MassMutual is a insurance company with 17 products relevant to estate planning. Life insurance and annuity proceeds transfer directly to named beneficiaries outside of probate, making beneficiary designations one of the most important estate planning steps for MassMutual policyholders.

Managing beneficiaries at MassMutual is straightforward—changes can be made online, in branch, by mail, and by phone, typically taking 10-15 minutes online; 15-20 minutes by mail. Trust funding is also available, allowing families to name a trust as the policy beneficiary or establish an irrevocable life insurance trust (ILIT).

MassMutual has documented procedures for both preparing accounts during your lifetime and handling claims when an account holder passes away.

For questions about any of these procedures, contact MassMutual's Claims Department at 1-800-272-2216. Email inquiries can be sent to lifefax@MassMutual.com.


Frequently asked questions

Four things that catch people out on the FR2265-US. First, MASSACHUSETTS: if the policy owner resides in Massachusetts, a disinterested witness (anyone other than the owner, insured, or beneficiary) age 18 or older must sign the form, and all signature dates must match. Second, DIVORCE: if the policy is subject to a divorce obligation, the former spouse must also sign. If the former spouse will not sign, MassMutual requires the divorce settlement agreement — the first page, any pages about the policy or life insurance, and the signature page — and where that agreement requires a specific beneficiary designation, MassMutual follows the agreement and not the form you submitted, regardless of signatures. Third, THE 6-MONTH CLOCK: a signed form received more than 6 months after its signature date is Not In Good Order, so a form completed and then filed in a drawer has to be redone. Fourth, MINORS: if a minor is named with no UTMA/UGMA custodian designated on the form, money payable to that minor is paid to the court-appointed guardian of the minor's estate, which is exactly the probate-court involvement most people are naming a beneficiary to avoid.
