You hired a contractor. They did the work. You paid a deposit. Then they disappeared — or delivered substandard work — and you never got a signed contract.
Can you still recover your money? Yes. Australian contract law does not require a signature for a binding agreement. What matters is whether the parties agreed to essential terms and whether consideration was exchanged.
Why a signature is not required under Australian law
A contract is formed when there is an offer, acceptance, consideration (something of value exchanged), and an intention to create legal relations. None of those elements require a signature.
Verbal contracts are enforceable. So are contracts formed by email, text message, or conduct. The difficulty is proving what the terms were, not whether the contract exists.
What counts as evidence when there’s no signed contract
Courts and tribunals typically accept the following as evidence:
Emails and text messages — Any exchange where the contractor agreed to do the work, specified a price, or acknowledged the scope. Messages referring to “our agreement” or “the job” demonstrate mutual understanding.
Quotes and proposals — An unsigned quote that was accepted (verbally or by conduct) can form the contract. Replying “yes, go ahead” or paying a deposit is acceptance.
Invoices — An invoice issued by the contractor acknowledges they performed work and expect payment. It is also evidence of the agreed price.
Bank transfers and payment records — Proof that you paid a deposit or progress payment shows both parties acted as if a contract existed.
Witness statements — Anyone present when you discussed the job can provide a statement confirming what was agreed.
Conduct — If the contractor turned up, started work, and invoiced you, their conduct demonstrates they believed a contract existed.
How to reconstruct the agreement after the fact
If the contractor is disputing what was agreed, reconstruct the terms from available evidence.
Collect all correspondence. Pull every email, text, WhatsApp message, and voicemail. Look for any reference to price, scope, timeline, or materials.
Print bank statements showing payments. Highlight every transfer to the contractor. Note the date, amount, and any reference or description you included.
List what was delivered (or not delivered). Be specific. If they were meant to install 10 windows and only installed 6, document that. If the work is defective, take photos and get a quote from another contractor to fix it.
Identify any witnesses. Anyone who heard the conversation, saw the quote, or was on site during the work can provide a witness statement.
Check for an Acknowledgment of Debt. If the contractor has sent any message admitting they owe you money — even a text saying “I’ll pay you next week” — that is an acknowledgment. It can reset the limitation period and strengthen your claim.
When an Acknowledgment of Debt helps your case
An Acknowledgment of Debt is a written statement where the debtor admits they owe a specific amount. It does not need to be a formal legal document. A text message, email, or handwritten note can qualify.
Why it matters:
- It proves the debt exists, even without a signed contract
- It can extend the limitation period (typically 6 years from the date of acknowledgment in most states)
- It makes it harder for the contractor to dispute the amount later
If the contractor has already acknowledged the debt informally, you can formalise it by preparing an Acknowledgment of Debt document and asking them to sign it. If they refuse, the informal acknowledgment is still evidence.
What to do if the contractor denies the agreement
If the contractor claims there was no contract, or disputes the terms, escalate.
Send a Letter of Demand. A Letter of Demand sets out your version of the agreement, the evidence supporting it, and a deadline for payment. It gives the contractor one final chance to settle before you take formal action.
File a tribunal claim. If the amount is under the tribunal limit in your state (typically $10,000 to $25,000), you can file a claim in the relevant civil and administrative tribunal. You do not need a lawyer. The tribunal will assess the evidence and make a binding order.
Engage a lawyer for larger claims. If the amount exceeds the tribunal limit, or if the contractor is defending aggressively, you may need to file in a higher court. For complex or high-value disputes, consult a qualified Australian lawyer.
Common mistakes that weaken your claim
Waiting too long. Limitation periods apply even without a signed contract. In most states, you typically have 6 years from the date of breach to bring a claim. If the contractor acknowledged the debt in writing, the 6 years usually runs from the date of that acknowledgment.
Accepting vague excuses without documentation. If the contractor says “I’ll fix it next week” or “I’ll pay you when I get paid,” get it in writing.
