To start, call Sentinel Benefits at (781) 914-1200. Have the account holder's full name, account numbers, and a certified death certificate ready before you call.
Death claim process
Here is the step-by-step death claim process at Sentinel Benefits:
Filing a claim

Notify Sentinel Benefits & Financial Group of the participant's death:
- The plan sponsor (employer) should contact Sentinel at (888) 762-6088 or (781) 914-1200
- Beneficiaries can also contact the Service Center directly at (888) 762-6088
2
Submit a certified copy of the death certificate
3
Establish identity and beneficiary status:
- Provide government-issued photo ID
- Provide documentation confirming beneficiary designation (plan records will be referenced)
- If no beneficiary designation is on file, the plan document's default beneficiary provisions apply (typically the surviving spouse, then the estate)
4
Choose a distribution option based on plan type and beneficiary status:
- Lump-sum distribution
- Rollover to an inherited IRA (for eligible designated beneficiaries of defined contribution plans)
- Annuity payments (for defined benefit and cash balance plans, per plan terms)
- Under the SECURE Act, most non-spouse beneficiaries must distribute the entire defined contribution account within 10 years of the participant's death

Claims Contact
What to know at this institution
Under the SECURE Act of 2019, most non-spouse beneficiaries of defined contribution plans must distribute the entire inherited account within 10 years of the participant's death. Eligible designated beneficiaries (surviving spouse, minor children of the participant, disabled or chronically ill individuals, and beneficiaries not more than 10 years younger than the participant) may qualify for longer distribution periods. The plan sponsor (employer) is typically the first point of contact and can facilitate communication with Sentinel. For defined benefit plans, survivor benefit options are governed by plan terms and may include qualified joint and survivor annuity (QJSA) or qualified pre-retirement survivor annuity (QPSA) provisions.
Processing timelines at Sentinel Benefits: Varies by plan type; typically 2-6 weeks after all required documentation is received and verified. Defined benefit plan claims may take longer due to actuarial calculations. Incomplete documentation is the most common cause of delays—submitting all required documents with the initial claim helps avoid additional processing time.
Sentinel Benefits requires several documents to process a claim, including Certified copy of the death certificate, Government-issued photo ID for the beneficiary or authorized representative, and Completed distribution request form (provided by Sentinel), and additional documentation depending on the account type. Certified copies are typically needed—photocopies are generally not accepted for death certificates or court documents.
Frequently asked questions
Yes, a trust can be named as the primary or contingent beneficiary of a TotalChoice 401(k) or 403(b) plan administered by Sentinel Benefits. However, the 401(k) or 403(b) account itself cannot be retitled into a trust — assets transfer to the trust only upon the participant's death. Under the SECURE Act, a trust named as beneficiary may be required to distribute the entire account within 10 years of the participant's death unless the trust qualifies as a "see-through" conduit or accumulation trust with eligible designated beneficiaries. Consult a tax advisor before naming a trust as beneficiary. If married, spousal consent (written and notarized) is required to name a trust as primary beneficiary for ERISA-governed plans.
If no beneficiary designation is on file at the time of a participant's death, the plan document's default beneficiary provisions govern. For most ERISA-qualified plans administered by Sentinel, the default hierarchy is typically the surviving spouse first, then the estate. In either case, the plan sponsor (your employer) is the first point of contact and will work with Sentinel's Service Center at (888) 762-6088 to initiate the distribution process. An estate receiving plan assets may be required to provide Letters Testamentary or Letters of Administration.
Under the SECURE Act of 2019, most non-spouse beneficiaries who inherit a defined contribution plan account (such as a TotalChoice 401(k) or 403(b)) must distribute the entire account within 10 years of the participant's death. Eligible designated beneficiaries — including surviving spouses, minor children of the participant (until reaching the age of majority), disabled or chronically ill individuals, and beneficiaries not more than 10 years younger than the participant — qualify for longer distribution periods. Surviving spouses may also elect to treat the account as their own or roll it over to an IRA. For defined benefit and cash balance plans, survivor benefits follow plan terms and may include annuity options.
Nonqualified deferred compensation and executive benefit plans administered by Sentinel are not subject to ERISA's spousal consent requirements in the same way as qualified plans. Beneficiary designation rules are governed by the individual plan document, which may permit participants to freely name any person, trust, or entity as beneficiary. However, these plans are also subject to IRC Section 409A rules governing timing of distributions, which can affect how and when a beneficiary receives assets upon the participant's death. Employers and plan participants should review the plan document and consult a tax advisor.
Sentinel Benefits's Sentinel Service Center can be reached by phone at (888) 762-6088 and fax at (781) 213-6770 for questions throughout the claims process.
Multiple Sentinel Benefits retirement accounts may mean multiple claims. Some account types can be processed together, but others require their own documentation. Check with the Sentinel Service Center to confirm what applies.
