What XX is for
Section 14(2) of the Land Acquisition Act 1969 (SA) applies to land under the Real Property Act 1886. The acquiring authority must serve a copy of each notice of intention to acquire land on the Registrar-General, who then enters a caveat on the title forbidding all dealings with the land without the authority's written consent. Form XX is the approved form for that caveat; its text forbids registration of dealings with the land in the attached notice of intention until the caveat is withdrawn or the court orders otherwise. The caveat is withdrawn on the authority's written application when it decides, or is presumed to have decided, not to proceed (s 14(3)). Prefix XX is used for freehold land and XX2 for a subsidiary interest.
When you need it
- An acquiring authority (a body authorised by an Act to acquire land) has issued a notice of intention to acquire land under the Real Property Act.
- The authority needs the title caveated so dealings cannot be registered without its consent while the acquisition proceeds.
- Not for private parties: a person claiming an interest in land lodges a Form C1 caveat instead.
How to fill it in
- 1

- 2
Authority

Filing, lodging and service
- Registrar-General's caveats are not on the Registrar-General's mandated electronic lodgement list, so the form is lodged on paper with Land Services SA.
- Lodge the form with the copy of the notice of intention to acquire land. Serving the copy on the Registrar-General is the authority's duty under section 14(2).
- Check Land Services SA's current fee schedule for any lodgement fee.
Common mistakes
- If the authority does not acquire the land within 18 months (or an extended period), it is presumed to have decided not to proceed (s 15(4)), and it must then apply for the caveat to be withdrawn (s 14(3)) using Form WXX.
- Owners who receive a notice of intention must tell the authority within 14 days of other people with interests in the land (s 10A).
- The Land Services SA guidance notes cite the 'Land Acquisition Act 1996'; the Act is the Land Acquisition Act 1969.
Frequently Asked Questions
Why is there a Registrar-General's caveat on my title?
Usually because an acquiring authority has served a notice of intention to acquire the land. The Registrar-General must then caveat the title so no dealing is registered without the authority's written consent (Land Acquisition Act 1969 s 14(2)).
Can I sell land that has a Registrar-General's caveat?
Dealings cannot be registered without the acquiring authority's written consent while the caveat stands. Contact the authority named in the caveat.
