A single mother has sued a local public security department because authorities have refused to provide hukou, or household registration, for her out-of-wedlock child in Dongguan, Guangdong province.

The 39-year-old mother, surnamed Fang, is demanding that the Dongcheng district branch of the Dongguan bureau of public security immediately allow her child to register hukou under the law.

Fang went to court, with the help of local public welfare organizations, on Tuesday.
