How your Del-One accounts transfer at death depends on how each one is set up. As a membership-based credit union, Del-One membership is open to employees of the State of Delaware, employees of Del-One Select Employer Groups, immediate family or household members of existing members, and Delaware residents. Residents of adjacent bordering counties in Maryland and Pennsylvania may also be eligible through the Del-One Foundation. Combined network is 16 branches across Delaware (13 Del-One + 4 legacy Louviers) and is part of the Co-Op Network with nearly 30,000 surcharge-free ATMs. Until full systems integration on Operational Day One (August 3, 2026), Del-One members visit Del-One branches and legacy Louviers members visit legacy Louviers branches (Omega, Main Street, Glasgow, Chestnut Run). With 13 account types, the transfer rules vary—getting the right designations in place now prevents delays and court involvement later.
Account holders can update their beneficiary designations at Del-One in branch, by mail, and by phone. Accounts can also be retitled into a trust to keep them out of probate entirely.
Del-One provides specific procedures for both proactive estate planning and filing claims after a death.
