An individual retirement account with a living, named beneficiary does not pass through a decedent’s will and does not sit in a probate court file. The account moves directly to whoever is listed on the beneficiary form the custodian has on record, regardless of what any will says or who inherits other property. That distinction catches many families off guard, because it means an outdated or missing beneficiary form can override even a carefully drafted estate plan.
The Beneficiary Form Controls, Not the Will
Retirement accounts are treated as contract assets rather than probate assets, and that classification is what allows them to bypass the court process entirely. The account owner designates a beneficiary directly with the IRA custodian, separately from any will, trust, or other estate document, using a form supplied by the financial institution holding the account. That designation is a standing instruction the custodian is required to follow the moment the owner dies, independent of anything else the family may later present in court.
According to the IRS’s guidance on retirement account beneficiaries, a beneficiary is generally any person or entity the owner chooses under the procedures established by the plan or custodian, and that choice governs the transfer no matter what instructions appear in a separate will. A will covers only the property a person owned outright in their own name; it has no authority over an account that already has a valid, living beneficiary attached to it. Some retirement plans even require specific beneficiaries under the plan’s own terms, such as a spouse, which can further limit what a will could ever change even if it tried.

Required Withdrawals Depend on Who Inherits
Once an IRA passes to a beneficiary, the rules governing how quickly the money must come out shift, and those rules differ sharply depending on the relationship between the beneficiary and the original owner. A surviving spouse who is the sole beneficiary generally has the most flexibility: the account can be rolled into the spouse’s own IRA, kept as an inherited account and drawn down over a life expectancy, or in some cases follow a set withdrawal schedule. Determining whether the spouse counts as the sole beneficiary is generally measured as of September 30 of the year following the year of the owner’s death, so the paperwork on file at that point matters.
A non-spouse beneficiary faces tighter limits. Under the SECURE Act, most non-spouse beneficiaries of an owner who died in 2020 or later must empty the account within ten years, unless they qualify as an “eligible designated beneficiary,” a narrower category that includes minor children, disabled or chronically ill individuals, and people not more than ten years younger than the original owner. Full mechanics of these categories, along with the older five-year and life-expectancy rules that still apply to some accounts, are laid out in IRS Publication 590-B, the agency’s guide to IRA distributions.
What Happens Without a Current Beneficiary on File
The probate-avoiding effect only works when a valid beneficiary designation actually exists. If an account owner never named a beneficiary, or the named beneficiary died first and no contingent beneficiary was listed, the account typically defaults back into the owner’s estate. Once that happens, the money is distributed according to the will, or under state intestacy law if there is no will, and it becomes subject to the same probate process, court oversight, and potential delays that beneficiary designations are meant to bypass. It can also lose the flexible, beneficiary-specific distribution options described above, since an estate is not treated the same way as an individual beneficiary for required-withdrawal purposes, which can force a faster and less favorable payout schedule than a named person would have received.
Why the Form Needs Regular Updates
Because the beneficiary form overrides the will, an outdated form is one of the more common estate-planning mistakes. A divorce, a remarriage, the birth of a grandchild, or the death of a previously named beneficiary can all leave a form pointing to the wrong person years after the owner’s circumstances changed. Custodians generally do not update beneficiary designations automatically when personal situations change; the account owner has to submit a new form, and many people simply forget the form exists once the account has been open for years.
Naming both a primary and a contingent beneficiary adds a layer of protection, since the contingent beneficiary steps in if the primary beneficiary has already died, which keeps the account from defaulting to the estate and losing its probate-avoiding status. Reviewing beneficiary forms after any major life event, and at minimum every few years, is the simplest way to make sure an IRA actually goes to the person the owner intended rather than getting tied up in a court process it was never supposed to touch.
