How to open a case

Apply to CSED through its Client Portal. CSED can set up an administrative support order if there is no court order, or enforce a court order. Families on TANF or with children in state custody get services automatically. You can also ask the court for support in a divorce, custody or paternity case; each parent files a Child Support Guidelines Affidavit (DR-305).

Source: one application per case

Yearly fee

$35 a year on cases where the family never received cash assistance, once the custodial parent has received $550 in the federal fiscal year (October-September). In Alaska the fee is charged to the custodial parent and taken from a support payment; the paying parent still gets full credit.

Forms
Paternity (legal fatherhood)

Parents can sign a paternity affidavit at the hospital or birthing center, or get the form from Alaska Health Analytics & Vital Records. If the father is not sure, CSED or a court can order genetic (cheek-swab) testing; when CSED orders the test, the State pays first and the man found to be the father may be asked to repay.

Model
Percentage of income
How it works

When one parent has the children at least 70% of the year, the other parent pays a fixed percentage of his or her adjusted annual income (income after taxes and other mandatory deductions). Shared, divided and hybrid custody use both parents' incomes and separate court forms.

Percentages

1 child 20%, 2 children 27%, 3 children 33%, plus 3% for each additional child (primary custody). The percentages apply to adjusted income up to $138,000 a year; above that the court may add more if just and proper.

Low income

Minimum order is $50 a month ($600 a year), with some exceptions. If your total annual income is $30,000 or less, your adjusted income is the lower of the normal calculation or your total income minus $7,500.

Law: Civil Rule 90.3(a)(5), (c)(3)

Official calculator
Official Alaska child support calculator
Health insurance and medical costs

Every order must include medical support. Health insurance is required if either parent can get it at a reasonable cost; Indian Health Service eligibility is considered. Insurance costs and uncovered health expenses are split equally unless there is good cause, and a parent must repay the other's share within 30 days of getting the bill.

Law: Alaska R. Civ. P. 90.3 (last amended by SCO 2004, effective October 16, 2023)

Change a child support order in Alaska

When a change is allowed

A material change of circumstances is presumed if support figured under Rule 90.3 today is more than 15% higher or lower than the current order. A change in custody that changes the formula also counts. An order not changed in the last 3 years can be reviewed without showing a change. Past-due support cannot be changed retroactively; a new amount starts only after the motion or CSED notice is served.

How to ask

Court orders: file a Motion to Modify in court (filing fee $75, or ask for a fee waiver; free if both parents agree and file an uncontested motion). Administrative orders made by CSED: ask CSED by phone, email or letter and send your last two tax returns, W-2s, three months of pay stubs and proof of health insurance. CSED does not change court orders.

Can I ask for a change? Check your situation

Alaska's rule: A material change of circumstances is presumed if support figured under Rule 90.3 today is more than 15% higher or lower than the current order. A change in custody that changes the formula also counts. An order not changed in the last 3 years can be reviewed without showing a change.

Law: Alaska R. Civ. P. 90.3(h); AS 25.24.170(b)

Until a new order is made, the current amount is still owed. A change can count only from the date the other parent gets notice of your request, so ask soon.

Law: 42 U.S.C. 666(a)(9)

How to ask in Alaska: Court orders: file a Motion to Modify in court (filing fee $75, or ask for a fee waiver; free if both parents agree and file an uncontested motion). Administrative orders made by CSED: ask CSED by phone, email or letter and send your last two tax returns, W-2s, three months of pay stubs and proof of health insurance. CSED does not change court orders.

Ask the agency to review (change) your order

Collect unpaid child support in Alaska

Arrears means support that is past due. The child support agency can use these tools to collect it:

Collection tools
  • Income withholding from wages, unemployment and other benefits
  • Taking all or part of the Permanent Fund Dividend (PFD)
  • Federal tax refund offset
  • Liens on property and bank accounts
  • Driver's and occupational license action
  • Credit bureau reporting
License suspension

CSED says a case qualifies for license action when arrears reach four times the monthly support amount, or $1,000 or more with no payment in 60 days. By statute, you are on the list if you owe more than four times your monthly support. You first get a 60-day notice; a driver's license is then suspended after a 150-day notice unless you get a release, for example by signing a payment agreement.

Law: AS 25.27.244, 25.27.246

Interest on unpaid support

Interest on past-due support is charged at 6% a year (or a lower federal maximum), after notice, when payments are 10 or more days late. No interest is charged on a late current payment if support is being withheld from your wages, unemployment or workers' compensation.

Law: AS 25.27.020(a)(2)(B), 25.27.025

  • Tax refunds. The federal government can take a federal tax refund to pay past-due child support. Law: 42 U.S.C. 664
