Expanding Spousal Consent for 401(k)s: The Policy Trade-offs Congress Is Weighing
Extending spousal consent requirements to all defined contribution plans sounds straightforward on paper. If a spouse can veto a beneficiary change in most 401(k) plans, why can’t they veto a $50,000 withdrawal? The answer, according to a March 2026 GAO report, is a web of administrative, legal, and philosophical trade-offs that make the issue considerably more complex than it first appears.
The Case for Expanding Requirements
The current system is, as the GAO frames it, a historical accident. Spousal consent rules were built around annuity-based retirement plans — defined benefit pensions and the few defined contribution plans that also offer lifetime annuity payouts. The 401(k), which now dominates the private-sector retirement landscape, arrived after the framework was constructed and was designed as a savings vehicle, not a pension substitute. It was slotted into the lighter-touch regulatory category and has stayed there.
Advocates for expanding spousal consent point to the parallel with defined benefit plans, which do require such consent. As one Senate committee report quoted in the GAO document put it, a spouse “should be involved in making choices with respect to retirement income on which the spouse may also rely.” The American Academy of Actuaries, in a 2025 paper, argued that unilateral participant decision-making can directly jeopardize a spouse’s retirement security.
In divorce proceedings, the case is particularly concrete: spousal consent requirements would prevent a participant from liquidating a retirement account after filing for divorce but before a Qualified Domestic Relations Order is in place to protect the spouse’s share.
The Case Against — or for Caution
Retirement industry stakeholders interviewed by the GAO raised several objections:
Administrative cost. Adding spousal consent requirements means collecting marital status information, verifying it, routing consent forms, and managing exceptions. Record keepers currently don’t systematically collect marital status data. Most rely on participant self-reporting. Spousal consent requirements would need to sit on top of an infrastructure not built to support them, potentially requiring system changes, additional staff, and updated plan documents. These costs would likely be passed to participants.
Small plan burden. A large plan sponsor can spread implementation costs across millions of participants. A small employer running a 401(k) for 30 employees faces the same compliance overhead at a much higher per-person cost.
Processing delays. One record keeper told the GAO that transactions requiring spousal consent currently take a week or more, compared to two to three days for standard transactions. In situations where a participant needs emergency access to funds, that delay can be consequential.
Autonomy. Some groups representing women retirees raised the counterintuitive point that because women are less likely to hold retirement accounts, those who do may resist requirements that give a spouse veto power over their own savings.
What Record Keepers Actually Said
Two record keepers with experience servicing plans that already require spousal consent pushed back on the industry’s cost concerns. One said it uses the same recordkeeping platform for plans with and without spousal consent requirements — meaning the marginal cost is lower than critics suggest. Another, which services the TSP, said spousal consent adds as little as two hours to processing time for online requests. The TSP itself eliminated its notarization requirement in 2022 and saw no increase in fraud.
The Alternatives on the Table
Several stakeholders proposed middle-ground options:
Notification without consent. Spouses would be alerted when a participant requests to remove funds, but would have no formal power to block the transaction. The notice could include account balance information the spouse might not otherwise have. Critics note that notification alone doesn’t prevent the harm — it just means the spouse learns about it faster.
Digital account access. A spouse could be granted read-only access to view account balances and transaction history without any ability to modify or remove funds. This would address the information asymmetry that often underlies the problem.
Threshold-based consent. Spousal consent would be required only for withdrawals above a specified dollar threshold — proposals cited in the GAO report range from $3,500 to $5,000, or alternatively 25 percent of the account balance. Below the threshold, no consent would be required. This reduces administrative volume while preserving protection for large transactions.
Remote notarization. For plans that do require notarized spousal consent, allowing remote notarization services in lieu of in-person appointments reduces the friction considerably. The IRS has confirmed that remote notarization is available when participants make requests electronically.
Domestic violence exceptions. All stakeholders agreed that participants in abusive relationships should be able to access their own funds without triggering a consent requirement that would alert or require cooperation from an abusive spouse. The SECURE 2.0 Act created such an exception for private-sector plans; the TSP has not yet been amended to include one.
Where This Goes
The GAO report makes no legislative recommendations — its mandate was to describe the landscape, not prescribe a solution. But the fact that it was commissioned by senior members of the Senate’s HELP Committee signals that legislation is being considered. The policy menu is well-defined. The political will to act on it remains to be seen.
