Illinois courts divide marital debt equitably, not equally, under 750 ILCS 5/503. The court considers 12 statutory factors including each spouse's income, the duration of marriage, and contributions to the marital estate when determining who pays what debts. Credit card debt incurred during marriage is presumed marital regardless of whose name is on the account, while pre-marital debt remains the sole responsibility of the spouse who incurred it. Filing for divorce in Illinois costs $250-$388 depending on your county, and at least one spouse must have lived in the state for 90 days before filing.

How Illinois Courts Classify Debt as Marital or Non-Marital
Illinois courts classify debt as either marital or non-marital before determining division under 750 ILCS 5/503(a). Marital debt includes all obligations incurred by either spouse during the marriage for the benefit of the household, regardless of whose name appears on the account. Non-marital debt includes obligations acquired before the marriage, after legal separation, or through inheritance or gift funds belonging solely to one spouse. The classification date matters significantly because debts incurred between separation and divorce filing may be disputed.
Under Illinois law, the timing of when debt was incurred determines its classification more than whose name is on the account. A credit card opened during the marriage in one spouse's name alone is still presumed marital debt if the charges were for household expenses. Conversely, a joint account opened before marriage containing pre-marital balances may have non-marital components that the original cardholder retains responsibility for paying.
The Illinois Family Expense Act (750 ILCS 65/15) creates joint liability for both spouses for medical bills and other family necessities incurred during marriage. This means medical debt, children's educational expenses, and household maintenance costs are almost always classified as marital debt, making both spouses equally responsible to creditors regardless of who incurred the specific charge.
The 12 Statutory Factors Illinois Courts Use to Divide Debt
Illinois courts apply 12 statutory factors under 750 ILCS 5/503(d) to achieve an equitable division of marital debt. These factors guide judges toward fair outcomes that consider each spouse's financial circumstances rather than simply splitting debts down the middle. Most Illinois divorce settlements result in divisions ranging from 50/50 to 70/30 depending on the specific circumstances of each case.
The statutory factors courts consider include the duration of the marriage, each spouse's contribution to acquiring marital property (including homemaker contributions), the value of property assigned to each spouse, the relevant economic circumstances of each spouse at the time of division, any obligations from prior marriages, prenuptial or postnuptial agreements, the age, health, and occupation of each party, custodial provisions for children, opportunities for future income acquisition, and the tax consequences of property division.
Illinois courts give equal weight to homemaker contributions under 750 ILCS 5/503(d)(1). A spouse who stayed home to raise children or manage the household while the other built a career is considered to have contributed equally to the marital estate. This means a non-working spouse will not automatically receive a larger debt burden simply because they earned less income during the marriage.
How Credit Card Debt Is Divided in Illinois Divorce
Credit card debt incurred during marriage is presumed marital debt in Illinois regardless of whose name appears on the account. Courts examine the purpose of the charges, not the account holder, when determining division. Credit card balances used for household expenses like groceries, utilities, and family vacations are typically split between both spouses, while individual purchases unrelated to the marriage may be assigned solely to the spouse who made them.
Joint credit card accounts present significant post-divorce risks because creditors are not bound by divorce decrees. Even if your divorce agreement assigns a joint credit card balance to your ex-spouse, the credit card company can still pursue you for the full amount if your ex fails to pay. Your divorce decree only creates a legal remedy against your ex-spouse for breach of the agreement; it does not remove your contractual liability to the creditor.
To protect yourself from joint credit card liability after divorce, consider these strategies before finalizing your settlement: pay off joint balances using marital assets, transfer balances to individual accounts in one spouse's name only, include indemnification language in your settlement agreement requiring the assigned spouse to hold you harmless from creditor collection, and close joint accounts immediately after transfer. Working with a divorce attorney to structure these protections can prevent credit damage and collection harassment years after your divorce is final.
Mortgage Debt Division: Who Pays for the Marital Home?
Mortgage debt typically follows the marital home in Illinois divorce under 750 ILCS 5/503. If one spouse keeps the home, they usually assume responsibility for the mortgage, often through refinancing. If neither spouse can afford the mortgage alone, the court may order the home sold with proceeds used to pay off the mortgage and any remaining equity divided between spouses according to the equitable distribution factors.
