A Single-parent family means either a mother-and-child family or father-and-child family. Under the Single-parent Family Support Act, the Child (generally younger than age 18 or younger than age 22 if enrolled in school) support program is provided to the extent to which it is not duplicated with other social welfare benefits under other laws such as the National Basic Living Security Act to the mother or father who lost their spouse due to divorce, death, or going missing without verification of life or death, or whose spouse cannot work for a long time due to mental or physical disabilities.

Single-parent families are entitled to welfare benefits in the amount corresponding to the base median income, family income, and the wealth level of the beneficiary. In addition, Single-parent families are entitled to other additional support programs such as welfare loans for accelerating self-support, first priority right to buy or rent a certain assigned portion of national housing, and accommodations at Single-parent Family supporting facilities.
