The executor of the estate of a deceased man (the appellant) brought an application to the High Court for a declaration that the civil marriage to the respondent was bigamous and invalid because of a number of pre-existing customary marriages between the deceased and three other women. The deceased considered the marriages over when the women left him and never returned. The deceased had executed a will and later four codicils. The High Court found that the respondent’s civil law marriage was a lawful marriage in community of property, and the will was declared null and void. The appeal is of the order of the High Court. The Supreme Court heard testimony from one of the wives married to the deceased under customary law and from experts in Swazi law and custom relating to the dissolution of customary marriages. The Supreme Court found in favour of the appellant. The decision of the High Court was set aside and the Master of the High Court was to appoint a suitable and proper person to administer the deceased estate. This case is important as it illustrates the importance and status of Swazi law.
