Plan of Redefinition
Re-establishing correct boundaries.
Professional Plan of Redefinition in Sydney CBD, Northern Beaches, Wollongong & Sutherland Shire
A Plan of Redefinition is essential when existing property boundaries require formal redefinition due to historical inconsistencies, lost or unreliable survey marks, or discrepancies between occupation and title dimensions. At Onesight Surveys, Plans of Redefinition are prepared by NSW Registered Land Surveyors, ensuring accurate, compliant outcomes across Sydney CBD, Northern Beaches, Wollongong, Sutherland Shire, and throughout NSW.
Older subdivisions or historical surveys may contain measurement inaccuracies. Our Plan of Redefinition re-establishes boundaries using modern surveying standards, ensuring clarity, legal certainty, and compliance for future property transactions, development, or dispute resolution.
What is a Plan of Redefinition
A Plan of Redefinition formally re-establishes property title boundaries when survey marks are lost, historical survey data is inconsistent, title dimensions require clarification, or modern surveying accuracy is required.
Key features of a Plan of Redefinition include:
- Historical research on deposited plans and survey records
- Boundary re-establishment using high-precision survey equipment
- Preparation of a formal Plan of Redefinition certified by a NSW Registered Land Surveyor
- PDF and CAD plans suitable for lodgement with NSW Land Registry Services
- Optional consultation for council or legal requirements
Why a Plan of Definition is Critical
A Plan of Redefinition is critical because it helps resolve boundary uncertainty, supports development and property transactions, and ensures land boundaries meet modern NSW cadastral standards by:
- Rectifying historical survey inconsistencies
- Strengthening legal and cadastral certainty
- Supporting future development or subdivision
- Preventing neighbour disputes and transaction issues
- Aligning boundaries with current NSW surveying standards
Across Sydney CBD, Northern Beaches, Wollongong, Sutherland Shire, and NSW, councils and legal authorities rely on these plans to ensure property boundaries are accurate and defensible.
