How territories calculate support

Familiar frameworks, local nuance

Most U.S. territories follow income-shares principles, with administrative or judicial discretion shaped by local statute.

Income-shares foundation

Both parents' incomes are combined, an estimated child cost is derived, then each parent contributes proportionally.

Add-on expenses

Healthcare premiums, uninsured medical, and childcare are typically added on top of basic support and split by income share.

Parenting-time impact

Significant overnights with the paying parent reduce the cash transfer because direct care offsets some support.
