How to prepare for a divorce without having financial resources?

I am asking this question, after reading another Q, and I figured that there are probably lots of people, mostly women I’m guessing, that need or want to exit a bad marriage, but have little or no access to financial resources, and who may also not have many (or any) family or friends to rely upon for help.

I am not married, nor am I knowelegable about marriage law, so I was hoping that some of you have experience with this subject, or can point us in the right direction to find some answers, and hopefully some assistance, for those who might need it.

I’m asking this in General because I am truly looking for answers that can possibly help someone, rather than suggestions on “what should have been done” to avoid this unfortunate situation. Maybe someone would like to ask another Q in Social about avoiding marital pitfalls.