Paying cash with no receipt. Always pay by bank transfer and keep records. If you paid cash, get a receipt or ask the contractor to confirm receipt by text or email.
Not keeping evidence. Delete nothing. Even a message that seems irrelevant now might prove critical later.
Threatening without following through. If you send a demand letter and do nothing when they ignore it, you lose credibility.
How ClaimDone helps when there’s no signed contract
ClaimDone is built for situations like this. You upload the evidence you have — emails, quotes, invoices, bank transfers, photos of defective work — and our Proprietary AI Engine analyses it to reconstruct the agreement.
For debt recovery:
- Letter of Demand — Drafted citing contract law principles, delivered automatically for $79
- Acknowledgment of Debt — Prepared based on the evidence, ready for the contractor to sign, $79
For tribunal claims:
- Tribunal Application — All forms, statement of claim, and supporting affidavit prepared for filing, state-specific, $197
For settlement:
- Deed of Settlement — If the contractor offers to pay in instalments or settle for a reduced amount, we prepare a binding settlement deed, $97
All services are flat-fee, no subscription, Australia-wide. Most documents are ready within 60 minutes.
What happens if they still refuse to pay
If the contractor ignores your demand letter and you file a tribunal claim, they typically have 28 days to respond. If they do not respond, you can apply for a default judgment.
If they do respond and dispute the claim, the tribunal will schedule a hearing. You present your evidence — the emails, quotes, invoices, bank transfers, witness statements. The contractor presents theirs. The tribunal member makes a decision.
If you win, the tribunal issues an enforceable order. If the contractor still does not pay, you can enforce the judgment through wage garnishment, bank account seizure, or property liens.
ClaimDone prepares all the documents you need to present your case clearly. We do not represent you at the hearing or provide legal advice.
Final checklist: Recovering money without a signed contract
- Gather all emails, texts, quotes, and invoices
- Print bank statements showing payments
- Document what was delivered vs what was promised
- Identify any witnesses who can confirm the agreement
- Look for any written acknowledgment of the debt
- Send a Letter of Demand citing the evidence
- Prepare an Acknowledgment of Debt if the contractor is willing to settle
- File a tribunal claim if they do not respond
- Enforce the judgment if you win
The absence of a signed contract is an obstacle, not a dead end. Australian law recognises agreements formed by conduct, correspondence, and payment. If you can prove the essential terms and show that both parties acted as if a contract existed, you have a claim.

Frequently Asked Questions
Is a verbal contract legally binding in Australia?
Yes. A verbal contract is enforceable if there was an offer, acceptance, consideration, and an intention to create legal relations. The difficulty is proving what was agreed. Evidence such as emails, text messages, invoices, and witness statements can support a verbal contract claim.
Can I recover money from a contractor who didn't sign a quote?
Yes, if you accepted the quote and the contractor started work or you paid a deposit. Acceptance can be shown through conduct (paying, allowing them to start) or written confirmation (email, text). The quote itself is evidence of the agreed price and scope.
What is an Acknowledgment of Debt and do I need one?
An Acknowledgment of Debt is a written statement where the debtor admits they owe a specific amount. It can be formal or informal (even a text message counts). It strengthens your claim, can extend the limitation period, and makes it harder for the debtor to dispute the amount later.
How long do I have to recover money from a contractor in Australia?
Typically 6 years from the date of breach under most state limitation laws. If the contractor acknowledges the debt in writing after the breach, the 6-year period may restart from the date of that acknowledgment. Do not wait — the longer you delay, the harder it becomes to prove your claim.
What evidence do I need to prove a contract existed without a signature?
Emails, text messages, quotes, invoices, bank transfers, witness statements, and any conduct showing both parties acted as if a contract existed. The more documentation you have, the stronger your claim. Even informal messages like ‘I’ll start Monday’ or ‘Here’s the invoice’ are evidence.
