Or is that just my experience?
My ex husband paid maintenance after we split at the rate suggested by his solicitor. One day he suddenly stopped because he wanted to pay his credit cards off and he also felt he was paying too much. I contacted the CSA (at the time) and he ignored them and ended up doing a deduction of earnings order. And they figured out that he owed more not less. A few years later he had a big pay rise, did not tell them so he managed to under pay me for years.
Now, my baby's dad who I don't live with had said to me before she was born that he'd use the government website to work it out & I said fine.
Then about 2 months ago he suddenly decided to halve it, apparently because he didn't get any commission that month. I've never seen his payslips so I've trusted him to be honest.
I suggested we ask the CMS to calculate it because that's fair and he hit the roof. Has been absolutely vile to me in messages and has now blocked me.
He has not lost his job or been furloughed had recently decided to buy our daughter a £500 number plate for her car which I argued she doesn't actually need right now but she does need clothes and formula etc!
