Legal Project Management Plan & Checklist
Purpose of this Guide: Welcome to the specialised practitioner roadmap for managing a collapsing, failing, or hazardous retaining wall dispute in Queensland. Designed explicitly for property lawyers, structural engineering advocates, and property owners, this guide addresses the complex intersection of common law, statutory building safety, and local council enforcement that governs retaining wall disputes. Additional procedural resources can be found on the Queensland Government Portal and the Queensland Legislation Registry.
Jurisdiction: This guide applies to retaining wall disputes in Queensland, Australia. Retaining walls are NOT covered by the and are excluded from dividing fence jurisdiction, unless the dividing fence is structurally dependent on the retaining wall.
Governing Legislation: The primary legal framework includes which covers Property Law Act 2023 (QLD) which covers commenced 1 August 2025, replacing Property Law Act 1974. CRITICAL REFORM: The new Act moves from the previous strict liability regime (s179/s180 of 1974 Act) to a negligence-based duty of care. Landowners must now take reasonable care to ensure they do not do anything, or omit to do anything, that adversely affects the support provided to neighbouring land. This replaces the previous strict liability for withdrawal of lateral support. Building Act 1975 (QLD) which covers building safety, compliance, and enforcement powers, Building Regulation 2021 (QLD) which covers certifiable works thresholds (walls >1m), Queensland Building and Construction Commission Act 1991 (QLD) which covers licensed builder requirements, Local Government Act 2009 (QLD) which covers council enforcement and show cause powers, Common law: natural right of support, nuisance, negligence, Neighbourhood Disputes (Dividing Fences and Trees) Act 2011 (QLD) which covers only where fence is structurally dependent on wall
Process at a Glance: Retaining wall disputes are governed by the 'benefit' principle at common law - the owner who added fill or made the cut that necessitated the retaining wall is generally responsible for its construction and maintenance. Commission a structural engineer to inspect the wall and assess the hazard level and cause of failure. Conduct a title and development approval search to determine who built the wall and which owner benefits from the fill/cut. Analyse liability under the Property Law Act 2023 (QLD) negligence-based duty of care and the benefit principle. Note: for causes of action arising before 1 August 2025, the strict liability provisions of s179/s180 Property Law Act 1974 still apply as transitional provisions. Draft and serve an urgent remedial work notice on the responsible adjoining owner, attaching the engineer's report. If the wall exceeds 1m in height, it likely requires building certification under the Building Act 1975 and Building Regulation 2021 - check whether original development approval exists. If the adjoining owner refuses to act and the wall represents a safety hazard, report to the local council building compliance officer to prompt a Show Cause or Enforcement Notice. If unresolved, file in the Magistrates Court for a structural maintenance/repair order under common law nuisance or negligence.

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).
Verify all prerequisite documentation has been obtained, cross-reference against the statutory requirements for this matter type, and confirm compliance with practice direction protocols.
Building certification threshold: Retaining walls exceeding 1m in height likely require building certification under the Building Regulation 2021 (Qld). Walls built without approval above this threshold create a compliance issue under the Building Act 1975 (Qld).
Prepare the relevant forms and supporting materials required under the applicable legislation, ensuring all mandatory fields are completed and all attachments are properly certified.
Jurisdictional distinction: Retaining walls are NOT covered by the Neighbourhood Disputes (Dividing Fences and Trees) Act 2011 (Qld) and are excluded from QCAT dividing fence jurisdiction. However, if the fence is structurally dependent on the wall, the fence component may fall within QCAT jurisdiction. If the fence is independent of the wall, the dispute is governed entirely by common law and the Building Act 1975 (Qld).
Draft and dispatch formal correspondence addressing the procedural requirements at this stage, including any required notices, requests for information, or proposals for resolution.
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.
Coordinate the collection and review of all financial documentation required for disclosure, including statements, valuations, and supporting schedules as mandated by the rules.
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.
Verify all prerequisite documentation has been obtained, cross-reference against the statutory requirements for this matter type, and confirm compliance with practice direction protocols.
CRITICAL REFORM - Property Law Act 2023 (Qld): Commenced 1 August 2025, replacing Property Law Act 1974 (Qld). The new Act moves from the previous strict liability regime (s179/s180 of the 1974 Act) to a negligence-based duty of care. Landowners must now take reasonable care to ensure they do not adversely affect the support provided to neighbouring land.
Transitional provisions: For causes of action arising BEFORE 1 August 2025, the strict liability provisions of s179/s180 Property Law Act 1974 (Qld) still apply.
Benefit principle (common law): The owner who added fill or made the cut that necessitated the retaining wall is generally responsible for its construction and maintenance.
Conduct a thorough review of all filed materials to ensure compliance with court requirements, verify service obligations have been met, and prepare for the next procedural milestone.
Assess the strategic considerations for interim applications, prepare supporting evidence, and draft the necessary documentation for urgent or time-sensitive relief sought.
QBCC licensing: If the wall exceeds 1m in height, the work may require a Queensland Building and Construction Commission (QBCC) licensed builder and a building certifier under the Building Act 1975 (Qld).
Council enforcement powers (Building Act 1975 (Qld)): Council may issue a Show Cause Notice and subsequently an Enforcement Notice requiring the owner to rectify the unsafe structure.
Prepare the relevant forms and supporting materials required under the applicable legislation, ensuring all mandatory fields are completed and all attachments are properly certified.
Council enforcement process: Council may issue a Show Cause Notice giving the owner an opportunity to respond before issuing a formal Enforcement Notice under the Building Act 1975 (Qld). The timeframe for council action varies significantly and may be too slow for imminent hazards - consider self-help remediation or urgent injunction if delay creates risk.
