Retirement accounts are split in divorce through court-ordered processes that divide only the portion of each account that accumulated during the marriage. Workplace plans like 401(k)s, 403(b)s, and pensions are divided by a specialized document called a Qualified Domestic Relations Order (QDRO). IRAs use a simpler mechanism called a transfer incident to divorce. Handled correctly, the money keeps its tax-deferred status and no one owes a penalty. Handled wrong, you can walk into an income tax bill plus a 10 percent early withdrawal penalty on money you were supposed to receive clean.
What Portion of the Account Is Actually Divisible
Not every dollar in a retirement account is on the table. Contributions and growth from before the marriage, and in most places from after the date of separation or filing, stay with the account holder as separate property. What accumulated in between is marital property.
Courts isolate that marital portion using a coverture fraction: years of plan participation during the marriage divided by total years of participation. If someone contributed to a 401(k) for 20 years and was married for 10 of them, roughly half the current balance enters the marital estate.
How that marital portion gets split depends on where you live. Community property states start from a 50/50 presumption. Most states follow equitable distribution, where a judge divides based on fairness considering earning capacity, length of the marriage, and each spouse’s needs. Equitable does not mean equal.
The QDRO for 401(k)s, 403(b)s, and Pensions
Workplace retirement plans are governed by the Employee Retirement Income Security Act of 1974 (ERISA). Under ERISA, a plan administrator cannot pay benefits to anyone other than the employee unless a court issues a Qualified Domestic Relations Order.1U.S. Department of Labor. FAQs about Retirement Plans and ERISA The QDRO is the only mechanism that bridges state divorce law and federal retirement regulations.
Federal law dictates what a QDRO must contain: the names and last known mailing addresses of the participant and the alternate payee (the former spouse), the amount or percentage to be paid, the number of payments or time period, and the name of each plan it applies to. A QDRO cannot require a plan to pay benefits it doesn’t otherwise offer, increase benefits beyond their actuarial value, or override a prior QDRO already in place.2Office of the Law Revision Counsel. 29 U.S. Code 1056 – Form and Payment of Benefits
Done correctly, a QDRO allows a direct transfer into the alternate payee’s own retirement account and preserves tax-deferred status. Without one, any distribution to a non-employee gets treated as a taxable withdrawal from the participant’s account, with income tax and potentially the 10 percent early withdrawal penalty attached.1U.S. Department of Labor. FAQs about Retirement Plans and ERISA
Separate Interest vs. Shared Payment
A QDRO has to say how the alternate payee receives their share. The two approaches work very differently.
The separate interest approach carves out an independent portion of the account for the alternate payee. With a 401(k), this usually means the alternate payee can receive an immediate rollover into their own account and manage it from there. Access timing depends on the plan’s terms, not on when the participant retires.3U.S. Department of Labor. QDROs Under ERISA – A Practical Guide to Dividing Retirement Benefits This is the cleaner break and the most common choice for 401(k)-type accounts.
The shared payment approach splits each retirement payment as it’s made. The alternate payee receives a percentage or dollar amount of every check the participant gets. This is more common with pensions already in pay status, and it carries a real risk: if the participant dies before retirement or never starts drawing benefits, the alternate payee gets nothing unless the QDRO separately addresses survivor benefits.3U.S. Department of Labor. QDROs Under ERISA – A Practical Guide to Dividing Retirement Benefits
For pensions where the future payout is hard to pin down, some couples use a present-value buyout. An actuary calculates the current cash worth of the future benefit, and one spouse offsets that value against another asset. One spouse keeps the pension; the other gets a larger share of the home equity or another account.
Dividing IRAs Without a QDRO
IRAs, including traditional, Roth, SEP, and SIMPLE accounts, are not governed by ERISA and cannot be divided by a QDRO. Plan administrators will reject a QDRO submitted for an IRA.4Internal Revenue Service. Publication 504 (2025) – Divorced or Separated Individuals IRAs are divided through a “transfer incident to divorce” under Section 408(d)(6) of the Internal Revenue Code.5Office of the Law Revision Counsel. 26 U.S. Code 408 – Individual Retirement Accounts
Under this provision, transferring all or part of an IRA to a former spouse under a divorce decree or written separation agreement is not a taxable event. Once transferred, the receiving spouse owns the account outright and bears full responsibility for any future taxes on withdrawals.4Internal Revenue Service. Publication 504 (2025) – Divorced or Separated Individuals The decree or agreement must specifically reference the transfer for the IRS to respect it.
Use a direct trustee-to-trustee transfer. Funds move straight from one institution to another without anyone writing a check. If you instead withdraw funds from your IRA and hand the money to your former spouse, the IRS treats that as your distribution. You owe income tax on the full amount, and if you’re under 59½, you face the 10 percent early withdrawal penalty on top of it.6Internal Revenue Service. Filing Taxes After Divorce or Separation This is one of the most expensive mistakes people make during divorce, and it’s entirely avoidable.
The Tax Trap Most People Miss
For workplace plans divided by QDRO, the alternate payee reports any distributions as their own income, not the participant’s.7Internal Revenue Service. Retirement Topics – QDRO Qualified Domestic Relations Order Roll the funds into your own IRA or qualified plan and no tax is due at transfer.
