The institution of marriage makes women vulnerable, as does being unmarried in a society that idealises marriage as the norm. It is argued that the use of civil unions as an alternative to legal marriage does not protect women from this vulnerability, and nor do proposed reforms to the institution. The institution of legal marriage therefore must be abolished. A hybrid of Clare Chambers’ piecemeal regulation of relationships and Elizabeth Brake’s minimal marriage, termed the anti-vulnerability approach to relationship regulation (or (...) the AVA) is put forward as the best means to regulate relationships in a way that will protect women from vulnerability. The AVA is implementable in countries where Western marriage is not always the norm, such as South Africa, and is also strongly compatible with LGBTQIA+ relationship styles and arguments against marriage. However, as a piecemeal regulation of relationships cannot be implemented alongside holistic regulation systems, such as legal marriage, legal marriage would need to be abolished to create a system of regulating relationships that will be able to protect women from vulnerability.
