You will normally marry in the church where the banns were called or in the office of the District Registrar. However, you can marry somewhere else if this is necessary. Usually there has to be a good reason for this, and the District Registrar or pastor will decide if this is possible. For a custom marriage you must follow the customary practice in deciding where your marriage ceremony will take place. The Ceremony There must be at least two witnesses who are over the age of 21 years at the wedding.
Witnesses are people who can see and hear all of the marriage ceremony.
If the ceremony takes place in secret then it is not a legal marriage. The laws relating to civil and church marriages also apply to custom marriages. In the past custom allowed practices that the law has now made illegal. For example, the law says that a woman cannot marry until she is 16 years old. Women often married in custom at a much younger age.
