To confirm, I have them 40% of the time during the week to include 2 nights, it should be 3 or 4 on alternative weeks, and no good reason not to,
As other posters have pointed out you pay the childcare provider with the vouchers on the days you have them.
My DD was one of the last to get on the voucher scheme via her father, my DP.
He decides and then authorises the amount that each provider gets from the childcare vouchers. So the money used to go to her CM to pay part of her fees, now it goes on holiday clubs.
So if you have them on Tuesday night one week and not the other. You authorise 2 days of childcare voucher payments every other week.
so I guess I'll just have to go the legal route as I also have pretty much the same costs as her and get zero money from her toward the children and the expectation that I then fund all extra-curricular activities. The childcare vouchers have been paid on top of the maintenance which I pay her.
There is no legal route for you to go down.
