How to designate beneficiaries at Sentinel Group

Beneficiaries are managed online

Beneficiary designations on Sentinel Group retirement retirement accounts carry more weight than most people realize. They override a will, control who receives the balance, and determine the tax treatment of inherited distributions. Reviewing these designations after any major life change is essential.

Each of Sentinel Group's 6 retirement accounts has different rules for how it transfers at death. The sections below explain the options for each.
