Beneficiary forms beat your will — a 20-minute autumn check-up

The forms on your 401(k), IRA and life insurance decide who gets the money, whatever your will says. Here's how to check them in one sitting.

Most people picture a will as the document that decides who inherits what. For a surprising share of a family's money, it isn't. Retirement accounts, life insurance, annuities and many bank and brokerage accounts pass by the beneficiary form on file with the institution — and that form wins even when the will says something different.

Why the form outranks the will

A beneficiary designation is a contract between you and the account holder. When you die, the company pays the person named on its records, usually within weeks and outside probate. Courts have repeatedly upheld designations naming an ex-spouse, a parent who has since died, or a child who was a minor when the form was signed. The will simply never gets a say.

  • Retirement accounts: 401(k), 403(b), IRA, Roth IRA, pensions with survivor options
  • Insurance: life, accidental death, some disability policies with death benefits
  • Bank and brokerage accounts with "payable on death" or "transfer on death" instructions
  • Some state vehicle titles and, in a growing number of states, real estate deeds

The 20-minute check-up

You don't need a lawyer for this pass — just a list of accounts and a quiet evening. Log in to each one, find the beneficiary page, and answer three questions.

  1. Is the primary beneficiary still the person you'd choose today?
  2. Is there a contingent (backup) beneficiary in case the primary dies first?
  3. Do the percentages add up to 100%, and do the names match legal names?

Write down the date you confirmed each one. If an institution has no beneficiary on file, that account will go through probate — often the slowest and most expensive path.

The mistakes that cause the most grief

  • Naming a minor child directly. Insurers won't pay a child; a court appoints a guardian for the money instead. Name a trust or a custodian under your state's UTMA rules.
  • Forgetting the contingent. If your spouse is the only name and you die together, the money goes to probate.
  • Leaving "estate" as the beneficiary of a retirement account. It usually forfeits the stretch-out options heirs would otherwise have and can accelerate the tax bill.
  • Never updating after a divorce, remarriage or a birth.

Spend twenty minutes this month and your family will never have to argue with a claims department about who you meant.
