For a worker, contractor, or sub-contractor seeking to rely on the Act, the first step is to ensure that the work done or materials furnished are within the scope of the Act: manual work or personal service for a worker; any work or materials for a contractor or sub-contractor. The worker or sub-contractor must identify the owner or occupier whose land is to be subjected to the lien, and must be able to prove that the owner or occupier gave assent (express or implied) to the work on the land or fixture. For a contractor’s lien, the same requirement applies.
Once wages or contract price are due and remain unpaid, the creditor should promptly give a written notice demanding payment, signed by the claimant, and delivered to the person liable (or sent by registered post to their last known address in South Australia). This triggers the seven-day period under s 10(2)(a). After the seventh day, the 28-day period for registering the lien begins. If the debtor becomes insolvent in the meantime, the time runs from that event, which may be earlier. The registration must be lodged at the General Registry Office in a form approved by the Registrar-General, with the prescribed fee and containing the prescribed information. The notice must state the court in which action will be brought (s 10(5)). If the lien is on goods under s 4(2), a separate notice under s 19 must be given, and an action commenced within 14 days of that notice.
After registration of a land lien, the claimant must commence an action against the owner or occupier in the appropriate court within 14 days (s 15). Failure to do so means the lien ceases. The action should join the person primarily liable as a defendant if judgment has not already been obtained (s 23). The claimant should be prepared to prove the work, the amount, the assent, and the registration within time.
Alternatively, the claimant can rely on a charge under s 7, which does not require registration but does require an action to be brought within 28 days after the wages or contract price become due under s 10(2). The charge attaches to money payable by the contractor or sub-contractor. However, if that money has already been paid over bona fide without notice, the charge is defeated (s 7(5)). Therefore, prompt notice of the charge to the person holding the money is advisable, though not strictly required by the Act.
For the owner or occupier who receives a notice of lien, the safest course is to withhold payment from the contractor to the extent necessary to satisfy the claim, as s 6 limits the lien to the unpaid portion. The owner may also deposit the amount claimed in court (s 16, 26) to discharge the lien and avoid further proceedings. If the amount deposited is not recovered by the lienholder within the statutory period, it is returned. The owner may also apply to the court under s 32 to cancel the claim or registration if it is vexatious or without grounds.
An owner or occupier who has paid the full contract price in good faith before receiving notice of the lien is protected to the extent that the lien does not extend beyond the unpaid portion (s 6). Therefore, it is critical for owners to obtain written acknowledgements from workers and sub-contractors that they have been paid before making final payments to the contractor.
A mortgagee who wishes to protect its security may pay the lien amount and add it to the mortgage debt (s 20). The interest is 8 per cent per annum. This may be financially prudent if the lien ranks ahead of the mortgage (but note s 9: the lien is subject to registered mortgages, so if the mortgage is registered before the lien, it retains priority; the mortgagee may still choose to pay to avoid a sale under the lien).
Practitioners should note that the Act does not require a pre-registration search, but it is prudent to search the Register Book and the index of liens under s 13 and 14 before advancing funds or completing a purchase, to ascertain whether any liens exist. The index is open for inspection on payment of the prescribed fee.
Given the low dollar cap (s 4(3) - $200), workers with larger claims will need to rely on other remedies (s 44 preserves other remedies). The lien is therefore of limited practical value for large sums; its main utility is as a pressure mechanism and a priority tool for small debts. For larger claims, a separate action for the debt or a statutory demand under corporations law may be more effective.
Finally, any person giving a notice of claim, lien, or charge should ensure they have reasonable grounds and are not acting vexatiously, to avoid liability under s 33 (criminal penalty) or s 34 (compensation). The penalties for fraudulent or vexatious claims, though modest, can still be imposed.
