My daughter's husband is in Jail for Domistic abuse and will be in Jail for a long time... can she get SSI or other assistance (SSI) while he is in jail to care for the children?
There is government assistance available to the indigent. Some counties also have a "victim's fund" to assist the victims of certain types of crimes. Check with your local government agencies.
Look into California Aid to Families with Dependent Children (AFDC).
Best of luck to you.
