As I understand it, neither South Africa nor Singapore confer citizenship by descent unless an application for registration as a citizen is made and certain other requirements are fulfilled. If neither application has been made, then the child is currently stateless. Although that does not alter the pathway to British citizenship, section 1(3) of the 1981 Act.
Singapore citizenship, in particular, carries a National Service obligation and under current law, usually requires any foreign citizenship to be formally renounced in early adulthood. If the child's future does not lie in Singapore, it may be prudent to consider options before registering as a Singapore citizen, especially if child is also British. Ironically, it may be easier for child to establish residence in Singapore later in life as a foreigner rather than as a former citizen (if child renounces or is deprived of Singapore citizenship). Those in the Singaporean expatriate community will likely have more up to date information on developments in Singapore in this respect.
