Has anyone ever used free / pro-bono legal services related to family law here (low income)?

I have a co-worker who is being destroyed by his STBXW, as well as making a mess of custody matters. The guy is very low income and cannot afford an attorney, so he has been just kind of going with whatever she tells him. At this point he pretty much lost everything and is living week to week and has had zero legal representation. I feel really bad for the guy as he comes in distraught and in tears many mornings. I thought there was a way for low-income people to get legal help, but not sure where to direct him. One place pops up, but under their services it doesn't list family law.

Does anyone have experience or know someone who has with this stuff? I really would love to help the guy out.

Thanks!
