Ex will do anything not to support his kids

I have 3 kids off my ex.at first he tried to say the kids werent his ,so he didnt have to take responsibility.blood test that the csa asked for proved otherwise.

Then he started working less hours at work ,to minimize the payment of child support.

Then still not happy with paying fourtythree pound per week for three kids ,he opted for voluntary redundancy,faked depression and is now claiming sickness benefit ,just to get out of paying for his 3 kids,which hes never bothered to see.

What a lovely waste of space he really is.
