The ERISA anti-alienation rule bars private creditors from seizing money held in an employer-sponsored retirement plan. It requires every covered pension plan to state that your benefits cannot be assigned or transferred away, and it is codified at 29 U.S.C. § 1056(d)(1).1Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits The protection is unusually strong, but it is not absolute. Divorce courts, the IRS, federal criminal judgments, and the plan itself can all reach past it under the right conditions.
What the Rule Blocks
The rule cuts in two directions. You cannot voluntarily hand your future benefits to someone else, and outsiders cannot take them by legal force. You cannot pledge a 401(k) balance as collateral for a car loan or a credit card. If a creditor wins a judgment against you for hundreds of thousands of dollars, they still cannot compel the plan administrator to pay out your retirement money to satisfy that debt.2Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits
A standard garnishment order that works against a bank account or paycheck is useless against an ERISA-qualified plan. The plan administrator is required to refuse it. A creditor who can drain your savings, put a lien on your house, and garnish your wages hits a wall when they reach your 401(k).
Which Plans Are Covered
The rule applies to plans that qualify under both ERISA and Section 401(a)(13) of the Internal Revenue Code. That means 401(k) plans, traditional defined benefit pensions, and profit-sharing plans sponsored by private employers.3Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans If your employer set up the plan and it holds assets in trust for your benefit, you almost certainly have this protection.
Several common retirement vehicles sit outside the rule. Individual Retirement Accounts and SEP IRAs are not ERISA-covered, so they do not carry the federal anti-alienation mandate. Some state laws shield IRAs from creditors to varying degrees, but that patchwork is a different thing from the uniform federal barrier ERISA provides. The distinction matters most when deciding whether to roll an old 401(k) into an IRA after leaving a job.
Government retirement plans and church plans are also exempt from ERISA’s requirements.4Office of the Law Revision Counsel. 29 USC 1003 – Coverage Federal, state, and local pension systems, along with 457(b) deferred compensation plans offered by government employers, operate under their own rules. Any creditor protection there comes from separate statutes, not from ERISA.
The Built-In Exceptions
The statute itself allows two controlled forms of flexibility. If your plan offers participant loans, you can borrow against your own vested balance and use that balance as security for the loan. The loan has to meet the requirements for an exempt prohibited transaction under the tax code, which in practice means it follows the plan’s loan terms, carries a reasonable interest rate, and is repaid on schedule.2Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits
Once you are receiving benefit payments, you can also voluntarily direct up to 10% of each payment to someone else, as long as the assignment is revocable and is not being used to cover plan administrative costs.2Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits The word “voluntary” is doing real work here. A court order or a creditor demand does not qualify.
Divorce and QDROs
Divorce is the clearest exception. A Qualified Domestic Relations Order lets a state court divide retirement plan benefits between spouses as part of a divorce, legal separation, or child support arrangement. Without a QDRO, the plan administrator must refuse to pay benefits to anyone other than the participant, even if a divorce decree says otherwise.5Internal Revenue Service. Retirement Topics – Qualified Domestic Relations Order
A valid QDRO has to identify the participant and each alternate payee, the plan it applies to, and how much the alternate payee receives, whether by dollar amount, percentage, or formula. It also cannot require the plan to pay out a type of benefit the plan does not offer. A QDRO directing a 401(k) to provide a life annuity would be rejected if that plan only makes lump-sum distributions.6Department of Labor. QDROs Under ERISA – A Practical Guide to Dividing Retirement Benefits Plan administrators may charge processing fees, which federal law allows to be assessed as reasonable expenses against the participant’s account.
Bankruptcy
If you file for bankruptcy, your ERISA-qualified retirement assets stay out of the bankruptcy estate. The Bankruptcy Code provides that a restriction on transferring a beneficial interest in a trust remains enforceable if it is valid under other federal or state law.7Office of the Law Revision Counsel. 11 USC 541 – Property of the Estate The Supreme Court held in Patterson v. Shumate that ERISA’s anti-alienation provision is exactly that kind of restriction, so 401(k) and pension funds are excluded from the pool of assets available to pay creditors in bankruptcy.8Justia Law. Patterson v Shumate, 504 US 753 (1992)
This protection has no dollar cap. IRA protections in bankruptcy are limited under federal law; ERISA plan assets are fully excluded regardless of size. A participant with $2 million in a 401(k) receives the same complete protection as someone with $20,000. For people carrying significant debt, the difference between an ERISA-qualified plan and an IRA can be the single biggest factor in what they keep.
