The RCLSA introduces the concept of freedom of testation into the customary law of succession.

In terms of the RCLSA a spouse of a deceased in a substitute marriage is considered as a descendant of the deceased.

The RCLSA recognises the application of the Intestate Succession Act to woman-to-woman marriages in terms of customary law.

The RCLSA excludes the working of the Intestate Succession Act 81 of 1987 in the case of a deceased married in terms of customary law.
