Dividing retirement accounts in a divorce
The retirement accounts are usually worth more than the house and are the thing most often got wrong, because a 401(k) and an IRA are split under different statutes and only one of them lets you reach the cash without a penalty.
Almost everything here is federal, which means it works the same way in every state. That makes it unusually checkable, and it is why the sections below quote the statute rather than paraphrasing it.
1. Why the plan will not just do what your decree says
A qualified retirement plan is forbidden by law from paying your share to you. 26 U.S.C. § 401(a)(13)(A):
“A trust shall not constitute a qualified trust under this section unless the plan of which such trust is a part provides that benefits provided under the plan may not be assigned or alienated.”
That is the anti-alienation rule, and it exists to stop creditors reaching pensions. A QDRO is the narrow exception carved into it. So when a plan administrator returns your divorce decree unpaid, they are not being obstructive — complying would disqualify the plan.

Your decree is probably not a QDRO
§ 414(p)(1)(A) defines a qualified domestic relations order as one that “creates or recognizes the existence of an alternate payee’s right to, or assigns to an alternate payee the right to, receive all or a portion of the benefits payable with respect to a participant under a plan” and that satisfies the detailed requirements of § 414(p)(2) and (3).
A decree that says “the wife shall receive one half of the husband’s 401(k)” normally names no plan, no dollar amount or percentage, no number of payments and no period, so it fails those requirements. The QDRO is a separate document, drafted after the decree, and the plan reviews it before a court signs it. Many plans will pre-approve a draft, which is worth asking for, because it is far cheaper than fixing a rejected order afterwards.
2. An IRA is not divided by a QDRO, and paying for one is wasted money
An IRA is not a qualified plan. It is divided under a different section entirely. 26 U.S.C. § 408(d)(6):
“The transfer of an individual’s interest in an individual retirement account or an individual retirement annuity to his spouse or former spouse under a divorce or separation instrument described in clause (i) of section 121(d)(3)(C) is not to be considered a taxable transfer made by such individual … and such interest at the time of the transfer is to be treated as an individual retirement account of such spouse.”
Note where that points: the same “divorce or separation instrument” definition used by the principal-residence rule on the house page. The paperwork has to exist and say so.
The mistake that costs real money is doing it yourself. If you withdraw from your IRA and hand your ex the cash, that is a distribution to you, taxed to you, whatever the decree says. It has to move by trustee-to-trustee transfer.

