The characteristics of an abstract system for the transfer of property in South African law as distinguished from a casual system
Abstract
Two divergent systems are usually differentiated between when it comes to the way
in which real rights are transferred from one person to another, namely abstract and
causal systems. In this article the features of each system, the respect in which they
differ from each other, and the practical implications of the distinction are
established. It appears that in a causal system real rights are transferred by
conclusion of the obligatory agreement, which should be valid and enforceable. The
mutual intention to transfer and to receive real rights is not construed as an
independent real agreement as it is contained in the obligatory agreement. In a
causal system the transferor finds himself in a favourable position in relation to other
parties while bona fide third parties undoubtedly get the worst of the deal since they
have no protection against the disadvantageous consequences of delivery owing to
a void obligation.
In an abstract system the obligatory agreement is not sufficient for the transfer of real
rights, the thing should also be delivered and there should be a valid real agreement
which consists merely of the mutual intention to transfer and to receive real rights.
The real agreement is a characteristic of an abstract system which distinguishes it
from a causal system. Compared with the position of those in the causal system, the
transferee and third parties find themselves in a favourable position vis-à-vis the
transferor.
In a causal system the concept iusta causa refers to a valid and enforceable
obligatory agreement or other juridical fact which obliges the transferee to deliver thething. In an abstract system it serves no purpose to describe the causa with
reference to the obligatory agreement, since it is not a substantive law requirement
for the transfer of real rights. The causa concept refers rather to the mutual intention
to transfer and to receive real rights, which is nothing less than the real agreement.
Since the causa is contained in the real agreement it is no longer of any use in an
abstract system and should be abandoned.
The Dutch system displays the characteristics of an abstract system in that a
separate act of delivery should exist and a valid real agreement is a requirement for
the transfer of real rights. On the other hand it also displays characteristics of a
causal system, since a valid obligatory agreement is a requirement for the transfer of
real rights.
