Client Owes Money But No Contract: Can You Still Recover It?

You did the work. You sent the invoice. The client hasn’t paid. And there’s no signed contract.

This happens constantly—tradies finish jobs based on verbal quotes, consultants deliver projects after a few emails, freelancers complete work following a phone call. When payment doesn’t arrive, the first question is always: can I still recover the money if there’s no written contract?

Yes. Australian law recognises your right to be paid for work performed, even without a signed agreement. The legal principle is called quantum meruit—Latin for “as much as he has deserved.”

What Is Quantum Meruit?

Quantum meruit is a common law remedy that allows you to claim reasonable payment for services rendered or goods supplied when there is no enforceable contract setting out the price.

It typically applies when:

• Work was requested and performed, but no written contract was signed
• A contract existed but didn’t specify the payment amount
• A contract was partially performed before being terminated
• Services were provided under a contract that turned out to be void or unenforceable

The key requirement is that the other party requested or accepted the benefit of your work. You cannot force someone to pay for unsolicited services, but if they asked you to do the work—verbally, by email, or through conduct—quantum meruit gives you a claim.

The amount recoverable is the reasonable value of the work, not necessarily what you would have charged. Courts assess this by looking at industry rates, the complexity of the work, the time involved, and what similar providers charge for comparable services.

Common Scenarios Where Quantum Meruit Applies

Verbal agreements: You quote a price over the phone, the client says “go ahead,” and you complete the work. The verbal agreement created an expectation of payment. If the client refuses to pay, you can claim quantum meruit based on the agreed price or, if disputed, the reasonable market value.

Email instructions without formal terms: A client emails asking you to start a project. You send a proposal or quote, they reply “sounds good,” and you proceed. The email trail demonstrates the client’s request and acceptance of your services.

Ongoing work relationships: You’ve worked with a client for months without a formal contract. Each time they request work, you deliver, and they pay. If payment suddenly stops, the established pattern supports a quantum meruit claim for the outstanding invoices.

Abandoned or terminated contracts: A signed contract exists, but the client terminates the arrangement early or the contract becomes void. You can still claim quantum meruit for the work completed up to that point.

What Evidence Do You Need?

Your Letter of Demand must be backed by evidence that proves:

1. The client requested the work — emails, text messages, meeting notes, verbal instructions confirmed in writing
2. You performed the work — invoices, timesheets, photos, delivery receipts, project files
3. The client accepted or benefited from the work — emails acknowledging completion, use of the deliverables, payment of earlier invoices
4. The reasonable value — your quote or proposal, industry rates, comparable pricing from competitors

The stronger your evidence trail, the more likely the client will pay without further dispute. Even informal communications—text messages, WhatsApp chats, verbal quotes confirmed by email—can establish the existence of an agreement.

How to Structure Your Letter of Demand

A Letter of Demand for a quantum meruit claim follows the same structure as a standard demand letter, with specific adjustments to address the absence of a formal contract.

State the facts clearly: Open with a direct summary: “On [date], you requested that I [describe the work]. I completed the work on [date] and invoiced you $[amount] on [date]. Payment has not been received.”

Reference quantum meruit explicitly: Include a sentence like: “In the absence of a signed contract, I am entitled to recover the reasonable value of the services provided under the principle of quantum meruit, a recognised remedy under Australian common law.”

This signals that you understand the legal basis of your claim.

Attach your evidence: List the documents you are attaching—copies of emails or messages requesting the work, your quote or proposal, invoices, proof of delivery or completion, and any correspondence where the client acknowledged the work.

Specify the amount and deadline: “I demand payment of $[amount] within 7 days of the date of this letter. If payment is not received by [specific date], I will commence recovery proceedings without further notice.”

The 7-day period is standard for straightforward quantum meruit claims. For larger amounts or more complex disputes, 14 days may be more appropriate.

What Happens After You Send the Letter?

Most clients pay after receiving a properly drafted Letter of Demand. The formal tone, the legal references, and the clear deadline create urgency.

If they do not pay, your options include:

• Negotiate a payment plan — if the client has cash flow issues but acknowledges the debt
• File a tribunal claim — for amounts up to $10,000 (NSW, Vic), $25,000 (Qld), or the relevant limit in your state
• Engage a debt collector — if you prefer not to pursue the matter yourself
• Issue a statutory demand — if the debtor is a registered company and the debt exceeds $4,000

The Letter of Demand is the first formal step. It is often the only step required.

When You Should Speak to a Lawyer

Quantum meruit claims are straightforward when the facts are clear and the amount is modest. Seek legal advice if:

• The amount exceeds $25,000
• The client is disputing that they requested the work
• There is a written contract, but it is ambiguous or partially performed
• The client is insolvent or has a history of non-payment
• You are a contractor claiming against a builder or head contractor (construction law has specific rules)

A lawyer can assess whether quantum meruit is the strongest claim or whether you have other remedies available.

Final Checklist Before Sending Your Letter

Before you send your Letter of Demand, confirm:

• You have evidence the client requested the work
• You have proof you completed the work
• You have invoiced the client and they have not paid
• The amount you are claiming is reasonable (industry rates, your quote, or comparable pricing)
• You have attached all relevant documents
• The letter specifies a clear deadline (7 or 14 days)
• The letter is addressed to the correct person or entity

Once sent, keep a copy of the letter, proof of postage, and any email delivery receipts. If the matter proceeds to tribunal or court, you will need to prove the letter was served.

Frequently Asked Questions

Can I claim payment if there was no written contract at all?

Yes. Australian law recognises quantum meruit, which allows you to recover the reasonable value of work performed even without a signed contract. You need evidence that the client requested the work and that you completed it.

What if the client says they never agreed to pay that amount?

If the amount is disputed, quantum meruit allows you to claim the reasonable market value of the services. Courts assess this by looking at industry rates, the complexity of the work, and what similar providers charge. Your quote or proposal is strong evidence, but not the only factor.

Does quantum meruit apply to goods as well as services?

Yes. Quantum meruit covers both goods supplied and services rendered. If you delivered materials or products without a formal contract, you can claim the reasonable value of those goods if the client requested and accepted them.

How long do I have to make a quantum meruit claim?

In most Australian states, the limitation period for quantum meruit claims is six years from the date the work was completed. However, it is always better to act quickly—evidence degrades, clients become harder to locate, and debts become harder to recover over time.

What if the client ignores my Letter of Demand?

If the client does not respond or pay within the deadline, you can file a claim in your state’s civil tribunal (for amounts up to the tribunal limit) or commence court proceedings. You can also engage a debt collector or, if the debtor is a company owing $4,000 or more, issue a statutory demand.
