In Illinois, non-marital property generally stays with its owner; marital property is divided equitably. An account in one name is not automatically separate property. The source of the asset, later transfers and the evidence connecting them matter.

The approach
Illinois uses equitable distribution rather than an automatic 50/50 rule. The central questions are what is marital, what is non-marital, what each asset is worth, and how the overall division works after debt and taxes are considered.
Marital vs. non-marital
Premarital property, inheritance, gifts and excluded property may remain non-marital, but commingling and tracing can materially change the analysis.

Valuation
Real estate, businesses, pensions and investment interests may need formal valuation. A number without methodology is not useful evidence.
Dissipation + concealment
Unusual transfers, unexplained spending and incomplete disclosure require a disciplined record and timely procedural action.
What will you keep in an Illinois divorce?
Illinois courts assign each spouse's non-marital property to that spouse and divide marital property equitably. The difficult part is often proving which category an asset belongs in. A premarital home, inherited account or business interest can require years of records to explain what was acquired, what changed and where the money went.
Under 750 ILCS 5/503(a), (b), (c) and (d), property acquired during the marriage is generally presumed marital even if only one spouse's name appears on the account or deed. Overcoming that presumption requires clear and convincing evidence of a statutory exception. Ownership, tracing and reimbursement are related questions, but they are not interchangeable.
A home owned before marriage
A home acquired before marriage generally begins as non-marital property. Later changes in title, refinancing, mortgage payments and improvements require separate examination. Paying expenses with marital funds does not automatically give the other spouse half the house. It can raise a reimbursement question. Transferring the home into joint ownership raises a marital-property presumption; the purpose and evidence of the transfer matter.
Keep the purchase closing statement, original and later deeds, loan records, mortgage-payment history and records of major improvements. A current mortgage statement alone may not establish the source of the original equity or later contributions.
Inheritances, gifts and trusts
For joint-account deposits, inherited down payments and a concrete tracing example, read is inheritance divided in an Illinois divorce?
An inheritance or gift to one spouse is generally non-marital, including property acquired in exchange for it. The paper trail matters when inherited funds move through several accounts, pay down debt or help purchase a home. Preserve estate-distribution records, gift documentation and the statements showing receipt and subsequent transfers.
A trust requires examination of the trust instrument and amendments, the source of its funding, the beneficiary's rights and the distributions actually received. Calling an asset a “family trust” does not answer every divorce question. Distinguish ownership or a beneficial interest from distributions and from the separate income questions that may arise in support proceedings.
Tracing, commingling and transmutation
Tracing connects an asset today to its claimed non-marital source. Commingling means marital and non-marital property have been mixed. Under section 503(c), the effect depends on whether the contributed property retains its identity and whether the funds went into an existing estate or newly acquired property. Loss of identity can change classification; mixing funds is not, by itself, a complete legal analysis.
For an investment account, that work may mean reconciling the premarital balance, deposits from earnings, inherited deposits, purchases, sales, withdrawals and transfers into replacement accounts. A balance from the wedding month and a balance today may leave the important transactions unexplained. Preserve complete statements and transaction histories before older records become harder to obtain.
Appreciation and reimbursement claims
The increase in value of non-marital property remains non-marital under section 503(a)(7), subject to reimbursement rights. A contribution from one estate to another may support reimbursement even if the contributed property has changed classification. Section 503(c)(2)(A) excludes reimbursement for a gift or a contribution that cannot be traced by clear and convincing evidence.
A spouse's work on non-marital property presents a distinct issue: significant personal effort that produces substantial appreciation can support reimbursement to the marital estate, unless that estate was reasonably compensated for the effort. For a business, the analysis may require separating market growth, invested capital, the owner's work and compensation already paid. These issues connect directly to business-owner divorce and the broader high-asset divorce analysis.
Three tracing problems worth separating
These hypothetical examples show how to organize the evidence. They are not predictions of a result or descriptions of client matters.
Inherited money used for a down payment
Suppose an inheritance arrives in one spouse’s account, moves through a joint checking account and is used at a home closing. A statement showing the inheritance alone leaves two transfers unexplained. Build the sequence: estate distribution, receiving-account statement, transfer confirmation, joint-account statement, closing wire and deed. Identify any other money added along the way.
The questions include tracing, the effect of title and whether a gift was intended. Establishing where the money came from is a different task from establishing how the resulting home should be classified or whether reimbursement is available.
A premarital investment account with later deposits
Suppose an account existed before marriage, then received payroll deposits and transferred to a new brokerage. Start with the holdings at marriage. Follow deposits, withdrawals, purchases, sales and the transfer between custodians. Keep statements from both firms so the last balance at one can be connected to the first balance at the next.
Separate new contributions from changes in investment value. A current screenshot may show what exists today, but it cannot explain the account’s history. Missing statements should be identified early so counsel can evaluate how to obtain or reconstruct the record.
A business owned before marriage that grew
Suppose an owner entered the marriage with an ownership interest and continued working in the business. Organize acquisition documents, ownership changes, capital contributions, compensation, distributions and financial statements. Ask which records explain the owner’s work and which explain changes in business value.
Classification, valuation and compensation are separate assignments. The business-owner guide explains how to frame the valuation and liquidity questions; the reimbursement discussion explains why the work performed during marriage also matters.
Build the record before arguing about the result
- Identify when and how each disputed asset was acquired.
- Collect statements around the marriage, inheritance, purchase and significant transfers.
- Keep deeds, closing documents, trust instruments, business ownership records and any premarital or postnuptial agreement.
- Separate the claimed non-marital asset from any claim for reimbursement.
- Identify missing records and disclose claimed non-marital interests on time.

