Your retirement savings may represent years of hard work, but what happens to those funds when your marriage ends? In Illinois, retirement accounts and pensions earned during the marriage are generally presumed marital property under 750 ILCS 5/503(b)(2). However, dividing these assets does not always mean splitting them equally, and certain premarital or inherited funds may be protected.
At Caesar & Bender, LLP, Chicago property division attorneys Michael Ian Bender and Molly E. Caesar help clients address retirement accounts and pension divisions during divorce in Illinois. Our team assists with identifying marital and non-marital portions of retirement assets and evaluating options for dividing them.
This guide explains how Illinois courts classify and divide retirement assets, when a QDRO or QILDRO is required, and how valuation, taxes, dissipation, and survivor benefits can affect the outcome. Call Caesar & Bender, LLP at (312) 236-1500 to schedule a consultation.
Are Retirement Accounts Marital Property in Illinois?
Under the Illinois Marriage and Dissolution of Marriage Act (IMDMA), 750 ILCS 5/503(b)(2), retirement benefits acquired during marriage are presumed marital property, regardless of whose name is on the account. However, retirement assets can also include non-marital funds, such as contributions made before marriage or assets received through inheritance, which are treated differently during property division.
Marital and Non-Marital Portions
A retirement account can contain both marital and non-marital funds, making it important to identify when contributions were made and how their value changed over time. Contributions and investment earnings accumulated during marriage are typically marital property, while premarital contributions and their traceable growth can remain separate.
For example, if an account held $40,000 before marriage and increased to $400,000, the court must distinguish the growth attributable to the original balance from contributions and earnings accumulated during marriage.
Premarital Accounts, Commingling, and Tracing
To establish that retirement funds are non-marital, a spouse must provide evidence showing where the funds originated and how their value changed. Account statements, contribution records, and other financial documents help trace these amounts, particularly when marital and non-marital funds have been combined.
Under 750 ILCS 5/503(c), the treatment of commingled funds depends on whether the original contributions can still be identified. Reimbursement between marital and non-marital estates is possible when contributions are traced by clear and convincing evidence and were not intended as gifts.
Inherited Funds and Marital Agreements
Retirement assets received through inheritance or as gifts are also treated differently from funds accumulated during marriage. Under 750 ILCS 5/503(a)(1), inherited property is classified as non-marital, so an inherited IRA held separately can remain outside the marital estate if its non-marital character is preserved. Similarly, Section 503(a)(4) recognizes property excluded through a valid marital agreement, provided the agreement is enforceable.
How Does Illinois Divide Retirement Accounts in a Divorce?
Illinois follows equitable distribution, meaning retirement accounts and other marital property are divided fairly rather than automatically split 50/50. Under 750 ILCS 5/503(d), courts divide marital property in “just proportions” based on several factors, including each spouse’s financial circumstances, contributions to the marriage, and future financial needs.
Statutory Factors the Court Considers
When determining how to divide retirement assets, Illinois courts consider the following factors under Section 503(d):
- Contributions (Section 503(d)(1)): Financial support, homemaking, childcare, and efforts to acquire or preserve property.
- Dissipation (Section 503(d)(2)): Improper spending of marital assets during the breakdown of the marriage.
- Property Value (Section 503(d)(3)): The value of assets awarded to each spouse.
- Duration (Section 503(d)(4)): The length of the marriage.
- Economic Circumstances (Section 503(d)(5)): Each spouse’s financial position when the division takes effect.
- Personal Circumstances (Section 503(d)(8)): Age, health, employment, income, liabilities, and financial needs.
- Future Earning Potential (Section 503(d)(11)): Opportunities to earn income and acquire assets.
- Tax Consequences (Section 503(d)(12)): The tax impact of the property division.
Offsets and Negotiated Settlements
Retirement accounts do not always need to be divided directly between spouses. Under 750 ILCS 5/502, spouses can negotiate a marital settlement agreement that divides retirement assets alongside other marital property, allowing them to balance the overall distribution.
For example, one spouse can retain their pension while the other receives a larger share of the marital home’s equity. Under Section 502(b), the court is bound by the property settlement terms unless it finds them unconscionable. In Cook County, the Domestic Relations Division reviews the agreement before incorporating it into the divorce judgment.
Which Types of Retirement Accounts Are Divided in Illinois?
