Percentage Splits That Do Not Add Up

Beneficiary forms ask for shares expressed as percentages. The arithmetic looks trivial, and it is one of the more common ways a designation produces an unintended result.

Totals that miss the mark

Forms generally require the primary shares to total one hundred, and many custodians reject a submission that does not, which at least surfaces the error immediately.

The dangerous case is a form that is accepted with an error, leaving the custodian to allocate an unassigned remainder according to its own account agreement.

Rounding causes the same trouble. Three equal beneficiaries cannot be expressed exactly in whole percentages, and how the odd fraction is handled depends on the institution.

Shares are usually not adjusted automatically

If one of several named beneficiaries has died, the account holder may assume the remaining shares simply expand to fill the gap.

Whether that happens depends on the form's terms and whether per stirpes or similar language was used, and defaults differ between custodians.

Without that language, a deceased beneficiary's share may pass to contingent beneficiaries or to the estate rather than to the surviving named individuals.

Dollar amounts do not belong on these forms

Some people write a fixed sum next to one name, intending a specific legacy, but most designation forms operate only on proportions of whatever the account holds.

An account that grows or falls substantially makes a fixed intention meaningless anyway, since the balance at death is what is being divided.

Where a specific amount genuinely matters, that objective usually belongs in a different instrument, which is a conversation for an estate attorney.

Multiple accounts multiply the error

People frequently hold several retirement and investment accounts, each with its own form completed at a different time and often with different splits.

The intended overall division across a family is therefore the sum of several separate forms, and nobody reviews that total until after a death.

Because balances shift at different rates, a division that was equal when the forms were signed rarely remains equal years later.

How to verify what is on file

Requesting written confirmation of the designation of record from each custodian is the only reliable check, since assumptions about what was submitted are frequently wrong.

Custodian rules on rounding, unassigned shares and deceased beneficiaries are set in account agreements that change over time.

Where the split needs to work alongside a will or trust, the estate attorney and the custodian should both see the intended wording before it is filed.
