No true. You may have to pay child support anyway.
If one parent makes considerably more than the other parent (parent #1 makes $8/hour and parent #2 makes $25/hour then the judge may order parent #2 to pay parent #1 child support.
The court will look at the "best interests" of the children. Courts consider the welfare of the kids.
In a true 50/50 possession, some judges look at what parent #1 would pay and at what parent #2 would pay for child support. If there is a difference, that is the amount of money ordered for one parent to pay to the other parent.
So if you are a multi-millionaire and the other parent makes minimum wage, even if you have the children more than 50% of the time, you could be ordered by a judge to pay child support.
It depends on the judge and the facts of YOUR case.
Talk to an experienced family law attorney in your county about what the judge might do in YOUR case.
