Dental deposits and prepayments: what happens if you change your mind

Whether a dental deposit or prepayment comes back depends on why treatment stops, so this guide explains change of mind, unfair contract terms and services with a major problem.

Say you paid a deposit to start veneers or aligners, then decided not to go ahead. Whether any of that money comes back depends far less on the word "non-refundable" printed on the form than on why the treatment is stopping. Under the Australian Consumer Law, deciding you no longer want something is handled very differently from a service that was not delivered as promised, and most disputes about dental deposits turn on which of those two situations you are in.

Changing your mind is not covered by the consumer guarantees

The Australian Competition and Consumer Commission (ACCC) is clear that consumers are not entitled to a refund, repair or replacement under the consumer guarantees simply because they changed their mind. The guarantees exist to deal with things that go wrong, not with second thoughts.

The ACCC adds an important qualification: if a business has a change of mind policy, it must follow it. So in a change of mind situation, the useful question is rarely "what does the law entitle me to?" It is "what did this practice tell me its policy was, and is it sticking to it?"

That makes the paperwork at the start matter a great deal. A practice that explains its cancellation and refund terms clearly before you pay, and puts them in writing, has made a promise it has to keep. A practice that never explained them has a much weaker footing.

A "no refunds" clause cannot override your rights

The ACCC says it is illegal for businesses to rely on store policies or terms and conditions that deny consumers their rights under the consumer guarantees, and it gives "no refunds or exchanges on sale items" as an example. Businesses also cannot take away a consumer's right to a remedy when a service is faulty.

In practice this means a "non-refundable" clause has two possible jobs. If it is being used to describe the practice's own change of mind policy, it can work, and the practice is bound by it too. If it is being used to block a refund for a service that had a genuine problem, it does not work, because the law does not allow those rights to be signed away.

Unfair contract terms: the three questions a court asks

Consent and cancellation forms handed to every patient on the same pre-printed terms are likely to be standard form contracts, and the unfair contract terms laws can apply to them. Consumer protection regulators describe the test in three parts. A term is unfair if it would cause a significant imbalance in the rights and obligations of the two sides, if it is not reasonably necessary to protect the legitimate interests of the business, and if it would cause the consumer financial or other detriment if it were relied on.

A clause that lets a practice keep every dollar if you cancel, while saying nothing about what happens if the practice cancels, is the kind of one-sided term that test is aimed at. So is a term buried in small print that was never explained. How clearly a term was written and presented matters.

Only a court can decide that a particular term is unfair. If it does, the term is treated as if it never existed, and the rest of the contract carries on without it where it can. No article, regulator summary or practice can tell you for certain that a specific clause is or is not unfair.

When the treatment is the problem, the rules change

If a service has a major problem, the ACCC says the consumer can choose to cancel the contract and get a refund. It may not be a full refund, because you can be asked to pay a reasonable amount for work that was already done properly. If you paid upfront, you are entitled to some money back, and how much depends on how much of the service had problems or was never provided.

For staged dental treatment, that gives a workable way of thinking about it. Stages completed properly are payable. Stages not yet started are not. Work that was done but did not meet the consumer guarantees is a separate question, and the remedies for that sit with the guarantees, not with the practice's cancellation policy.

There is also a rule for when the business is the one that changes things. The ACCC says that if a business makes a material change to the service it agreed to provide, it should tell customers as early as possible, seek their consent, and cancel and refund customers who do not agree. A practice that changes the materials, the clinician or the scope of a plan in a way that matters should be asking you first.

Deposits, prepayments and money already spent

The two words are often used as if they mean the same thing. A deposit is generally a part payment to secure a booking or a commitment. A prepayment is money paid ahead of time towards the treatment itself.

The difference becomes concrete in dentistry because costs are incurred at different points. Once a laboratory has made a crown, aligners or a night guard to your measurements, that cost has been spent and cannot be recovered. If a later stage never happened, nothing has been spent on it. A fair conversation about a refund is usually a conversation about exactly what had been incurred, and when.

Two things often presented as rules are not. The idea that a non-refundable deposit is enforceable as long as it is reasonable and proportionate to the business's real loss comes from legal commentary on general contract principles, not from regulator guidance written for dental patients. And the common "48 hours' notice" requirement for cancelling appointments is an industry convention, not a legal standard. Both may be relevant, but neither settles your situation on its own.