Different retirement accounts follow different rules during an Illinois divorce. While the marital portion of 401(k)s, IRAs, pensions, and other retirement benefits is subject to equitable distribution, the process depends on the type of plan and the laws governing it.
| Account Type | Plan Category | Division Order | How Division Works |
|---|---|---|---|
| 401(k) | Defined contribution | QDRO | Marital portion allocated to the alternate payee |
| 403(b) | Defined contribution | QDRO for ERISA-covered plans; other orders for exempt plans | Depends on the employer, plan terms, and applicable law |
| Traditional IRA | Individual account | No QDRO; transfer incident to divorce | Direct transfer between IRA custodians |
| Roth IRA | Individual account | No QDRO; transfer incident to divorce | Direct transfer subject to Roth IRA tax rules |
| Private Employer Pension | Defined benefit | QDRO | Present value buyout or division of future payments |
| Illinois State or Municipal Pension | Defined benefit | QILDRO | Division under the Illinois Pension Code |
| Military Retirement | Defined benefit | Military retirement division order | Division under applicable federal military retirement rules |
| 457 Deferred Compensation | Deferred compensation | Plan-specific domestic relations order | Requirements differ for governmental and nongovernmental plans |
401(k)s, 403(b)s, and Other Defined Contribution Plans
Defined contribution plans, including 401(k)s and 403(b)s, are valued using their account balances on the applicable valuation date. The marital portion includes contributions made during the marriage and the investment gains or losses attributable to those contributions. For ERISA-covered plans, a Qualified Domestic Relations Order (QDRO) directs the plan administrator to allocate the non-employee spouse’s share, either through a separate account or another method permitted by the plan. Governmental 403(b) and 457 plans follow their own division requirements.
IRAs and Transfers Incident to Divorce
Unlike employer-sponsored retirement plans, traditional and Roth IRAs do not require a QDRO because they are not governed by the Employee Retirement Income Security Act (ERISA). Instead, the account interest is transferred under Internal Revenue Code Section 408(d)(6), using a divorce or separate maintenance decree or a written instrument incident to it. When completed through a qualifying transfer, the transaction does not create an immediate tax liability.
Private Pensions and Defined Benefit Plans
Defined benefit pensions provide retirement payments based on factors such as salary history and years of service. These benefits can be divided through a present value buyout or by allocating a portion of future pension payments to the non-employee spouse.
For a buyout, a financial professional or actuary calculates the present value of the pension, allowing the other spouse to receive an offset through marital assets or an agreed payment. Alternatively, the court can retain jurisdiction to divide pension payments when they become payable. The pension’s benefit formula, retirement options, and plan provisions affect the amount awarded.
Military and Federal Retirement
Military retirement benefits are subject to the Uniformed Services Former Spouses’ Protection Act, 10 U.S.C. 1408, which permits state courts to divide disposable military retired pay as marital property. Direct payments from the Defense Finance and Accounting Service require at least 10 years of marriage overlapping with 10 years of creditable military service. This 10/10 rule governs eligibility for direct payment, not the court’s authority to divide military retirement benefits.
Federal civilian retirement benefits follow a separate process. Instead of a standard QDRO, the division requires a court order acceptable for processing by the Office of Personnel Management under applicable federal regulations.
Social Security Benefits
Unlike retirement accounts and pensions, Social Security benefits cannot be divided as marital property in an Illinois divorce. Under 42 U.S.C. 407(a), federal law restricts the assignment or transfer of these benefits. In In re Marriage of Crook, the Illinois Supreme Court also ruled that courts cannot use anticipated Social Security benefits to offset the division of other marital assets.
However, a former spouse can qualify for divorced spouse benefits through the Social Security Administration if the marriage lasted at least 10 years and the other eligibility requirements are satisfied.

What Is a QDRO, and When Is a QILDRO Used?
A Qualified Domestic Relations Order (QDRO) is a court order that allows retirement benefits to be divided between spouses during divorce. Under 26 U.S.C. 414(p), ERISA-covered retirement plans, including most 401(k)s and private employer pensions, require a qualifying order before the plan administrator can distribute benefits to a former spouse. Illinois state and municipal pensions follow a different process using a Qualified Illinois Domestic Relations Order (QILDRO).
How a QDRO Works Under ERISA
The QDRO process involves several steps to ensure the retirement plan administrator can carry out the division specified in the divorce agreement.
- Establish the Division: The divorce decree or marital settlement agreement identifies how the retirement benefits will be divided.
- Prepare the Order: An attorney drafts the QDRO according to the retirement plan’s requirements. A divorce decree itself can qualify as a QDRO if it meets the applicable legal requirements.
- Request Preliminary Review: If the plan offers pre-approval, the proposed order is submitted to the plan administrator for review before court entry.
- Obtain Court Approval: The court enters the order, which is then submitted to the plan administrator for a formal qualification review.