Refinancing the mortgage into the sole name of the spouse keeping the home is critical for protecting the departing spouse. Your divorce decree does not remove you from the mortgage loan because the lender was not a party to your divorce and is not bound by your settlement agreement. Until the mortgage is refinanced, both spouses remain liable. If the spouse keeping the house stops making payments, the lender can pursue the other spouse for the full balance and report missed payments on their credit.
During the divorce process, whoever is going to keep the house should begin making mortgage payments immediately. Illinois courts may award a greater share of home equity to the spouse who maintained mortgage payments during separation, particularly if the paying spouse no longer lived in the home. Courts view sole mortgage payments during litigation as evidence supporting a larger equity award under the contribution factors of 750 ILCS 5/503(d).
Student Loan Debt: Special Rules Apply
Student loans are treated uniquely in Illinois divorce, with most courts assigning educational debt to the spouse who obtained the degree regardless of when the loans were taken. The rationale is that the borrowing spouse receives the ongoing benefit of their education through enhanced earning capacity, making it equitable for them to bear the repayment burden. This practical approach recognizes that a degree cannot be divided like other marital property.
Student loans incurred before marriage are almost always classified as non-marital debt under 750 ILCS 5/503(a). The borrowing spouse entered the marriage already obligated on these loans, and the other spouse did not benefit from or contribute to the educational expenses. Pre-marital educational debt remains the sole responsibility of the original borrower in virtually all Illinois divorce cases.
Student loans taken during marriage may be treated differently depending on how the loan proceeds were used. If student loan funds were used for marital expenses such as housing, utilities, or groceries, courts may classify some portion as marital debt, making both spouses responsible. However, if the loans were used solely for tuition, books, and direct educational expenses, they remain the borrowing spouse's responsibility. If you co-signed your spouse's student loan refinance during marriage, you may be jointly liable for the refinanced balance regardless of whose education it funded.
Dissipation: When One Spouse Wastes Marital Assets
Dissipation occurs when one spouse uses marital funds for purposes unrelated to the marriage during the period when the marriage is undergoing an irreconcilable breakdown under 750 ILCS 5/503(d)(2). Common examples include gambling losses, spending on an extramarital affair, substance abuse expenditures, or recklessly destroying marital business assets. If proven, the court charges the dissipated amount against the offending spouse's share of the marital estate, effectively requiring them to reimburse the other spouse.
To make a dissipation claim, you must file a notice of intent at least 60 days before trial or 30 days after discovery closes, whichever is later. The notice must identify the specific property dissipated and the date or time period when the marriage began breaking down. Courts will not consider dissipation that occurred more than 5 years before the divorce petition was filed or more than 3 years after you should have known about the wasteful spending.
The burden of proof shifts once a dissipation claim is properly made. The accused spouse must prove by clear and specific evidence how the disputed marital funds were spent. General or vague statements about spending on marital expenses are insufficient to defeat a dissipation claim. If your spouse ran up $50,000 in credit card debt during separation on unexplained purchases, they must provide documentation showing the purchases benefited the marriage. Failure to provide adequate proof results in the dissipated amount being charged against their property division.
Business Debt and Commercial Loans
Business debt acquired during marriage is generally classified as marital debt if the business was a marital asset under 750 ILCS 5/503. Both spouses share responsibility for business loans, lines of credit, and unpaid business obligations regardless of whether only one spouse actively managed the business. Courts consider the business's contribution to marital income when dividing both the business asset and its associated liabilities.
Personal guarantees on business debt create individual liability that survives divorce. If you personally guaranteed a business loan during marriage, the lender can pursue you directly even if the divorce decree assigns the business and its debt to your spouse. Similar to mortgage refinancing, the business-owning spouse should refinance commercial loans to remove the non-operating spouse's personal guarantee as part of the divorce settlement.
If one spouse negligently or intentionally caused business failure during separation, dissipation claims may apply. Letting equipment rust, driving away customers, or failing to maintain required licenses could constitute dissipation if done while the marriage was breaking down. The non-operating spouse could recover their share of the business value that was destroyed through mismanagement, in addition to any division of remaining business assets.