IRS Tax Levies
The IRS can reach an ERISA-protected plan in a way no private creditor can. Under 26 U.S.C. § 6331, if you owe federal taxes and fail to pay within ten days of a notice and demand, the IRS has authority to levy against all of your property and rights to property, retirement accounts included.9Office of the Law Revision Counsel. 26 USC 6331 – Levy and Distraint The anti-alienation rule does not apply to federal tax collection.
In practice, the IRS treats retirement levies as a last resort. Internal policy requires revenue officers to determine that the taxpayer has engaged in “flagrant conduct” before levying on a retirement account.10Internal Revenue Service. IRM 5.11.6 Notice of Levy in Special Cases That covers behavior like tax evasion, hiding assets, or continuing voluntary retirement contributions while claiming an inability to pay. If none of that applies, the IRS generally will not touch your retirement account even though it legally could. That restraint is a policy choice, not a legal guarantee.
Criminal Fines and Restitution
Federal criminal restitution orders can reach a retirement plan the same way a tax levy can. Under 18 U.S.C. § 3613, a federal court can enforce a fine or restitution order against “all property or rights to property” of the defendant, and the statute opens with “Notwithstanding any other Federal law,” which overrides ERISA’s protection.11Office of the Law Revision Counsel. 18 USC 3613 – Civil Remedies for Satisfaction of an Unpaid Fine The Mandatory Victims Restitution Act requires courts to order restitution when sentencing defendants convicted of certain crimes, and § 3613’s enforcement provisions apply to those orders.12Office of the Law Revision Counsel. 18 USC 3663A – Mandatory Restitution to Victims of Certain Crimes
The list of property exempt from these enforcement actions is narrow. It mirrors certain IRS levy exemptions for basic necessities, but retirement accounts are not among the exempt categories. In fraud cases and other white-collar prosecutions, defendants routinely lose their entire retirement balances to restitution orders.
Fiduciary Breach and Plan-Related Crimes
A less obvious exception applies when you owe money back to your own plan. If a court finds that you committed a crime involving the plan or violated your fiduciary duties to it, the plan can offset what you owe against your own benefits. The judgment or settlement has to specifically authorize the offset. If the plan provides survivor annuities, your spouse’s rights get added protection: in most cases the spouse must consent to the offset in writing, or must have been part of the underlying violation.2Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits
The exception targets people in positions of trust over the plan. A company executive who embezzles from the pension fund cannot hide behind the anti-alienation rule when the plan seeks repayment from their own account. The same applies to settlements with the Department of Labor or the Pension Benefit Guaranty Corporation over fiduciary violations.
When Protection Ends: Money That Leaves the Plan
This is where people get tripped up. The rule protects funds held inside a qualified plan. Once you take a distribution and deposit the money into a personal checking or savings account, that federal protection largely disappears. Multiple federal appeals courts have held that the anti-alienation rule applies only to undistributed funds, and that creditors are free to pursue retirement money once the participant has received it.
The practical consequence is significant. A creditor who could not touch your 401(k) while it sat in the plan can garnish the same dollars the moment they land in your bank account. State law then determines what happens next, and the protections vary enormously. Some states shield distributed retirement funds if you keep them in a separate, traceable account. Others offer little or nothing once the money is commingled.
Rolling distributed funds into another ERISA-qualified plan preserves the protection. A direct rollover into a new employer’s 401(k) does the same. Rolling into an IRA may downgrade your protection to whatever your state provides, which could be substantially less. If you are facing creditor issues or anticipate litigation, the difference between a direct plan-to-plan transfer and a distribution you deposit personally is one of the most consequential financial decisions you can make.