There is no automatic cooling-off period for a treatment plan

Many people expect a cooling-off period after agreeing to a large purchase. The automatic cooling-off right in the Australian Consumer Law applies to unsolicited sales, such as door-to-door and telemarketing sales, where the ACCC says the period is 10 business days. For purchases made in a store, there is no automatic right to cool off, and agreeing to a treatment plan at a dental practice falls into that second group.

Some practices choose to offer a cooling-off period anyway. If yours does, ask for it in writing, and the practice must then honour it.

How common situations usually play out

What happened Change of mind? What generally applies A useful question to ask
You cancel before anything has been made or ordered Usually yes The practice's own change of mind policy, which it must follow What does the policy say, and what has actually been spent so far?
You cancel after a custom laboratory item was made Usually yes The policy, with the real cost already incurred being relevant What was made and when, and can I have the item or its records?
You stop partway through a staged plan Depends on why If the work met the guarantees, the policy; if not, consumer guarantee remedies Which stages are complete, and how is the balance worked out?
You miss an appointment without notice Treated as change of mind The practice's stated fee, if it was clearly disclosed; the term itself can be tested for fairness Where was this fee explained before I agreed?
The practice cancels or cannot provide the treatment No Money paid for services not delivered is a different matter from change of mind What will be refunded, and by when?
The practice makes a material change to the plan No The business should seek consent and refund those who do not agree What changed, and what happens if I do not accept it?
The treatment has a major problem No You may cancel and get money back, less a reasonable amount for work properly done Can you set out in writing what you consider was properly completed?

Financial consent is a professional duty, not just good manners

Consumer law is only part of the picture. The Dental Board of Australia's Code of conduct sets out requirements for obtaining patients' financial consent, and the Australian Dental Association's policy statement on informed financial consent describes a written quotation, with the patient's acceptance recorded before treatment, as good practice. The same policy says patients should be given time to consider out-of-pocket costs before treatment begins, and that estimates should make clear the cost may change if more is needed.

A deposit taken without that conversation is a weak position for a practice in more ways than one. A clear written estimate also protects you, because if a disagreement arises later, the record of what was agreed usually settles it quickly. Our guide to informed financial consent and written quotes covers what an estimate should include, and how to read an itemised dental invoice explains the item numbers on it.

If a health fund is part of the equation, what you expected to pay may also depend on provider arrangements, which we explain in preferred provider dentists and the gap. And if cost is the real reason for cancelling, it is worth asking whether treatment can be staged or paid over time before walking away. Our article on dental payment plans and affording treatment describes the usual options.

If you cannot sort it out with the practice

Put your questions to the practice in writing, and be specific: what was paid, what was done, what was made, and what the written terms said. Many of these disagreements come down to information that was never recorded, and a calm, specific request often resolves them.

If it does not, refund and pricing disputes go to your state or territory consumer protection agency, which in New South Wales is NSW Fair Trading. Concerns about the quality of care or a practitioner's conduct follow a different path: in NSW, that is the Health Care Complaints Commission. A community legal centre can help if you need advice on your own circumstances. Our page on how to make a complaint about dental treatment in NSW sets out each route.

What patients ask about deposits

Can a practice keep my deposit if I cancel?

It depends on what was agreed, what the practice's policy says and what costs had actually been incurred. A change of mind does not give you a right to a refund under the consumer guarantees, but the practice must follow its own policy, and a one-sided term can be challenged as unfair.

Are non-refundable deposits legal?

There is no simple yes or no. Terms cannot remove consumer guarantee rights, and blanket "no refunds" policies are not allowed. Whether a particular non-refundable term is unfair is something only a court can decide.

What happens to money I paid if I stop halfway?

If the treatment had a major problem, you may be able to cancel and get money back, less a reasonable amount for work properly done. If the work was fine and you have changed your mind, the practice's policy applies, and the practical question is what has already been spent.

Can a practice charge for a missed appointment?

Many practices have a policy on this, and they must apply it as stated. Whether a particular fee term holds up depends on the facts, including how clearly it was explained before you agreed.

Most of these problems never arise when the plan, the stages and the costs are written down and explained before anything starts. That is how we approach treatment planning at Lumi Dental in Melrose Park, where we are open Monday to Saturday. See our current offers or book a visit.
