On a beneficiary designation form, allocation means how you divide the account’s proceeds among the people or organizations you name. In practice, that almost always takes the form of percentages assigned to each beneficiary that add up to 100%, together with the rules that decide what happens to a share if a beneficiary dies before you do. So the question of what allocation means in a beneficiary designation has two parts: the split you write on the form, and the formula that resolves that split when the account actually pays out.
The Percentage Split
The most common way to allocate is by percentage. You assign each beneficiary a share of the account’s value, and the shares must total 100%. A parent with three children might put roughly 33% next to each child’s name. The advantage of percentages is that as the account grows or shrinks, every beneficiary’s dollar amount adjusts automatically while their proportional share stays the same.
Allocations are entered separately for primary and contingent beneficiaries, and each group totals 100% on its own. Primary beneficiaries are first in line. Contingent, or secondary, beneficiaries only receive anything if every primary beneficiary is unable to take the assets, whether because they died first, can’t be located, or refuse the inheritance. A common setup is a spouse at 100% as the sole primary beneficiary, with two children listed as co-contingents at 50% each.
These forms live with the plan administrator or financial institution: 401(k) and IRA beneficiary forms, life insurance beneficiary forms, payable-on-death (POD) designations on bank accounts, and transfer-on-death (TOD) registrations on brokerage accounts. All of them pass assets directly to the named beneficiaries without going through probate.1Legal Information Institute. Transfer-on-Death (TOD)
What Happens If a Beneficiary Dies Before You
The percentages are only half of the allocation. The other half is the formula that decides where a deceased beneficiary’s share goes. Most forms ask you to choose between per stirpes and per capita, and the two produce very different results.
Per Stirpes
Per stirpes means “by branch.” Each branch of your family tree gets an equal share, and if a beneficiary in one branch dies before you, their share passes down to their own descendants rather than shifting over to the other branches.2Legal Information Institute. Per Stirpes
Take a mother who splits her estate equally between her two children, Alice and Ben, with a per stirpes designation. Alice dies first, leaving two children of her own. Alice’s 50% share does not go to Ben. It splits equally between Alice’s two children, who each receive 25% of the total. Ben still receives his original 50%. Each family branch is protected even when a member of that branch is gone.
Per Capita
Per capita means “by the head.” On a financial account beneficiary form, selecting per capita typically means that if a named beneficiary dies before you, their share is redistributed among the surviving named beneficiaries rather than passing to the deceased beneficiary’s descendants.3Legal Information Institute. Per Capita In the example above, Alice’s 50% would go to Ben, and Alice’s children would receive nothing from the account.
Per stirpes protects each branch of the family and is the safer default for most people with children and grandchildren. Per capita on a beneficiary form can accidentally disinherit an entire branch if one of your children predeceases you. Match the formula on each account to what you actually want to happen.
The 120-Hour Survival Rule
Allocation also has to deal with near-simultaneous deaths. Most states have adopted a version of the Uniform Simultaneous Death Act, under which a beneficiary generally must survive the account holder by at least 120 hours (five days) to inherit. If the beneficiary doesn’t survive that window, the assets are treated as though that beneficiary died first, and the allocation moves to the contingent beneficiary or follows the per stirpes or per capita formula.4Legal Information Institute. Uniform Simultaneous Death Act
The Allocation on the Form Overrides Your Will
This catches people constantly. If your will says your spouse inherits your IRA, but the IRA’s beneficiary form still names your children, your children get the IRA. The beneficiary designation on the account wins every time, regardless of what the will says.5Vanguard. What Is a Beneficiary? Types and How to Choose The same rule applies to life insurance policies, 401(k) plans, and any account with a direct beneficiary designation. Updating your will alone is never enough. After any marriage, divorce, birth, or death in the family, review the beneficiary forms on each individual account.
Allocation Traps to Watch For
Allocating to a Minor
Naming a minor child directly in the allocation creates a practical problem: minors generally cannot control inherited assets. If a child under 18 is listed for a share of a life insurance payout or retirement account, a court may need to appoint a guardian or custodian to manage those funds until the child reaches adulthood. The cleaner approach is to allocate the share to a custodial account under your state’s Uniform Transfers to Minors Act (UTMA), or to name a trust as the beneficiary with the minor as the trust’s beneficiary.
Allocating to Someone on Means-Tested Benefits
If a beneficiary receives Supplemental Security Income (SSI) or Medicaid, a direct allocation can be devastating. SSI limits countable resources to $2,000 for an individual, and even a modest inheritance can push someone over that threshold, cutting off benefits they depend on. A properly drafted special needs trust can hold the allocation without counting against the beneficiary’s resource limits. Federal law allows a trust containing the assets of a disabled individual under age 65 to be excluded from Medicaid’s asset calculations, as long as it is established by a parent, grandparent, legal guardian, or court, and includes a provision requiring that any remaining funds at the beneficiary’s death repay the state for Medicaid expenses.6Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets The trust must be irrevocable and managed by a trustee with full discretion over distributions. The trust has to be in place before the allocation transfers.
Allocations After Divorce
Many states have “revocation on divorce” statutes that automatically cancel an ex-spouse’s beneficiary designation when a divorce is finalized. The law treats the ex-spouse as having predeceased the account holder, which pushes the allocation to the contingent beneficiary or through the chosen distribution formula. The U.S. Supreme Court upheld the constitutionality of these state laws in Sveen v. Melin (2018), even when applied retroactively.7Supreme Court of the United States. Sveen v Melin, 584 US 488 (2018)
There is a major exception. Employer-sponsored retirement plans and group life insurance policies governed by the federal Employee Retirement Income Security Act (ERISA) are not affected by state revocation-on-divorce laws. In Egelhoff v. Egelhoff (2001), the Supreme Court held that ERISA preempts state laws that would override the beneficiary designation on file with the plan administrator.8Legal Information Institute. Egelhoff v Egelhoff, 532 US 141 (2001) A 401(k) or employer-provided life insurance policy will still pay out to the ex-spouse unless the participant actively changes the allocation after the divorce. If you’ve been through a divorce, do not assume your state’s automatic revocation law covers every account. Review and manually update every beneficiary form.
What Happens If the Allocation Is Blank or Incomplete
When beneficiary designations are missing, outdated, or ambiguous, the fallback rules rarely match what the account holder intended. For retirement accounts and life insurance policies, the financial institution will typically distribute the proceeds according to its default plan provisions, which often means paying the money to the deceased’s estate.9Internal Revenue Service. Retirement Topics – Beneficiary Once the assets land in the estate, they are subject to probate, a court-supervised process that can take months and generate costs from filing fees, attorney fees, and executor compensation. Probate also makes the distribution public and can expose the assets to the deceased’s creditors.
If there is no will, state intestacy laws take over. Intestacy statutes prescribe a rigid formula for dividing property among surviving relatives, typically prioritizing a spouse and children, and they leave no room for the deceased’s actual preferences.10Legal Information Institute. Intestate Succession Unmarried partners, stepchildren, close friends, and charities receive nothing under intestacy unless a valid designation or will names them. For retirement accounts specifically, losing the named-beneficiary status can also strip away favorable tax treatment that would have been available to an individual beneficiary.
The short version: the allocation on each beneficiary form is a self-contained set of instructions. Percentages that total 100%, a chosen distribution formula, and a contingent layer behind the primary one. Keep each account’s form current, and the allocation does exactly what you set it to do.
