To split life insurance beneficiaries, you list each person or entity on your policy’s beneficiary designation form and assign each one a percentage of the death benefit, with all shares adding up to 100%. A $500,000 policy might send 50% to a spouse, 25% to one child, and 25% to another. The insurer pays each named beneficiary their share directly. The mechanics are simple; the decisions around them are where policies go wrong.
Assigning Percentages and Naming Backups
Every policy lets you name one or more primary beneficiaries and set each one’s percentage. You can divide the payout however you want as long as the shares total 100. Three children in equal shares is 33.33% each. A spouse-heavy split might be 70% to the spouse and 15% each to two siblings. Whole numbers are easier to read on a form, but insurers accept decimals.
Don’t rely on the insurer to divide the money equally by default. Some do, some don’t, and the wording of “equally” on a form isn’t always interpreted the way you’d expect. Write the exact percentages every time.
Contingent beneficiaries are the backups. They receive the death benefit only if every primary beneficiary has died or can’t be located. Without contingents, an unclaimed primary share can fall into your estate and go through probate, which means court involvement, legal fees, and delay. Name at least one contingent for each primary share.
Per Stirpes or Per Capita
These two words control what happens to a beneficiary’s share if that person dies before you do. Most people never think about the choice, and it changes who ends up with the money.
Per stirpes passes a deceased beneficiary’s share down to that person’s own children. Say a $600,000 policy is split equally among three children at $200,000 each, and one child dies before you. That child’s $200,000 goes to their kids. The other two children still get $200,000 each.
Per capita redistributes the deceased beneficiary’s share among the surviving named beneficiaries. Same example: if one of three children dies first, the remaining two each get $300,000, and the deceased child’s kids get nothing from the policy.
Neither is automatically better. Per stirpes protects grandchildren; per capita concentrates the money among survivors. The point is to choose deliberately and use the wording your insurer requires. Companies won’t apply per stirpes unless you specifically request it, and the exact phrasing varies.
If You’re Married, Your Split Has Limits
Your freedom to divide the death benefit isn’t absolute if you have a spouse. In the roughly nine community property states, a policy paid for with marital income can be treated as jointly owned, and your spouse may have a legal claim to up to half of the death benefit even if they aren’t on the form. This can apply to a policy you bought before the marriage if premiums came from joint income afterward. A written agreement between spouses can override the default, but without one the community property claim stands.
Outside community property states, many jurisdictions still require written spousal consent before you can name someone other than your spouse as primary beneficiary. If you’re married and want to leave the entire benefit, or most of it, to someone else, check your state’s rules and get any required consent in writing. State law can override what your beneficiary form says.
When a Share Goes to a Minor
Insurers won’t pay a death benefit directly to a minor. If you name a 10-year-old for 25% of a policy without further planning, the insurer holds that share until a court appoints a guardian. That means delay, legal costs, and a guardianship arrangement you had no say in.
The cleaner options:
- Set up a trust for the child and name the trust as the beneficiary for that share. You choose the trustee, set the terms (education only, staggered distributions after age 25, whatever fits), and keep a large payout from landing in an 18-year-old’s checking account.
- Appoint a custodian under the Uniform Transfers to Minors Act. Most states have adopted UTMA. The custodian manages the funds until the child reaches the age of majority, which is 18 in most states and 21 in a few. The catch: once the child hits that age, they get full control of every dollar. For a large share, a trust gives you far more control.1Social Security Administration.

When a Share Goes to a Disabled Dependent
Naming a dependent adult with a disability as a direct beneficiary is one of the costliest mistakes in beneficiary planning. A lump-sum payout counts as a resource for Supplemental Security Income, and the SSI resource limit is just $2,000 for an individual. Going over that on the first day of any month suspends benefits for that month, and 12 consecutive months of suspension can result in permanent termination.
A special needs trust solves this. Federal law creates an exception for trusts established for a disabled person under age 65 by a parent, grandparent, guardian, or court. Assets in a qualifying trust aren’t counted against the beneficiary’s resource limit for Medicaid or SSI.2Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets The trust can pay for supplemental needs (specialized equipment, travel, personal care) without jeopardizing government benefits. The tradeoff: any funds left in the trust when the beneficiary dies must reimburse the state for Medicaid payments made on their behalf.
An ABLE account can sit alongside a trust as part of a broader plan. These tax-advantaged accounts are available to individuals whose disability began before age 46, and the first $100,000 in an ABLE account is excluded from SSI resource calculations.3Social Security Administration. Spotlight On Achieving A Better Life Experience (ABLE) Accounts The 2026 annual contribution limit is $19,000, so an ABLE account won’t hold a full death benefit, but it works well as a companion to a special needs trust.
Making the Split Actually Stick
Here’s the fact that catches people off guard: the beneficiary form overrides your will. If your will leaves everything to your current spouse but the policy still names your first spouse from a decade ago, the insurer pays the first spouse. Courts have upheld this repeatedly. The beneficiary form is a contract between you and the insurer, and the will has no power to change it.
That means beneficiary designations are part of your estate plan, not a separate task you set and forget. If you have a revocable living trust and want proceeds to flow through it, name the trust as the beneficiary on the policy form. Mentioning the policy in the trust document doesn’t redirect the payout. When naming a trust, use its full legal name and the date it was established. A mismatch between the name on the policy and the name in the trust document can delay payment. Some insurers require specific language; ask.
Update After Life Events
Marriage, divorce, the birth of a child, the death of a beneficiary, and any major change to your estate plan all call for an update. Verbal requests, handwritten notes, and will provisions don’t move the needle. You submit a written change-of-beneficiary form to the insurer, and the insurer honors only the most recent properly filed form. After you submit, confirm in writing that the change was recorded with the correct names, percentages, and distribution method.
Divorce Is the Big One
Most states have revocation-upon-divorce statutes that automatically cancel an ex-spouse’s beneficiary designation once the divorce is finalized. The ex is treated as having predeceased you, and the benefit passes to contingents or your estate.4Supreme Court of the United States. Sveen v Melin, 584 US 18-138 (2018)
There’s a major exception for employer-sponsored life insurance governed by ERISA. The Supreme Court held that ERISA preempts state revocation-upon-divorce laws.5Legal Information Institute. Egelhoff v Egelhoff, 532 US 141 (2001) The plan administrator must follow whatever designation is on file. If your workplace form still names your ex, the ex gets paid. This is the single most common way divorced people accidentally leave a death benefit to the wrong person. After a divorce, update every beneficiary form you have, and treat the workplace policy as the most urgent.
Other Things That Can Undo a Split
Every state has some version of the slayer rule: a beneficiary responsible for the insured’s death cannot collect. The killer is treated as having predeceased the insured, and the money passes to contingents or the estate. Federal courts have applied the same principle to ERISA plans.
If you and a primary beneficiary die in the same accident and it isn’t clear who died first, most states follow the Uniform Simultaneous Death Act, which presumes the beneficiary died first. The payout then goes to contingents or your estate rather than flowing into the deceased beneficiary’s estate. You can add a survivorship clause requiring a beneficiary to outlive you by a set period, often 30 or 60 days, to reach the same result in close-call cases.
When competing claims arise, an insurer can file an interpleader action, deposit the full death benefit with a federal court, and let the claimants fight it out.6Office of the Law Revision Counsel. 28 USC 1335 – Interpleader That means delay and legal costs eating into the payout. Clear, current beneficiary designations are the best way to keep the split you designed from becoming someone else’s court case.
