What to do when a Sentinel Group account holder dies

Report the death to Sentinel Group at 1-888-762-6088

After an account holder at Sentinel Group dies, accounts with beneficiary designations or trust ownership transfer to the designated recipients without probate. Solely-owned accounts require the estate's representative to contact Sentinel Group with the proper legal authority documents.

To start, call Sentinel Group. Have the account holder's full name, account numbers, and the death certificate ready before you call.

Death claim process

Here is the step-by-step death claim process at Sentinel Group:

Filing a claim

1
Call the Sentinel Service Center at (888) 762-6088 (Monday through Friday, 8 a.m. to 7 p.m. ET, excluding holidays) to report the participant's death and ask what the plan requires from a beneficiary.
2
Contact the decedent's employer, which sponsors the plan. Sentinel states: "We send all distribution requests for approval – this action is typically completed by your Employer".
