How to name beneficiaries and fund a trust at Unum

Beneficiaries are managed online or by mail. Trust paperwork is taken by mail

Estate planning with Unum policies centers on beneficiary designations—the single most important step for ensuring life insurance proceeds and annuity benefits reach the intended recipients without probate involvement. Unlike bank or brokerage accounts, insurance products are not retitled into trusts; instead, trusts are named as beneficiaries when estate tax planning or controlled distributions are needed.

Unum has 10 product types, and the estate transfer rules differ across them. Some support beneficiary designations, some can be retitled into a trust, and others pass through the estate if nothing is set up. Each is covered below.

What Unum says about beneficiaries and trusts

Each section is Unum's own statement, with the document it comes from numbered under Sources.

Which accounts take a beneficiary1

Life insurance policy

While you are employed, a group life or AD&D beneficiary designation on form CS-1110 is returned to your employer, not to Unum.1

Ported group life uses form CS-1277, sent to Unum. Voluntary benefits policies, including whole life, use form L-52490, by mail or electronic signature.2, 3

Who can be named1

A trust

A valid trust may be designated as a beneficiary. The voluntary benefits form asks for the date of the trust.4

How many beneficiaries, and how shares are split

Life insurance policy

Primary and contingent beneficiaries can be named, with percentages totaling 100% at each level.2

If more than one beneficiary is named and no percentages are indicated, payment is made to them in equal shares (forms CS-1110 and CS-1277).1, 2

What a designation takes to be effective

Life insurance policy

Voluntary benefits forms carry owner, spouse and assignee signature lines and a notice for residents of the community property states AZ, CA, ID, LA, NV, NM, TX, WA and WI.3

What Unum's agreement says about beneficiaries4

Changing or revoking a designation

Forms CS-1110, CS-1277 and L-52490 each cancel all prior designations, so every beneficiary you want to keep is listed again.1, 2, 3

An absolute assignment of group life (CS-1179) revokes all prior beneficiary designations and names the assignee as the beneficiary. After Unum acknowledges it, only the assignee can change the beneficiary.6

A beneficiary who dies first

If a primary beneficiary is disqualified or dies before the insured, that share is paid to the remaining primary beneficiaries (forms CS-1110 and CS-1277).1, 2

A minor as beneficiary

Unum states that insurance benefits may not be released to a minor child but may be paid to a child's court-appointed financial guardian.2

Changing the owner of a policy or account

On Unum's assignment form, an assignment with no box checked is treated as a collateral assignment, not an absolute one.6

What Unum says about trust accounts2

A trust as owner of a policy

Group life can be assigned to a trust: Unum's assignment forms transfer the insured's current and future rights under the policy "to the person, trust or company listed below."6

The assignee holds the insured's rights under the policy, including changing beneficiaries and applying for conversion or portability.6

Unum states it is not responsible for the legal, tax or other effects of the assignment, or for its validity or sufficiency.6, 7, 8

Changing or revoking a designation

An absolute assignment revokes all prior beneficiary designations and names the trust as beneficiary. After Unum acknowledges it, only the assignee can change the beneficiary or release the assignment, and it stays in place until Unum receives an acceptable release.6
