Avoiding Costly Errors When Naming Retirement Beneficiaries

October 3, 2026 - 22:09

Retirement accounts now hold more than $30 trillion in assets, according to the Investment Company Institute, as 401(k) plans and IRAs have largely replaced traditional pensions for most private sector workers in the United States. That shift has placed a heavy responsibility on account holders, who must decide who receives the money after they die. Mistakes in that process are common, and they can be expensive for the people left behind.

One frequent problem is failing to update beneficiary forms after a major life event. A divorce, a death, or the birth of a child can change a person's intentions, yet the paperwork often stays untouched for years. In many cases, the named beneficiary on file overrides instructions left in a will, which means an ex-spouse or a deceased relative could end up with the funds.

Another error involves naming a minor child as a direct beneficiary. Because minors cannot legally control inherited assets, the court may appoint a guardian to manage the money, and the child typically gains full access at 18 or 21. A trust often works better for families in this situation.

Some account holders also forget to name a contingent beneficiary. If the primary beneficiary dies first, the assets may pass through probate, where they can be tied up for months and exposed to creditors. Others leave the beneficiary line blank entirely, which produces the same result.

A final mistake is assuming a will covers everything. It does not. Retirement accounts follow their own rules, and the forms attached to them carry the final word. Reviewing those designations every few years, and after any significant change in life, remains one of the simplest ways to protect an estate.
