Here is the opinion in M.S. v. O.S. An excerpt:
In this paternity action, O.S. appeals an order requiring him to pay child support for his young twins. He contends the trial court abused its discretion by including in his income for purposes of guideline support twice-yearly bonuses he received from his Indian tribe, and attorney fees the tribe paid on his behalf. We agree with O.S. on the second issue, and reverse the order and remand the matter for further proceedings. Additionally, for the court’s guidance on remand, we hold it may properly include the bonuses in his gross income.
Turtle Talk 
Yes, the court agreed on the one matter with O.S. However, a further read indicates the attorney fees paid by his tribe can be considered income but determined under a different section. Money is Money.
