Hi abc
Well if that is the only option she is giving you then so be it on her head. It could be the case that she receives less, on their calculations. The biggest problem is with the regularity in which they administor the 'monthly' payments. She may end up being owed money, even though you might have paid the CSA. If you go onto the CSA website you will find their calculator, have a go at that and see how it compares.
Horrible when children are used as weapons.
Good luck abc and keep us posted, I for one would be very insterested to hear how you fair with the CSA.
