Well - I think Mud's got the right idea.
The specific gap in help, support & resources is of a legal nature.
And knowing WHEN one needs to try to do what, to protect oneself. No one wants to feel like they're "crying wolf" to authorities and because of the he said/she said nature of most of the legal disagreements (and risk of having one's story discounted & minimized) and the subjective nature of what constitutes danger to any specific judge and the terror of not being believed...
... I think a lot of people wait too long to start documenting things, building evidence, reporting problems - taking action. Just like there are now tables of "symptoms" for teachers to recognize the signs of child neglect & abuse... maybe it would help some people recognize earlier, that they are in a situation where they need help and to start taking appropriate actions to protect themselves, legally too.
I'm seeing "building a file of evidence" as being an often overlooked tool to help people later - even in the area of being believed. I wish I knew what kind of evidence.
Mud?
