Should I Get a Legal Separation Instead of a Divorce?
Not every couple who wants time apart is ready to end a marriage for good. Some want space to think things through. Others can’t divorce for religious or personal reasons but still need to sort out money and parenting. A legal separation offers a gateway for couples to stay married while setting legal rules for support, parenting, and other issues.
If you’re thinking about a legal separation in 2026, a St. Charles, IL family law attorney can help you understand the potential benefits.
What Is the Difference Between a Legal Separation and a Divorce in Illinois?
A divorce, called a dissolution of marriage in Illinois, legally ends a marriage. Once it’s finalized, you’re no longer married, and you can’t undo it except by getting remarried.
In a legal separation, you and your spouse stay legally married while living apart. A court order can address temporary financial support and other issues. If you later decide to reconcile, you won’t need to remarry. If either spouse decides the marriage really is over, they can file for divorce.
How Do You Get a Legal Separation in Illinois?
To begin the process of getting a legal separation, you file a petition in the circuit court where you or your spouse lives or where you last lived together as a married couple (750 ILCS 5/402).
Once filed, the process looks similar to a divorce case in some ways. There’s a petition, a summons served on your spouse, and often a hearing before a judge. The court may order temporary support or other relief while the case is pending.
Unlike a divorce, a judge cannot value or divide property unless you and your spouse reach a property settlement agreement and ask the court to include it in the judgment. If the court approves the agreement, its property terms are final and cannot be changed later.
Many couples work out these terms through mediation rather than litigation. A neutral mediator can help you and your spouse negotiate parenting time and division of responsibilities as well as support and other financial terms. This is often simpler and more satisfactory for both parties than having a judge make decisions.
Why Might You Choose a Legal Separation Over a Divorce in Illinois?
Couples consider legal separation for a range of personal reasons. These often include:
- Religious or personal beliefs that make divorce difficult
- Uncertainty about whether divorce is the right long-term decision
- The possibility of keeping health insurance through a spouse’s employer plan, if the plan allows it
- Reaching 10 years of marriage, which can affect eligibility for divorced-spouse Social Security benefits
- Wanting to figure out parenting time and support now, while the marriage is still technically intact
A written separation agreement can also lay groundwork for a future divorce settlement. If you and your spouse later decide to divorce, you already have some information about whether the terms you’ve tried so far work or not. Some terms may be carried forward into the divorce decree, while others may be adjusted depending on the agreement and your circumstances. However, property terms included in the legal separation judgment are final and cannot be changed later.
Taxes can also be affected by whether you’re separated or divorced. Filing status, deductions, and how support payments are treated can all shift depending on your legal status at year’s end. If you have a final legal separation order on the last day of the year, the IRS generally treats you as unmarried for tax filing purposes. If you are only informally separated, the IRS generally still considers you married. Speak with a tax professional before deciding which option is best for you.
Can You Remarry While Legally Separated in Illinois?
You generally can’t remarry while legally separated. Because a legal separation doesn’t end your marriage, you’d need a court to grant a divorce first.
What Happens if You Don’t Formalize a Separation in Illinois?
Couples sometimes separate informally, without having a court order in place. This might be a fine arrangement if you are confident that your spouse will keep their word on agreements about finances and division of family responsibilities. However, this can leave important financial and parenting issues unresolved. Informal promises about support, parenting time, and bills can also be harder to enforce.
Living apart without putting these terms into a court order doesn’t create the same protections a legal separation does. Without a formal agreement or judgment, you and your spouse may still be financially tied through joint debts and accounts. A legal separation can put your terms in writing and give the court authority to enforce them. Simply living in different houses doesn’t do that.
Circumstances also might change after a couple separates in ways that are hard to predict. Income, changes in health coverage, or unexpected medical expenses can all have a big effect on a couple’s circumstances. Formal documentation of previous agreements between spouses can make it easier to address new circumstances going forward.
