Support is supposed to be based on the last three years income but if your last year was your best that,s what you will pay on.
There is no law in family law, the only interest the courts have in our children is who pays for them and who can they make pay with the least amount of effort and as much as possible.
Equalization is simple math untill you find out if your name is the only one on the credit card it becomes your side of the debt.
Now that,s not equalization to me but this is less effort and more pay against the payer, all in the good name of, IN THE BEST INTEREST OF THE CHILDREN.
