Frequently Asked Questions

What qualifies as cohabitation for alimony purposes in Illinois?

Under Illinois law, cohabitation occurs when a maintenance recipient lives with another person on a resident, continuing conjugal basis. This means more than just sharing a residence—courts look for evidence of a marriage-like relationship including shared finances, domestic responsibilities, and presenting as a couple to others.

Does my ex-spouse's cohabitation automatically terminate alimony in Illinois?

Not automatically. While cohabitation on a conjugal basis creates a rebuttable presumption that maintenance should be modified or terminated, the receiving spouse can present evidence to counter this presumption. A court must still make the final determination based on all relevant factors.

How long does someone need to live together before it's considered cohabitation?

Illinois law requires the relationship to be on a 'continuing' basis, but there is no specific timeframe defined by statute. Courts consider the duration alongside other factors such as shared expenses, joint activities, and the nature of the relationship when determining whether cohabitation exists.

Can I stop paying alimony if my ex is just dating someone?

Simply dating someone typically does not qualify as cohabitation under Illinois law. To modify or terminate maintenance, you generally must demonstrate that your ex-spouse is living with their partner in a resident, continuing conjugal relationship—not merely spending occasional time together.

What evidence do I need to prove cohabitation in Illinois?

Useful evidence may include proof of shared residence (mail, utility bills, lease agreements), financial records showing pooled resources, witness testimony, photographs, social media posts showing the couple together, and any other documentation demonstrating a conjugal living arrangement.

Can my divorce agreement prevent termination of maintenance for cohabitation?

Possibly. Some divorce agreements include provisions that specifically address cohabitation and its effect on maintenance. It's important to carefully review your marital settlement agreement, as the terms you agreed to may impact your rights regarding cohabitation-based modifications.