Medical Debt and Family Expenses
Medical debt incurred during marriage is almost always classified as marital debt under the Illinois Family Expense Act (750 ILCS 65/15). Both spouses are jointly liable for necessary medical treatment obtained by either spouse or their children during the marriage. This includes hospital bills, physician charges, prescription costs, and mental health treatment. The marital classification applies even if only one spouse received treatment and the other had no involvement in obtaining care.
Children's medical expenses present particular challenges because ongoing treatment needs continue after divorce. Courts typically address both existing medical debt and provisions for future healthcare expenses in the parenting agreement. The spouse with primary health insurance coverage may be ordered to maintain coverage for the children, while extraordinary medical costs may be divided proportionally based on each parent's income.
Unpaid family expenses like utilities, childcare, and home repairs accrued during marriage are divided equitably along with other marital debt. Courts consider whether these expenses benefited the family as a whole when assigning responsibility. If one spouse accumulated utility debt while living separately during the divorce process, that post-separation debt may be treated differently than household expenses incurred while both spouses were living together.
Tax Debt and IRS Obligations
Tax debt from joint returns filed during marriage is generally considered marital debt in Illinois, with both spouses responsible for unpaid federal and state taxes. However, the IRS has separate rules that supersede divorce agreements. The IRS can collect the full amount from either spouse regardless of how your divorce decree allocates the debt. Your only protection if your ex fails to pay assigned tax debt is to pursue them in court for breach of the settlement agreement.
Innocent spouse relief may be available if your spouse underreported income or claimed improper deductions without your knowledge. IRS Form 8857 allows you to request relief from joint tax liability if you can prove you had no knowledge of the underreporting and that holding you liable would be inequitable. This federal remedy exists independently of your Illinois divorce and must be pursued directly with the IRS within specific time limits.
Tax debt division should be coordinated with your overall property settlement. If one spouse assumes a larger share of tax debt, they may be entitled to a larger share of marital assets to compensate. Courts consider the tax consequences of property transfers under 750 ILCS 5/503(d)(11), including depreciation recapture, capital gains triggers, and liquidity challenges that affect each spouse's ability to pay assigned debts.
Filing for Divorce in Illinois: Costs and Requirements
Filing for divorce in Illinois costs $250-$388 for the initial petition, with exact fees determined by your county of residence. Cook County charges the highest fee at $388, while DuPage County charges $348 and rural counties typically charge $250-$300. The responding spouse pays a separate appearance fee of $218-$251 to file their answer. Total court costs for an uncontested divorce range from $300-$500, while contested cases can exceed $2,000 in court costs before attorney fees. (Fees current as of March 2026. Verify with your local clerk before filing.)
At least one spouse must have been a resident of Illinois for a minimum of 90 days immediately preceding the filing of the divorce petition under 750 ILCS 5/401(a). Only one spouse needs to meet this requirement, meaning you can file in Illinois even if your spouse lives in another state. The divorce must be filed in the county where either spouse resides. Military personnel stationed in Illinois may satisfy the residency requirement through their military presence.
Fee waivers are available for individuals who cannot afford court costs under Illinois Supreme Court Rule 298. You qualify if your household income falls at or below 125% of the federal poverty guidelines. For 2026, this means annual income below approximately $18,500 for a single person, $25,000 for a household of two, or $37,500 for a family of four. Filing the appropriate fee waiver forms allows you to proceed with divorce without paying filing fees upfront.
Protecting Yourself from Your Spouse's Debt After Divorce
Your divorce decree creates obligations between you and your ex-spouse but does not bind third-party creditors. Creditors who were not parties to your divorce can pursue collection against any account holder or co-signer regardless of how your settlement assigned the debt. Understanding this critical distinction is essential for protecting your credit and finances after divorce.
Include specific indemnification language in your settlement agreement requiring the spouse who is assigned a debt to hold you harmless from any collection attempts by creditors. While this does not prevent creditor pursuit, it creates a clear legal remedy allowing you to sue your ex-spouse for any amounts you are forced to pay on their assigned debt, plus attorney fees and court costs.
Consider paying off or refinancing joint debts as part of your settlement rather than simply assigning them to one spouse. Using marital assets to eliminate joint credit card balances, refinancing the mortgage into one name, and closing joint accounts prevents future disputes and protects both parties' credit. The short-term cost of paying down debt may be far less than the long-term consequences of relying on your ex to honor settlement obligations.
