The hearing

- Documents and witnesses
- Bring three copies of each document you want in the record (for you, the employer and the Referee). Signed statements generally cannot be used unless the person who signed comes to testify; ask witnesses with first-hand knowledge to attend.
- Subpoena
- Contact the Lower Authority Appeals Unit at least ten days before your hearing to ask for subpoenas.
- Interpreter
- Contact the Lower Authority Appeals Unit at least ten days before your hearing if you need an interpreter or have other special needs.

Overpayments and waivers
If it is finally decided that you got benefits you were not entitled to, you must repay them, even if the overpayment was the Division's mistake. For overpayments without fraud, the Division may take up to 50% of later weekly benefits and may not charge interest. If the Division finds fraud, you must repay with interest plus a 15% penalty, you are disqualified for 1 year, and you cannot get benefits again until the fraud overpayment, penalty and interest are paid in full.
- Appeal within
- 15 days from the mailing date of the notice of overpayment and order for recoupment
- Fraud penalty
- 15% added when the overpayment is fraud
- Waiver
- The state can waive some overpayments.
- The standard
- The Division may waive repayment of an overpayment that was not caused by fraud if repayment would be against equity and good conscience, or if the overpayment was the result of Department error. Repayment can be found against equity and good conscience if, when you apply, you are getting benefits from a low-income public assistance program the Department designates.
- How to ask
- The Division notifies you in writing that you can apply for a waiver. You have 30 days from the date of that notice to send a completed waiver application. If the waiver is denied, you can appeal to an Appeals Referee within 15 days.
- How the state collects
- The Division can take overpayments from future benefits, sue in court, and take state and federal tax refunds (the federal refund only for an overpayment caused by fraud or unreported earnings, after a notice giving you at least 60 days to respond). It may write off an uncollectible non-fraud debt after 3 years and cannot start collecting a non-fraud overpayment more than 5 years after the benefit year ends unless it has sued.
Law: 19 Del. C. sec. 3325; 19 Del. C. sec. 3325(h)
What federal law adds on overpayments
- Whether an overpayment can be waived, and how to ask, depends on your state's law. See your state's page.
- Your federal tax refund can be taken to pay a past-due state unemployment overpayment caused by fraud or by not reporting your earnings, once it is final under state law. Before this happens, the state must notify you and give you at least 60 days to show that the debt is not owed or not legally enforceable.
Law: 26 U.S.C. 6402(f)
- For fraud overpayments, the state must add a penalty of at least 15 percent.
Law: 42 U.S.C. 503(a)(11)
