With 13 products relevant to estate planning, Sentinel Security Life policyholders need to understand how beneficiary designations control where proceeds go. These designations override a will, so the names on file with Sentinel Security Life are what determine who receives the death benefit.
Beneficiary changes at Sentinel Security Life can be made by mail and by phone. Accounts can also be linked to trusts through beneficiary designations to keep them out of probate entirely.
Sentinel Security Life has documented procedures for both preparing accounts during your lifetime and handling claims when an account holder passes away.
