What Is a State Disbursement Unit
A State Disbursement Unit (SDU) is a centralized processing center operated by each state that receives, records, and distributes child support payments. Every state maintains its own SDU, which acts as the middleman between the paying parent (obligor) and the receiving parent (obligee). When you have a child support order, payments go to your state's SDU first, then the SDU forwards the funds to you, typically within 1 to 2 business days.
The SDU handles both wage withholding payments from employers and voluntary payments made directly by the paying parent. It also maintains detailed payment records that become critical evidence if disputes arise about whether support was paid on time or in full. Your state's SDU is separate from the court that issued your support order, though they work together to enforce compliance.
How State Disbursement Units Work
Your state's SDU processes child support through a specific workflow:
- Wage withholding: When an income withholding order is issued, employers send the support payment directly to the SDU. The SDU records the payment, deducts any applicable fees (usually $1 to $2 per transaction in most states), and deposits the remainder to your account within 1 to 2 business days.
- Direct payments: The paying parent can mail checks or make electronic transfers directly to the SDU. These payments are recorded and distributed on the same timeline as wage-withheld amounts.
- Record keeping: The SDU maintains a permanent electronic record of all payments, including dates, amounts, and any arrears (unpaid balances). These records are admissible in court and form the basis for enforcement actions if payments fall behind.
- Fee collection: Most states charge a small administrative fee per transaction, typically $0.50 to $2.00, which is deducted from the payment. Some states waive fees for certain low-income obligors or waive the first payment.
- Interstate cases: If the paying parent lives in a different state, the case may involve two SDUs. The obligor's state SDU receives payment and forwards it to the obligee's state SDU, adding a 2 to 4 day delay.
Why the SDU Matters in Your Divorce
The SDU directly affects how you receive support and how arrears are tracked. If you're the receiving parent, the SDU's records become your proof of payment history if you ever need to enforce the order or if the paying parent claims they've paid in full when they haven't. If you're the paying parent, understanding how the SDU processes payments helps you avoid missed or late payments that trigger enforcement actions.
The SDU also plays a role in spousal support in some states. While most states direct spousal support through the court system, a few states route it through the SDU if it's combined with child support. Check your state's specific rules, as this varies significantly by jurisdiction.
If your child support order includes income withholding, the SDU is where that withholding happens. The court doesn't collect the money directly. Employers send it to the SDU, and you receive your portion through the SDU's distribution system.
Accessing Your SDU Account
Most states provide an online portal where you can view your payment history, current balance, and any arrears. Log in with your case number and PIN, which the court provides when your support order is entered. You can typically access this portal 24 hours a day to check payment status and download payment records for your records.
If you need to update your banking information, address, or report a problem with a payment, contact your state's SDU directly. Phone numbers and online portals are available through your state's child support enforcement agency website.
Common Questions
- How long does it take to receive a payment through the SDU? In-state payments typically arrive within 1 to 2 business days. Interstate payments (where the obligor lives in a different state) take 2 to 4 business days longer because the money must be transferred between two state SDUs. Weekends and holidays extend these timelines.
- What happens if I don't receive a payment the SDU says it sent? Contact your state's SDU immediately with your case number. Provide the payment date shown in your online account. The SDU can verify whether the payment reached your designated bank account or address. If there's a delay or error, the SDU can investigate and reissue the payment.
- Can I choose how to receive payments from the SDU? Most states offer direct deposit to a bank account (fastest option), paper check mailed to your address, or a prepaid debit card issued by the SDU. Direct deposit is the most reliable and fastest method. Set it up through your SDU's online portal or by contacting the agency directly.
