Remarrying at 68 Can Redirect Your 401(k) to Your New Spouse Unless She Signs a Notarized Waiver; IRAs Work Differently and the Will Does Not Control Either

Federal law can override a carefully prepared beneficiary form the moment you remarry, and even a lawyer-drafted will may not prevent your 401(k) from going to your new spouse.

A 68-year-old retired engineer in Ohio, widowed for a decade, marries again. He has a $700,000 401(k) from a former employer and a $300,000 rollover IRA. His will, written after his first wife died, leaves everything equally to his two adult children. Both beneficiary forms also list the children.

When he dies 19 months after the wedding, the children bring the will to the 401(k) plan administrator and learn that it carries no weight there. The plan sends the full $700,000 to the widow. The children receive the $300,000 IRA, or $150,000 each.

Everything was completed on paper, but one step never happened: the new wife did not sign a waiver. From the date of the marriage, federal law made her the 401(k) beneficiary.

Federal Law Places the New Spouse First for a 401(k)

A 401(k) is governed by survivor-benefit rules in Internal Revenue Code section 401(a)(11). Most plans can avoid mandatory annuity requirements only if the account balance is paid in full at the participant’s death to the participant’s surviving spouse. Someone else can receive the money only if there is no surviving spouse, or if the spouse gives consent in the manner required by section 417(a)(2).

That consent must be in writing, must acknowledge what it does, and must be witnessed by a plan representative or a notary public under section 417(a)(2)(A). IRS Publication 560 says the same thing: a spouse’s consent must be witnessed by a plan representative or notary public.

Timing also matters. A waiver signed in a prenuptial agreement does not work because the signer was not yet a spouse. The consent must be signed after the wedding, while she is the spouse. A plan may choose to deny spousal rights in marriages shorter than one year, but that is optional. In this case, the marriage lasted 19 months, so it was beyond that cutoff anyway.

IRAs Follow the Beneficiary Form, and Neither Account Is Controlled by the Will

Section 408 defines an IRA as a trust for the exclusive benefit of an individual or the individual’s beneficiaries, and it does not impose a spousal-consent rule. The person named on the custodian’s beneficiary form inherits. In community-property states, state law can give a spouse a claim to IRA funds earned during the marriage. Ohio is a common-law state, so the form controls.

Both accounts pass outside the will, through contract and beneficiary designation. In Egelhoff v. Egelhoff, the U.S. Supreme Court held that ERISA preempted a Washington law that would have redirected employer-plan benefits, and the named beneficiary kept the money.

One Estate, Two Very Different Outcomes

The widow’s $700,000 may leave his family line permanently. Section 402(c)(9) lets a surviving spouse roll over a plan distribution as if the spouse were the employee. Once the money is in her own IRA, she can name her own beneficiaries. If she has children from a prior marriage, they move to the front of the line.

The children’s $300,000 is not unrestricted either. As non-spouse heirs, they are subject to the SECURE Act rules added to section 401(a)(9), which generally require inherited accounts to be emptied within 10 years.

Either of Two Simple Steps Could Have Protected the Children’s Share

There were two straightforward ways to avoid this result. First, he could have rolled the 401(k) into an IRA before the wedding. Before marriage, no spouse signature is needed, and once the money is in an IRA, the beneficiary form alone determines who gets it. In that case, each child would receive $500,000.

Second, he could have kept the 401(k) and had his new wife sign the plan’s spousal consent form after the wedding, in front of a notary or plan representative. That would have produced the same result: $500,000 to each child. If he wanted to provide for her separately, life insurance or a specific bequest in the will could do that without affecting the retirement accounts.

Checklist to Preserve the Children’s Inheritance

• Call the 401(k) plan administrator and ask for the spousal consent form, along with the plan’s rule for marriages shorter than one year.
• Decide before the ceremony whether to roll an old employer’s 401(k) into an IRA, where federal law does not require a spouse’s signature.
• Sign the prenup, then have the spouse sign the plan consent form after the wedding, with a notary or plan representative as witness. Keep a copy and confirm that the plan has one on file.
• Review every 401(k) and IRA beneficiary form and compare each one with the will. If they conflict, the beneficiary form controls.
• In a community-property state, ask legal counsel whether the IRA also needs spousal consent.

Beneficiary forms, ownership rules, and the gap between what a will says and what a retirement plan pays are the paperwork that decides whether money stays with family or goes elsewhere. A full checklist belongs in a free estate guide.

One Missing Signature Can Shift $700,000

Households headed by people ages 55 to 69 hold 49.5% of all defined contribution retirement wealth in the United States. For remarried savers in that group, the key figure is $700,000: the 401(k) that went to a spouse of 19 months because one notarized form was never signed.
