I am a father with 2 sons, and they live with me.
I've never asked for any child maintenance as it just felt wrong asking for money from their mother.
Looking back now this seems pretty sexist on my behalf, money is getting a bit tight, I've looked at the CSA website and I could get 20% of her salary to help pay for the children's costs.
If I ask for this it would put her in financial trouble. She'd probably end up living back at her parents house.
So would I be unreasonable to ask for child maintenance?
