It is a contract signed before a marriage is solemnized (formally entered into), but can be concluded after marriage, at a substantial cost. For the purposes of this summary we will focus solely on contracts entered into before marriage.
If you own a million rand house before you are married, that house becomes the property of the joint estate once you are married – it belongs to both of you. Similarly, if you owe a million rand on the house, you are both liable for that debt once you are married.
This is the default setting – a marriage in community of property. However, signing an antenuptial contract gives you the option of keeping your estates separate, whilst enjoying the fruits of marriage. Thus that one million rand debt can be managed in such a way that, legally, it does not affect the whole household. The antenuptial contract allows you and your spouse to plan your future knowing that you are insulated should, either of you, for example, lose your job, not succeed in business or run into any other financial difficulty.
