How Is a Military Pension Divided in an Illinois Gray Divorce?

 Posted on June 11, 2026 in Retirement

If you or your spouse served in the military, a pension may be one of the largest assets in your divorce. Many couples who split after 50 have built their retirement plans around that income. According to the U.S. Department of Veterans Affairs, nearly 392,000 of Illinois's roughly 621,000 veterans are age 50 or older, which means a large share of the people this law affects are in or near the gray divorce years. 

In 2026, Illinois courts have clear rules for dividing military pensions. Those rules work differently from the ones for a 401(k) or a civilian pension, and knowing the difference can protect your financial future. A Naperville, IL gray divorce attorney can help you account for every part of your military retirement in your property division.

How Does Illinois Law Treat a Military Pension as Marital Property in a Gray Divorce?

A court does not divide a military pension based on its own calculations; it must make that call under the law. The federal law that applies is the Uniformed Services Former Spouses' Protection Act, or USFSPA, which Congress passed in 1982. It allows state courts to treat military retired pay as marital property when they have proper jurisdiction over the service member. 

In Illinois, that means the pension is divided under 750 ILCS 5/503, the property division section of the Illinois Marriage and Dissolution of Marriage Act. In accordance with this statute, Illinois uses equitable distribution, dividing marital property fairly, but not always fifty-fifty. 

For a military pension, only the portion earned during the marriage is subject to the division. Service time accumulated before the marriage remains with the service member. Military disability pay from the Department of Veterans Affairs also cannot be divided as marital property. Only disposable retired pay, which is the pension minus certain deductions, is what the court can divide.

What the 10/10 Rule Means for Receiving Military Pension Payments After an Illinois Divorce

A court can award a spouse a share of a military pension, but that does not automatically mean the spouse will receive payments directly from the government. The 10/10 rule controls how payments are delivered. 

If the marriage lasted at least ten years and the service member served for at least ten of those same years, the Defense Finance and Accounting Service, known as DFAS, can pay the former spouse directly. The non-military spouse gets their share from the federal government, and they do not have to wait for the service member to send it. 

If the marriage falls short of that ten-year overlap, a court can still award a share of the pension. The non-military spouse would then collect it from the service member instead. In gray divorce cases, which often involve long marriages, the 10/10 threshold is commonly met. Still, the exact length of the overlap is worth confirming early on to plan for its implications.

How the 2017 Frozen Benefit Rule Changed Military Pension Division in Illinois Divorces

Before 2017, courts could base a former spouse's share on the rank and pay the service member reached at retirement. That was true even if the divorce happened years earlier. A rule change in 2017 ended that method. 

Under the frozen benefit rule, the share is now based on rank and years of service at the time of the divorce. Raises and extra service time after the divorce belong only to the service member. If the divorce order became final after December 23, 2016, and the service member was not yet receiving retired pay, this rule usually applies. If you divorced before 2017, the older rules may apply to your case, so it is worth reviewing your decree carefully.

Why a Military Pension Is Not Divided the Same Way as a Civilian Retirement Account

A 401(k) or private pension is divided under a Qualified Domestic Relations Order (QDRO). A military pension does not use a QDRO. Instead, the divorce court issues an order that goes directly to DFAS. That order must meet specific federal rules, and if it is missing required language, DFAS can reject it. If it is rejected, the former spouse does not receive their share until the order is corrected and resubmitted. This is one of the most common and costly mistakes in military divorce cases.
