A military divorce in Illinois runs on two sets of rules at once. Illinois decides whether you can file here, how property gets divided, how support is calculated, and how parenting time is allocated. Federal law decides what happens to the pension, who keeps health coverage, whether the case can be paused while someone is deployed, and what a court is allowed to consider when a parent receives orders. Those two systems do not always point the same direction, and the gaps between them are where military families lose things they did not know were at stake.
This article speaks to both sides. The service member and the civilian spouse are usually searching for the same answers with opposite interests, and there is no version of this topic that is honest to one side and useful to the other. Where the two positions diverge, both are stated.
Key Points
- Being stationed in Illinois for 90 days satisfies the residency requirement, even if your legal domicile is another state
- A deployed service member can request a stay, but it is a minimum of 90 days and it is not automatic
- An Illinois court can divide military retired pay regardless of how long the marriage lasted Survivor Benefit Plan coverage must be filed with the Defense Finance and Accounting Service within one year of the divorce or it is lost permanently
- Deployment alone cannot be the sole reason a court permanently changes a parenting arrangement
Where You File, and Why the Choice Is Often Yours
Illinois requires that one spouse have been a resident of the state for 90 days. Under 750 ILCS 5/401(a), being stationed in Illinois while serving in the armed forces counts the same as living here. A service member assigned to an Illinois installation qualifies after 90 days even though their legal domicile remains Texas or Florida or wherever they enlisted.
Only one spouse has to meet the requirement. A civilian spouse who stays in Illinois can file here while the service member is stationed in another state or deployed overseas. That single fact opens the door to a filing decision most civilian couples never face.
Military families frequently qualify to file in two or three states at the same time: the state of the member’s legal domicile, the state where they are stationed, and the state where the civilian spouse lives. Those states do not treat maintenance the same way, do not calculate support the same way, and do not divide property the same way. The choice of forum can be worth more than anything argued later in the case.
Statewide residency and venue are separate questions. Where in Illinois the case is heard is governed by 750 ILCS 5/104, which puts the case in the county where either party resides. There is no separate county waiting period to satisfy.

What the Servicemembers Civil Relief Act Protects, and What It Does Not
A note on the name, because it matters for how current your information is. The Soldiers’ and Sailors’ Civil Relief Act of 1940 was repealed and replaced by the Servicemembers Civil Relief Act in 2003. Several Illinois law firm websites still describe protections under the older statute, including firms in DuPage County. If the source you are reading uses the old name, treat everything else on the page with the same caution.
The current statute is found at 50 U.S.C. § 3901 and following. Two provisions matter in family court.
Protection Against Default Judgments
Section 3931 applies when a service member has not appeared in the case. Before a court can enter a default judgment, the party seeking it must file an affidavit stating whether the other party is in military service. If the affidavit shows military service, or cannot rule it out, the court appoints an attorney to represent the absent member. That attorney’s job is to locate the member and, in most cases, request a stay.
If a default judgment is entered anyway while a member is serving, the statute provides a route to reopen it. The application must come while the member is still serving or within 90 days after service ends, and the member must show that military service prejudiced the ability to defend and that a meritorious defense exists.
The 90-Day Stay
Section 3932 applies when the service member has received actual notice of the case. On a proper application, the court must grant a stay of at least 90 days. Additional stays are available, but they are discretionary, and if the court denies one it must appoint counsel for the member.
The stay does not run for the length of the deployment plus 60 days. That description circulates widely and is not what the statute provides. The 90-day minimum is the floor, and anything beyond it depends on the judge.
A Stay Is Not Automatic
The application must be in writing, must explain how military duties materially affect your ability to appear, must state when you will be able to appear, and must include a letter from your commanding officer confirming that leave is not authorized. Deployment alone, with no filing, does not pause anything. Cases have proceeded to judgment against service members who assumed otherwise.
Military Retirement Is Divisible No Matter How Long You Were Married
This is the most common and most costly misunderstanding in military divorce, and correcting it changes what people do next.
What the 10/10 Rule Actually Controls
The Uniformed Services Former Spouses’ Protection Act, at 10 U.S.C. § 1408, allows state courts to treat disposable military retired pay as marital property. Illinois courts do exactly that, applying the same equitable distribution principles used for any other pension.
The ten-year rule controls one thing and one thing only: whether the Defense Finance and Accounting Service will pay the former spouse’s share directly. If the marriage overlapped at least ten years of creditable service, the former spouse submits a certified copy of the order and receives payments straight from the pay center. If the overlap is shorter, the court can still award a share of the pension. The service member simply has to pay it.
The practical difference is collection, not entitlement. Direct payment is automatic and reliable. Payment from a former spouse depends on compliance and, when compliance fails, on going back to court. That is a meaningful difference, and it is worth drafting around. It is not a reason to walk away from a claim.
The Frozen Benefit Rule
For judgments entered after December 23, 2016, the National Defense Authorization Act changed how the divisible amount is calculated. The share is now fixed to the member’s pay grade and years of creditable service as of the date of the divorce, rather than at retirement.
