You’ve been living apart for months—maybe longer. HR just dropped a year-end bonus, a big commission, or a new RSU grant. Your first thought: “I earned this after we split. Do I still have to share it?” Here’s the counterintuitive part: Illinois has no “date of separation” for dividing property. The paycheck hitting now can still be part of the marital estate.
If you’re searching “does separation date matter in Illinois divorce,” you’re trying to find a clean cutoff that lets you keep what you’re earning while the case drags on. Illinois doesn’t use that shortcut. The court looks to the date the divorce is finalized—not the date you moved out—to decide what you acquired during the marriage.
Short answer: unless you have a judgment of legal separation or a court order that says otherwise, assume compensation earned before the divorce judgment is marital. This article explains why, how legal separation can change it, how “dissipation” works if someone is spending down accounts post‑split, how valuation dates are chosen, and what to do right now to protect yourself and stay credible.
Quick answer: Does separation change what’s marital in Illinois?
No. Separation—moving out or living separate lives—does not end marital property rights in Illinois. Courts have said for decades that there is no “de facto” separation date that cuts off marital property. The presumption is that anything acquired during the marriage and before the divorce judgment is marital, regardless of when you stopped living together. See 750 ILCS 5/503(a) and 5/503(b)(1); In re Marriage of Brooks (1985) and In re Marriage of Steele (1991), which reject using a separation date as the cutoff.
Practically, that means a bonus paid while you’re apart, a commission that clears next quarter, or equity granted during the case can be subject to division unless a court order or legal separation judgment changes the analysis.
What counts as “marital property” when we’re living apart?
Illinois presumes that property acquired after the marriage and before the divorce judgment is marital. 750 ILCS 5/503(a). “Property” is broader than bank balances. It includes rights to payment—bonuses you’ve earned, commissions you’ve generated, equity awards granted for your service, and increases in retirement accounts funded during that period.
Some items are non‑marital by statute—like a gift or inheritance to you alone—but the default is marital. Title does not control; having your name on the check doesn’t make it “yours” for divorce purposes. The key is when and why the right was acquired, not where it’s deposited.
Are paychecks, bonuses, and RSUs earned after separation marital?
Usually yes, if they are earned before the divorce judgment. Payment timing is not the same as earning. If a commission paid in October was generated by sales you closed in August—while you were still legally married and before judgment—it will likely be treated as marital. Likewise for a performance bonus calculated on a prior measurement period.
Equity is similar but more nuanced. RSUs or options granted during the marriage are often marital to the extent they compensate past or present service before judgment. If an award is explicitly for future service after the divorce judgment, that future component may be treated as non‑marital. Expect the court to examine the plan documents, grant notices, vesting schedules, and what the employer says the award is meant to reward.
I earned it after we split but before divorce—does timing matter?
Yes—but not the way most people think. The relevant question is not “were we living together?” It’s “was the right to this money earned or acquired before the divorce judgment?” Under 750 ILCS 5/503(a), the presumption captures property acquired during the marriage, and appellate courts in Brooks and Steele make clear that separation alone does not move the goalposts.
Two practical consequences:
- If the compensation relates to a period fully before the divorce judgment, assume it is marital—even if the check clears while you’re sleeping on a friend’s couch.
- If compensation clearly rewards post‑judgment service, that portion can be non‑marital. Precise documentation is essential to show what period the payment covers.
If your situation involves layered comp—salary plus bonus, commissions with chargebacks, or equity with staggered vesting—classification and valuation can get technical quickly. That is where targeted strategy around asset division matters.

Does a judgment of legal separation change the answer?
It can change it entirely. Illinois law expressly provides that property acquired after a judgment of legal separation is non‑marital. 750 ILCS 5/503(b)(1). That is different from simply living apart. A judgment of legal separation is a court order. If you have one, assets and income acquired after that judgment are generally outside the marital estate.
