Can a mechanic keep my car until I pay a disputed bill?
Yes — the lien doesn't care whether you agree with the bill, only whether it's been paid.
Generally, yes — garages have a long-established common law right called a repairer's lien, letting them keep your car until the repair bill is paid. This applies whether or not you agree the bill is fair: the lien is based on possession of the vehicle and non-payment, not on whether the dispute has been resolved. If you need your car back urgently but are genuinely disputing the charge, paying the bill "under protest" and pursuing a refund afterward is usually the fastest practical route, rather than waiting out the dispute with your car stuck at the garage.
What the lien does and doesn't cover
| Situation | Lien applies? |
|---|---|
| Unpaid bill for the repair just carried out | Yes — the classic case a repairer's lien is designed for |
| Bill you're disputing but haven't paid | Yes — disputing the amount doesn't defeat the lien; the garage can still hold the car |
| An unrelated, separate past debt to the same garage | Generally weaker — a lien typically attaches to the specific work on the vehicle currently held, not unconnected debts |
| Refusing to release the car even after full payment | Not lawful — once the bill is settled, there's no continuing basis to hold the vehicle |
Your underlying rights on the quality of the work
Separately from the lien question, the repair itself must still meet legal standards: performed with reasonable care and skill, completed in a reasonable time, and charged at a reasonable cost if no price was agreed in advance. If your dispute is about the quality or reasonableness of the work — not just the amount — that's the substantive issue to resolve, even while the practical question of getting your car back is handled separately.
Why "paying under protest" is often the pragmatic move
- It gets your car back immediately, without conceding the bill is actually fair.
- State clearly, in writing, at the time of payment, that you're paying under protest and reserve the right to challenge the charge.
- You can then pursue a refund of the disputed portion separately — through negotiation, a formal complaint, or small claims court if needed — without your vehicle being held hostage to the outcome.
- Waiting out a dispute with the car held at the garage can also rack up separate storage charges in some cases, which is another reason resolving access quickly is often worth it even before the substantive dispute is settled.
What to do if a garage is holding your car
- Confirm the bill relates specifically to work just done on the car currently held — not an unrelated past debt.
- If you genuinely can't afford to pay, or believe you were charged for unauthorised or substandard work, try to resolve it directly with the garage first, calmly and in writing.
- If you need the car back before that's resolved, consider paying under protest, making your objection to the charge explicit at the time of payment.
- Once you have the car back, pursue the disputed amount through a formal complaint, and small claims court if it isn't resolved.
- If the garage refuses to release the car even after full payment, that's unlawful, and you should seek advice immediately.
What does 'paying under protest' mean and how does it help? Paying under protest means paying the disputed bill in full to get your car back immediately, while clearly stating in writing that you don't accept the charge and reserve the right to challenge it afterward. This gets your vehicle released without conceding you agree the bill is fair, and you can then pursue a refund of the disputed amount separately.
Can a garage keep my car for a debt unrelated to the current repair? A repairer's lien generally only covers the specific work just carried out on the vehicle in their possession, not unrelated past debts. If a garage is holding your car over an unconnected bill, that's a weaker legal position for them, and worth challenging directly.