For the service member, this means promotions, longevity increases, and pay table adjustments earned after the judgment stay with them. For the former spouse, it means the share stops growing with a career that continues for another decade.
It also makes timing consequential. If a settlement is reached in one month and the judgment is entered several months later, after a promotion, an order drafted to the wrong figures can be rejected by the pay center. Orders in these cases have to state rank, years of service, and where applicable the high-three average, as of the correct date.
Disposable Pay and the Disability Waiver
Only disposable retired pay can be divided. Certain amounts come off the top before any division happens, including retired pay waived in order to receive VA disability compensation.
The Supreme Court held in Mansell v. Mansell, 490 U.S. 581 (1989), that waived retired pay is beyond the reach of state courts. In Howell v. Howell, 581 U.S. 214 (2017), the Court went further and held that a state court cannot order a veteran to reimburse a former spouse when a post-divorce waiver reduces the share already awarded. Indemnification language drafted before Howell is unenforceable, and settlements that assume a fixed dollar amount of pension income can be undone years later by a disability rating.
If You Are the Service Member
Confirm that the order uses the correct frozen figures and does not attempt to divide disability compensation. Watch for indemnification language that Howell no longer permits, and understand that agreeing to a fixed monthly dollar figure instead of a percentage transfers all of the future risk to you.
If You Are the Civilian Spouse
Confirm the order is drafted to pay center requirements rather than only to Illinois standards, because an order that satisfies a judge can still be rejected in Cleveland. Ask for the Leave and Earnings Statement and the full service record, and address in the judgment what happens if a future disability waiver reduces your share.
The Survivor Benefit Plan Deadline That Cannot Be Undone
Military retired pay stops when the retiree dies. The Survivor Benefit Plan is what continues an income stream to a designated beneficiary afterward, and for a former spouse who was awarded a share of the pension, it is the only thing standing between them and losing that income entirely.
An Illinois judgment can order a service member to elect former spouse coverage. The judgment by itself does not create the coverage. Someone has to notify the Defense Finance and Accounting Service, and the window is one year from the date of the divorce.
The service member can make the election. If they do not, the former spouse can file a deemed election using DD Form 2656-10 with a certified copy of the judgment. If neither happens within the year, the coverage is gone. A court can hold the member in contempt, but contempt does not restore an expired election.
Health Care and Base Access After the Judgment
Whether a former spouse keeps TRICARE depends on three numbers: length of marriage, length of creditable service, and how much of the two overlapped.
1
20/20/20
Twenty years of marriage, twenty years of creditable service, and twenty years of overlap. The former spouse keeps TRICARE, commissary, and exchange privileges in their own right for as long as they remain unmarried.
2
20/20/15
Twenty years of marriage, twenty years of service, and at least fifteen years of overlap but less than twenty. The former spouse receives one year of transitional TRICARE coverage and does not keep base shopping privileges.
3
Below Both Thresholds
Coverage ends the day the judgment is entered. The Continued Health Care Benefit Program is available as a paid bridge for up to 36 months, priced comparably to individual market coverage.
Note that these are hard thresholds. Fifteen years of overlap is fifteen years, and a case sitting near a line is worth checking against the official service record rather than a recollection of dates. In a marriage approaching nineteen years, the difference between finalizing this spring and finalizing next year can be a lifetime of health coverage.
Remarriage ends eligibility permanently. If a former spouse who qualified under 20/20/20 remarries and that second marriage ends, TRICARE eligibility does not come back.

Decision-Making and Parenting Time When a Parent Deploys
Illinois eliminated the terms custody and visitation in 2016. What replaced them matters here, because the older vocabulary encourages a winner-and-loser framing that fits military families badly. Significant decision-making responsibilities are allocated under 750 ILCS 5/602.5, covering education, health, religion, and extracurricular activities. Parenting time is allocated separately under 750 ILCS 5/602.7. A parent can hold substantial decision-making authority while a deployment schedule limits day-to-day parenting time, and neither one determines the other.
Substitute Parenting Time During Deployment
Illinois law provides something most states do not. Under 750 ILCS 5/602.7(d), a parent who is deployed or who has orders to deploy can ask the court to designate a person known to the child to exercise their parenting time while they are gone. In practice that is often a grandparent, a stepparent, or an adult sibling who already has a relationship with the child.
The court applies the same best interest factors to the designated substitute that it applies to any parenting arrangement. This is not automatic and it is not a right. It requires a motion, which means it needs to be raised before departure rather than from overseas.
Deployment Cannot Be the Sole Reason to Change an Order
Federal law backstops this. Under 50 U.S.C. § 3938, a court considering a permanent change to a service member’s parenting arrangement may not treat the member’s absence due to deployment, or the possibility of future deployment, as the sole factor in deciding the child’s best interest.