3. The one that almost nobody is told
The 10% early-withdrawal penalty is waived for a QDRO distribution — and then un-waived for IRAs. § 72(t)(2)(C) creates the exception for payments to an alternate payee under a qualified domestic relations order. § 72(t)(3)(A) then removes it again: “Subparagraphs (A)(v) and (C) of paragraph (2) shall not apply to distributions from an individual retirement plan.”
So the same dollar can come out of a 401(k) penalty-free under the order and cost you 10% coming out of an IRA. And it is one-way: roll the QDRO money into an IRA for safekeeping and the exception is gone for good.
The full working, with the statute quoted
The subsection quoted in full, the interaction with § 408(d)(1), the sources it was read from, and a list of what is published everywhere about QDROs and is wrong, are on dividing retirement: QDROs, IRAs and pensions. If you are deciding whether to take the money or roll it, read that before you decide.
4. A retirement dollar is not a cash dollar
| What you take | Tax already paid? | What it means in a settlement |
|---|---|---|
| Traditional 401(k) or IRA | No — pre-tax | Ordinary income tax is due when it comes out. A $200,000 balance is not $200,000 to you. |
| Roth 401(k) or Roth IRA | Yes | Qualified withdrawals come out tax-free, so a Roth dollar is worth more than a traditional dollar of the same face value. |
| Taxable brokerage account | Partly | Tax is owed only on the gain, and the basis carries over under § 1041(b)(2), so ask what the basis is. |
| Cash | Yes | Face value is real value. |
Splitting “the 401(k) to you, the savings to me” down the middle at face value is not an even split, and it is one of the most common reasons a settlement that looked fair turns out not to have been. What the difference is worth depends on your bracket and when the money comes out, which is a calculation for your own figures.
5. The part that gets forgotten after the decree
Until the plan has an approved order, the account is still theirs
The QDRO is usually the last item on the list and it is the one most often left undone. Until the plan has approved and implemented the order, the participant can take a loan against the balance, change jobs and roll it somewhere else, or die with a beneficiary form naming somebody who is not you.
A decree saying you are owed half is a claim against a person. A QDRO is a claim on an account. They are not the same thing, and the gap between them is where this goes wrong.
Two things worth doing in the same week as the decree: ask the plan for its written QDRO procedures, which it must give you, and start the draft. And separately — check the beneficiary forms, because the form beats the will and the decree on a retirement account, and that is a different failure with the same ending.
Where this sits alongside the rest
Selling the house in a divorce covers the other large asset and the two tax rules that decide what it is worth. Know what you own is the inventory to do first, before any of this is negotiable. Beneficiary forms is the thirty-minute job that undoes the most damage for the least effort.
Common questions
What is a QDRO, in plain words?
A court order that tells a retirement plan to pay part of one spouse’s benefit to the other. It is needed because federal law otherwise forbids the plan from doing it. 26 U.S.C. § 401(a)(13)(A) says a plan is not a qualified plan at all “unless the plan of which such trust is a part provides that benefits provided under the plan may not be assigned or alienated.” A QDRO is the narrow exception. Without one the plan administrator is not being difficult when they refuse your decree — they are not allowed to comply with it.
Does my divorce decree count as a QDRO?
Usually not on its own. § 414(p)(1)(A) requires an order that “creates or recognizes the existence of an alternate payee’s right to, or assigns to an alternate payee the right to, receive all or a portion of the benefits payable with respect to a participant under a plan” AND meets the detailed requirements of § 414(p)(2) and (3). A decree that says “wife shall receive half of husband’s 401(k)” typically names no plan, no amount or percentage, no number of payments and no period — so the administrator rejects it. The QDRO is a separate document, drafted after the decree, and the plan reviews it.
Do I need a QDRO to divide an IRA?
No, and paying for one is a common waste of money. An IRA is not a qualified plan and is divided under 26 U.S.C. § 408(d)(6) instead: “The transfer of an individual’s interest in an individual retirement account or an individual retirement annuity to his spouse or former spouse under a divorce or separation instrument … is not to be considered a taxable transfer.” It is done by trustee-to-trustee transfer on the strength of the decree or agreement. What you must not do is withdraw the money and hand it over — that is a distribution to you, taxed to you.
Can I take cash out of a 401(k) split without the 10% penalty?
Once, and only at the moment of the split. 26 U.S.C. § 72(t)(2)(C) exempts from the 10% additional tax “any distribution to an alternate payee pursuant to a qualified domestic relations order.” You still owe ordinary income tax on it, but not the extra 10%. If you roll the money into your own IRA first and then withdraw it, the exception is gone — it attaches to the distribution made under the QDRO, not to the money forever.
Does that same 10% exception apply to an IRA split?
No, and this is the asymmetry that costs people the most. 26 U.S.C. § 72(t)(3)(A): “Subparagraphs (A)(v) and (C) of paragraph (2) shall not apply to distributions from an individual retirement plan.” Subparagraph (C) is the QDRO exception. So the spouse who takes $100,000 from a 401(k) under a QDRO and needs some of it in cash can reach it without the 10%; the spouse who takes $100,000 from an IRA cannot. Same money, same divorce, different statute.
Is a 401(k) worth the same as cash in a settlement?
No. A dollar in a traditional 401(k) or IRA is a pre-tax dollar and will be taxed as ordinary income when it comes out; a dollar in a taxable account or a checking account has already been taxed. Trading one for the other at face value hands one spouse a future tax bill and the other none. A Roth account is different again, because the tax has already been paid. This is arithmetic on your own figures and your own bracket, and it is a question for a tax professional before the agreement is signed.
How long does a QDRO take, and who pays for it?
Longer than people expect, because it is a sequence: the order is drafted, the plan reviews it (many plans will pre-approve a draft, which is worth asking for), the court signs it, the signed order goes back to the plan, and only then is the account segregated. Months is normal. Who pays is a term of your settlement, so it is worth deciding explicitly rather than discovering it later. The plan’s own QDRO procedures must be provided to you free on request.
What happens if nobody does the QDRO after the divorce?
The risk sits entirely with the spouse who was supposed to receive the money. Until the plan has an approved order, the account is the participant’s; they can take loans against it, change jobs and roll it over, or die with a beneficiary form naming somebody else. A decree saying you are owed half is a claim against a person, not a claim on an account. Do not leave it as the last item on the list.

If your name is on a joint account, the lender can still pursue you whatever the decree says — and a hold-harmless clause can be discharged in a Chapter 13 bankruptcy, because § 1328(a)(2) carries § 523(a)(5) across and leaves § 523(a)(15) behind. Debt in a divorce.
For every other reason a person loses coverage, the employer has to notify the plan.
