it is a name typed at the foot of an email, an image of a handwritten signature pasted into a file, a finger drawn across a touchscreen or a click on a button in a signing platform.

The second test is proportionate. "As reliable as appropriate" depends on what is being signed. A method adequate for a routine form may be thin support for a contract worth a million dollars. The Act also offers a second route: a method satisfies the test if it is proven in fact to have identified the person and shown their intention. A signature that everyone agrees was made by the right person does not fail because the technology was simple.

The third test brings in the other party, and it deserves its own section.

Consent, and how it is shown

Both the writing rule and the signature rule depend on consent. The person receiving an electronic document, or relying on an electronic signature, must consent to it being done electronically.

The Act's dictionary gives consent a practical meaning. It includes consent that can reasonably be inferred from a person's conduct. A buyer who receives a contract by email, signs it on screen and sends it back has shown consent by doing so. The definition also says consent given subject to conditions does not count unless the conditions are met. A seller who says, in effect, "I will accept an electronic contract only through this platform" has not consented to a photographed signature sent by text message.

This is why signing platforms and agents' forms usually open with a statement that the parties agree to deal electronically. The statement is not strictly required where conduct makes consent obvious, but it removes the argument. It also means no one can be compelled to sign on a screen. A party who wants paper may say so, and the law does not treat a preference for ink as unreasonable.

What the standard contract and the platforms add

The statute supplies the principle. The documents used in practice supply the detail. The standard residential contract published by the Real Estate Institute of Queensland and the Queensland Law Society has been adapted to electronic signing over several editions. A summary of the 2022 changes by law firm Bradley Bray notes that the definition of the contract date was updated that year to accommodate signing through the REIQ's forms platform.

A signing platform does more than collect a squiggle. In general terms, it sends each signer a link tied to an email address or mobile number, records when the document was opened and signed, locks the file against later change and produces a certificate listing those events. None of that is demanded by section 14 in so many words. All of it is evidence for the first two tests: who signed, that they meant to, and that the method was reliable.

The weak point in any electronic method is the question of who was holding the device. A platform can show that a document was signed from a particular email account. It cannot show that the account holder, and not a spouse or an adult child, pressed the button. Where a property is owned by two people, each owner needs to sign for themselves, using their own access, unless one holds a valid power of attorney for the other. Agents and solicitors have their own obligations to confirm who they are dealing with, and those do not fall away because the signature is electronic.

When an electronic contract becomes binding

The Queensland Government's guidance on contracts of sale puts the basic rule simply: a contract becomes binding once both parties have signed it. The buyer signs first to make the offer, and the seller's signature accepts it. Electronic signing changes the speed of that exchange and not its logic.

Timing can matter to the hour, and the Electronic Transactions Act has rules for it. Under section 23, an electronic communication is dispatched when it leaves the sender's system. Under section 24, it is received when it becomes capable of being retrieved by the addressee at an electronic address the addressee has designated. A signed contract sitting in the buyer's nominated inbox has been received, whether or not the buyer has opened it.

That rule interacts with cooling-off. The Government's guidance says a residential contract may be subject to a statutory cooling-off period of five business days, with a penalty of 0.25 per cent of the purchase price if the buyer terminates during it. Because electronic delivery is close to instant, a buyer should assume that time starts to run as soon as the fully signed contract reaches their designated address, and should note the date and time shown on the platform's record.

The same precision applies to an offer that has not yet been accepted. Until the seller signs, there is no contract, and a buyer who has signed electronically is in the same position as one who has signed on paper and handed the document to the agent.

Disclosure documents by email or link

Since 1 August 2025 a Queensland seller has had to give the buyer a disclosure statement and prescribed certificates before the buyer signs. The Property Law Act 2023 expressly contemplates doing this electronically. The Queensland Law Society's published guidance says section 101 permits the documents to be given by electronic communication, including by sending a link to them, provided the requirements of section 102 are met, and that the documents may be sent in separate communications and by different modes. The Government's own summary is that disclosure may be given in person, by post or electronically.

