You Gal, surely use your CS monies on your children, but some DON'T. For some you would be equalizing incomes to each household, but you can't force the other household to USE that $$$ on the child(ren).
Yes you can. The gov. can force people to pay income taxes and file tax returns. They can easily force people to produce financials to show how CS is being spent.
50/50 custody. 50/50 split of household incomes. You produce financials to prove it. You jerk around, you go to jail, lose custody of your kids and 50% of your income.
THey don't screw around with DUI's. You get caught, you go to jail, you lose your license, you pay fines, etc... You cheat on your taxes, you go to jail, you pay fines. But then people act like parenting time and CS can't be enforced. It can be.
The Gov cannot give anything to anyone - that they have not first taken away from someone else.
