CIB 280: Changes to address requirements for Western Australia’s land registry forms

Landgate uses AS 4590 – 2006 Address Standards for recording addresses for statutory and commercial purposes.

It is strongly recommended that conveyancers comply with the following basic rules from AS 4590 when entering addresses onto Western Australia’s land registry forms.

These addresses are provided to Landgate within title dealings - in both paper and electronic formats - to enter onto the Register to be primarily used for the service of any notices required to be sent to the registered proprietors.

Following these standards will significantly increase the efficiency of processing paper-based title dealings, reduce delays and assist in accurate delivery of important notices to registered proprietors. When in doubt, the format returned by the Landgate Address Verification Service, where applicable, should be used.

AS 4590 – 2006 Address Standards


Unless specifically part of the address, such as a hyphen in a range of numbers (eg 17-18), punctuation, including commas and full stops, should not be captured in address information.

Acceptable format: 1 Midland Square MIDLAND WA 6056

Post Office Box

Post Office Box information should be shown in an abbreviated format and capitalised. Private Mail Bag Service should be shown as ‘PRIVATE BAG’ and General Post Office Box should be shown as ‘GPO BOX’.

Acceptable format: PO BOX 2222 MIDLAND WA 6936

Care of

In Australia, 'Care of' is used where a letter etc. is to be delivered and entrusted to another person or company.

Consequently, ‘Care of’ should only be used on land transaction forms when immediately followed by the name of a person or company. References to ‘Care of’ should be listed in full (not as C/-).

Acceptable format: Care of Joe Citizen of PO BOX 2222 MIDLAND WA 6056

Western Australian addresses

Landgate recommends that all Western Australian (not national or international) addresses that are to be entered into the EAS2 system or into legal documents are checked for accuracy and formatting via the Address Verification Service on Landgate’s website.

Only a valid returned address should then be entered into EAS2 or the legal form. The tool contains a follow-up notification for any queries relating to failed addresses.

Please note that this service will soon be enhanced to include the state of ‘WA’ in the resulting address. Please remember to include ‘WA’ in the address until this is implemented.

Transitional implementation

The addressing standards described above are intended to apply to all paper land transaction documents in which the address for service of notices is required.

The initial focus will be on capturing the correct and consistent addresses of the transferees in transfer of land documents. In dealing cases where a mortgage follows a transfer, Landgate will apply the address of the transferee to the certificate of title.

As from Monday 1 August 2016, addresses will no longer be required in the mortgagor panel of mortgage forms lodged in paper. However, where addresses are provided they will be accepted in any format on these forms. Note, however, that mortgage documents will not then be sufficient to effect a change of the registered proprietor’s address on a certificate of title. Clients are to be directed to the appropriate form, generally NA1, where necessary.

The current Lodgement Acceptability Check (LAC) will be modified to remove the check of addresses on mortgage documents. It will continue to check that other related documents where addresses are required are consistent.

Leading up to Monday 5 September 2016, Landgate will be reviewing industry take-up and any issues presenting, with a view to subsequently introducing an appropriate compliance date in consultation with industry. Industry professionals are requested to accept the new address standards as soon as practicable. Once a compliance date has been announced, any relevant documents that do not comply with this standard will not pass the LAC and a non-compliance report will be issued.

The Land Titles Registration Practice Manual and other relevant guides will be amended as soon as practicable to reflect these new practices. Many land transaction forms are also undergoing review and clear instructions as to when addresses are required will be included.
