Help my friend pay for divorce and custody

I’m just a regular person trying to help out my best friend since neither one of us has much money.  My best friend has been trying to divorce her husband who has been manipulative and verbally abusive for over a year. She frequently gets nasty and awful texts from him about it all.  He often talks bad about her to their kids and causes problems in many areas of her life. He refuses to pay any child support even though my friend has the kids most of the time and he has had a job all year while she hasn’t due to the pandemic. He’s been unwilling to help with the divorce process because he “doesn’t want to fork over money to get dumped.” She’s just trying to divorce him and get full custody of her two young kids and needs some money for a lawyer and other legal fees. She barely has enough money to pay for her and her kids needs, let alone legal fees. Any money would help. She just wants to get her and her kids out of this situation and to move on.
