The South Africa Children's Act of 2005 (which came fully into force in 2010) enabled the "commissioning parents" and the surrogate to have their surrogacy agreement validated by the High Court even before fertilization. This allows the commissioning parents to be recognized as legal parents from the outset of the process and helps prevent uncertainty - although if the surrogate mother is the genetic mother she has until 60 days after the birth of the child to change her mind. The law permits single people and gay couples to be commissioning parents. However, only those domiciled in South Africa benefit from the protection of the law, no non-validated agreements will be enforced, and agreements must be altruistic rather than commercial. If there is only one commissioning parent, s/he must be genetically related to the child. If there are two, they must both be genetically related to the child unless that is physically impossible due to infertility or sex (as in the case of a same sex couple). The Commissioning parent or parents must be physically unable to birth a child independently. The surrogate mother must have had at least one pregnancy and viable delivery and have at least one living child. The surrogate mother has the right to unilaterally terminate the pregnancy, but she must consult with and inform the commissioning parents, and if she is terminating for a non-medical reason, may be obliged to refund any medical reimbursements she had received.
