There is the office of the public defendant which provides legal services to people who cannot afford to hire an attorney in a legal proceeding. She can also seek support from the various lobby groups, human rights and legal activists.
I am sorry to hear about that. It's always disturbing when families break up. Having said that ... it happens .. parents split up because they just don't love each other anymore .. but chances are, they both still love their children.
If that's the case .. The mother will have to get out and look for work to support her family. There is legal action to be taken to get the father to pay child support. If he is ANY kind of man .. he will not withhold paying to support those children.
Social assistance, unemployment .. I believe both have programs to help under educated people acquire skills so they CAN get jobs.
Do you have any family that can help you at first if not there are agency's out there that can help with section 8 food stamps and other things that you could qualify for good luck your kids need you more than ever don't give up
