The short answer
No, they may not refuse to register a child’s birth. Here's why.
The whole question
I have a 3-month-old child with a foreign national woman whose visa expired more than 12 months ago. Our child was born in South Africa but is not registered because the Department of Home Affairs refused to do so based on the mother's expired visa. Is a valid visa a determining factor for registering a child?
The long answer
Thank you for your email asking if your child’s mother’s expired visa is grounds for DHA to refuse to register your child.
No, DHA may not refuse to register a child’s birth on the grounds of the legal status of its parents.
In August 2018, the High Court in Grahamstown found that the Births and Deaths Registration Act did not stipulate which parent had the duty to register the birth. The court found that requiring an immigrant parent to produce a valid visa or permit for the registration of the birth of a child, did prevent a father from registering the birth of his child, and this was not what the law intended.
The court found that the father had the right to register his child’s birth, when the mother of the child was either absent, or whose visa had expired, making her an illegal immigrant. The Act also did not prevent an unmarried father from registering his child’s birth.
