I would like to see a system where the NRP has a minimum amount that they ought to pay towards their child, say £250pm (increases with wages) for everyone regardless of whether they are employed or not.
This amount plus any extra is paid to RP every month from a central fund. A bit like the criminal injuries system.
Then the man, sorry NRP, keeps that debt forever and has to pay it off (like a student loan) back to the central fund. That money will remain due even past child's 18th and will be recovered and paid to the NRP so as to recuperate her for the money she has already spent raising the child.
They should have powers of enforcement like in USA, like passport removal. No payment, no passport and certainly no Visa to a country who won't support the UK in the system of a man paying towards raising his children. Sorry again, i mean NRP!
Removal of goods, like cars, boats etc, so self employed men can't get rid of their cash easily.
It should affect their whole life should they decide not to pay. Obviously the ones who can't pay yet can keep the accrued debt until they can.
Even repossessing their houses as that is an asset.
Then prison, without the debt being written off.
There should be a register of fathers who won't pay available on request, (bit like DA) to see if your new man is socially responsible towards his offspring.
There should be punishment via courts for refusal to pay and reported in local papers, to publicly shame them.
Hopefully that way as least the very poorest would have access to the money regularly and without the mother, sorry RP, having to hope and pray the child's father will deign to throw some pennies over this week.
If the public starting seeing this as something that is socially unacceptable then society would start to view it differently. Basically people think it's wrong to drink drive and maim someone, so that required prison, settlements etc. They need to see the deliberate withholding of monies to raise a child as slow drip, long term abuse of that child.
Oh yeah and a man SHOULD NOT pay less for his own child/ren if he's living with some other man's child. Who the hell thought that one up?