Missing money, disputed spending and dissipation
A missing asset and a dissipation claim are not the same question. An account that was not disclosed may still exist and need to be identified, classified and valued. Money that was spent raises different questions: where it went, what it paid for, when it was spent and whether a legal claim is supported.
Illinois decisions describe dissipation in terms of marital property used for one spouse’s sole benefit, for a purpose unrelated to the marriage, while the marriage is undergoing an irreconcilable breakdown. The circumstances and timing matter. A transaction that one spouse dislikes is not, by that fact alone, proof of dissipation. Courts also examine conduct detrimental to the marital estate even when a spouse does not necessarily receive a personal benefit. See In re Marriage of Schneeweis, 2016 IL App (2d) 140147, ¶¶33–37, discussing the Illinois Supreme Court’s definition in O’Neill.
Build a transaction record, not just an accusation.
Start with the records you can lawfully access. For each disputed transaction, note the date, amount, source account, recipient or destination, stated purpose and supporting document. Distinguish a known fact from an inference. A transfer to another account is a lead to follow, not necessarily an expense or a loss.
- Source: bank, brokerage, credit-card or business records identifying where the money began.
- Destination: transfer confirmations, canceled checks, recipient information and statements from the receiving account when available.
- Explanation: invoices, receipts, loan documents or communications addressing what the transaction was for.
- Timing: the transaction date, relevant relationship timeline, and when you first learned of the issue.
- Gaps: missing months, unknown institutions, unexplained cash withdrawals or differences between account records and disclosure.
For example, a hypothetical $20,000 transfer from joint checking to a business account should be traced through both accounts. It might relate to an asset, a documented business expense, a loan or another use. The next task is to identify the records that distinguish those possibilities. The number alone does not establish a legal result.
Dissipation notice has specific requirements.
Under 750 ILCS 5/503(d)(2), notice of intent to claim dissipation is due no later than 60 days before trial or 30 days after discovery closes, whichever is later. The notice must identify at least the date or period when the marriage began undergoing an irretrievable breakdown, the property claimed to have been dissipated, and the date or period of the alleged dissipation. The section also addresses filing and service.
The statute contains additional three-year knowledge and five-year pre-petition limitations. Those require application to the actual chronology. Tell counsel about the suspected transactions and discovery dates promptly rather than treating the trial deadline as the only timing issue.
Preservation and urgent financial concerns
Keep complete statements and original files, including the surrounding transactions. Avoid altering records or accessing an account without authority. Identify unavailable records so counsel can evaluate the appropriate disclosure or discovery process. Do not move or hide assets in response to a suspicion.
Section 501 provides a framework for requests for temporary relief, including certain restraints on property transfers, supported by the required facts. An urgent concern should be evaluated on its evidence and procedural requirements; filing for divorce alone should not be treated as a guarantee that every account is frozen.

Questions that come up early.
Does Illinois divide everything 50/50?
No. Illinois divides marital property in just proportions after considering statutory factors, including contributions, economic circumstances, the length of the marriage, needs and tax consequences. Each spouse’s established non-marital property is assigned to that spouse, subject to issues such as reimbursement. An equal marital division is possible, but neither an automatic half-share of everything nor an automatic penalty for marital misconduct is the rule.
Source: 750 ILCS 5/503(d).
Is an inheritance divided in divorce?
An inheritance received by one spouse generally starts as non-marital property. Its later treatment matters: joint ownership, gifts, spending and mixing funds can affect the claim. Keep estate-distribution records and the statements connecting the inheritance to what exists now. Tracing the source and proving that a transfer was not a gift are different tasks; showing an inheritance once existed does not alone decide ownership of a later joint asset.
Source: 750 ILCS 5/503(a)(1), (b)(1) and (c).
What happens to a business?
Illinois first classifies the ownership interest, then values and divides the marital estate under the statutory factors. A non-owner spouse may receive a financial allocation without becoming a co-owner. Settlement structures may use other assets or payments, but feasibility, taxes and available cash matter. Premarital ownership, later contributions, compensation and any reimbursement claim require separate analysis.
Is property in my name alone non-marital in Illinois?
Not necessarily. Property acquired during marriage is generally presumed marital regardless of whose name appears on the title. A claimed statutory exception must be established by clear and convincing evidence.
Does putting inherited money in a joint account automatically end my claim?
Not necessarily. Traceability, loss of identity, the destination of the money and evidence of a gift matter. Keep the complete transfer history rather than relying only on the inheritance document.
Do I keep the increase in value of premarital property?
An increase in the value of non-marital property is generally non-marital under section 503(a)(7), subject to reimbursement rights. Classification of the growth and reimbursement for contributions are separate questions.
Does moving out make new earnings non-marital?
Living apart alone does not end the marital-property presumption. The timing rules and exceptions under section 503 must be applied; a judgment of legal separation differs from an informal separation.
What if I do not have all the old account statements?
Make a timeline of the institutions, account changes and missing periods. Preserve the records you can lawfully access and tell counsel about gaps early. Do not assume a current balance proves the source of the money.
