In property transactions within developments, many practitioners and purchasers are familiar with the traditional Offer to Purchase (OTP) structure. However, in certain developments there is an alternative mechanism that can provide significant benefits to both the developer and the purchaser: a Section 20 transaction in terms of the Alienation of Land Act 68 of 1981.
Understanding the difference between these two approaches can be critical when structuring property transactions within a development.
Section 20 of the Alienation of Land Act 68 of 1981 regulates the sale of a unit in a development scheme before the scheme is formally opened or before the sectional plan has been registered.
In essence, it allows a developer to sell a future sectional title unit, even though the sectional title register has not yet been opened at the deeds office.
This means that the purchaser is buying the right to obtain transfer of the unit once the sectional title scheme is registered.
In a normal OTP transaction:
A major advantage is that developers can secure buyers before the development is completed.
This improves:
Banks and financiers often prefer seeing strong pre-sales in a development, which Section 20 transactions facilitate.
Purchasers can secure a unit at an early stage and often at a more favourable price compared to purchasing once the development is completed.
Early purchasers frequently benefit from:
Section 20 imposes strict formal requirements to protect purchasers.
These typically include:
These provisions are specifically designed to prevent abuse in off-plan developments.
The Section 20 framework ensures that the development process follows a clear legal path, typically involving:
This structured process provides predictability for both developers and purchasers.
A Section 20 agreement is particularly appropriate when:
Once the scheme is registered, transactions revert to the more traditional OTP structure.
While a traditional OTP remains the most common mechanism for property transfers, Section 20 transactions are an essential legal tool in the development space. When properly structured, they create a balanced framework that allows developers to launch projects while still protecting purchasers.
For developers, investors, and practitioners involved in sectional title developments, understanding the benefits of Section 20 transactions can unlock opportunities and ensure that developments are structured both efficiently and legally soundly.
