US FederalCan I change the beneficiary on my retirement plan without my spouse's consent?
Generally, no—you cannot change the beneficiary on a qualified retirement plan (like a 401(k) or pension) without your spouse’s written consent if you are married and the plan is subject to ERISA.
What the Law Says
Federal law—specifically the Employee Retirement Income Security Act (ERISA)—sets baseline protections for retirement plans, including rules about beneficiary designations. While 29 U.S.C. § 1001 states Congress’s broad policy goals, the specific spousal consent requirement comes from other ERISA provisions (e.g., § 1055), which mandate that a married participant in a qualified plan must obtain written, witnessed spousal consent to name anyone other than their spouse as beneficiary—or to change that designation.
ERISA does not itself list the spousal consent rule in § 1001, but that section declares the law’s foundational purpose: 'to protect the interests of participants in employee benefit plans and their beneficiaries.' This policy underpins later, more specific requirements—including those in § 1055—designed to safeguard spouses’ rights to survivor benefits.
For qualified retirement plans (such as 401(k)s, pensions, and profit-sharing plans), federal law presumes the spouse is the automatic beneficiary unless the spouse consents in writing to another designation. That consent must be voluntary, witnessed by a plan representative or notary, and acknowledge the effect of the waiver.
Statutory TextThe purposes of this subchapter are to provide a program which shall encourage the establishment and maintenance of private employee benefit plans... and to protect the interests of participants in employee benefit plans and their beneficiaries...

What to Do
Confirm whether your plan is an ERISA-covered qualified plan (most employer-sponsored 401(k)s and pensions are).
Contact your plan administrator to request the official spousal consent form.
Have your spouse sign the form in the presence of a plan representative or notary.
Submit the completed, signed form to the plan administrator before the change takes effect.
Keep a copy of the signed consent for your records.
