Does Ketchikan have its own rule?
No. Alaska Civil Rule 90.3 applies across Alaska, so a case from Ketchikan is decided by the same numbers as one filed anywhere else in the state. What changes locally is the courthouse, the clerk's procedure and how long the docket takes — not the amount.
What the statute says
Alaska Civil Rule 90.3 — Alaska child support (Civil Rule 90.3, primary custody). Rule 90.3 applies 20% for one child, 27% for two, 33% for three, plus 3% for each additional child, to adjusted annual income — capped at $138,000 a year ($11,500/month). This is the primary-custody formula; shared custody (each parent 30%+ of overnights) uses a different calculation.
