Tell the operator at CSA that domestic violence was involved & they will agree to chase it up for you. I remember being asked something about did I feel safe asking him for money or something along those lines.

The amount you will get depends on what you earn, what he earns & if he has other children. I only receive $20 a week (well I would if he paid) for my son because my ex already had a daughter from a previous relationship & I also have my own income. Completely unfair in my view, but that's how it works.
