The key to protecting your Northwestern Mutual Investment Services investment accounts is making sure each one has a transfer mechanism in place—either a beneficiary designation or trust ownership. Without one, the account goes through probate, adding time, cost, and court involvement for your family.

Each of Northwestern Mutual Investment Services's 13 investment accounts has different rules for how it transfers at death. The sections below explain the options for each.

1
Meet your Northwestern Mutual financial representative at their local office and bring government-issued photo ID.
2
Tell them which designation you need — they are different instruments:
  • A TRANSFER-ON-DEATH (TOD) registration on a taxable brokerage or advisory account, which sends the account to a named beneficiary outside probate
  • A BENEFICIARY DESIGNATION on an IRA, which is the only way an IRA passes (an IRA cannot be retitled to a trust)
  • A SUCCESSOR OWNER on a 529, which is what actually controls the account if you die — not the 529's "beneficiary," who is the student
3
Give each beneficiary's full legal name, date of birth, Social Security number, relationship, and percentage allocation, plus contingent beneficiaries.
4
Sign the form. The representative submits it to NMIS, which puts the registration in place with the custodian.

Required Documents

  • Trust name, date established, and tax ID (EIN or SSN)

Special Requirements

  • No online beneficiary self-service for investment accounts — everything runs through a financial representative or Investment Client Services
  • Neither Northwestern Mutual nor its clearing firm publishes a TOD or IRA beneficiary form publicly; the form comes from the representative
  • (866) 950-4644 is investment products only. Life insurance: (877) 394-9524. Universal life: (866) 464-3800. Annuities: (866) 269-2950
  • An IRA is passed by beneficiary designation only and must never be retitled into a trust
  • A 529 needs a SUCCESSOR OWNER named; its "beneficiary" is the student and does not govern what happens if the owner dies
  • An UGMA/UTMA needs a successor custodian, not a beneficiary — the assets already belong to the minor
