A subdivision certifier is the registered professional who assesses and issues the certificates that turn approved plans into separate legal titles.
Southwell Certifiers is a registered subdivision certifier working across New South Wales. We issue Subdivision Certificates, Subdivision Works Certificates, subdivision CDCs and Compliance Certificates, and we respond to every submission within two business days.
Areas we service: we certify subdivisions across Sydney and regional NSW. For duplex and dual occupancy projects in Sydney’s busiest CDC subdivision market, see our Subdivision Certifier Canterbury-Bankstown page.
What We Certify
We perform subdivision certification functions under the NSW planning legislation. Depending on your project and approval pathway, that covers:
- Subdivision Complying Development Certificates (CDC) for the subdivision component of a complying development
- Subdivision Works Certificates (SWC) for the civil works
- Subdivision Certificates, the final approval before titles can register
- Compliance Certificates for subdivision design and construction
- Site inspections through the construction phase
In plain terms, we make sure the approval, the plans and the completed works meet the legal and technical requirements, and we issue the certificates that let the plan register.
What We Can Do On Your Project
The certification pathway depends on how your development was approved. The two routes work differently and it is worth knowing which one you are on.
Duplex and multi-dwelling developments under CDC
If your duplex or multi-dwelling project is approved under Complying Development, we can:
- issue the Subdivision CDC for the subdivision component
- issue the Subdivision Certificate once the requirements are met
Both approvals sit with us, which is why this pathway is usually the faster one. There is no handover between parties and no second queue to join.
DA and State Significant Development projects
If your project was approved by Development Application or as State Significant Development, we can:
- issue the Subdivision Works Certificate where permitted
- inspect the subdivision works
- issue Compliance Certificates for the works
- issue the Subdivision Certificate (SSD)
- review your Subdivision Certificate package (DA)
For DA approved developments the consent authority must permit a registered certifier to carry out the function. We confirm that at the fee proposal stage so there are no surprises later.
When You Need a Subdivision Certifier
You need one whenever approved plans have to become separate titles. Common triggers:
- subdividing a duplex or dual occupancy in NSW
- Torrens title subdivision
- strata subdivision of townhouses or a residential flat building
- multi-dwelling housing developments
- land subdivisions approved by DA
- a consent condition requiring a Subdivision Works Certificate before civil works start
- works complete and titles held up pending the Subdivision Certificate
Building approval deals with the building. If you want two separate titles, the subdivision side needs handling in its own right. That is the part we do.
Engage Us Early, Not At The End
The best time to bring in a subdivision certifier is at design stage, before the drawings are finalised.
On CDC duplex and multi-dwelling projects
Early advice tells you whether the development qualifies for subdivision via CDC at all, and flags the design choices that would rule it out. Those choices are cheap to change on paper and expensive to change on site.
Where your consent requires an SWC
Engaging us straight after approval identifies what documents are needed, what works need certification, which conditions affect timing, and what is likely to hold up the SWC or the final subdivision steps.
Most of the rework we see comes from conditions that were visible at approval and only got read months later.
Registered Certifier Or Council
Both can act as the certifying authority. The full comparison of certifier versus council goes into more detail. The statutory function is the same and the law is the same. The difference is in how the work gets handled.
Councils carry planning, engineering, compliance and public responsibilities across an entire LGA, so a subdivision file moves between departments and joins a queue behind everything else.
We are engaged for the certification role on your project specifically. That means direct contact with the certifier assessing your design, clearer guidance on documentation, and faster responses.
Faster does not mean looser. A registered certifier is bound by the same statutory requirements and the same professional standards. It means knowing the rules well enough to manage the process properly.
How Long It Takes, And What It Costs
We respond within two business days. Every submission comes back inside that window, either issued or answered with a specific list of what is outstanding. You will not be left wondering where your application sits.
That is our part of the timeline. The overall subdivision duration depends on things no certifier controls: how long construction runs, how quickly authority clearances come back, and the current queue at NSW Land Registry Services. We set a realistic expectation at the fee proposal rather than guessing here.
What the fees depend on
Lot count, subdivision type, the number of inspections and whether you are on a CDC or DA pathway. There is no standard schedule. Request a fee proposal and you get a fixed figure against a defined scope.
Why Developers Use Southwell Certifiers
You deal with the certifier directly. Dean Dehghan-Khalaji is a Chartered Professional Engineer (CPEng) and Registered Certifier BDC 05320, listed on the National Engineering Register and a member of the Association of Australian Certifiers. The person assessing your design is the person who answers the phone.
Engineering judgement, not box-ticking. Subdivision certification is a civil engineering problem before it is an administrative one. Drainage, road geometry and detention design get assessed by someone who has designed them.
Two business days, consistently. Issued, or answered with exactly what is outstanding.
Independent. Not tied to a council’s internal timetable and not queued behind a large firm’s workload.
Across NSW. We certify subdivisions across Sydney and regional New South Wales, working with councils throughout the state.

Frequently Asked Questions
Who can issue a subdivision certificate in NSW?
Either the local council or a registered certifier accredited for subdivision work. The certifier must hold the correct registration class for the type of subdivision. A registered private certifier issues the same statutory certificate council would, under the same legislation.
How much does a subdivision certifier cost in NSW?
Fees depend on lot count, subdivision type, the number of inspections required and whether the project runs through a CDC or a DA. There is no standard schedule. A fee proposal against a defined scope is the only reliable figure.
What is the difference between a Construction Certificate and a Subdivision Works Certificate?
A Construction Certificate covers building work. A Subdivision Works Certificate covers the civil infrastructure serving a subdivision: roads, drainage and utility services. A project with both buildings and subdivision works usually needs both.
How do you become a subdivision certifier in NSW?
Registration requires a recognised degree in civil engineering or surveying, several years of relevant industry experience, professional indemnity insurance, and registration through the NSW certification framework. Registration classes are specific, so a certifier registered for one type of work is not automatically registered for subdivision.
Do I need a subdivision certifier for a duplex?
Yes, if you want separate titles. Building the duplex and subdividing it are two separate approvals. The subdivision needs its own certificate whether the pathway is a CDC or a DA.
Can a private certifier issue a Subdivision Works Certificate?
Yes. A registered certifier with the appropriate class can issue an SWC, and it is usually faster than going through council.
When should I engage a subdivision certifier?
At design stage, before the civil drawings are finalised. Most rework comes from conditions that were visible early and read late.
