What Happens to Your Ex's Retirement Account in a Divorce?

If you're recently divorced and not sure what to do with your ex's retirement account, you're not alone. This is one of the most common questions I hear, and it doesn't go away just because the divorce is final. I regularly talk to people who've been divorced for over a year and still haven't moved their share of a 401(k), IRA, or pension into their own name.

Here's what happens to your ex's retirement account after a divorce: how 401(k)s, IRAs, and pensions each get divided, whether you need a QDRO, and what to do with the money once it's yours.

Splitting a 401(k) in Divorce: Rules, Taxes, and Penalties

If you're set to receive part of an ex's 401(k), start here: has the Qualified Domestic Relations Order (QDRO) been filed? A QDRO is the document that legally authorizes the plan to pay out your share, and not following up on it is one of the biggest mistakes I see people make after a divorce. I encourage clients to have the QDRO drafted before their final court appearance whenever possible, so a judge can sign it and it can go to the plan administrator right away. Every plan has its own QDRO requirements, so check with the plan directly to confirm what they need.

Once your QDRO is accepted, the plan administrator sends a letter asking how you want your funds distributed. Your options typically include keeping an account at the current firm, rolling the funds into an IRA, or taking a cash distribution. Each choice has different tax consequences, so this isn't a form to fill out on autopilot. I always ask clients to loop me in when this letter shows up, because a simple mistake here can be costly.

If you take a cash distribution directly from a 401(k) under a QDRO, you can generally avoid the 10% early withdrawal penalty even if you're under 591⁄2, though the money is still taxed as ordinary income. If the form never gets filled out and the plan cuts you a check instead, they're required to withhold 20% for federal taxes, and depending on your income, that can leave you with a real tax bill you didn't see coming.

You can also usually choose to keep your share of the 401(k) as its own account instead of rolling it into an IRA, though I generally don't recommend it. A 401(k) is built around employees, so non-employee participants don't get the same benefits, like the ability to take a loan against the account. The main upside to keeping it in place is access to investments only available to employees of that company. Rolling it into an IRA in your name usually means more investment options and more control over the funds.

How IRAs and Pensions Are Divided Between Ex-Spouses

IRAs work differently than 401(k)s. A QDRO isn't required to divide most IRAs and Roth IRAs. Instead, you'll typically submit a transfer form to the financial institution, and you may need to open a new account in your name if you don't already have one. There are exceptions, so confirm with the institution what documentation they require, and get it handled as part of the divorce process rather than after the fact. It's almost always easier to get these forms signed while the divorce is still open.

Pensions are their own category, and whether you're entitled to a share, and how that share gets calculated, depends on whether the pension is treated as a shared interest or a separate interest in your settlement. If a pension is part of what you're dividing, Dividing Pensions in a Divorce: Shared vs. Separate Interest walks through how that distinction affects what you receive.

Step-by-Step: How to Claim Your Share of Retirement Assets

1. Confirm your QDRO or transfer paperwork has been filed and accepted. Nothing else moves until this step is done.
2. Decide how you want the funds distributed once the plan sends you the option letter: keep the account where it is, roll it into an IRA, or take a cash distribution.
3. Weigh your time horizon. If you won't need the money for another 10, 20, or 30 years, that should shape how it's invested.
4. Check your tolerance for market volatility. Your comfort with risk is likely different from your ex's, and the strategy already in place was built for both of you, not just you. Dividing Investment Accounts in Divorce: What You Need to Know covers this in more depth.
5. Loop in a CDFA or financial advisor before you sign anything. A Certified Divorce Financial Analyst (CDFA) works with clients on exactly this kind of asset transfer, and a trusted financial advisor can help you build an investment strategy once the funds are yours, especially if investing is new to you.

Do You Need a QDRO to Divide an Ex's Retirement Plan?

It depends on the account. Employer-sponsored plans like 401(k)s and most pensions require a QDRO before the plan will pay out your share. Most IRAs don't, though there are exceptions worth confirming with your specific institution. If you haven't already, learn more about QDRO processing, including what it costs and how long it typically takes.

How is a pension divided in a divorce? Most pensions are divided using a QDRO or a similar plan-specific order that sets out what percentage or dollar amount goes to each spouse, and when. The calculation depends on whether the pension is a shared or separate interest, and whether you're pulling from a benefit already being paid or one still accruing. How to Keep Your Pension in a Divorce covers what to weigh if you're deciding whether to keep it.
