The binding legal principles established are: (1) An agreement for the sale of land complies with section 2(1) of the Alienation of Land Act 68 of 1981 if it is in writing, signed by the parties, and contains sufficient information to identify the property sold without recourse to extrinsic evidence of the parties' negotiations, even if the description contains an error. (2) Section 2(1) does not require a faultless description of the property couched in meticulously accurate terms. (3) Once a valid agreement complying with section 2(1) has been concluded, the parties are entitled to exercise their common law right to amend or rectify the agreement, including correcting the description of the property, without violating the statutory formalities. (4) A suspensive condition in a sale agreement requiring bond approval by a certain date is fulfilled when the bank approves the loan and furnishes its guarantee within the stipulated timeframe, even if the property was incorrectly described in the original agreement. (5) The subsequent correction of the property description and obtaining of fresh loan approval in respect of the correctly described property does not revive a suspensive condition that has already been fulfilled.