- Address Required Revisions: If the administrator identifies deficiencies, the parties revise and resubmit the order.
- Divide the Benefits: Once the order is qualified, the administrator allocates the benefits through a separate account or scheduled payments, depending on the plan.
QILDROs for Illinois State and Municipal Pensions
Illinois public pensions, including the Illinois Municipal Retirement Fund (IMRF), the Teachers’ Retirement System (TRS), and Chicago’s Municipal Employees’ Annuity and Benefit Fund (MEABF), follow the QILDRO requirements under 40 ILCS 5/1-119. Unlike ERISA-covered plans, these pension systems operate under the Illinois Pension Code and require orders that comply with their specific rules.
For members who began participating in a covered retirement system before July 1, 1999, written consent is required for a QILDRO to take effect. Certain pension systems also require a separate QILDRO Calculation Court Order when benefits are divided by percentage. For example, TRS uses a Calculation Order to determine the amount payable to the former spouse under a percentage-based QILDRO.
What Happens If the Order Is Never Entered?
Without the required QDRO or QILDRO, a retirement plan cannot implement the division of benefits awarded to the former spouse. This can delay payment and create complications if the account holder retires, withdraws funds, or dies before the order is accepted.
Obtaining the order after divorce is still possible in certain circumstances, but the available options depend on the retirement plan and the terms of the divorce judgment. Completing the necessary order promptly helps prevent delays and protects the benefits awarded in the property division.
Key Takeaway: ERISA-covered retirement plans require a qualifying QDRO to divide benefits between spouses, while Illinois state and municipal pensions use a QILDRO. Each order must meet the applicable plan requirements, and completing it promptly helps prevent payment delays and complications after divorce.
How Is a Retirement Account Valued in a Divorce?
Retirement accounts and pensions are valued differently during an Illinois divorce because their benefits and payment structures vary. The valuation process considers the account balance or pension benefits, the applicable valuation date, and the portion classified as marital property.
Valuation Date
The value of retirement assets can change throughout a divorce, making the valuation date important when determining each spouse’s share. Under 750 ILCS 5/503(f), Illinois courts use the trial date to value marital property unless the parties agree to another date or the court selects a different date within its discretion. Section 503 also establishes the fair market value standard for property valuation.
For defined contribution plans, such as 401(k)s and IRAs, the account balance on the selected valuation date determines its value. For example, a retirement account worth $500,000 when the divorce was filed would be valued at $460,000 if it declined by 8% before trial.
Valuing Defined Benefit Pensions
Unlike retirement accounts with an established balance, defined benefit pensions provide future payments that must be valued based on the plan’s terms. Factors such as retirement age, years of service, early retirement options, cost of living adjustments, and survivor benefits influence the pension’s value.
When benefits are divided through deferred distribution, the marital portion can be determined using the years of service during marriage compared with the total years of credited service. For example, if 12 of 24 years were earned during marriage, 50% of the pension would represent the marital portion. If divided equally, the other spouse would receive 25% of the applicable pension benefit, subject to the plan’s rules and the court’s division order.
What Are the Tax Consequences of Dividing Retirement Assets?
Dividing retirement assets during divorce involves tax rules that affect how much each spouse ultimately receives. The tax consequences depend on the type of retirement account, how the funds are transferred, and whether the receiving spouse withdraws the money.
Direct Rollovers and Cash Distributions
Retirement benefits transferred to a spouse or former spouse under a qualifying QDRO can avoid immediate taxation when rolled directly into an eligible retirement account. If the receiving spouse takes a cash distribution instead, the amount is typically subject to income tax, although distributions made under a QDRO are exempt from the 10% additional tax on early withdrawals.
IRAs follow different rules because they do not require a QDRO. A properly executed transfer incident to divorce under Internal Revenue Code Section 408(d)(6) does not create an immediate tax liability. However, withdrawing funds from a traditional IRA to pay a former spouse directly can trigger income tax and an additional 10% early distribution tax if the account holder is under age 59½ and no exception applies.
Roth IRAs have separate tax rules based on the account’s holding period and whether the distribution meets the requirements for tax-free treatment. The QDRO exception to the 10% early distribution tax does not apply to IRA withdrawals, including Roth IRAs.
Pre-Tax Versus After-Tax Value
Retirement accounts and other marital assets can have different values after taxes, even when their stated balances are identical. For example, a $200,000 pre-tax 401(k) would leave approximately $140,000 if the entire balance were eventually taxed at a combined 30% rate. By comparison, $200,000 in home equity has different tax considerations, making it important to evaluate the after-tax value of assets during settlement negotiations.