Two practical points follow. The first is order. The buyer must have the disclosure documents before signing, and where both the bundle and the contract are sent electronically on the same afternoon, the timestamps are what show which came first. A workflow that puts the disclosure documents in front of the buyer, and records that, before the contract can be signed is doing legal work.

The second is proof. The Government's guidance tells sellers they must be able to prove the disclosure statement was given. The consequence of failing is serious: a buyer who did not receive the documents before signing may terminate at any time before settlement. An electronic record of delivery is better evidence than most paper trails, as long as someone keeps it.

Deeds, companies and the end of the witness

A sale contract is an agreement, not a deed, but deeds appear around property transactions often: a deed of variation, a deed of guarantee, a deed that novates a contract to a new buyer. For centuries a deed had to be on paper, sealed and witnessed. In Queensland that is no longer so.

The change began as a temporary measure in 2020. Proctor, the Law Society's journal, reported in March 2022 that the signing changes would become permanent from 30 April 2022, and confirmed in April that the permanent reforms had commenced. The rules now sit in the Property Law Act 2023. Section 50 says a document that is to have effect as a deed may be in the form of an electronic document and may be electronically signed. Section 51 says an individual may sign a deed whether or not in the presence of a witness. Section 55 allows a deed to be signed by signing a counterpart or a true copy, so the parties need not sign the same physical or digital file.

Companies have their own provision. Under section 52, a corporation may execute a document without a seal if it is signed by two directors, by a director and a secretary, or, for a proprietary company with a sole director who is also the sole secretary, by that person. Again, no witness is needed. When a seller or buyer is a company, the question to ask of an electronic contract is not whether the signature looks official but whether the people who signed hold those offices.

Guarantees, which the law also requires to be in writing, are covered by section 69: a guarantee may meet the requirement even if it is an electronic document or digitally signed.

Where paper rules and witnesses remain

The general permission in the Electronic Transactions Act has a boundary. Schedule 1 excludes from it any requirement or permission for a document to be attested, authenticated, verified or witnessed by a person other than its author. Where some other law says a document must be witnessed, the Electronic Transactions Act does not let an electronic process replace the witness. Only a specific provision can do that, as the deed provisions in the Property Law Act now do.

The documents that change the land register are the main example in a sale. A buyer and seller do not sign a paper transfer in most transactions today. Titles Queensland describes electronic conveyancing as mandated for most transactions, and in that system the solicitors or conveyancers sign digitally on their clients' behalf, having first been authorised by the client and having checked the client's identity. The client's own electronic signature on the contract plays no part in that step.

Where a person deals with the registry directly, originals still matter. Titles Queensland's online drop box for self-represented customers accepts scanned documents, and requires the person lodging to keep the originals permanently. Scanning a signed paper form is a different thing from signing electronically, and the registry's rules are written around the former.

Changes after signing

Contracts are often altered during negotiation. On paper the convention is well known, and the Queensland Government's guidance states it: where a seller makes a counter-offer by altering the contract, both parties must initial the changes.

Electronic documents need an equivalent, because a file that has been signed and locked cannot simply be written on. There are two sound ways to make a change. One is to withdraw the document and issue a fresh version for both parties to sign again. The other, once a contract is on foot, is a separate written variation signed by both sides, which is itself a document about land and should meet the same tests of writing, signature and consent. What does not work well is an exchange of informal messages that leaves it unclear whether a term was changed, proposed or merely discussed.

Reading and keeping an electronic contract

The ease of signing is the one real hazard. A document that takes ninety seconds to sign on a phone took someone hours to prepare, and it binds as firmly as its paper ancestor. The warning statement about cooling-off, the special conditions and the reference schedule are all there on the screen, and they reward a second reading on something larger than a handset.

Keeping the record is the other habit. Each party should hold the final file, the platform's certificate of signing and the emails by which the contract and the disclosure documents arrived. Those are the electronic equivalent of the signed original in the solicitor's safe.

The law asks the same three things of a tapped signature as of an inked one: who signed, that they meant it, and that the other side agreed to receive it that way.

Queensland's rules are permissive by design. They let parties choose their method and judge it by what it proves. A buyer or seller who understands that can sign on a screen with confidence, and can also recognise the moments when a document in the same transaction still follows an older rule.
