How to Appeal an Unemployment Denial in Delaware
Reviewed by DocDraft Legal Team · Delaware · Last updated 2026-09-06
An unemployment appeal is the formal request you file to challenge a decision that denied, reduced, or ended your unemployment benefits, asking a neutral referee to review the agency's ruling. In Delaware, the Department of Labor's Division of Unemployment Insurance decides eligibility, and a Claims Deputy issues that decision as a determination. You appeal in writing within 15 calendar days of the date the determination was mailed, and an Appeals Referee sitting as an Appeal Tribunal holds a hearing (19 Del. C. section 3318). If the referee rules against you, you can appeal again to the Unemployment Insurance Appeal Board within 15 days (section 3320). The deadline is fixed with no general good-cause extension, so file as soon as possible, and keep filing your weekly claims while the appeal is pending.

You have 15 calendar days from the date the Division of Unemployment Insurance mailed your Claims Deputy determination (19 Del. C. section 3318). The clock runs from the mailing date, not the day you opened it, so file as soon as possible. Missing the deadline can make the determination final.
Where do I file an unemployment appeal in Delaware?
Send your written appeal to the Division of Unemployment Insurance Appeals Unit, PO Box 9950, Wilmington, DE 19809-0951, or email it to DOL_DUI_APPEALS_REQUEST@delaware.gov. You can also file in writing or in person at your local unemployment insurance office. Include your full name, contact information, and case number so staff can match it.
Can I keep getting benefits while an appeal is pending in Delaware?
Keep filing your weekly claims while the appeal is pending. Delaware pays benefits only for weeks you properly claimed and were otherwise eligible, so a gap in weekly filing can cost you back payments even if you win. Filing weekly does not guarantee payment, but it protects weeks the referee may later approve.
Delaware unemployment appeal law at a glance
In Delaware, the Department of Labor's Division of Unemployment Insurance decides eligibility, and a Claims Deputy issues the determination a claimant can challenge. A claimant who disagrees files a written appeal within 15 calendar days of the date the determination was mailed (19 Del. C. section 3318). The first-level appeal goes to an Appeal Tribunal, where an Appeals Referee holds a hearing and then affirms, modifies, or reverses the Claims Deputy. If the referee rules against you, a second-level appeal goes to the Unemployment Insurance Appeal Board within 15 days under section 3320. The statute sets a fixed deadline with no general good-cause extension, so file promptly. Delaware instructs claimants to keep filing weekly claims while the appeal is pending, because benefits are only possible for weeks properly claimed and otherwise eligible.
Appealing a Delaware unemployment denial after a quit-versus-fired dispute
Suppose the Division of Unemployment Insurance mails you a Claims Deputy determination denying benefits because it treated your job separation as a voluntary quit. You disagree, believing you were let go. Because the mailing date controls the timeline, you note that date and file a written appeal within 15 calendar days, explaining that your separation was an involuntary layoff, with your final pay stub and a supervisor email attached. You keep filing weekly claims while you wait. At the hearing, an Appeals Referee reviews the evidence and questions both sides. If the referee still rules against you, you file a second-level appeal to the Unemployment Insurance Appeal Board within 15 days. Attorney review of your appeal statement is available through DocDraft.

Suggested Compliance Checklist
Find the mailing date on your Claims Deputy determination
The day you receive the determination days after startingLocate the mailing date printed on your Division of Unemployment Insurance determination. That date starts the 15-day appeal window under 19 Del. C. section 3318, so calendar it immediately and count forward from it, because the clock does not wait until you open the envelope.
Read the reason Delaware gave for the decision
As soon as you receive the determination days after startingIdentify the exact eligibility issue the Claims Deputy relied on, such as a quit-versus-fired dispute, availability, or an overpayment. Your appeal is stronger when it responds directly to that finding rather than restating your situation generally.
Write your appeal with the required details
Within 15 days of the determination mailing date days after startingWrite a signed appeal with your full name, contact information, case number, the decision you are appealing, and why it is wrong. Attach supporting pay records or statements. Attorney review of your appeal statement is available through DocDraft.
File the appeal within 15 days
By the 15th day after the determination mailing date days after startingSubmit the appeal by mail to the Division of Unemployment Insurance Appeals Unit, by email to DOL_DUI_APPEALS_REQUEST@delaware.gov, or in person at your local office before the 15-day deadline. Keep a dated copy and proof of sending in case the timing is questioned.
Keep filing your weekly claims
Every week while the appeal is pending days after startingContinue filing your weekly claims during the appeal. Delaware can only pay weeks you properly claimed and were otherwise eligible, so unbroken weekly filing protects back payments if the Appeals Referee rules in your favor.
Prepare for the Appeals Referee hearing
Before the hearing date on your notice days after startingGather documents and witnesses, review the determination and the record, and organize the facts that support your position. The Appeal Tribunal mails a hearing notice with the date and format. Attending is critical, because missing it can lead to a decision against you.

Frequently Asked Questions
An unemployment appeal is your formal, written request asking a neutral Appeals Referee to review a Division of Unemployment Insurance decision that denied, reduced, or ended your benefits. In Delaware it is filed against the Claims Deputy determination, and it triggers a hearing before an Appeal Tribunal under 19 Del. C. section 3318.
The determination is the Division of Unemployment Insurance's initial decision on your eligibility, issued by a Claims Deputy. An appeal is the separate step where you challenge that decision before an Appeals Referee who is independent of the Claims Deputy. The determination comes first; the appeal is how you contest it within 15 days.
You have 15 calendar days from the date the Claims Deputy determination was mailed to file a written appeal (19 Del. C. section 3318). The clock runs from the mailing date, not the day you opened the envelope. The deadline is fixed, so file as soon as you can.
If you do not appeal within 15 calendar days, 19 Del. C. section 3318 says the Claims Deputy determination becomes final and benefits are paid or denied accordingly. Delaware sets no general good-cause extension, so file on time. The Appeal Board can review a decision on its own motion only in limited situations.
An Appeals Referee sitting as an Appeal Tribunal decides the first-level appeal, independent of the Claims Deputy who issued the determination. The referee holds a hearing, reviews the record and your evidence, questions both sides, and then issues a written decision that affirms, modifies, or reverses the determination under 19 Del. C. section 3318.
The Appeal Tribunal mails a hearing notice, and the hearing is usually held by phone or in person. The Appeals Referee takes testimony under oath from you and from the Division or your former employer, reviews documents, and lets each side ask questions. A written decision follows explaining the result and further appeal rights.
Yes. If the Appeals Referee rules against you, you can file a second-level appeal to the Unemployment Insurance Appeal Board within 15 days of that decision (19 Del. C. section 3318 and section 3320). The Board reviews the hearing record rather than holding a new hearing, so present all your evidence at the referee stage.
Yes. Delaware instructs claimants to keep filing weekly claims while an appeal is pending, because you can only be paid for weeks you properly claimed and otherwise met eligibility rules. Filing weekly does not guarantee payment, but skipping it can permanently forfeit weeks the Appeals Referee might later approve in your favor.
