Legal Project Management Plan & Checklist
Use this fork when a retaining wall on or near the boundary between two properties is failing, collapsing, or poses an imminent safety hazard, and the neighbouring owner is refusing to take action. Open this fork immediately when an engineer or the local council reports an imminent structural failure risk. Note that retaining walls are NOT covered by the Neighbourhood Disputes Act and QCAT does not have jurisdiction - this fork proceeds through common law, local council enforcement, and the Magistrates Court.
Jurisdiction: Queensland. Retaining wall disputes are governed by common law nuisance and negligence and the Property Law Act 2023 (QLD), which replaced the strict liability regime of the old Act with a negligence-based duty of care from 1 August 2025. Local council building compliance officers may issue Show Cause and Enforcement Notices under the Building Act 1975. Urgent structural repair orders may be sought in the Magistrates Court.
The Process at a Glance: A structural engineer is immediately engaged to inspect the wall, assess the hazard level, and identify the cause of failure. A title and development approval search is conducted to determine who built the wall and which landowner benefits from the fill or cut that necessitated it - the benefiting owner is generally responsible at common law for construction and maintenance. Liability is analysed under the Property Law Act 2023 (QLD) negligence-based duty of care standard (for events occurring after 1 August 2025) or the strict liability provisions of the old Act (for events occurring before that date). An urgent remedial work notice is drafted and served on the responsible adjoining owner, attaching the structural engineer's report. If the wall exceeds 1m in height, compliance with the Building Act 1975 and Building Regulation 2021 is assessed and, if required, council building certification is confirmed. If the adjoining owner refuses to act and the wall is a safety hazard, the local council building compliance officer is notified to prompt a Show Cause or Enforcement Notice. If the situation remains unresolved, proceedings are filed in the Magistrates Court for a structural maintenance and repair order under common law nuisance or negligence.
Key Legislation and Case Law: Property Law Act 2023 (QLD) - commenced 1 August 2025, replacing the Property Law Act 1974; introduces a negligence-based duty of care for lateral support of neighbouring land (the owner must take reasonable care not to do anything, or omit to do anything, that adversely affects the support provided to neighbouring land); for causes of action arising before 1 August 2025, the strict liability provisions of the Property Law Act 1974 ss179-180 remain applicable as transitional provisions. Building Act 1975 (QLD) - building safety and compliance; walls over 1m in height typically require building certification. Building Regulation 2021 (QLD) - certifiable works thresholds (retaining walls over 1m). Local Government Act 2009 (QLD) - council enforcement powers including Show Cause and Enforcement Notices for unsafe structures. Queensland Building and Construction Commission Act 1991 (QLD) - licensed builder requirements for retaining wall construction and repair. Common law: the benefit principle establishes that the owner whose fill or excavation necessitated the retaining wall is generally responsible for its construction and maintenance, regardless of which side of the boundary the wall is physically located on.

This legal matter plan provides a structured workflow for REAL_ESTATE cases, outlining the standard DISPUTE_LITIGATION process. Utilize these tracking templates to manage your legal cases efficiently.
Commission a structural engineer to inspect the retaining wall, assess the hazard level, determine the cause of failure, check for fence dependency, and confirm whether the wall exceeds 1m (requiring building certification under the Building Act 1975 QLD).
Analyse liability under the Property Law Act 2023 (QLD) negligence-based duty of care (replacing strict liability under s179/s180 Property Law Act 1974), determine which owner is responsible for the cut/fill under the benefit principle, and serve an urgent remedial work notice on the responsible party.
If the responsible owner refuses to act, report the unsafe structure to local council building compliance to prompt a Show Cause or Enforcement Notice under the Building Act 1975 QLD.
If council enforcement is insufficient, file in the Magistrates Court for a structural repair order under common law nuisance/negligence, or resolve through negotiated agreement.
