When a Alliant member passes away, the Special Services handles the transition of accounts to beneficiaries or the estate. Accounts with Payable on Death designations or trust ownership transfer outside of probate, while solely-owned accounts may require Letters Testamentary or Letters of Administration from the probate court.
Alliant provides an online portal for initiating death claims, which can simplify the initial notification and document submission process. Claims can also be started by phone or by mailing the required documents.
Here is the step-by-step death claim process at Alliant:
Overnight mail address: Alliant Credit Union, Attn: Special Services, 11545 W. Touhy Avenue, Chicago, IL 60666 (phone: 773-462-2182). The Member Guide to Account Settlement PDF provides detailed step-by-step instructions for each account type. For mortgage-related matters, contact Dovenmuehle (DMI) directly at 1-866-341-1017.
Processing timelines at Alliant: Named beneficiaries can receive funds upon providing death certificate and completing the Dispersal Form. Accounts requiring probate depend on court timelines.. Incomplete documentation is the most common cause of delays—submitting all required documents with the initial claim helps avoid additional processing time.
Alliant requires several documents to process a claim, including Certified death certificate, Government-issued ID (driver's license, state ID, or U.S. passport), and Beneficiary Funds Dispersal Form for Deceased Member (provided by Alliant after notification), and additional documentation depending on the account type. Certified copies are typically needed—photocopies are generally not accepted for death certificates or court documents.
No. Per Alliant Credit Union policy, beneficiaries (POD designations) may not be added to checking accounts. Beneficiaries can be added to savings accounts and certificate accounts. To protect checking account funds, consider adding a joint owner with right of survivorship or retitling the account to a trust.
Contact Alliant at 800-328-1935 to notify them of the death. For joint accounts, the surviving owner retains the account. For accounts with named beneficiaries, Alliant will email or mail a Beneficiary Funds Dispersal Form for Deceased Member. Beneficiaries receive funds upon submitting the completed form, death certificate, and government-issued ID. Accounts without beneficiaries require Letters Testamentary or Administration from probate court.
Alliant's Special Services can be reached by phone at 1-800-328-1935 and fax at 1-773-462-2124 for questions throughout the claims process.
If the deceased held multiple Alliant accounts, each may require a separate claim or have different documentation requirements. The Special Services can confirm which accounts require individual attention and which can be processed together.
