Many people save for retirement in a defined-contribution retirement plan (like a 401k) or an individual retirement account (traditional or Roth IRA). It is important to designate beneficiaries for accounts. The forms, often seemingly simple to fill out, have hidden complexity.
You are likely to encounter the words “per stirpes,” which means “by roots” in Latin. In the estate planning context, it means that assets will be distributed along the “roots” of lineal descendants, preserving a bequest to a line of heirs if one person in a generation predeceases the person bequeathing the assets. The opposite would be a default of “per capita,” which would give an equal share to each person in an equal degree of relationship to the deceased (e.g. 3 children). This small checkbox can have meaningful consequences to a family, as explained in the charts below.
I. Base Case Scenario
Let’s start with a scenario of a matriarch who will leave $300,000 in an IRA to her three children. She also has three grandchildren, although her daughter has no children. In a basic scenario, her three children living at the time of death would split the assets equally and receive $100,000 each. Whether or not the per stirpes box was checked has no impact if all primary beneficiaries are living. (For simplicity’s sake, we are ignoring any final expenses, fees, and transfer taxes upon the disposition of assets at death).

II. Scenario 1 – Son 1 Predeceases Mother and Per Stirpes is not Elected
Unfortunately, in this scenario Son 1 has predeceased his mother. The per stirpes designation was not elected. We assume that the matriarch’s wish was to have Son 1’s share pass to his children to be kept in line. Her will may have expressed that wish, but an IRA beneficiary form will supersede the will. In this scenario, the assets will now be split equally among her two living children, as shown in Figure 2 below. The deceased son’s children will not receive their father’s share.

III. Scenario 2 – Son 1 Predeceases Mother and Per Stirpes is Elected
In scenario 2, Son 1 has predeceased his mother. If the three primary beneficiaries had been designated “per stirpes,” the assets would be kept in lineal descent with Son 1’s share of the assets going to the next generation. His share (1/3 of the $100,000) is now split equally among his heirs, as shown in Figure 3.

IV. Scenario 3 – Daughter Predeceases Mother
In this final scenario, the daughter, who does not have any children, predeceases her mother. Since she does not have children to receive her share of the assets, the total amount will now be split among the two living primary beneficiaries. The per stirpes election does not come into play.

V. Concluding Thoughts
It is important to review your beneficiary designations on retirement plans, individual retirement accounts (IRAs), and insurance policies at regular intervals, especially if there has been a change in your personal situation like a marriage, divorce, birth, or death. Retirement account beneficiaries are not processed through probate court,1 saving time, expense, and possibly taxes. Importantly, beneficiary designations on retirement accounts overrule what is written in a will. If the two documents differ, the beneficiary designation is what will be followed by the custodian or plan administrator.
While this commentary is meant to explain the use of the per stirpes designation, each individual or family’s desires may vary and we have made a number of potentially limiting assumptions. Planning should be done in consultation with an estate planning attorney to ensure that your wishes will be carried out. Also, beneficiary allowances may vary by custodian, retirement plan or state.