Here’s the detail worth knowing before you move the money. Distributions from a qualified plan made directly to an alternate payee under a QDRO are exempt from the 10 percent early withdrawal penalty, even if the alternate payee is under 59½.8Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions That exception vanishes the moment the money lands in an IRA. Once it’s in your IRA, any withdrawal before 59½ triggers the standard penalty.
So if you need some cash immediately, take a partial distribution directly from the 401(k) first and roll the rest into an IRA. Rolling everything first and then withdrawing costs you the penalty.
Roth accounts work differently in a property-offset negotiation. The receiving spouse inherits the tax-free withdrawal treatment for qualified distributions, and the original contribution basis and five-year rule age carry over. A $100,000 Roth is worth more in after-tax terms than a $100,000 traditional 401(k), and both spouses should account for that when splitting assets.
Military and Federal Government Plans Use Different Documents
If one spouse’s retirement is a military pension, a federal civilian pension, or the Thrift Savings Plan, a standard QDRO will be rejected. Each has its own paperwork.
Military pensions are divided under the Uniformed Services Former Spouses’ Protection Act. A state court can treat disposable military retired pay as marital property, but the total payable to a former spouse under all court orders cannot exceed 50 percent of disposable retired pay. The “10/10 rule” controls enforcement: if the marriage overlapped with at least 10 years of creditable military service, the Defense Finance and Accounting Service pays the former spouse directly. If not, the former spouse must collect from the service member instead.9Office of the Law Revision Counsel. 10 U.S. Code 1408 – Payment of Retired or Retainer Pay in Compliance With Court Orders
Federal employees under the Civil Service Retirement System (CSRS) or the Federal Employees Retirement System (FERS) need a “court order acceptable for processing” rather than a QDRO. The Office of Personnel Management will generally reject orders labeled as QDROs or submitted on ERISA forms unless the order explicitly states that its provisions are governed by Part 838 of Title 5 of the Code of Federal Regulations.10eCFR. 5 CFR Part 838 – Court Orders Affecting Retirement Benefits
The Thrift Savings Plan, available to military and federal civilian employees, requires a Retirement Benefits Court Order (RBCO) that meets TSP-specific requirements. The plan must be named as the “Thrift Savings Plan” exactly, the entitlement date cannot be in the future, and the order must state whether earnings and losses between the entitlement date and the transfer are included.11Thrift Savings Plan. Court Orders and Powers of Attorney
Survivor Benefits Have to Be Named Separately
Dividing the retirement benefit itself is only half the job. If the participant dies before or during retirement, the alternate payee can lose everything unless the QDRO explicitly addresses survivor benefits.
Federal law requires many defined benefit plans to offer a Qualified Preretirement Survivor Annuity (QPSA), which pays a monthly benefit to the surviving spouse if the participant dies before retirement. A QDRO can designate the former spouse as the recipient. When it does, any new spouse the participant later marries cannot be treated as the surviving spouse for that portion.12U.S. Department of Labor. QDROs – The Division of Retirement Benefits Through Qualified Domestic Relations Orders
Both the divorce decree and the QDRO should clearly state that survivor benefits go to the alternate payee. Vague language invites disputes. If the plan has a one-year marriage requirement before it recognizes a spouse for survivor benefit purposes, the QDRO cannot override that for marriages shorter than one year.12U.S. Department of Labor. QDROs – The Division of Retirement Benefits Through Qualified Domestic Relations Orders Check with the plan administrator before the divorce is finalized.
Getting the Order Signed and Executed
The sequence matters. Skipping steps leads to delays or rejection.
- Submit a draft to the plan administrator first. Most offer a preliminary review to confirm the order is compatible with the plan’s terms. This catches problems before the court is involved.
- Get the court’s signature as part of the divorce proceedings once the administrator approves the draft.
- Obtain a certified copy from the court clerk after the judge signs.
- Deliver the certified copy to the plan administrator, who then qualifies the order, sets up a separate account for the alternate payee or processes a distribution, and notifies both parties.1U.S. Department of Labor. FAQs about Retirement Plans and ERISA
Processing times vary, but most administrators complete the transfer within 30 to 90 days after receiving the certified order. During this determination period, the plan may temporarily freeze the participant’s account to prevent distributions that would reduce the alternate payee’s share. If you have reason to believe your spouse might liquidate retirement funds before the QDRO is in place, ask your attorney about a temporary restraining order or an automatic standing order early in the proceedings. Many jurisdictions issue these routinely at the start of a case.
One more detail. If the QDRO awards a fixed dollar amount rather than a percentage, the order should specify whether investment gains and losses between the award date and the actual transfer apply to that amount. Markets can move significantly during the months a QDRO is being processed. Failing to address this leaves money on the table or creates a dispute over a shortfall.12U.S. Department of Labor. QDROs – The Division of Retirement Benefits Through Qualified Domestic Relations Orders A percentage award adjusts with the market automatically.
Don’t let the QDRO fall through the cracks after the divorce is finalized. It’s surprisingly common for couples to sign a settlement agreement that calls for a QDRO and never actually draft or file one. Years later, the alternate payee discovers they have no enforceable claim on the account. Treat the QDRO as an immediate post-divorce action item.