The better approach is to write the parenting plan to anticipate deployment rather than react to it. A plan that already specifies what happens during a deployment, how virtual contact will work, who exercises substitute parenting time, and how the schedule resumes on return is far more durable than one modified under time pressure with orders already in hand.
Support Calculated on Military Pay
Allowances Count as Income
Illinois calculates child support using the income shares model under 750 ILCS 5/505, which combines both parents’ net incomes and allocates a support obligation proportionally.
Base pay is only part of a service member’s compensation. The Basic Allowance for Housing and the Basic Allowance for Subsistence are not taxable, which leads people to assume they are not income for support purposes. Illinois courts have held otherwise for three decades. In re Marriage of McGowan, 265 Ill. App. 3d 976 (1st Dist. 1994), directed that military allowances be included in income, and In re Marriage of Baylor, 324 Ill. App. 3d 213 (2001), followed it. The statute reinforces the result: 750 ILCS 5/505(a)(3)(B) counts a housing allowance as income where the amount is significant and reduces personal expenses.
The practical consequence is that the Leave and Earnings Statement matters more than the W-2. A W-2 reflecting only taxable pay can understate actual income by a wide margin, particularly for a member drawing housing allowance in a high-cost area.
About the 60 Percent Figure
You may encounter a claim that support cannot exceed 60 percent of a service member’s pay and allowances. That number is a misreading of federal garnishment limits, which cap what can be involuntarily withheld from a member’s pay under a support order. The ceiling shifts depending on whether the member supports another spouse or child and whether past-due support is being collected. It restricts collection. It is not a limit on what an Illinois judge can order.
Separately, each service branch imposes its own interim support obligations on members before any court order exists. Those regulations differ by branch and are enforced through the chain of command rather than through the court, and a member who ignores them can face consequences at work regardless of what is happening in the case.
Maintenance
Maintenance follows the statutory guideline calculation under 750 ILCS 5/504 when the parties’ combined gross income falls within the guideline range. One point specific to military cases: retired pay that has already been divided as marital property should not be counted again as the member’s income for maintenance purposes. Doing so awards the same dollars twice.
Rough figures for both calculations are available through the child support calculator and the alimony calculator, though the allowance question above is exactly the kind of input a calculator cannot resolve on its own. The factors that shape a maintenance award apply the same way in military cases.
Where Illinois Military Divorce Cases Are Filed
Illinois has a substantial military presence spread across the state. Naval Station Great Lakes sits in Lake County. Rock Island Arsenal anchors the Quad Cities. Scott Air Force Base draws families to the O’Fallon and Belleville area, and the 182nd Airlift Wing operates out of Peoria.
Less obvious, and more common in the Chicago area, are Guard and Reserve members living throughout the collar counties. A drilling reservist called to active duty for more than 30 consecutive days receives the same Servicemembers Civil Relief Act protections as an active duty member, and many do not realize it until a default is already looming.
DuPage County cases are generally heard at the 18th Judicial Circuit courthouse in Wheaton. Cases from the surrounding counties follow their own circuit courts.
Frequently Asked Questions
Yes, if you have been stationed in Illinois for 90 days. Under 750 ILCS 5/401(a), military presence in the state counts the same as residence. Your domicile elsewhere does not prevent an Illinois filing, though it can raise questions about which state should hear the case if your spouse files somewhere else first.
They can file. Whether the case proceeds is a different question. Under 50 U.S.C. § 3932 you can apply for a stay of at least 90 days, and under 50 U.S.C. § 3931 the court cannot enter a default judgment against you without first reviewing an affidavit of military service and appointing counsel if you are serving. None of this happens on its own. Someone has to file the application.
No. The ten-year overlap determines whether the Defense Finance and Accounting Service pays your share directly. An Illinois court can award you a portion of the marital share of the pension regardless of how long the marriage lasted. Below the threshold, your former spouse pays you rather than the pay center.
No. Disability compensation is not divisible, and retired pay waived to receive it comes out of the divisible amount before division. Mansell v. Mansell established this, and Howell v. Howell later held that a court cannot order a veteran to compensate a former spouse for a reduction caused by a post-divorce waiver.
It depends on the overlap between the marriage and the service. Meeting the 20/20/20 thresholds preserves coverage indefinitely while you remain unmarried. Meeting 20/20/15 provides one transitional year. Below both, coverage ends with the judgment, and the Continued Health Care Benefit Program is available for up to 36 months as a paid substitute.
Yes. Illinois courts include military allowances in income for support purposes even though those allowances are not taxable. This has been settled Illinois law since McGowan in 1994.
Raise it with the court before you leave. Under 750 ILCS 5/602.7(d) you can ask to designate someone the child already knows to exercise your parenting time during the deployment. Federal law separately prevents a court from making deployment the sole basis for a permanent change to your arrangement.
Yes. Unless the former spouse independently qualifies under the 20/20/20 rule, dependent identification and base privileges end when the judgment is entered. The identification card is required to be turned in.
