Child Support Past 18 in Alaska: High School Graduation and Age Limits
In Alaska, child support usually ends at 18, the age of majority. A court can extend it for an unmarried 18-year-old still pursuing a high school diploma and living with a parent or guardian, until graduation or the 19th birthday, but the extension has to be in the order.
What is the child support age limit in Alaska?
A person is considered to have arrived at majority at the age of 18 (AS 25.20.010), and a support order usually runs until then. The Alaska Bar Association explains that the obligation typically lasts until the child turns 18, with a possible extension for a child still in high school (Alaska Bar Association).
Does child support stop at 18 in Alaska if the child is still in high school?
It can continue if the order provides for it. The statute lets a court modify a judgment to provide for the care, nurture and education of unmarried 18-year-old children while they are actively pursuing a high school diploma or an equivalent level of technical or vocational training and living as dependents with a parent, guardian or designee (AS 25.24.170(a); AS 25.24.140(a)(3) does the same during a pending case). The agency lists extending support for such a child as a reason to modify an order (agency FAQ).
How long does the Alaska high school extension last?
The Alaska Bar Association describes it as continuing until the child graduates or turns 19, whichever comes first. Because the statute covers 18-year-old children, it cannot run past the 19th birthday. Graduating before 18 does not end support early: the age of majority is still 18.
What date does Alaska child support end? Examples
The usual end date is the 18th birthday, and the high school extension cannot go past the 19th:
| Child born | Support usually ends | Extension cannot pass |
|---|---|---|
| March 15, 2012 | March 15, 2030 | March 15, 2031 |
| August 31, 2010 | August 31, 2028 | August 31, 2029 |
| November 2, 2015 | November 2, 2033 | November 2, 2034 |

What if my order does not mention the extension?
An order that does not already provide for support after 18 may need to be modified to add it, so ask before the child’s 18th birthday. For a court order, only the court can modify it; for an agency order, the agency can (agency FAQ).
Do arrears end when child support ends?
No. Each payment that came due is a judgment that became vested when it was due and unpaid (AS 25.27.225). See the Alaska child support arrears calculator and whether Alaska arrears expire.
How do you confirm your end date, step by step?
- Read the order for an end date or event; it controls.
- Find the 18th birthday in the Alaska child support end date calculator.
- If the child will be 18 and finishing high school, ask for the extension before the birthday.
- Check the balance and arrange any arrears (arrears calculator).
- Ask the court or the agency to end the withholding once support has ended.
