THE FACTS

Harold John Anderson and Karin Renate Anderson executed a joint will during their marriage. After Karin's death, Harold faced issues with the German authorities regarding the will's validity. He later executed new wills but the applicants sought to enforce the original joint will.

THE ISSUES

Whether the joint will is valid and binding in South Africa despite subsequent wills executed by the surviving spouse.

ANALYSIS

The court found that massing and adiation occurred, which bound the surviving spouse to the terms of the joint will. The joint will was deemed valid under both German and South African law.

REMEDY

The court ordered the Master of the High Court to accept the joint will as the valid testament for Harold's South African estate and appointed executors as nominated by the beneficiaries under the joint will.

LEGAL PRINCIPLES

The principles of massing and adiation in joint wills bind the surviving spouse to the terms of the joint will, preventing them from altering dispositions related to the massed estate after accepting benefits under that will.