Two cautions:
- The protection starts on the date of the legal separation judgment, not the day you moved out.
- A legal separation judgment often leaves support and parenting issues to be decided separately; get advice on whether it makes strategic sense before you pursue it.
How do courts treat post‑separation spending and “dissipation”?
Living apart does not end the marriage, but it does start a period where spending can trigger scrutiny. “Dissipation” is the term courts use when a spouse uses marital funds for a sole, non‑marital purpose during the breakdown of the marriage. Classic examples include secret cash withdrawals, gifts to a new partner, or selling marital assets at a steep discount to cover personal expenses.
If the court finds dissipation, it can compensate the other spouse by assigning more of the remaining marital property to them. The remedy is financial, not moral. Practically, this means:
- Keep normal, documented household spending going.
- Avoid large, unexplained transfers.
- If you must make a big expenditure, preserve the receipts and the rationale.
Remember: classification (marital vs. non‑marital) is one issue; whether someone wasted marital value is another. The court can find a bonus marital and still address any wasteful spending out of it through the division.
Can we set our own cutoff date or get a temporary order?
You can’t change state law by private agreement, but you can create clarity and reduce fights. Two tools help:
- Agreed temporary orders. Parties often agree—and judges frequently approve reasonable orders—that income earned after a specific date will be held in a separate account, that certain awards will not be liquidated, or that neither party will move or spend defined assets without consent or court approval. While an agreed order doesn’t re‑write the statute, it can preserve assets and set practical expectations the court is likely to honor at the end.
- Settlement terms in writing. If both spouses agree that, for example, each will keep post‑filing W‑2 income or that each keeps RSUs granted after a certain date, that allocation can be incorporated into the final judgment.
If agreement isn’t possible, the court can enter temporary orders to maintain the financial status quo and prevent asset transfers while your asset‑division issues are sorted out.
How do valuation-date choices affect all of this?
Classification answers “what is marital.” Valuation answers “what is it worth.” Illinois gives the court discretion to choose a valuation date—often close to trial. 750 ILCS 5/503(f). That choice matters when values are moving:
- A business that rebounds during the case might be valued later to capture the recovery for the marital estate.
- A retirement account that swings with the market could be valued on a date the court finds equitable.
Valuation does not change whether an asset is marital. It changes the number attached to the marital portion.
What records and pay docs should I save right now?
Cook County requires each party to serve a Financial Affidavit in pre‑judgment cases seeking property division. That means post‑separation income and awards must be disclosed early. Expect to produce documentation, and understand that better records often mean better outcomes.
Save:
- Pay stubs, year‑to‑date summaries, W‑2s/1099s, and payroll portal downloads.
- Bonus and commission plans, attainment reports, payout calculations, and emails confirming targets or true‑ups.
- Equity grant notices, plan documents, vesting schedules, performance metrics, and brokerage statements.
- Bank and brokerage statements (all accounts receiving pay or awards), including transaction histories and check images.
- Offer letters, promotion letters, and any HR communications describing what a payment is meant to reward.
- Tax returns and employer year‑end compensation summaries.
If you expect a dissipation dispute, keep receipts for large expenditures and a short note describing the purpose. To understand what your spouse must disclose and how to get it, see our guide to discovery in Illinois divorce.
What should you take away?
- In Illinois, the marriage doesn’t end for property purposes until the court enters a divorce judgment. Separation by itself does not cut off marital property rights. Brooks and Steele confirm this, and 750 ILCS 5/503(a) and (b)(1) supply the governing presumption.
- Assume new compensation earned before judgment—paychecks, bonuses, commissions, equity—will be treated as marital unless a judgment of legal separation or a court order says otherwise.
- Classification turns on why and when the right to payment was earned; valuation is a separate step, and the court can choose the valuation date under 750 ILCS 5/503(f).
- Documentation and early, credible disclosure (including your Financial Affidavit in Cook County) protect you more than arguments do.
