Beginning Sunday, April 19, 2026, through 4:30 p.m. Wednesday, April 22, 2026, Sussex County will be transitioning its financial and permitting systems to a secured cloud-based environment. This upgrade will improve reliability, speed, and security, allowing the County to better serve you.

During this period, services will be limited to drop-off transactions, which will be processed once the upgrade is completed. The County will be unable to accept payments, process permits, or issue certificates of occupancy. The Citizen Self Service portal on the County website also will be unavailable during this time.

The County is providing this information in advance so you may plan accordingly, including submitting any building permit requests the week prior to the upgrade.

The County appreciates its customers’ understanding and apologizes for any temporary inconvenience.

The building locks at 4PM daily. Please call the office number below for assistance.

Appointments are required for the following services: opening a probated estate, closing a probated estate, ancillary estates, and depositing a Will for safe-keeping.

To better serve you, appointments are strongly recommended for all other services. Walk-ins are welcome but will be worked around scheduled appointments.

The Register of Wills office is responsible for the efficient administration of all estates being probated in Sussex County. The Register of Wills grants authority to personal representatives to administer estates and is responsible for making sure that those administrations are carried out in compliance with Delaware Law.
