In almost every ordinary lawsuit, you cannot lose your 401(k). Federal law shields money held inside an employer-sponsored 401(k) plan from judgment creditors, so a civil verdict for a car accident, unpaid credit card, medical bill, or breached contract cannot reach the balance while it sits in the plan. The shield has real exceptions — divorce and support orders, unpaid federal taxes, and federal criminal restitution — and it disappears the moment you take the money out.
Why Ordinary Civil Judgments Cannot Reach Your 401(k)
The protection comes from the Employee Retirement Income Security Act of 1974 (ERISA). Every pension plan governed by ERISA must include a rule preventing benefits from being assigned to or seized by outside parties.1Office of the Law Revision Counsel. 29 U.S. Code 1056 – Form and Payment of Benefits Because ERISA is federal, it overrides conflicting state laws and gives you the same shield regardless of where you live. A judgment creditor who wins a civil suit against you cannot garnish or attach your 401(k) balance while it remains in the plan.
The same protection extends to profit-sharing plans, defined benefit pensions, and most 403(b) plans offered by private employers. It also follows you into bankruptcy. The Supreme Court held in Patterson v. Shumate that ERISA’s anti-alienation rule keeps 401(k) assets out of the bankruptcy estate, giving them unlimited protection if you file.2Legal Information Institute. Patterson v. Shumate, 504 U.S. 753 (1992)
The Exceptions That Can Reach a 401(k)
A short list of claims can get past ERISA’s shield. If one of these applies to you, the fact that the money is in a 401(k) will not stop collection.
Divorce, Child Support, and Alimony
The largest exception involves family law. A court handling a divorce, separation, or support dispute can issue a Qualified Domestic Relations Order (QDRO) directing the plan to pay a portion of your benefits to a spouse, former spouse, child, or other dependent.1Office of the Law Revision Counsel. 29 U.S. Code 1056 – Form and Payment of Benefits Once a valid QDRO is in place, the plan administrator must comply with it, and the anti-alienation rule steps aside. QDROs are used both to divide marital property in a divorce and to enforce ongoing child support or alimony.3Internal Revenue Service. Retirement Topics – QDRO: Qualified Domestic Relations Order
To qualify, the order must identify the participant and alternate payee, state the dollar amount or percentage assigned, name the time period covered, and specify the plan.4U.S. Department of Labor. Qualified Domestic Relations Orders Under ERISA: A Practical Guide to Dividing Retirement Benefits An order missing any of those elements can be rejected by the plan administrator.
Unpaid Federal Taxes
The IRS is not bound by ERISA’s anti-alienation rule. If you owe unpaid federal taxes, the IRS can levy your 401(k) to collect.5Office of the Law Revision Counsel. 26 U.S. Code 6331 – Levy and Distraint The agency must first send a tax bill, a formal demand for payment, and a written notice of intent to levy at least 30 days before taking action, and that notice tells you about your right to a Collection Due Process hearing.6Internal Revenue Service. 5.17.3 Levy and Sale
There is one meaningful limit: the IRS can only reach funds you are currently eligible to withdraw. If plan rules bar you from taking distributions because you are still employed and under the plan’s distribution age, the IRS cannot force the plan to override those restrictions. The amount seized is still taxable income, but a distribution caused by an IRS levy is exempt from the 10% early withdrawal penalty that otherwise applies to people under age 59½.7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
Federal Criminal Restitution
If you are convicted of a federal crime and ordered to pay restitution to victims, the government can enforce that order against your property “notwithstanding any other Federal law.”8Office of the Law Revision Counsel. 18 U.S. Code 3613 – Civil Remedies for Satisfaction of an Unpaid Fine Courts have read that language to override ERISA, so the government can garnish 401(k) funds to compensate victims of federal fraud, embezzlement, and similar offenses. A private party suing you in civil court cannot invoke this statute; it applies only in federal criminal sentencing.
How You Can Lose the Protection Yourself
ERISA protects benefits inside the plan. The protection depends on the money staying there, and two common moves end it.
The first is a distribution. The moment you take money out of the 401(k) and deposit it in a personal checking or savings account, those funds become ordinary assets that a judgment creditor can garnish or levy. The same thing happens if you take a plan loan and default on it, which triggers a deemed distribution. If you are facing a lawsuit or expecting a judgment, pulling money out of your 401(k) to “protect” it accomplishes the opposite — leaving the money in the plan is what keeps it shielded.
The second is a rollover to an IRA. IRAs are not governed by ERISA, so the federal shield that covers your 401(k) does not travel with the money.
In bankruptcy, Traditional and Roth IRAs are protected only up to $1,711,975 (adjusted for inflation as of April 2025) on amounts you contributed directly.9Office of the Law Revision Counsel. 11 U.S. Code 522 – Exemptions Dollars rolled over from a 401(k) and their earnings are exempt without a cap, but only if you can prove which dollars came from the employer plan — a reason to keep rollover funds in a separate IRA from your regular contributions.
Outside of bankruptcy, IRA protection against a civil judgment depends entirely on your state’s laws, and the range is wide. Some states offer unlimited protection, some limit it to amounts reasonably necessary for retirement, and a few provide little or none. Many carve out exceptions for support obligations or recent contributions. If you live in a state with weak IRA protections and face any litigation risk, think carefully before rolling over a 401(k).
If Your Plan Is Not a Standard Employer 401(k)
Not every retirement account carries the full ERISA shield. A few situations worth knowing about:
- Solo 401(k) plans. A plan covering only a business owner and possibly their spouse follows the same tax rules as any other 401(k), but it is generally exempt from ERISA’s Title I requirements because the owner is not a common-law employee. Creditor protection in a non-bankruptcy lawsuit then depends on state law.10Internal Revenue Service. One-Participant 401k Plans
- 403(b) and 457 plans. Most 403(b) plans at private nonprofits are ERISA-governed and get the same shield as a 401(k). Plans sponsored by public schools, government entities, and churches, along with governmental 457(b) plans, are outside ERISA. They may still receive protection under state law or plan terms, but that protection is less uniform.
- Inherited 401(k) accounts. If you inherit a 401(k) and leave the funds inside the plan under the administrator’s control, those assets generally keep their ERISA protection. A bankruptcy court reached this result in In re Dockins (2021), on the condition that the beneficiary had not already withdrawn the money. Inherited IRAs are a different story: the Supreme Court held unanimously in Clark v. Rameker that they are not “retirement funds” for purposes of the federal bankruptcy exemption.11Justia U.S. Supreme Court Center. Clark v. Rameker, 573 U.S. 122 (2014)
For an ordinary civil lawsuit against the typical employee with a standard 401(k) through work, the answer is reassuring: the money stays where it is, and the creditor does not get it. The exceptions matter, but they are specific, and they do not include the kinds of lawsuits most people worry about.