Key Takeaway: Properly structured retirement transfers during divorce can avoid immediate taxation, while cash withdrawals can create income tax liabilities and early withdrawal penalties. Comparing assets based on their after-tax value helps spouses assess the financial impact of a proposed property division.
What If a Spouse Withdrew or Spent Retirement Funds?
Withdrawing or spending retirement funds during a divorce can affect how marital property is divided, particularly when the money was used for purposes unrelated to the marriage. Illinois courts examine these transactions to determine whether they constitute dissipation and whether an adjustment to the property division is warranted.
The Statutory Definition of Dissipation
Under 750 ILCS 5/503(d)(2), dissipation involves using marital assets for one spouse’s sole benefit, for purposes unrelated to the marriage, while the marriage is undergoing an irretrievable breakdown. If a spouse uses retirement savings for personal expenses during this period, the court can consider the amount spent when dividing marital property.
However, withdrawing retirement funds does not automatically constitute dissipation. The court considers how the money was used, including whether it covered legitimate household or marital expenses.
Notice and Look-Back Requirements
A spouse alleging dissipation must provide notice no later than 60 days before trial or 30 days after discovery closes, whichever is later. The notice must identify when the marriage began breaking down, the property involved, and the dates of the alleged dissipation. It must also be served on the other spouse, with a certificate of service filed with the court.
Illinois law also limits the period covered by a dissipation claim. Under Section 503(d)(2)(iv), claims are subject to a three-year limit tied to when the spouse knew or should have known about the spending, with an absolute cutoff of five years before the divorce petition was filed.
What Happens to Survivor Benefits If the Pension Holder Dies?
Survivor benefits determine whether a former spouse continues receiving pension payments after the account holder dies. The outcome depends on the pension plan, the benefit option selected, and the terms of the divorce order. Because certain benefit elections become difficult or impossible to change after retirement, addressing survivor rights during the divorce is important.
Survivor Annuities and Former Spouse Rights
Private pensions can provide survivor benefits through a qualified joint and survivor annuity or qualified preretirement survivor annuity under 29 U.S.C. 1055. Although divorce can end a former spouse’s surviving spouse status, a QDRO under 26 U.S.C. 414(p)(5) can preserve those rights. The order should specify whether survivor coverage is awarded and how its cost will be handled.
Illinois public pensions follow different rules. For example, the Teachers’ Retirement System does not permit monthly survivor benefits to be divided through a QILDRO, although eligible lump sum death benefits can be allocated to an alternate payee. These distinctions make it important to review the pension system’s requirements before finalizing the divorce agreement.
Beneficiary Designations During and After the Divorce
Survivor benefits also depend on beneficiary designations, which must comply with the retirement plan’s rules, applicable federal law, and any qualifying domestic relations order. Following a divorce, spouses should review their 401(k), IRA, and pension beneficiary designations to ensure they reflect the intended recipients. Certain plans require spousal consent for beneficiary changes, so updating a designation alone does not always override existing survivor rights.

Frequently Asked Questions About Retirement Accounts in an Illinois Divorce
Is a Spouse Entitled to Retirement Benefits If They Did Not Work?
Yes. Retirement benefits earned during marriage are presumed marital property under 750 ILCS 5/503(b)(2), even if only one spouse worked. Illinois courts also consider homemaking and other non-financial contributions when dividing marital assets.
Can a Pension Be Divided If the Spouse Is Already Retired?
Yes. A pension already paying benefits can be divided through an appropriate court order, such as a QDRO or QILDRO. The plan’s rules and existing survivor benefit elections determine the available division options.
How Long Does It Take to Complete a QDRO or QILDRO?
Completing a QDRO or QILDRO can take weeks or months, depending on court processing, plan administrator requirements, and whether revisions are needed. There is no single statewide completion deadline.
Who Pays for Drafting the Order?
Spouses can agree to split the drafting costs or assign them to one party. If they cannot agree, the court can allocate the expense. Some retirement plans also charge processing fees.
Can a Spouse Withdraw From a Retirement Account While the Divorce Is Pending?
Yes, depending on the plan’s rules and any court restrictions. However, withdrawals can affect property division and lead to dissipation claims if marital funds are spent for purposes unrelated to the marriage during its breakdown.
Can a Prenuptial or Postnuptial Agreement Change How Retirement Accounts Are Divided?
Yes. A valid prenuptial or postnuptial agreement can determine how retirement assets are classified and divided under 750 ILCS 5/503(a)(4). However, enforceability requirements and federal spousal consent rules for certain retirement plans can affect the agreement’s application.
